Congratulations on getting this far. :-)
Prerequisites: Python 1.5 or later
(http://www.python.org/)
RCS, Revision Control System
(http://www.cs.purdue.edu/homes/trinkle/RCS/)
read-only, physical access to a CVS repository
(See http://www.cvshome.org/ for more information)
Optional: a web server capable of running CGI programs
(for example, Apache at http://httpd.apache.org/)
GNU-diff to replace broken diff implementations
(http://www.gnu.org/software/diffutils/diffutils.html)
MySQL to create and query a commit database
(http://www.mysql.com/)
(http://sourceforge.net/projects/mysql-python)
(and Python 1.5.2 or later)
Enscript to colorize code displayed from the CVS repository
(http://people.ssh.com/mtr/genscript/)
CvsGraph for a graphical representation of the CVS revisions
(http://www.akhphd.au.dk/~bertho/cvsgraph/)
GUI Operation:
If you just want to see what your CVS repository looks like with
ViewCVS, type "./standalone.py -g -r /PATH/TO/CVS/ROOT". This
will start a tiny webserver serving at http://localhost:7467/.
Standard operation:
To start installing right away (on UNIX): type "./viewcvs-install"
in the current directory and answer the prompts. When it
finishes, edit the file viewcvs.conf in the installation directory
to tell viewcvs the paths to your CVS repositories. Next,
configure your web server to run <INSTALL>/cgi/viewcvs.cgi, as
appropriate for your web server. The section `INSTALLING VIEWCVS'
below is still recommended reading.
INSTALLING VIEWCVS
------------------
1) To get viewcvs.cgi to work, make sure that you have Python 1.5 or
greater installed and a webserver which is capable of executing
CGI scripts (either based on the .cgi extension, or by placing the
script within a specific directory).
1) To get viewcvs.cgi to work, make sure that you have Python 1.5.2
installed and a webserver which is capable to execute cgi-scripts
(either based on the .cgi extension, or by placing the script
within a specific directory).
You need to have RCS installed. Specifically, "rlog", "rcsdiff",
and "co". This script was tested against RedHat's rcs-5.7-10.rpm
Note, that the viewcvs.cgi script needs to have READ-ONLY, physical
access to the CVS repository (or a copy of it). Therefore, rsh/ssh or
pserver access to the repository will not work.
Note, that the viewcvs.cgi-script needs to have READ-ONLY, physical
access to the repository (or a copy of it). Therefore, rsh/ssh or
pserver access doesn't work yet.
For the more human readable diff formats you need a modern diff utility.
If you are using Linux, this is no problem. But on commercial unices
you might want to install GNU-diff to be able to use unified or
side-by-side diffs.
If you want to use cvsgraph, you have to obtain and install this
separately. See below. This was tested with cvsgraph-1.1.2.
For the checkin database to work, you will need MySQL >= 3.22,
and the Python DBAPI 2.0 module, MySQLdb. This was tested with
MySQLdb 0.9.1.
2) Installation is handled by the ./viewcvs-install script. Run this
script and you will be prompted for a installation root path.
The default is /usr/local/viewcvs-VERSION, where VERSION is
the version of this ViewCVS release. The installer sets the install
path in some of the files, and ViewCVS cannot be moved to a
different path after the install.
Note: while 'root' is usually required to create /usr/local/viewcvs,
ViewCVS does not have to be installed as root, nor does it run as root.
It is just as valid to place ViewCVS in a home directory, too.
Note: viewcvs-install will create directories if needed. It will
prompt before overwriting files that may have been modified (such
as viewcvs.conf), thus making it safe to install over the top of
a previous installation. It will always overwrite program files,
however.
3) Edit <VIEWCVS_INSTALLATION_DIRECTORY>/viewcvs.conf for your specific
configuration. In particular, examine the following configuration options:
2) Copy viewcvs.cgi to the cgi-script location of your web
server. Edit the file for your specific configuration. In
particular, examine the following configuration variables:
cvs_roots
default_root
rcs_path
mime_types_file
There are some other options that are usually nice to change. See
viewcvs.conf for more information. ViewCVS provides a working,
default look. However, if you want to customize the look of ViewCVS
then edit the files in <VIEWCVS_INSTALLATION_DIRECTORY>/templates.
You need knowledge about HTML to edit the templates.
If Python is not located in /usr/local/bin, then you'll need to
edit the first line of the file.
4) The CGI programs are in <VIEWCVS_INSTALLATION_DIRECTORY>/cgi/. You can
symlink to this directory from somewhere in your published HTTP server
path if your webserver is configured to follow symbolic links. You can
also copy the installed <VIEWCVS_INSTALLATION_DIRECTORY>/cgi/*.cgi scripts
after the install (unlike the other files in ViewCVS, the CGI scripts can
be moved).
ViewCVS has not been tested on the Win32 platform.
If you are using Apache, then the ScriptAlias directive is very
useful for pointing directly to the viwecvs.cgi script.
3) That's it. Try it out.
NOTE: for security reasons, it is not advisable to install ViewCVS
directly into your published HTTP directory tree (due to the MySQL
passwords in viewcvs.conf).
5) That's it for repository browsing. Instructions for getting the
SQL checkin database working are below.
WARNING: ViewCVS has not been tested on web servers operating on the
Win32 platform.
UPGRADING VIEWCVS
-----------------
Please read the file upgrading.html in the website subdirectory or
at <http://viewcvs.sourceforge.net/upgrading.html>.
SQL CHECKIN DATABASE
--------------------
This feature is a clone of the Mozilla Project's Bonsai database. It
catalogs every commit in the CVS repository into a SQL database. In fact,
the databases are 100% compatible.
Various queries can be performed on the database. After installing ViewCVS,
there are some additional steps required to get the database working.
1) You need MySQL >= 3.22, and the Python module MySQLdb 0.9.0 installed.
Python 1.5.2 is REQUIRED by MySQLdb, therefore to use this part of
ViewCVS you must be using Python 1.5.2. Additionally you will need the
mxDateTime extension. I've tested with version 1.3.0
2) You need to create a MySQL user who has permission to create databases.
Optionally, you can create a second user with read-only access to the
database.
3) Run the <VIEWCVS_INSTALLATION_DIRECTORY>/make-database script. It will
prompt you for your MySQL user, password, and the name of database you
want to create. The database name defaults to "ViewCVS". This script
creates the database and sets up the empty tables. If you run this on a
existing ViewCVS database, you will lose all your data!
4) Edit your <VIEWCVS_INSTALLATION_DIRECTORY>/viewcvs.conf file.
There is a [cvsdb] section. You will need to set:
host = # MySQL database server host
database_name = # the name of the database you created with
# make-database
user = # the read/write database user
passwd = # password for read/write database user
readonly_user = # the readonly database user -- it's pretty
# safe to use the read/write user here
readonly_passwd = # password for the readonly user
5) Two programs are provided for updating the checkin database,
cvsdbadmin and loginfo-handler. They serve two different purposes.
The cvsdbadmin program walks through your CVS repository and adds
every commit in every file. This is commonly used for initializing
the database from a repository which has been in use. The
loginfo-handler script is executed by the CVS server's CVSROOT/loginfo
system upon each commit. It makes real-time updates to the checkin
database as commits are made to the repository.
To build a database of all the commits in the CVS repository /home/cvs,
invoke: "./cvsdbadmin rebuild /home/cvs". If you want to update
the checkin database, invoke: "./cvsdbadmin update /home/cvs". The
update mode checks to see if a commit is already in the database,
and only adds it if it is absent.
To get real-time updates, you'll want to checkout the CVSROOT module
from your CVS repository and edit CVSROOT/loginfo. Add the line:
ALL (echo %{sVv}; cat) | <VIEWCVS_INSTALLATION_DIRECTORY>/loginfo-handler
If you have other scripts invoked by CVSROOT/loginfo, you will want
to make sure to change any running under the "DEFAULT" keyword to
"ALL" like the loginfo handler, and probably carefully read the
execution rules for CVSROOT/loginfo from the CVS manual.
6) You may want to modify the HTML template file:
<VIEWCVS_INSTALLATION_DIRECTORY>/templates/query.ezt
This is used by the query.cgi script to generate part of its HTML output.
At some point the currently hardcoded table output will also vanish.
7) You should be ready to go. Load up the query.cgi script and give
it a try.
ENSCRIPT CONFIGURATION
----------------------
Enscript is program that can colorize sourcecode of a lot of languages.
Linux distributions like for example SuSE Linux from at least 7.0
up to the recently released 7.3 already contain a precompiled and
configured enscript 1.6.2 package.
1) Download genscript from http://people.ssh.com/mtr/genscript/
2) Configure and compile per instructions with enscript.
(I 've not done this, since I'm using the precompiled package
delivered with SuSE Linux)
3) Set the 'use_enscript' option in viewcvs.conf to 1.
4) That's it!
5) If you want to colorize exotic languages, you might have to
patch 'lib/viewcvs.py' and add a new highlighting file to enscript.
I've done this for Modula-2 and submitted the file to the
enscript maintainer long ago. If interested in this patch for
enscript mailto:pefu@sourceforge.net
CVSGRAPH CONFIGURATION
----------------------
CvsGraph is a program that can display a clickable, graphical tree
of files in a CVS repository.
WARNING: Under certain circumstances (many revisions of a file
or many branches or both) cvsgraph can generate very huge images.
Especially on thin clients these images may crash the Web-Browser.
Currently there is no known way to avoid this behavior of cvsgraph.
So you have been warned!
Nevertheless cvsgraph can be quite helpful on repositories with
a reasonable number of revisions and branches.
1) Install viewcvs according to instructions in 'INSTALLING
VIEWCVS' section above. The installation directory is where
the 'viewcvs-install' script copied and configured the viewcvs
programs.
2) Download CvsGraph from http://www.akhphd.au.dk/~bertho/cvsgraph/
3) Configure and compile per instructions with CvsGraph. I had
problems with 'configure' finding the gd library. Had to create
a link from libgd.so to libgd.do.4.0.0. On Solaris you might
want to edit the link command line and add the option -R if
you have you libraries at non-standard location.
4) Place the 'cvsgraph' executable into a directory readable by the
userid running the web server. (default is '/usr/local/bin' if
you simply type 'make install' in the cvsgraph directory).
5) Check the setting of the 'cvsgraph_path' option in viewcvs.conf:
/usr/local/bin/ is most often NOT contained in $PATH of the
webserver process (e.g. Apache), so you will have to edit this.
Set the 'use_cvsgraph' option in viewcvs.conf to 1.
6) That's it!
7) There is a file <VIEWCVS_INSTALLATION_DIRECTORY>/cvsgraph.conf that
you may want to edit if desired to set color and font characteristics.
See the cvsgraph.conf documentation. No edits are required in
cvsgraph.conf for operation with viewcvs.

PREFACE
-------
This file will go away soon after release 0.8. Please use the SourceForge
tracker to resubmit any of the items listed below, if you think, it is
still an issue:
http://sourceforge.net/tracker/?group_id=18760
Before reporting please check, whether someone else has already done this.
Working patches increase the chance to be included into the next release.
-- PeFu / October 2001
TODO ITEMS
----------
*) add Tamminen Eero's comments on how to make Linux directly execute
the Python script. From email on Feb 19.
[ add other examples, such as my /bin/sh hack or the teeny CGI stub
importing the bulk hack ]
*) insert rcs_path into PATH before calling "rcsdiff". rcsdiff might
use "co" and needs to find it on the path.
*) show the "locked" flag (attach it to the LogEntry objects).
Idea from Russell Gordon <russell@hoopscotch.dhs.org>
*) committing with a specific revision number:
http://mailman.lyra.org/pipermail/viewcvs/2000q1/000008.html
*) add capability similar to cvs2cl.pl:
http://mailman.lyra.org/pipermail/viewcvs/2000q2/000050.html
suggestion from Chris Meyer <cmeyer@gatan.com>.
*) add a tree view of the directory structure (and files?)
*) include a ConfigParser.py to help older Python installations
*) add a check for the rcs programs/paths to viewcvs-install. clarify the
dependency on RCS in the docs.
*) have a "check" mode that verifies binaries are available on rcs_path
-> alternately (probably?): use rcsparse rather than external tools
KNOWN BUGS
----------
*) time.timezone seems to not be available on some 1.5.2 installs.
I was unable to verify this. On RedHat and SuSE Linux this bug
is non existant.
*) With old repositories containing many branches, tags or thousands
or revisions, the cvsgraph feature becomes unusable (see INSTALL).
ViewCVS can't do much about this, but it might be possible to
investigate the number of branches, tags and revision in advance
and disable the cvsgraph links, if the numbers exceed a certain
treshold.

Granny.py - display CVS annotations in HTML
with lines colored by code age in days.
Original Perl version by J. Gabriel Foster (gabe@sgrail.com)
Posted to info-cvs on 02/27/1997
You can still get the original shell archive here:
http://www.geocrawler.com/archives/3/382/1997/2/0/2103824/
Perl modifications for NT by Marc Paquette (marcpa@cam.org)
Python port and CGI modifications by Brian Lenihan (brianl@real.com)
From the original granny.pl README:
--
What is Granny? Why do I care?
Granny is a tool for viewing cvs annotation information graphically. Using
Netscape, granny indicates the age of lines by color. Red lines are new,
blue lines are old. This information can be very useful in determining
what lines are 'hot'. New lines are more likely to contain bugs, and this
is an easy way to visualize that information.
Requirements:
Netscape (version 2.0 or better)
Perl5
CVS 1.9 (1.8 should work, but I have not tried it.)
Installation:
Put granny somewhere in your path. You may need to edit the
first line to point to your perl5 binary and libraries.
What to do:
Run granny just like you would 'cvs annotate' for a single file.
granny thefile.C
To find out who is to blame for that new 'feature'.
granny -U thefile.C
For all your options:
granny -h
Questions, Comments, Assertions?
send e-mail to the author: Gabe Foster (gabe@sgrail.com)
Notes:
I'm not the first person to try this sort of display, I just read about it
in a magazine somewhere and decided that cvs had all the information
I needed. To whomever first had this idea, it's a great one.
Granny is free, please use it as you see fit. I give no warranties.
As a courtesy, I ask that you tell me about any modifications you have made,
and also ask that you acknowledge my work if you use Granny in your own
software.

Granny.py:
granny.py [-h][-d days][-i input][-o output][-DUV] file
-h: Get this help display.
-i: Specify the input file. (Use - for stdin.)
-o: Specify the output file. (Use - for stdout.)
-d: Specify the day range for the coloring.\n
-r: Specify the cvs revision of the file.
-D: Display the date the line was last edited.
-U Display the user that last edited the line.
-V: Display the version the line was last edited.
By default, granny.py executes cvs annotate on a FILE and
runs netscape to display the graphic.
It is assumed that cvs and Netscape (for command line version) are
in your path.
If granny.py is placed in the cgi-bin directory of your Web
server, it will act as a CGI script. The working directory
defaults to /usr/tmp, but it can be overridden in the class
constructor:
A = CGIAnnotate(tempdir='/tmp')
Required fields:
root The full path to the cvs root directory.
Name The module/filename of the annotated file.
Optional fields:
rev The cvs revision number to use. (default HEAD).
Set the following fields to display extra info:
showUser Display the user that last edited the line.
showVersion Display version that the line was last edited in.
showDate Display the date the line was last edited.
http://yourserver.yourdomain.com/cgi-bin/granny.py?root=/cvsroot&Name=module/file
TODO:
Add support for determining the MIME type of files and/or a binary check.
- easily done by parsing Apache (mime.conf) or Roxen (extensions) MIME
files.
Consider adding buttons to HTML for optional display fields.
Add support for launching other browsers.

# Information on ViewCVS is located at the following web site:

#
# BASIC CONFIGURATION
#
# For correct operation, you will probably need to change the following
# configuration variables:
#
# cvs_roots
# default_root
# rcs_path
# mime_types_file
#
# It is usually desirable to change the following variables:
#
# address
# main_title
# forbidden
#
# use_enscript
# use_cvsgraph
#
# For Python source colorization:
#
# py2html_path
#
# If your icons are in a special location:
#
# icons
#
# Also, review the .ezt templates in the templates/ directory to adjust them
# for your particular site.
#
#
# FORMAT INFORMATION
#
# This file is delineated by sections, specified in [brackets]. Within each
# section, are a number of configuration settings. These settings take the
# form of: name = value. Values may be continued on the following line by
# indenting the continued line.
#
# WARNING: indentation *always* means continuation. name=value lines should
# always start in column zero.
#
# Comments should always start in column zero, and are identified with "#".
#
# Certain configuration settings may have multiple values. These should be
# separated by a comma. The settings where this is allowed are noted below.
#
# Any other setting that requires special syntax is noted at that setting.
#
#---------------------------------------------------------------------------
[general]
#
# This setting specifies each of the CVS roots on your system and assigns
# names to them. Each root should be given by a "name: path" value. Multiple
# roots should be separated by commas.
#
cvs_roots =
Development : /home/cvsroot
# this is the name of the default CVS root.
default_root = Development
# uncomment if the RCS binaries are not on the standard path
#rcs_path = /usr/bin/
#
# This is a pathname to a MIME types file to help viewcvs to guess the
# correct MIME type on checkout.
#
# If you are having problems with the default guess on the MIME type, then
# uncomment this option and point it at a MIME type file.
#
# For example, you can use the mime.types from apache here:
#mime_types_file = /usr/local/apache/conf/mime.types
# This address is shown in the footer of the generated pages.
# It must be replaced with the address of the local CVS maintainer.
address = <a href="mailto:cvs-admin@insert.your.domain.here">No CVS admin address has been configured</a>

#
# This should contain a list of modules in the repository that should not be
# displayed (by default or by explicit path specification).
#
# This configuration can be a simple list of modules, or it can get quite
# complex:
#
# *) The "!" can be used before a module to explicitly state that it
# is NOT forbidden. Whenever this form is seen, then all modules will
# be forbidden unless one of the "!" modules match.
#
# *) Shell-style "glob" expressions may be used. "*" will match any
# sequence of zero or more characters, "?" will match any single
# character, "[seq]" will match any character in seq, and "[!seq]"
# will match any character not in seq.
#
# *) Tests are performed in sequence. The first match will terminate the
# testing. This allows for more complex allow/deny patterns.
#
# Tests are case-sensitive.
#
forbidden =
# Some examples:
#
# Disallow "example" but allow all others:
# forbidden = example
#
# Disallow "example1" and "example2" but allow all others:
# forbidden = example1, example2
#
# Allow *only* "example1" and "example2":
# forbidden = !example1, !example2
#
# Forbid modules starting with "x":
# forbidden = x*
#
# Allow modules starting with "x" but no others:
# forbidden = !x*
#
# Allow "xml", forbid other modules starting with "x", and allow the rest:
# forbidden = !xml, x*, !*
#
#
# This option provides a mechanism for custom key/value pairs to be
# available to templates. These are stored in key/value files (KV files).
#
# Pathnames to the KV files are listed here, specified as absolute paths
# or relative to this configuration file. The kV files follow the same
# format as this configuration file. It may have multiple, user-defined
# sections, and user-defined options in those sections. These are all
# placed into a structure available to the templates as:
#
# kv.SECTION.OPTION
#
# Note that an option name can be dotted. For example:
#
# [my_images]
# logos.small = /images/small-logo.png
# logos.big = /images/big-logo.png
#
# Templates can use these with a directive like: [kv.my_images.logos.small]
#
# Note that sections across multiple files will be merged. If two files
# have a [my_images] section, then the options will be merged together.
# If two files have the same option name in a section, then one will
# overwrite the other (it is unspecified regarding which "wins").
#
# To further categorize the KV files, and how the values are provided to
# the templates, a KV file name may be annotated with an additional level
# of dotted naming. For example:
#
# kv_files = [asf]kv/images.conf
#
# Assuming the same section as above, the template would refer to an image
# using [kv.asf.my_images.logos.small]
#
# Lastly, it is possible to use %lang% in the filenames to specify a
# substitution of the selected language-tag.
#
kv_files =
# example:
# kv_files = kv/file1.conf, kv/file2.conf, [i18n]kv/%lang%_data.conf
#
#
# The languages available to ViewCVS. There are several i18n mechanisms
# available:
#
# 1) using key/value extension system and reading KV files based on
# the selected language
# 2) GNU gettext to substitute text in the templates
# 3) using different templates, based on the selected language
#
# ### NOTE: at the moment, the GNU gettext style is not implemented
#
# This option is a comma-separated list of language-tag values. The first
# language-tag listed is the default language, and will be used if an
# Accept-Language header is not present in the request, or none of the
# user's requested languages are available. If there are ties on the
# selection of a language, then the first to appear in the list is chosen.
#
languages = en-us
# other examples:
#
# languages = en-us, de
# languages = en-us, en-gb, de
# languages = de, fr, en-us
#
#---------------------------------------------------------------------------
[templates]
#
# The templates are specified relative to the configuration file. Absolute
# paths may be used, if you want to keep these elsewhere.
#
# If %lang% occurs in the pathname, then the selected language will be
# substituted.
#
# Note: the selected language is defined by the "languages" item in the
# [general] section, and based on the request's Accept-Language

# SECURITY WARNING: Denial Of Service
#
# Since a user can enter the regular expression, it is possible for

"""Module to analyze Python source code; for syntax coloring tools.
Interface:
tags = fontify(pytext, searchfrom, searchto)
The 'pytext' argument is a string containing Python source code.
The (optional) arguments 'searchfrom' and 'searchto' may contain a slice in pytext.
The returned value is a list of tuples, formatted like this:
[('keyword', 0, 6, None), ('keyword', 11, 17, None), ('comment', 23, 53, None), etc. ]
The tuple contents are always like this:
(tag, startindex, endindex, sublist)
tag is one of 'keyword', 'string', 'comment' or 'identifier'
sublist is not used, hence always None.

Function get_close_matches(word, possibilities, n=3, cutoff=0.6):
Use SequenceMatcher to return list of the best "good enough" matches.
word is a sequence for which close matches are desired (typically a
string).
possibilities is a list of sequences against which to match word
(typically a list of strings).
Optional arg n (default 3) is the maximum number of close matches to
return. n must be > 0.
Optional arg cutoff (default 0.6) is a float in [0, 1]. Possibilities
that don't score at least that similar to word are ignored.
The best (no more than n) matches among the possibilities are returned
in a list, sorted by similarity score, most similar first.
>>> get_close_matches("appel", ["ape", "apple", "peach", "puppy"])
['apple', 'ape']
>>> import keyword
>>> get_close_matches("wheel", keyword.kwlist)
['while']
>>> get_close_matches("apple", keyword.kwlist)

Class SequenceMatcher
SequenceMatcher is a flexible class for comparing pairs of sequences of any
type, so long as the sequence elements are hashable. The basic algorithm
predates, and is a little fancier than, an algorithm published in the late
1980's by Ratcliff and Obershelp under the hyperbolic name "gestalt pattern
matching". The basic idea is to find the longest contiguous matching
subsequence that contains no "junk" elements (R-O doesn't address junk).
The same idea is then applied recursively to the pieces of the sequences to
the left and to the right of the matching subsequence. This does not yield
minimal edit sequences, but does tend to yield matches that "look right"
to people.
Example, comparing two strings, and considering blanks to be "junk":
>>> s = SequenceMatcher(lambda x: x == " ",
... "private Thread currentThread;",
... "private volatile Thread currentThread;")
>>>
.ratio() returns a float in [0, 1], measuring the "similarity" of the
sequences. As a rule of thumb, a .ratio() value over 0.6 means the
sequences are close matches:
>>> print round(s.ratio(), 3)
0.866
>>>
If you're only interested in where the sequences match,
.get_matching_blocks() is handy:
>>> for block in s.get_matching_blocks():
... print "a[%d] and b[%d] match for %d elements" % block
a[0] and b[0] match for 8 elements
a[8] and b[17] match for 6 elements
a[14] and b[23] match for 15 elements
a[29] and b[38] match for 0 elements
Note that the last tuple returned by .get_matching_blocks() is always a
dummy, (len(a), len(b), 0), and this is the only case in which the last
tuple element (number of elements matched) is 0.
If you want to know how to change the first sequence into the second, use
.get_opcodes():
>>> for opcode in s.get_opcodes():
... print "%6s a[%d:%d] b[%d:%d]" % opcode
equal a[0:8] b[0:8]
insert a[8:8] b[8:17]
equal a[8:14] b[17:23]
equal a[14:29] b[23:38]
See Tools/scripts/ndiff.py for a fancy human-friendly file differencer,
which uses SequenceMatcher both to view files as sequences of lines, and
lines as sequences of characters.
See also function get_close_matches() in this module, which shows how
simple code building on SequenceMatcher can be used to do useful work.
Timing: Basic R-O is cubic time worst case and quadratic time expected
case. SequenceMatcher is quadratic time for the worst case and has
expected-case behavior dependent in a complicated way on how many
elements the sequences have in common; best case time is linear.
SequenceMatcher methods:
__init__(isjunk=None, a='', b='')
Construct a SequenceMatcher.
Optional arg isjunk is None (the default), or a one-argument function
that takes a sequence element and returns true iff the element is junk.
None is equivalent to passing "lambda x: 0", i.e. no elements are
considered to be junk. For example, pass
lambda x: x in " \\t"
if you're comparing lines as sequences of characters, and don't want to
synch up on blanks or hard tabs.
Optional arg a is the first of two sequences to be compared. By
default, an empty string. The elements of a must be hashable.
Optional arg b is the second of two sequences to be compared. By
default, an empty string. The elements of b must be hashable.
set_seqs(a, b)
Set the two sequences to be compared.
>>> s = SequenceMatcher()
>>> s.set_seqs("abcd", "bcde")
>>> s.ratio()
0.75
set_seq1(a)
Set the first sequence to be compared.
The second sequence to be compared is not changed.
>>> s = SequenceMatcher(None, "abcd", "bcde")
>>> s.ratio()
0.75
>>> s.set_seq1("bcde")
>>> s.ratio()
1.0
>>>
SequenceMatcher computes and caches detailed information about the
second sequence, so if you want to compare one sequence S against many
sequences, use .set_seq2(S) once and call .set_seq1(x) repeatedly for
each of the other sequences.
See also set_seqs() and set_seq2().
set_seq2(b)
Set the second sequence to be compared.
The first sequence to be compared is not changed.
>>> s = SequenceMatcher(None, "abcd", "bcde")
>>> s.ratio()
0.75
>>> s.set_seq2("abcd")
>>> s.ratio()
1.0
>>>
SequenceMatcher computes and caches detailed information about the
second sequence, so if you want to compare one sequence S against many

find_longest_match(alo, ahi, blo, bhi)
Find longest matching block in a[alo:ahi] and b[blo:bhi].
If isjunk is not defined:
Return (i,j,k) such that a[i:i+k] is equal to b[j:j+k], where
alo <= i <= i+k <= ahi
blo <= j <= j+k <= bhi
and for all (i',j',k') meeting those conditions,
k >= k'
i <= i'
and if i == i', j <= j'
In other words, of all maximal matching blocks, return one that starts
earliest in a, and of all those maximal matching blocks that start
earliest in a, return the one that starts earliest in b.
>>> s = SequenceMatcher(None, " abcd", "abcd abcd")
>>> s.find_longest_match(0, 5, 0, 9)
(0, 4, 5)
If isjunk is defined, first the longest matching block is determined as
above, but with the additional restriction that no junk element appears
in the block. Then that block is extended as far as possible by
matching (only) junk elements on both sides. So the resulting block
never matches on junk except as identical junk happens to be adjacent
to an "interesting" match.
Here's the same example as before, but considering blanks to be junk.
That prevents " abcd" from matching the " abcd" at the tail end of the
second sequence directly. Instead only the "abcd" can match, and
matches the leftmost "abcd" in the second sequence:
>>> s = SequenceMatcher(lambda x: x==" ", " abcd", "abcd abcd")
>>> s.find_longest_match(0, 5, 0, 9)
(1, 0, 4)
If no blocks match, return (alo, blo, 0).
>>> s = SequenceMatcher(None, "ab", "c")
>>> s.find_longest_match(0, 2, 0, 1)
(0, 0, 0)
get_matching_blocks()
Return list of triples describing matching subsequences.
Each triple is of the form (i, j, n), and means that
a[i:i+n] == b[j:j+n]. The triples are monotonically increasing in i
and in j.
The last triple is a dummy, (len(a), len(b), 0), and is the only triple
with n==0.
>>> s = SequenceMatcher(None, "abxcd", "abcd")
>>> s.get_matching_blocks()
[(0, 0, 2), (3, 2, 2), (5, 4, 0)]
get_opcodes()
Return list of 5-tuples describing how to turn a into b.
Each tuple is of the form (tag, i1, i2, j1, j2). The first tuple has
i1 == j1 == 0, and remaining tuples have i1 == the i2 from the tuple
preceding it, and likewise for j1 == the previous j2.
The tags are strings, with these meanings:
'replace': a[i1:i2] should be replaced by b[j1:j2]
'delete': a[i1:i2] should be deleted.
Note that j1==j2 in this case.
'insert': b[j1:j2] should be inserted at a[i1:i1].
Note that i1==i2 in this case.
'equal': a[i1:i2] == b[j1:j2]
>>> a = "qabxcd"
>>> b = "abycdf"
>>> s = SequenceMatcher(None, a, b)
>>> for tag, i1, i2, j1, j2 in s.get_opcodes():
... print ("%7s a[%d:%d] (%s) b[%d:%d] (%s)" %
... (tag, i1, i2, a[i1:i2], j1, j2, b[j1:j2]))
delete a[0:1] (q) b[0:0] ()
equal a[1:3] (ab) b[0:2] (ab)
replace a[3:4] (x) b[2:3] (y)
equal a[4:6] (cd) b[3:5] (cd)
insert a[6:6] () b[5:6] (f)
ratio()
Return a measure of the sequences' similarity (float in [0,1]).
Where T is the total number of elements in both sequences, and M is the
number of matches, this is 2,0*M / T. Note that this is 1 if the
sequences are identical, and 0 if they have nothing in common.
.ratio() is expensive to compute if you haven't already computed
.get_matching_blocks() or .get_opcodes(), in which case you may want to
try .quick_ratio() or .real_quick_ratio() first to get an upper bound.
>>> s = SequenceMatcher(None, "abcd", "bcde")
>>> s.ratio()
0.75
>>> s.quick_ratio()
0.75
>>> s.real_quick_ratio()
1.0
quick_ratio()
Return an upper bound on .ratio() relatively quickly.
This isn't defined beyond that it is an upper bound on .ratio(), and
is faster to compute.
real_quick_ratio():
Return an upper bound on ratio() very quickly.
This isn't defined beyond that it is an upper bound on .ratio(), and
is faster to compute than either .ratio() or .quick_ratio().

"""ezt.py -- easy templating
ezt templates are very similar to standard HTML files. But additionaly
they contain directives sprinkled in between. With these directives
it possible to generate the dynamic content from the ezt templates.
These directives are enclosed in square brackets. If you are a
C-programmer, you might be familar with the #ifdef directives of the
C preprocessor 'cpp'. ezt provides a similar concept for HTML. Additionally
EZT has a 'for' directive, which allows to iterate (repeat) certain
subsections of the template according to sequence of data items
provided by the application.
The HTML rendering is performed by the method generate() of the Template
class. Building template instances can either be done using external
EZT files (convention: use the suffix .ezt for such files):
>>> template = Template("../templates/log.ezt")
or by calling the parse() method of a template instance directly with
a EZT template string:
>>> template = Template()
>>> template.parse('''<html><head>
... <title>[title_string]</title></head>
... <body><h1>[title_string]</h1>
... [for a_sequence] <p>[a_sequence]</p>
... [end] <hr>
... The [person] is [if-any state]in[else]out[end].
... </body>
... </html>
... ''')
The application should build a dictionary 'data' and pass it together
with the output fileobject to the templates generate method:
>>> data = {'title_string' : "A Dummy Page",
... 'a_sequence' : ['list item 1', 'list item 2', 'another element'],
... 'person': "doctor",
... 'state' : None }
>>> import sys
>>> template.generate(sys.stdout, data)
<html><head>
<title>A Dummy Page</title></head>
<body><h1>A Dummy Page</h1>
<p>list item 1</p>
<p>list item 2</p>
<p>another element</p>
<hr>
The doctor is out.
</body>
</html>
Directives
==========
Several directives allow the use of dotted qualified names refering to objects
or attributes of objects contained in the data dictionary given to the
.generate() method.
Simple directives
-----------------
[QUAL_NAME]
This directive is simply replaced by the value of identifier from the data
dictionary. QUAL_NAME might be a dotted qualified name refering to some
instance attribute of objects contained in the dats dictionary.
Numbers are converted to string though.
[include "filename"] or [include QUAL_NAME]
This directive is replaced by content of the named include file.
Block directives
----------------
[for QUAL_NAME] ... [end]
The text within the [for ...] directive and the corresponding [end]
is repeated for each element in the sequence referred to by the qualified
name in the for directive. Within the for block this identifiers now
refers to the actual item indexed by this loop iteration.
[if-any QUAL_NAME] ... [else] ... [end]
Test if the value QUAL_NAME is not None or an empty string or list.
The [else] clause is optional. CAUTION: Numeric values are converted to string,
so if QUAL_NAME refers to a numeric value 0, the then-clause is
substituted!
[if-index odd] ... [else] ... [end]
[if-index even] ... [else] ... [end]
[if-index first] ... [else] ... [end]
[if-index last] ... [else] ... [end]
[if-index NUMBER] ... [else] ... [end]
These five directives work similar to [if-any], but are only useful
within a [for ...]-block (see above). The odd/even directives are
for example useful to choose different background colors for adjacent rows
in a table. Similar the first/last directives might be used to
remove certain parts (for example "Diff to previous" doesn't make sense,
if there is no previous).
[is QUAL_NAME STRING] ... [else] ... [end]
[is QUAL_NAME QUAL_NAME] ... [else] ... [end]
The [is ...] directive is similar to the other conditional directives
above. But it allows to compare two value references or a value reference
with some constant string.

"""ndiff [-q] file1 file2
or
ndiff (-r1 | -r2) < ndiff_output > file1_or_file2
Print a human-friendly file difference report to stdout. Both inter-
and intra-line differences are noted. In the second form, recreate file1
(-r1) or file2 (-r2) on stdout, from an ndiff report on stdin.
In the first form, if -q ("quiet") is not specified, the first two lines
of output are
-: file1
+: file2
Each remaining line begins with a two-letter code:
"- " line unique to file1
"+ " line unique to file2
" " line common to both files
"? " line not present in either input file
Lines beginning with "? " attempt to guide the eye to intraline
differences, and were not present in either input file. These lines can be
confusing if the source files contain tab characters.
The first file can be recovered by retaining only lines that begin with
" " or "- ", and deleting those 2-character prefixes; use ndiff with -r1.
The second file can be recovered similarly, but by retaining only " " and
"+ " lines; use ndiff with -r2; or, on Unix, the second file can be
recovered by piping the output through
sed -n '/^[+ ] /s/^..//p'
See module comments for details and programmatic interface.
"""
__version__ = 1, 6, 1
# SequenceMatcher tries to compute a "human-friendly diff" between
# two sequences (chiefly picturing a file as a sequence of lines,
# and a line as a sequence of characters, here). Unlike e.g. UNIX(tm)
# diff, the fundamental notion is the longest *contiguous* & junk-free
# matching subsequence. That's what catches peoples' eyes. The
# Windows(tm) windiff has another interesting notion, pairing up elements
# that appear uniquely in each sequence. That, and the method here,
# appear to yield more intuitive difference reports than does diff. This
# method appears to be the least vulnerable to synching up on blocks
# of "junk lines", though (like blank lines in ordinary text files,
# or maybe "<P>" lines in HTML files). That may be because this is
# the only method of the 3 that has a *concept* of "junk" <wink>.
#
# Note that ndiff makes no claim to produce a *minimal* diff. To the
# contrary, minimal diffs are often counter-intuitive, because they
# synch up anywhere possible, sometimes accidental matches 100 pages
# apart. Restricting synch points to contiguous matches preserves some
# notion of locality, at the occasional cost of producing a longer diff.
#
# With respect to junk, an earlier version of ndiff simply refused to
# *start* a match with a junk element. The result was cases like this:
# before: private Thread currentThread;
# after: private volatile Thread currentThread;
# If you consider whitespace to be junk, the longest contiguous match
# not starting with junk is "e Thread currentThread". So ndiff reported
# that "e volatil" was inserted between the 't' and the 'e' in "private".
# While an accurate view, to people that's absurd. The current version
# looks for matching blocks that are entirely junk-free, then extends the
# longest one of those as far as possible but only with matching junk.
# So now "currentThread" is matched, then extended to suck up the
# preceding blank; then "private" is matched, and extended to suck up the
# following blank; then "Thread" is matched; and finally ndiff reports
# that "volatile " was inserted before "Thread". The only quibble
# remaining is that perhaps it was really the case that " volatile"
# was inserted after "private". I can live with that <wink>.
#
# NOTE on junk: the module-level names
# IS_LINE_JUNK
# IS_CHARACTER_JUNK
# can be set to any functions you like. The first one should accept
# a single string argument, and return true iff the string is junk.
# The default is whether the regexp r"\s*#?\s*$" matches (i.e., a
# line without visible characters, except for at most one splat).
# The second should accept a string of length 1 etc. The default is
# whether the character is a blank or tab (note: bad idea to include
# newline in this!).
#
# After setting those, you can call fcompare(f1name, f2name) with the
# names of the files you want to compare. The difference report
# is sent to stdout. Or you can call main(args), passing what would
# have been in sys.argv[1:] had the cmd-line form been used.

Takes the input, assuming it is Python code and formats it into
colored HTML. When called without parameters the script tries to
work in CGI mode. It looks for a field 'script=URL' and tries to
use that URL as input file. If it can't find this field, the path
info (the part of the URL following the CGI script name) is
tried. In case no host is given, the host where the CGI script
lives and HTTP are used.

<p>
Select your parameters for querying the CVS commit database. You
can search for multiple matches by typing a comma-seperated list
into the text fields. Regular expressions, and wildcards are also
supported. Blank text input fields are treated as wildcards.
</p>
<p>
Any of the text entry fields can take a comma-seperated list of
search arguments. For example, to search for all commits from
authors <i>jpaint</i> and <i>gstein</i>, just type: <b>jpaint,
gstein</b> in the <i>Author</i> input box. If you are searching
for items containing spaces or quotes, you will need to quote your
request. For example, the same search above with quotes is:
<b>"jpaint", "gstein"</b>.
</p>
<p>
Wildcard and regular expression searches are entered in a similar
way to the quoted requests. You must quote any wildcard or
regular expression request, and a command charactor preceeds the
first quote. The command charactor <b>l</b> is for wildcard
searches, and the wildcard charactor is a percent (<b>%</b>). The
command charactor for regular expressions is <b>r</b>, and is
passed directly to MySQL, so you'll need to refer to the MySQL
manual for the exact regex syntax. It is very similar to Perl. A
wildard search for all files with a <i>.py</i> extention is:
<b>l"%.py"</b> in the <i>File</i> input box. The same search done
with a regular expression is: <b>r".*\.py"</b>.
</p>
<p>
All search types can be mixed, as long as they are seperated by
commas.

<p>
Contributions to ViewCVS are very welcome.
</p>
<h2>Getting Started</h2>
<p>
Some basic knowledge about <a href="http://www.python.org"><i>Python</i></a> and
development Tools like <code>diff</code> is required. Best is you start
with a fresh snapshot, which you may obtain from the
<a href="http://sourceforge.net/cvs/?group_id=18760">CVS-Repository</a>
at SourceForge.
</p>
<h2>Testing and reporting</h2>
<p>
Testing usability and the installation process on different platforms is
also a valuable contribution. Please report your results back to
us developers. But always tell us, which version of ViewCVS
you used on which platform.
</p><p>
If you are using the latest current development version please note
the date of your latest download or cvs update when reporting.
</p>
<h2>Does a Certain Coding Style Guide apply?</h2>
<p>
Maintain whatever style is present in the code being modified. New
code can use anything sane (which generally means
<a href="http://python.sourceforge.net/peps/pep-0008.html"><i>PEP&nbsp;8</i></a>).
Greg's only real peeve is if someone writes a function call as:
<code>some_func&nbsp;(args)</code> -- that space is Huge Badness.
Otherwise... <i>shrug</i>.
</p>
<h2>Submitting patches</h2>
<p>
Please use the
<a href="http://sourceforge.net/tracker/?func=add&group_id=18760&atid=318760">SourceForge&nbsp;project&nbsp;patch&nbsp;manager</a>
to submit your patches. Unified context diffs relative to the latest
development version are preferred.
</p><p>
If you have commit access, then you should know what
you're doing. Just make changes directly. Subscribing to
the <a href="http://mailman.lyra.org/mailman/listinfo/viewcvs-dev"><i>developer&nbsp;mailing&nbsp;list</i></a>
is recommended in any case.
</p>
<h2>Preserving security</h2>
<p>
Since ViewCVS is used in the internet, security is a major issue.
If you need to pass data from the request into an external program,
please don't use <code>os.system()</code> or <code>os.popen()</code>.
Please use the module <code>lib/popen</code> that comes with ViewCVS
instead.
</p>
<h2>Adding new features</h2>
<p>
If a new file or module is added, a new line in the installer program
<code>viewcvs-install</code> is required.
</p><p>
The library subdirectory contains a module <code>debug</code>, which may
useful to make performance tests.
</p><p>
If you need a new configuration option think carefully, into
which section it belongs. Try to keep the content of
<code>cgi/viewcvs.conf.dist</code> file and the library module
<code>lib/config.py</code> in sync.
</p>
<h2>Hacking on templates</h2>
<p>
The library module <code>ezt</code> contains a module doc string which
describes the directives used in the HTML templates, which can be found
in the <code>templates</code> sub directory.
</p>
<h2>Cutting a release</h2>
<p>
Also there actually is a script <code>tools/make-release</code>,
which creates a release directory, all other steps required to get
a ViewCVS release out of the door will be currently executed manually
by Greg Stein.
</p><p>
Nevertheless in case he ever wants to retire from this job, it is
probably a good idea to write the procedure down here:
<ol>
<li>Add a new subsection to the file
<code>website/upgrading.html</code> describing all user visible
changes for users of previous releases of ViewCVS.
<li>Test, Test, Test! At the time of this writing (0.8-dev) there
is no automatic testsuite available. So just run with permuting
different <code>viewcvs.conf</code> settings and ... pray.
<li>Review any <a
href="http://sourceforge.net/tracker/?atid=118760&group_id=18760&func=browse">
bug reports, that are still marked open.</a>
<li>Edit the file <code>lib/viewcvs.py</code> and remove the
<tt>"-dev"</tt> suffix from <code>__version__</code>. The remainder
should be of the form X.Y, where X is a positive number and
Y is a single digit.
<li>commit this changed version of <code>lib/viewcvs.py</code>
and than <code>cvs tag V</code><i>X</i><code>_</code><i>Y</i>, where
<i>X</i> and <i>Y</i> should be replaced by the release number
from above. If a developer is willing to volunteer as a
bug fix patch release manager, it is now possible to start here
at this point with a feature freezed branch using the command
<blockquote>
<code>cvs tag -b V</code><i>X</i><code>_</code><i>Y</i><code>_maint</code>
</blockquote>
<li>go into an empty directory and run the command:
<blockquote>
<code>tools/make-release V</code><i>X_Y</i> <code>viewcvs-</code><i>X.Y</i>
</blockquote>
This step requires anonymous CVS access to repository at SourceForge.
<li>pack the content of this <code>viewcvs-</code><i>X.Y</i> directory
into a tarball.
<li>Upload the created tarball into the download files section of the
ViewCVS project at SourceForge.
<br><b>Greg:</b><i>Could you please elaborate this step?</i>
<li>Edit the file <code>lib/viewcvs.py</code> again and this time
increment the <code>__version__</code> for the next release cycle,
again append the <code>"-dev"</code> to the version and again
<blockquote>
<code>cvs commit -m "new release cycle begins" lib/viewcvs.py</code>.
</blockquote>
<li>Write an announcement explaining all the cool new features
and put it out to:
<ul>
<li><a href="http://www.freshmeat.net"><i>www.freshmeat.net</i></a>
<li><a href="http://www.vex.net/parnassus/apyllo.py?i=91022454"><i>Vaults of Parnassus</i></a>
<li><a href="news:comp.lang.python">comp.lang.python</a>
<li><i>Where else? I dunno. Suggestions welcome.</i>
</ul>

Select your parameters for querying the CVS commit database in the
form at the top of the page. You
can search for multiple matches by typing a comma-seperated list
into the text fields. Regular expressions, and wildcards are also
supported. Blank text input fields are treated as wildcards.
</p>
<p>
Any of the text entry fields can take a comma-seperated list of
search arguments. For example, to search for all commits from
authors <i>jpaint</i> and <i>gstein</i>, just type: <code>jpaint,
gstein</code> in the <i>Author</i> input box. If you are searching
for items containing spaces or quotes, you will need to quote your
request. For example, the same search above with quotes is:
<code>"jpaint", "gstein"</code>.
</p>
<p>
Wildcard and regular expression searches are entered in a similar
way to the quoted requests. You must quote any wildcard or
regular expression request, and a command character preceeds the
first quote. The command character <code>l</code>(lowercase L) is for wildcard
searches, and the wildcard character is a percent (<code>%</code>). The
command character for regular expressions is <code>r</code>, and is
passed directly to MySQL, so you'll need to refer to the MySQL
manual for the exact regex syntax. It is very similar to Perl. A
wildard search for all files with a <i>.py</i> extention is:
<code>l"%.py"</code> in the <i>File</i> input box. The same search done
with a regular expression is: <code>r".*\.py"</code>.
</p>
<p>
All search types can be mixed, as long as they are seperated by
commas.

<p><b>ViewCVS</b> is a WWW interface for CVS Repositories.</b>
You can browse the
file hierarchy by picking directories (which have slashes after
them, <i>e.g.</i>, <b>src/</b>). If you pick a file, you will see
the revision history for that file. Selecting a revision number
will display that revision of the file. There is a link at each
revision to display diffs between that revision and the previous
one, and a form at the bottom of the page that allows you to
display diffs between arbitrary revisions.

<h1>ViewCVS: Viewing CVS Repositories</h1>
<p>
The ViewCVS software was inspired by
<a href="http://linux.fh-heilbronn.de/~zeller/cgi/cvsweb.cgi"><i>cvsweb</i></a>
(by <a href="mailto:zeller@think.de">Henner Zeller</a>).
I wanted to make some changes and updates, but cvsweb was
implemented in Perl (and rather poorly, IMO). So I undertook the
task to convert the software to Python.
</p>
<p>
ViewCVS can browse directories, change logs, and specific
revisions of files. It can display diffs between versions and
show selections of files based on tags or branches. In addition,
ViewCVS has "annotation" or "blame" support, Bonsai-like query
facilities, template-based page generation, and support for
individually configuring virtual hosts.
It also includes support for
<a href="http://www.akhphd.au.dk/~bertho/cvsgraph/"><i>CvsGraph</i></a>
-- a program to display the tree of revisions and branches
graphically.
show selections of files based on tags or branches.
</p>
<p>
Currently, the functionality of ViewCVS surpasses that of cvsweb.
See <a href="#Cvsweb">below</a> for a list of additional features.
ViewCVS is currently at version 0.2. It is almost a straight
port of the cvsweb script, but has had numerous cleanups and other
modifications, based on some of Python's strengths. There is
still some "badness" in there, but I've been working on flushing
that out, along with my work to start adding features. The
functionality of ViewCVS is equal to that of cvsweb, minus the
"annotation" support. Annotation requires read/write access to
the CVS repository (at this time), and I believe that is a
Bad Thing to do. One of my tasks will be eliminating the
read/write requirement.
</p>
<hr width="75&#37;">
<h2><a name="History">History</a></h2>
<p>
The ViewCVS software was inspired by
<a href="http://stud.fh-heilbronn.de/~zeller/cgi/cvsweb.cgi/"><i>cvsweb</i></a>
(originally written by Bill Fenner and then further developed by
<a href="mailto:zeller@think.de">Henner Zeller</a>).
Greg Stein wanted to make some changes and updates, but cvsweb was
implemented in Perl. He wrote:
<blockquote><i>While I can manage some Perl, cvsweb was
rather unmaintainable for me. So I undertook the
task to convert the software to
<a href="http://www.python.org/">Python</a>. As a result,
I've actually been able to go <em>way</em> beyond the simple
changes that I had envisioned.
</i></blockquote>
</p>
<p>
ViewCVS started as a port of the cvsweb script, but has had
numerous cleanups and other modifications, based on some of
Python's strengths. There is still some minor "badness"
remaining from the Perl code, but Greg has been working on
flushing that out, while adding new features.
</p>
<p>
ViewCVS has been developed by the <a href="who.html">ViewCVS
Group</a> and is made available under a
<a href="license-1.html">BSD-type license</a>.
</p>
<p>
ViewCVS requires <strong>Python 1.5</strong> or later (Python
1.5 has been out for a couple years and is readily available for
your favorite operating system). If you choose to use the SQL Checkin
Database feature, then you must use <strong>Python 1.5.2</strong>
or later and have the
<a href="http://sourceforge.net/projects/mysql-python"><i>MySQLdb
module</i></a> installed which itself requires

<h2><a name="Cvsweb">Additional features over cvsweb</a></h2>
<ul>
<li>
Template support: you can now customize the look and feel of
ViewCVS by editing the provided EZT templates, which are used
to generate the pages.
</li>
<li>
Internationalization support: ViewCVS will parse and handle
the Accept-Language request header, and can select different
inputs for localized page generation.
</li>
<li>
Colorization for many file types via <code>enscript</code>.
</li>
<li>
Bonsai-like query features. (Requires MySQL and some other
prerequisites)
</li>
<li>
Annotation/blame viewing support against a <strong>read-only</strong>
repository.
</li>
<li>
Configuration on a per-virtual-host basis. This allows you
to share the configuration file and ViewCVS installation
across virtual hosts, yet still be able to fine-tune the
options when necessary.
</li>
<li>
Automatic generation of tarballs for the HEAD or a specified
tag.
</li>
<li>
Runs either as CGI script, called from an installed web server
(such as <a href="http://httpd.apache.org/"><i>Apache</i></a>),
or as a standalone server.
</li>
<li>
Searching files for matches for a regular expression.
</li>
<li>Better reporting for unreadable files.</li>
<li>
More robust when given varying <code>rcsdiff</code> or
<code>rlog</code> outputs.
</li>
<li>Hard breaks in human-readable diffs.</li>
<li>
The configuration file is optional (you can change the values
right in the CGI script and avoid the config file, if you so
choose). The config file syntax is also cleaner, since it is
human-manageable rather than source code.
</li>
<li>
Directories with a large number of files can be viewed.
</li>
<li>
<strong>Security</strong>: ViewCVS only requires read access
to the CVS repository (not read/write). With the correct
security partitioning, this means that even if ViewCVS were to
be subverted, your source code is safe. Further, ViewCVS does
not use any <code>system()</code> or <code>popen()</code>
calls, which are very susceptible to abuse.
<br>
<small>(cvsweb had a hole due to a popen() call)</small>
</li>
<li>
Last but not least: it doesn't suffer from the "unmaintainable
code effect" that hits most Perl projects sooner or later:
<blockquote><i>[Perl] combines all the worst aspects of C and Lisp:
a billion different sublanguages in one monolithic executable.
It combines the power of C with the readability of PostScript.</i>

<h2><a name="Future">Future features, directions</a></h2>
<p>
ViewCVS is a Open Source project. So any future development depends
on the contributions that will be made by its user community.
Certainly working patches have a greater chance to become realized
quickly than feature requests. <i>But don't hesitate to submit your
suggestions! Send mail to the
<a href="mailto:viewcvs@lyra.org">viewcvs@lyra.org</a>
mailing list or even better use the
<a href="http://sourceforge.net/tracker/?func=add&group_id=18760&atid=368760">SF&nbsp;tracker</a>.
</i>
</p>
<ul>
<li>See the feature requests already submitted through
the <a href="http://sourceforge.net/tracker/?atid=368760&group_id=18760&func=browse">SF feature request tracker</a>
</li>
<li>UI streamlining/simplification</li>
<li>Integration with CVS checkin auto-mail scripts</li>
<li>Tighter integration with the query features</li>
<p>
</ul>
<h2>FAQ</h2>
<p>
And another longer term pet of Greg Stein:
</p>
<ul>
<li>Integration with an indexer such as LXR</li>
</ul>
</p>
<dl>
<!-- one of (dd dt) -->
<dt><strong>I got an <code>AttributeError: urlencode</code></strong></dt>
<dd>
If you see the following traceback in your browser:
<blockquote>
<pre>
Traceback (innermost last):
File "/home/httpd/cgi-bin/viewcvs.cgi", line 2205, in ?
main()
File "/home/httpd/cgi-bin/viewcvs.cgi", line 2123, in main
query_string = sticky_query(query_dict)
File "/home/httpd/cgi-bin/viewcvs.cgi", line 444, in sticky_query
bare_query = urllib.urlencode(sticky_dict)
AttributeError: urlencode
</pre>
</blockquote>
This is indicative of using an earlier version of
Python. <code>urllib.urlencode()</code> was introduced in
Python 1.5.2.
</dd>
</dl>
<hr width="75&#37;">
<h2><a name="Colorize">Colorization of files</a></h2>
<p>
ViewCVS can make use of the <code>enscript</code> program to
colorize files in the CVS repository. If <code>enscript</code>
is present on your system, then set the
<code>use_enscript</code> option in the
<code>viewcvs.conf</code> configuration file to <code>1</code>.
If necessary,
update the <code>enscript_path</code> option to point to your
installation directory. ... That's it! Now, as you view files
through ViewCVS, they will be colored.
</p>
<h3>Colorization of Python files</h3>
<p>
ViewCVS currently also comes with a builtin colorizer for Python
source files. This may go away in a future version, given the new
<code>enscript</code> support...
</p>
<p>
Christophe Pelte suggested this feature: colorize Python source
files using
<a href="http://starship.python.net/crew/lemburg/SoftwareDescriptions.html#py2html.py"><i>py2html</i></a>
(by Marc-Andrew Lemburg, based on
<a href="http://starship.python.net/crew/just/code/PyFontify.py"><i>PyFontify</i></a>
by Just van Rossum). I've added this feature to ViewCVS 0.3,
along with a generalized plugin mechanism for custom coloring other
types of files. See the instructions within the viewcvs.cgi for
setting the <code>py2html_path</code> configuration variable if
you want to use this feature.

<p>
This document describes some of the things that you will need to
consider, change, or handle when upgrading an existing ViewCVS
installation to a newer version.
</p>
<p>
It is always recommended to install the new version in a fresh directory
and to carefully compare the configuration files. A possible approach
is to name the directories <code>/usr/local/viewcvs-0.6</code>,
<code>/usr/local/viewcvs-0.7</code> and so on and than create a
symbolic link <code>viewcvs</code> pointing to the production
version. This way you can easily test several versions and switch
back, if your users start to complain.

<li><a href="#from7">Upgrading from ViewCVS 0.7 or earlier</a></li>
</ul>
<hr>
<h2><a name="from8">Upgrading from ViewCVS 0.8</a></h2>
<p>
This section discusses how to upgrade ViewCVS 0.8 to version
0.9 or a later version of the software.
</p>
<h3>Configuration Options</h3>
<p>
More templates were introduced in version 0.8 of the software,
which made many of the configuration options obsolete. This
section covers which options were removed. If you made any
changes to these options, then you will need to make
corresponding changes in the templates.
</p>
<blockquote>
<dl>
<dt>
Colors:
<strong>diff_heading</strong>,
<strong>diff_empty</strong>,
<strong>diff_remove</strong>,
<strong>diff_change</strong>,
<strong>diff_add</strong>,
and <strong>diff_dark_change</strong>
</dt>
<dd>
These options have been incorporated into the
<code>diff.ezt</code> template.
<p></p>
</dd>
<dt><strong>markup_log</strong></dt>
<dd>
This option has been incorporated into the
<code>markup.ezt</code> template.
<p></p>
</dd>
<dt>Colors: <strong>nav_header</strong>
and <strong>alt_background</strong></dt>
<dd>
These options have been incorporated into the
<code>header.ezt</code> template.
<p></p>
</dd>
<dt>
Images:
<strong>back_icon</strong>,
<strong>dir_icon</strong>,
and <strong>file_icon</strong>
</dt>
<dd>
These options have been incorporated into the
<code>directory.ezt</code>, <code>header.ezt</code>,
<code>log.ezt</code>, <code>log_table.ezt</code>, and
<code>query.ezt</code> templates.
<p></p>
</dd>
<dt><strong>use_java_script</strong>
and <strong>open_extern_window</strong></dt>
<dd>
The templates now use JavaScript in all applicable places,
and open external windows for most downloading and viewing
of files. If you wish to not use JavaScript and/or external
windows, then remove the feature(s) from the templates.
<p></p>
</dd>
<dt><strong>show_author</strong></dt>
<dd>
Changing this option would be quite strange and rare. If you
do not want to show the author for the revisions, then you
should remove it from the various templates.
<p></p>
</dd>
<dt><strong>hide_non_readable</strong></dt>
<dd>
This option was never used, so it has been removed.
<p></p>
</dd>
<dt><strong>flip_links_in_dirview</strong></dt>
<dd>
This option is no longer available. If you want the links in
your directory view flipped, then you may use the
<code>dir_alternate.ezt</code> template.
<p></p>
</dd>
</dl>
</blockquote>
<h3>Template Variables</h3>
<p>
Some template variables that were available in 0.8 have been
removed in 0.9. If you have custom templates that refer to these
variables, then you will need to modify your templates.
</p>
<blockquote>
<dl>
<dt><code>directory.ezt</code>: <var>headers</var></dt>
<dd>
The headers are now listed explicitly in the template,
rather than made available through a list.
<p></p>
</dd>
<dt>
<code>directory.ezt</code>:
<var>rows.cols</var>,
and <var>rows.span</var>
</dt>
<dd>
These variables were used in conjunction with the
<var>headers</var> variable to control the column
displays. This is now controlled explicitly within the
templates.
<p></p>
</dd>
<dt><code>directory.ezt</code>:
<var>rev_in_front</var></dt>
<dd>
This was used to indicate that revision links should
be used in the first column, rather than in their
standard place in the second column. Changing the
links should now be done in the template, rather than
according to this variable. You may want to look at
the <code>dir_alternate.ezt</code> template, which has
the revision in front.
<p></p>
</dd>
<dt><code>directory.ezt</code>:
<var>rows.attic</var>
and <var>rows.hide_attic_href</var></dt>
<dd>
These variable were used to manage the hide and
showing of the contents of the <code>Attic/</code>
subdirectory. Several new variables were introduced
which can be used to replace this functionality:
<var>show_attic_href</var>,
<var>hide_attic_href</var>, and <var>rows.state</var>.
<p></p>
</dd>
</dl>
</blockquote>
<hr>
<h2><a name="from7">Upgrading from ViewCVS 0.7 or earlier</a></h2>
<p>
This section discusses how to upgrade ViewCVS 0.7, or earlier,
to 0.8 or a later version of the software.
</p>
<p>
<strong>NOTE:</strong> these changes will bring you up to the
requirements of version 0.8. You must also follow the directions
for <a href="#from8">upgrading from 0.8</a>.
</p>
<h3>Configuration Options</h3>
<p>
The largest change from 0.7 to 0.8, that you will need to deal
with, is the introduction of templates. This shifted many
configuration file options into the templates, for more direct
editing of the output style, colors, and layout. Below is a list
of options that no longer exist, and where you can find their
counterpart in the current version of ViewCVS.
</p>
<p>
The following options have all been removed in ViewCVS 0.8. If
you made local changes to your ViewCVS configuration, then you
will need to edit templates in the <code>templates/</code>
subdirectory.
</p>
<blockquote>
<dl>
<dt>
The [text] section:
<strong>short_intro</strong>,
<strong>long_intro</strong>,
and <strong>doc_info</strong>
</dt>
<dd>
These options have been incorporated into the
<code>doc/help_rootview.html</code> page and the
<code>doc/help_dirview.html</code> page.
<p></p>
</dd>
<dt><strong>repository_info</strong></dt>
<dd>
This option is now incorporated into the
<code>directory.ezt</code> template.
<p></p>
</dd>
<dt><strong>table_padding</strong></dt>
<dd>
The table padding values can be changed in the
<code>directory.ezt</code> template.
<p></p>
</dd>
<dt><strong>table_border</strong></dt>
<dd>
Edit <code>directory.ezt</code> to add a border around the
directory table.
<p></p>
</dd>
<dt>
<strong>column_header_normal</strong> and
<strong>column_header_sorted</strong>
</dt>
<dd>
Edit <code>directory.ezt</code> to modify the colors of the
column headers.
<p></p>
</dd>
<dt>
<strong>extern_window_width</strong> and
<strong>extern_window_height</strong>
</dt>
<dd>
These options were never used and have been removed.
<p></p>
</dd>
<dt><strong>logo</strong></dt>
<dd>
Edit the templates directly (<code>directory.ezt</code>,
<code>log.ezt</code> or <code>log_table.ezt</code> and if
needed <code>query.ezt</code>) to alter the URL and size of
your logo.
<p></p>
</dd>
<dt><strong>allow_version_select</strong></dt>
<dd>
Edit the <code>log.ezt</code> template if you want to remove
the link which allows the user to select a revision for a
diff.
<p></p>
</dd>
<dt><strong>input_text_size</strong></dt>
<dd>
Edit the <code>log.ezt</code> template if you want to change
the size of the entry box for revisions for performing
diffs.
<p></p>
</dd>
<dt><strong>even_odd</strong></dt>
<dd>
Edit the <code>directory.ezt</code> and
<code>query.ezt</code> templates if you want to change the
colors of the rows in the directory and query result tables.
<p></p>
</dd>
<dt>Colors: <strong>text</strong>
and <strong>background</strong></dt>
<dd>
These options have been incorporated into the
<code>directory.ezt</code>, <code>log.ezt</code>, and
<code>log_table.ezt</code> templates.
<p></p>
</dd>
