* rerun snapshots with proper jest version
* pin jest-docblock to latest @test release
* comment out docs for new feature from readme
* remove leading newlines
* ensure blank line between docblock and rest of file
* remove backtick string
* Split Less and SCSS parsing into different parsers
Now, .less files are always parsed with postcss-less, and .scss files
areare always parsed with postcss-scss. This:
- Is less hacky.
- Is meant to avoid issues like #2829.
- Is probably more performant.
`parser: "postcss"` and `--parser postcss` continue to work like before:
First trying postcss-less, and if that fails, postcss-scss, unless a
regex says that we should try in the opposite order. The new values for
the parser option are "postcss-less" and "postcss-scss".
* Remove postcss from package.json since it is not used
* Rename parser-less to less and parser-scss to scss
* Deprecate parser:postcss in favor of parser:css
* Fix CSS tests
* Upgrade cosmiconfig to v3, remove hardcoded combinatoric problem
* Fix indendation change from 1.7
* Ensure default value for useCache is true
* Pin mem version
* Add option to require @prettier or @format pragma
Fixes#2397.
Inspired by `eslint-plugin-prettier` and the discussion in #2397, this
implements requiring a special comment pragma to be present in a file's
first comment in order to be formatted.
This will help large codebases gradually transition to prettier over
time without tons of churn or large code reviews.
I implemented this as a standard prettier "option", not just a typical
`argv` flag, as it is relevant in both the cli and the api. This way it
can be provided programmatically, on the command line, or standardized
in a prettierrc file so like the style options, every user can use this
setting consistently and only apply prettier to relevant files, no
mattier their editor integration.
This requires the pragma begin with `@` (in fact it's inserted if the
user doesn't provide it). Currently the usage implies it must be
"prettier" or "format", but it can technically be any value other than
"none", which is similar to the `trailingCommas` option.

* Don't quote anything in runPrettier; this is usually handled by a shell
* Make --require-pragma a boolean option
* Use jest-docblock to find pragmas without parsing the ast
* Clarify docs
* includes -> indexOf
* Move test out of integration
This fixes a warning when installing prettier from github:
warning prettier > chalk@2.0.1: Please upgrade to Chalk 2.1.0 - template literals in this version (2.0.1) are quite buggy.
* Add comments showing parser arguments
Since this is how they are invoked, the comments make it easier to maintain.
* Use babylon.parseExpression for JSON
See https://github.com/prettier/prettier/issues/2378#issuecomment-314600778
Note that this doesn't yet print comments:
echo '{/*comment*/"K":"V"}' | ./bin/prettier.js --parser json
* Remove parser-json.js
This reduces duplicate code in the built package.

This changes the eslint error formatting from:
/Users/josephfrazier/workspace/prettier/src/printer-postcss.js
3:31 error Insert `;` prettier/prettier
to:
✘ prettier/prettier Insert `;`
src/printer-postcss.js:3:31
const util = require("./util")
^
which makes them clickable in terminals like iTerm2 and Guake. See
[eslint-friendly-formatter] for details.

Before, this error happened upon `yarn build`:
🚨 (commonjs plugin) Binding arguments in strict mode (49161:16) in /Users/josephfrazier/workspace/prettier/node_modules/typescript/lib/typescript.js
* Fix support for node 4 (#1988)
* Fix website on iOS Safari (#1970)
Formatting change:
* Position JSX whitespace (`{" "}`) at the end of lines (#1964)
Lots of small fixes, mainly for TypeScript.
* Initial GraphQL implementation
This is the bare minimum amount of code to make graphql work. Turns out it's pretty easy to add support for other languages :)
* Fixing support for `graphql` parsing
There was a few structural changes with the addition of CSS and Typescript that we had to take into account.
* Fixing file glob, adding `graphql` to yarn.lock
* Removing extraneous file
* Adding `graphql` parser, style changes
* Splitting out graphql printer
* Removing merge conflict
* Fixing yarn.lock
* Addressing code review, using `createError`
* Adding release config
* Using exact version
* Removing destructuring
The hackiness continues! I'm now bundling an existing bundle again in order for it to get exported as a global variable :p There's likely a better solution, but it kind of works.
Because I have to regenerate the docs, I just tagged it as 1.4.0-beta and added typescript and postcss in there.
It turns out rollup doesn't use the same algorithm for bundling commonjs files when there are cycles as node, which breaks postcss: https://twitter.com/Rich_Harris/status/869021144191561729. Webpack works just fine with it.
This sucks to have this rollup/webpack frankenstein but I really want to be able to release and don't really want to spend yet another day or two trying to make it work well.
We use a heuristic to figure out if it's a SCSS or Less file. And if it doesn't work, we try again with the other one. We do the same for JSX and TypeScript.
Fixes#1784
I wanted to see how hard it would be to add support for CSS inside of prettier. Turns out, it's not that hard. I spent a few hours printing post-css values and getting all the stylefmt unit tests to not throw.
* Improve ESLint setup
- Uses `eslint:recommended` + a handful more rules.
- Uses .eslintignore so that editors can understand which files to lint.
- Uses .eslintrc<strong>.js</strong> so more editors get syntax highlighting.
* Fix ESLint errors
About half of them were fixed by `eslint . --fix`.
This commit updates `npm run format:all` to not only format .js files in
src/ and bin/, but also tests_config/ and scripts/, as well as all
jsfmt.spec.js files.
It also includes the result of running `npm run format:all`, except
changes to src/ and bin/.
* fix TSCallSignature
* fix TSTypeReference
* remove test with invalid syntax
* --wip--
* partially fix TSTypeReference
* get comments right for TypeScript interfaces
* Extract custom tests from tests/flow/
Approach:
1. Remove all .js files in tests/flow except .snap.js files.
2. Copy over all .js files from tests/ in the flow repo.
3. Go through the diff looking for deletions.
- It was easy to see which deletions were due to changes in the tests
due to updates in the flow repo.
- For the rest of the deletions, I used `git blame` to verify that
they had been added by us since the flow tests were copied over.
This makes tests/flow/ simply a copy of the tests from the flow repo,
making it easier to sync with the upstream flow tests in the future.
* Add a script for syncing the flow tests
* Sync the flow tests
ast-types was missing a type, I sent a PR on ast-type ( https://github.com/benjamn/ast-types/pull/211 ) which was merged and released (thanks @benjamn for being super quick!). So I'm upgrading ast-types and add the test in this PR.

This let's you run `pp(x) === pp(pp(x))` across an entire codebase quickly. I think it's small enough that we can merge it in to master while we are nailing down all the issues.
You can see the output in #610
* Validate user-provided config with jest-validate
* Don't use object shorthand
* Update jest-validate to 18.2
* Fix Node4 destructuring from require
* Make use of jest-validate for deprecation message
* Remove chalk reference

* Support the `--color` option more explicitly
* Update rollup config to handle babel-code-frame
* Use exact dependencies
It doesn't compile cleanly anymore:
- esutils checks for Buffer.isBuffer without ensuring that Buffer exists.
- for version, we require a json file, need a rollup extension for that.
I no longer hardcode the version number.
Note: we need to merge this pull request after we have done the release so that the version number is correct and need to rebuild the minified version in a subsequent commit.
The current implementation with `JSON.stringify()` is clever but unfortunately generates incorrect JavaScript. Using `jsesc` seems like a better and safer option. https://github.com/mathiasbynens/jsesc It doesn't have any dependencies and is pretty small.
I opted for escaping all the non ascii characters, so we don't display emojis anymore. I don't think that the world is ready yet for having random unicode characters inside of source files, there still are so many parts of the toolchain that breaks with them. If we want to revert back on this decision, there's a `minimal` option on jsesc which only escapes values that need to in order to generate valid JavaScript file (assuming the encoding of the file is set to utf8).
Also, while working on React Native, we've seen that there is an optimization inside of jsc for js files that are all ascii: it doesn't do a copy for the conversion to ucs16.
Fixes#163
This is a very handy way of playing out with prettier without having to install it. People have already been using it actively in the issues. Putting it directly inside of the repo would be better than on mine.
