* 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.
