+# Contributing
+
+Hi there! We're thrilled that you'd like to contribute to this project. Your help is essential for keeping it great. The majority of contributions won't need to touch any Ruby code at all.
+
+## Adding a language
+
+We try only to add languages once they have some usage on GitHub. In most cases we prefer that languages be in use in hundreds of repositories before supporting them in Linguist.
+
+To add support for a new language:
+
+0. Add an entry for your language to [`languages.yml`][languages].
+0. Add a grammar for your language. Please only add grammars that have a license that permits redistribution.
+  0. Add your grammar as a submodule: `git submodule add https://github.com/JaneSmith/MyGrammar vendor/grammars/MyGrammar`.
+  0. Add your grammar to [`grammars.yml`][grammars] by running `script/convert-grammars --add vendor/grammars/MyGrammar`.
+0. Add samples for your language to the [samples directory][samples] in the correct subdirectory.
+0. Open a pull request, linking to a [GitHub search result](https://github.com/search?utf8=%E2%9C%93&q=extension%3Aboot+NOT+nothack&type=Code&ref=searchresults) showing in-the-wild usage.
+
+In addition, if your new language defines an extension that's already listed in [`languages.yml`][languages] (such as `.foo`) then sometimes a few more steps will need to be taken:
+
+0. Make sure that example `.foo` files are present in the [samples directory][samples] for each language that uses `.foo`.
+0. Test the performance of the Bayesian classifier with a relatively large number (1000s) of sample `.foo` files. (ping @arfon or @bkeepers to help with this) to ensure we're not misclassifying files.
+0. If the Bayesian classifier does a bad job with the sample `.foo` files then a [heuristic](https://github.com/github/linguist/blob/master/lib/linguist/heuristics.rb) may need to be written to help.
+
+Remember, the goal here is to try and avoid false positives!
+
+## Fixing a misclassified language
+
+Most languages are detected by their file extension defined in [languages.yml][languages].  For disambiguating between files with common extensions, linguist applies some [heuristics](/lib/linguist/heuristics.rb) and a [statistical classifier](lib/linguist/classifier.rb). This process can help differentiate between, for example, `.h` files which could be either C, C++, or Obj-C.
+
+Misclassifications can often be solved by either adding a new filename or extension for the language or adding more [samples][samples] to make the classifier smarter.
+
+## Fixing syntax highlighting
+
+Syntax highlighting in GitHub is performed using TextMate-compatible grammars. These are the same grammars that TextMate, Sublime Text and Atom use. Every language in [languages.yml][languages] is mapped to its corresponding TM `scope`. This scope will be used when picking up a grammar for highlighting.
+
+Assuming your code is being detected as the right language, in most cases this is due to a bug in the language grammar rather than a bug in Linguist. [`grammars.yml`][grammars] lists all the grammars we use for syntax highlighting on github.com. Find the one corresponding to your code's programming language and submit a bug report upstream. If you can, try to reproduce the highlighting problem in the text editor that the grammar is designed for (TextMate, Sublime Text, or Atom) and include that information in your bug report.
+
+You can also try to fix the bug yourself and submit a Pull Request. [TextMate's documentation](http://manual.macromates.com/en/language_grammars) offers a good introduction on how to work with TextMate-compatible grammars. You can test grammars using [Lightshow](https://github-lightshow.herokuapp.com).
+
+Once the bug has been fixed upstream, please let us know and we'll pick it up for GitHub.
+
+## Testing
+
+For development you are going to want to checkout out the source. To get it, clone the repo and run [Bundler](http://gembundler.com/) to install its dependencies.
+
+    git clone https://github.com/github/linguist.git
+    cd linguist/
+    script/bootstrap
+
+To run the tests:
+
+    bundle exec rake test
+
+Sometimes getting the tests running can be too much work, especially if you don't have much Ruby experience. It's okay: be lazy and let our build bot [Travis](http://travis-ci.org/#!/github/linguist) run the tests for you. Just open a pull request and the bot will start cranking away.
+
+Here's our current build status: [![Build Status](https://secure.travis-ci.org/github/linguist.png?branch=master)](http://travis-ci.org/github/linguist)

 # Linguist
 
-We use this library at GitHub to detect blob languages, highlight code, ignore binary files, suppress generated files in diffs, and generate language breakdown graphs.
+[issues]: https://github.com/github/linguist/issues
+[new-issue]: https://github.com/github/linguist/issues/new
 
-## Features
+This library is used on GitHub.com to detect blob languages, ignore binary or vendored files, suppress generated files in diffs, and generate language breakdown graphs.
 
-### Language detection
+See [Troubleshooting](#troubleshooting) and [`CONTRIBUTING.md`](/CONTRIBUTING.md) before filing an issue or creating a pull request.
 
-Linguist defines a list of all languages known to GitHub in a [yaml file](https://github.com/github/linguist/blob/master/lib/linguist/languages.yml). In order for a file to be highlighted, a language and a lexer must be defined there.
+## Troubleshooting
 
-Most languages are detected by their file extension. For disambiguating between files with common extensions, we first apply some common-sense heuristics to pick out obvious languages. After that, we use a
-[statistical
-classifier](https://github.com/github/linguist/blob/master/lib/linguist/classifier.rb).
-This process can help us tell the difference between, for example, `.h` files which could be either C, C++, or Obj-C.
+### My repository is detected as the wrong language
 
-```ruby
+![language stats bar](https://cloud.githubusercontent.com/assets/173/5562290/48e24654-8ddf-11e4-8fe7-735b0ce3a0d3.png)
 
-Linguist::FileBlob.new("lib/linguist.rb").language.name #=> "Ruby"
+The Language stats bar is built by aggregating the languages of each file in that repository. If it is reporting a language that you don't expect:
 
-Linguist::FileBlob.new("bin/linguist").language.name #=> "Ruby"
+0. Click on the name of the language in the stats bar to see a list of the files that are identified as that language.
+0. If you see files that you didn't write, consider moving the files into one of the [paths for vendored  code](https://github.com/github/linguist/blob/master/lib/linguist/vendor.yml), or use the [manual overrides](#overrides) feature to ignore them.
+0. If the files are being misclassified, search for [open issues][issues] to see if anyone else has already reported the issue. Any information you an add, especially links to public repositories, is helpful.
+0. If there are no reported issues of this misclassification, [open an issue][new-issue] and include a link to the repository or a sample of the code that is being misclassified.
+
+## Overrides
+
+Linguist supports a number of different custom overrides strategies for language definitions and vendored paths.
+
+### Using gitattributes
+
+Add a `.gitattributes` file to your project and use standard git-style path matchers for the files you want to override to set `linguist-documentation`, `linguist-language`, and `linguist-vendored`. `.gitattributes` will be used to determine language statistics, but will not be used to syntax highlight files. To manually set syntax highlighting, use [Vim or Emacs modelines](#using-emacs-and-vim-modelines).
+
+```
+$ cat .gitattributes
+*.rb linguist-language=Java
 ```
 
-See [lib/linguist/language.rb](https://github.com/github/linguist/blob/master/lib/linguist/language.rb) and [lib/linguist/languages.yml](https://github.com/github/linguist/blob/master/lib/linguist/languages.yml).
+Checking code you didn't write, such as JavaScript libraries, into your git repo is a common practice, but this often inflates your project's language stats and may even cause your project to be labeled as another language. By default, Linguist treats all of the paths defined in [lib/linguist/vendor.yml](https://github.com/github/linguist/blob/master/lib/linguist/vendor.yml) as vendored and therefore doesn't include them in the language statistics for a repository. Vendored files are also hidden by default in diffs on github.com.
 
-### Syntax Highlighting
+Use the `linguist-vendored` attribute to vendor or un-vendor paths.
 
-The actual syntax highlighting is handled by our Pygments wrapper, [pygments.rb](https://github.com/tmm1/pygments.rb). It also provides a [Lexer abstraction](https://github.com/tmm1/pygments.rb/blob/master/lib/pygments/lexer.rb) that determines which highlighter should be used on a file.
-
-### Stats
-
-The Language stats bar that you see on every repository is built by aggregating the languages of each file in that repository. The top language in the graph determines the project's primary language.
-
-The repository stats API, accessed through `#languages`, can be used on a directory:
-
-```ruby
-project = Linguist::Repository.from_directory(".")
-project.language.name  #=> "Ruby"
-project.languages      #=> { "Ruby" => 0.98, "Shell" => 0.02 }
+```
+$ cat .gitattributes
+special-vendored-path/* linguist-vendored
+jquery.js linguist-vendored=false
 ```
 
-These stats are also printed out by the `linguist` binary. You can use the
+Similar to vendored files, Linguist excludes documentation files from your project's language stats. (Unlike vendored files, documentation files are displayed in diffs on github.com.) [lib/linguist/documentation.yml](lib/linguist/documentation.yml) lists common documentation paths and excludes them from the language statistics for your repository.
+
+Use the `linguist-documentation` attribute to mark or unmark paths as documentation.
+
+```
+$ cat .gitattributes
+project-docs/* linguist-documentation
+docs/formatter.rb linguist-documentation=false
+```
+
+### Using Emacs and Vim modelines
+
+Alternatively, you can use Vim and Emacs style modelines to set the language for a single file. Modelines can be placed anywhere within a file and are respected when determining how to syntax-highlight a file on GitHub.com
+
+```
+Vim
+vim: set filetype=prolog:
+vim: set ft=cpp:
+
+Emacs
+-*- mode: php;-*-
+```
+
+## Usage
+
+Install the gem:
+
+```
+$ gem install github-linguist
+```
+
+Then use it in your application:
+
+```ruby
+require 'rugged'
+require 'linguist'
+
+repo = Rugged::Repository.new('.')
+project = Linguist::Repository.new(repo, repo.head.target_id)
+project.language       #=> "Ruby"
+project.languages      #=> { "Ruby" => 119387 }
+```
+
+These stats are also printed out by the `linguist` executable. You can use the
 `--breakdown` flag, and the binary will also output the breakdown of files by language.
 
-You can try running `linguist` on the `lib/` directory in this repository itself:

-#### Ignore vendored files
-
-Checking other code into your git repo is a common practice. But this often inflates your project's language stats and may even cause your project to be labeled as another language. We are able to identify some of these files and directories and exclude them.

-#### Generated file detection
-
-Not all plain text files are true source files. Generated files like minified js and compiled CoffeeScript can be detected and excluded from language stats. As an extra bonus, these files are suppressed in diffs.
-
-```ruby
-Linguist::FileBlob.new("underscore.min.js").generated? # => true
+Ruby:
+Gemfile
+Rakefile
+bin/linguist
+github-linguist.gemspec
+lib/linguist.rb
+…
 ```
 
-See [Linguist::Generated#generated?](https://github.com/github/linguist/blob/master/lib/linguist/generated.rb).
-
-## Installation
-
-github.com is usually running the latest version of the `github-linguist` gem that is released on [RubyGems.org](http://rubygems.org/gems/github-linguist).
-
-But for development you are going to want to checkout out the source. To get it, clone the repo and run [Bundler](http://gembundler.com/) to install its dependencies.
-
-    git clone https://github.com/github/linguist.git
-    cd linguist/
-    bundle install
-
-To run the tests:
-
-    bundle exec rake test
-
 ## Contributing
 
-The majority of contributions won't need to touch any Ruby code at all. The [master language list](https://github.com/github/linguist/blob/master/lib/linguist/languages.yml) is just a YAML configuration file.
+Please check out our [contributing guidelines](CONTRIBUTING.md).
 
-We try to only add languages once they have some usage on GitHub, so please note in-the-wild usage examples in your pull request.
-
-Almost all bug fixes or new language additions should come with some additional code samples. Just drop them under [`samples/`](https://github.com/github/linguist/tree/master/samples) in the correct subdirectory and our test suite will automatically test them. In most cases you shouldn't need to add any new assertions.
-
-To update the `samples.json` after adding new files to [`samples/`](https://github.com/github/linguist/tree/master/samples):
-
-    bundle exec rake samples
-
-### A note on language extensions
-
-Linguist has a number of methods available to it for identifying the language of a particular file. The initial lookup is based upon the extension of the file, possible file extensions are defined in an array called `extensions`. Take a look at this example for example for `Perl`:
-
-```
-Perl:
-  type: programming
-  ace_mode: perl
-  color: "#0298c3"
-  extensions:
-  - .pl
-  - .PL
-  - .perl
-  - .ph
-  - .plx
-  - .pm
-  - .pod
-  - .psgi
-  interpreters:
-  - perl
-```
-Any of the extensions defined are valid but the first in this array should be the most popular.
-
-### Testing
-
-Sometimes getting the tests running can be too much work, especially if you don't have much Ruby experience. It's okay: be lazy and let our build bot [Travis](http://travis-ci.org/#!/github/linguist) run the tests for you. Just open a pull request and the bot will start cranking away.
-
-Here's our current build status, which is hopefully green: [![Build Status](https://secure.travis-ci.org/github/linguist.png?branch=master)](http://travis-ci.org/github/linguist)
-
-### Releasing
-
-If you are the current maintainer of this gem:
-
- 0. Create a branch for the release: `git checkout -b cut-release-vxx.xx.xx`
- 0. Make sure your local dependencies are up to date: `bundle install`
- 0. Ensure that samples are updated: `bundle exec rake samples`
- 0. Ensure that tests are green: `bundle exec rake test`
- 0. Bump gem version in `lib/linguist/version.rb`.  For example, [like this](https://github.com/github/linguist/commit/8d2ea90a5ba3b2fe6e1508b7155aa4632eea2985).
- 0. Make a PR to github/linguist.  For example, [#1238](https://github.com/github/linguist/pull/1238).
- 0. Build a local gem: `gem build github-linguist.gemspec`
- 0. Testing:
-   0. Bump the Gemfile and Gemfile.lock versions for an app which relies on this gem
-   0. Install the new gem locally
-   0. Test behavior locally, branch deploy, whatever needs to happen
- 0. Merge github/linguist PR
- 0. Tag and push: `git tag vx.xx.xx; git push --tags`
- 0. Push to rubygems.org -- `gem push github-linguist-3.0.0.gem`

-<h1>
-Effective ATS: Dining Philosophers
-</h1>
-
-In this article, I present an implementation of a slight variant of the
-famous problem of 5-Dining-Philosophers by Dijkstra that makes simple but
-convincing use of linear types.
-
-<h2>
-The Original Problem 
-</h2>
-
-There are five philosophers sitting around a table and there are also 5
-forks placed on the table such that each fork is located between the left
-hand of a philosopher and the right hand of another philosopher. Each
-philosopher does the following routine repeatedly: thinking and dining.  In
-order to dine, a philosopher needs to first acquire two forks: one located
-on his left-hand side and the other on his right-hand side. After
-finishing dining, a philosopher puts the two acquired forks onto the table:
-one on his left-hand side and the other on his right-hand side.
-
-<h2>
-A Variant of the Original Problem 
-</h2>
-
-The following twist is added to the original version:
-
-<p>
-
-After a fork is used, it becomes a "dirty" fork and needs to be put in a
-tray for dirty forks. There is a cleaner who cleans dirty forks and then
-puts them back on the table.
-
-<h2>
-Channels for Communication
-</h2>
-
-A channel is just a shared queue of fixed capacity. The following two
-functions are for inserting an element into and taking an element out of a
-given channel:
-
-<pre
-class="patsyntax">
-#pats2xhtml_sats("\
-fun{a:vt0p} channel_insert (channel (a), a): void
-fun{a:vt0p} channel_takeout (chan: channel (a)): (a) 
-")</pre>
-
-If [channel_insert] is called on a channel that is full, then the caller is
-blocked until an element is taken out of the channel.  If [channel_takeout]
-is called on a channel that is empty, then the caller is blocked until an
-element is inserted into the channel.
-
-<h2>
-A Channel for Each Fork
-</h2>
-
-Forks are resources given a linear type. Each fork is initially stored in a
-channel, which can be obtained by calling the following function:
-
-<pre
-class="patsyntax">
-#pats2xhtml_sats("\
-fun fork_changet (n: nphil): channel(fork)
-")</pre>
-
-where the type [nphil] is defined to be [natLt(5)] (for natural numbers
-less than 5). The channels for storing forks are chosen to be of capacity
-2. The reason that channels of capacity 2 are chosen to store at most one
-element (in each of them) is to guarantee that these channels can never be
-full (so that there is no attempt made to send signals to awake callers
-supposedly being blocked due to channels being full).
-
-
-<h2>
-A Channel for the Fork Tray
-</h2>
-
-A tray for storing "dirty" forks is also a channel, which can be obtained
-by calling the following function:
-
-<pre
-class="patsyntax">
-#pats2xhtml_sats("\
-fun forktray_changet ((*void*)): channel(fork)
-")</pre>
-
-The capacity chosen for the channel is 6 (instead of 5) so that it can
-never become full (as there are only 5 forks in total).
-
-<h2>
-Philosopher Loop
-</h2>
-
-Each philosopher is implemented as a loop:
-
-<pre
-class="patsyntax">
-#pats2xhtml_dats('\
-implement
-phil_loop (n) = let
-//
-val () = phil_think (n)
-//
-val nl = phil_left (n) // = n
-val nr = phil_right (n) // = (n+1) % 5
-//
-val ch_lfork = fork_changet (nl)
-val ch_rfork = fork_changet (nr)
-//
-val lf = channel_takeout (ch_lfork)
-val () = println! ("phil_loop(", n, ") picks left fork")
-//
-val () = randsleep (2) // sleep up to 2 seconds
-//
-val rf = channel_takeout (ch_rfork)
-val () = println! ("phil_loop(", n, ") picks right fork")
-//
-val () = phil_dine (n, lf, rf)
-//
-val ch_forktray = forktray_changet ()
-val () = channel_insert (ch_forktray, lf) // left fork to dirty tray
-val () = channel_insert (ch_forktray, rf) // right fork to dirty tray
-//
-in
-  phil_loop (n)
-end // end of [phil_loop]
-')</pre>
-
-It should be straighforward to follow the code for [phil_loop].
-
-<h2>
-Fork Cleaner Loop
-</h2>
-
-A cleaner is implemented as a loop:
-
-<pre
-class="patsyntax">
-#pats2xhtml_dats('\
-implement
-cleaner_loop () = let
-//

-val () = cleaner_return (f0) // puts back cleaned [f0]
-//
-in
-  cleaner_loop ()

-')</pre>
-
-The function [cleaner_return] first finds out the number of a given fork
-and then uses the number to locate the channel for storing the fork. Its
-actual implementation is given as follows:
-
-<pre
-class="patsyntax">
-#pats2xhtml_dats('\
-implement
-cleaner_return (f) =
-{
-  val n = fork_get_num (f)
-  val ch = fork_changet (n)
-  val () = channel_insert (ch, f)
-}
-')</pre>
-
-It should now be straighforward to follow the code for [cleaner_loop].
-
-<h2>
-Testing
-</h2>
-
-The entire code of this implementation is stored in the following files:
-
-<pre>
-DiningPhil2.sats
-DiningPhil2.dats
-DiningPhil2_fork.dats
-DiningPhil2_thread.dats
-</pre>
-
-There is also a Makefile available for compiling the ATS source code into
-an excutable for testing. One should be able to encounter a deadlock after
-running the simulation for a while.
