# source{d} Contributing Guidelines
source{d} projects accept contributions via GitHub pull requests.
This document outlines some of the
conventions on development workflow, commit message formatting, contact points,
and other resources to make it easier to get your contribution accepted.
## Certificate of Origin
By contributing to this project, you agree to the [Developer Certificate of
Origin (DCO)](DCO). This document was created by the Linux Kernel community and is a
simple statement that you, as a contributor, have the legal right to make the
contribution.
In order to show your agreement with the DCO you should include at the end of the commit message,
the following line: `Signed-off-by: John Doe <john.doe@example.com>`, using your real name.
This can be done easily using the [`-s`](https://github.com/git/git/blob/b2c150d3aa82f6583b9aadfecc5f8fa1c74aca09/Documentation/git-commit.txt#L154-L161) flag on the `git commit`.
If you find yourself pushed a few commits without `Signed-off-by`, you can still add it afterwards. We wrote a manual which can help: [fix-DCO.md](https://github.com/src-d/guide/blob/master/developer-community/fix-DCO.md).
## Support Channels
The official support channels, for both users and contributors, are:
- GitHub issues: each repository has its own list of issues.
- Slack: join the [source{d} Slack](https://join.slack.com/t/sourced-community/shared_invite/enQtMjc4Njk5MzEyNzM2LTFjNzY4NjEwZGEwMzRiNTM4MzRlMzQ4MmIzZjkwZmZlM2NjODUxZmJjNDI1OTcxNDAyMmZlNmFjODZlNTg0YWM) community.
*Before opening a new issue or submitting a new pull request, it's helpful to
search the project - it's likely that another user has already reported the
issue you're facing, or it's a known issue that we're already aware of.
## How to Contribute
Pull Requests (PRs) are the main and exclusive way to contribute code to source{d} projects.
In order for a PR to be accepted it needs to pass this list of requirements:
- The contribution must be correctly explained with natural language and providing a minimum working example that reproduces it.
- All PRs must be written idiomaticly:
- for Go: formatted according to [gofmt](https://golang.org/cmd/gofmt/), and without any warnings from [go lint](https://github.com/golang/lint) nor [go vet](https://golang.org/cmd/vet/)
- for other languages, similar constraints apply.
- They should in general include tests, and those shall pass.
- If the PR is a bug fix, it has to include a new unit test that fails before the patch is merged.
- If the PR is a new feature, it has to come with a suite of unit tests, that tests the new functionality.
- In any case, all the PRs have to pass the personal evaluation of at least one of the [maintainers](MAINTAINERS) of the project.
### Format of the commit message
Every commit message should describe what was changed, under which context and, if applicable, the GitHub issue it relates to:
```
plumbing: packp, Skip argument validations for unknown capabilities. Fixes #623
```
The format can be described more formally as follows:
```
<package>: <subpackage>, <what changed>. [Fixes #<issue-number>]
```

File programming language detector and toolbox to ignore binary or vendored files. *enry*, started as a port to _Go_ of the original [linguist](https://github.com/github/linguist) _Ruby_ library, that has an improved *2x performance*.

Installation
------------
The recommended way to install enry is to either [download a release](https://github.com/src-d/enry/releases) or
```
go get github.com/src-d/enry/cmd/enry
```
This project is now part of [source{d} Engine](https://sourced.tech/engine),
which provides the simplest way to get started with a single command.
Visit [sourced.tech/engine](https://sourced.tech/engine) for more information.
Examples
------------
```go
lang, safe := enry.GetLanguageByExtension("foo.go")
fmt.Println(lang, safe)
// result: Go true
lang, safe := enry.GetLanguageByContent("foo.m", []byte("<matlab-code>"))
fmt.Println(lang, safe)
// result: Matlab true
lang, safe := enry.GetLanguageByContent("bar.m", []byte("<objective-c-code>"))
fmt.Println(lang, safe)
// result: Objective-C true
// all strategies together
lang := enry.GetLanguage("foo.cpp", []byte("<cpp-code>"))
// result: C++ true
```
Note that the returned boolean value `safe` is set either to `true`, if there is only one possible language detected, or to `false` otherwise.
To get a list of possible languages for a given file, you can use the plural version of the detecting functions.
```go
langs := enry.GetLanguages("foo.h", []byte("<cpp-code>"))
// result: []string{"C", "C++", "Objective-C}
langs := enry.GetLanguagesByExtension("foo.asc", []byte("<content>"), nil)
// result: []string{"AGS Script", "AsciiDoc", "Public Key"}
langs := enry.GetLanguagesByFilename("Gemfile", []byte("<content>"), []string{})
// result: []string{"Ruby"}
```
CLI
------------
You can use enry as a command,
```bash
$ enry --help
enry v2.0.0 build: 05-08-2019_20_40_35 commit: 6ccf0b6, based on linguist commit: e456098
enry, A simple (and faster) implementation of github/linguist
usage: enry [-mode=(file|line|byte)] [-prog] <path>
enry [-mode=(file|line|byte)] [-prog] [-json] [-breakdown] <path>
enry [-mode=(file|line|byte)] [-prog] [-json] [-breakdown]
enry [-version]
```
and on repository root, it'll return an output similar to *linguist*'s output,
```bash
$ enry
97.71% Go
1.60% C
0.31% Shell
0.22% Java
0.07% Ruby
0.05% Makefile
0.04% Scala
0.01% Gnuplot
```
but not only the output; its flags are also the same as *linguist*'s ones,
```bash
$ enry --breakdown
97.71% Go
1.60% C
0.31% Shell
0.22% Java
0.07% Ruby

even the JSON flag,

"internal/tokenizer/flex/lex.linguist_yy.h",

"python/enry.c"
],
"Gnuplot": [
"benchmarks/plot-histogram.gp"
],
"Go": [
"benchmark_test.go",
```
Note that enry's CLI **_doesn't need a git repository to work_**, which is intentionally different from the linguist.
## Java bindings
Generated Java bindings using a C shared library and JNI are available under [`java`](https://github.com/src-d/enry/blob/master/java) and published on Maven at [tech.sourced:enry-java](https://mvnrepository.com/artifact/tech.sourced/enry-java) for macOS and linux.
## Python bindings
Generated Python bindings using a C shared library and cffi are not available yet and are WIP under [src-d/enry#154](https://github.com/src-d/enry/issues/154).
Divergences from linguist
------------
The `enry` library is based on the data from `github/linguist` version **v7.5.1**.
As opposed to linguist, `enry` [CLI tool](#cli) does *not* require a full Git repository in the filesystem in order to report languages.
Parsing [linguist/samples](https://github.com/github/linguist/tree/master/samples) the following `enry` results are different from linguist:
* [Heuristics for ".es" extension](https://github.com/github/linguist/blob/e761f9b013e5b61161481fcb898b59721ee40e3d/lib/linguist/heuristics.yml#L103) in JavaScript could not be parsed, due to unsupported backreference in RE2 regexp engine.
* [Heuristics for ".rno" extension](https://github.com/github/linguist/blob/3a1bd3c3d3e741a8aaec4704f782e06f5cd2a00d/lib/linguist/heuristics.yml#L365) in RUNOFF could not be parsed, due to unsupported lookahead in RE2 regexp engine.
* As of [Linguist v5.3.2](https://github.com/github/linguist/releases/tag/v5.3.2) it is using [flex-based scanner in C for tokenization](https://github.com/github/linguist/pull/3846). Enry still uses [extract_token](https://github.com/github/linguist/pull/3846/files#diff-d5179df0b71620e3fac4535cd1368d15L60) regex-based algorithm. See [#193](https://github.com/src-d/enry/issues/193).
* Bayesian classifier can't distinguish "SQL" from "PLpgSQL. See [#194](https://github.com/src-d/enry/issues/194).
* Detection of [generated files](https://github.com/github/linguist/blob/bf95666fc15e49d556f2def4d0a85338423c25f3/lib/linguist/generated.rb#L53) is not supported yet.
(Thus they are not excluded from CLI output). See [#213](https://github.com/src-d/enry/issues/213).
* XML detection strategy is not implemented. See [#192](https://github.com/src-d/enry/issues/192).
* Overriding languages and types though `.gitattributes` is not yet supported. See [#18](https://github.com/src-d/enry/issues/18).
* `enry` CLI output does NOT exclude `.gitignore`ed files and git submodules, as linguist does
In all the cases above that have an issue number - we plan to update enry to match Linguist behavior.
Benchmarks
------------
Enry's language detection has been compared with Linguist's one. In order to do that, Linguist's project directory [*linguist/samples*](https://github.com/github/linguist/tree/master/samples) was used as a set of files to run benchmarks against.
We got these results:
![histogram](benchmarks/histogram/distribution.png)
The histogram shows the number of files detected (y-axis) per time interval bucket (x-axis). As one can see, most of the files were detected faster by enry.
We found few cases where enry turns slower than linguist due to
Go regexp engine being slower than Ruby's, based on [oniguruma](https://github.com/kkos/oniguruma) library, written in C.
See [instructions](#misc) for running enry with oniguruma.
Why Enry?
------------
In the movie [My Fair Lady](https://en.wikipedia.org/wiki/My_Fair_Lady), [Professor Henry Higgins](http://www.imdb.com/character/ch0011719/?ref_=tt_cl_t2) is one of the main characters. Henry is a linguist and at the very beginning of the movie enjoys guessing the origin of people based on their accent.
"Enry Iggins" is how [Eliza Doolittle](http://www.imdb.com/character/ch0011720/?ref_=tt_cl_t1), [pronounces](https://www.youtube.com/watch?v=pwNKyTktDIE) the name of the Professor during the first half of the movie.
## Development
To build enry's CLI run:
make build
this will generate a binary in the project's root directory called `enry`.
To run the tests:
make test
### Sync with github/linguist upstream
*enry* re-uses parts of the original [github/linguist](https://github.com/github/linguist) to generate internal data structures.
In order to update to the latest release of linguist do:
```bash
$ git clone https://github.com/github/linguist.git .linguist
$ cd .linguist; git checkout <release-tag>; cd ..
# put the new release's commit sha in the generator_test.go (to re-generate .gold test fixtures)
# https://github.com/src-d/enry/blob/13d3d66d37a87f23a013246a1b0678c9ee3d524b/internal/code-generator/generator/generator_test.go#L18
$ make code-generate
```
To stay in sync, enry needs to be updated when a new release of the linguist includes changes to any of the following files:
* [languages.yml](https://github.com/github/linguist/blob/master/lib/linguist/languages.yml)
* [heuristics.yml](https://github.com/github/linguist/blob/master/lib/linguist/heuristics.yml)
* [vendor.yml](https://github.com/github/linguist/blob/master/lib/linguist/vendor.yml)
* [documentation.yml](https://github.com/github/linguist/blob/master/lib/linguist/documentation.yml)
There is no automation for detecting the changes in the linguist project, so this process above has to be done manually from time to time.
When submitting a pull request syncing up to a new release, please make sure it only contains the changes in
the generated files (in [data](https://github.com/src-d/enry/blob/master/data) subdirectory).
Separating all the necessary "manual" code changes to a different PR that includes some background description and an update to the documentation on ["divergences from linguist"](##divergences-from-linguist) is very much appreciated as it simplifies the maintenance (review/release notes/etc).
## Misc
<details>
### Benchmark
All benchmark scripts are in [*benchmarks*](https://github.com/src-d/enry/blob/master/benchmarks) directory.
#### Dependencies
As benchmarks depend on Ruby and Github-Linguist gem make sure you have:
- Ruby (e.g using [`rbenv`](https://github.com/rbenv/rbenv)), [`bundler`](https://bundler.io/) installed
- Docker
- [native dependencies](https://github.com/github/linguist/#dependencies) installed
- Build the gem `cd .linguist && bundle install && rake build_gem && cd -`
- Install it `gem install --no-rdoc --no-ri --local .linguist/github-linguist-*.gem`
#### Quick benchmark
To run quicker benchmarks you can either:
make benchmarks
to get average times for the main detection function and strategies for the whole samples set or:
make benchmarks-samples
if you want to see measures per sample file.
#### Full benchmark
If you want to reproduce the same benchmarks as reported above:
- Make sure all [dependencies](#benchmark-dependencies) are installed
- Install [gnuplot](http://gnuplot.info) (in order to plot the histogram)
- Run `ENRY_TEST_REPO="$PWD/.linguist" benchmarks/run.sh` (takes ~15h)
It will run the benchmarks for enry and linguist, parse the output, create csv files and plot the histogram.
### Faster regexp engine (optional)
[Oniguruma](https://github.com/kkos/oniguruma) is CRuby's regular expression engine.
It is very fast and performs better than the one built into Go runtime. *enry* supports swapping
between those two engines thanks to [rubex](https://github.com/moovweb/rubex) project.
The typical overall speedup from using Oniguruma is 1.5-2x. However, it requires CGo and the external shared library.
On macOS with [Homebrew](https://brew.sh/), it is:
```
brew install oniguruma
```
On Ubuntu, it is
```
sudo apt install libonig-dev
```
To build enry with Oniguruma regexps use the `oniguruma` build tag
```
go get -v -t --tags oniguruma ./...
```
and then rebuild the project.

Package enry implements multiple strategies for programming language identification.
Identification is made based on file name and file content using a seriece
of strategies to narrow down possible option.
Each strategy is available as a separate API call, as well as a main enty point
GetLanguage(filename string, content []byte) (language string)
It is a port of the https://github.com/github/linguist from Ruby.
Upstream Linguist YAML files are used to generate datastructures for data

## go-oniguruma
<a href="https://travis-ci.org/src-d/go-oniguruma"><img alt="Build Status" src="https://travis-ci.org/src-d/go-oniguruma.svg?branch=master" /></a>
This repository is a fork of [moovweb/rubex](https://github.com/moovweb/rubex/tree/go1) - a simple regular expression library (based on [oniguruma](https://github.com/kkos/oniguruma)) that supports Ruby's regex syntax.
The _rubex_ was originally created by Zhigang Chen (zhigang.chen@moovweb.com or zhigangc@gmail.com). It implements all the public functions of Go's Regexp package, except LiteralPrefix.
By the benchmark tests in regexp, the library is 40% to 10X faster than Regexp on all but one test. Unlike Go's regexp, this library supports named capture groups and also allow `"\\1"` and `"\\k<name>"` in replacement strings.
The library calls the _oniguruma_ regex library for regex pattern searching. All replacement code is done in Go.
### Install all (_oniguruma_ and _rubex_):
```sh
# linux (debian/ubuntu/...)
sudo apt-get install libonig-dev
# osx (homebrew)
brew install oniguruma
go install -i .
```

# Trie
[![GoDoc](http://godoc.org/github.com/toqueteos/trie?status.png)](http://godoc.org/github.com/toqueteos/trie)
This is a fork of https://github.com/cespare/go-trie that adds the `PrefixIndex` method.
It's required for https://github.com/toqueteos/substring.

# substring [![Build Status](https://travis-ci.org/toqueteos/substring.png?branch=master)](https://travis-ci.org/toqueteos/substring) [![GoDoc](http://godoc.org/github.com/toqueteos/substring?status.png)](http://godoc.org/github.com/toqueteos/substring) [![GitHub release](https://img.shields.io/github/release/toqueteos/substring.svg)](https://github.com/toqueteos/substring/releases)
Simple and composable alternative to [regexp](http://golang.org/pkg/regexp/) package for fast substring searches.
## Installation
The recommended way to install substring
```
go get -t gopkg.in/toqueteos/substring.v1
```
The `-t` flag is for fetching [gocheck](https://gopkg.in/check.v1), required for tests and benchmarks.
## Examples
A basic example with two matchers:
```go
package main
import (
"fmt"
"regexp"
"gopkg.in/toqueteos/substring.v1"
)
func main() {
m1 := substring.After("assets/", substring.Or(
substring.Has("jquery"),
substring.Has("angular"),
substring.Suffixes(".js", ".css", ".html"),
))
fmt.Println(m1.Match("assets/angular/foo/bar")) //Prints: true
fmt.Println(m1.Match("assets/js/file.js")) //Prints: true
fmt.Println(m1.Match("assets/style/bar.css")) //Prints: true
fmt.Println(m1.Match("assets/foo/bar.html")) //Prints: false
fmt.Println(m1.Match("assets/js/qux.json")) //Prints: false
fmt.Println(m1.Match("core/file.html")) //Prints: false
fmt.Println(m1.Match("foobar/that.jsx")) //Prints: false
m2 := substring.After("vendor/", substring.Suffixes(".css", ".js", ".less"))
fmt.Println(m2.Match("foo/vendor/bar/qux.css")) //Prints: true
fmt.Println(m2.Match("foo/var/qux.less")) //Prints: false
re := regexp.MustCompile(`vendor\/.*\.(css|js|less)$`)
fmt.Println(re.MatchString("foo/vendor/bar/qux.css")) //Prints: true
fmt.Println(re.MatchString("foo/var/qux.less")) //Prints: false
}
```
## How fast?
It may vary depending on your use case but 1~2 orders of magnitude faster than `regexp` is pretty common.
Test it out for yourself by running `go test -check.b`!
```
$ go test -check.b
