|

_enry_ is also a Go library for guessing a programming language that exposes API through FFI to multiple programming environments.
|
||||
|
||||

|

applied progressively to narrow down the possible options. Each *strategy* varies on the type
|
||||
_enry_ guesses a programming language using a sequence of matching _strategies_ that are
|
||||
applied progressively to narrow down the possible options. Each _strategy_ varies on the type
|
||||
of input data that it needs to make a decision: file name, extension, the first line of the file, the full content of the file, etc.
|
||||
|
||||
Depending on available input data, enry API can be roughly divided into the next categories or use cases.
|
||||
|
||||
### By filename
|
||||
Next functions require only a name of the file to make a guess:
|
||||
- `GetLanguageByExtension` uses only file extension (wich may be ambiguous)
|
||||
- `GetLanguageByFilename` useful for cases like `.gitignore`, `.bashrc`, etc
|
||||
- all [filtering helpers](#filtering)
|
||||
|
||||
Please note that such guesses are expected not to be very accurate.

|

- all [filtering helpers](#filtering)
|
||||
|
||||
Please note that such guesses are expected not to be very accurate.
|
||||
|
||||
### By text
|
||||
|
||||
To make a guess only based on the content of the file or a text snippet, use
|
||||
- `GetLanguageByShebang` reads only the first line of text to identify the [shebang](https://en.wikipedia.org/wiki/Shebang_(Unix)).
|
||||
- `GetLanguageByModeline` for cases when Vim/Emacs modeline e.g. `/* vim: set ft=cpp: */` may be present at a head or a tail of the text.
|
||||
- `GetLanguageByClassifier` uses a Bayesian classifier trained on all the `./samples/` from Linguist.
|
||||
|
||||
- `GetLanguageByShebang` reads only the first line of text to identify the [shebang](<https://en.wikipedia.org/wiki/Shebang_(Unix)>).
|
||||
- `GetLanguageByModeline` for cases when Vim/Emacs modeline e.g. `/* vim: set ft=cpp: */` may be present at a head or a tail of the text.
|
||||
- `GetLanguageByClassifier` uses a Bayesian classifier trained on all the `./samples/` from Linguist.
|
||||
|
||||
It usually is a last-resort strategy that is used to disambiguate the guess of the previous strategies, and thus it requires a list of "candidate" guesses. One can provide a list of all known languages - keys from the `data.LanguagesLogProbabilities` as possible candidates if more intelligent hypotheses are not available, at the price of possibly suboptimal accuracy.
|
||||
|
||||
### By file
|
||||
|
||||
The most accurate guess would be one when both, the file name and the content are available:
|
||||
- `GetLanguagesByContent` only uses file extension and a set of regexp-based content heuristics.
|
||||
- `GetLanguages` uses the full set of matching strategies and is expected to be most accurate.

||||
|
||||
- `GetLanguagesByContent` only uses file extension and a set of regexp-based content heuristics.
|
||||
- `GetLanguages` uses the full set of matching strategies and is expected to be most accurate.
|
||||
|
||||
### Filtering: vendoring, binaries, etc
|
||||
*enry* expose a set of file-level helpers `Is*` to simplify filtering out the files that are less interesting for the purpose of source code analysis:
|
||||
- `IsBinary`
|
||||
- `IsVendor`
|
||||
- `IsConfiguration`
|
||||
- `IsDocumentation`
|
||||
- `IsDotFile`
|
||||
- `IsImage`

|
||||
- `GetColor`
|
||||
- `GetLanguageGroup` can be used to group similar languages together e.g. for `Less` this function will return `CSS`

## Divergences from Linguist
|

The `enry` library is based on the data from `github/linguist` version **v7.9.0**.

- 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 -`

- Make sure all [dependencies](#benchmark-dependencies) are installed
|

# substring [](https://travis-ci.org/toqueteos/substring) [](http://godoc.org/github.com/toqueteos/substring) [](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

||||
