Find out what language a given file is.
This is a stripped down version of linguist
- pure language detection, nothing else ...
- no dependencies
- no Github business logic
Most languages are detected by their file extension. This is the fastest and most common situation. For script files, which are usually extensionless, we do "deep content inspection"™ and check the shebang of the file. Checking the file's contents may also be used for disambiguating languages. C, C++ and Obj-C all use
.h files. Looking for common keywords, we are usually able to guess the correct language.
LanguageSniffer.detect("lib/language_sniffer.rb").language.name #=> "Ruby" LanguageSniffer.detect("bin/language_sniffer").language.name #=> "Ruby"
