Module difft::parse::guess_language

Expand description

Guess which programming language a file is written in.

This is heavily based on GitHub’s linguist, particularly its languages.yml.

Difftastic does not reuse languages.yml directly. Linguist has a larger set of language detection strategies.

Structs

Language 🔒
Languages supported by difftastic. Each language here has a corresponding tree-sitter parser.
LanguageOverride 🔒

from_emacs_mode_header 🔒
Try to guess the language based on an Emacs mode comment at the beginning of the file.
from_glob 🔒
from_shebang 🔒
Try to guess the language based on a shebang present in the source.
guess 🔒
language_globs 🔒
File globs that identify languages based on the file path.
language_name 🔒
The language name shown to the user.
language_override_from_name 🔒
If there is a language called name (comparing case insensitively), return it. Treat "text" as an additional option.
looks_like_hacklang 🔒
looks_like_objc 🔒
Use a heuristic to determine if a ‘.h’ file looks like Objective-C. We look for a line starting with ‘#import’, ‘@interface’ or ‘@protocol’ near the top of the file. These keywords are not valid C or C++, so this should not produce false positives.
looks_like_xml 🔒
