Module difft::parse::guess_language

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.

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.
