Module language 

What language a path is written in, the colour GitHub paints it, and the comment syntax the line counter needs.

Detection is a pure path function: the syntax registry already maps every extension it can highlight to a grammar, so that mapping stays the one source of truth and this module adds the languages diffler counts but does not highlight. Colours are Linguist’s own hexes, the ones a reader knows from a repository page, lifted toward the foreground when the terminal’s background would swallow them.

Structs

Language

A language diffler can name, with everything the breakdown needs about it.

Functions

count_lines

The (code, comments, blanks) a source text holds. A line counts as a comment when it opens with one, so a trailing // note after code reads as code, the same call scc and cloc make.

of_path

The language of path, by extension or by whole filename.

readable_on

Lift color until it separates from bg. Linguist’s palette is tuned for a white page, so a few entries (JSON’s #292929, C’s #555555) vanish on a dark terminal and a few of the bright ones wash out on a light one.
