mix logos.format (Logos v0.2.0)

Formats Logos source files, or checks that they're already formatted. Built on Logos.Format, which formats from Ichor's raw token stream (position- and text-preserving, so comments survive) plus a simple paren-nesting-depth indentation rule -- --check-formatted mirrors mix format --check-formatted.

Usage

mix logos.format path/to/file.logos path/to/other.logos
mix logos.format "lib/**/*.logos"
mix logos.format --check-formatted path/to/file.logos

Each argument is expanded as a glob (Path.wildcard/1) -- a plain literal path (no glob metacharacters) still works, since Path.wildcard/1 returns [path] unchanged when path exists and contains no glob syntax, or [] when it doesn't exist at all (reported as an error, same as a glob matching nothing).

Without --check-formatted: every matched file is formatted via Logos.Format.format/1 and written back in place; a file already exactly formatted is left untouched (no spurious mtime bump) -- determined by comparing bytes before writing.

With --check-formatted: nothing is written. Every matched file is checked via Logos.Format.formatted?/1; if any file is not already formatted, their paths are listed and the task exits nonzero (mirrors mix format --check-formatted's own contract exactly).
