## プロジェクトの歴史と使われ方

loc is a Rust command-line tool for quickly counting lines of code. Its README describes it as a Rust implementation of cloc focused on speed, reporting file, line, blank, comment, and code counts by language.

### プロジェクトの歴史

The cgag/loc GitHub repository was created in July 2016. The README positions loc directly against cloc and tokei, with old benchmark examples showing loc as much faster on large source trees, while also warning readers that tokei may be smarter or more accurate for some cases.

### 採用の歴史

loc's adoption is concentrated among developers who want a fast one-shot codebase counter and are comfortable with Rust-built CLI tools. Official evidence points to GitHub interest, release binaries, cargo install, and a Homebrew package rather than a large ecosystem of integrations.

### 使われ方

By default, loc counts the current directory or a target path and prints a language table with files, total lines, blank lines, comments, and code. It is used for quick repository sizing, comparing implementation-language mix, and sanity-checking source tree growth.

### パッケージ好きにとっての重要性

loc is significant in the package-manager catalog as part of the Rust rewrite wave of classic Unix developer tools: a narrow utility, fast startup, static-ish binaries, and simple install paths through cargo or Homebrew. Its README also records the healthy package-nerd humility of pointing users at tokei when accuracy matters more than raw speed.

### タイムライン

- 2016: The cgag/loc repository is created.
- 2018: README note points users to tokei as a smarter and more accurate related Rust counter.
- 2020s: loc remains available through Homebrew and source/release installation paths.

### Related projects

- cloc is the older Perl tool that loc explicitly reimplements for speed.
- tokei is the related Rust code-counting tool that loc compares against and recommends checking for accuracy-sensitive work.
