$ scc --include-ext [py]

Exclude directories

$ scc --exclude-dir [vendor,node_modules]

Sort by lines

$ scc --sort lines

Output as JSON

Show complexity estimates

$ scc -w

Show by file

$ scc --by-file

SYNOPSIS

scc [--include-ext ext] [--exclude-dir dirs] [--format fmt] [options] [paths]

scc (Succinct Code Counter) counts lines of code in many languages. It's extremely fast, using parallelism and optimized parsing.Output shows files, lines, blanks, comments, and code per language. Wide mode adds complexity estimates based on branching.Language detection uses file extensions and content inspection. Hundreds of languages are recognized, from common to obscure.Generated and minified file detection prevents counting boilerplate. Duplicates can be ignored to avoid counting vendored code multiple times.COCOMO estimation provides rough effort metrics. These are theoretical but useful for comparisons.Output formats support integration with other tools. JSON and CSV enable processing by scripts and dashboards.

PARAMETERS

--include-ext EXT

Include only extensions.

--exclude-dir DIRS

Exclude directories.

--sort FIELD

Sort by field (files, lines, blanks, code, comments).

--format FMT

Output format (default, json, csv, html, etc.).

-w, --wide

Show complexity and weighted lines.

--by-file

Show per-file breakdown.

--no-duplicates

Ignore duplicate files.

--no-gen

Ignore generated files.

--no-min

Ignore minified files.

--cocomo

Show COCOMO estimates.

-f PATTERN

Match filenames.

-M SIZE

Max file size.

INSTALL

sudo pacman -S sc-controller

sudo apk add sc-controller

sudo zypper install sc-controller

brew install scc

nix profile install nixpkgs#sc-controller

CAVEATS

Complexity estimates are heuristic. Language detection may misidentify some files. Very large codebases may need memory.

HISTORY

scc was created by Ben Boyter around 2018 as a faster alternative to cloc and other line counters. Written in Go, it emphasizes speed through parallelism and efficient algorithms.
