Install

capcom is a single binary with no runtime dependencies. It runs inside a git repository, so git must be installed too. Pick whichever channel suits your platform.

Homebrew (macOS, Linux)

brew install airiclenz/tap/capcom

brew upgrade capcom picks up later releases.

Scoop (Windows)

scoop bucket add airiclenz https://github.com/airiclenz/scoop-bucket
scoop install capcom

scoop update capcom picks up later releases.

winget (Windows)

winget install AiricLenz.Capcom

winget upgrade AiricLenz.Capcom picks up later releases.

From source with Go

With Go 1.25 or later:

go install github.com/airiclenz/capcom/cmd/capcom@latest

The binary lands in $(go env GOPATH)/bin (or $GOBIN when it is set); make sure that directory is on your PATH.

Release archives

Every GitHub release carries prebuilt archives for Linux, macOS and Windows on amd64 and arm64:

capcom_<version>_<os>_<arch>.tar.gz for Linux and macOS
capcom_<version>_<os>_<arch>.zip for Windows

Each archive holds one directory, capcom_<version>_<os>_<arch>/, with the capcom binary (capcom.exe on Windows), LICENSE and README.md. The release’s SHA256SUMS file lists the checksum of every archive; check yours before unpacking, from the directory holding both files:

grep capcom_<version>_linux_amd64.tar.gz SHA256SUMS | sha256sum -c -
# on macOS:
grep capcom_<version>_darwin_arm64.tar.gz SHA256SUMS | shasum -a 256 -c -

On Windows, Get-FileHash <archive> in PowerShell prints the hash to compare with the line in SHA256SUMS.

Then copy the binary into a directory on your PATH.

Check the install

capcom version

It prints capcom followed by the version number of the binary you installed. capcom --help lists every command, and capcom <command> --help a command’s flags and examples.

A shorter command

If capcom is too long to type, a shell alias such as alias cc=capcom works well. Don’t install a binary or symlink named cc, though: that name belongs to the system C compiler, and build tools call it.

The quick start sets capcom up in a repository and walks through one Issue from creation to close.
