Quick Start

Installation

go install github.com/EvilFreelancer/coddy-agent/cmd/coddy@latest

Or build and install manually from source:

git clone https://github.com/EvilFreelancer/coddy-agent
cd coddy-agent
make install

make install builds the binary and copies it to the appropriate location:

• root - /usr/local/bin/coddy
• regular user - ~/.local/bin/coddy

To only build without installing:

make build
# or manually:
go build -ldflags "-X github.com/EvilFreelancer/coddy-agent/internal/version.Version=$(git describe --tags --always)" -o coddy ./cmd/coddy/

Terminal UI

Run coddy in any project directory to open the interactive terminal UI:
