Installation

• Install via Homebrew:

brew tap EranBoudjnah/cag
brew install EranBoudjnah/cag/cag

• Run via installed script:

./gradlew :cli:installDist
"./cli/build/install/cag/bin/cag" --new-feature --name=MyFeature
"./cli/build/install/cag/bin/cag" --new-view-model --name=MyViewModel

• Run via Gradle (no install):

./gradlew :cli:run --args="--new-feature --name=MyFeature"
./gradlew :cli:run --args="--new-view-model --name=MyViewModel"

Usage

Usage (canonical):

• Man page: man cag (see Manual page (optional) below for generating/installing locally)

Common examples

# Generate a new project
cag --new-project --name=MyApp --package=com.example.myapp

# Add architecture to an existing project/module
cag --new-architecture --ktlint --detekt

# Add a new feature
cag --new-feature --name=Profile --package=com.example.feature.profile

# Add a data source with Retrofit
cag --new-datasource --name=User --with=retrofit

# Add a use case
cag --new-use-case --name=FetchUser --path=architecture/domain/src/main/kotlin

# Add a ViewModel
cag --new-view-model --name=Profile

Manual page (optional)

If you prefer to use man to read your documentation, this section is for you.

# Generate man page (writes cli/build/man/cag.1)
./gradlew :cli:generateManPage

# Install to a man1 directory (may require sudo for system directories)
./gradlew :cli:installManPage

# Preview after install
man cag

Configuration (.cagrc)

You can configure library and plugin versions used by the CLI via a simple INI-style config file named .cagrc.

• Locations:

  • Project root: ./.cagrc
  • User home: ~/.cagrc

• Precedence:

  • Values in the project .cagrc override values in ~/.cagrc.

• Sections:

  • [new.versions] — applied when generating new projects (e.g., --new-project).
  • [existing.versions] — applied when generating into an existing project (e.g., new architecture, feature, data source, use case, or view model).

• Keys correspond to version keys used by the generator, for example: kotlin, androidGradlePlugin, composeBom, composeNavigation, retrofit, ktor, okhttp3, etc.

Example ~/.cagrc:

[new.versions]
kotlin=2.2.10
composeBom=2025.08.01

[existing.versions]
retrofit=2.11.0
ktor=3.0.3

Example ./.cagrc (project overrides):

[new.versions]
composeBom=2025.09.01

[existing.versions]
okhttp3=4.12.0

With the above, new projects will use composeBom=2025.09.01 (from project), kotlin=2.2.10 (from home). For operations on existing projects, retrofit=2.11.0 (home) and okhttp3=4.12.0 (project) will be applied.
