gulp-cli

Command Line Utility for Gulp

Install

npm install --global gulp-cli

Usage

> gulp [flags] <task> <task>...

Custom Metadata

When listing tasks with the gulp -T command, gulp-cli displays some custom metadata as defined upon task functions. Currently supported properties:

• task.description - String of the description to display.

function clean() { ... }
clean.description = 'Cleans up generated files.';

• task.flags - Object with key/value pairs being flag/description to display.

function build() { ... }
build.flags = {
  '--prod': 'Builds in production mode.'
};

Example Usage:

function build() { ... }
build.description = 'Build entire project.';
build.flags = {
  '--prod': 'Builds in production mode (minification, etc).'
};
// gulp 3.x
gulp.task('build', build);
// gulp 4.x
gulp.task(build);

Tasks

The task(s) listed on the command line will be executed. If more than one task is listed, Gulp will execute all of them concurrently, that is, as if they had all been listed as dependencies of a single task.

By default, Gulp does not serialize tasks listed on the command line. If you would like to execute tasks serially, you must specify the --series flag. e.g. gulp clean build --series

Just running gulp will execute the task default. If there is no default task, gulp will error.

Completion

Thanks to the grunt team, specifically Tyler Kellen

To enable tasks auto-completion in shell you should add eval "$(gulp --completion=shell)" in your .shellrc file.

Bash:

Add eval "$(gulp --completion=bash)" to ~/.bashrc.

Zsh:

Add eval "$(gulp --completion=zsh)" to ~/.zshrc.

Powershell:

Add Invoke-Expression ((gulp --completion=powershell) -join [System.Environment]::NewLine) to $PROFILE.

Fish:

Add gulp --completion=fish | source to ~/.config/fish/config.fish.

Compilers

You can find a list of supported languages at https://github.com/js-cli/js-interpret. If you would like to add support for a new language, send pull requests/open issues on that project.

Environment

The CLI adds process.env.INIT_CWD which is the original cwd it was launched from.

Configuration

Configuration is supported through the use of a .gulp.* file (e.g. .gulp.json, .gulp.yml). You can find a list of supported languages at https://github.com/js-cli/js-interpret.

Configuration from the home directory (~) and current working directory (cwd) are merged with cwd taking precedence.

Supported configurations properties:

Flags

gulp has very few flags to know about. All other flags are for tasks to use if needed.

Some flags only work with gulp 4 and will be ignored when invoked against gulp 3.
