Motivation

I needed a subject to play with Go. Writing a CLI tool is fun - especially with Cobra - and I wanted to explore how to distribute it using GitHub Actions (and GoReleaser).

Also, I get sometimes frustrated by Blade and wanted to focus on providing:

• Better performances (cf. benchmarks)
• Better support for Maven
• Shorter commands
• More consistent commands names and ordering
• Details after any command execution
• Shell completion

I'm not the only one motivated to help Liferay developpers with new dev tools. If you're looking for something to help you with Client Extensions development, definitely checkout this tool: https://github.com/bnheise/ce-cli

Installation

For macOS or Linux, you can install it using Homebrew:

brew tap lgdd/homebrew-tap
brew install liferay-cli

Checkout the release page to download the binary for your distribution.

Completions

Usage:

lfr completion [bash|zsh|fish|powershell]

To load completions for Bash, Zsh, fish and PowerShell:

Bash:

source <(lfr completion bash)
# To load completions for each session, execute once:
# Linux:
lfr completion bash > /etc/bash_completion.d/lfr
# macOS:
lfr completion bash > /usr/local/etc/bash_completion.d/lfr

Zsh:

# If shell completion is not already enabled in your environment,
# you will need to enable it.  You can execute the following once:

echo "autoload -U compinit; compinit" >> ~/.zshrc

# To load completions for each session, execute once:
lfr completion zsh > "${fpath[1]}/_lfr"

# You will need to start a new shell for this setup to take effect.

fish:

lfr completion fish | source

# To load completions for each session, execute once:
lfr completion fish > ~/.config/fish/completions/lfr.fish

PowerShell:

PS> lfr completion powershell | Out-String | Invoke-Expression

# To load completions for every new session, run:
PS> lfr completion powershell > lfr.ps1
# and source this file from your PowerShell profile.

Usage

diagnose

Run a diagnosis to verify your environment for Liferay development:

lfr diag

Aliases:
  diagnose, diag

The output of this command will list your installations of Java, Blade and Docker. It will also display how much space are being used by cached bundles and docker images.

Example:

create

workspace

lfr create workspace liferay-workspace

Aliases:
  workspace, ws

Flags:
  -b, --build string     build tool (gradle or maven) (default "gradle")

The keyword exit can be safely used with this shell as it will disconnect instead of stopping the OSGi container. Ctrl+C also disconnect from the shell.

Known issue: The "shell" command is very slow to connect
