 GLab is an open source GitLab CLI tool bringing GitLab to your terminal next to where you are already working with `git` and your code without switching between windows and browser tabs. Work with issues, merge requests, **watch running pipelines directly from your CLI** among other features.
 Inspired by [gh], the official GitHub CLI tool.
