Summary

This PR adds support for GitLab instances, allowing users to use gh-dash with their GitLab servers via the glab CLI.

Features

  • New --gitlab <hostname> flag: Enables GitLab mode and specifies which GitLab instance to connect to
  • Provider abstraction layer: New internal/provider package that abstracts the differences between GitHub and GitLab APIs
  • GitLab provider implementation: Uses the glab CLI for all API interactions
  • MR terminology: Shows "MR/MRs" (Merge Requests) instead of "PR/PRs" when in GitLab mode
  • GitLab-specific query syntax: Supports repo:, author:, assignee:, reviewer:, label: filters
  • Label colors: Fetches and caches label colors from GitLab for proper display
  • Task commands: All actions (merge, close, reopen, etc.) use glab mr commands in GitLab mode

Usage

# Ensure glab is installed and configured
glab auth login --hostname gitlab.example.com

# Run gh-dash with GitLab
gh-dash --gitlab gitlab.example.com --config ./my-gitlab-config.yml

Configuration Example

# In GitLab mode, use 'repo:GROUP/PROJECT' in filters
prSections:
  - title: My Merge Requests
    filters: repo:mygroup/myproject author:@me
  - title: Needs My Review
    filters: repo:mygroup/myproject reviewer:@me

issuesSections:
  - title: My Issues
    filters: repo:mygroup/myproject author:@me
  - title: Assigned to Me
    filters: repo:mygroup/myproject assignee:@me

Prerequisites

  • glab CLI must be installed (installation guide)
  • glab must be authenticated with the target GitLab instance

Technical Details

  • No changes to existing GitHub functionality - all changes are additive
  • The provider pattern allows for easy addition of other Git hosting platforms in the future
  • Label colors are cached per-project to minimize API calls

Screenshots

Works the same as GitHub mode, but connects to GitLab instances

Fix issue comments not fetching - ensure syncSidebar cmd is executed
2e8e0df 
The syncSidebar() function returns a tea.Cmd that fetches issue comments
for GitLab, but this command was not being executed in several places:

- onViewedRowChanged: was overwriting cmd with PR enrich only
- TogglePreview: was not using the returned cmd at all
- Text input handlers: were not batching the sync cmd

Fixed by:
- Using tea.Batch to combine syncSidebar cmd with other cmds
- Simplified EnrichIssueComments condition (always fetch if no nodes)
@hjanuschka
Fix issue comments not showing - don't overwrite after fetching
46025fd 
The bug was that after SetIssueComments updated the issue with fetched
comments, syncSidebar() was called which re-fetched the row data from
the section (without comments) and overwrote the updated data.

Fix: Just update the sidebar content directly instead of calling
syncSidebar() after setting comments.

Also added debug logging to FetchIssueComments for troubleshooting.
