Create Pull Requests

Use Gemini to draft a PR title & body and open a GitHub pull request:

gmc pr              # opens a ready-for-review PR
gmc pr --draft      # create as draft
gmc pr --dry-run    # preview without pushing

You can combine --yes -q, --show-diff, --language, --baseurl, and other flags just like the commit command.

Advanced Usage & Customization

Commit Message Customization Flags

# Preview commit without making changes
gmc --dry-run

# Display the diff before committing
gmc --show-diff

# Set maximum commit message length (default: 72 characters)
gmc --max-length 50

# Generate commit messages in different languages

# Push committed changes to remote repository
gmc --push

# Use custom API endpoint
gmc --baseurl https://your-proxy.example.com

# Use specific Gemini model

Auto Issue Detection

geminicommit automatically detects issue numbers from branch names using common patterns:

feature-123-description → references issue #123
fix-456-bug → references issue #456
#789-feature → references issue #789
issue-101 → references issue #101

Combining Options

# Comprehensive example: dry run with diff, custom length, and language
gmc --dry-run --show-diff --max-length 60 --language spanish

# Production workflow: commit and push with issue reference
gmc --issue "#123" --push --no-verify

# Using custom endpoint with specific model
gmc --baseurl https://your-proxy.example.com --model gemini-2.5-pro
