Fetching PR Comments

Overview

Retrieve and parse GitHub PR review comments for the current branch using gh CLI.

Quick Reference

Task	Command
Check if PR exists	gh pr view
View PR with issue comments	gh pr view --comments
Fetch review comments (code-level)	gh api repos/{owner}/{repo}/pulls/{n}/comments
Extract key fields	--jq '.[] | {path, line, body}'

Workflow

1. Get PR number for current branch:

   gh pr view --json number --jq '.number'
   

2. Fetch review comments:

   gh api repos/{owner}/{repo}/pulls/{n}/comments \
     --jq '.[] | {path: .path, line: .line, body: .body}'
   

3. Full command (single step):

   gh api repos/OWNER/REPO/pulls/$(gh pr view --json number -q .number)/comments \
     --jq '.[] | {path: .path, line: .line, body: .body}'
   

Important Distinctions

Type	What it shows	How to get
Issue comments	PR-level discussion	gh pr view --comments
Review comments	Code-level feedback	gh api .../pulls/{n}/comments

Common Patterns

Check if current branch has a PR:

gh pr view 2>/dev/null && echo "PR exists" || echo "No PR"

Get PR details + comments in one view:

gh pr view --comments

Fetch specific PR by number:

gh pr view 429 --repo owner/repo --comments

When NOT to Use

• Creating new PRs (use gh pr create)
