GitHub CLI - Remote Analysis & Discovery

Remote repository operations, codebase comparison, and code discovery without cloning.

When to Use

• Analyze repositories without cloning
• Compare codebases side-by-side
• Fetch specific files from any repo
• Find trending repositories and code patterns
• Search code across GitHub

Quick Operations

Fetch a file remotely

gh api repos/OWNER/REPO/contents/path/file.ts --template '{{.content | base64decode}}'

Get directory listing

gh api repos/OWNER/REPO/contents/PATH

Search code

gh search code "pattern" --language=typescript

Find trending repos

gh search repos --language=rust --sort stars --order desc

Compare Two Codebases

Systematic workflow for comparing repositories to identify similarities and differences.

Example use: "Compare solana-fm/explorer-kit and tenequm/solana-idls"

Step 1: Fetch directory structures

gh api repos/OWNER-A/REPO-A/contents/PATH
gh api repos/OWNER-B/REPO-B/contents/PATH

If comparing a monorepo package, specify the path (e.g., packages/explorerkit-idls).

Step 2: Compare file lists

gh api repos/OWNER-A/REPO-A/contents/PATH -q '.[].name'
gh api repos/OWNER-B/REPO-B/contents/PATH -q '.[].name'

Compare the output of each command to identify files unique to each repo and common files.

Step 3: Fetch key files for comparison

Compare package dependencies:

gh api repos/OWNER-A/REPO-A/contents/package.json --template '{{.content | base64decode}}'
gh api repos/OWNER-B/REPO-B/contents/package.json --template '{{.content | base64decode}}'

Compare main entry points:

gh api repos/OWNER-A/REPO-A/contents/src/index.ts --template '{{.content | base64decode}}'
gh api repos/OWNER-B/REPO-B/contents/src/index.ts --template '{{.content | base64decode}}'

Step 4: Analyze differences

Compare the fetched files to identify:

API Surface

• What functions/classes are exported?
• Are the APIs similar or completely different?

Dependencies

• Shared dependencies (same approach)
• Different dependencies (different implementation)

Unique Features

• Features only in repo1
• Features only in repo2

For detailed comparison strategies, see references/comparison.md.

Discover Trending Content

Find trending repositories

# Most starred repos
gh search repos --sort stars --order desc --limit 20

# Trending in specific language
gh search repos --language=rust --sort stars --order desc

# Recently popular (created in last month)
gh search repos "created:>2024-10-01" --sort stars --order desc

# Trending in specific topic
gh search repos "topic:machine-learning" --sort stars --order desc

Discover popular code patterns

# Find popular implementations
gh search code "function useWallet" --language=typescript --sort indexed

# Find code in popular repos only
gh search code "implementation" "stars:>1000"

# Search specific organization
gh search code "authentication" --owner=anthropics

For complete discovery queries and patterns, see references/discovery.md.

Search Basics

Code search

# Search across all repositories
gh search code "API endpoint" --language=python

# Search in specific organization
gh search code "auth" --owner=anthropics

# Exclude results with negative qualifiers
gh search issues -- "bug report -label:wontfix"

Issue & PR search

# Find open bugs
gh search issues --label=bug --state=open

# Search assigned issues
gh search issues --assignee=@me --state=open

For advanced search syntax, see references/search.md.

Special Syntax

Field name inconsistencies

IMPORTANT: GitHub CLI uses inconsistent field names across commands:

Field	gh repo view	gh search repos
Stars	stargazerCount	stargazersCount
Forks	forkCount	forksCount

Examples:

# ✅ Correct for gh repo view
gh repo view owner/repo --json stargazerCount,forkCount

# ✅ Correct for gh search repos
gh search repos "query" --json stargazersCount,forksCount

Excluding search results

When using negative qualifiers (like -label:bug), use -- to prevent the hyphen from being interpreted as a flag:

gh search issues -- "query -label:bug"

For more syntax gotchas, see references/syntax.md.
