# 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

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

### Get directory listing

```bash
gh api repos/OWNER/REPO/contents/PATH
```

### Search code

```bash
gh search code "pattern" --language=typescript
```

### Find trending repos

```bash
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

```bash
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

```bash
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:

```bash
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:

```bash
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](references/comparison.md).

## Discover Trending Content

### Find trending repositories

```bash
# 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

```bash
# Find popular implementations (code search has no sorting - scope with filters)
gh search code "function useWallet" --language=typescript

# Scope to a known repo (code search can't filter by stars - stars:>N is literal text)
gh search code "implementation" --repo=honojs/hono

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

For complete discovery queries and patterns, see [references/discovery.md](references/discovery.md).

## Search Basics

### Code search

```bash
# 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

```bash
# 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](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:**

```bash
# ✅ 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:

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

For more syntax gotchas, see [references/syntax.md](references/syntax.md).
