Gh Search Repos

GitHub CLI: Search Repositories

Overview

Search for repositories across GitHub using gh search repos. Filter by stars, forks, language, topics, license, and more.

When to Use This Skill

Use this skill when searching for repositories across GitHub:

• Finding repositories by popularity (stars/forks)
• Searching by programming language or topics
• Finding repos with good first issues
• Filtering by license or archived status
• Searching in specific organizations or by owner
• Need to exclude certain results (requires -- flag)

Syntax

gh search repos [] [flags]

Key Flags Reference

Repository Attributes

| Flag | Purpose | Example | |------|---------|---------| | --language | Programming language | --language python | | --topic | Repository topics | --topic machine-learning | | --license | License type | --license mit | | --archived {true\|false} | Archived state | --archived false | | --owner | Repository owner | --owner github | | --visibility | Visibility: public, private, internal | --visibility public |

Popularity Metrics

| Flag | Purpose | Example | |------|---------|---------| | --stars | Star count | --stars ">1000" | | --forks | Fork count | --forks ">100" | | --followers | Follower count | --followers ">50" | | --size | Size in KB | --size "100..1000" |

Issue Counts

| Flag | Purpose | Example | |------|---------|---------| | --good-first-issues | "Good first issue" label count | --good-first-issues ">=5" | | --help-wanted-issues | "Help wanted" label count | --help-wanted-issues ">=3" |

Date Filters

| Flag | Purpose | Example | |------|---------|---------| | --created | Creation date | --created ">2024-01-01" | | --updated | Last update date | --updated ">2024-06-01" |

Search Scope

| Flag | Purpose | Example | |------|---------|---------| | --match | Search in: name, description, readme | --match name | | --include-forks {false\|true\|only} | Include/exclude forks | --include-forks false |

Output & Sorting

| Flag | Purpose | Example | |------|---------|---------| | -L, --limit | Max results (default: 30) | --limit 100 | | --sort | Sort by: stars, forks, updated, etc. | --sort stars | | --order | Sort direction: asc or desc | --order desc | | --json | JSON output | --json name,stargazersCount,language | | -w, --web | Open in browser | -w |

JSON Output Fields

createdAt, defaultBranch, description, forksCount, fullName, hasDownloads, hasIssues, hasPages, hasProjects, hasWiki, homepage, id, isArchived, isDisabled, isFork, isPrivate, language, license, name, openIssuesCount, owner, pushedAt, size, stargazersCount, updatedAt, url, visibility, watchersCount

Exclusion Syntax (Critical!)

When using inline query exclusions (negations with -), you MUST use the -- separator:

✅ Correct: gh search repos -- "search-terms -qualifier:value" ❌ Wrong: gh search repos "search-terms" --flag=-value ❌ Wrong: gh search repos "search-terms" --flag=!value ❌ Wrong: gh search repos --language=-Go

Examples:

• gh search repos -- "cli -language:go" (exclude language)
• gh search repos -- "starter -archived:true" (exclude archived)
• gh search repos -- "web -topic:deprecated" (exclude topic)
• gh search repos -- "library -license:gpl-3.0" (exclude license)

Why the -- separator is required: The -- tells the shell to stop parsing flags and treat everything after it as arguments. Without it, -qualifier:value inside quotes may be misinterpreted.

Critical Syntax Rules

When to Use Flag Syntax vs Query Syntax

Decision Tree:

Does your search include:
  - Any exclusions (NOT, minus, without, except)?  → Use Query Syntax with `--`
  - Complex boolean logic (OR, AND)?              → Use Query Syntax with `--`

Otherwise:
  - Simple positive filters only?                  → Use Flag Syntax

Flag Syntax (for positive filters):

gh search repos "cli" --language go --stars ">100"

Query Syntax with -- (required for exclusions):

gh search repos -- "cli -language:javascript -archived:true"

⚠️ NEVER mix both syntaxes in a single command!

1. Exclusions and Negations

CRITICAL: When excluding results, you MUST use query syntax with the -- separator.

Exclusion Syntax Rules:

1. Use the -- separator before your query
2. Use -qualifier:value format (dash prefix for negation)
3. Quote the entire query string

Examples:

Single exclusion:

# Exclude specific language
gh search repos -- "web framework -language:javascript"

# Exclude archived repos
gh search repos -- "cli tool -archived:true"

Multiple exclusions:

# Exclude multiple languages
gh search repos -- "game engine -language:javascript -language:python"

# Exclude archived and small repos
gh search repos -- "starter -archived:true -stars:1000"

Ranges use quotes:

gh search repos "cli" --stars "100..500"

Common Use Cases

Find popular Python repos:

gh search repos "data science" --language python --stars ">5000"

Find repos with good first issues:

gh search repos --language javascript --good-first-issues ">=10"

Find recently updated repos:

gh search repos "react" --updated ">2024-01-01" --stars ">100"

Find repos by topic:

gh search repos --topic machine-learning --language python

Find repos by license:

gh search repos "web framework" --license mit,apache-2.0

Exclude archived repos:

gh search repos "cli tool" --archived false

Find repos by organization:

gh search repos --owner microsoft --visibility public

Exclude forks:

gh search repos "starter" --include-forks false

Find only forks:

gh search repos "template" --include-forks only

Find repos in star range:

gh search repos "game engine" --stars "100..1000"

Exclude specific language:

gh search repos -- "cli -language:go"

Search in name only:

gh search repos "awesome" --match name

Common Mistakes

| Mistake | Problem | Fix | |---------|---------|-----| | --language="NOT javascript" or --archived=-true | Flag syntax doesn't support negation | Use query: -- "-language:javascript" or -- "-archived:true" | | gh search repos cli -language:js | -language interpreted as flag | Use --: -- "cli -language:js" | | "cli NOT language:js" | NOT keyword doesn't work | Use -: -- "cli -language:js" | | Mixing syntaxes: --stars ">100" "cli -language:js" | Can't mix flags with query qualifiers | Use query for all: -- "cli stars:>100 -language:js" | | Not quoting comparisons | Shell interprets > | Quote: --stars ">1000" | | --archived archived | Invalid value | Use boolean: --archived true or false | | Not quoting multi-word search | Searches separately | Quote: "machine learning" | | Using @ with owner | Invalid syntax | Drop @: --owner github | | PowerShell without --% | Breaks with exclusions | Add: gh --% |
