When using `--stdin`, the specified files are effectively added to the include patterns. This means that the normal include and ignore behavior still applies - files specified via stdin will still be excluded if they match ignore patterns. > [!NOTE] > When using `--stdin`, file paths can be relative or absolute, and Repomix will automatically handle path resolution and deduplication. To include git logs in the output: ```bash # Include git logs with default count (50 commits) repomix --include-logs # Include git logs with specific commit count repomix --include-logs --include-logs-count 10 # Combine with diffs for comprehensive git context repomix --include-logs --include-diffs ``` The git logs include commit dates, messages, and file paths for each commit, providing valuable context for AI analysis of code evolution and development patterns. To compress the output: ```bash repomix --compress # You can also use it with remote repositories: repomix --remote yamadashy/repomix --compress ``` To initialize a new configuration file (`repomix.config.json`): ```bash repomix --init ``` Once you have generated the packed file, you can use it with Generative AI tools like ChatGPT, DeepSeek, Perplexity, Gemini, Gemma, Llama, Grok, and more. ### Docker Usage 🐳 You can also run Repomix using Docker. This is useful if you want to run Repomix in an isolated environment or prefer using containers. Basic usage (current directory): ```bash docker run -v .:/app -it --rm ghcr.io/yamadashy/repomix ``` To pack a specific directory: ```bash docker run -v .:/app -it --rm ghcr.io/yamadashy/repomix path/to/directory ``` Process a remote repository and output to a `output` directory: ```bash docker run -v ./output:/app -it --rm ghcr.io/yamadashy/repomix --remote https://github.com/yamadashy/repomix ``` ### Prompt Examples Once you have generated the packed file with Repomix, you can use it with AI tools like ChatGPT, DeepSeek, Perplexity, Gemini, Gemma, Llama, Grok, and more. Here are some example prompts to get you started: #### Code Review and Refactoring For a comprehensive code review and refactoring suggestions: ``` This file contains my entire codebase. Please review the overall structure and suggest any improvements or refactoring opportunities, focusing on maintainability and scalability. ``` #### Documentation Generation To generate project documentation: ``` Based on the codebase in this file, please generate a detailed README.md that includes an overview of the project, its main features, setup instructions, and usage examples. ``` #### Test Case Generation For generating test cases: ``` Analyze the code in this file and suggest a comprehensive set of unit tests for the main functions and classes. Include edge cases and potential error scenarios. ``` #### Code Quality Assessment Evaluate code quality and adherence to best practices: ``` Review the codebase for adherence to coding best practices and industry standards.

Suggest specific changes to align the code with best practices. ``` #### Library Overview Get a high-level understanding of the library ``` This file contains the entire codebase of library. Please provide a comprehensive overview of the library, including its main purpose, key features, and overall architecture. ``` Feel free to modify these prompts based on your specific needs and the capabilities of the AI tool you're using. ### Community Discussion Check out our [community discussion](https://github.com/yamadashy/repomix/discussions/154) where users share: - Which AI tools they're using with Repomix - Effective prompts they've discovered - How Repomix has helped them - Tips and tricks for getting the most out of AI code analysis Feel free to join the discussion and share your own experiences! Your insights could help others make better use of Repomix. ### Output File Format Repomix generates a single file with clear separators between different parts of your codebase. To enhance AI comprehension, the output file begins with an AI-oriented explanation, making it easier for AI models to understand the context and structure of the packed repository. #### XML Format (default) The XML format structures the content in a hierarchical manner: ```xml This file is a merged representation of the entire codebase, combining all repository files into a single document. (Metadata and usage AI instructions) src/ cli/ cliOutput.ts index.ts (...remaining directories) // File contents here (...remaining files) (Custom instructions from `output.instructionFilePath`) ``` For those interested in the potential of XML tags in AI contexts: https://docs.anthropic.com/en/docs/build-with-claude/prompt-engineering/use-xml-tags > When your prompts involve multiple components like context, instructions, and examples, XML tags can be a > game-changer. They help Claude parse your prompts more accurately, leading to higher-quality outputs. This means that the XML output from Repomix is not just a different format, but potentially a more effective way to feed your codebase into AI systems for analysis, code review, or other tasks. #### Markdown Format To generate output in Markdown format, use the `--style markdown` option: ```bash repomix --style markdown ``` The Markdown format structures the content in a hierarchical manner: ````markdown This file is a merged representation of the entire codebase, combining all repository files into a single document. # File Summary (Metadata and usage AI instructions) # Repository Structure ``` src/ cli/ cliOutput.ts index.ts ``` (...remaining directories) # Repository Files ## File: src/index.js ``` // File contents here ``` (...remaining files) # Instruction (Custom instructions from `output.instructionFilePath`) ```` This format provides a clean, readable structure that is both human-friendly and easily parseable by AI systems. #### JSON Format To generate output in JSON format, use the `--style json` option: ```bash repomix --style json ``` The JSON format structures the content as a hierarchical JSON object with camelCase property names: ```json { "fileSummary": { "generationHeader": "This file is a merged representation of the entire codebase, combined into a single document by Repomix.", "purpose": "This file contains a packed representation of the entire repository's contents...", "fileFormat": "The content is organized as follows...", "usageGuidelines": "- This file should be treated as read-only...", "notes": "- Some files may have been excluded based on .gitignore, .ignore, and .repomixignore rules..." }, "userProvidedHeader": "Custom header text if specified", "directoryStructure": "src/\n cli/\n cliOutput.ts\n index.ts\n config/\n configLoader.ts", "files": { "src/index.js": "// File contents here", "src/utils.js": "// File contents here" }, "instruction": "Custom instructions from instructionFilePath" } ``` This format is ideal for: - **Programmatic processing**: Easy to parse and manipulate with JSON libraries - **API integration**: Direct consumption by web services and applications - **AI tool compatibility**: Structured format for machine learning and AI systems - **Data analysis**: Straightforward extraction of specific information using tools like `jq` ##### Working with JSON Output Using `jq` The JSON format makes it easy to extract specific information programmatically: ```bash # List all file paths cat repomix-output.json | jq -r '.files | keys[]' # Count total number of files cat repomix-output.json | jq '.files | keys | length' # Extract specific file content cat repomix-output.json | jq -r '.files["README.md"]' cat repomix-output.json | jq -r '.files["src/index.js"]' # Find files by extension cat repomix-output.json | jq -r '.files | keys[] | select(endswith(".ts"))' # Get files containing specific text cat repomix-output.json | jq -r '.files | to_entries[] | select(.value | contains("function")) | .key' # Extract directory structure cat repomix-output.json | jq -r '.directoryStructure' # Get file summary information cat repomix-output.json | jq '.fileSummary.purpose' cat repomix-output.json | jq -r '.fileSummary.generationHeader' # Extract user-provided header (if exists) cat repomix-output.json | jq -r '.userProvidedHeader // "No header provided"' # Create a file list with sizes cat repomix-output.json | jq -r '.files | to_entries[] | "\(.key): \(.value | length) characters"' ``` #### Plain Text Format To generate output in plain text format, use the `--style plain` option: ```bash repomix --style plain ``` ```text This file is a merged representation of the entire codebase, combining all repository files into a single document. ================================================================ File Summary ================================================================ (Metadata and usage AI instructions) ================================================================ Directory Structure ================================================================ src/ cli/ cliOutput.ts index.ts config/ configLoader.ts (...remaining directories) ================================================================ Files ================================================================ ================ File: src/index.js ================ // File contents here ================ File: src/utils.js ================ // File contents here (...remaining files) ================================================================ Instruction ================================================================ (Custom instructions from `output.instructionFilePath`) ``` ### Command Line Options #### Basic Options - `-v, --version`: Show version information and exit #### CLI Input/Output Options - `--verbose`: Enable detailed debug logging (shows file processing, token counts, and configuration details) - `--quiet`: Suppress all console output except errors (useful for scripting) - `--stdout`: Write packed output directly to stdout instead of a file (suppresses all logging) - `--stdin`: Read file paths from stdin, one per line (specified files are processed directly) - `--copy`: Copy the generated output to system clipboard after processing - `--token-count-tree [threshold]`: Show file tree with token counts; optional threshold to show only files with ≥N tokens (e.g., --token-count-tree 100) - `--top-files-len `: Number of largest files to show in summary (default: 5, e.g., --top-files-len 20) #### Repomix Output Options - `-o, --output `: Output file path (default: repomix-output.xml, use "-" for stdout) - `--style
