š Usage
To pack your entire repository:
To pack a specific directory:
To pack specific files or directories using glob patterns:
To exclude specific files or directories:
To pack a remote repository:
To pack files from a file list (pipe via stdin):
The --stdin option allows you to pipe a list of file paths to Repomix, giving you ultimate flexibility in selecting which files to pack.
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.
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:
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:
To initialize a new configuration file (repomix.config.json):
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 š³
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):
To pack a specific directory:

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:
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:
The Markdown format structures the content in a hierarchical manner:
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:
The JSON format structures the content as a hierarchical JSON object with camelCase property names:
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

Or use a specific commit hash:
Code Compression
The --compress option utilizes Tree-sitter to perform intelligent code extraction, focusing on essential function and class signatures while removing implementation details. This can help reduce token count while retaining important structural information.
For example, this code:
Will be compressed to:
This is an experimental feature that we'll be actively improving based on user feedback and real-world usage
Token Count Optimization
Understanding your codebase's token distribution is crucial for optimizing AI interactions. Use the --token-count-tree option to visualize token usage across your project:
This displays a hierarchical view of your codebase with token counts:
You can also set a minimum token threshold to focus on larger files:
This helps you:

The configuration file supports JSON5 syntax, which allows:
Comments (both single-line and multi-line)
Trailing commas in objects and arrays
Unquoted property names
More relaxed string syntax
Schema Validation
You can enable schema validation for your configuration file by adding the $schema property:
This provides auto-completion and validation in editors that support JSON schema.
Example Configuration
Example configuration:
Global Configuration
To create a global configuration file:
The global configuration file will be created in:
Windows:
%LOCALAPPDATA%\Repomix\repomix.config.jsonmacOS/Linux:
$XDG_CONFIG_HOME/repomix/repomix.config.jsonor~/.config/repomix/repomix.config.json
Note: Local configuration (if present) takes precedence over global configuration.
Include and Ignore
Include Patterns
Repomix now supports specifying files to include using glob patterns. This allows for more flexible and powerful file selection:
Use
**/*.jsto include all JavaScript files in any directoryUse
src/**/*to include all files within thesrcdirectory and its subdirectoriesCombine multiple patterns like
["src/**/*.js", "**/*.md"]to include JavaScript files insrcand all Markdown files
Ignore Patterns
Repomix offers multiple methods to set ignore patterns for excluding specific files or directories during the packing process:
.gitignore: By default, patterns listed in your project's
.gitignorefiles and.git/info/excludeare used. This behavior can be controlled with theignore.useGitignoresetting or the--no-gitignorecli option..ignore: You can use a
.ignorefile in your project root, following the same format as.gitignore. This file is respected by tools like ripgrep and the silver searcher, reducing the need to maintain multiple ignore files. This behavior can be controlled with theignore.useDotIgnoresetting or the--no-dot-ignorecli option.Default patterns: Repomix includes a default list of commonly excluded files and directories (e.g., node_modules, .git, binary files). This feature can be controlled with the
ignore.useDefaultPatternssetting or the--no-default-patternscli option. Please see defaultIgnore.ts for more details..repomixignore: You can create a
.repomixignorefile in your project root to define Repomix-specific ignore patterns. This file follows the same format as.gitignore.Custom patterns: Additional ignore patterns can be specified using the
ignore.customPatternsoption in the configuration file. You can overwrite this setting with the-i, --ignorecommand line option.
Priority Order (from highest to lowest):
Custom patterns (
ignore.customPatterns)Ignore files (
.repomixignore,.ignore,.gitignore, and.git/info/exclude):When in nested directories, files in deeper directories have higher priority
When in the same directory, these files are merged in no particular order
Default patterns (if
ignore.useDefaultPatternsis true and--no-default-patternsis not used)
This approach allows for flexible file exclusion configuration based on your project's needs. It helps optimize the size of the generated pack file by ensuring the exclusion of security-sensitive files and large binary files, while preventing the leakage of confidential information.
Note: Binary files are not included in the packed output by default, but their paths are listed in the "Repository Structure" section of the output file. This provides a complete overview of the repository structure while keeping the packed file efficient and text-based.
Custom Instruction
The output.instructionFilePath option allows you to specify a separate file containing detailed instructions or
context about your project. This allows AI systems to understand the specific context and requirements of your project,
potentially leading to more relevant and tailored analysis or suggestions.
Here's an example of how you might use this feature:
Create a file named
repomix-instruction.mdin your project root:
In your
repomix.config.json, add theinstructionFilePathoption:
When Repomix generates the output, it will include the contents of repomix-instruction.md in a dedicated section.
Note: The instruction content is appended at the end of the output file. This placement can be particularly effective
for AI systems. For those interested in understanding why this might be beneficial, Anthropic provides some insights in
their documentation:
https://docs.anthropic.com/en/docs/build-with-claude/prompt-engineering/long-context-tips
Put long-form data at the top: Place your long documents and inputs (~20K+ tokens) near the top of your prompt, above your query, instructions, and examples. This can significantly improve Claude's performance across all models. Queries at the end can improve response quality by up to 30% in tests, especially with complex, multi-document inputs.
Comment Removal
When output.removeComments is set to true, Repomix will attempt to remove comments from supported file types. This
feature can help reduce the size of the output file and focus on the essential code content.
Supported languages include:
HTML, CSS, JavaScript, TypeScript, Vue, Svelte, Python, PHP, Ruby, C, C#, Java, Go, Rust, Swift, Kotlin, Dart, Shell,
and YAML.
Note: The comment removal process is conservative to avoid accidentally removing code. In complex cases, some comments might be retained.
š Security Check
Repomix includes a security check feature that uses Secretlint to detect potentially sensitive information in your files. This feature helps you identify possible security risks before sharing your packed repository.
The security check results will be displayed in the CLI output after the packing process is complete. If any suspicious files are detected, you'll see a list of these files along with a warning message.
Example output:
By default, Repomix's security check feature is enabled. You can disable it by setting security.enableSecurityCheck to
false in your configuration file:
Or using the --no-security-check command line option:
