Pew

Pew is a simple, lightweight CLI for dumping source code or directories into a single file, makes it easier to work with LLMs.

Claude Code and Sonnet 3.7 its amazing at coding, but it lacks intelligence. So the best workflow is dump your code to Grok, asking grok to prompt claude first, create a PLAN.md, and let your fellow claude to follow it

WHAT THIS CLI CAN DO

• Convert source code files to well-formatted Markdown
• Automatically detect and skip binary files
• Tree-style directory structure visualization
• GitIgnore-style pattern matching via .pewc configuration file
• Auto ignore the binary files
• Smart file extension detection for proper syntax highlighting

imgae below its how the out put files looks like

Installation

Using Homebrew

brew tap yuann3/pew
brew install pew

Linux

# Download and install in one command
curl -L https://raw.githubusercontent.com/yuann3/pew/main/install.sh | bash

Usage

pew [flags] [files...]

Flags:
-d <directory>       Directory to dump (mutually exclusive with specifying files)
-o <filename>        Output Markdown file (default: "source.md")
-h                   Show this help message
--no-default-ignores Disable default ignore patterns for directories

Examples

Dump specific files:

pew file1.go file2.go -o output.md

Dump a directory with default ignores:

pew -d /path/to/project -o project.md

Dump a directory without default ignores:

pew -d /path/to/project --no-default-ignores -o project.md

Configuration with .pewc file

Create a .pewc file in your project directory to specify ignore patterns. The .pewc file works exactly like .gitignore:

# Lines starting with # are comments

# Ignore specific files
bla.md
README.md
*.log
*.tmp

# Ignore directories (patterns ending with /)
node_modules/
dist/
build/

# Wildcards work just like in gitignore
doc/*.txt      # Ignore all .txt files in doc/ directory
test/*/data    # Ignore data in subdirectories of test/

Pattern Format

• Blank lines are ignored
• Lines starting with # are comments
• Patterns ending with / match directories only
• * matches any sequence of characters except /
• ? matches any single character except /
• You can specify exact filenames like bla.md to ignore them

Default Ignore Patterns

By default, pew ignores these patterns:

• .* (hidden files/directories)
• node_modules/
• target/
• dist/
• build/
• bin/
• pkg/
• .pewc (the configuration file itself)

Use --no-default-ignores to override this behavior.

Output

The output Markdown file contains:

1. A directory structure tree (if dumping a directory)
2. Code sections with proper syntax highlighting
3. All text files found in the specified location(s), excluding any files that match patterns in your .pewc file
