Quick Start

codemap .                    # Project tree
codemap --only swift .       # Just Swift files
codemap --exclude .xcassets,Fonts,.png .  # Hide assets
codemap --depth 2 .          # Limit depth
codemap --diff               # What changed vs main
codemap --deps .             # Dependency flow
codemap github.com/user/repo # Remote GitHub repo

Options

| Flag | Description | |------|-------------| | --depth, -d <n> | Limit tree depth (0 = unlimited) | | --only <exts> | Only show files with these extensions | | --exclude <patterns> | Exclude files matching patterns | | --diff | Show files changed vs main branch | | --ref <branch> | Branch to compare against (with --diff) | | --deps | Dependency flow mode | | --importers <file> | Check who imports a file | | --skyline | City skyline visualization | | --animate | Animate the skyline (use with --skyline) | | --json | Output JSON |

Note: Flags must come before the path/URL: codemap --json github.com/user/repo

Smart pattern matching — no quotes needed:

.png → any .png file
Fonts → any /Fonts/ directory
*Test* → glob pattern
