Guide for setup Codemap CLI
1. Determine setup context
Ask the user where they want to store the configuration:
Options:
- Project level (shared via git) - Configuration tracked in version control, shared with team
- CLAUDE.md updates go to:
./CLAUDE.md
- Hook settings go to:
./.claude/settings.json
-
Project level (personal preferences) - Configuration stays local, not tracked in git
- CLAUDE.md updates go to:
./CLAUDE.local.md
- Hook settings go to:
./.claude/settings.local.json
- Verify these files are listed in
.gitignore, add them if not
-
User level (global) - Configuration applies to all projects for this user
- CLAUDE.md updates go to:
~/.claude/CLAUDE.md
- Hook settings go to:
~/.claude/settings.json
Store the user's choice and use the appropriate paths in subsequent steps.
2. Check if Codemap is already installed
Check whether codemap is installed by running codemap -help.
If not installed, proceed with setup.
3. Load Codemap documentation
Read the following documentation to understand Codemap's capabilities:
- Load https://raw.githubusercontent.com/JordanCoin/codemap/refs/heads/main/README.md to understand what Codemap is and its capabilities
4. Guide user through installation
macOS/Linux (Homebrew)
brew tap JordanCoin/tap && brew install codemap
Windows (Scoop)
scoop bucket add codemap https://github.com/JordanCoin/scoop-codemap
scoop install codemap
5. Verify installation
After installation, verify codemap works:
codemap .
6. Update CLAUDE.md file
Use the path determined in step 1. Once Codemap is successfully installed, update the appropriate CLAUDE.md file with the following content:
## Use Codemap CLI for Codebase Navigation
Codemap CLI is available for intelligent codebase visualization and navigation.
**Required Usage** - You MUST use `codemap --diff --ref master` to research changes different from default branch, and `git diff` + `git status` to research current working state.
### 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
### 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
`--json`
Output JSON
**Smart pattern matching** - no quotes needed:
- `.png` - any `.png` file
- `Fonts` - any `/Fonts/` directory
- `*Test*` - glob pattern
### Diff Mode
See what you're working on:
codemap --diff
codemap --diff --ref develop
if the default branch is not main, but instead master (or something else) update content accordingly:
- use codemap --diff --ref master instead of regular codemap --diff
7. Update .gitignore file
Update .gitignore file to include .codemap/ directory:
.codemap/
8. Test Codemap
Run a quick test to verify everything works:
codemap .
codemap --diff
9. Add hooks to settings file
-
Use the settings path determined in step 1. Create the settings file if it doesn't exist and add the following content:
{
"hooks": {
"session-start": "codemap hook session-start && echo 'git diff:' && git diff --stat && echo 'git status:' && git status"
}
}
if default branch is not main, but instead master (or something else) update content accordingly:
- use
codemap hook session-start --ref=masterinstead of regularcodemap hook session-start
- For rest of commands also add
--ref=masterflag.
-
Ask user whether he want to add any other hooks and provide list of options with descriptions. Add hooks that he asks for.
Available Hooks
Command
Trigger
Description
codemap hook session-start
SessionStart
Full tree, hubs, branch diff, last session context
codemap hook pre-edit
PreToolUse (Edit|Write)
Who imports file + what hubs it imports
codemap hook post-edit
PostToolUse (Edit|Write)
Impact of changes (same as pre-edit)
codemap hook prompt-submit
UserPromptSubmit
Hub context for mentioned files + session progress
codemap hook pre-compact
PreCompact
Saves hub state to .codemap/hubs.txt
codemap hook session-stop
SessionEnd
Edit timeline with line counts and stats
