code-stats

Code-stats uses tokei for fast line-counting by language and difft for semantic AST-aware diffs to analyze codebase size, composition, and changes. Use it when needing quick project overviews, understanding code structure across languages, tracking codebase growth, or comparing file changes while ignoring formatting differences and recognizing code moves that traditional diffs miss.

# Code Statistics

Quickly analyze codebase size, composition, and changes.

## tokei - Line Counts

```bash
# Count all code
tokei

# Compact output sorted by code
tokei --compact --sort code

# Specific languages
tokei --type=TypeScript,JavaScript

# Exclude directories
tokei --exclude node_modules --exclude dist

# JSON output for scripting
tokei --output json | jq '.Total.code'
```

### Sample Output

```
===============================================================================
 Language            Files        Lines         Code     Comments       Blanks
===============================================================================
 TypeScript             45        12847         9823         1456         1568
 JavaScript             12         2341         1876          234          231
-------------------------------------------------------------------------------
 Total                  57        15188        11699         1690         1799
===============================================================================
```

## difft - Semantic Diffs

```bash
# Compare files
difft old.ts new.ts

# Inline mode
difft --display=inline old.ts new.ts

# With git
GIT_EXTERNAL_DIFF=difft git diff
GIT_EXTERNAL_DIFF=difft git show HEAD~1
```

### Why Semantic?

| Traditional diff | difft |
|-----------------|-------|
| Line-by-line | AST-aware |
| Shows moved as delete+add | Recognizes moves |
| Whitespace sensitive | Ignores formatting |

## Quick Reference

| Task | Command |
|------|---------|
| Count all code | `tokei` |
| Compact output | `tokei --compact` |
| Sort by code | `tokei --sort code` |
| TypeScript only | `tokei -t TypeScript` |
| JSON output | `tokei --output json` |
| Exclude dir | `tokei --exclude node_modules` |
| Semantic diff | `difft file1 file2` |
| Git diff | `GIT_EXTERNAL_DIFF=difft git diff` |

## When to Use

- Getting quick codebase overview
- Comparing code changes semantically
- Understanding project composition
- Reviewing refactoring impact
- Tracking codebase growth
