Code Statistics
Quickly analyze codebase size, composition, and changes.
tokei - Line Counts
# 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

difft - Semantic Diffs
# 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
