Code Stats

Analyze codebase with tokei (fast line counts by language) and difft (semantic AST-aware diffs). Get quick project overview without manual counting. Triggers on: how big is codebase, count lines of code, what languages, show semantic diff, compare files, code statistics.

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
