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

# 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

GIT_EXTERNAL_DIFF=difft git show HEAD~1Why Semantic?
| Traditional diff | difft | |-----------------|-------| | Line-by-line | AST-aware | | Shows moved as delete+add | Recognizes moves | | Whitespace sensitive | Ignores formatting |
