Command-line interface

Installing PyReprism provides a pyreprism command (equivalently python -m PyReprism). It reads from stdin, files, globs, or directories, and auto-detects the language from a file’s extension (or a #! shebang on stdin) when --lang is omitted.

Common usage

pyreprism remove comments file.py
cat file.go | pyreprism remove comments --lang go
pyreprism extract comments "src/**/*.py" --json
pyreprism count comments file.py --lang python
pyreprism preprocess --steps comments,strings,whitespace file.java
pyreprism tokenize --json file.py
pyreprism normalize file.py
pyreprism stats --json file.py

Directories and reports

pyreprism scan myproject/ --csv              # aggregate metrics over a tree
pyreprism scan myproject/ --json --per-file
pyreprism remove comments src/ --output out/ # bulk-transform, mirroring the tree
pyreprism remove comments file.py --in-place

Options

  • -l, --lang — language name, extension, or class.

  • -e, --engine — regex (default), pygments, or auto.

  • -o, --output DIR — write results into DIR, mirroring the input tree.

  • -i, --in-place — rewrite files in place.

  • --json / --csv — machine-readable output where supported.
