inspectr

A collection of python tools to inspect code quality.

Installation

python -m venv .venv/
source .venv/bin/activate
pip install inspectr

Usage

Generally, the syntax goes:

inspectr <subtool> [options] [files...]

where <subtool> is one of the following:

• authenticity: looks for TODO comments, empty try/except blocks, and stub functions
• bare_ratio: checks for the ratio of bare excepts to meaningful exception usage
• compare_funcs: compares function/method names across two directory versions
• complexity: analyzes algorithmic complexity of Python code
• count_exceptions: counts how many of each type of exception there are (including bare except)
• duplicates: looks for occurrences of duplicate or similar code (>80% similarity, default: 10+ lines, 3+ occurrences)
• size_counts: various linecount-related code complexity checks
• with_open: checks for open in the absense of with and manual calls to close()

Command-Line Options

All tools accept command-line options in the format --option-name value. Options are passed as keyword arguments to the tool's main function. For example:

inspectr duplicates --block-size 15 --min-occur 2 file1.py file2.py

Recognized options include:

• duplicates:
  • --block-size N: number of consecutive lines in a block (default: 10)
  • --min-occur N: minimum number of occurrences to report (default: 3

Note: any unrecognized options will be silently ignored.

Usage for compare_funcs

The compare_funcs tool compares functions across two directory versions:

inspectr compare_funcs files_list.txt dir1 dir2

where files_list.txt contains relative paths to compare, one per line.

Local Testing

First install in development mode with test dependencies, then run the tests:

git clone https://github.com/ajcm474/inspectr.git
cd inspectr
pip install -e ".[test]"
pytest tests/

Please note: this project is in the early alpha stage, so don't expect the above subtool names to be stable between versions. I might even merge/split them at some point.
