A Python linter focused on naming conventions with 5 strictness levels

yina

A simple, yet opinionated linter for Python that helps you choose more descriptive variable names.

pip install yina

Usage

• Run yina lint file.py to lint a file or yina lint src/ for a directory.
• Use the --level N option to specify the strictness level. Defaults to level 3.
• With yina init you can generate a configuration file for the working directory with default values you can edit.

Strictness levels

Yina lint operates on 5 strictness levels. Each level includes all the rules from the previous levels.

Level	Rules
Level 1: Length and charset	- Variables must be at least 3 characters long. - Variables can only contain characters: a-Z, A-Z, 0-9 and _. - Variables cannot start with a number.
Level 2: Naming conventions	- Snake case will be enforced for regular variables and camel case for class names. - All constants must be fully capitalized. - Snake case variables that are not constants cannot have capital letters.
Level 3 (default): Word length, max length, repetition	- Max variable length: 32 characters. - No more than 2 underscores in a row. - Applied for each "word" in a variable name, like "one" in "one_two_three":   - No more than 2 of the same letter in a row.   - At least 3 characters long.
Level 4: Pronounceability	- Applied for each "word" in a variable name, like "one" in "one_two_three":   - At least one vowel   - No more than 4 consonants in a row
Level 5: Non vagueness	- No vague words like "item(s)", "thing(s)", "object(s)", "element(s)", "data", "value" or "result". "string" or "dataframe" are also disallowed. Applies only to the entire variable name, vague segments are allowed. - No numbers.

Configuration

• If there is a .yina.toml file in the working directory, it will be used.
• If not, the default yina-lint/config/yina.toml file will be applied.
