    YAPF (Yet Another Python Formatter): YAPF takes a different approach in that it’s based off of ‘clang-format’, a popular formatter for C++ code. YAPF reformats Python code so that it conforms to the style guide and looks good.

    I think I agree about the testing and labor of complicated translation rules.

    But it doesn't appear that almost every pretty printer uses the Wadler pretty printing paper. It seems like MOST of them don't?

    e.g. clang-format is one of the biggest and best, and it has a model that includes "unwrapped lines", a "layouter", a line break cost function, exhaustive search with memoization, and Dijikstra's algorithm:

    The YAPF Python formatter is based on this same algorithm - https://github.com/google/yapf

    The Dart formatter used a model of "chunks, rules, and spans"

    https://journal.stuffwithstuff.com/2015/09/08/the-hardest-pr...

    It almost seems like there are 2 camps -- the functional algorithms for functional/expression-based languages, and other algorithms for more statement-based languages.

    Though I guess Prettier/JavaScript falls on the functional side.

    I just ran across this survey on lobste.rs and it seems to cover the functional pretty printing languages influenced by Wadler, but functional style, but not the other kind of formatter ("Google" formatters perhaps)

    To get all your code into a consistent format the next step is to run a formatter. I recommend black, the well-known uncompromising code formatter, which is the most popular choice. Alternatives to black are autoflake, prettier and yapf, if you do not agree with blacks constraints.

    Only as recommendation: If the lines of the source code (here: you C code you aim to document) are kept short, in manageable bytes (similar to entries parser.add_argument in Clark's "Tiny Python Projects", example seldomly pass beyond the frequently recommended threshold of 80 characters/line), reporting with listings becomes easier (equally, the reading of the difference logs/views by git and vimdiff), than with lines of say 120 characters per line. Though we no longer are constrained to 80 characters per line by terminals/screens and punch cards (when Fortran still was FORTRAN), this is a reason e.g., yapf for Python allows you to choose between 4 spaces/indentation (PEP8 style), or 2 spaces/indentation (Google style).
  • Which code formatter do you use?

    YAPF. Black would have been fine too but I absolutely need tabs, not spaces, and Black won't do that. (Why tabs? Because they make my proportional font work better.)

  • From Python to Dart - Day 2, Meet the dart CLI

    When working with several people on one project, it is very often necessary to use a single style of code design, writing comments, using variable names, etc. In the Python world, we use linters flake8, various formatters (black, yapf, autopep8) and mypy for type checking. How can Dart help meet these challenges?

What are some alternatives?

When comparing pyflakes and yapf you can also consider the following projects:

black - The uncompromising Python code formatter

isort - A Python utility / library to sort imports.

flake8

autopep8 - A tool that automatically formats Python code to conform to the PEP 8 style guide.

awesome-python-typing - Collection of awesome Python types, stubs, plugins, and tools to work with them.

pycodestyle - Simple Python style checker in one Python file

pyright - Static Type Checker for Python

vim-sleuth - sleuth.vim: Heuristically set buffer options

prettier - Prettier is an opinionated code formatter.

pylama - Code audit tool for python.
