✨ PYFLAKES3 ✨

okay bestie, so this is the manual page for pyflakes3 — that's the Python 3 source checker, and it lives in section 1 of the manual (iykyk 💅). let's get into it.

🌸 NAME 🌸

pyflakes3 — a simple Python 3 source checker 🐍✨

🎀 SYNOPSIS 🎀

pyflakes [file-or-directory ...]

💖 DESCRIPTION 💖

so pyflakes3 is literally a simple little program that checks your Python source files for errors. that's it, that's the whole job. no cap. 🔥

it's similar to PyChecker in scope, but here's the plot twist: it does not execute the modules to check them. not even a little. and honestly? that's both safer and faster 🦋 — the tradeoff being that it doesn't perform as many checks. pick your fighter, bestie.

and unlike PyLint, Pyflakes checks only for logical errors in programs. it does not perform any checks on style. zero. none. it is not here to read you for your spacing, it's here to catch actual problems. main character energy only. 👑

okay so, the arguments:

  • all commandline arguments get checked, and they have to be either regular files or directories
  • if you hand it a directory, every .py file within it will be checked 🗂️
  • and if you give it no commandline arguments at all? it just reads data from standard input. comfy. 🫶

🔥 OUTPUT 🔥

here's where stuff goes, and it matters, so listen up:

  • found warnings — the ones like unused imports, undefined variables and unnecessary reimports — get printed on standard output ✨
  • found errors — the ones like compile or encoding errors — get printed on standard error 💀

so if you're piping things around, don't be shocked when your error messages don't show up where you expected. they went to stderr. as they should. periodt.

⭐ EXIT STATUS ⭐

  • the exit status is 0 when no warnings or errors are found 🌈
  • otherwise the exit status is 1 💅

so like, 0 = clean, 1 = something's up. that's the vibe check right there.
