🎀 NAME 🎀

usddiff — manual page for usddiff 26.11.1, aka the usddiff(1) manual, bestie. That's the whole NAME section and it's already iconic. ✨

🌸 DESCRIPTION 🌸

okay so first, the usage is exactly this, no edits:

usage: usddiff [-h] [-n] [-f] [-q] files [files ...]

usddiff compares two usd-readable files using a selected diff program. The selection is lowkey a little env-var quest: it's chosen by looking at $USD_DIFF; if that's unset, it consults $DIFF; and lastly, if neither of those is set, it tries the canonical unix program, diff. It will relay the exit code of the selected diff program — yes, the exit code, bestie, don't forget it.

When comparing two usdz files, each file contained in the package will be examined individually. The $USD_IMAGE_DIFF environment variable specifies a specific diff program for comparing image files. The $USD_IMAGE_DIFF_FORMATS environment variable specifies supported image formats using a , separated list of file extensions. Fr fr, that's the whole format situation. 🦋

🫶 positional arguments 🫶

  • files — The files to compare. These must be of the form DIR DIR, FILE... DIR, DIR FILE... or FILE FILE.

💅 options 💅

  • -h, --help — show this help message and exit
  • -n, --noeffect — Do not edit either file.
  • -f, --flatten — Fully compose both layers as Usd Stages and flatten into single layers.
  • -q, --brief — Do not return full results of diffs. Passes --brief to the diff command.
