💅 nydiff — compare two versions of a specialized-format patch 💅

okay bestie, welcome to the NYDIFF(1) page. grab ur iced coffee, we're doing patch diffs 💖

🎀 NAME 🎀

nydiff — tool to compare two versions of a specialized-format patch.

✨ SYNOPSIS ✨

nydiff oldpam newpam name options [ print ] [ .go ]

🦋 DESCRIPTION 🦋

nydiff is one of the Nypatchy suite of programs for working with Patchy Master Files (PAM files); see nypatchy(1). Specifically, it compares two different versions of the same PAM file and generates a "correction patch" that can be used by nypatchy to update the older version to the newer version. literally the glow-up pipeline 💅

🌸 USAGE 🌸

okay so here's the cast of characters:

  • oldpam — the name of the older version of the PAM file (a default extension of .car is assumed).
  • newpam — the name of the newer version.
  • print — the output file to write to (the default is standard output if omitted).
  • options — a sequence of single-character flags.
  • name — the name to be used for the correction file to be generated. the specific filename will be name.ucra for a correction patch to be used by Nypatchy.

The command should be ended with .go unless one wants to enter the Nypatchy interactive shell. yes bestie, .go is the little send button 🫶

🔥 OPTIONS 🔥

note that options should be given as a single string of characters with no space separation and no use of the - character (except that it can be used in place of the options field if no options are desired). alphabetic options are not case-sensitive — iconic, honestly ✨
  • A — "anyway" — bypass the first sanity check on sufficient matching.
  • F — "force" — bypass the second sanity check on sufficient matching.
  • H — print help information only.
