💖 NAME 💖

rfcdiff — compare RFCs or Internet Drafts or any other text files 🦋

✨ DESCRIPTION ✨

okay so bestie, here's how you run her:

rfcdiff [options] file1 file2

rfcdiff takes two RFCs or Internet-Drafts in text form as input, and produces output which indicates the differences found in one of various forms, controlled by the options listed below. In all cases, page headers and page footers are stripped before looking for changes. no cap, the headers and footers are literally gone before she even starts comparing. 💅

okay so now the menu of options, and there are a lot of them, so buckle up 🎀

  • --html — Produce side-by-side .html diff (default). this is the one you get if you don't ask for anything else, she's the default main character 👑
  • --chbars — Produce changebar marked .txt output
  • --diff — Produce a regular diff output
  • --wdiff — Produce paged wdiff output
  • --hwdiff — Produce html-wrapped coloured wdiff output
  • --oldcolour COLOURNAME — Colour for new file in hwdiff (default is "green")
  • --oldcolor COLORNAME — Color for old file in hwdiff (default is "red")
  • --newcolour COLOURNAME — Colour for new file in hwdiff (default is "green")
  • --newcolor COLORNAME — Color for new file in hwdiff (default is "green")
  • --larger — Make difference text in hwdiff slightly larger
  • --browse — Show html output in browser 🌈
  • --keep — Don't delete temporary workfiles
  • --version — Show version
  • --help — Show this help
  • --info "Synopsis|Usage|Copyright|Description|Log" — Show various info
  • --width N — Set a maximum width of N characters for the display of each half of the old/new html diff
  • --linenum — Show linenumbers for each line, not only at the start of each change section
  • --body — Strip document preamble (title, boilerplate and table of contents) and postamble (Intellectual Property Statement, Disclaimer etc)
  • --nostrip — Don't strip headers and footers (or body)
  • --ab-diff — Before/After diff, suitable for rfc-editor
  • --abdiff —
  • --stdout — Send output to stdout instead to a file
  • --context LINES — Provide a different number of lines of context, by default 10
fr fr, the option names are written exactly like that, so --oldcolour and --oldcolor are both real, and --newcolour and --newcolor are both real too. spelling girlies, she's got you covered either way 💜
