💖 REGCONCAT — combine several Regina data files 💖

okay bestie, you know how you've got like seventeen separate Regina files lying around and you're like "why are these not one file 😭"? yeah. that's what regconcat is for. it's a command-line utility from the Regina handbook, and it's lowkey iconic. let's get into it 🫶

✨ SYNOPSIS ✨

regconcat [ -o output-file ] input-file ...
regconcat { -v, --version | -?, --help }

🌸 DESCRIPTION 🌸

so here's the vibe: this utility takes several individual Regina data files and smushes them together into one single bigger data file. no cap.

the new file gets a container as its top-level packet, and underneath that container you'll find the packet trees from each of the input files you supplied. so like, everyone's invited to the party, and the container is the host 💅

now, if you specify an output file with the -o option, the new file gets written as compressed XML to that output file. cute and tidy.

otherwise? the new file is written as uncompressed XML to standard output. so if you don't hand it a destination, it just starts yapping straight into your terminal. which, honestly, sometimes you want! redirect it yourself if you don't 🙈

🎀 OPTIONS 🎀

  • -o output-file — tells regconcat that the new combined data file should be written as compressed XML to the given output file. that's it, that's the whole job. queen behavior.
  • -v, --version — shows you which version of Regina is being used, then exits immediately. like, no further questions, she's gone 💨
  • -?, --help — displays brief usage information, and exits immediately. your little cheat sheet, bestie ✨

🍓 MACOS USERS 🍓

if you downloaded a drag-and-drop app bundle, this utility is shipped inside it. sneaky little thing, living in there.

if you dragged Regina to the main Applications folder, you can run it as:

/Applications/Regina.app/Contents/MacOS/regconcat

yes, all the way down there. that's just where she lives now 💀

🦋 WINDOWS USERS 🦋

the command-line utilities are installed beneath the Program Files directory. on some machines this directory is called Program Files (x86) — same energy, different name, don't let it confuse you.

you can start this utility by running:

c:\Program Files\Regina\Regina 7.4.1\bin\regconcat.exe

that long path is literally giving "trust the process" 😭
