okay so welcome to CL(1), bestie!! 💖 this is a page from the IRAF commands manual and it's all about the CL — no, not Common Lisp, we'll get to that drama in a sec. sit down, grab a strawberry 🍓, let's go.

✨ NAME ✨

IRAFCL — the IRAF Command Language Interpreter. that's it, that's the name, she's iconic. 👑

🌸 SYNOPSIS 🌸

irafcl [-V|-c|-e] [-f FILE]

ecl [-V|-c|-e] [-f FILE]

cl [-V|-c|-e] [-f FILE]

three whole names for the same girlie, we love a versatile queen. 💅

🦋 DESCRIPTION 🦋

so irafcl, ecl or cl starts up the command language interpreter for IRAF, the Image Reduction and Analysis Facility. and the way it works is you can literally feed it a whole series of commands and it will execute them in sequence, one after another. line by line. no cap. ✨

now. the ECL (that's the Enhanced CL, keep up 🫶) has a bunch of features over plain CL, and honestly? it ate:

  • better error handling 😭
  • command line editing ✍️
  • new functions and constants 🎀

and like — unless you have a compatibility reason not to, you should be using ECL over CL. periodt. the classic CL is only for when something old needs it, iykyk.

here's the messy part: the names ecl and cl conflict with other super commonly used command names for Common Lisp. yes, really. so the canonical name of the interpreter is irafcl — and she defaults to ECL behaviour because of course she does, she's the main character. 👑

🎀 the flags 🎀

  • -V — show the version of the program. quick lil vibe check. ⭐
  • -e — force the enhanced CL (command line editing etc.). bestie mode: on. 💖
  • -c — force the classic CL. retro era, respect it. 🙈
  • -x — start in a new xgterm (or xterm if xgterm isn't available). window pop-off time. 🌈
  • -f FILE — start with executing FILE. like, immediately, first thing. 🔥
