CHECK-REGEXP(1)

💖 CHECK-REGEXP(1) — the group chat version 💖

okay bestie, so this is a User Commands page for check-regexp, and honestly? it's giving "tiny tool, huge main character energy." ✨

🌸 NAME 🌸

check-regexp — test regular expressions from the command line 🎀

🦋 SYNOPSIS 🦋

check-regexp 'regular expression' 'string1' 'string2' ...

💅 DESCRIPTION 💅

so check-regexp is part of GNU Source-highlight, and it's literally the simplest little vibe: you pass your regular expression as the first command line argument, and then all the strings you wanna try to match after it. that's it. that's the whole thing. 💖

okay but listen — this part is CRUCIAL, no cap: to avoid shell substitutions you have to wrap both the expression and the strings in single quotes. like, both. the expression and the strings. do not skip this. the shell will eat your regex and you'll be sitting there like 🧍‍♀️

then the program prints some info about the possibly-successful matching. 🔥

in that output:

• the what[0] part represents the whole match
• the what[i] part represents the i-th marked subexpression that matched 👑

and it also prints possible prefix and suffix, because it's thorough like that. 💅

✨ OPTIONS ✨

this program follows the usual GNU command line syntax, with long options starting with two dashes (-). a summary of the options is included below, bestie. 🫶

• -h, --help — print help and exit 😌
• -V, --version — print version and exit 💀
