vi-hater's cheat sheet for vi:
- i: Stop beeping at me and enter writing mode you stupid program
- esc-:-w-q-enter: Save and quit
- esc-:-q-!-enter: Quit without saving
- esc-d-d: Delete a line because backspace isn't good enough for you
- esc-esc-esc: what in the world are you doing now, quit it, stop doing that
Haha, yes ... The only time I use vi is when installing NetBSD occasionaly on some of my old hardware for kicks. But it is ubiquitous... its hard to find a Nix install without some version of it. Also that keyboard has Ctrl in the right place... non the abominable caps lock key.
nano or pico are the go to console editors for me... and I have strangely fond memories of edit in a DOS prompt, which I suppose is part of why I like the minimum profit editor...

I've been using the atom editor (quite bloaty honestly)... but it integrates pretty decently with a dozen plus microcontroller toolchains as well as libraries for tons of things like the little LoRa boards I have been experimenting with.

regexp::common::delimited
Regexp::Common::delimited(3) User Contributed Perl Documentation Regexp::Common::delimited(3)
NAME
Regexp::Common::delimited -- provides a regex for delimited strings
SYNOPSIS
use Regexp::Common qw /delimited/;
while (<>) {
/$RE{delimited}{-delim=>'"'}/ and print 'a " delimited string';
/$RE{delimited}{-delim=>'/'}/ and print 'a / delimited string';
}
DESCRIPTION
Please consult the manual of Regexp::Common for a general description of the works of this interface.
Do not use this module directly, but load it via Regexp::Common.
$RE{delimited}{-delim}{-esc}
Returns a pattern that matches a single-character-delimited substring, with optional internal escaping of the delimiter.
When "-delim=S" is specified, each character in the sequence S is a possible delimiter. There is no default delimiter, so this flag must
always be specified.
If "-esc=S" is specified, each character in the sequence S is the delimiter for the corresponding character in the "-delim=S" list. The
default escape is backslash.
For example:
$RE{delimited}{-delim=>'"'} # match "a " delimited string"
$RE{delimited}{-delim=>'"'}{-esc=>'"'} # match "a "" delimited string"
$RE{delimited}{-delim=>'/'} # match /a / delimited string/
$RE{delimited}{-delim=>q{'"}} # match "string" or 'string'
Under "-keep" (See Regexp::Common):
$1 captures the entire match
$2 captures the opening delimiter (provided only one delimiter was specified)
$3 captures delimited portion of the string (provided only one delimiter was specified)
$4 captures the closing delimiter (provided only one delimiter was specified)
$RE{quoted}{-esc}
A synonym for $RE{delimited}{q{-delim='"`}{...}}
