# Functions #################################################################

# newpl - creates a basic Perl script file and opens it with $EDITOR 
newpl () {
	# set $EDITOR to 'vim' if it is undefined
	[[ -z $EDITOR ]] && EDITOR=vim

	# if the file exists, just open it
	[[ -e $1 ]] && print "$1 exists; not modifying.\n" && $EDITOR $1

	# if it doesn't, make it, and open it
	[[ ! -e $1 ]] && print '#!/usr/bin/perl'"\n"'use strict;'"\n"'use warnings;'\
		"\n\n" > $1 && $EDITOR $1
}


# pgs - Perl Global Substitution
# find pattern		= 1st arg
# replace pattern	= 2nd arg
# filename			= 3rd arg
pgs() { # [find] [replace] [filename]
    perl -i.orig -pe 's/'"$1"'/'"$2"'/g' "$3"
}


# Perl grep, because 'grep -P' is terrible. Lets you work with pipes or files.
prep() { # [pattern] [filename unless STDOUT]
    perl -nle 'print if /'"$1"'/;' $2
}

# say - append a newline to 'print'
say() {
    print "$1\n"
}
