By Jonesy44 on Apr 07, 2009Regex?
Regex (Regular Expressions) is an advanced search/find function in a string of text/unicode.
How does this tool help?
This tool simply helps by letting you enter the string of text to "search" then entering the expression to match it with. It will return whether a match was found. and the sections to be returned (regml(x)). This makes it easy to find the section you want
Extras
It also has a "notepad" so you can put your own notes in, this is helpful since there are MANY identifiers and denoations for regex. even I, the god of everything cannot remember everyone of them
Instructions
Load the script into remotes (Alt+R). Usage is /rxt [$regex(string,exp)]

Special Character Definitions
Note: not all of these may apply to mIRC but the vast majority do.
\ Quote the next metacharacter
^ Match the beginning of the line
. Match any character (except newline)
$ Match the end of the line (or before newline at the end)
| Alternation
() Grouping
[] Character class
---unsure about these---
{n} Match exactly n times
{n,} Match at least n times
{n,m} Match at least n but not more than m times
\t tab (HT, TAB)
\n newline (LF, NL)
\r return (CR)
\f form feed (FF)
\a alarm (bell) (BEL)
\e escape (think troff) (ESC)
\033 octal char (think of a PDP-11)
\x1B hex char
\c[ control char
\E end case modification (think vi)
\Q quote (disable) pattern metacharacters till \E
\A Match only at beginning of string
\Z Match only at end of string, or before newline at the end
\z Match only at end of string
\G Match only where previous m//g left off (works only with /g)
looks nice, this might inspire me to learn regex. I don't know if this would be possible (and it would probably be very difficult to make) but what would be really cool is if you could set 2 variables, a pre and post..and then the script/program would tell you the regex needed to get from pre to post. Just a thought if anyone wants to try that :p
Anyway nice job and I'm sure I'll be using this in the future :)
Here's some basic stuff:
? - The question mark indicates there is zero or one of the preceding element.
- The asterisk indicates there are zero or more of the preceding element.
- The plus sign indicates that there is one or more of the preceding element.
. - Matches any single character.
| - Matches either the expression before or the expression after the operator.
^ - Matches the starting position within the string.
$ - Matches the ending position of the string.
[ ] - Matches a single character that is contained within the brackets. [abc] [a-c]
[^ ] - Matches a single character that is not contained within the brackets.
{m,n} - Matches the preceding element at least m and not more than n times. (n optional)
