Command Reference: regexp

Regexp tools for arrays / lists of strings

Description

regexp provides a few tools for text matching and manipulation against an array or list of strings - thus regexp is murex data-type aware.

Usage

<stdin> -> regexp expression -> <stdout>

Examples

Find elements

» ja: [monday..sunday] -> regexp 'f/^([a-z]{3})day/'
[
    "mon",
    "fri",
    "sun"
]

This returns only 3 days because only 3 days match the expression (where the days have to be 6 characters long) and then it only returns the first 3 characters because those are inside the parenthesis.

Match elements

Elements containing

» ja: [monday..sunday] -> regexp 'm/(mon|fri|sun)day/'
[
    "monday",
    "friday",
    "sunday"
]

Elements excluding

» ja: [monday..sunday] -> !regexp 'm/(mon|fri|sun)day/'
[
    "tuesday",
    "wednesday",
    "thursday",
    "saturday"
]

Substitute expression

» ja: [monday..sunday] -> regexp 's/day/night/'
[
    "monnight",
    "tuesnight",
    "wednesnight",
    "thursnight",
    "frinight",
    "saturnight",
    "sunnight"
]

Flags

Detail

regexp is data-type aware so will work against lists or arrays of whichever murex data-type is passed to it via STDIN and return the output in the same data-type.
