Irregular Expressions
by TenFont​

Irregular Expressions are code snippets that I created by utilizing RegEx (Regular expressions). Credit is given where credit is due.


1 Floor Timespan
A simple function to round down a timespan, eliminating all decimals.

Spoiler: Snippet

function floorTimespan(time: timespan) :: timespan:
    set {_s} to join (regex split "%{_time}%" at ".\d+")
    return {_s} parsed as timespan

Spoiler: Usage

set {_a} to "2 minutes and 37.49 seconds" parsed as timespan
broadcast floorTimespan({_a})
# output: 2 minutes and 37 seconds

2 Split String At Every N Characters
Efficiently splits a string at every N characters.

Spoiler: Snippet

function splitAt(str: string, n: integer) :: strings:
    if {_n} > 0:
        return regex split {_str} at "(?<=\G.{%{_n}%})"
    return {_str}

Spoiler: Usage

broadcast splitAt("ABCDEFG", 2)
# output: AB, CD, EF and G

3 Format A Number With Commas
Format a number with commas, making it more readable. Also accepts decimals.

Spoiler: Snippet

function formatNumber(x: num) :: string:
    set {_x::*} to split "%{_x}%" at "."
    set {_x::1} to (join (regex split {_x::1} at "(?<=\d)(?=(\d\d\d)+(?!\d))") by ",")
    return join {_x::*} by "."

Spoiler: Usage

broadcast formatNumber(10000000.389)
# output: 10,000,000.39
