How can I capture the following groups using the same regex?
Example A:
Input: something-E123
Output:
Capture group to Variables:
Variable 1: something
Variable 2: E123
⠀⠀⠀⠀⠀⠀
Example B:
Input: some-text-EABC
Output:
Capture group to Variables:
Variable 1: some-text
Variable 2: EABC
⠀⠀⠀⠀⠀⠀
Example C:
Input: something-something-moretext-EA1A
Output:
Capture group to Variables:
Variable 1: something-something
Variable 2: EA1A
Note: If it helps, the last 4 characters are always "EXXX", where XXX are four characters from A-Z or 0-9
Previously had been using this Regex: ([^=]*)-([^=]*)
It works for Example A, when there is only one - hyphen character, but doesn't work on Examples B or C when there's two or more hyphens present.
Unless practicing regular expressions is a higher priority than capturing the final string, it might be simpler to split on hyphens and take the last value from the resulting list.
If you did that in JS for example, perhaps:
Expand disclosure triangle to view JS Source
(() => {
"use strict";
const main = () => {
const
s = Application("Keyboard Maestro Engine")
.getvariable("someHyphenatedString");
// Split on all hyphens
const xs = s.split("-");
return last(xs);
};
// --------------------- GENERIC ---------------------
// last :: [a] -> a
const last = xs =>
// The last item of a list.
0 < xs.length ? (
xs.slice(-1)[0]
) : null;
return main();
})();
or in AppleScript:
Expand disclosure triangle to view AppleScript
--------------------------- TEST -------------------------
on run
tell application "Keyboard Maestro Engine"
set s to getvariable "someHyphenatedString"
end tell
set xs to splitOn("-", s)
last item of xs
end run
------------------------- GENERIC ------------------------
-- splitOn :: String -> String -> [String]
on splitOn(needle, haystack)
set {dlm, my text item delimiters} to ¬
{my text item delimiters, needle}
set xs to text items of haystack
set my text item delimiters to dlm
return xs
end splitOn
