String functions and one-liners.

I have noticed that a lot of array functions can be replaced with an equivalent string function.

This is a collection of String functions and one-liners for String manipulation, which, I hope, will encourage thinking outside of the array box.

I like _StringRepeatRE at about line #100 in script, a lot.

Here is a link to similar one-liners (no arrays) for extracting parts from a fullpath, file name string.

Added:Post#5 - String displayed as a transposed 2D array.

Cheers Malkey; you're exactly right when you say this type of nfo encourages outside of the box thinking :D - if you or anyone else could be bothered to do benchmarks on these functions it would be a brilliant and natural followup on the work you have done. Could it theory mean that a performance based replacement UDF include file for all these operations.

Thanks again,

Sunaj

This is a collection of String functions and one-liners for String manipulation, which, I hope, will encourage thinking outside of the array box.

I like _StringRepeatRE at about line #100 in script, a lot.

Here is a link to similar one-liners (no arrays) for extracting parts from a fullpath, file name string.

Brilliant!!!

I don't get to imagine like "DEV" didn't have this idea...

Fantastic, fast, elegant and simple, still reduces the size of the executable.

Will we transform this in UDF?

This script displays a "@CRLF" separated, segmented string as a transposed 2D array.

I had to.

jscript

There is really only the sort function, 1st post, and this one, that could go into a UDF.

The rest are one-liners using the AutoIt built-in command StringRegExpReplace.

So I lean towards the efficiency of using one-liners, as opposed to calling the same one-liner from within a function.

I can't imagine how a UDO-L, (User Defined One-Liner) file would work:)

Malkey

Just a thought. Auto-inclusion into SciTE's Snippet Holder, (Ctrl+Alt+s), could have some merit.
