Regular expression function

[asirota]

Is 2.0 of WATM supporting regex expressions in default or alternative text in 2.0?

If we are supporting RegEx's we need to have a toggle to turn that off because people can search for things like [ and ( and forget to escape these characters causing all sorts of trouble.

If we don't support Regular Expression, we should add support and add a toggle to turn it on or off, with Regex=off being the default.

2.0 does not support regex - this can be added as a new function, separate from the normal replace function.

What would be a use-case for this however?

[asirota]

oh that's actually good -- the use case would be remote and only for very technical people that wanted to find and replace patterns of text not actual specific words... Let's leave it off for now.

Here's one use case for the regex function - replacing the : for an h in time patterns

12:00 -> 12h00
19:59 -> 19h59

The default text would be the regular expression pattern to search, and the replacement text would have the regex pattern to use for replacement of the : character

default text: matches 24 hour HH:MM format

([0-9]|0[0-9]|1[0-9]|2[0-3]):([0-5][0-9])

this could be the replacement text
$1h$2

where $1 and $2 are the matching groups from the default text
