Hello!

I feel like I'm reviving an old thread here...

I'm trying to match a string of text in a named wildcard, but the pattern that this text can appear means I must use the named capturing group more than once ie:

match="^ * (Her|His|Its) skin (?J)(?P<strength>(has been hardened to a rock-like form|has been hardened with numerous layers of a mineral-like substance)), although (.*).$|^ * (Her|His|Its) (?P<strength>(has tiny threads of metal running all over it)), although (.*).$"

I've entered the (?J) as mentioned in a previous thread which fixed the Error "Failed: two named subpatterns have the same name at offset..." error but it still seems to mess up when it triggers.

[string "Plugin"]:2592: bad argument #3 to 'ArraySet' (string expected, got nil)
stack traceback:
[C]: in function 'ArraySet'
[string "Plugin"]:2592: in function <[string "Plugin"]:2555>

Using Mushclient Version 4.94

-- This is what i'm trying to capture --

* His has tiny threads of metal running all over it, although the stomach seems not to be covered.

or

* Tiny threads of metal run criss-cross all over your skin, although the head seems not to be covered.

Please post the actual trigger:

I can't see what your script is doing, but with this test script:


function shield_up (name, line, wildcards)
  require "tprint"
  tprint (wildcards)
end -- shield_up

With your test data I get:


1=""
2=""
3=""
4=""
5="His"
6="has tiny threads of metal running all over it"
7="the stomach seems not to be covered"
0=" * His has tiny threads of metal running all over it, although the stomach seems not to be covered."
"strength"="has tiny threads of metal running all over it"

In other words, the "strength" wildcard is the one to use. The other wildcards (1, 2, 3, 4) are empty because they didn't match.
