Hello
I accidentally have found a bug in rxapply, which actually resides in
rxfrom.
Have a look at a simple demonstration of the bug:
'a' |. rxapply 'A'
|length error: rxfrom
| r=.u&.>mat rxfrom y
I think that is a bug. It should return the original string if nothing is
to be matched and applied.
If you open up the regex.ijs and find up the definition of rxfrom, you can
see a commented out definition of rxfrom which is different from the
current one. If you use that instead,
rxfrom=: <@({~ (+ i.)/)"1~
'a' |. rxapply 'A'
A
