Re: [bug-gawk] funcsub func needed

[Kjetil Flovild-Midtlie]

Yes the awk impl of this new func is:


# kind of like gensub(global flag on)
# but expands grp-values
# ( userData is also a new feature )
#
# 60 TIMES slower than gensub !!!!!!!!!!
#
# .. I need a C version of this

# replaceFn has this signature:: (arr,userData) returns string

function funcsub(regex,replaceFn,userData,target){
  newVal = target

  while (match(target,regex,grps)) {
    singleHit = substr(target, RSTART, RLENGTH);
    sub(singleHit, @replaceFn(grps,userData),newVal)
    # shift;
    target = substr(target, RSTART + RLENGTH);
  }

  return newVal

}
