Class Method Details

.gsub_tagger(patcher, preshift, ret, block) ⇒ Object

gsub is hard. there are four versions of this method 1) pattern, replacement (my fav) 2) pattern, hash (not bad) 3) pattern, block (are you kidding me?) 4) pattern (plz no)

In addition, it requires things from $~ & $1-9, which are method scoped. Rather than fight that, we’ll call gsub from C land using a CUSTOM patch.
