Hello,
It’s easy to recuperate the matched substring in replace and do something like:
julia> replace("foobar", r"b([a-z])r" => s"\1")
"fooa"
However I can’t pass the output to a function so for instance this:
julia> replace("foobar", r"b([a-z])r" => uppercase(s"\1"))
"foo\\1"
this works but is a bit silly with the double matching:
julia> rx = r"b([a-z])r"
julia> replace("foobar", rx => s -> uppercase(match(rx, s).captures[1])
"fooA"
is there an obvious way to do this better? generally what might be nice is to do something like:
replace("foobar", regex => myfun)
where the myfun would get access to the regex match and have access to fields like captures
myfun(m) = uppercase(m.captures[1])
Thanks!
