Recognize undos map

[tdymel]

I tried to match a format like string like this:
"This is a {{{arg}}} literal". I wanted it to replace the escaped character "{" using map, such that my end result would be:
"This is a {", "arg", "} literal"

Below the code I use to parse the literal, ie. "This is a {{" -> "This is a {"

recognize(many1(alt((
        map(tag("{{"), |_| "{"),
        map(tag("}}"), |_| "}"),
        is_not("{"),
    )))).parse(input);

The part without recognize would output: ["This is a ", "{"]
Recognize turns it into "This is a {{"

This is due to how recognize works. From the docs:

If the child parser was successful, return the consumed input as produced value.

This means that it will only return the input, unmodified.
If you want to match the string with curly braces escaped properly, you have 2 main choices:

1. Replace those brackets in the string afterwards (i.e. with "{{".replace("{{", "{"))
2. Reconstruct the string from the parsers (i.e. by using either a Write / build pattern or concatenating strings)
