Regex which matches and returns a Uid, unescaped and with delimiters removed.
>>>
match uid "<12<34\\>56\\\\7>"
Just "12<34>56\\7"
generator :: Regex String Source
Regex which matches and returns a Uid generator, without delimiters and the leading prefix character.
>>>
match generator "<%>"
Just ""
>>>
match generator "<%mylabel>"
Just "mylabel"
escapeUid :: String -> String Source
Convert a Uid string into a form which can be put in a semantic document. It doesn't add delimiters.
>>>
escapeUid "1>2\\3"
"1\\>2\\\\3"
To prevent confusion, the above is the same as:
['1', '\\', '>', '2', '\\', '\\', '3']
unescapeUid :: String -> String Source
Convert a Uid as encoded in a semantic document into normal form, i.e. converting escape sequences to their target characters.
>>>
unescapeUid "1\\>2\\\\3"
"1>2\\3"
