BNFC.Backend.Common.StrUtils

Function that, given an input string, renders it either as a char (if it has legth 1) or a string. It should also excape characters correctly. The first returned value is the type of the string: either C for char or S for string. (used in the C printer to choose the right rendering function) e.g. >>> renderCharOrString "a" (C,"a") >>> renderCharOrString "abc" (S,""abc"") >>> renderCharOrString "'" (C,"\\'") >>> renderCharOrString ""\'" (S,""\"\\\'"")

Helper function that escapes characters in strings >>> escapeChars "\" "\\" >>> escapeChars """ "\"" >>> escapeChars "'" "\'"
