So actually, if someone wants to write an Ocaml function:
let textwrap x = ...
and perhaps test on some examples .. we can consider adding
it to the lexer, presumably applying to """ and ''' strings
but not r""" and r''' strings.
You should note that Felix allows:
val py =
" def f(x):\n"
" A = x + 1" 0x12 0x10
" try:\n"
" A = A + " (str 99) "\n"
" except:\n"
" print '" ("-" * 20) "'\n"
" print '" 63 "n Error'\n"
;
Although the concatenation is built-in to the compiler as part
of the macro time constant folding, it also works at run time:
var hello = "Hello";
var sp = " ";
var dot = ".";
var world = "World";
var eol = "\n";
print$ hello sp (dot * 4) sp world eol;
In fact .. there's no late optimisation of this:
that is, there is no 'C code' constant folder or
other optimisation of C code (there could be: C code
is generated using an AST)
