Summary: problem with '"' and 7F on EBCDIC plattforms
Initial Comment:
Hello Peter,
first on:
I only recently discovered re2c in the web. It's a great tool that provides
all the things I've been missing when using flex.
I found out a little problem when using the generated code on ebcdic-platforms.
re2c produces the following code in a switch-statement:
switch(yych)
{
...
case '"':
...
case 0x07F:
...
}
this code can not be compiled on EBCDIC-platforms, because there the
code of '"' is actually 0x07F. So the compiler complains about duplicate
case-labels.
I temporarily fixed the problem in my version of re2c by changing prtChOrHex in
dfa.cc so that it always prints only the Hex-Value like:
void prtChOrHex(std::ostream& o, uint c, bool useTalx)
{
int oc = (int)(re2c::wFlag || !useTalx ? c : re2c::talx[c]);
//
// if ((oc < 256) && isprint(oc))
// {
// o << '\'';
// prtCh(o, oc);
// o << '\'';
// }
// else
{
prtHex(o, c);
}
}
Now it is compiling and the result of the code-genration should accept the same
expressions.
Many Greetings
Thomas
