You would definitely need an identifier translation table:
"Dsymbols *" -> "Dsymbol[]"
Might as well just define ArrayBase etc
"NULL" -> "null"
Sure, but what about all the places 0 is used to mean NULL?
`//printf("...%d...", s)` -> `writef("...%s...", s)`
Why not just keep it as printf?
"#ifdef XIFDEFVERSION" + nested ifdefs + "#endif"
-> "version(XIFDEFVERSION) {" + nested {}'s + "}"
"#ifdef 0" -> "version(none)"
No luck, dmd source uses #ifdefs mid-declaration,
mid-statement, and
mid-expression (even mid-string-literal)
It also uses #ifs with complex conditions.
And don't forget no-args ctors, implicit calling of ctors,
stack allocated
classes, new keywords, narrowing integer conversions,
'virtual', pure
virtual function syntax, macros as expression aliases, string
literal
constness, the EXP_CANT_INTERPRET cast hack, macros,
namespaces, macros,
structs using inheritance, and of course more macros.
Every single one of these would have to be special-cased. If
you had a domain-specific language you could keep track of
whether you were mid-declaration, mid-statement, or
mid-string-literal. Half the stuff you special-case could
probably be applied to other C++ projects as well.
If this works, the benefits are just enormous. In fact, I
would actually like to "waste" my time trying to make this
work, but I'm going to need to ask a lot of questions because
my current programming skills are nowhere near the average
level of posters at this forum.
I would like a c++ lexer (with whitespace) to start with. Then
a discussion of parsers and emitters. Then a ton of questions
just on learning github and other basics.
I would also like the sanction of some of the more experienced
people here, saying it's at least worth a go, even if other
strategies are simultaneously pursued.
Something like this https://github.com/yebblies/magicport2 ?
Yes! I need to look it over more thoroughly, but I couldn't ask
for a better beginning. Can I trust that you'll be a willing part
of future discussions on this matter, even if only to play
Devil's Advocate?
