https://issues.dlang.org/show_bug.cgi?id=5051 Andrei Alexandrescu changed: What|Removed |Added Keywords||bootcamp CC||and...@erdani.com --- Comment #10 from Andrei Alexandrescu --- That would be an interesting project. I'm envisioning it as a standalone program called e.g. "dlower" that lowers D code into a smaller subset of D. Possible flags for that program: --expand-mixins = expand all possible mixins in the code --lookup = execute lookup on all symbols and write the full symbol, e.g. writeln becomes .std.stdio.writeln --operators = explicitate all user-defined operators, e.g. a + b becomes a.opBinary!"+"(b) --omit-function-bodies = do not output function bodies, .di style --specialize-templates = write specialized versions for all templates used within the module (this is likely to be tricky) --scope = lower all scope statements into try statements --foreach = lower all foreach statements into for statements --explicit-import = specify the exact symbols needed for each import statement (which means: if no symbols, the import is redundant - easy to mark as a warning by a subsequent tool) --static-if = evaluate all static ifs possible (this mostly makes sense if --specialize-templates is also present) --versions = lower code using version(), i.e. make the unused branch disappear --omit-comments = make all comments disappear --omit-nondoc-comments = make only non-documentation comments disappear --ctfe = evaluate all possible CTFEs (tricky) The tool should generate compilable D code with the same semantics as the input and #line directives pointing to the input. Such a tool would make possible a bunch of others. I'll talk to the graduate students, maybe someone will take this. --

Not quite preprocessed D code per se, but close enough for debugging purposes. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

After compilation, you could look them up, but even better, you can single step through the code with a debugger (at least, if there are line feeds in the mixin). Another benefit: source line numbers in mixins do not overlap with the source code after the mixin anymore, but the patch was not good enough to show the place of instantiation in an error message. If there is interest, I can dig it up and create a diff to current svn. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

Agreed, I actually use this a lot when debugging backend bugs.
What I do is modify FuncDeclaration::toObjFile() in glue.c.
To do it properly would require a (fairly simple) pass over the syntax tree,
but the function case one is the most important by far. As you can see, it's
very simple.
Incidentally, when properly implemented, this feature would bring us much of
the way towards having a C backend.
//printf("'%s' is SCfastpar\n",sp->Sident);
}
}
}
+ if (!parent->isDeclaration()) {
+ printf("%s ", ((TypeFunction *)(func->type))->next->toChars());
+ printf("%s(%s)\n{\n %s}\n\n", func->toChars(),
+parameters?parameters->toChars() : "",
+func->fbody->toChars());
+ }
if (func->fbody)
{ block *b;
Blockx bx;
Statement *sbody;
localgot = NULL;
sbody = func->fbody;
