Hi,<br>
<br>
There have been discussions now and then about the preprocessor and<br>
how it would be better to get rid of it. As someone that has to parse<br>
and handle source files before they are preprocessed, I am very much<br>
affected by it -- with macros that can be anything, an raw Erlang file<br>
can look like pretty much anything. Even if the macros are in practice<br>
mostly well-behaved, using them as alternatives to inlining code<br>
creates problem when debugging, for example, because you can't step<br>
through a macro invocation.<br>
<br>
One of the main reasons that was presented for not being able to<br>
replace the preprocessor with something that works at the lexical<br>
level is that records would need to be first made first-class citizens<br>
(as frames or whatever). I don't understand why that is -- the<br>
preprocessor doesn't do anything with records, their expansion is done<br>
later, by the compiler. Could someone comment on that, please?<br>
<br>
Is this issue a "definitely no-no" for OTP, or would it be considered<br>
if we can come up with a solution that doesn't break anything?<br>
<br>
<aside><br>
Stepping through the code in the debugger is being thwarted even by<br>
the use of parse transforms. This could be handled by letting the<br>
debugger reconstruct the source it shows from the parsed<br>
representation and not from the source file.<br>
</aside><br>
<br>
best regards,<br>
Vlad<br>
