Made the parse definitions for variable, typedef, using more complete.
Fixed issues seen with expression token parsing Moved array expression parsing outside of type parsing. Its only done with variable, typdef, and using declarations. Added parsing of attributes, I'm going to make them separate from the regular specifiers as they are complicated.

|
||||
|
||||
Another would be getting preprocessor or template metaprogramming Codes from Unreal Engine definitions, etc.
|
||||
|
||||
## Why
|
||||
|
||||
Macros in c/c++ are usually painful to debug, and templates can be unless your on a monsterous IDE (and even then fail often).
|
||||
|
||||
Templates also have a heavy cost to compile-times due to their recursive nature of expansion if complex code is getting generated, or if heavy type checking system is used (assertsion require expansion, etc).
|
||||
|
||||
Unfortunately most programming langauges opt the approach of internally processing the generated code immediately within the AST or not expose it to the user in a nice way to even introspect as a text file.
|
||||
|
||||
Stage metaprogramming doesn't have this problem, since its entire purpose is to create those generated files that the final program will reference instead.
|
||||
|
||||
This is technically what the macro preprocessor does in a basic form, however a proper metaprogram for generation is easier to deal with for more complex generation.
|
||||
|
||||
The drawback naturally is generation functions, at face value, are harder to grasp than something following a template pattern (for simple generation). This drawback becomes less valid the more complex the code generation becomes.
|
||||
|
||||
Thus a rule of thumb is if its a simple definition you can get away with just the preprocessor `#define`, or if the templates being used don't break the debugger or your compile times, this is most likely not needed.
|
||||
|
||||
However, if:
|
||||
|
||||
* Compile time complexity becomes large.
|
||||
* You enjoy actually *seeing* the generated code instead of just the error symbols or the pdb symbols.
|
||||
* You value your debugging expereince, and would like to debug your metaprogram, without having to step through the debug version of the compiler (if you even can)
|
||||
* Want to roll your own reflection system
|
||||
* Want to maintain a series of libraries for internal use, but don't want to deal with manual merging as often when they update.
|
||||
* Want to create tailored headers for your code or for your libraries since you usually don't need the majority of the code within them.
|
||||
* You just dislike metaprogramming with template expansion
|
||||
|
||||
Then this might help you boostrap a toolset todo so.
