Template metaprogramming in the traditional sense becomes possible with the use of `token_fmt` and parse constructors:
```
char const* token_key, token_value;
char const* template = txt(
Code with {key value} to replace with token_values
...
);
char const* gen_code_str = token_fmt( template, num_tokens, token, ... );
Code <name> = parse_<function name>( gen_code_str );
```
## Code generation and modification
There are three provided interfaces:
* Builder
* Editor
* Scanner
Editor and Scanner are disabled by default, use GEN_FEATURE_EDITOR and GEN_FEATURE_SCANNER to enable them.
### Builder is a similar object to the jai language's string_builder.
* The purpose of it is to generate a file.
* A file is specified and opened for writting using the open( file_path) ) fucntion.
* The code is provided via print( code ) function will be seralized to its buffer.
* When all seralization is finished, use the write() comamnd to write the buffer to the file.
### Editor is for editing a series of files based on a set of requests provided to it.
* The purpose is to overrite a specific file, it places its contents in a buffer to scan.
* Requests are populated using the following interface:
* add : Add code.
* remove : Remove code.
* replace: Replace code.
All three have the same parameters with exception to remove which only has SymbolInfo and Policy:
* SymbolInfo:
Markers are
* File : The file the symbol resides in.
Leave null to indicate to search all files.
* Marker : #define symbol that indicates a location or following signature is valid to manipulate.
Leave null to indicate that the signature should only be used.
* Signature : Use a Code symbol to find a valid location to manipulate, can be further filtered with the marker.
Leave null to indicate that the marker should only be used.
* Policy : Additional policy info for completing the request (empty for now)
* Code : Code to inject if adding, or replace existing code with.
Additionally if GEN_FEATURE_EDITOR_REFACTOR is defined, refactor( file_path, specification_path ) wil be made available.
Refactor is based of the refactor library and uses its interface.
It will on call add a request to the queue to run the refactor script on the file.
### Scanner allows the user to generate Code ASTs by reading files.
* The purpose is to grab definitions to generate metadata or generate new code from these definitions.
* Requests are populated using the add( SymbolInfo, Policy ) function.
The symbol info is the same as the one used for the editor. So is the case with Policy.
The file will only be read from, no writting supported.
One great use case is for example: generating the single-header library for gencpp!
### Additional Info (Editor and Scanner)
When all requests have been populated, call process_requests().
It will provide an output of receipt data of the results when it completes.
Files may be added to the Editor and Scanner additionally with add_files( num, files ).
This is intended for when you have requests that are for multiple files.
Request queue in both Editor and Scanner are cleared once process_requests completes.
### Notes on multi-threading:
Its intended eventually for this library to support multi-threading at some point,
however for now it does not.
The following changes would have to be made:
* Setup static data accesss with fences if more than one thread will generate ASTs
* Make sure local peristent data of functions are also thread local.
* The builder should be done on a per-thread basis.
* Due to the design of the editor and scanner, it will most likely
be best to make each file a job to process request entries on.
Receipts should have an an array to store per thread.
They can be combined to the final reciepts array when all files have been processed.
For now single-threaded has a bunch of optimization that most likely have done to it and will be more than capable
for the majority of projects this thing is intended for. (IF you use this on Unreal... well your asking for it...)
### Notes on extending with whatever features you want
This library is very small, and you can easily extend it.
The untyped codes and builder/editor/scanner can be technically be used to circumvent
any sort of constrictions the library has with: modern c++, templates, macros, etc.
Typical use case is for getting define constants an old C/C++ library with the scanner:
Code parse_defines() can emit a custom code AST with Macro_Constant type.
Another would be getting preprocessor or template metaprogramming Codes from Unreal Engine definitions.
