* Add support for cfg filesMiquel Sabaté Solà2025-01-131-0/+1
| | | | | | | | In order to make tools like `xa65` work seamlessly with existing configurations, allow this format too instead of making developers switch to a new file with TOML syntax. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Rename SourceInfo::working_directory to directoryMiquel Sabaté Solà2025-01-091-2/+6
| | | | | | Also documented the struct as it is exported. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Merge all error types into a single oneMiquel Sabaté Solà2025-01-091-1/+51
| | | | | | | | They started with good intentions, but in the end they were all pretty much alike. Hence, it makes sense to simplify everything and provide a single struct. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Implement the .include statementMiquel Sabaté Solà2025-01-091-0/+15
| | | | | | | | | | | | | | This needed some heavy lifting when it comes to how files were located. This means that statements like .include/.incbin now take into consideration a new list made out of SourceInfo, which holds enough information to translate from which file a node comes from. This has also been added into errors, so they are more informative on what went wrong. In order to tests this, besides all the regular unit tests, a new e2e test has been added.

* Fix the mapping of addresses on labelsMiquel Sabaté Solà2024-12-161-2/+38
| | | | | | | | | | | | | | | | | There was a big missunderstanding on how things were to be laid out in the end file, and so it was needed to create a proper understanding on what's a Mapping and what's a Segment. These turned out to be fundamental concepts that I failed to grok up until this commit. Hence, this commit re-arranges completely how variables and labels are stored in the Context, and how these objects can then be translated into bundles that can be spit out to the caller. This commit, besides introducing the new Mapping struct, also introduced a more general Object, which abstracts things from the Bundle struct, and allows us to pass certain metadata about the bundle at hand.

* Adapt the assembler to the changes on the parserMiquel Sabaté Solà2024-12-121-6/+4
| | | | | | | | | | | As of 184c39579227 ("Re-work the parser from scratch") the parser has a proper AST, and the assembler has to traverse it accordingly. Moreover, the assembler has been stripped from a lot of unneeded memory allocations and it's overall more keen on using mere references when possible.

* Re-work the parser from scratchMiquel Sabaté Solà2024-12-121-0/+1
| | | | | | | | | | | | | The initial implementation was incredibly naive on how complex an assembler can actually be. Because of this, it never bothered to define and produce a proper AST, and hence it was overall extremely fragile on (not so) corner cases. This commit re-writes everything from scratch for the parser, and it should really be the last fundamental change to the parser other than minor additions/features here and there.

* Add the notion of mappingMiquel Sabaté Solà2024-12-121-0/+1
| | | | | | | Mappings and segments are fundamental blocks on how code is distributed both on the actual ROM File and in the memory layout. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Initial commitMiquel Sabaté Solà2024-12-121-0/+10
A lot is missing and there is a long road ahead to make the assembler even work. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
