xixanta: add context from macro expansions

2026-02-02T18:56:21Z

The way macro expansions work is that the evaluated bundles replace the current node, but this throws away the context of the line, the source, etc. from the original line of code. Add a stack that is pushed/popped when expanding macros, and are then cloned for each pending node and error. This way, errors have full context of the original code and can display backtraces for macro expansion. Signed-off-by: Miquel Sabaté Solà

Drop lazy_static dependency

2025-01-22T21:38:33Z

Apparently the standard library had LazyLock which is enough for what I wanted to achieve with lazy_static. Signed-off-by: Miquel Sabaté Solà

Add support for cfg files

2025-01-13T15:15:06Z

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

Rename SourceInfo::working_directory to directory

2025-01-09T15:32:34Z

Also documented the struct as it is exported. Signed-off-by: Miquel Sabaté Solà

Merge all error types into a single one

2025-01-09T15:30:01Z

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

Implement the .include statement

2025-01-09T15:01:39Z

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 labels

2024-12-16T15:10:15Z

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 parser

2024-12-12T06:46:17Z

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. Signed-off-by: Miquel Sabaté Solà

Re-work the parser from scratch

2024-12-12T06:41:30Z

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 mapping

2024-12-12T06:31:52Z

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
