> you've written an an ARM disassembler Here's my AArch64 disassembler work in progress: https://github.com/dlang/dmd/blob/master/compiler/src/dmd/ba... I add to it in tandem with writing the code generator. It helps flush out bugs in both by doing this. I.e. generate the instruction, the disassemble it and compare with what I thought it should be. It's quite a bit more complicated than the corresponding x86 disassembler: https://github.com/dlang/dmd/blob/master/compiler/src/dmd/ba...

Yup, dmd also has an error type: https://github.com/dlang/dmd/blob/master/compiler/src/dmd/mt...

P.S. The DFA I wrote for Datalight C still persists in the DMD D compiler: https://github.com/dlang/dmd/blob/master/compiler/src/dmd/ba...

Here's the pipeline spitting out the same error as on my macbook did. https://github.com/dlang/dmd/actions/runs/8023469412/job/219...

I added your code to the D test suite. It passes on all supported platforms, including Windows and OSX. I am at a loss why it isn't working for you. https://github.com/dlang/dmd/pull/16238

Not completely on topic (if you read TFA) but my favorite Git commit is by compiler badass and HN frequenter, where he checks in an entire C compiler to the D language repo: https://github.com/dlang/dmd/pull/12507 https://news.ycombinator.com/item?id=27102584

A new generated code alone is 4000 lines long [1]. The actual code added is just 2000 lines, and some are used to pay debts, I mean, to make a proper code generator. It is debatable whether that generator should count in the number of lines, since you can always write a generator in a simpler scripting language (for example, Rust uses Python to generate the `unicode-xid` crate). In any case however it is far less complex and, in my opinion, much smaller than the entire C parser proper. [1] https://github.com/dlang/dmd/pull/15307/files#diff-3677bcc89...

Thank you for the explanation. I agree that if one isn't going to enhance C, one is going to have to resort to these tools. C gets new features now and then. Why not add something incredibly useful, like the slice proposal? Instead, C23 got enhanced with the crazy Unicode identifiers. Richard Cattermole has been adding them to D's C support, requiring 6000 lines of code!! https://github.com/dlang/dmd/pull/15307 The entire C parser is 6000 lines of code: https://github.com/dlang/dmd/blob/master/compiler/src/dmd/cp...

D is completely opensource already (https://github.com/dlang/dmd). The "open" of OpenD is just ADR saying that OpenD will be more open to new language features than D has historically been.

The reference compiler, DMD, is open source: https://github.com/dlang/dmd But they don't accept just any Pull Request or features the community submits, understandably. There's a process called DIP for language improvements: https://github.com/dlang/DIPs/blob/master/DIPs/README.md However, by some accounts, it's really hard to get anything through. Given D already has so many features, I find that to be a good thing, to be honest, but not everyone agrees, of course.
