I have added VMAR children support, so it should be user-friendly now.

I’ve added VMAR and VMO, but they still require more functionalities to become user-friendly. Anyway, racaOS is now supported to run as a libOS on Linux!

I am going to support LibOS! This will enable us to test our operating system on linux, and it avoids breaking unit tests.

We’ve added two kernel objects, process and channel. The next step will to implement more functions, and we will make use of kernel-hal tomorrow.

I turned back to rust. Now I am going to implement my design.

I’m trying really hard to parse ACPI tables. But the address of the first sdt is invalid for some unknown reasons.

Now we no longer need a semicolon after expressions like for and if!

The llvm backend is now more robust. More tests will be added in the future to ensure it works well. Now you can use continue and break freely!

Cara has break & continue now! But I think I need to wrap the creation of a basic block. The current version requires a lot of testing to avoid bugs.

Now you can pass functions as values! And you don’t need to worry if the compiler compiles the function several times.

Shipped this project!
This is a compiler which support multiple files and namespace! You can also compile to other platforms. It’s highly inspired by rustc.
We can build cara for other platforms now! And type inferring will be implemented tomorrow.

love your project!
I have added usize and isize, which involves the support of more targets. Now, in theory, you can build cara for more platforms.

To easily support typed AST, I refactored expressions, which allows analyzer to create a HashMap that stores all the type info.

After working really hard, I have finally made github actions work. Now we can build releases easily.

Cara has a lexer now! This improves the stability of parser, and will allow us to create procedural macros!

that’s so impressive :P
Now we support multiple files! I will refactor parser and analyzer next, then we can introduce procedural macros and a usable LSP!

Now we can access constants in the same namespaces easily, and further support shall be done tomorrow. Also, another analyzer which checks namespaces should be built.

After working hard, I have successfully fixed many bugs of the compiler, and we are now able to create functions in a struct, and access them like A::b! We will implement more features such as better namespaces later.

Cara has structure support now! But I haven’t used a lexer yet, because I don’t want to drop the parser written in peg I have now.

I have tried and tried, but the parser is still broken. Maybe I should create a lexer tomorrow, which should simplify the work.

I have finally implemented a good type checker, and I shall start OOP.

The basic structure of analyzer is built, and I will implement a full-featured analyzer in the next few days.

Now the symbol table is written in a separate crate, so that I don’t need to write so much duplicated code.

I have added type cast, which allows the followings:
int -> int
ptr -> ptr
int -> ptr
ptr -> int.
More shall be added in the next days of development.

Broke the ExpVisitor trait, since it’s too long. I think methods in visitor traits shall be classified better, and I will do it tomorrow.

Added prototypes. This allows cara to extern C functions like printf. Now we can print things freely.

Add while, loop and for blocks. Currently they requires ;. I would fix that tomorrow.
