Write Ć in Ć

[tq-xyy]

I think it is cool.

[andreasbaumann]

Actually, this is a really nice idea: so cito could have bootstrapping backends when being transpiled to quite a lot of languages.

[pfusik]

Yes, that's the plan!

I'd love to have cito:

• without the dependency on .NET
• running right in your browser

I've made some progress already: added HashSet and Stack collections, refactored cito to avoid boxing.

[andreasbaumann]

Cool. :-)

As I wrote in discussion: before writing Ć in Ć , can make C#-> Ć transpiler. People which can much C# code will possibility convert it to Ć before convert to other languages.

[pfusik]

Current status: lexer fully ported to Ć, most of the AST and the parser ported to Ć.

[pfusik]

Current status: the AST and the parser ported to Ć, the semantic pass partially ported.

• without the dependency on .NET

Maybe using .NET NativeAOT is a simpler way to get rid of the dependency on .NET (it compiles C# to native binary code and does not need .NET dependency to run the compiled program).

• running right in your browser

.NET has an experimental NativeAOT-LLVM compiler to target the wasm platform.

[pfusik]

Yes, but a .NET NativeAOT binary is going to be tens of megabytes and slower than Ć transpiled to C++. Also, since Ć is about portability between programming languages, it just doesn't look good to rely on .NET for a cross-platform transpiler.

During the rewrite, I added several features to Ć. They will be useful in many other projects.

Current status:

• Semantic analysis ported - covered by "CiCheck" tests for Java and JavaScript.
• The remaining part are backends - started.

[pfusik]

Current status: all backends ported, but with some native C# blocks.

[pfusik]

Great news: we have cito in C++! It passes all the tests and runs much faster than the C# version.

Next steps:

• Test on macOS and Linux
• Add CI tests
• Continue porting to browser JavaScript
• Update the docs
• Release 3.0.0 with native binaries for Windows/macOS/Linux

Test on macOS and Linux

Works fine with gcc 13 on Fedora 38. xcode on macOS doesn't implement enough C++20. @pdelewski How to install gcc 13?

Add CI tests

GitHub Actions and Travis only support Ubuntu up to 22.04. I can't find gcc 13 or clang 16 packages for it.

Continue porting to browser JavaScript

make -j8 test CITO="node cito.js" passes all the tests. :)

[pdelewski]

@pfusik I was installing via brew install gcc 13 is the latest version

[epi]

@pfusik On Ubuntu 22.04 I built GCC 13 from sources, but that probably won't work in CI.

[pfusik]

sudo add-apt-repository -y ppa:ubuntu-toolchain-r/test
sudo apt install g++-13

[pfusik]

The language is now fully implemented in itself, except for I/O. Native binaries for Windows, macOS and Linux can be built with C++20 compilers. A release is coming soon. The transpiler also works in browser JavaScript. It will be present on the language website. And the C#-hosted transpiler continues to work, but is less performant than the C++ version.

I'd like to enable the transpilation to Java for an IntelliJ IDEA plugin. It will probably need small changes in the Java backend (Java doesn't support constant case with a when clause).

You can now run fut in your browser: https://fusion-lang.org 4K monitor strongly recommended.
