is it not common to write compilers for languages in the language being compiled itself? rust does this i think?

note that as others have said, "compiled" is a stretch, but nevertheless...

Programs that are less than full compilers in some sense can be bootstrapped.

For instance, this compiler for a pattern matching notation has parts of it implementation using the notation itself:

https://www.kylheku.com/cgit/txr/tree/stdlib/match.tl

Some pattern matching occurs in the function match-case-to-casequal. This is why it is preceded by a dummy implementation of non-triv-pat-p, a function needed by the pattern matching logic for classifying whether a pattern is trivial or not; it has to be defined so that the if-match and other macros in the following function can expand. The sub just says every pattern is nontrivial, a conservative guess.

non-triv-pat-p is later redefined. And it uses match-case! So the pattern matcher has bootstrapped this function: a fundamental pattern classification function in the pattern matcher is written using pattern matching. Because of the way the file is staged, with the stub initial implementation of that function, this is all boostrapped in a single pass.

> Even a bit of support for Godot's C#( help them get it working on web), would be great. They did that. https://godotengine.org/article/introducing-csharp-godot/ At least some initial grant to get it started. Getting C# working on web would be an amazing. It is already on the roadmap but some sponsorship would help tremendously for sure.

Ok. Credit where credit is due, but considering the sheer value of having the next general of programmers comfortable with .net, Microsoft *should* chip in more.

Hasn't Microsoft largely hitched their horse to Go these days, though (not just this project)? They even maintain their own Go compiler: https://github.com/microsoft/go

It is a huge company. They can do more than one thing. C#/.NET certainly isn't dead, but I'm not sure they really care if you do use it like they once did. It's there if you find it useful. If not, that's cool too.

This is great news. We actually use esbuild most of the time to transpile TS files because tsc is so slow (and only run tsc in CI/CD pipelines). Coincidentally, esbuild is also golang

Hi folks, Daniel Rosenwasser from the TypeScript team here. We're obviously very excited to announce this! RyanCavanaugh (our dev lead) and I are around to answer any quick questions you might have. You can also tune in to the Discord AMA mentioned in the blog this upcoming Thursday.

Is 10x a starting point or could we expect even more improvements in the future?

Hi Daniel! What's your stance on support for yarn pnp?

pnp is still very cool, and it would be great if we can find a better API story that works well with pnp!

Also, this is surprising because this was presented and led by Anders Hejlsberg, who is the creator of both C# and Typescript. If anyone should have picked C# it would be him.

Hejlsberg seemed quite negative when it came to cross platform AOT compiled C# in several comments he's made, hinting at problems with both performance and maturity on certain platforms.

Projects like this are needed to improve C#'s cross platform AOT. Missed opportunity IMO.

This is not accusatory, but do you write your comments with AI? I checked your profile and someone else had the same question a few days ago. It's the persistent structure of "it isn't X – it's Y" with the em dash (– not -) that makes me wonder this. Nothing to add to your comment otherwise, sorry.

This is definitely AI, repetitive and reads in style of a marketing copy / sensational report.

They're not "definitely" an AI. Sounds like a normal Go enthusiast to me.

Dumb question: is this a 10x speed up in the run-time of TypeScript ... or just the build tooling? And if it's run-time, can we expect browsers to replace V8 with this Go library? (I realize this is a noob/naive question - apologies)

There is no Typescript runtime, it's just a transpiler.

Even though I have my considerations regarding Go, I love that they picked Go instead of the fashion to go Rust that seems to be the norm now. A compiled managed language is much better approach for userspace applications. Pity that they didn't go with AOT compiled .NET, though.

It's not just a pity, it's very surprising. In my eyes Go is a direct competitor of C#. Whenever you pick Go for a project, C# should have been a serious consideration. Hejlsberg designed C# and that a team that he's an authority figure in would opt to use Go, a language which frankly I would not consider to build a compiler in is astounding. Not saying that in a judgemental way, I'm just genuinely surprised. What do…

C# has become a poor jack of all trades, trying to be Java, Go and F# at the same time and actually being a shity poor version of all of them. On top of that .NET has become a very enterprisey bloatware. In all honesty, I'm not surprised that they went with Go, as it has a clear identity, a clear use-case which it caters for extremely well and doesn't lose focus with trying to be too many other unrelated things at the same time.

Maybe it's time to stop eating everything that Microsoft sales folks/evangelists spoon feed you and wake up to the fact that only because people paid by Microsoft to roll the drum about Microsoft products telling you that .NET and C# is oh so good and the best in everything, maybe it's not actually that credible?

Look at the hard facts. Every single product which Microsoft has built that actually matters (e.g. all their Azure CNCF stuff, Dapr, now this) is using non Microsoft languages and technologies.

You won't see Blazor being used by Microsoft or the 73rd reinvention of ASP.NET Core MVC Minimal APIs Razor Pages Hocus Pocus WCF XAML Enterprise (TM) for anything mission critical.

Do we need to have these conversations weekly?

I wouldn't be asking if there wasn't a visceral reaction from Rust devs. I must have missed previous discussions on other threads.

Is this visceral reaction in the room with us now?

Edit: I have reached the bottom of the thread and still have not seen this visceral reaction mentioned by the OP.
