Have you, like, seen the release notes for 0.9.0?

> Zig still can't proper handle UTF-8 strings [1] in 2022

There's plenty of discussion on the subject in basically every HN thread about Zig: the stdlib has some utf8 and wtf validation code, ziglyph implements the full unicode spec.

https://github.com/jecolon/ziglyph

You might not like how it's done, but its factually incorrect to state that Zig can't handle unicode.

> In a `recent` interview[2], he claims that Zig is faster than C and Rust, but he refers to extremely short benchmarking that has almost no value in the real world.

From my reddit reply to this same topic:

This podcast interview might not be the best showcase of the practical implications of Zig's take on safety and performance. If you want something with more meat, I highly recommend Andrew's recent talk from Handmade Seattle, where he shows the work being done on the Zig self-hosted compiler.

Lots of bit fiddling that can't be fully proven safe statically, but then you get a compiler capable of compiling Zig code stupidly fast, and that's even without factoring in incremental compilation with in-place binary patching, with which we're aiming for sub-millisecond rebuilds of arbitrarily large projects.

> The ecosystem for zig is insignificant now and a stable release would help the language.

I hope you don't mind if we don't take this advice, given the overall tone of your post.

For Unicode text processing you can take a look at Ziglyph https://github.com/jecolon/ziglyph and for a sample UTF-8 string structure, Zigstr https://github.com/jecolon/zigstr . (bias alert: I'm the author of both. :^D )

Agreed, and Zig also has a lib for that as well:

Yes, sorry about that - I omitted a bit of that information for brevity.

If you want to play with allkeys.txt (which is by far much more sequential, simpler data than UnicodeData.txt) then you only need to remove the non-NFD strings (since the Unicode Collation Algorithm's first step requires you to decompose the string's code points to canonical NFD form), that removes ~2,000 entries.

The full file parser code, which strips those out and other useless information like comments and version information can be found here: https://github.com/jecolon/ziglyph/blob/main/src/collator/Al...

If you want to play around with UnicodeData.txt (which is less sequential, more complex data) then only two fields are used (the code point and decomposition field), and only records where the second field is not empty (the full decomposition type name in angle brackets is not needed, only whether it is or is not there is important.)

The full parser code for that file can be found here: https://github.com/jecolon/ziglyph/blob/main/src/normalizer/...

Hope that helps!

Here's the pipeline spitting out the same error as on my macbook did.

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 (which can be alternatively written in a simpler scripting langauge). In any case it is never comparable to the entier C parser proper.

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 feature, I find that to be a good thing , to be honest, by not everyone agrees, of course.
