rapidyaml VS dmd

Interesting, I hadn't come across extism before. How hard would it be to package https://github.com/biojppm/rapidyaml in this way? (And do you have a extism for dummies guide?)

The inability, or brittleness, to embed NUL bytes into the string, for once. Zeroed bytes can be valid as an internal bytes of a longer encoded character. And the inefficiency of tempting every caller to rederive the string length on every use, leading to such bugs as quadratic parsing behavior with sscanf. The extra register for an explicit length is a very minute price to pay compared to that.

Although you still have the other problem of sscanf, where read times can become quadratic.

You are really simplifying that issue. A lot of it has to be how the implementation of sscanf works and it's super easy to abuse by complete accident when a lot of data needs to be read and parsed to correct values. See more here: https://github.com/biojppm/rapidyaml/issues/40

Leading to eye-rolling problems like these: https://github.com/biojppm/rapidyaml/issues/40

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.
