rapidyaml VS ctl

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

C Container Template Library (CTL)

I guess something like that may exist but it can be done with the preprocessor alone. See https://github.com/tylov/STC or https://github.com/glouw/ctl

I assume you refer to that two of the letters match with STL or STD, right? Even if they are not related to C at all. I assume STB, CTL, are not acceptable for you either?

The standard C library lacks any kind of containers (vectors, hash tables etc.) so the first thing would be to find one you like. For example, the C Template Library is a nice one: https://github.com/glouw/ctl

While I agree the common pattern is to use void*/dynamic dispatch, this is not necessary. E.g., https://github.com/glouw/ctl/ or https://github.com/c-blake/bst show a couple ways to have generic code statically specialized in regular old C.

The template instantiation is rewritten and is now similar to how glouw CTL library does it. STC no longer contains long macros for generating the templated code.

define type macros before #including the implementation. (intrusive) This is how https://github.com/glouw/ctl does it. The good: type-safety. no casting, clear error messages. Somewhat clumsy to have to individual #includes for each container type instantiation of the same container.
