Well i guess thats what you get for using mcp instead of just opening the article and reading it

You are somewhat right, I used tagging masks to differntiate between different types of atoms [1]. But yes, interning will be backed by a correct implementation of a hashmap with some collision handling in the future. [1]: https:/&#x2

I havent written a lot, but it needs to be fast so i can be motivated to program more by the fast iteration

Sadly that was one of the things I did benchmark, but didn't write down the results. I read a lot that naive switch is faster because the compiler knows how to optimise them better, but for my architecture and benchmarks the computed g

Most of them, jump tables work in rust, mmapping too. deferred numeric parsing, keeping allocations to a minimum, string slices, interning and inline hashing all work in rust, go, c, c++; you name it.

Several possible reasons: - parallelism - concurrent machine code gen - different optimisations for different runs, producing differing machine code order, etc

It wont work because gov has no interest in not knowing which service the user is trying to authenticate themself to, it is in its interest to connect these informations. We see exactly these attempts every 2-4 years in the eu parliament.

Hi, author here, I just added the JSON macro to omit the quotation escaping around object keys and strings: without JSON macro: char* j = "{ \"key\": [\"value1\", \"value2\"]}"; with JSON macro: char

Hi, author here, definitely, allocating elements while parsing is slow, especially calling realloc for each new element encountered, a growing array backed by an arena would be my go to if i had to overengineer this one.

Hi, author here, i use the 'type' field of the json_value struct, strings, object keys, object values and array members are allocated, i use this info for freeing the memory

It just mentions a loop, so id say for a loop without any content, it should be less than 50ms, but as the other commentor said, it depends on your hardware and a better measurement is to compare relatively

According to the documentation it evaluates by walking the ast, so yes, this is considered very slow. The readme also mentions 1 million loop iterations in 0.14s (140ms). Even my unoptimised naive lips like language [1] (also implemented vi

I feel like no other embedded scripting language will ever surpass lua. Neovim, roblox and all my projects that needed scripting support use lua, its my first choice.
