    Ahh, very interesting, thanks for sharing! Do you have any thoughts around why that is? I presume that's due to Oniguruma supporting a much broader feature set and something like fancy-regexp's approach with mixing a backtracking VM and NFA implementation for simple queries would be needed for better perf? (I am aware you played a role in that) [1]

    I have been playing around with regex parsing through building parsers through parser combinators at runtime recently, no clue how it will perform in practice yet (structuring parser generators at runtime is challenging in general in low-level languages) but maybe that could pan out and lead to an interesting way to support broader sets of regex syntaxes like POSIX in a relatively straightforward and performant way.

    Not an expert but fancy regex is a Rust library that uses a hybrid approach to detect whether a sub expression contains backtracking and delegates to the appropriate engine.

    I started using just [0] on my projects and have been very happy so far. It is very similar to make but focused on commands rather than build outputs.

    Define your recipes and then you can compose them as needed.

    Welp there is absolute chaos in that thread -- guess it's not an April Fools joke.

    I wonder if relying on CI for anything other than provisioning machines is a mistake -- maybe we should have never moved from doing things from local scripts written in $LANGUAGE.

    That said, I'm probably biased since I'm a massive fan of things like `make` and more appropriately for the current age, `just`[0]

  • Using Make – writing less Makefile
    6 projects | news.ycombinator.com | 26 Dec 2023
    Your coworker's experience is more principled: Make is a mediocre tool for executing commands. It wasn't ever designed for that. Although it is pretty common to see what you are mentioning in projects because it doesn't require installing a dependency.

    For a repo where an easy to install (single binary) dependency is a non-issue, consider using just. [1] You get `just -l` where you can see all the command available, the ability to use different languages, and overall simpler command writing.

    This is fantastic, but I'd say that this solution is somewhat in response to this open issue from 2019:

    I really wish just was included as a package in distributions.

  • Sharing Saturday #496
    6 projects | /r/roguelikedev | 8 Dec 2023
    So far, I didn't work on new features at all but on stabilizing the ground for further development: 1. CMake lists and modules were rewritten a lot, now managing builds and their configurations is much lesser pain. 2. Brought in Justfile for regular tasks, and it's great, no less. 3. Linters, formatters, analyzers for almost all the code (except for Janet for now, as because of it being a niche and young technology, it didn't get enough attention yet). 4. ECS stub. Now runtime class doesn't look like a god object. 5. Started writing unit tests which didn't happen with my personal projects before and maybe indicates how serious am I about this one :D 6. Some of previously hardcoded data has been moved to INI files. Now, if I release the game in 10 years, and in 10 more years some eccentric person decides to make a variant of it, it will be slightly simpler.
