  • Mun v0.4.0 released
    4 projects | /r/rust_gamedev | 13 Dec 2022
    For those of you who haven’t heard of Mun before, Mun is an embeddable programming language empowering creation through iteration. The idea to create Mun originated out of frustration with the Lua dynamic scripting language and a desire to have similar hot reloading functionality available in Rust. As such, it’s not a direct competitor with Rust, but instead is intended to be used with Rust (or C/C++) as a host/embedded language pairing. Actually, Mun is completely written in Rust, building on similar crates as rust-analyzer and rustc. Its key features include:

  • You can't do that because I hate you
    9 projects | news.ycombinator.com | 28 Dec 2023
    The author provides very surface-level criticism of two Rust tools, but they don't look into why those choices were made.

    With about five minutes of my time, I found out:

    wrap_comments was introduced in 2019 [0]. There are bugs in the implementation (it breaks Markdown tables), so the option hasn't been marked as stable. Progress on the issue has been spotty.

    --no-merge-sources is not trivial to re-implement [1]. The author has already explained why the flag no longer works -- Cargo integrated the command, but not all of the flags. This commit [2] explains why this functionality was removed in the first place.

    Rust is open source, so the author of this blog post could improve the state of the software they care about by championing these issues. The --no-merge-sources error message even encourages you to open an issue, presumably so that the authors of Cargo can gauge the importance of certain flags/features.

    You could even do something much simpler, like adding a comment to the related issues mentioning that you ran into these rough edges and that it made your life a little worse, or with a workaround that you found.

    Alternatively, you can continue to write about how much free software sucks.

  • Let else will finally be formatted by rustfmt soon

    The new style still supports single line let-else, and there is a configuration parameter to make it be on one line also for longer lines.

    I’m not sure they are? I don’t mean this to criticize anybody on the project — I’m sure they have other things going on — but there are a whole bunch of open PRs without even a single comment.

    However since 4179 recent versions should merge configuration files. Not sure what the details / specifics are but if just ignoring the file entirely is not good enough you might give it its own directory and rustfmt.toml file and see if that works.

    Rustfmt is a tool that formats Rust code in compliance with style guidelines. Its name precisely reflects its purpose. To install rustfmt, you can run rustup component add rustfmt. Once installed, you can execute cargo fmt to format Rust code in your workspace. If you require further information, you can visit rustfmt’s GitHub repository.
