rustfmt VS book

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.

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.

Yacin Tmimi for actually implementing the bloody thing

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.

It seems there is an issue about this dating all the way back from 2018 but yet it still hasn't been fixed.

Presumably, https://github.com/rust-lang/rustfmt/pull/5690

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.

code must be formatted with rustfmt.

Yes, some cases are not yet supported (https://github.com/rust-lang/rustfmt/issues/4914).

My first port of call was to google learn rust which lead me to "the book". The book is a first steps guide written by the rust community for newbies (or Rustlings as they're called) to gain a 'solid grasp of the language'.

Before Prodzilla, I’d read 'The Book' a couple of times, and had made my way through Rustlings, but hadn’t yet built a serious project in Rust.

To answer your last question;

Start with the Rust book.

https://doc.rust-lang.org/book/

Then do Rustlings until the syntax becomes muscle memory.

Then join the Discord and start doing little projects.

You won’t get up to the proficiency of other languages as quickly in Rust. It takes longer. For me it’s taking a lot longer, but I enjoy it.

Before diving into these repositories, familiarize yourself with Rust and its development ecosystem. The official Rust book is an excellent resource for developers at all levels. Each repository has documentation on how to contribute, covering code style, issue tracking, and pull requests.

This is my third Rust book after the official book and Rust in Action. The other two books are great, but they were too theoretical for me. I'm a slow learner and had much trouble grokking Rust's features and idiosyncrasies. When I was done with these books, I was lost and unsure of what I could do.

It's the same reason everything digital and downloadable isn't free: there's a cost to create it and there's a value to it.

For a language developer to charge for a book about that language, I think that's a completely valid way to make some money off of their work.

Even the Rust book, "The Rust Programming Language" is available freely online [0], but also as a print and ebook for sale via NoStarchPress [1].

We use it to write docs in our company which are then compiled by GitHub Actions and published as GitHub Pages. The best example of a Book produced with mdBook is the Rust Lang book: https://doc.rust-lang.org/book/

I disagree. Words have meaning. 'Open source' means 'open source' in all contexts.

For comparison, https://doc.rust-lang.org/book/ is an open source book. A PDF with a CC license without a repo of the publishing artifacts is not an open source book. It's just a free book.

Disclaimer This tutorial is by no means to a complete guide. This is just to show you the basic way you can approach making a CLI and how to sort of go about making it. This article also presumes that you have a good enough knowledge of the rust language. If you don’t, I recommend you check out the official rust book. It is a very good resource for learning rust.
