Tabs are 8 characters, and thus indentations are also 8 characters. There are heretic movements that try to make indentations 4 (or even 2!) characters deep, and that is akin to trying to define the value of PI to be 3.
I am in love with this awsome document; I love its guidelines, and coding conventions.
However, when Rust was introduced into the kernel, they butchered these beautiful guidelines, I know it’s hard to look at such heretic actions, but you have to see this:
The default settings of
rustfmtare used. This means the idiomatic Rust style is followed. For instance, 4 spaces are used for indentation rather than tabs.
How can this even relate to the ideology of the first document? I am deeply saddened by these new rules.
I know this is “The Rust experiment”, but this must be fixed before it’s too late! This has to reach someone.
A counter-argument might be:
The code should be formatted using
rustfmt. In this way, a person contributing from time to time to the kernel does not need to learn and remember one more style guide. More importantly, reviewers and maintainers do not need to spend time pointing out style issues anymore, and thus less patch roundtrips may be needed to land a change.
And to that I say that rustfmt is configurable per project, and if it isn’t, then it has to be. Doesn’t something like .editorconfig exist?
We are not stuck to DEC VT100 terminals anymore. It’s okay to have 100 columns of code. And wasting 10% of that space for each indentation? What are you smoking?
As I said before, this standard is older than C itself, and the kernel’s been using it for decades, I shouldn’t have to explain it. Long tabs and short lines boost readability, and restricting indentation to 3 solves the problem. Read my reply to 1rre@discuss.tchncs.de for more context.
Also
rustfmtdidn’t move the string inprintln!("a very long string slice with a static lifetime");to a new line even when it exceeded a 100 columns, I should seek a solution.Note: The actual string I used was way longer than that.
