Yesterday, I shared some spicy takes. A few were particularly controversial—most notably, that I correct Gif the correct way (with a soft G)—but I also got a lot of emails asking me to elaborate on a few of them. Today, I wanted to talk about how tabs are objectively better than spaces. This won’t t...
You're viewing a single thread.
Tabs for indent, spaces for alignment. This is the way, I can't believe people are still fighting that ?
Anything for indent (barely matters, as long as the editor forces it to stay consistent), and fuck alignment, just put things on a new line.
struct Ident arr = [ { .id = 0, .name = "Bob", .pubkey = "", .privkey = "" }, { .id = 1, .name = "Alice", .pubkey = "", .privkey = "" } ];Not like that, lol
Just saying, instead of this monstrosity
CreateOrderRequest(user, productDetails, pricingCalculator, order => order.internalNumber)Just use
CreateOrderRequest( user, ...Putting the first argument on a separate line.
Same if you have an
ifusing a bunch ofand(one condition per line, first one on a new line instead of same line as theif) and similar situations.People seem to have a real issue with using new lines and I've never quite understod why.
It feels like a lot of those people are using notepad like applications instead of coding focused ones with collapsible regions etc.
When I talk about alignment it's not about function arguments, but values, "=" signs and such. You simply cannot use tabs for that because alignment must be fixed and indentation independent:
CreateOrderRequest( user, productDetails => order.detail, pricingCalculator => DEFAULT_CALCULATOR, order => order.internalNumber)I normally avoid that too, I find it hurts readability more than helps, plus a proper IDE will separate it with color anyway.
But yeah, the newline comment doesn't apply to this.
To each their own indeed. But my rule of thumb is: only use tabs when there's no other character before it (aka, start of line).
The emacs wiki agrees and has the correct take on this: https://www.emacswiki.org/emacs/SmartTabs
It seems like this basic guideline, tabs to indent and spaces to align, solves the problem for everyone. It doesn’t matter what your tab width is, it’ll look “right” regardless.
This kind of "manual" alignment should be avoided for many reasons including the fact that adding/removing/changing of one parameter here may force you to modify multiple lines which on it's own is annoying but this will also show up in the diff during review making it harder to grep what was actually changed.
I personally favor code readability over patch readability. But I reckon this is a matter of preference so I can understand how you might not like that.
Yeah I agree I don’t find alignment very useful. It’s more work for dubious benefit, and god forbid you change one of the lines.
The way god indented.
I almost scrolled past this one
seconded on not aligning things. its the whole source of the problem in the first place and doesnt even serve a purpose
It does help with reducing thrashing between edits in git diffs. Or rather, opinionated autoformatters do, which is the only reason I bother with alignment.
I used to think this way, at least when writing C++. But it's objectively harder to do and convince other people to follow, especially if they can't be bothered to change their environment to display tabs and spaces differently. It's a losing battle so now I just do spaces when working with other people
Always do spaces, because you can never trust how someone else has their tab configured.
How is this even a debate anymore. I thought we all agreed on this years ago.

Why on earth would I care how someone else has their editor configured? It's none of my business, and none of yours either.
Because other people are fucking morons and their editor doesn't have visible whitespace enabled - or it does but they don't give a shit.
Therefore these fucking morons have anywhere between 2 and 8 spaces-per-tab configured and will happily mash the tab key however many times is convenient for them to align their code or comments because they don't understand shit about fuck when it comes to alignement (or they don't care). Now I open their file and everything is predictably misaligned. Spaces and tabs are mixed from one line to the next, and in particularly egregious cases no tab width I can locally set on the file will make it readable because multiple different morons used different tab widths to align with tabs - sometimes within the same goddamn function or comment.
Have you ever tried to read an important technical diagram in ASCII art aligned with tabs by different people with different IDE settings? Because I have. Emphasis on tried.

This is a solved problem: Enforce linting before committing using something like Git Hooks / Husky.

No, because we live in the present and use proper tools for diagrams. SVG diagrams tend to be common nowadays. I'm aware you can't read them raw, but realistically the intersection between people who need to read important technical diagrams and people who don't have access to a web browser is vanishingly small (dare I say nonexistent?)
Tell me you develop with modern languages without telling me you develop with modern languages.
Try linting perl, or bash.
Like yeah if you work on a modern JS/Python/C# project, whatever, whitespace is going to be autoformatted, so the tabs vs spaces debate does not matter AT ALL.

You say this like it's a bad thing?
Try linting perl, or bash.
If you're already writing Perl/Bash scripts then it would probably not take you long to write a git hook to check the beginning of each line of source to check if there's a space or a tab character and preventing the commit if the wrong one is found. Crude and far from perfect, but still better than nothing.

It does though. If you read the original article then you'd know that the advantage of tabs is that everyone can choose exactly how deep their tabstops are, which is an objective benefit over spaces.
It's not wrong to work with modern languages, but don't pretend that you have the answer to the debate if you don't work in a field where it applies.
Linting bash/perl is a TERRIBLE idea. Consider the following, extremely common piece of code (perl has equivalent syntax as well):
#!/bin/bash cat > testfile < < EOF test1 test2 EOF(lol lemmy bug found, can't write the actual "left angled bracket - left angled bracket" syntax, it somehow truncates the comment)
OTOH if you use a modern auto-formattable language, then you can auto-format to tabs with a git hook or IDE plugin (and back for committing) if you want, so the debate doesn't matter in that case. It goes both ways.
I've yet to find tooling that supports this. Clang format has a setting that looks like it does it, but actually does something else. If I have to press the spacebar a bunch of times each time I add an argument to a function, that's a pain, and it's a bigger pain to convince the people I'm working with that that pain's less bad than using spaces everywhere and having the IDE deal with it.
Until the people making editors and auto formatters acknowledge that the obvious most sensible whitespace style is even a thing, I'm forced to do something else and be really grumpy about it.
I understand your point of view. Personally I either copy the previous line and replace the arguments there, or insert X number of space using the repetition feature of my editor. It also has a feature that will align multiple cursors together with the "farthest" one using space, which is a killer feature for me! (See this presentation video @1:40).
It's hard to do this consistently (especially in a team) because people might (and statistically in a large enough project, will) use the tab key for alignment since it's faster than pressing space, or just be confused about what whitespace is tabs and what is space. Just using space everywhere is idiot proof and requires no work to micromanage. The only way to use tabs is to not align at all.
And this is why language servers and formatters are so critical.
I agree that it's hard, but not impossible. This usually boils down to how Nazi people are when merging code. In a corporate environment, nobody gives a damn so yeah you gotta use whatever you want because there are already different indentation systems within the same file anyway :)
But hey, you gotta live by the changes you want to see happen, so I personally put a lot of effort in formatting my code regardless.
