Ah yes I understand now!
Tabs let you define how big you want each indent to be
…except when they don’t. Many common environments have a hardcoded tab size of 8, which is insanely big for using it for indentation.
Because other people might have restricted environment which might not suit their preference is not a good reason to level it down IMO.
Also, I think 9 is the best size for indent (matter of preference), do you think I should switch to space so everyone can enjoy this wonderful view I have ?
It’s not just “might”. Termux is pretty much the only good choice for programming on Android.

I think you should switch to an exorcist.
What’s your point ? You can use vim on termux and set the tabsize to whatever you want for example.
As an embedded software developer that does linux kernel drivers I’ve come to love the tab size 8 indentation level.
I’m paraphrasing: “if your indentation level gets too deep, it’s time to rethink/refactor your function.”
And with tab 8 you’ll notice it rather quick if your function does too much/unrelated stuff.
A function should be short and do one thing only, if possible. It also makes unit testing easier if that’s a requirement.
When you’re operating on such a low level of abstraction, it’s no wonder you don’t need deep nesting.
Oh, I’ve done my fair share of C++ and Python as well. But you got to agree with me that when you are on your fourth indented “if case” it’s time to step back and think about what you are trying to achieve. I mean it’s probably going to work, but probably also very hard to maintain that type of code.
What environment are you using that has a hardcoded tab size? I haven’t seen this since typewriters.
Some projects just use tabs as a compressed form of 8 spaces. But that is a sin. Use tab to mean “one indent level” and align with spaces if you need to. (the occasional ASCII art diagram)

- Termux
- SourceHut
- “View page source” in the browser
Termux
I think running tabs -N (where N is you preferred tab size) in the terminal should work. This is what I use in my zshrc on desktop.
SourceHut
Yup, they seem to be pretty opinionated here. If you look at the source there is just an inlined style with a single rule pre { tab-size: 8 }. I guess that is what you get when you use opinionated tools. The user’s browser isn’t right, my preference is right!
“View page source” in the browser
On Firefox this uses my default tab size of 4. But I guess changing this default isn’t user-friendly.
This is the biggest problem with tabs. Too many tools don’t let you adjust the size (or make it very difficult). This is the only reason I usually prefer spaces (only very slightly).
My dream solution is elastic tabstops and I’ve posted about it here before a few months ago. The problem with wanting elastic tabstops is that it seriously compounds the issue of “editors don’t properly support it”
This is a holy war that I will gladly fight again and again! I can’t believe that soft tabs are more popular, especially in python!
Tabs work fine, you aren’t allowed to mix, indentation must be consistent.
Actually I think you can technically mix. They have a “conversion factor”. But don’t, because then the code will look like crap on any other tab size (defeating the point of using tabs in the first place)
I think it would be better that each line needs to start with the exact same bytes to be considered within the same indent level. But I don’t think that is the decision Guido made.
That’s all well and good if everyone uses editors you can configure to a certain standard all the time. Then tabs all the way.
Unfortunately that’s not reality for everyone.
Honestly, what fucking editor are you using that doesn’t allow you to configure tab length? Wordpad?
I’ve always wondered why some people tout “forcing a consistent appearance across environments” as a pro for spaces. That’s a bad thing.
To be honest I’m surprised code format converters aren’t ubiquitous. Let the repo have it’s master format, enforced on commit. Then converters translate into each developer’s preferred standard dialect on checkout and back again on commit.
The consistent appearance thing is probably more about how mixing tabs (for indentation) and spaces (for alignment, eg in multi-line function definitions of calls) looks like complete crap if you change the tab width.
I think you have it backwards. If you use tabs for indentation and spaces for alignment it works great for any tab size.
It is when you use a tab just as a compressed representation of 8 spaces and use them for alignment as well that it goes to shit. (because you have made the sin of tab == 8 spaces instead of the correct tab = 1 indent level)
How does that work, and with which editor settings? If you simply set the tab width (tabstop) in vim, things go south.
Say you have a function definition one indent level in, then 22 characters of text. You more want to align the next line to that. How does that work in practice with tabs?
The obvious way with tabs and ts=4 would be 6 tabs and two spaces(one tab for the initial indent, the rest to match 22 characters). But then someone with ts=2 comes along and barely gets half way there, or someone with ts=8 who overshoots by a lot.
Using only tabs for indentation and only spaces for alignment will never result in crap alignment when adjusting tabstops because the alignment does not use tabs.
This is using both tabs and spaces for alignment.
--->func foo(int i,
--->---> int j);
Observe what adjusting the tabs does,
->func foo(int i,
->-> int j);
This uses only spaces for alignment,
--->func foo(int i,
---> int j);
When converted the alignment is maintained because the tabstops aren’t used for alignment, only for indentation.
->func foo(int i,
-> int j);
