Interesting take. I prefer spaces because each piece of code that I see with tabs has an implicit tabsize you really need to have if you don't want the code to look ugly - especially if the person has been mixing tabs and spaces - and they usually do. Sometimes unadvertently.

When you remove all tabs at least everyone is on the same page.

To the actual problem raised by the article:

I have ADHD. Two spaces per indent makes it damn near impossible for me to scan code. My brain gets too distracted by the visual noise. Someone who’s visually impaired might bump their font size up really large, and need to scale up or down the amount of space per indent. Someone might just prefer it because…

I wonder if it could be possible to adjust the "indent number of spaces you see" in code editors. Code editors are able to figure out what are indents and what are not, so in theory it should be possible. Perhaps that would be an idea for a new feature?

Tabs let you define how big you want each indent to be, and spaces do not.

Spaces can too: Simply use more or less of them, to taste.

Then use four, or six, or eight, or 20. Hell, most code I've seen uses four spaces per indent anyway.

Surely there's an editor out there that will automatically display indent spaces as a tab character. Or failing that it seems like it would be rather trivial create a program to convert n spaces to tabs, and vice versa.

Nah, I'll keep on sticking with spaces or whatever the language's formatter uses. Ain't no way am I mixing tabs and spaces, will just stick with spaces.

Ah yes I understand now!

Original poster is right by all accounts, of course. Now, let's come up with exotic significant indentations.

function xyz(a, b):
|   var x = 2

|   if true:
|   |   do_something()
|   else:
|   |   do_something_else()

|   anyway()

Pro: Your editor no longer needs to implement indentation hints.

Con: Looks obstructive if not highlighted like an indentation hint.

Your turn.
