Hard tabs make "pretty/readable indent" formatting difficult too.

If you want to line up certain arguments across lines, you just can't because you're forced to an unknown width of alignment chosen by the reader. So, all your code will just be indents that ignore the specific visual alignment intentions of the author, and that reduces readability and understandability in multi-person teams (and programming is a team sport, not a one-person-does-it-all game).

That's alignment not indentation. AFAIK gofmt uses spaces for vertical alignment

But, that's arguing two points, right? That's like saying ASCII has 8 built in non-visual field separators, so people should use those instead of CSV/TSV for text tables.

Sure, it's technically the right distinction, but it's not practical in any reality in which we live.

Trying to say "alignment" is distinct from "indent" and that tabs and spaces can be mixed depending on your intention is just crazy talk.

The only place tabs should be used is in Makefiles, and Makefiles should be autogenerated by CMake these days, never written by hand.

No?

It's not practical to do by hand (because most people can't be arsed to configure their editor to do it, or their editor is incapable of it in the first place), why would it not be practical when a tool takes care of it for you and everybody uses that tool?

And yet gofmt seems to work.

Why? If the distinction between indentation and alignment can be made and can be made correctly, it means anyone can pick the tabwidth they prefer and things will just look right for everybody, that's strictly superior to either tabs or spaces. That's been advocated for decades, it just doesn't work when you leave it to people, which gofmt doesn't.

I'm quite far from a go fan, but achieving the ideal of "tabs for indentation, spaces for alignment" is definitely praiseworthy, whatever you think of other formatting rules.

I've worked on a (C++) codebase which mixes tabs and spaces for this reason. It works okay - in particular, since my editor is configured for 4-space tabs, while patches are reviewed in GitHub with an 8-space tabs, any mistakes are likely to be caught in review. But it's not that hard to avoid making them in the first place if you remember to use the space bar to line things up.

gofmt works freaking beautifully for this though. Sure, if I tried to do it myself, I'd screw it up. That's why I don't do things that the computer can do better, easier, faster then I can. I just hit save, and my editor routes it through gofmt and refreshes file. It's to the point where I'll hit ctrl-s after moving a brace just to have gofmt reformat, CAUSE IT DOES IT FASTER THEN I COULD.
