Linux uses 8 spaces. Excerpt from the official style guide:
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.
Rationale: The whole idea behind indentation is to clearly define where a block of control starts and ends. Especially when you’ve been looking at your screen for 20 straight hours, you’ll find it a lot easier to see how the indentation works if you have large indentations.
Now, some people will claim that having 8-character indentations makes the code move too far to the right, and makes it hard to read on a 80-character terminal screen. The answer to that is that if you need more than 3 levels of indentation, you’re screwed anyway, and should fix your program.
In short, 8-char indents make things easier to read, and have the added benefit of warning you when you’re nesting your functions too deep. Heed that warning.
The reasoning seems sound, but I still prefer 4 personally.
Maybe it’s still using the borked config because all sessions were not exited? Try exiting it and then make sure no tmux process is still running, by for example running
ps -aux | grep tmux
.Otherwise there must be some tmux config still lying around in your $HOME.
Edit: I don’t know anything about Macs so I’m just assuming it works similar to linux.
Does fzf search hidden folders? You could also try with this, to make extra sure:
find $HOME -name "*tmux*"
.
