You can set pretty much any editor to display tabs as whatever amount of indent you want. Harder to do that with spaces.
Also spaces = tons of unnecessary button pushing.
In 2016 I think the best approach is pick a formatter (gofmt-alikes 'standardjs' etc) run it on save and not think about it anymore.
Vouching for this, since it's a plot point in the latest Silicon Valley episode and not a random request of preference.
Imagine doing it 1000 times. That's 3000-4000 space presses or 1000 tabs. RSI is not fun.
The IDE/editor takes care of that. But I still like tabs.
I have my tabs set to 3-4 spaces - nothing is more annoying than opening in a program with a long default tab.. spaces preserve the format better across systems IMO
Tabs
Spaces.The right amount is inserted by autoindent or by setting tab width to the desired value and hitting tab then.
Tabs for indentation, spaces after that for alignment (aka "smart tabs").
