📓 spaces to tabs conversion.md by @flancian ☆

To go from spaces to tabs in Python code:
- for i in *py; do unexpand -t 4 $i | sponge $i; done
  - [[sponge]] is in [[moreutils]]
To go from tabs to spaces in Python code:
- for i in *py; do expand -t 4 $i | sponge $i; done
[[pep8]] is against tabs in Python code. We are currently experimenting with using tabs in [[agora server]] regardless.
- In .vimrc you might need to add:
  - ```
  " work around python filetype's insistence that tabs are 8 spaces wide
  let g:python_recommended_style = 0
  filetype plugin indent on
  syntax on
  set tabstop=4
```
- Update: I’m reverting this experiment, I think it would impose too large of a burden on new contributors at this point, as both vim and python seem to assume you want to follow [[pep8]]. The [[google style guide]] also recommends four spaces even though it overrides some other aspects of [[pep8]], so this is pretty widely the standard.
