#tabstop

While pushing changes to Jenkins for review I noticed that I was indenting ruby code too much.. 4 spaces instead of 2 for a tab. This puzzled me as I had a .vimrc which seemed to be correct:

autocmd FileType ruby setlocal shiftwidth=2 tabstop=2 softtabstop=2

Examining the file with the vim command

:set list

showed that there were

^I

characters inserted for every place where I had inserted a tab. Simply trying to reformat using

gg=G

changed nothing. I later realized that I need to expand the tabstops to spaces

autocmd FileType ruby setlocal shiftwidth=2 tabstop=2 softtabstop=2 expandtab

Then within vim

:retab
