Auto Indent (the = key) of C switch block

Question

For the following switch block:

If I select the switch block and apply the auto format command, the = key, I get the following:

The block is formatted correctly in the first image, but it gets messed up by auto format. It works fine on if blocks, but really messes up the case blocks. What controls the auto-format? Is there any way I can adjust the configuration to apply camel style brackets?

Answer 1

The configuration of C indenting in Vim is controlled by the cinoptions option. That particular aspect of indenting is controlled by the l (lower-case L) flag. When set to any value other than 1, it will "align with a case label instead of the statement after it in the same line."

So, you can get the indenting style you want by putting this in your ~/.vimrc on Unix or ~/_vimrc on Windows:

set cinoptions+=l1

See

:help cino-l
:help cinoptions-values
:help 'cinoption'
:help C-indenting
:help 30.2

Those topics are ordered roughly from particular to general aspects of C indenting.

You can find out more about auto-format here:

:help auto-format

although I don't think that's what you mean by "auto format".

Also, those { and } are called braces. Brackets are the more squarish [ and ].
