" What this indent plugin currently does:
|
|
" - If no other rule matches copy indent from previous non-empty,
|
|
" non-commented line
|
|
" - On '}' align the same as the line containing the matching '{'
|
|
" - If previous line ends with ':' increase indentation
|
|
" - If the current line ends with ':' indent at the same level as the
|
|
" enclosing '{'/'}' block
|
|
" Stuff that would be nice to add:
|
|
" - Continue comments on next line
|
|
" - If there is an opening+unclosed parenthesis on previous line indent to that
|
