| " Vim indent file | |
| " Language: llvm | |
| " Maintainer: The LLVM team, http://llvm.org/ | |
| " 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 | |
