Vim: Smart indent when entering insert mode on blank line?

阅读更多关于 Vim: Smart indent when entering insert mode on blank line?

问题 When I open a new line (via 'o') my cursor jumps to a correctly indented position on the next line. On the other hand, entering insert mode while my cursor is on a blank line doesn't move my cursor to the correctly indented location.

问题 I'm working with XCode 3.2 (on "Snow Leopard") which (still) has this nice "Text Macro" auto-completion feature (eg. if you type if it will expand to if (<#condition#>) { <#statements#> } ). These macros are also available via "Edit->Insert Text Macro". Unfortunately, the default templates don't match my beloved indentation and whitespace style so I'd like to modify them. According to this slightly outdated StackOverflow thread the corresponding definitions should be located at /Developer

Here is what I have put in my .emacs: ; Warn in C for while();, if(x=0), ... (global-cwarn-mode 1) ; no electric mode in c (c-toggle-electric-state -1) ;
