Vim Shortcuts or plug-ins for the following

Question

I have been using the Sublime editor and is making a switch to vim (Because I have to) . I have heard that Vim is the best editor there is, if you can master all the shortcuts. Given below are some of my needs. Please tell me which shortcut/plug-in I should use to achieve them.

1. Switch-case statement in C : I need like 10 cases. So How can I add them quickly? Is there something like case n:10+ ?
2. Curly Bracket completion : I need an auto closing curly bracket }. Same need with parenthesis.
3. In CSS : Code completion for properties.
4. Code shrink option : In Sublime u could shrink the code present in a block (like a function or loop) by pressing an > like symbol to the left of line number. Is this possible in Vim?
5. Any other shortcut / plug-in that programmer ( C, C++, php, CSS, HTML ) can use to increase his/her productivity.

Any help is appreciated.

   ocase :<CR>break;<Esc>

   See :help repeating.

   Take a look at SnipMate or Ultisnips, though.

2. Curly Bracket completion : I need an auto closing curly bracket }. Same need with parenthesis.

   That "feature" is not that useful but if you didn't already grow tired of it, you can find a good list on the Vim wiki..

3. In CSS : Code completion for properties.

   It's built-in. Try <C-x><C-o> after a couple of characters. If you don't like the default <C-x><C-o>, create your own with:

   inoremap <key> <C-x><C-o>
   

   See :help key-mapping and :help key-notation.

4. Code shrink option : In Sublime u could shrink the code present in a block (like a function or loop) by pressing an > like symbol to the left of line number. Is this possible in Vim?

   That feature is universally called "folding". You can close a fold with zc, open it with zo, toggle it with za and much more. See :help folding.

5. Any other shortcut / plug-in that programmer ( C, C++, php, CSS, HTML ) can use to increase his/her productivity.

   Learn Vim before looking for plugins.

Answer 2

1. With a ctags database correctly configured and up-to-date, if your switch is on an enum, then lh-cpp provides (through mu-template) the CTRL-X_se mapping that will generate your switch-case. If your want to generate it from integers, it will be possible (but a little bit tricky without mappings/commands to encapsulate it)

   :call MuTemplate('c/switch', {'values':reverse(range(1,5)), "name": "foo"})

2. lh-cpp embeds lh-brackets that'll offer a nice brackets support.

3. (SO renumbers 4 to 3 if I write no "3." -> this empty and useless answer)

4. This is called folding in Vim. Usually people are using syntax or indent foldingmethod. I got tired of it and reworked and old plugin for C and C++ -- the plugin still needs many improvements.

5. There are many. In C and C++ YouComplete is a must have. Then I use my plugins to integrates CMake, have a project notion. Other people use other things. There is no definitive answer to this question.
