vimrc

" Cheat Sheet
" ===========
" <A> Alt
" <S> Shift
" <C> Control
" <D> Command (or apple key on Macs)
" <M> Meta (Windows key)
"
" <CR> Carriage Return (Enter)
" <C-O> switch to normal mode for the following alias command
" <left>, <right>, <up>, <down> arrow keys

" GENERAL SETUP
" -------------
set nocompatible
syntax enable
set encoding=utf-8
filetype plugin indent on

call pathogen#infect()

set mouse=a
"source $VIMRUNTIME/mswin.vim
"behave mswin

set shell=/bin/sh

set tabstop=2
set shiftwidth=2
set softtabstop=2
set expandtab
set encoding=utf-8
set enc=utf-8
set fileencodings=utf-8,latin2,latin2
set backspace=indent,eol,start
set number
set smartindent
set linebreak
set ruler
set scrolloff=5

set wrap
set display=lastline " imagine you have a a single non-breaking line that spans several screens. as soon as wrapping is activated, vim will display '@' signs as placeholders for the wrapped lines when you scroll with the mousewheel. by setting this option, the actual content and not the '@' sign will be shown.

set timeoutlen=500              " if you have two commands, ',dv' and ',d' it will take 'timeoutlen' milliseconds to recognize which one you're going for

" UI DESIGN
" =========

" these two cause trouble when i reload my vimrc
" (which i have to do every time i start vim, at the moment, because otherwise
" <D-left> won't jump to the first character of the line) - Rails's 'render',
" e.g., will not be highlighted anymore.
" syntax highlighting on program start is still fine - maybe this is too late a point to
" call these two?

" commenting out these causes the following error:
"Error detected while processing /usr/local/Cellar/macvim/7.3-62/MacVim.app/Contents/Resources/vim/runtime/menu.vim:
"line  450:
" 'E329': No menu '&Tools'
"line 1205:
" 'E334': Menu not found: Tools.Spelling.To\ Next\ error^I]s
" 'E334': Menu not found: Tools.Spelling.To\ Next\ error^I]sError detected while processing /usr/local/Cellar/macvim/7.3-62/MacVim.app/Contents/Resources/vim/runtime/menu.vim:
" but fixed syntax highlighting problems

colorscheme molokai
"set background=dark
"colorscheme solarized

set t_Co=256 " enable 256 colors within vim - grey background, proper syntax highlighting etc.
set gfn=Menlo:h14
"set gfn=Inconsolata:h15
set guioptions-=T "remove toolbar

" start fullscreen
set lines=999
set columns=999
" set colorcolumn=80 " highlight column 80


" LOCALISATION
" ============
set langmenu=en_GB.UTF-8    " sets the language of the menu (gvim)
"language en                 " sets the language of the messages / ui (vim) - throws an error for me: E197: Cannot set language to 'en'


" FILETYPES
" =========
" RABL support
autocmd BufRead,BufNewFile *.rabl setf ruby
autocmd BufRead,BufNewFile *.pde setf javascript
autocmd BufRead,BufNewFile *.hamlbars setf haml
autocmd BufEnter,BufRead,BufNewFile *.hamlc setf haml
autocmd BufEnter,BufRead,BufNewFile *_spec.coffee setf jasmine.coffee " Sets *Spec.js and *SpecHelper.js files to filetype=jasmine.javascript syntax=jasmine
autocmd BufEnter,BufRead,BufNewFile *.mustache setf html

" BACKUPS
" =======

" put all temporary and swap files into a single folder; '//' makes sure swap
" filenames start with the files' full pathname, this prevents duplicate swap
" files for files with the same name in different locations
set backupdir=~/.vim_backups//
set directory=~/.vim_backups//
