" background. When set to 'light', Vim will try to use colors that look good on
" a light background.
set background=dark

" Load color scheme
colorscheme solarized

" By default, airline will use unicode symbols if your encoding matches utf-8.
" If you want the powerline symbols set this variable:
let g:airline_powerline_fonts = 1

" Enable/Disable enhanced tabline.

" slow.

set title

" Print the line number in front of each line.
set number

" Show the line number relative to the line with the cursor in front of each
" line. Relative line numbers help you use the count you can precede some
" vertical motion commands (e.g. j k + -) with, without having to calculate it
" yourself.
set relativenumber

" Minimal number of columns to use for the line number. Since one space is
" always between the number and the text, there is one less character for the
" number itself.

" difference between tabs and spaces and for trailing blanks.

set textwidth=80

" This option changes how text is displayed. It doesn't change the text in the
" buffer, see 'textwidth' for that.
" When on, lines longer than the width of the window will wrap and displaying
" continues on the next line. When off lines will not wrap and only part of long
" lines will be displayed. When the cursor is moved to a part that is not shown,
" the screen will scroll horizontally.
set wrap

" Number of characters from the right window border where wrapping starts. When
" typing text beyond this limit, an <EOL> will be inserted and inserting

" of highlighting used can be set with the 'l' occasion in the 'highlight'
" option.

" set with 'matchtime'.
set showmatch

" Tenths of a second to show the matching paren, when 'showmatch' is set.
