  • lowkey, on 10/12/2007, -0/+4Ok a 1 minute time to replace all the symbols is a joke. one last try.

    For the spellcheck toggle, the nnoremap line should read:
    nnoremap <silent> <F7> <ESC>:call <SID>ToggleSpell()<CR>

    And the complete Python function should read like:
    function! s:MyPythonSettings()
    setlocal autoindent
    let python_highlight_all=1
    let python_space_errors=1
    let python_no_tab_space_error=1

    " load pydiction complete file
    set complete+=k/home/lowkey/.vim/pydiction
    set isk+="i.,("

    " Insert comments markers
    map - :s/^/#/<CR>:nohlsearch<CR>
    " Insert wrapping comments around a single line
    map { :s/^(.*)$/"""n1n"""/<CR>:nohlsearch<CR>

    if !exists("g:loaded_pygrep")
    function! PythonGrep(tool)
    set lazyredraw
    " Close any existing cwindows.
    cclose
    let l:grepformat_save = &grepformat
    let l:grepprogram_save = &grepprg
    set grepformat&vim
    set grepformat&vim
    let &grepformat = '%f:%l:%m'
    if a:tool == "pylint"
    let &grepprg = 'pylint --parseable=y --reports=n'
    elseif a:tool == "pychecker"
    let &grepprg = 'pychecker --quiet -q'
    else
    echohl WarningMsg
    echo "PythonGrep Error: Unknown Tool"
    echohl none
    endif
    if &readonly == 0 | update | endif
    silent! grep! %
    let &grepformat = l:grepformat_save
    let &grepprg = l:grepprogram_save
    let l:mod_total = 0
    let l:win_count = 1
    " Determine correct window height
    windo let l:win_count = l:win_count + 1
    if l:win_count <= 2 | let l:win_count = 4 | endif
    windo let l:mod_total = l:mod_total + winheight(0)/l:win_count |
    execute 'resize +'.l:mod_total
    " Open cwindow
    execute 'belowright copen '.l:mod_total
    nnoremap c :cclose
    nnoremap q :cclose
    set nobuflisted
    set nolazyredraw
    redraw!
    endfunction

    if ( !hasmapto('PythonGrep(pylint)') && (maparg('') == '') )
    map <F3> :call <SID>PythonGrep('pylint')<CR>
    map! <F3> :call <SID>PythonGrep('pylint')<CR>
    else
    if ( !has("gui_running") || has("win32") )
    echo "Python Pylint Error: No Key mapped.n".
    "F3 is taken and a replacement was not assigned."
    endif
    endif

    if ( !hasmapto('PythonGrep(pychecker)') && (maparg('') == '') )
    map <F4> :call <SID>PythonGrep('pychecker')<CR>
    map! <F4> :call <SID>PythonGrep('pychecker')<CR>
    else
    if ( !has("gui_running") || has("win32") )
    echo "Python Pychecker Error: No Key mapped.n".
    "F4 is taken and a replacement was not assigned."
    endif
    endif
    let g:loaded_pygrep=1
    endif
    endfunction

    function! s:MyShellSettings()
    set commentstring=# %s
    set formatoptions=croq2lv
    " Insert comments markers
    map - :s/^/#/<CR>:nohlsearch<CR>
    " Syntax file options
    let highlight_function_name = 1
    endfunction

    function! s:MyVimSettings()
    set commentstring=" %s
    setlocal tabstop=4
    setlocal shiftwidth=4
    " Insert comments markers
    map - :s/^/"/<CR>:nohlsearch<CR>
    " Source vimrc and files in .vim/[colors,indentplugin] after saving them
    " (vimtip#879).
    augroup vimrc_vim
    autocmd! bufwritepost ~/.vimrc source ~/.vimrc
    autocmd! bufwritepost ~/.vim/colors/*.vim exec 'source ' . expand("%:p")
    autocmd! bufwritepost ~/.vim/indent/*.vim exec 'source ' . expand("%:p")
    autocmd! bufwritepost ~/.vim/plugin/*.vim exec 'source ' . expand("%:p")
    augroup end
    endfunction

    OK that should do it. As they say no good deed goes unpunished.
  • lowkey, on 10/12/2007, -1/+3incremental search? scrolloff? wildmode?

    Customizations for beginners maybe.

    For a lot more and cooler stuff look at http://www.vim.org/tips/index.php and http://www.vim.org/scripts/index.php.

    For example VimTip# 498 describes how to use the syntax files to enable language specific tab completion liike so:
    augroup vimrc_keyword
    autocmd!
    autocmd FileType * exec( 'setlocal dict+=' . $VIMRUNTIME . '/syntax/'
    . expand('') . '.vim' )
    augroup end

    Or you can toggle spellcheck in Vim7 with:
    if v:version >= 700
    function! ToggleSpell()
    if &spell != 1
    setlocal spell spelllang=en_us
    else
    setlocal spell!
    endif
    endfunction
    nnoremap :call ToggleSpell()
    setlocal spell spelllang=en_us
    endif

    now just press F7 to see all those misspellings highlighted.

    Or trim all blank spaces off the ends of all lines by pressing F12:
    map mz:%s/s*$//g:nohlsearch`z

    Or my favorite, load filetype specific settings automagically as the file loads:
    augroup vimrc_filetype
    autocmd!
    autocmd BufReadPre *.doc set filetype="msword"
    autocmd BufReadPost *.doc silent %!antiword "%"
    autocmd FileType c call s:MyCSettings()
    autocmd FileType perl call s:MyPerlSettings()
    autocmd FileType python call s:MyPythonSettings()
    autocmd FileType sh call s:MyShellSettings()
    autocmd FileType vim call s:MyVimSettings()
    augroup end

    function! s:MyCSettings()
    set cindent
    let c_gnu = 1
    let c_comment_strings = 1
    let c_no_if0 = 1
    let c_space_errors = 1
    let c_syntax_for_h = 1
    endfunction

    function! s:MyMSWordSettings()
    " Must have Antiword (URL: http://www.winfield.demon.nl/)
    " or Catdoc (http://www.45.free.net/~vitus/ice/catdoc/)
    " (vimtip#790)
    " also look into unrtf http://www.gnu.org/software/unrtf/unrtf.html
    set readonly
    set hlsearch!
    endfunction

    function! s:MyPerlSettings()
    set autowrite
    " set errorformat=%f:%l:%m
    set formatoptions=croq
    set keywordprg=man -S 3
    let perl_want_scope_in_variables = 1
    let perl_extended_vars = 1
    "set makeprg=/usr/share/doc/vim/tools/efm_perl.pl -c % $*
    noremap :call Executor()
    endfunction

    function! s:MyPythonSettings()
    setlocal autoindent
    let python_highlight_all=1
    let python_space_errors=1
    let python_no_tab_space_error=1

  • Inaeth, on 10/12/2007, -0/+1@lowkey

    Awesome post, Lowkey! I just submitted the article in a humorous attempt to keep the text editor wars alive (like many people on Digg actually care about what kind of text editor that they use, most of them are happy just to tool around with Kate or KWrite), but you definitely upped the ante. Not only was the info you posted informative, but useful as well. Not to mention the URL's that also were posted!

  • lowkey, on 10/12/2007, -0/+1followup cause of the length limit -----

    if l:win_count
  • lowkey, on 10/12/2007, -0/+1So it wasn't a length limit, it was because digg doesn't allow HTML tags but does not allow greater than and less than symbols. so it broke text.

    if l:win_count
