( #3333=superdoc: print w/replies, xml ) Need Help??
I started to write this .vimrc file because I wanted my programs to use 4-space (actual spaces!) identation.

That was a simple need, but, after a quick research, I found many features that made Perl programming more enjoyable in Vim.

Without more delay, here's my .vimrc file:

" use visual bell instead of beeping set vb " incremental search set incsearch " syntax highlighting set bg=light syntax on " autoindent autocmd FileType perl set autoindent|set smartindent " 4 space tabs autocmd FileType perl set tabstop=4|set shiftwidth=4|set expandtab|set + softtabstop=4 " show matching brackets autocmd FileType perl set showmatch " show line numbers autocmd FileType perl set number " check perl code with :make autocmd FileType perl set makeprg=perl\ -c\ %\ $* autocmd FileType perl set errorformat=%f:%l:%m autocmd FileType perl set autowrite " dont use Q for Ex mode map Q :q " make tab in v mode ident code vmap <tab> >gv vmap <s-tab> <gv " make tab in normal mode ident code nmap <tab> I<tab><esc> nmap <s-tab> ^i<bs><esc> " paste mode - this will avoid unexpected effects when you " cut or copy some text from one window and paste it in Vim. set pastetoggle=<F11> " comment/uncomment blocks of code (in vmode) vmap _c :s/^/#/gi<Enter> vmap _C :s/^#//gi<Enter> " my perl includes pod let perl_include_pod = 1 " syntax color complex things like @{${"foo"}} let perl_extended_vars = 1 " Tidy selected lines (or entire file) with _t: nnoremap <silent> _t :%!perltidy -q<Enter> vnoremap <silent> _t :!perltidy -q<Enter> " Deparse obfuscated code nnoremap <silent> _d :.!perl -MO=Deparse 2>/dev/null<cr> vnoremap <silent> _d :!perl -MO=Deparse 2>/dev/null<cr>

Most of the features are self-evident when you open your next perl script. Other features deserve some comments:

  • Use ":make" to check your code: it will call "perl -c" to verify your code and, if there are any erros, the cursor will be positioned in the offending line.
  • Get rid of the Ex mode: I often entered in Ex mode when I wanted to type ":q"...
  • Indent code with tabs: Use "v" to select a region, or indent line by line in normal mode. (Use shift-tab to unindent.)
  • Press F11 to toggle the "paste mode", disabling autoindent so that any text you paste won't loose its original layout.
  • UPDATE: added some hints from the comments.

I hope you'll find those tricks useful!

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
