.vimrc options to assist with perl coding

Although not perl code, this has sped up my development in perl markedly.

Stole (and altered) this off a friend of mine who found it and altered it somewhere else.

For those who are that way inclined, you can also do similar things with php.

Simple instruction: F1 validates the per... checking for syntax errors etc etc, and brings up the results in a new window. f2 closes the window.

f3 runs the perl script, bringing up the results in a new window. (again) f2 closes the window. Generally, I use this for debugging.

Improvements and suggestions welcomed.

" F2 close current window (commonly used with my F1/F3 functions)
noremap <f2> <Esc>:close<CR><Esc>

" perl -cw buffer, using a temp file, into a new window
function! PerlCW()
    let l:tmpfile1 = tempname()
    let l:tmpfile2 = tempname()

    execute "normal:w!" . l:tmpfile1 . "\<CR>"
    execute "normal:! perl -cw ".l:tmpfile1." \> ".l:tmpfile2." 2\>\&1
+ \<CR>"
    execute "normal:new\<CR>"
    execute "normal:edit " . l:tmpfile2 . "\<CR>"
endfunction

" perl buffer, using a temp file, into a new window
function! PerlOutput()
    let l:tmpfile1 = tempname()
    let l:tmpfile2 = tempname()
    
    execute "normal:w!" . l:tmpfile1 . "\<CR>"
    execute "normal:! perl ".l:tmpfile1." \> ".l:tmpfile2." 2\>\&1 \<C
+R>"
    execute "normal:new\<CR>"
    execute "normal:edit " . l:tmpfile2 . "\<CR>"
endfunction

" Settings for editing perl source (plus bind the above two functions)
function! MyPerlSettings()
    if !did_filetype()
        set filetype=perl
    endif

    set textwidth=78
    set expandtab
    set tabstop=4
    set shiftwidth=4
    set cindent
    set comments=:#
    set formatoptions=croql
    set keywordprg=man\ -S\ 3
    
    noremap <f1> <Esc>:call PerlCW()<CR><Esc>
    noremap <f3> <Esc>:call PerlOutput()<CR><Esc>
   
endfunction

    if has("eval")
           augroup SetEditOpts
            au!
        autocmd FileType perl :call MyPerlSettings()
    augroup END
   endif
