Seems like you are just starting out with vim\|emacs. Both require some quality time to be spent with them to have them bent per your desires (almost). Please see :help on :buffers, :map, :make & :cwindow (which I found via tips search section of Vim home), among other commands. I don't run a program through vim, only to check if perl will compile it (`map <F5> :setlocal makeprg=perl\ -c\ %\\|make<CR>`). I do have an occasionally exercised key binding to run the program: `map <F6> :setlocal makeprg=perl\ %\\|make<CR>`. Yes, edit-Ctrl-Z-run-fg cycle is indeed tedious for more than thrice. I much prefer to use two xterm windows: one for the editor; other to run and redirect output as I like. Along with command history as pointed out earlier, there is also xterm buffer space to temporarily hold some adjustable number of lines of text. I don't like a split window (in any of vim or emacs) which causes small viewport, thus much scrolling. On a big monitor (or two side by side), both windows will be side by side. Else, I just use my window manager's key binding to flip between the windows. I must admit that if I were to be working on console (about 25x80 resolution) with access to only one tty, I would be extremely motivated to run a program within vim and to find a way to save output in a file which would linger around and be inserted in buffer list.

When working with limited nix consoles, I find it very convenient to use a virtual window manager* like screen. Especially when dealing with multiple remote logins, it can help to keep the working environment clear. I often use one xterm for emacs and another ~~xterm~~ PuTTY terminal that runs screen with multiple logins on the same or different hosts.	[reply]

Dunno about vim, but in emacs it's fairly simple: I've got mode-compile on and then it's just a question of typing C-c c ENTER to run the current perl script, with output to a split buffer and clickable error messages (or press C-x ` to go to the next error).

Haven't used mode-compile myself before (but will take a look!) I tend to just use `M-x compile` in my Emacs (normally an `emacs -nw` on an ssh session to a server) combined with an `M-x shell` buffer where I run little test iterations from the shell. Something like this in .emacs: `(add-hook 'perl-mode-hook (lambda () (unless (or (file-exists-p "makefile") (file-exists-p "Makefile")) (set (make-local-variable 'compile-command) (concat "perl -c " (file-name-completion buffer-file-name))) +)))` [download] can bind the default `M-x compile` to run the perl interpreter on your code and if there are errors hitting Enter on the error message will take you to the offending line in your code buffer. Having the shell running in an emacs buffer is handy because the whole buffer (or a region of it) can be saved for documentary purposes and you can go back to pick up a command from previously, edit it and re-run it. Since many of my such trials are faking a CGI run (e.g. `perl ./blah.pl param1=fred param2=yaada param3=DoIt`), it's fairlly easy to tailor and then modify the command from one trial to another.

I usually edit with gvim, and test in an xterm alongside. I've used screen before, that also works well. It's all a matter of personal preference, of course. There's no wrong answer. Insert a "now if only emacs had a good editor, it'd be the answer" joke here :) Emacs does actually have a good terminal mode, so if you can stand using it to edit, it is a good choice. Mike	[reply]

one window for editor, another window for `./foo.pl` with history feature (so you can up arrow through previous commands) works the way I like it	[reply] [d/l]

> one window what exactly to you mean with this window: - vim window? - terminal window (terminal.app, xterm,..)? - GNU screen window? and further: - how do you combine save of the script and switch to the window? - how do you setup that keybinding?	[reply]

Super Search is helpful; See e.g. Editing features for advanced users and .vimrc for perl programmers	[reply]

You may take advantage of Vim's Quickfix List window. Place this in your `.vimrc`: `function! RunCmd(cmd) let fn = expand("%:p") let ft = &l:filetype botright copen setlocal modifiable %d _ silent execute "read !".a:cmd." ".fn 1d _ normal! 0 if ft != "" execute "setf ".ft else setlocal filetype= endif setlocal nomodifiable nomodified wincmd p endfunction command! -nargs=1 Run call RunCmd(<q-args>) command! RunPerl call RunCmd("/usr/bin/perl")` [download] Then, while editing your script in the current Vim buffer, do: `:RunPerl` [download] or `:Run perl` [download] You should be able to also map these commands to shortcut keys. YMMV -- perhaps something like: `nnoremap <silent><F5> :<C-u>up\|RunPerl<CR> inoremap <silent><F5> <C-o>:up\|RunPerl<CR> vnoremap <silent><F5> <Esc>:up\|RunPerl<CR>gv` [download]	[reply] [d/l] [select]
