2. define functions

Vim:

Function Fun () // if the scope limit is not used, the first letter must be capitalized.

Endfunction

Command Line call: command! -Nargs = 1 Gdb :! Command "<args>"

Emacs:

(Defun fun ()

"Message"

(Interactive)

.....

)

3. Execute Functions

Vim:

Call function ()

Emacs:

(Fun)

4. conditional statements

Vim:

If c

Elseif B

Else e

Endif

While

Endwhile

Emacs:

(If

'Thenfun

'Elsefun)

(While (equal a B)

Body...

(Counter ))

(Cond

(First ...)

(Second ...))

5. Automatic Execution

Vim:

Autocmd BuffRead *. cpp: call fun

Emacs:

(Add-hook 'C ++-mode-hook' (lambda ()

(Interactive)

.....))

6. Reference other files

Vim:

Source name. vim

. Name. vim

Emacs:

(Require 'name); you must add (provied 'name) at the end of the file)

(Load "name. el ")

7. Bind a shortcut key

Vim:

Nmap <silent> <F8>: call fun () <CR>

Imap <F9>: call fun () <CR>

Vmap <F10>: call fun () <CR>

Emacs:

(Global-set-key [f8] 'fun)

(Define-key c ++-mode-map (kdb "C-\") 'fun)
