I think this is becoming a FAQ... i've seen this asked several times
here now.
I had the same problem. Here's a simple elisp to solve it:
(defun run-current-file ()
"Execute or compile the current file.
For example, if the current buffer is the file x.pl,
then it'll call “perl x.pl” in a shell.
The file can be php, perl, python, bash, java.
File suffix is used to determine what program to run."
(interactive)
(let (ext-map file-name file-ext prog-name cmd-str)
; get the file name
; get the program name
; run it
(setq ext-map
'(
("php" . "php")
("pl" . "perl")
("py" . "python")
("sh" . "bash")
("java" . "javac")
)
)
(setq file-name (buffer-file-name))
(setq file-ext (file-name-extension file-name))
(setq prog-name (cdr (assoc file-ext ext-map)))
(setq cmd-str (concat prog-name " " file-name))
(shell-command cmd-str)))
(global-set-key (kbd "
") 'run-current-file)
