運行選擇並替換

Question

如果我可以將選定的Emacs文本區域作爲c或C++程序的輸入運行，那將會很好。程序的輸出可以覆蓋選定的文本。有這樣的功能嗎？

Answer 1

shell-command-on-region is an interactive compiled Lisp function in 
`simple.el'. 

It is bound to <s-kp-bar>, s-|, M-|, <menu-bar> <tools> 
<shell-on-region>. 

(shell-command-on-region START END COMMAND &optional OUTPUT-BUFFER 
REPLACE ERROR-BUFFER DISPLAY-ERROR-BUFFER) 

Execute string COMMAND in inferior shell with region as input. 
Normally display output (if any) in temp buffer `*Shell Command Output*'; 
Prefix arg means replace the region with it. Return the exit code of 
COMMAND.
