When M-x compile and specifying a compilation command, where is this command stored?
I'd like to use whatever it's stored to, in a function to quickly compile, instead of being prompted for the compile command.
(defun my-build () "" (interactive) (compile "variable")) First, you can specify per-buffer compilation commands using the "local variables" section or hooks. See the docstring of compile-command variable. The default is "make -k ". Here is what I have for an example .c file.
// Local Variables: // compile-command: "gcc cpp10.c -o cpp10 -lm " // End: Emacs will now autofill the "Compile command" with the above string whenever you visit the buffer and run compile, and you just need to confirm.
You can invoke "M-x recompile" to reuse the last compilation command and completely avoid the confirmation prompt. The variable compile-command is updated to reflect the last used compilation command. The information does not persist across Emacs sessions.
When I run C-h f compile, it shows a link to the code. Clicking that links opens the file in Emacs. Reading the code, I see, as Swarnendu did, that compile-command is the variable the code uses to save the compile command. Using C-h v compile-command shows useful information about compile-command.
