What is the most efficient way to run programs in Emacs after compiling Mx

Question

I started using Mx compilation to compile programs in say, C.

What is the most efficient way to run an executable, for example. a.out. At the moment I am using M -! ./ a.out. Basically, what is the best code compilation procedure?

Almost all textbooks mention how compilation is done, but I have not seen the one who solved this problem?

Thanks Samuel

Answer 1

I just simply add a run command at the end of the assembly:

Mx compile RET gmake && ./a.out 

&& will tell the shell to only a.out when the compilation is successful.

Although I often run the program from an existing shell buffer ( Mx shell ) or from one of the many shells that I manage with a package very similar to screen .

I use the smart-compile + extension, it allows you to specify fairly convenient rules depending on the name of the file / buffer you are editing. For example, in my .emacs, I specify the following rule when running smart-compile in the project’s eilers file:

 (add-to-list 'smart-compile-alist '("euler.*\\.[Cc]+[Pp]*$" . "g++ -O2 -Wall -pedantic -Werror -Wreturn-type %f -lm -lgmpxx -lgmp -o ../bin/%n && time ../bin/%n") ) 

First you specify the file name template for the rule, then the path where it should be executed, and then the compilation command. In the above case, I add && time ../ bin /% n to run the program immediately after it has successfully compiled.

My first choice is for interactive development; code, upload files to REPL, resolve errors (with Cx `, as with Mx compilation), and then play the code in REPL.

If this is not an option, I use eshell as a generic REPL. Compile, switch to eshell, run, verify, retry.

Add the rule to your make file to compile and run your program, so Mx compile will compile and run, check, valgrind-test ... all
