Is there a way I can compile then run my compiled application, if its already running then exit recompile and run.
So current work flow is compile switch to terminal run binary, switch back make changes compile return to terminal Ctrl + C to kill then run again, be nice if I could do all this from inside emacs.
I guess a bash script could be an option but curious if others have this work flow and how it works ?
Currently in a golang workflow but even better if there is a generic solution.
I did wonder if that’s perhaps the solution, although not sure how you would get the pid in a make file to kill the running instance, make files are not something I have played with much, I will see if others have any suggestions.
There’s only one running
*compilation*buffer allowed at a time, so if you useM-x compile(which I’ve had bound toC-x C-efor like 20 years), that should roughly ensure it.In the past, I also had a bit of elisp to – IIRC – create and rename multiple compilation buffers to be able to run multiple things at once (multiple servers in a control plane).
Okay so what I think your saying is if i do something like this as the compilation command
Then when I run compilation again it will kill the buffer and running process and all will be good ?
yes, should do. It’ll prompt you if you want to kill the existing live compilation to start the new one. If it’s already dead, it’ll just launch the new compilation.
One trick, as well, is if you rename the existing
*compilation*buffer, it will live on its own lifecycle, so you rename it to*server*or whatever, and still do compilation cycles (eg. justgo build main.go) while the existingmainfrom the previous run is still live.Awesome I will give that a try :)
In which case I wonder why you are not running go run anyway?
Probably because I was just getting into golang and following a tutorial which did not mention using go run, but I will now thanks :)
