So I was browsing repl.it and saw that someone made it possible to run firefox in the repl window. There was a file called Makefile and it had this code in it. I’m wondering what it means and where they are getting Firefox from.
.PHONY: run run: install-pkg python firefox python3 launch.py
Then there is a python file called launch.py
def delete(): time.sleep(10) os.remove("nohup.out") print ("Deleted nohup.out.") thread = threading.Thread(target=delete) thread.start() os.system("firefox")
I’m genuinely curious where firefox is coming from and if I can substitute for another app like discord. Aswell as what is makefile Here is a link to the repl where you can hten view the code. https://replit.com/@Jackerin0/Firefox-fixed-originally-made-by-polygott?v=1
Makefile is a utility for writing and executing series of command-line instructions for things like compiling code, testing code, formatting code, running code, downloading/uploading data, cleaning your directory etc … Basically, it helps automate your dev workflows into simple commands (
Here’s what it does in this case:
.PHONY: run # explicitly declare the a routine "run" exists, which can be called with `make run` run: # run routine install-pkg python firefox # first, install python and firefox. This will make both firefox and python available as executable binaries that can be launched from the command line python3 launch.py # this runs the python script
So when you type
make run in terminal, it will run the
Then in the python file:
def delete(): time.sleep(10) # sleep for 10 seconds os.remove("nohup.out") # remove the file named nohup.out print ("Deleted nohup.out.") thread = threading.Thread(target=delete) # create a thread to run the delete function thread.start() # start the thread os.system("firefox") # run the executable for firefox (you can replace this with any command from the command line)
nohup file is created when running a background task. Not sure why it’s being created in this context (maybe because of something specific to
repl), or why you need to delete it.
