Can't kill a python process in sublime text 2

Question

I've searched in a lot of places but I can't seem to get the keywords correct. I have a stalling process in Python in Sublime that causes the beachball of death on a Mac. I can't access the Tools > Cancel Build button and Control + C doesn't work. How do I kill this process?

Answer 1

This answer is specific to python and windows. I am not sure if there is a mac equivalent.

A running python script can be terminated from the task manager. Use Ctrl+Shift+esc to open the Task Manager. Go to the processes tab and kill python.exe by simply pessing del. This would only terminate the script and leave sublime untouched.

Answer 2

I have not found a way to kill a process in Sublime without killing all of Sublime. But I did find a way to make killing and reopening Sublime much less painful. Here is my way.

1. Command-option-escape: This brings up the force-quit window.
2. The force-quit window will ask you if you really want to quit Sublime twice. Just hit enter twice.
3. A crash reporter window will open. I hated this window, because it floats on top of everything so you can't ignore it, and closing it made me do extra keystrokes, so I disabled it.
4. Reopen sublime. When Sublime re-opens, it opens all of the files you had open before it crashed, taking you back to where you were.

Many people think reopening Sublime is pain in the butt because they have to navigate to the Applications Directory with their mouse, a process which takes about 10 - 30 seconds. I used to find this annoying, so I set it up so that I could reopen sublime with five keystrokes, and it takes me about three seconds.

First, I installed Alfred. In this case, you only need the free version of Alfred.

With Alfred installed, do the following:

1. option-spacebar brings up the Alfred search bar. Alfred is a lot like Google Search for your computer.
2. Type the letters "su." Below the Alfred search bar, a bunch of options appear, and the first option is Sublime Text 2. Alfred automatically highlights the first thing on it's list of search results, so that when you hit enter, it will launch the highlighted application.
3. Hit enter. Alfred opens Sublime. Voila: Sublime is back to how it was before you ran the script.

So, in total, once I start a process that freezes Sublime, I do the following 10 keystrokes:

Cmd-option-escape enter enter option-spacebar s u enter

This procedure does leave the Force Quit Applications window hanging around, because I have not found a quick way to get rid of it without adding ten extra keystrokes to my system. If it really bugs me, I click on the window and do cmd-w, which closes the window.

The other annoying thing is that it takes a couple of seconds for Sublime to relaunch, so usually I don't bother to run things from within Sublime. Instead, I go over to the terminal and run things there, so that I can Ctrl-C the script I'm testing without affecting Sublime.

Additionally, there is a keyboard shortcut for the Tools > Cancel Build option. I have never used it, but using it and fixing problems with it is discussed in this forum post.

I found an interesting way to solve this.

My build system on sublime-text2 call my Makefile which has 2 options and uses the ONESHELL directive:

.ONESHELL:
run: myprogram
    ./myprogram &
    echo $$! > "pid.tmp"

Note that after it starts my program its pid is saved on a file. And i have a second option:

stop:
    kill -9 `cat pid.tmp`
    rm pid.tmp

This option kills the process started by the run command.

Then i configured my build system (Tools -> Build System -> New Build System...) so i could access both options:

{
    "cmd": ["make"],
    "variants":
    [
            {
                    "name": "Run",
                    "cmd": ["make", "run"]
            },
            {
                    "name": "Stop",
                    "cmd": ["make", "stop"]
            }
    ]

}

But i want to call both options from key bindings on sublime so i edited the file "Preferences -> Key Bindings - User" to look like this:

[
{ "keys": ["ctrl+r"], "command": "build", "args": {"variant": "Run"} },
{ "keys": ["alt+r"], "command": "build", "args": {"variant": "Stop"} }
]

Now if i press ctrl+r my program starts (and enters an infinity loop) and when i press alt+r my program stops which is almost what i wanted.

The only problem left is that when i run alt+r i loose the output produced by ctrl+r.

Edit: Other way i found was to start my program on a new xterm process on the Makefile:

run:
    xterm ./myprogram

I can close it with ctrl+c and it wont stop sublime from working.
