hotkeys's Issues

Better error handling

Came back to this after unlocking my screen:

Traceback (most recent call last):
  File "/Users/donaldchea/Projects/d/hotkeys/hotkeys.py", line 111, in <module>
    main_loop()
  File "/Users/donaldchea/Projects/d/hotkeys/hotkeys.py", line 100, in main_loop
    context = get_context(active_app)
  File "/Users/donaldchea/Projects/d/hotkeys/hotkeys.py", line 55, in get_context
    out = subprocess.run(cmd, capture_output=True, universal_newlines=True, check=True).stdout
  File "/Users/donaldchea/.asdf/installs/python/3.9.1/lib/python3.9/subprocess.py", line 524, in run
    raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError: Command '['ps', '-t', 'ttys007', '-opid=,stat=,command=']' returned non-zero exit status 1.

Sometimes commands fail, who knew?

In any case, this doesn't give us any information other than the exit code.

• Is there anything in stderr we can capture in this case?
• We can't really display errors to on the screen unless we crash/pause
  • we can't right now because screen is constantly cleared
  • if we can find a nice tui to use, we could potentially display the last error
• Maybe we can just log to a file?

Add GitHub Action

What python tooling is available?

Minimum would be:

• flake8 to enforce style

Find a better way of determining the context of an iTerm2 window

When iTerm2 is the current app, we use ps to figure out the foreground process.

Is there a good way to figure this out?
If it's a list of pipeline processes, it's possible we won't know which process to use.

SIngle process

It returns a process with status S+ when the app is "sleeping" or R+ if it's running (not sure the difference atm).

S+ or R+?

In some cases it can have S+ and R+. We are preferring S+ as the "foreground" process here.

Multiple processes (S+, R+?)

In other cases, there may be multiple S+ processes as is the case here.

Find method to handle cleanup on exit

When the script is started, the cursor is hidden.
Is there a good way to ensure the terminal is restored to the proper state when the script exits?

We handle ctrl+c.

But the script can raise or receive SIGTERM, etc.
