Post-run commands about vim-xcode HOT 8 OPEN

I've been thinking about this lately as well. Based on this answer (which seems to be accurate), the logs are currently in ~/Library/Logs/CoreSimulator/<simulator-hash>/system.log

Based on the run script we already have the UDID for the simulator. So we could probably do something smart, especially with tmux, to spawn a new pane/window running a tail -f to this log.

Maybe the Xrun command should also print out the path to ~/Library/Logs/CoreSimulator/<simulator-hash>/system.log so we can tail it into any terminal pane of our choice

@keith and I have been talking about using hooks for things like this and possibly LLDB access. I wonder if something like this would work:

let g:xcode_post_run_command = "tail ~/Library/Logs/CoreSimulator/{sim-hash}/system.log"

That could be the default, but you could override it with whatever you want. We'd then just send that command to the already-defined runner command.

For now we could simply pass the sim hash, but it's possible that we could get more intricate with multiple tokens ({pid}, {sim-hash}, {bundle-id}, ???). This would also mean moving the run commands to be internal instead of being sent to the runner command (because otherwise we'd have no way to know when the run command completed successfully). I'm OK with that.

I think if we were to do something like this we'd actually need to make it an array of commands, or an array of functions. Because now we have at least 2 use cases for this that you would ideally use simultaneously

seems reasonable

Updating the name to track what we actually want out of this.

I'm a little worried that #69 actually complicates this a bit. Since we're now building & running, it's going to be hard to know when the run command has completed, and so it'll be hard to get the pid/simulator uuid/etc.

I'd like to try expanding on this as outlined in here, but for now, I've opened a PR (#76) to tail the logs by default after running.

from vim-xcode.

So now with os log you can use a command with simctl in order to get live logs from the simulator. I think this is something we should just advice people to do in a separate pane, as it can be left open between runs
