Is focused a custom layout?

[cwpage]

Is focused a custom layout?

It is, yes.

[ianyh]

I did make some changes to custom layouts. Would you be able to share that one?

[cwpage]

Sure, here it is:

function layout() {
  return {
    name: "Focused",
    initialState: {
      mainPaneRatio: 1
    },
    commands: {
      command1: {
        description: "Shrink main pane",
        updateState: (state) => {
          return { ...state, mainPaneRatio: Math.max(0.1, state.mainPaneRatio - 0.05) }
        }
      },
      command2: {
        description: "Expand main pane",
        updateState: (state) => {
          const mpr = state.mainPaneRatio + .05
          return { ...state, mainPaneRatio: Math.min(2, mpr) }
        }
      }
    },
    getFrameAssignments: (windows, screenFrame, state) => {
      return windows.reduce((frames, window) => {
        const frame = {
          x: Math.round(screenFrame.width / 2 - (screenFrame.width * .25 * state.mainPaneRatio)),
          y: screenFrame.y,
          width: Math.round(screenFrame.width * .5 * state.mainPaneRatio),
          height: screenFrame.height
        }
        return {...frames, [window.id]: frame}
      }, {})
    }
  }
}

Okay, there's nothing in that code that seems problematic, and I tested it out and couldn't get anything to slow down as a result.

[ianyh]

Okay, I think I actually see where it is. I changed manageable applications to include a broader swathe, and it's probably catching one you're running that bogs down. You can test this by running the debug command with 0.22 diffed with 0.23

/Applications/Amethyst.app/Contents/MacOS/Amethyst debug apps

which will give you the list of apps Amethyst was ignoring previously, then you can quit anything you are intentionally running to see if it resolves. If you let me know which apps bog down, I can go from there in trying to isolate them somehow.

[cwpage]

Thanks for taking a look and sorry for my delay.

I tried closing all apps that I'm intentionally running besides the terminal and am still observing the non-responsiveness after launching Amethyst.

Here are the app titles from the output of

Thank you!

@cwpage could you give this build a try? #1774 (comment)

[cwpage]

I closed all applications I was intentionally running and still observe the issue when using that build. It's possible the duration of the issue is slightly reduced.

Here's the output of ~ /Applications/Amethyst.app/Contents/MacOS/Amethyst debug apps

After the period of sluggishness, I ran this again and got the same output with one minor difference:

Could be meaningless but just thought I'd point it out.
