Hi, I'm using tview to build a shared note-taking tool: https://github.com/JesseAldridge/dentist
I'm wondering if it's possible to get tview to work well with Vim.
Below is a test script. Vim gets launched successfully but the input seems to be conflicting with tview somehow and it doesn't work well.

I'm new to Go and tview so maybe I'm doing something wrong.

package main

import (
	"os"
	"os/exec"

	"github.com/gdamore/tcell"
	"github.com/rivo/tview"
)

func write_and_open(note_name string) {
	cmd := exec.Command("vim", note_name)
	cmd.Stdin = os.Stdin
	cmd.Stdout = os.Stdout
	cmd.Run()
}

func main() {
	app := tview.NewApplication()

	app.SetInputCapture(func(event *tcell.EventKey) *tcell.EventKey {
		k := event.Key()
		if k == tcell.KeyEnter {
			write_and_open("test name")
		}
		return event
	})

	box := tview.NewBox().SetBorder(true).SetTitle("Hello, world!")
	if err := app.SetRoot(input_field, true).Run(); err != nil {
		panic(err)
	}
}

Actually, looks like I just need to wrap the vim call with Stop and Run:

		if k == tcell.KeyEnter {
			app.Stop()
			write_and_open("test name")
			app.Run()
		}

I know you closed this already but while Stop() and Run() should probably work, there is a function dedicated to these kind of situations: Suspend().

I thought this may be useful to you.

@rivo commented on GitHub (Sep 10, 2018): I know you closed this already but while `Stop()` and `Run()` should probably work, there is a function dedicated to these kind of situations: [`Suspend()`](https://godoc.org/github.com/rivo/tview#Application.Suspend). I thought this may be useful to you.

Actually I'm still seeing some odd behavior. Everything works well when I use vim as the editor. But if I use subl instead, after I finish editing the file and come back to the terminal my next keystroke seems to get dropped.

In the demo below I run the script, hit return to open sublime, close the text file, select the terminal, press return again (nothing happens), press return again (sublime opens again). I get similar behavior if I use subl -w instead of subl.

subl is configured like so: https://www.sublimetext.com/docs/3/osx_command_line.html

Any idea what the issue could be?

package main

import (
	"os"
	"os/exec"

	"github.com/gdamore/tcell"
	"github.com/rivo/tview"
)

func write_and_open(note_name string) {
	cmd := exec.Command("subl", note_name)
	cmd.Stdin = os.Stdin
	cmd.Stdout = os.Stdout
	cmd.Run()
}

func main() {
	app := tview.NewApplication()

	app.SetInputCapture(func(event *tcell.EventKey) *tcell.EventKey {
		k := event.Key()
		if k == tcell.KeyEnter {
			app.Suspend(func() { write_and_open("test name") })
		}
		return event
	})

	box := tview.NewBox().SetBorder(true).SetTitle("Hello, world!")
	if err := app.SetRoot(box, true).Run(); err != nil {
		panic(err)
	}
}

I should probably open a separate issue for this: https://github.com/rivo/tview/issues/165
