Error Message

And when i use keyboard shortcut ctrl + g, Claude Code fails to open the prompt text or plan in the configured text editor with the following error message: 👉 As we can see from the error text, it appears to cut-off the full absolute configured path string now when it encounters an escaped space within the application name of the JSON settings.json EDITOR environment variable path string value, and hence is the likely root cause.

Root Cause

"env": {
  "EDITOR": "/Applications/Sublime\\ Text.app/Contents/SharedSupport/bin/subl --wait",
},

Bug Description No longer able to open custom configured local text editor with space in application name (e.g. Sublime Text) on MacOS.

My current Claude Code settings.json is setup with the following environment variable(s):

"env": {
  "EDITOR": "/Applications/Sublime\\ Text.app/Contents/SharedSupport/bin/subl --wait",
},

And when i use keyboard shortcut ctrl + g, Claude Code fails to open the prompt text or plan in the configured text editor with the following error message:

Couldn't open Sublime\ — ENOENT: no such file or directory, posix_spawn '/Applications/Sublime\'

👉 As we can see from the error text, it appears to cut-off the full absolute configured path string now when it encounters an escaped space within the application name of the JSON settings.json EDITOR environment variable path string value, and hence is the likely root cause.

However, I am able to run the raw bash command in a new vanilla terminal tab like so:

/Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl --wait

It is IMPORTANT to note that this was working for a long while until recent releases. So this is a RECENT regression.
