I installed Nedit on my iMac this weekend. I used it several times and it worked fine. For some reason last night it quit working. When I type Nedit in the terminal window I just get the message
NEdit: Can't open display
.
Using Homebrew again, I reinstalled Nedit using
brew reinstall nedit
Nedit still refuses to work. I am totally confused since it worked fine for a day and a half. Any clue why it stopped working? Was the fact that it worked the most confusing issue or the fact that it stopped. Its version 5.7 of Nedit and claims that its for High Sierra.

Looks from your comment that your display variable is not set. Ensure you have an X-Server running (I. E. XQuartz) and then set your display environment variable first with:
Launching applications from within the XQuartz terminal will have the
$DISPLAY
env var set automatically. You can make this change persist by adding that line to your~/.profile
or~/.bash_profile
file:Note that in my setup, XQuartz automatically sets
$DISPLAY
for me without my needing to do this, so you may want to re-install XQuartz.(Or ask a follow-up question about why that behavior isn't working)
