External editor on Cygwin

[keiviv]

Environment details (Put x in the checkbox along with the information)

• Operating System: Windows 10 Enterprise LTSC 1809 + Cygwin latest
• Terminal Emulator: mintty
• Shell: fish
• Program options used: -e
• Issue exists on nnn master

Exact steps to reproduce the issue

This issue applies only to native Windows editors, such as nvim. Cygwin editors (vim, nano, etc) work 100% correctly.
c:/cygwin/home/file.txt -> press e -> editor opens a non-existent /home/file.txt with c:/cygwin missing.
Works correctly if rename file.txt to file.any and select the editor in the opener.

I realize that nnn on Windows is rare, but hopefully this issue is solvable. Such an amazingly perfect file manager, feel like missing a hand without it...

it's because cygwin doesn't report the actual filepath

try a wrapper.sh script something along the lines of :

#!/usr/bin/env sh
myRealEditor "$(cygpath "$@")"

export EDITOR=wrapper.sh

Untested and may not work at all

EDIT: use the solution below provided by @keiviv

Works, thank you so much!
So it seems like a Cygwin issue, not nnn's. Closing, hopefully this will help someone else searching.
You rock, @0xACE !

Forgot to mention that cygpath needs -w option here, won't work without it!

#!/usr/bin/env sh
nvim "$(cygpath -w "$@")"

Was too happy @0xACE generally solved this within minutes in their head, like some Sherlock Holmes 📚.

To use the same config on a non-Cygwin OS, use a uname check. The following is for fish, but you can adapt it for any shell:

# Export EDITOR
if uname -a | grep -iF 'cygwin' >/dev/null
   set -gx EDITOR nvim-cygwin-wrapper
else
   set -gx EDITOR nvim
end
