Thank you!

@jarun Thank you for merging!

It would be great if you can setup an automated compilation in Travis for FreeBSD. Please refer to .travis.yml.

Unfortunately, Travis CI currently doesn't support FreeBSD - travis-ci/travis-ci#6671

BTW, I've just submitted nnn FreeBSD port, https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=224600
It should hit the ports tree in a day or two and then it'll be available for installation as pkg install nnn.

I didn't know. It's a pity!

Awesome, thank you! Please leave a note when it's in so I can add to the readme. Or maybe just raise a PR following the alphabetical order and instruction.

@jarun I'll raise a PR when it's ready. Thanks for the great software!

[jarun]

Would you be kind enough to submit imgp to FreeBSD?

[dmgk]

@jarun I'm not a Python developer, but you ask someone in #freebsd or #freebsd-ports on freenode to do a FreeBSD port.

Sure thing! Thanks!
