Ssh – emacs syntax highlighting fails on the SSH client

emacssshsyntax highlightingterminal

I need to connect to a remote server by SSH to edit some documents. When I work at home, I SSH to the remote server using SSH Secure Shell and open emacs, but it doesn't fully highlight documents as I want:

Is there any way to fix it so that syntax highlighting works like when I ssh through Cygwin?

SSH Secure Shell only has a problem with emacs; everything else works fine.

Syntax highlight works for bash

Adding to Gilles' line of thought, I'd suggest using Cygwin's MinTTY terminal instead of the Windows console-based one. It uses PuTTY's engine and offers a much, much better experience.

The value of the TERM environment variable should be the same on both systems.

Matching on the window title isn't very reliable. For example, if you're viewing this question in your browser, then wmctrl -a 'emacs' might activate your browser.

You can customize the frame title format with frame-title-format. I use (multiple-frames "%b" ("" invocation-name "@" system-name)). But I don't recommend relying on this in your script.

You can tell wmctrl to look for a window by class with the option -x. That's both simple and reliable.

wmctrl -x -a Emacs

Alternatively, you can make Emacs do the job. This gives you a better chance of picking the “best” frame when there are multiple active frames.
