Emacs incompatible with oh-my-zsh?

Question

I'm noticing something really odd in my ansi-term windows on my new Mac, see below:

I am using:

GNU Emacs 27.0.50 (build 1, x86_64-apple-darwin16.7.0, NS appkit-1504.83 Version 10.12.6 (Build 16G1036)) of 2017-11-10

which I installed using brew using:

brew install emacs --HEAD  --with-cocoa --with-ctags --with-dbus --with-gnutls  --with-imagemagick@6 --with-mailutils --with-modules

Note that:

• I see this problem even with emacs -Q.
• I also get this problem when using https://emacsformacosx.com/

oh-my-zsh and termsupport.sh

I only seem to have this problem when I load oh-my-zsh. As I mentioned in a ticket I opened with them, the problem seems to be termsupport.sh specifically. The problem only happens if oh-my-zsh loads that file.

Answer 1

I found the problem. As I mentioned in the ticket, I was setting the variable EMACS myself in .zshenv to help setup PATH. As it happens termsupport.zsh also uses this variable name internally. All I had to do is rename my own variable to something else, and it all now works.
