Broken Vim Today

[Ryan G.]

Hello!
I’m not sure if this is the right place to send errors, so if it’s not
could you point me in the right direction and I apologize for any trouble.
That being said, I just updated vim via Ubuntu 16.04 software updater and
immediately after this vim produced many, many lines of errors. Some seemed
to be from my vimrc but many also came from plugins. The most repeated one
was

E10: \ should be followed by /, ? or &

Although there were plenty others too. After a quick search stack overflow
suggested setting nocompatibility and this seemed to fix everything (though
I couldn’t actually use vim to add this to my vimrc because it would spit
errors everytime Ale ran).

If it’s helpful here’s a few other details:

I’ve also attached the error log generated when running vim ~/.vimrc 2>
error.log.To be honest however, I don’t remember what version of Vim I had
installed before the update. Since everything is working now, I’m not
really worried, just thought y’all should know that there may have been
some form of a breaking change somewhere.

Love using your software and thanks for all of the work you do,
Ryan
