Subject: Escaping a string for substitute-command-keys
Date: Thu, 3 Oct 2019 09:52:31 -0400	[thread overview]
Message-ID: <14423aa7-36c3-9ab7-6483-d43624f99e17@gmail.com> (raw)

Hi emacs-devel,

I think I've seen a thread about this in the past, but I can't find it. What's the expected way to escape a string before its fed to substitute-command-keys, so that substitute-command-keys reconstructs the original string?

The reason for this question is that since 2015 Emacs has been calling substitute-command-keys on help-echo messages, which breaks flycheck and flymake (a simple way to reproduce the issue is to enable flymake in a Python buffer containing just xxx and to hover over the xxx with the mouse: Emacs shows a tooltip containing "Undefined name ’xxx’").

So, what's the right way to escape a string to be fed to substitute-command-keys?  Alternatively, is there be a way to disable the transformation for a particular help-echo string, rather than forcing an unnecessary rountrip?  Maybe we could add a text property, so that if a string is tagged with a 'text-quoting-style property that style is used instead of the default one?

Thanks!
Clément.
