From: Sam Steingold <sds <at> gnu.org> To: bug-gnu-emacs <at> gnu.org Subject: 26.0.50; poor interaction between flymake and desktop-save-mode Date: Thu, 01 Dec 2016 14:13:20 -0500
When I start Emacs after editing a bunch of Python files,
desktop-save-mode restores them and flymake starts syntax checking
processes in each of them.
However, there is a snag: python virtual environments.
Basically, each python projects uses a separate virtual environments
which includes its own python packages, and, moreover, its own python
and pylint executables(!)
This means that flymake fails to find the epylint executable and
displays a GUI popup(!) for each(!) python file that I edited in the
previous session. Note that this failure should _not_ be fatal (see PS
below).
You can imagine, I am sure, how frustrating it is to have to click on
"OK" (or even hit "esc") 30 times before Emacs actually starts.
The workaround is to customize `flymake-gui-warnings-enabled' to nil,
but this is only one part of the problem.
The necessary fixes would entail:
* flymake should only display GUI warnings in response to a manual
action, not when desktop-save-mode restores a buffer.
* the initial failure in desktop-save-mode should "defer" flymake rather
than "disable" it permanently.
PS. Fixing the following will probably require pyvenv-specific work and
is outside the core Emacs issues, but maybe you have suggestions:
This initial failure, apparently, makes flymake _disable_ itself in all
restored buffers, so I have to re-enable it manually (if & when I notice
that it is not running there).
When I select the Python virtual environment using the pyvenv-workon
command (I might also disable virtual environment altogether or switch
between them &c), the location of the epylint executable should change.
