Last night I finally managed to get a working build of the Snippet Pixie snap that pretty much works as hoped, but there were a couple of things I had to change in order to get autostart working that I thought it might help others to mention here.
There’s a couple of wrinkles due to naming.
The snap is called
snippetpixie and uses that in the
apps: entry, but the binary and canonical name for the app (as used in
meson build etc.) is
com.github.bytepixie.snippetpixie, and that’s the app’s “ID” too. It’s a GTK app built with Vala, initially for elementary OS.
This means the
.desktop file is usually called
com.github.bytepixie.snippetpixie.desktop. So in the app it uses this as the desktop file name when trying to copy and fix it up to create an
autostart version, but the
DesktopAppInfo class failed to find the file by that name.
snapcraft takes that
com.github.bytepixie.snippetpixie.desktop file and renames it to
snippetpixie_snippetpixie.desktop at some point (I think install time by
snapd), making some changes to the
Exec line along the way.
This means the
DesktopAppInfo class doesn’t recognize
com.github.bytepixie.snippetpixie.desktop as valid.
In the end I had to add specific code for running as a snap to change the desktop file name to look for, and also be careful about the way the
Exec line is changed for the new autostart version to carefully insert the required
--start param in the altered command line instead of blindly changing it to
You can see some of the altered (not very clever, but it works) code in snippetpixie’s
Hope this helps someone else having troubles getting autostart to work for a snap.
I guess I’m also offically announcing that there’s candidate availability of a snap for Snippet Pixie!
It can be installed from the candidate channel with…
sudo snap install snippetpixie --classic --candidate
