This patch introduces a new 'set_from_resource' config directive which
allows defining a variable by retrieving its value from the X resource
database. This avoids having to configure a color scheme in multiple
files. The directive takes an additional fallback value which is used
in case the resource cannot be found or during config validation where
no X connection is available.
Furthermore, this patch includes the following changes:
- If the same variable is defined twice, we now properly overwrite the
value of the assignment rather than inserting two variable definitions
with the same key.
- We now depend on xcb-util-xrm to query the resource.
- Increase the buffer size for variable / resource assignments.
fixes#2130
The resulting packages are pushed to Debian repositories hosted on
bintray.com.
This is the first step to move away from our custom buildbot setup (see
https://i3wm.org/docs/buildbot.html for details on that) towards
infrastructure which is more standard (travis) and in the open.
