Bar is drawn, though only TOP is supported atm. No
screen/display/output selection is possible yet. Mouse *click* works,
but not setting the cursor.
Lots of debug output, crappy code yada yada.
Module plugins are (still) built in <build-dir>/modules.
When installing, f00bar binary is installed to <install-dir>/bin, and
the module plugins to <install-dir>/lib/f00bar.
For this to work, we now also set RPATH correctly. Since the installed
module plugins end up in a different location then when building,
different settings is required for BUILD_RPATH and INSTALL_RPATH.
TODO: optimizations and proper cleanup
* We currently reload the shared library for each *instance* of the
module, and we do it twice; once when verifying, and once when
instantiating.
* The shared libraries are never dlclosed()
This allows us to a) move away from cairo's "toy" API, and b) let the
user specify font options in a single font "name" string:
Serif:size=10:weight=bold:slant=italic
This also allows us to simplify the font code significantly (except
for the fontconfig parts...); the font no longer sets itself in a
cairo surface - font users do that; the font simply returns a
cairo_scaled_font_t.
Furthermore, font_clone() has now been simplified to basically just
refcount the scaled font. I.e. there's no need to run the full
constructor and lookup and instantiate the cairo scaled font again.
State exposed (tag names):
* name: the interface name ("eth0" etc)
* index: the interface index, "ifindex"
* state: operational state (down, up etc)
* mac: the Ethernet hardware address
* ipv4: the *last* IPv4 address added to the interface
* ipv6: the *last* IPv6 address added to the interface
State we monitor (for changes):
* state
* ipv4 addresses
* ipv6 addresses
This allows us to detect plug/unplug events immediately, instead of
having to wait for the next poll event.
Unfortunately, capacity changes do not appear to generate events :(
The ramp particle is configured with a tag name and a list of
particles.
At instantiation time, a single particle is selected from the list,
depending on the tag value and it's minimum and maximum values.
I.e. this particle acts kind of like a progress bar.
