patrick96 5be532c51b refactor(font): More robust font size calculation 
Originally the size function returned the scaled `size` property for
scalable fonts and the non-scaled `pixelsize` property for non-scalable
fonts. This caused lots of issues when that property was 0 (empty bars,
characters not drawn without warning, see references at the bottom).
This behavior was mostly observed on debian where `size` is set to 0 if
`pixelsize` is set.

We now try to use both properties for both types, but prefering `size`
for scalable fonts and `pixelsize` for non-scalable ones.

This behavior doesn't break existing correct behavior but now never
returns 0. It will always try to fall back to the other property or to
some fallback value if both properties are 0.

I originally thought this could also make font patterns more expressive
by being able to specify the size of scalable fonts directly in pixels
like so:

  Unifont:size=0:pixelsize=20

or to scale non-scalable fonts by forcing polybar to fall back to the
`size` property (which is always scaled):

  Wuncon Siji:pixelsize=0:size=20

But how these two patterns are matched by `fc-match` depends both on the
font and on the distro/fontconfig setup.

Polybar

A fast and easy-to-use tool for creating status bars.

Polybar aims to help users build beautiful and highly customizable status bars for their desktop environment, without the need of having a black belt in shell scripting. Here are a few screenshots showing you what it can look like:

Building from source

Please report any problems you run into when building the project.

Download the polybar-<version>.tar for the version you want to build from the release page, extract it with tar xvf polybar-<version>.tar and go into the extracted folder. There, run the following commands:

$ mkdir build
$ cd build
$ cmake ..
$ make -j$(nproc)
$ sudo make install

There's also a helper script available in the root folder:

$ ./build.sh

For more info, have a look at the Compiling wiki page.

Configuration

Details on how to setup and configure the bar and each module have been moved to the wiki.

Install the example configuration

Run the following inside the build directory:

$ make userconfig

Or you can copy the example config from /usr/share/doc/polybar/config or /usr/local/share/doc/polybar/config (depending on your install parameters)

Launch the example bar

$ polybar example

Running

See the wiki for details on how to run polybar.
