CPU percent width is 5, which accommodates the maximum possible width
(100.0). When it's at full width, though, the percent string runs right
up against the item before it.
When the graph is enabled, running up against the graph just looks
strange, but still readable ([ |||]100.0%). With the graph disabled
(-g 0) though, it runs into the memory widget, which makes both of them
very difficult to read (11/32GB100%).
This commit adds one space to the CPU percent width. It offsets
a non-pegged load by one, but it ensures there's always at least one
space to separate the widgets.
The color preceding of the space preceding the load is
made to be consistent with the load color instead of the default. This is
consistent with the CPU percentage color and easier to read.
All the platforms were using identical logic based on getloadavg() function to
get the load avg stats (except linux, which was using sinfo struct, but can use getloadavg() function). I've noticed this while working on NetBSD port.
Also: fixed a typo on freebsd.
Since the headers for cpu, memory and load functions are virtually the same for
all platforms, I've decided to move them into common/ dir and do some
refacotring:
* removed per-platform header files
* implemented get_cpu_count() function across all platforms. We are using it cpu
on every platform, yet not on every one this was implemented as a separate
function.
* removed platform detection through preprocessor from main: we don't need this
there anymore, since the headers are common for all platforms. CMake will
handle setting of correct source files for us now.
* Unified used defines for CPU states across all platforms and made linux use
them. Added some platform detection to cpu.h in order to set them correctly
across the platforms.
* moved getsysctl.h to common/ dir, since it's used on Net and Free BSD, and
thus become a common include.
On 64bit system KERN_CPTIME systctl gets returned as 64bit uint.
On 32bit system it's returned as 32bit uint. This is not documented anywhere
(or maybe I've missed it). I've added preprocessor test for 64bit system.
- Removed OpenBSD stuff from freebsd port
- Renamed bsd folder to freebsd since now it contains only
freebsd-relevant files.
- Changed CMake instructions to account for bsd port changes
- modified main source file to account for openbsd port
