Updated for style.

- Remove <errno.h> because related functions are in util.c now
- Remove corresponding <string.h> if not used otherwise
|
|

This drops a lot of code and even though we are using a common function,
the specification of only the needed things keeps it very efficient and
even more efficient in memory and time than the previous solution.

On OpenBSD the backlight percentage cannot be retrieved in a simple way.
The only two solutions we are aware of for now are:
- reading from /dev/ttyC0: which isn't possible without changing
permissions or running slstatus as root
- linking against xcb-xrandr: which is bloat and does not work in every
case appearently
This reverts commit 37724ac2c3f496f4736223d0d8e5d8fecb933590 for now.

- Get rid of camel-casing
- Don't use all-caps for variable names
- use LEN()-macro
- use strncmp() rather than strstr() for prefix-checking
- clean up the tokenizer-loop and don't use copies
- make the loop more readable by separating different breaking
conditions
- stricter error-checking and cleanup
- store the layout directly with bprintf rather than having
a separate buffer

Adding a new keymap component that will
indicate the current keyboard layout (language)
and variant if any was set. I use the
standard X11 XKB APIs to retrieve and parse
the xkb_symbols set with setxkbmap.

At the moment linux only, but will add support for OpenBSD as well.

Thanks to Hiltjo

Add a return value so we are able to check any errors and actually fail
when there has been a critical error instead of carrying on uselessly.
|
|
Now only one function, fmt_human, takes an additional argument "base".
|
|
In a later commit something like that will be enabled for every
component

- Line length
- Spacing and indentation
- No explicit checks for NULL

This is a first step to decouple formatting from information because of
two reasons:
1. The components should only gather and return the values by design
2. Fine grained user control should be a focus
Scaling will be implemented in a different way in a later commit.

On some laptops (mostly thinkpads), the remaining time may be
expressed in µWh using energy_now and power_now files rather than µAh
for charge_now and current_now.
Add pick function to conditionally select appropriate one.

free the interface list before returning from the function

These functions take the raw number and a unit and automatically
print it out "scaled down" to a proper SI-prefix, for powers of 2
and 10 respectively.
Apply them to the 2-power cases and keep the 10-power for a later
commit.
|
|
Units should be added to the corresponding numbers
|
|
First dividing by interval before multiplying with 1000 decreases the
precision by +-(interval - 1) * 1000, as interval arithmetic always
applies the Gauß-function to the result.
This is not necessary and simply reordering the operations mitigates
this.

Within the components, snprintf() was unchecked and had inefficient
calls in some places.
We implement esnprintf() that does all the dirty laundry for us
and use it exclusively now.

implemented additional error condition for openbsd netstat in case the
interface could not be found in the interface list or if_data is not
readable.
|

implemented the netspeed functionality for openbsd.
furthermore the static keyword was removed of the interval variable in
config.def.h for usage as extern variable.
