* Patch to support Lua 5.3.
* Fix Lua header include directives in tolua++.h
Use angle bracket rather than double quotes when including Lua headers in the tolua++ header. This fixes a problem on systems that default to a Lua version newer than 5.1 and install the tolua++ header to the same directory as newer Lua headers.
As there are (usually) no Lua headers in the same directory when building tolua++ itself, the preprocessor will look to the include directories passed to the compiler, one of which would be the Lua 5.1 include directory, and tolua++ will build with those (correct) headers. Then the tolua++ header is usually installed in the default include directory, alongside the newer Lua headers, which you wouldn't expect to cause any trouble.
But it does cause trouble when trying to build other programs that include the tolua++ header, because now the preprocessor does find Lua headers in the same directory as the tolua++ header, which are the newer (incorrect) headers. Now the program will either fail to compile, because it doesn't support the newer headers, or fail to link with the tolua++ shared object because they were compiled against different Lua headers.
Using angle brackets instead of double quotes in the include directives will fix the problem, because then the preprocessor will look to the include directories passed to the compiler first.

* Remove email notifications.
* Update travis build.
* Build shared and static libs.

With this change, support for Lua 5.1 is dropped.
This resolve #116.
* Add some comments to clarify the toluapp handling.
* Add minor sonar fix.
* Get rid of silly `if (not ...` exp.
* Apply code fixes from sonar.
* Build fix.
* Apply more fixes from sonar.
* Apply more fixes from sonar.
* Apply more fixes from sonar.
* Fix race condition in gw_info handling.
* Fix a couple potential nullptr derefs.
* Fix font handling without x.
* Fix regression in output to ncurses with X disabled.
* Apply some formatting/code smell fixes.
* Try to amend #31
* BUILD_WLAN should be available for all OS.
Keep BUILD_WLAN OFF by default for compatibility reasons.
* WLAN-related variables should be available for every OS.
There are some problems (probably null-dereference)
* Fix $wireless_essid crashing conky if no argument provided.
Conky wasn't parsing the argument of the variable as it should, thus wasn't allocating the `dev` member variable.
Also fix some documentation stuff.
* Improve `get_freq` #20
Using the Intel® Power Gadget API (https://software.intel.com/en-us/blogs/2012/12/13/using-the-intel-power-gadget-api-on-mac-os-x) we can now get actual Core frequency and not the constant factory one.
Though, for some weird reason the API gives the same freq for all Cores, thus the |cpu| arg becomes useless.
* Oops, this accidently slipped in
* Introduce BUILD_IPGFREQ build option
This build option has been introduced for one particular reason:
On macOS getting current core-frequency is not supported by the APIs. A solution is to install Intel's ® Power Gadget which comes with an .app, a Framework and a kernel-extension. Though, this may trouble some alot, thus introduce BUILD_IPGFREQ.
* Forgot static here.
* Some improvements for get_freq again.
Fix frequency not printing correctly (I wasn't using the divisor)
Add more guards.
* Setup cmake files and project code for Objective-C code #17
We want to use CoreWLAN framework.
* update_cpu_usage() now supports multiple cores
Also, some cleanup.
* Updated default conky config to monitor Mac Networking
* Made Mac Friendly BuildOptions and generic default conky configs
* Undid Xdamage config and cleaned up previous IF statements
* Re-Added XDamage fix
* Finish up the algorithm. I think its now correct. Closes: #33
* Cleanup macro and introduce a no-op free_cpu() function for ALL cpu-related variables
free_cpu() must be implemented for every OS and on all except macOS its a no-op function.
* Reformat, add empty comment.
- For an AMD FX(tm)-6350 Six-Core Processor the file '/sys/.../present'
reports "0,3-7". I assume that chip is really an 8-core die with two
cores disabled... Presumably you could also get "0,3-4,6", and other
combos too...
Per manpage of mount(1) in newer util-linux:
The programs mount and umount traditionally maintained a list of
currently mounted filesystems in the file /etc/mtab. This real mtab
file is still supported, but on current Linux systems it is better
to make it a symlink to /proc/mounts instead, because a regular mtab
file maintained in userspace cannot reliably work with namespaces,
containers and other advanced Linux features.
In most new Linux (e.g. Debian) /etc/mtab is already symlinked to
/proc/mounts.
See

for the gory details.
I ran cppcheck on a whim while trying to debug #103 and it found these possible
memory corruptions. They all seem to be buffers that were made one byte too
small (leaving out the byte for the C-string null terminator).
When we parse /proc/<pid>/* in order to populate the process struct, it isn't
necessary to try to remove any instance of "kdeinit: " anymore (IMO). Here is
why:
* If the user chooses to display full command lines (top_name_verbose = true),
then we should show full command lines without stripping useful info.
* The new basename entry already has a stripped down command. For example, if
the command line is "kdeinit4: kded4 [kdeinit]", then basename is "kded4".
* The code does not account for "kdeinit{4,5}: ", resulting in undesired
behavior, e.g. "kdeinit4: kded4 [kdeinit]" becomes "kdeinit4:".
* The code does not account for NUL separated arguments.
* The code opens /proc/<pid>/cmdline a second time, so this commit is a minor
optimization.
I think it is best to remove this code altogether. If anyone disagrees, please
comment or send me some hate mail with reasons why we should keep it. The commit
is easy enough to revert. :)
Since we now store a full command line for each process, a few problems are
apparent. For example, the names displayed by ${top ...} are verbose. This has
been partially addressed by the top_name_verbose option, but it is broken
whenever an executable name contains spaces. Another example is ${if_running},
which only matches the input if it exactly matches the entire command line.
This commit adds a basename (i.e. executable filename) entry to the process
struct. The intention is to store the executable filename from /proc/<pid>/stat,
which was the old 1.9.x behavior. This way, we have the best of both worlds.
Those who like the full command line can have it, and those who prefer the old
way can be satisfied too.
According to proc(5), /proc/<pid>/cmdline is supposed to have a NUL between each
argument, plus an additional NUL at the end. Instead of replacing each NUL with
a space, just replace the ones between arguments and ignore the rest.
Partial fix for #121.
If BUILD_IPV6=ON (default), but the user has disabled ipv6 support
in the kernel using the parameter ipv6.disable=1, then conky fails
to open /proc/net/if_inet6. This leads to a segfault when conky
calls fclose(file) regardless. This fix simply moves the fclose call
into the preceding if statement.
It now reports only reclaimable memory, by excluding shared memory,
and including the reclaimable part of the SLAB cache.
So '$mem' with 'no_buffers yes' is now the "really used" (unreclaimable) memory.
And when reaching OOM conditions, conky will always report high memory usage.

In particular:
- Don't call get_battery_perct() recursively.
- Use define for length of string holding battery name.
- We can use strcpy() since bat is zero-terminated.
Before, in the case of an unknown battery status (which often happens on my Sony VAIO laptop after waking from sleep), the buffer would be unterminated.
(Although, this memmove trick is a bit odd. It would probably be better to remove the memmove's and put a single buffer[1] = '\0'; at the end of the function).
Conky takes process names from /proc/<pid>/stat and it's limited to 16
chars in kernel. That obviously makes top_name_width option to work only
for decreasing name length. To obtain longer names we parse
/proc/<pid>/cmdline.
Not every process has cmdline, so we take both process names and choose
one we want to use. Like this:
- Get process name from /proc/<pid>/stat
- Get process cmdline from /proc/<pid>/cmdline
- Transform cmdline to a bit simpler form(i.e. "/usr/bin/python
/usr/bin/terminator" to "python /usr/bin/terminator"), keeping
the arguments(might be changed easily)
- Choose the one that is longer and use it
