* Clean up CMake logic
- removed logic to find CppUnit (no longer used)
- removed "dirs" variable used to pass include directories
- removed add_library function (no longer used)
- removed make_executable function
* only used in 2 places (polybar and polybar-msg)
* it was more general than needed, logic is simpler without it
- split polybar into static library and executable
* this allows linking unit tests to the library
* rename library
* add coverage build
- Added a CMake build type "Coverage" that builds C and C++
code with the "--coverage" flag (recognized by both GCC and Clang)
- removed "-Wno-missing-field-initializers" from test flags,
since it didn't seem to be needed any more
- removed logic from tests/CMakeLists to disable "-Werror" and "-pedantic-errors"
since there didn't seem to be any warnings during the build
* fix whitespace
* update travis
* remove O2 from defalt flags
* allow tests to be built by default make target
* disable Werror for debug builds
This patch enables support for nl80211. In case the libnl-genl-3.0
library isn't found, it will fall back to Wext instead.
The library to use can also be manually set with the CMake option
WITH_LIBNL.
The Wireless-Extensions (WE or Wext) are deprecated and long replaced
by cfg80211.
Although Wext isn't used by WiFi drivers anymore, CFG80211_WEXT allows
old tools to communicate with modern drivers by providing a wrapper
API.
The only reason polybar couldn't build without xkb is because the
xkeyboard module's source file was not removed during compilation.
xkeyboard already has an entry in unsupported.hpp
This effectively makes xcb-util-xkb optional
Following [1] to get to this setup.
We setup all the ccache configuration before calling project() because
project will perform compiler checks. This is also why we can't use
message_colored here and print the colors manually
Before ENABLE_CCACHE was not yet defined when we reached the check in
01-core because the option was defined in 02-opts

Before, because of [ -d "$search" ] || search="$(dirname "$search")",
clang-format.sh would search for files to format in the whole repo
(even in the build directory and the submodules)
This now also looks for source files in the tests folder
I have removed the clang-format from clang-tidy.sh because one may want
to run clang-tidy without reformatting
Makes helping with build issues easier as we readily see what versions
are being used.
Cmake already prints the version but only when run the first time and
not on subsequent calls, so the information is often lost
If color output was surpressed, there was no way to tell in the cmake
summary, if a module is actually enabled or not.
Now each module is prefixed with either a "[X]" to indicate it's enabled
or a "[ ]" to indicate it's not
This warning fires here:
/home/travis/build/jaagr/polybar/src/utils/command.cpp:135:46: error: equality comparison with extraneous parentheses [-Werror,-Wparentheses-equality]
} else if ((((*(int *) &(m_forkstatus))) == 0xffff)) {
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~
and as this system macro cannot be changed, let's not turn this into an error
