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
The PYTHONPATH env variable needed to be removed because it was messing
with pip and cpp-coveralls
Unfortunately adding the '-e build' to coveralls doesn't work to exclude
source files in the build directory, as it won't collect any data then.
If at some point, we have source files that are used by the tests
somewhere inside the build folder that isn't covered by the exclusion
rules, we'll need to add it here
googletest (gtest) is more feature rich than the current implementation
which only provides expect() which is basically an assertion. It is also
quite intuitive to use, this can be seen in the rewrite of the
command_line test where EXPECT_THROW replaces a whole try-catch block.
I have also moved the source files the test depend on to be linked in
CMakeLists.txt instead of including them directly because include .cpp
files is bad.
The two x11 tests were removed because they were written two years ago
and a lot of the things they depend on, don't actually exist anymore in
polybar (I think we switched to xpp after those tests were written)
Tests are now compiled with the gcov lib which can be used to provide
test coverage in a second step
This is basically a major rewrite of the .ycm_extra_conf.py file that
ycm uses to determine what compile commands it should use for a file.
But the basic purpose is for it to use the generated flags in
build/compile_commands.json that is generated by cmake for as many files
as possible.
Before it always used the hardcoded default flags which would not always
work for all files.
Now it gets the proper flags for all files I tested.
In the src and tests folder the flags are already generated by cmake
In the include folder it tries to use the flags of the corresponding
source files in the src folder
xcb-proto 1.13 finally introduces the eventstruct key that made polybar
not compile. The fix isn't in any release yet, this checks out the
newest xpp commit with the fix during compilation until we release 3.2.0
Fixes#1090
Polybar itself doesn't depend on jsoncpp at all, only i3ipcpp does and
it has the jsoncpp 1.7.7 source code in its repo, if a too low jsoncpp
version is found.
