We had a check that restricted config files to "regular files".
This check was to restrictive as it didn't allow for things like:
```
polybar -c <(gen_config)
gen_config | polybar -c /dev/stdin
```
Now, polybar can easily read config data from stdin.
* Handle relative includes
We change to the directory of the given config file before parsing.
This allows us to handle relative includes.
TODO: Maybe improve the name of the change_dir() function.
* Fix unused result warning
* Add `relative_to` parameter to expand()
If the path is relative, we resolve it by prepending
dirname(config) to the path.
Add dirname() - Returns the parent directory of the file or an empty
string.
* Resolve relative paths
Handle paths relative to the current file being parsed.
* Remove unneeded change_dir()
* Fix expand()
`is_absolute` is calculated after we expand the path.
`relative_to` must be a directory.
Add test for expand() with relative paths
* Recalculate `is_absolute` after expanding `path`
* Add more file_util::expand tests
* Add changelog

The previous CAST_MOD(Impl) for the action_router constructor was
illegal because `this` is not yet of type Impl (because the subclass
constructor has not run yet).
The action_router now accepts std::function for its callbacks.
Fixes#2519
Fixes#1978
* Move tail and non-tail handler to method
Defining them in the constructor is ugly.
* script: Iterate over defined actions instead of fixed list
* Separate running logic and lock m_output
* Include POLYBAR_FLAGS in linker flags
* Stop using m_prev in script_runner
* Join module threads in stop function
Joining in the destructor may lead to UB because the subclass is already
deconstructed but the threads may still require it to be around (e.g.
for calling any functions on the instance)
* Cleanup script module
* Update changelog
* Remove AfterReturn class
* Remove m_stopping from script module
* Fix polybar not reading the entire line from child process.
For every `readline` call we created a new fd_streambuf. This means once
`readline` returns, the streambuf is destructed and and pending data in
its temporary buffer discarded and we never actually read it.
* Remove unused includes
* feat:add tokens to display memory in MiB when GiB val <= 1.0 (#2472)
* fix: correct swap_used calculation
* fix: pass variable by reference rather than by value
* fix: add precision arguments to filesize_gib_mib(); better condition
* doc: add #2472 to CHANGELOG
* fix: missing default argument values
* Apply suggestions from code review

When `pin-workspaces` is set to true using `show-urgent` will show
urgent workspaces on the bar even when the workspace is not associated
with the current monitor.
* build: Add -Wsuggest-override
We should always use the override specifier when overriding virtual
functions. This helps prevent errors when a subclass tries to create a
function with the same name as a virtual function in a super-class but
with a different purpose.
* clang-format
* Upload logs on failure
* Add override to unsupported.hpp
* cmake: Make -Wsuggest-override flag conditional
* module: Implement proof of concept action router
Action implementation inside module becomes much cleaner because each
module just registers action names together with a callback (pointer to
member function) and the action router does the rest.
* Make input function final
This forces all modules to use the action router
* modules: Catch exceptions in action handlers
* Use action router for all modules
* Use action_ prefix for function names
The mpd module's 'stop' action overwrote the base module's stop function
which caused difficult to debug behavior.
To prevent this in the future we now prefix each function that is
responsible for an action with 'action_'
* Cleanup
* actions: Throw exception when re-registering action
Action names are unique inside modules. Unfortunately there is no way to
ensure this statically, the next best thing is to crash the module and
let the user know that this is a bug.
* Formatting
* actions: Ignore data for actions without data
This is the same behavior as before.
* action_router: Write tests
* refactor(color): Use enum class for color type
* Add testcases for tag parser
* Make tag parser a pull-style parser
Being able to parse single elements at a time gives us more fine-grained
error messages, we can also parse as much as possible and only stop
after an exception.
* fix(color): Parser did not check for invalid chars
* tag parser: First full implementation
* tag parser: Fix remaining failing tests
* tag parser: Replace old parser
* tag parser: Treat alignment as formatting tag
Makes the structure less complex and the alignment tags really are
formatting tags, they are structurally no different from the %{R} tag.
* tag parser: Cleanup type definitions
All type definitions for tags now live in tags/types.hpp, the parser.hpp
only contains the definitions necessary for actually calling the parser,
this shouldn't be included in many places (only places that actually do
parsing). But many places need the definitions for the tags themselves.
* Rename components/parser to tags/dispatch
* tag parser: Cleanup
* Add changelog
Since the forked processes are still our children, we need to wait on
them, otherwise they become zombie processes.
We now fork twice, let the first fork immediately return and wait on it.
This reparents the second fork, which runs the actual code, to the init
process which then collects it.
Ref #770
It was not quite clear how try_apply_alpha should behave if the given
color was not ALPHA_ONLY. The implementation just returned 'this'.
However, the build relied on it returning the given color.
This broke all bg and fg settings in the entire bar.
To clear this up, we switch this around take the alpha channel of 'this'
and also return 'this' if it isn't ALPHA_ONLY.
Fixes#2255
Shell commands triggered from action tags used to block polybar until
they finished.
Since we are not actually interested in the output of the commands, it
makes sense to run them completely detached from polybar and have
polybar not block when executing these commands.
Now the spawned child processes no longer get killed when polybar
exits. This is fine because polybar is not responsible for these
processes since they were explicitly started by the user through click
commands.

Ref: #1680
The intent is for every color to be stored in a rgba instance
The rgba class now stores the color in a 32 bit integer to save space
This also removes the unused class rgb and moves everything else into a
cpp file.
Many functions also had weird template parameters. For example
alpha_channel<unsigned short int> would give a 2 byte number with the
alpha channel byte in both bytes.
color_util::hex would return a hex string with alpha channel if unsigned
short int was given and without if unsigned char was given. Even more
curiously those parameters were passed to *_channel and the result
nevertheless truncated to 8bits.
Only modules can now be action handlers.
This also slightly simplifies the controller because we don't need to
keep track of input handlers, we can just use the module list.
The github module only authenticate by query string, and this method is deprecated:
https://developer.github.com/changes/2019-11-05-deprecated-passwords-and-authorizations-api/#authenticating-using-query-parameters
There is no reason to remove it before the method stop working, so I've made possible to the user choose which authentication method he will use:
* The parameter token remain unchanged.
* If the parameter user is passed then the module will use the not deprecated method, passing user and token on the body of the requisition. Otherwise the module will use the deprecated method.

Fixes#2002
Since all of polybar is built at once, there is no chance that this is
ever linked to an object that was compiled with another `-std=`
