Deprecates not using `polybar-msg` for IPC.
Fixes#2532Closes#2465Fixes#2504
* Create FIFO specific NamedPipeHandle subclass to PipeHandle
* Prototype SocketHandle
* Move mainloop up to main.cpp
* Pass eventloop to ipc class
* Deprecate sending ipc over the named pipe
Unfortunately, we can only show the warning in the polybar log and not
give the user any feedback because the pipe is one-way
* Move eventloop into its own namespace
* Prototype ipc socket handling
* Remove handles from ipc_client
Should be independent from eventloop logic
* Remove ipc clients when finished
* Add tests for ipc_client decoding
* Add callback for complete ipc messages
* Remove template param from mixins
* Move signal handler to new callback system
* Move poll handle to new callback system
* Move FSEventHandle to new callback system
* Move TimerHandle and AsyncHandle to new callback system
* Move PipeHandle to new callback system
* Implement socket functionality in new callback system
* Correctly reset ipc named pipe handle
* Let client close handles in error callback
* Wrap client pipe and ipc::client in connection class
* Better decoder log messages
* Socket path logic
* Fix CI warnings
* Remove UVHandleGeneric
* Fix error when socket folder already exists
* Proof of concept message writeback
* Restructure ipc files
* polybar-msg: Use sockets
* polybar-msg: Better syntax for actions
* Fix memory leak with fifo
After EOF, the pipe wasn't closed and EOF was called all the time, each
time allocating a new pipe.
* Make polybar-msg compile on its own
* Rudimentary writeback for polybar-msg
* Fix payload reference going out of scope.
* Add IPC documentation
* Cleanup polybar-msg code
* Specify the v0 ipc message format
* Close ipc connection after message
* Fix ipc tests
* Properly close ipc connections
* Fix polybar-msg not working with action string
* Write polybar-msg manpage
* polybar-msg: Stop using exit()
* ipc: Print log message with PID
* Add tests for ipc util
* polybar-msg: Print PID with success message
* ipc: Propagate message errors
* Rename ipc::client to ipc::decoder
* Rename ipc.cpp to polybar-msg.cpp
* ipc: Write encoder function and fix decoder bugs
* ipc: Use message format for responses
* ipc: Handle wrong message types
* ipc: Write back error message if ipc message cannot be processed
This only happens for commands and empty actions.
Non-empty actions are not immediately executed, but deferred until the
next loop iteration.
* Remove TODO about deleting runtime directory
The socket file is not deleted after socket.close() is called, only
after libuv executes the close callback.
So we can't just call rmdir because it will probably always fail.
* CLeanup WriteRequest
* Update manpage authors
* Cleanup
* 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

* config_parser: Improve error messages
This commit adds an additional context with configuration file name and
line number to some error messages in the config_parser.
* config_parser: Add file name and line number to invalid_name_error
* config_parser: Update unit tests to avoid crashes on regressions
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(ramp) Implement ramp weights
*Add test for ramp weights
*[drawtypes/ramp] Implement ramp weights
Simply clone `label_t` weight no. of times in the icon list
This helps us not to change any of the calculations.
*Fix silly bug
Forgot to add a hyphen for the `weight` parameter.

*doc: add #1750 to CHANGELOG
* Fix compile error in ramp test
Use std::make_shared.
Add a config parser method which, for now, deals only with escaping the
literal backslash character and logs an error message to inform the user
of the coming change.
The error message includes a properly escaped value for the user.
As a result of introducing an escape character('\'):
- Warn the user of any unescaped backslashes, as they will not be
treated as a literal character in the future
- For now, still treat a single backslash as a literal character
- Treat two consecutive backslashes as a single properly escaped
literal backslash
Also:
- Add documentation about the escape character to polybar(5) manpage
- Add info about the escape character to changelog
- Add testcases for ParseLineKeyTest
- Add new test ParseEscapedValueTest
Resolves: First step in #2354
Improve value parsing
- Take value arg in as an rvalue reference and move parsed value back
- Remove unnecessary if statement
- Rename function
- Improve error message
- Improve function description
- Format
Add escape character documentation to manpages
Add information about the escape character to the polybar(5) manpage.
Add info about the esacape character to changelog

Add tests for escaped_value_parser method
Also remove unsued include statement
Simplify parse_escaped_value in config_parser
Remove unnecessary escaped value generation, so we do not have to keep
track of index differences.

Because we passed a temporary as the logger, it gets destroyed after the
config_parser constructor returns and when the logger is called in
config_parser it operates on a dangling reference.

* 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.

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: #770
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.
