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

Before it was enabled by default. That means if the constructor fails,
the destructor will complain that the module was not stopped before
deconstructing.
We can't just call stop if module creation fails because the module is
only partially initialized.
* The xworkspaces module should wait for EWMH to become available
Before this change if EWMH wasn't available the xworkspaces module was
permanently disabled. When polybar was started alongside the window
manager e.g. from .xinitrc this caused a race condition between polybar
and the window manager and the xworkspaces module may or may not be
displayed. After this change polybar will wait for EWMH to become
available. This change closes#1915, see that issue for more details.
Curiously this only required the removal of the error condition which
used the be raised when EWMH wasn't available. The xworkspaces module
will show up on the bar as soon as the first EWMH event is processed by
the existing event handling code. I can't argue much about the
correctness of this patch but it seems to work flawlessly in my testing
with xmonad. I didn't test any other window managers. Note that removing
the error condition below which checks that _NET_DESKTOP_VIEWPORT is
available might make this work with pin-workspaces=true. I couldn't test
the effects of that change because I only tested with xmonad and xmonad
doesn't support _NET_DESKTOP_VIEWPORT, so I didn't make that change.
* xworkspaces: Remove check fo _NET_DESKTOP_VIEWPORT
Implementations that don't support it will just return an empty list for
get_desktop_viewports and pin-workspaces won't do anything.
* Update changelog
Fixes#1915

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
Returns a list of key-value pairs starting with a prefix.
If you have in config:
```
env-FOO = bar
env-CAT = dog
```
then `get_with_prefix("env-")` will return
`[{"FOO", "bar"}, {"CAT", "dog"}]`

*doc: add #1750 to CHANGELOG
* Fix compile error in ramp test
Use std::make_shared.
The eventloop no longer uses them. libuv will coalesces multiple
uv_async_send if they happen one after another and this also leads to
coalescing of updates.
This is needed because the handle's lifetime has to be at least the
lifetime of the eventloop since the eventloop requires the handle's
memory during shutdown (for closing the handles).

This adds the 'send' action to the ipc module that can be used to send arbitrary text to the module:
polybar-msg action "#ipc.send.%{F#4444ff}hello%{F-}"
* feat(ipc): allow receiving arbitrary text on IPC socket
Instead of just allowing hook numbers to be executed, the user can
send arbitrary text and the IPC module will put it in the bar. The IPC
payload format is extended to accept an arbitrary string if the first
character after the module name is ':'.
polybar-msg hook test :'%{F#4444ff}hello%{F-}'
Fix#2455

* Rename toggle_visible method to match
`action_toggle_visible` -> `action_toggle_visibility`
Matches with `EVENT_TOGGLE_VISIBILITY`
* Update CHANGELOG
* Revert #2320 IPC commands
IPC commands are no longer necessary now that the actions are
implemented. Changed some method permissions as well to reflect this.
* Add logging and change action names
- `module_toggle`
- `module_show`
- `module_hide`
Delineate common actions to all modules with a `module_` prefix (for
future actions too)
* Update documentation
While it shouldn't happen with compliant WMs, it was possibe to crash
polybar with _NET_CURRENT_DESKTOP >= _NET_NUMBER_OF_DESKTOPS and this
should not be possible.
Includes polybar/xpp#31
Fixes#2398
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.
The renderer now only stores the positions of the actions because that
is specific to the renderer and because the actual position can only be
finalized after all the rendering is done because intitially the
positions are relative to the alignment and not the bar.
The variables storing the current colors, attribute activations and font
were only used in a single place and can easily also be read from the
context.
This allows us to remove a lot of the state of the renderer.
* add reverse-scroll option for xworkspaces module
* move use of reverse-scroll option to when producing scroll action
* documented xworkspaces reverse-scroll option in changelog
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

- Take value arg in as an rvalue reference and move parsed value back
- Remove unnecessary if statement
- Rename function

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
Modules can now also be shown and hidden using ipc commands:
$ polybar-msg [-p PID] cmd hide.mymodule # Hides module mymodule
$ polybar-msg [-p PID] cmd show.mymodule # Shows module mymodule
$ polybar-msg [-p PID] cmd toggle.mymodule # Toggles visibility of mymodule
* Hopefully implement visibility checking
* Implement hide command
* Implement `show` and `toggle` commands
* Refactor and add some logging
* Run style checks and update CHANGELOG
* Get around unused parameter warnings
* Change `set_visible` to return nothing
* Make errors more informative

Each major target of polybar can now be enabled/disabled while
configuring (even polybar itself).
The cmake code specific to each target will only run if the target is
enabled.
This allows us to for example just build the documentation without
having to run all the cmake code related to compilation or having the
polybar dependencies installed (other than sphinx).
They were required before, but could technically be deactived (the
compilation would fail, but configuration was possible).
The WITH_XRANDR and WITH_XCOMPOSITE now no longer appear in the cmake
part. It still appears in the source code, but is always set to 1
Fixes#1536
* Add variant support to xkeyboard layout label

* Run style checks, I guess?

* Return nothing if there is no variant
* Update CHANGELOG
* 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
The change in #2270 accidentally broke how we access module types.
module<Impl>::TYPE always points to the module superclass and it thus
accesses its empty TYPE field.
This mainly broke legacy action handling.
Ref #2270
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
For some reason when passing some non-const strings to convert, the
convert(T&& arg) method was used instead of the one specialized for
strings.
This caused an error in clang because you can't pass objects with
non-trivial types to varargs functions.
The best solution I found was to just add a specialized function for
non-const strings.
If two WM events arrive withing 25ms of one-another, the second one does
not trigger a bar update.
The module state is still correct, it is just not reflected in the bar.
This somehow caused updates being swallowed in fluxbox, but only after
PR #882 was merged, even though that 25ms restriction existed long
before that.
Fixes#2272
Since 3.5.0, we use m_interval for a modulo operation, this crashes the
bar if the interval is 0. A non-positive interval shouldn't be allowed
anyway, so we now throw an exception in that case.

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
New config option `speed-unit = B/s` will be used to suffix the upload and download speeds.
* mod::network: udspeed-unit to set network speed unit suffix
* Changed udspeed-unit to speed-unit
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.
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.
All modules now expose their actions as public static constants
Issues: The menu module no longer closes when an item is clicked (before
it would intercept any executed command and look if it matches one of
its exec commands)
This allows us to identify module by their type and it is also better to
store the module type as part of the module instead of having it
hardcoded in factory.hpp
