* Add toggle_visible action
* Add set_visible and set_invisible actions
* 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
* Add wm-restack=generic to lower polybar to the bottom of the stack
Previously wm-restack only supported bspwm and i3. Both have a special
top-level window that polybar detects and places itself directly above.
This patch adds wm-restack=generic which simply lowers polybar to the
very bottom of the stack. This option was tested and confirmed to work
with xmonad which doesn't have a special top-level window and therefore
doesn't require special handling like bspwm and i3.
Fixes#2205
* Update src/components/bar.cpp

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 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

* 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

The intention was to remove tags that won't have an effect and join
together consecutive tags.
However the patterns used can just as well appear in regular text, so
this can replace characters inside user defined text and not just
formatting tags.
Fixes#2331
* 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
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.
Pre 3.5.0, any key starting with 'inherit' was treated as an inherit
directive. This allowed for multiple inheritance even though it was
never inteded in that way.
3.5.0 removed that bug/feature by doing a strict check against 'inherit'
It seems people were relying on this behavior, so we are adding it back.
However multiple inheritance with multiple keys is also deprecated in
favor of the `inherit` key now supporting multiple space separated
sections.
This is because the config doesn't have a key order, but inheritance
does depend on the order the different section keys are copied over (if
multiple inherited sections define the same key).
Fixes#2269
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
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.
Some actions have data attached (e.g. xworkspaces-focus=N), the
forwarding logic now matches the keys in the legacy_actions map as
prefixes and everything afterwards is considered additional data and
appended to the new action string.
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)
All the information about which action has to be delivered to which
module is kept in once place to make cleanup easier once the deprecated
actions are removed.
Right now only the date module is added as a proof of concept.
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
Action strings now have the form '#MODULE#ACTION'
For example to trigger the action 'toggle' in the 'module/date' module
one would now use '%{A1:#date#toggle:}'
With this action strings can now be uniquely assigned to one module.
Fixes#1172
If an input is enqueued as a response to an input, the new input will be
swallowed because it will likely be enqueued less than 30ms after the
original event.
This is not something that is an issue right now but it is required to
finish #1907 where, in order to close the menu after a click, the menu
module gets an exec action that closes the menu and adds a command to
the event queue.
The setting also isn't too useful since it will just break polybar input
handling if inputs arrive too fast instead of (possibly) slowing down
the bar.
It is useful for people to see what config file polybar loaded.
For debugging font issues people almost always need to check what fonts
polybar loaded, for that they need to run polybar with info logging. Now
this information is always provided. This requires an update in the font
wiki page.
A warning implies something went wrong and (possibly) the user should do
something about it. However, warnings are not always used this way.
For example:
* When a fallback value for a `${..}` reference is used, this shouldn't
produce a warning (or notice) since using fallbacks is not something
bad.
* pulse telling you that it uses the default sink because no sink was
specified also does not warrant a warning (even notice may be too
high).
* Whenever polybar shuts down it produces a "Termination signal
received..." warning. Since there isn't a more proper way to shut down
polybar, it should not produce a warning. Same argument for a
`screenchange-reload`
Before it would only reload if the size changed and even that was
reliable since the method relied on the order of the monitor list.
Now if the monitor list differs in any way (pos, dimension, primary,
output, name) a reload is issued
Removing monitors is not really necessary when selecting the monitor
where to render the bar or choosing the backlight. Since both monitors
occupy the same coordinates rendering can be done on both and it's
better to give people felxibility for the backlight.
Fixes#1191
Premature optimization that tried to cache monitors but the cache did
not take into account the parameter values.
The call `get_monitors(..., ..., false, true);` would get all connected
and unconncected monitors a subsequent call
`get_monitors(..., ..., true, false);` would get back the same list of
monitors even though it requested only connected monitors.
Additionally `get_monitors` is never called periodically so the
optimization really didn't help much.
Functionality-wise reverts the changes from #1534
In #1907 we have decided to allow the same module to appear multiple
times (and deliver actions to all matching modules). But since that PR
will likely take longer to get merged, I want to remove the error from
polybar because the message it prints isn't really true anymore.
The old code didn't really work when the right block was pushing against
the center block. Also `fixed-center` wasn't properly defined. I have
now fixed it to the following:
* `fixed-center = true`: The center block stays at the center of the bar
whenever possible. It can be pushed to the left if the right block takes
too much space and to the right if the left block takes too much space
* `fixed-center = false`: The center block will be in the middle between
the left and right block whenever possible. If there is not enough space
between those two, the center block will be directly to the right of the
left block and pushes out the right block
The issue was that it used the position of the center module to
calculate the leftmost possible position of the block. However, if the
center module is empty that position is disastrously wrong.
Fixes#591Fixes#1903
the `node` and `node_repeat` were never called with the optional
parameter add_space. And its default value is false, so the
corresponding code was never used.
I think in general it is better to just have the user of those functions
call `builder::space` when they need to instead of adding more
complexity to the `node*` functions.

None of the payload fields seem to be used. They were the only place
where EVENT_SIZE was used and why it had to be a macro (no variable
length arrays).
Some people use text modules instead of the `separator` key in the bar
section to better configure the separator (colors, fonts).
Since we disallowed the same module being used multiple times in #1534,
this will now print an error message.
This should help with this a bit.
Ref #1913
Some WMs like i3 discard position information when unmapping the bar and
because of that the bar would be at the wrong position after being
remapped.
