The following modules used functions from the ‘m’ (math)
library (e.g. round()), but didn’t explicitly link against it. This
caused build failures when no other plugin that _did_ link against ‘m’
was enabled.
* cpu
* mem
* pulse
* pipewire
* foreign-toplevel
Closes#239
Before this patch, the cpu module instantiated a single particle (the
‘content’ particle), with one tag ("cpu") representing the total CPU
usage, and then one tag (cpuN) for each core.
This makes it cumbersome to configure, since you need to explicitly
reference each cpuN tag to get per-core usage.
This patch rewrites this, so that ‘content’ is now a template. It’s
instantiated once to represent the total CPU usage, and then once for
each core.
Each instance has a "cpu" tag, representing the CPU usage of that
core (or total usage). It also has an "id" tag. The ID is 0..n for
actual cores, and -1 for total usage.
This means you can do something like this in your config:
- cpu:
content:
map:
conditions:
id < 0: {string: {text: "Total: {cpu}%"}}
id >= 0: {string: {text: "Core #{id}: {cpu}%"}}
Closes#207
Without this change yambar can't be installed/used without libmpdclient even for
people who do not use MPD. Let's make this optional.
We could put the optional module summary in the module meson.build but we'd have
to move summary() in main meson.build so that they appear in proper order.
* Bind the foreign-toplevel-manager object *after* the first round of
global objects. This ensures we bind all pre-existing wl-output
objects before binding the toplevel manager. This is important, since
otherwise we wont get any output_enter() events for the initial set of
toplevels.
* Bind xdg-output-manager, to be able to bind xdg-output objects for
each wl-output.
* Add xdg-output-listener to each wl/xdg-output, to be able to get the
outputs’ names.
* Add a list of outputs to each toplevel. The output_enter() event
adds to this list, and output_leave() removes from it.
* Add option ‘all-monitors’. When not set (the default), toplevels are
only included in the generated content if they are mapped on the same
output as the bar itself. When *not* set, all toplevels are always
included in the generated content.
* ‘content’ is a template; the module returns a list of toplevels,
each one instantiated using the content template.
* Each toplevel has 6 tags:
- app-id (string)
- title (string)
- maximized (bool)
- minimized (bool)
- activated (bool)
- fullscreen (bool)
To show the application name and title of the currently active window,
one can do:
- foreign-toplevel:
content:
map:
tag: activated
values:
false: {empty: {}}
true: {string: {text: "{app-id}: {title}"}}
This module exec’s a script (or binary), specified by the ‘path’
attribute in the configuration.
It then reads tags from the script’s stdout.
The format of the output is:
tag|type|value
tag|type|value
<empty line>
I.e. the script writes N tags followed by an empty line. This
constitutes a transaction.
When a new transaction is received, its tags replaces *all* previous
tags.
The ‘river’ module depends on generated protocol sources. These are
normally provided, indirectly, by the Wayland bar backend. But when
building plugins as shared modules, the plugins no longer depend on
the bar, and thus ‘river’ fails to build.
Fix this by doing two things:
* **Remove** the ‘river’ protocol from the ‘generic’ Wayland protocols
* Explicitly add both the generic and the ‘river’ specific protocols
to the ‘river’ module.
All decoration, particle and module interfaces now takes a
pixman_image_t parameter, and all drawing is done using pixman APIs.
The wayland/xcb backends implement a new interface functions,
get_pixman_image(), that should return a pixman image instance that is
suitable for rendering.
In the wayland backend, the image uses the same backing data as the
cairo surface.
In the XCB backend, we create a new image each time, and then blit it
to the cairo surface at commit time.
We subscribe to Sway's 'input' events, and use these to expose input
devices' active XKB layout.
The module is configured by specifying a list of 'identifiers'; these
are the input devices (keyboards, typically), that we'll be
monitoring. All other input devices are ignored.
'content' is a template, and the module will instantiate a dynlist
with a 'content' for each *existing* input found in the 'identifiers'
list.
We also monitor for device 'added' and 'removed' events, and update
our internal list of existing inputs.
This means the user can configure a set of identifiers, and only those
that are actually present will be displayed. If a device that is
listed in the 'identifiers' list is added, it will be displayed. If it
is removed, it will no longer be displayed.
