Closes#5605
Text Subpixel antialiasing is :
- FreeType makes glyph bitmaps containing coverage percentage for each
subpixel, instead of pixel
- Then draw by performing the blend for each subpixel, instead of pixel (e.g.
dual-source blending in opengl)
And there's only one Alpha channel, so this extra coverage data can't
leave Cairo to reach the compositor through there.
Therefore, it can't work as intended if output text alpha != bar background
alpha. Disable it for those cases, enable it elsewhere
As for color emojis, they are RGBA bitmaps. If drawn with text alpha=1.0
and background alpha=1.0 (should be completely opaque bar), then with
'CAIRO_OPERATOR_SOURCE' then texels with alpha < 1.0 result in a blend with
whatever's behind the bar, instead of the bar background
When swaybar receives the following JSON body
[
{
"full_text": "foo",
"separator": false,
"separator_block_width": 0
},
{
"full_text": "bar"
}
]
it should not draw any separator or any space between the two blocks.
However, since swaybar calculates that separator_block_width
0 is too small to fit any configured separator, it will override the
separator_block_width with some non-zero value. This patch changes
that such that the necessary separator_block_width is only expanded if
the block has 'separator: true'.
This should be in line to what i3 does, as its documentation of the
i3bar protocol for separator states that "[...] if you disable the
separator line, there will still be a gap after the block, unless you
also use separator_block_width".
See issue #5228. Currently, WL_OUTPUT_SUBPIXEL_NONE is ignored and
CAIRO_ANTIALIAS_SUBPIXEL is still set. This commit checks if subpixel is
set to none and if so, calls set_antialias with CAIRO_ANTIALIAS_GRAY.
This mirrors the functionality in Mako's
[PR261](https://github.com/emersion/mako/pull/261)
24e8ba048a did not take scaling into account.
The hotspot size used pixel coordinates, the absolute coordinates were logical,
and the relative coordinates were completely wrong.
This commit makes all coordinates use logical values. If
`"float_event_coords":true` is sent in the handshake message, coordinates are
sent as floating-point values.
The "scale" field is an integer containing the scale value.
This is the first in a series of commits to refactor the color handling
in sway. This changes parse_color to return whether it was success and
no longer uses 0xFFFFFFFF as the fallback color. This also verifies that
the string actually contains a valid hexadecimal number along with
the length checks.
In the process of altering the calls to parse_color, I also took the
opportunity to heavily refactor swaybar's ipc_parse_colors function.
This allowed for several lines of duplicated code to be removed.
Other components like workspace button, status line (error or plain
text) already render text at integer coords. This make status block
also render text at integer coords.
- Predicted status line can be negative, so corresponding variables should
not be unsigned. Changed to double as position is actually calculated as
double.
This commit mostly duplicates the wlr_log functions, although
with a sway_* prefix. (This is very similar to PR #2009.)
However, the logging function no longer needs to be replaceable,
so sway_log_init's second argument is used to set the exit
callback for sway_abort.
wlr_log_init is still invoked in sway/main.c
This commit makes it easier to remove the wlroots dependency for
the helper programs swaymsg, swaybg, swaybar, and swaynag.
Adds the bar subcommand `status_padding <padding>` which allows setting
the padding used for swaybar. If `status_padding` is set to `0`, blocks
will be able to take up the full height of the bar.
This modifies `bar_cmd_bindsym` to use `get_mouse_bindsym` for parsing
mouse buttons. This also introduces `cmd_bar_bindcode`, which will use
`get_mouse_bindcode` for parsing mouse buttons. Like sway bindings, the
two commands are encapsulated in a single file with shared code.
This also modifies swaybar to operate off of event codes rather than x11
button numbers, which allows for any mouse button to be used.
This introduces two new IPC properties:
- For `get_bar_config`, `event_code` has been added to the `bindings`
section and will include to event code for the button. If the event code
can be mapped to a x11 button, `input_code` will still be the x11 button
number. Otherwise, `input_code` will be `0`.
- Likewise for `click_events`, `event` has been added and will include
the event code for the button clicked. If the event code can be mapped
to a x11 button, `button` will still be the x11 button number.
Otherwise, `button` will be `0`.
This fixes the rendering of borders and backgrounds for blocks. This
also makes the following changes:
* both borders and padding are scaled with the output
* both lines and rectangles are rendered without an antialiasing to
avoid bleeding outside the desired area
When there are outputs with mixed scales, it was possible for swaybar to
alter `block->separator_block_width` for an output with a higher scale,
and use the changed value for a lower scale output. This caused there to
be larger than normal separation between blocks on the lower scale
outputs. The issue is more obvious the larger the scale difference
between the highest scale output and the lowest scale output.
This fixes the issue by using a local variable that is originally set to
`block->separator_block_width` for rendering, but if it needs to be
increased, the local variable is the only thing touched.
When `block->urgent` is set, use the urgent colors. This matches i3bar's
behavior. Previously, swaybar just ignored the property.
This also adds in rendering for right borders, which was missing.
Adds the bar subcommand `gaps <amount>|<horizontal> <vertical>|<top>
<right> <bottom> <left>` to set gaps for swaybar. Due to restrictions on
margins for a layer_surface, only the sides that are anchored to an edge
of the screen can have gaps. Since there is support for per-side outer
gaps for workspaces, those should be able to be used instead for the
last side.
Previously, when the bar was hidden, the height would be set to 0.
This meant that if the bar was empty upon reshow, it would not render
since the height was still 0, which made it seem there was a problem.
Now, the height is not reset, but the width is, to indicate upon reshow
that the layer surface needed reconfiguring.
As well as adding the hidden_state property to the bar config struct,
this commit handles barconfig_update events when the mode or
hidden_state changes, and uses a new function determine_bar_visibility
to hide or show the bar as required, using, respectively,
destroy_layer_surface, which is also newly added, and add_layer_surface,
which has been changed to allow dynamically adding the surface.
This distinguishes the binding mode from the distinct config mode, as
well as removing mode_pango_markup from the config struct where it
should not be present.
This was the source of numerous bugs, from hotplug events not being
received to segfaults because wl_display_roundtrip was making the
bar process unplug events while blocking in an iteration over all
outputs.
This now correctly handles an incoming json infinite array by shifting
most of the heavy listing to the json-c parser, as well as sending
multiple statuses at once. It also removes the struct
i3bar_protocol_state and moves its members into the status_line struct,
allowing the same buffer to be used for both protocols.
This prevents blocks from being destroyed before their hotspots are destroyed,
in case it is used for a pending click event that fires between the bar
receiving a new status, which destroys the block, and the bar rendering the new
status, which destroys the hotspot; this problem can be easily produced by
scrolling on a block that immediately causes a new status to be sent, with
multiple outputs
This does the following:
* Adds a baseline argument to get_text_size (the baseline is the
distance from the top of the texture to the baseline).
* Stores the baseline in the container when calculating the title
height.
* Takes the baseline into account when calculating the config's max font
height.
* When rendering, pads the textures according to the baseline so they
line up.
As well as ignoring scroll events on status elements when click_events
is enabled.
Previously, using the scroll wheel on a workspace button would switch to
that workspace instead of scrolling through them. Clicks and scrolling
on status elements would always be processed by swaybar, too. So in case
you were using scrolling as volume control on a status item, swaybar
would additionally scroll through your workspaces.
