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".
The following statusbar output is not considered by sway to be following
the swaybar-protocol:
{"version":1}[[{"full_text":"2.89","urgent":false}],
However this one is:
{"version":1}\n[[{"full_text":"2.89","urgent":false}],
Both outputs contain a header with the required values and an unfinished
array of objects with the required values, but the first one is showed
verbatim.
`determine_bar_visibility` stops and starts the status command process according to the bar’s visibility. If the bar was hidden during teardown, teardown would stall while waiting for the stopped status command process to exit.
This resumes a stopped status command during teardown and allows, for example, sway to reload or quit without leaving a swaybar instance behind each time.
Fixes#5536.
CONT before TERM as requested in review.
`$WAYLAND_SOCKET` is unset by `wl_display_connect` after it has
successfully connected to the wayland socket.
However, subprocesses spawned by swaybar (status-command) don't have
access to waybar's fds as $WAYLAND_SOCKET is O_CLOEXEC. This means any
status command which itself tries to connect to wayland will fail if
this environment variable is set.
Reorder display and status-command initialization so that this variable
is not set and add an assert so we can enforce this invariant in future.
For some reason my version of sway doesn't show workspace names:
$ swaymsg -t get_outputs
Output HDMI-A-1 '(null) (null) (null)' (inactive)
Output HDMI-A-2 '(null) (null) (null)' (inactive)
Which is weird, but it's no reason to crash swaybar. The field is
totally missing from the JSON, so it ends up doing strcmp(NULL, name)
which is undefined behavior.
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)
This removes any pending messages once the item is destroyed.
Furthermore, this installs SNI event calbacks asynchronously
in order to prevent sd-bus from bypassing pending messages.
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.
The function group_handler may get a nullptr as `new_group`. If that's
the case, return true, as if `new_group` was the empty string.
Also make the conversion to bool explicit when calling `strcmp`.
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.
In case a tray icon cannot be found or does not have a desirable size,
swaybar retries the search again and again, which increases load on disk
and CPU. This commit solves it by storing target_size for each icon, so
that swaybar does not search for an icon of some size if it already tried to.
Fixes#3789.
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.
This adds complete support for the barconfig_update ipc event. This also
changes the bar command and subcommand handlers to correctly emit the
event. This makes it so all bar subcommands other than id and
swaybar_command are dynamically changeable at runtime. sway-bar.5 has
been updated accordingly
This corrects the description of border_{top,bottom,left,right} in the
block properties table in swaybar-protocol.7. The values should be an
integer denoting the width/height rather than a boolean denoting
whether to show them.
Note: since strtoul() has no real error return code (both 0 and
ULONG_MAX may be returned on both success and failure), set errno=0
before calling strtoul().
If the XCURSOR_THEME and/or XCURSOR_SIZE environment variables are
set, use the theme and size they define.
If they're not set, use the same defaults as before (system default
theme, size=24).
This allows swaybar to become visible when the mode changes (to any
mode other than the default). swaybar will be hidden again when the
modifier is pressed and released or when switching back to the default
mode.
This also applies the same logic to visible by urgency to hide swaybar
when the modifier is pressed and released.
These changes are to match i3's behavior.
The read_theme_file function used to return an invalid icon_struct in
some cases, for example when an empty index.theme file was read.
This makes sure the struct we're returning is always valid as per the
Icon Theme specification.

- Predicted status line can be negative, so corresponding variables should
not be unsigned. Changed to double as position is actually calculated as
double.
If the icon index.theme contained a key-value pair without a preceding
group header, entry_handler() would be called with a zero pointer and
lead to a segfault.
Set the error flag and break on such malformed files.
`len` will underflow but will overflow right after, so it's not as bad as it
may appear. Still better not to under/overflow at all.
