If output_cmd_background is given a valid mode as the first argument,
then there is no file given and an error should be returned.
join_args should not be called with an argc of zero since it sets the
last character to the null terminator. With an argc of zero, the length
is zero causing a heap buffer overflow when setting the byte before the
start of argv to '\0'. This probably will not ever generate a segfault,
but may cause data corruption to whatever is directly before it in
memory. To make other such cases easier to detect, this also adds a
sway_assert in join_args when argc is zero.
Modifier handling functions were moved into sway/input/keyboard.c;
opposite_direction for enum wlr_direction into sway/tree/output.c;
and get_parent_pid into sway/tree/root.c .
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.
Previously, the success of `getline` was tested by checking if the
buffer it allocates is nonempty and has a nonzero first byte. As
`getline` does not explicitly zero out its memory buffer, this may
fail (e.g., with AddressSanitizer). Instead, we check that at least one
character was returned on standard output.
Also, trailing newlines (if present) are now removed.
There's no point having both movement_direction and wlr_direction. This
replaces the former with the latter.
As movement_direction also contained MOVE_PARENT and MOVE_CHILD items,
these are now checked specifically in the focus command and handled in
separate functions, just like the other focus variants.
* The loop functions are now prefixed with `loop_`.
* It is now easy to add timers to the loop.
* Timers are implemented using pollfd and timerfd, rather than manually
checking them when any other event happens to arrive.
render_background_image alters the scale that cairo uses. Depending on
the image mode, resolution, and image size, this may cause the surface
to be rendered increasingly smaller. By calling cairo_save and
cairo_restore, any changes to the cairo settings by the function are
not kept as a side effect.
The surface that swaybg uses is also now cleared before rendering a frame.
This is needed to avoid artifacts on resolution or scale changes with
certain combinations of image modes, resolutions, and image sizes. This
was also part of the increasingly smaller background visual since it
made it so it was not obvious the region being rendered to was smaller
and caused an increasing number of smaller images to be appear for each
hotplug.
Call pango_cairo_context_set_font_options() before pango_cairo_update_layout() and pango_cairo_show_layout(). By default, Pango "merges" the Cario font options with its own, which doesn't enable full hinting.
Fixes#2674.
The cause of the issue was in get_pango_layout. When we call
pango_parse_markup, `text` is the escaped string, and the unescaped
string is then computed and written to `buf`. We were then passing the
unescaped string to pango_layout_set_markup, but this function needs the
escaped string. `buf` is not needed and has been removed.
The other part of this PR refactors escape_markup_text to remove the
dest_length argument and removes the -1 return value on error. It now
assumes that you've allocated dest to the correct length.
This now uses the getline function to receive the header, replacing
read_line_buffer, which has been deleted since it is otherwise unused.
Furthermore, once the protocol has been determined, the current status
is handled immediately to be shown (though this has not been added for
the i3bar protocol since it has not yet been rewritten to handle this).
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.
