We have no guarantee that sub-surfaces extending outside the window
geometry are rendered correctly (if at all).
For example, both Sway and River will render the window border on top
of the sub-surface.
Future versions of Sway may clip the sub-surface.
Since jump-labels are positioned slightly above, and to the left of
the URLs first character, having a label on either the top row, or on
the first column, will likely position it outside the window. This is
handled by simply setting x/y to 0 (or, to -margin, since the label
coordinate is later offsetted with the window margins).
Second, if the label is very long, it may extend outside the
window. This is very unusual for labels only showing the key, and not
the URL itself, but could happen in this case too, if e.g. the user
has configured double-width key characters.
This is handled by calculating its maximum width, and then truncating
the label.
Although very unlikely, it is possible for a label to also extend
outside the window’s vertical size. This could happen for very small
font sizes, where the label’s own margins are large, relative to the
font size. This case is currently not handled.
Closes#443
When disabled, we render box drawing characters ourselves. This is the
default.
When enabled, we instead use font glyphs. I.e. no special treatment.
Closes#430
Foot currently does reverse-wrapping (‘auto_left_margin’, or ’bw’) on
everything that calls ‘term_cursor_left()’. This is wrong; it should
only be done for cub1. From man terminfo:
auto_left_margin | bw | bw | cub1 wraps from column 0 to last
column
This patch moves the reverse-wrapping logic from term_cursor_left() to
the handling of BS (backspace).
Closes#441
This is done by:
* Not limiting the number of times we try to read from the PTY when
we’ve have POLLHUP
* Not requiring the entire the previous read to have filled our
buffer.
* Not erroring out on EIO.
Defensive programming; output_geometry() etc are typically only called
once for an output instance. But let’s ensure we’re not leaking memory
if it’s called more than once.
This ensures we don’t accidentally reference them from places we
shouldn’t.
Unfortunately, binding_action_map[] (for “normal” key bindings) cannot
easily be made function local since it is used when parsing both key-
and mouse bindings (i.e. it’s used in multiple functions).
Don’t call has_key_binding_collisions() with ‘binding_action_map’
unconditionally; use the provided ‘action_map’ instead.
This fixes wrong error messages for key combo collisions in key
binding sections other than the regular “key-bindings”.
sixel_color_set() is called when the number of (sixel) color registers
is changed.
It frees the current palette, and changes the “palette size” variable.
Originally, we only had a single palette. This is the one free:d by
sixel_color_set().
Later, we added support for private vs. shared palettes. With this
change, we now have one palette that is “never” free:d (the shared
one), and a private palette that is always free:d after a sixel has
been emitted.
‘sixel.palette’ is a pointer to the palette currently in use, and
should only be accessed **while emitting a sixel**.
This is the pointer sixel_color_set() free:d. So for example, if
‘sixel.palette’ pointed to the shared palette, we’d free the shared
palette. But, we didn’t reset ‘sixel.shared_palette’, causing a double
free later on.
Closes#427
There were two issues with it:
* Not all applications decode the sequence into a set of modifiers +
key, but use a fixed sequence -> combo mapping, that we broke.
* There were unforeseen issues with e.g. F1-12, where the modifier
were removed from combos like Ctrl+F12, or Alt+F12. The reason is
simple; XKB tells us that Ctrl, or Alt, is a consumed modifier. Now,
_why_ it thinks that is a different story.

While we don’t (yet) have any unit tests for foot, users can build
foot with e.g. fcft and/or tllist as sub-projects. *They* have tests,
and when doing PGO builds, those test binaries *must* be executed, or
we get link failures in the final build.
