When a sixel image crosses the scrollback wrap-around, it is split up
into (at least) two pieces.
We use cursor->point.col for all pieces’ x-coordinate. This caused the
final image to appear sheared, since we do a carriage-return (after a
number of linefeeds) after each piece - this causes the cursor’s
position to be reset to the left margin.
The solution is simple; remember the cursor’s initial x-coordinate,
and use that to position all image pieces.
Closes#151.
This fixes a crash when the emitted sixel extends beyond the right
margin. The crash only happens when there are other sixel images
already emitted.
Fixes part of #151
When we detected an invalid section name, we correctly logged this and
warned the user.
However, the internal state machine now had an invalid section enum
value. This caused a crash when the next key/value pair was to be
parsed and we tried to lookup which parser function to call.
Closes#159.
Trackpad scroll movements are in pixels. Foot previously “translated”
these directly to line movements (i.e. a one pixel scroll event was
translated into a one line scroll).
Now we use the line height of the terminal and correctly convert
pixels to lines.
This makes the trackpad scroll speed in foot consistent with the
scroll speed in e.g. Alacritty and Kitty.
Allow a mouse binding to match even if its click count is less than
the actual click count.
If there are multiple bindings that match, use the one with the
highest click count (that less than, or equal to the actual click
count).
Closes#146
Use the new fcft_set_scaling_filter() API to use a non-default scaling
filter.
By default, we use lanczo3, the ‘best’ filter. This overrides the
default in fcft, which is ‘cubic’ filtering.
This deprecates/renames scrollback-up/down to scrollback-up/down-page.
It also renames scrollback-up/down-half to
scrollback-up/down-half-page, and adds the new bindings
scrollback-up/down-line.
Even though we translate the cursor position from the old grid
coordinates to the new, the cursor may _still_ end up outside the
visible area.
Make sure it doesn’t.
The deprecation sections mentions ‘footrc’ being deprecated, and
replaced by ‘foot.ini’. Since a lot of the changelog entries refer to
foot.ini, make sure the user sees this first.
Also, use foot.ini (and not footrc) consistently in all changelog entries.
Try to detect double-width *glyphs* for single-width *characters*, and
allow them to overflow into the next cell.
This is only done for single-width chars with a glyph width that is at
least 1.5 cells wide, but at most 3 cells.
The feature is gated by the new
‘tweak.allow-overflowing-double-width-glyphs’, and is disabled by
default.
Closes#116
When calculating where in the scrollback history we are, we previously
did this against the total number of scrollback lines. I.e. the
`scrollback.lines` setting in `footrc`.
Now, we count only the used/allocated scrollback lines.
Note that the initial indicator position might still seem to start a
bit high up, if the number of used scrollback lines is low. This is
because we use the *top* of the screen for the current position. Thus,
we'll never be at the bottom (except for the special case when
we're *really* at the bottom).
This is also done by libvte, alacritty, kitty and several other
terminal emulators as a way to indicate support for 24-bit RGB
colors. It generally also implies support for the xterm 256-color
palette and basic ECMA-48 colors.
This introduces a new state to a seat's mouse struct, 'consumed'. It
is set on a mouse *press* event that is claimed by a mouse binding.
It is cleared after a mouse *release* event.
While set, *no* mouse motion or button events are sent to the client
application.
We only updated the grid for OSC 4 - Set color <idx>. But we did *not*
do it for 104 (reset color <idx>), 10 - set default foreground, 11 -
set default background, 110 - reset default foreground, or 111 - reset
default background.
