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.
Doing so will schedule the renderer “as soon as possible”. I.e we’re
by-passing the regular scheduler, and thus we’re by-passing the user’s
setting of the delayed-render-* timers.
The fact that we’re scheduling “as soon as possible” also means we’re
much more likely to trigger flickering, or color flashes, if the
application is changing colors which are on the screen.
To handle changes to the cursor color(s), use the new
term_damage_cursor() instead of render_refresh().
To handle background color changes, which affect the margins, use the
new term_damage_margins() instead of render_refresh_margins(),
Closes#141
term_damage_cursor() damages the cell where the cursor is currently
at. This can be used to ensure the cursor is re-drawn, if there aren’t
any other pending updates.
term_damage_margins() requests the margins be redrawn the next time we
render the grid.
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
An odd cell width/height sometimes resulted in an odd grid
size. Combined with a scaling factor of e.g. 2, that led to a rounding
error when converting pixel sizes to logical window sizes.
As a result, the _next_ configure event would cause us to loose a
pixel, which led to us dropping a row from the grid.
The keycodes will change if the seat’s keymap changes. Make sure we
only do alternate scrolling if the seat has a keyboard, and use
the *current* layout’s keycodes for arrow up/down (instead of
the *first* layout’s).
