If the value is specified without a unit, then the value is assumed to
be in points, subject to DPI scaling.
The value can optionally have a ‘px’ suffix, in which case the value
is treated as a raw pixel count.
0, the default, means no additional spacing; the cell width is defined
by the font metrics.
A positive value *adds* to the width from the font metrics, while a
negative value *subtracts*.
When set, the grid contents is centered in the window. I.e. the
left/right and top/bottom margins are equal (+- 1px).
This causes the content to “jump” while doing an interactive resize,
but may still be preferred in e.g. a tiling WM.
Closes#273
We don’t write anything more to the buffer after this, but this makes
this code consistent with all other code that pushes new data to the
buffer.
This makes it easier to search, and validate, the
ensure_size()+push-data pattern.
‘idx’ is where _new_ data should be pushed into the buffer. Thus it is
perfectly valid for it to be equal to ‘size’ - it just means we need
to allocate more space before pushing data to it.
This fixes an assertion triggered when selecting the upper left cell
and dragging down.
We would end up trying to decrement the pivot end point, hitting an
assertion that only is valid while skipping spacers.
Remove the assertion, and allow pivot points to be moved across line
wraps, but take care not to move outside the visible screen area.
If the initial character is a space, find the next non-space
character.
If the initial character is a delimiter, find the next non-delimiter
character (space, or word character).
If the initial character is neither (i.e, it is a word character),
find the next non-word character.
Extend selection pivoting to allow selections to pivot around a
range.
Use this in word- and row-based selections to pivot around the initial
word/row that was selected.
This mimics the behavior of at least urxvt and xterm.
This removes the selection_mark_word() and selection_mark_row()
functions. To start a word/row-based selection, use selection_start()
with SELECTION_SEMANTIC_{WORD,ROW}
