Release 1.4.0
Added
-----
* `Sync` to terminfo. This is a tmux extension that indicates
_"Synchronized Updates"_ are supported.
* `--hold` command line option to `footclient`.
* Key mapping for `KP_Decimal`.
* Terminfo entries for keypad keys: `ka1`, `ka2`, `ka3`, `kb1`, `kb3`,
`kc1`, `kc2`, `kc3`, `kp5`, `kpADD`, `kpCMA`, `kpDIV`, `kpDOT`,
`kpMUL`, `kpSUB` and `kpZRO`.
* **blink** option to `footrc`; a boolean that lets you control
whether the cursor should blink or not by default. Note that
applications can override this.
* Multi-seat support
* Implemented `C0::FF` (form feed)
* **pipe-visible** and **pipe-scrollback** key bindings. These let you
pipe either the currently visible text, or the entire scrollback to
external tools (https://codeberg.org/dnkl/foot/issues/29). Example:
`pipe-visible=[sh -c "xurls | bemenu | xargs -r firefox] Control+Print`
Changed
-------
* Background transparency to only be used with the default background
color.
* Copy-to-clipboard/primary-selection to insert a line break if either
the last cell on the previous line or the first cell on the next
line is empty.
* Number of lines to scroll is now always clamped to the number of
lines in the scrolling region..
* New terminal windows spawned with `ctrl`+`shift`+`n` are no longer
double forked.
* Unicode combining character overflow errors are only logged when
debug logging has been enabled.
* OSC 4 (_Set Color_) now updates already rendered cells, excluding
scrollback.
* Mouse cursor from `hand2` to `left_ptr` when client is capturing the
mouse.
* Sixel images are now removed when the font size is **decreased**.
* `DECSCUSR` (_Set Cursor Style_, `CSI Ps SP q`) now uses `Ps=0`
instead of `Ps=2` to reset the style to the user configured default
style. `Ps=2` now always configures a _Steady Block_ cursor.
* `Se` terminfo capability from `\E[2 q` to `\E[ q`.
* Hollow cursor to be drawn when window has lost _keyboard_ focus
rather than _visual_ focus.
Fixed
-----
* Do not stop an ongoing selection when `shift` is released. When the
client application is capturing the mouse, one must hold down
`shift` to start a selection. This selection is now finalized only
when the mouse button is released - not as soon as `shift` is
released.
* Selected cells did not appear selected if programmatically modified.
* Rare crash when scrolling and the new viewport ended up **exactly**
on the wrap around.
* Selection handling when viewport wrapped around.
* Restore signal mask in the client process.
* Set `IUTF8`.
* Selection of double-width characters. It is no longer possible to
select half of a double-width character.
* Draw hollow block cursor on top of character.
* Set an initial `TIOCSWINSZ`. This ensures clients never read a
`0x0` terminal size (https://codeberg.org/dnkl/foot/issues/20).
* Glyphs overflowing into surrounding cells
(https://codeberg.org/dnkl/foot/issues/21).
* Crash when last rendered cursor cell had scrolled off screen and
`\E[J3` was executed.
* Assert (debug builds) when an `\e]4` OSC escape was not followed by
a `;`.
* Window title always being set to "foot" on reset.
* Terminfo entry `kb2` (center keypad key); it is now set to `\EOu`
(which is what foot emits) instead of the incorrect value `\EOE`.
* Palette re-use in sixel images. Previously, the palette was reset
after each image.
* Do not auto-resize a sixel image for which the cllent has specified
a size. This fixes an issue where an image would incorrectly
overflow into the cell row beneath.
* Text printed, or other sixel images drawn, on top of a sixel image
no longer erases the entire image, only the part(s) covered by the
new text or image.
* Sixel images being erased when printing text next to them.
* Sixel handling when resizing window.
* Sixel handling when scrollback wraps around.
* Foot now issues much fewer `wl_surface_damage_buffer()` calls
(https://codeberg.org/dnkl/foot/issues/35).
* `C0::VT` to be processed as `C0::LF`. Previously, `C0::VT` would
only move the cursor down, but never scroll.
* `C0::HT` (_Horizontal Tab_, or `\t`) no longer clears `LCF` (_Last
Column Flag_).
* `C0::LF` now always clears `LCF`. Previously, it only cleared it
when the cursor was **not** at the bottom of the scrolling region.
* `IND` and `RI` now clears `LCF`.
* `DECAWM` now clears `LCF`.
* A multi-column character that does not fit on the current line is
now printed on the next line, instead of only printing half the
character.
* Font size can no longer be reduced to negative values
(https://codeberg.org/dnkl/foot/issues/38).
