BTN_BACK and BTN_FORWARD are separate buttons. The scroll wheel don't
have any button mappings in libinput/wayland, so make up our own
defines.
This allows us to map them in mouse bindings.
Also expose BTN_WHEEL_{LEFT,RIGHT}. These were already defined, and
used, internally, to handle wheel tilt events. With this, they can
also be used in mouse bindings.
Finally, fix encoding used for BTN_{BACK,FORWARD} when sending mouse
button events to the client application. Before this, they were mapped
to buttons 4/5. But, button 4/5 are for the scroll wheel, and as
mentioned above, BTN_{BACK,FORWARD} are not the same as scroll wheel
"buttons".
Closes#1763
This option controls how we render the cursor when the terminal window
is unfocused.
Possible values are:
* hollow: the default, and how we rendered the cursor before this
patch.
* unchanged: render the cursor exactly the same way as when the window
is focused.
* none: do not render any cursor at all
Closes#1582
This implements private mode 2027 - grapheme cluster processing, as
defined in the "Terminal Unicode Core"[1] specification.
Internally, we just flip the already existing option "grapheme
shaping". Since it's now runtime changeable, we need a copy of it in
the terminal struct, rather than referencing the conf object.

This patch changes the default of triple clicking, from selecting the
current logical row, to first trying to select the contents of the
quote under the cursor, and if failing to find a quote, selecting the
current row (like before).
This is implemented by adding a new key binding, 'select-quote'.
It will search for surrounding quote characters, and if one is found
on each side of the cursor, the quote is selected. If not, the entire
row is selected instead.
Subsequent selection operations will behave as if the selection is
either a word selection (a quote was found), or a row selection (no
quote found).
Escaped quote characters are not supported: "foo \" bar" will match
'foo \', and not 'foo " bar'.
Mismatched quotes are not custom handled. They will simply not match.
Nested quotes ("123 'abc def' 456") are supported.
Closes#1364
Un-grabbed wheel events are now passed through the mouse binding
matching logic, instead of being hardcoded to scrolling the terminal
contents.
They are mappable through the BTN_BACK and BTN_FORWARD buttons.
Since they're not actually button *presses*, they never generate a
click count other than 1. This limitation is documented, but not
checked in the config. This means it's possible to create bindings
like "BTN_BACK+3" (i.e. triple "click"). They will however never
trigger.
The old, hardcoded logic is now accessible through the new
scrollback-up-mouse and scrollback-down-mouse mouse
bindings. They (obiously) default to BTN_BACK and BTN_FORWARD,
respectively.
Example usage: keep the default of scrolling terminal contents with
the wheel, when used without modifiers, but map Control+wheel to font
zoom in/out:
[mouse-bindings]
font-increase=Control+BTN_FORWARD
font-decrease=Control+BTN_BACK
(this also keeps the default key bindings to zoom in/out; ctrl-+ and
ctrl+-)
Closes#1077
By how much to increase the luminance when brightening bold
fonts. This was previously hard-coded to a factor of 1.3, which is now
the default value of the new config option.
Closes#1434
When enabled, double-clicking the CSD titlebar will (un)maximize the
window.
Defaults to ‘yes’ (since this is the old hard-coded behavior).
Closes#1293
Having a keybinding to invoke arbitrary unicode characters is very
useful. It's often used as a method of last resort to communicate with
people outside of your main language. For example, if you want to type
the last letter of my real name, you can invoke the latin-1 character
0xe9 or unicode 0x00e9.
You can also use this to type special characters, for example, unicode
U+1F4A9 is of course, the infamous PILE OF POO, which is sure to
produce million laughs everywhere you go.
In foot, there's no keybinding by default to invoke the very useful
unicode-input command. There is no "standard" (as in "ISO") keybinding
this either. But there *is* a de-facto standard currently deployed
by *both* GTK and Qt (a rare feat) *and* Chrome OS (an even rarer
feat) and it's control-shift-u.
Alternatives include Control-x 8 (emacs), Control V u (vim),
Alt (Windows, LibreOffice), or Option (Mac). I doubt we want to adopt
any of those.
So let's use control-shift-u for this. Unfortunately, it's currently
assigned to show-urls-launch, which is unfortunate, but
insurmountable. We can reassign this keybinding elsewhere. I have
picked control-shift-o in my configuration, because "o" is a good
mnemonic for "open URLs". Others have suggested "m" instead.
Closes: #1183
We now default to scaling fonts using the scaling factor, not monitor
DPI.
The ‘auto’ value for dpi-aware has been removed.
Documentation (man pages and README) have been updated to reflect the
new default.
For this to work, the default app-id of footclient has been changed
from ‘foot’ to ‘footclient’.
By using distinct StartupWMClasses, the compositor can connect a
running foot/footclient instance to the correct .desktop-file. This
ensures the correct icon is being used in e.g. docks, and that actions
like “open another window” works correctly.
Note that the user can override the app-id, either by setting app-id
in foot.ini, or with the -a,--app-id command line option.
Closes#1355
This patch generalizes the utmp support, to not only support
libutempter, but also ulog (and in the future, even more interfaces).
* Rename config option main.utempter to main.utmp-helper
* Add meson option -Dutmp-backend=none|libutempter|ulog|auto
* Rename meson option -Ddefault-utempter-path to -Dutmp-default-helper-path
* utmp is no longer detected at compile time, but at runtime instead.
Meson will configure the following pre-processor macros, based on the
selected utmp backend:
* UTMP_ADD - argument to pass to utmp helper when adding a record (starting foot)
* UTMP_DEL - argument to pass to utmp helper when removing a record (exiting foot)
* UTMP_DEL_HAVE_ARGUMENT - if defined, UTMP_DEL expects an extra argument ($WAYLAND_DISPLAY)
* UTMP_DEFAULT_HELPER_PATH - path to the default utmp helper binary
The documentation has been updated to mention which arguments are
passed to the helper binary.
Closes#1314
The old default, wcswidth, simply calls wcswidth() on the grapheme
cluster. This was supposedly the implementation with the highest
application compatibility. Except we never even tried to measure
it. It was just assumed.
A lot of modern applications have better implementations. Let’s try to
push support for better emoji support by changing our default method
from wcswith to double-width.
While far from correct (it’s not based on the Unicode tables), the
‘double-width’ method produces accurate results anyway.
double-width is like wcswidth(), in that it adds together the
individual wcwidths of all codepoints in the grapheme cluster. But, it
limits the maximum width to 2.
This patch adds a new config option, font-size-adjustment.
It lets you configure how much the font size should be
incremented/decremented when zooming in or out (ctrl-+, ctrl+-).
Values can be specified in points, pixels or percent.
Closes#1188
Reflowing a large scrollback is *slow*. During an interactive resize,
it can easily take long enough that the compositor fills the Wayland
socket with configure events. Eventually, the socket becomes full and
the compositor terminates the connection, causing foot to exit.
This patch is work-in-progress, and the first step towards alleviating
this.
It delays the reflow by:
* Snapshotting (copying) the original grid when an interactive resize
is started.
* While resizing, we apply a simple truncation resize of the
grid (like we handle the alt screen).
* When the resize is done, or paused for ‘resize-delay-ms’, the grid
is reflowed.
TODO: we *must* not allow any changes to the temporary (truncated)
grid during the resize. Any changes to the grid would be lost when the
final reflow is applied. That is, we must completely pause the ptmx
pipe while a resize is in progress.
Future improvements:
The initial copy can be slow. We should be able to avoid it by
rewriting the reflow algorithm to not free anything. This is
complicated by the fact that some resources (e.g. sixel images) are
currently *moved* to the new grid. They’d instead have to be copied.
This patch adds support for creating utmp records using the ‘utempter’
helper binary from the ‘libutempter’ package.
* New config option ‘main.utempter’
* New meson command line option, -Ddefault-utempter-path. Defaults to
auto-detecting the path.
The default value of the new ‘main.utempter’ config option depends on
the meson command line option ‘-Ddefault-utempter-path’.
If ‘main.utempter’ is *not* set to ‘none’, foot will try to execute
the utempter helper binary to create utmp records when a new terminal
is instantiated. The record is removed when the terminal instance is
destroyed.
This is my variant of the solarized theme, were only the first eight
colors (i.e. the "normal") colors are from the solarized theme. The
remaining eight (the "bright" colors) are brightened versions of the
"normal" colors. This results in a theme that is usually in all
applications, not just those that are "aware" that the terminal color
theme is "solarized".
This adds an "underline-thickness" setting to the "main" section,
similar to the existing "underline-offset" setting. This setting is used
to specify a custom height for regular (= non-cursor) underlines.
Fixes#1136
This mode is activated through the new key-bindings.unicode-input and
search-bindings.unicode-input key bindings.
When active, the user can “build” a Unicode codepoint by typing its
hexadecimal value.
Note that there’s no visual feedback in this mode. This is
intentional. This mode is intended to be a fallback for users that
don’t use an IME.
Closes#1116
This patch adds support for the OSC-133;A sequence, introduced by
FinalTerm and implemented by iTerm2, Kitty and more. See
https://iterm2.com/documentation-one-page.html#documentation-escape-codes.html.
The shell emits the OSC just before printing the prompt. This lets the
terminal know where, in the scrollback, there are prompts.
We implement this using a simple boolean in the row struct ("this row
has a prompt"). The prompt marker must be reflowed along with the text
on window resizes.
In an ideal world, erasing, or overwriting the cell where the OSC was
emitted, would remove the prompt mark. Since we don't store this
information in the cell struct, we can't do that. The best we can do
is reset it in erase_line(). This works well enough in the "normal"
screen, when used with a "normal" shell. It doesn't really work in
fullscreen apps, on the alt screen. But that doesn't matter since we
don't support jumping between prompts on the alt screen anyway.
To be able to jump between prompts, two new key bindings have been
added: prompt-prev and prompt-next, bound to ctrl+shift+z and
ctrl+shift+x respectively.
prompt-prev will jump to the previous, not currently visible, prompt,
by moving the viewport, ensuring the prompt is at the top of the
screen.
prompt-next jumps to the next prompt, visible or not. Again, by moving
the viewport to ensure the prompt is at the top of the screen. If
we're at the bottom of the scrollback, the viewport is instead moved
as far down as possible.
