Users can now define their own regex patterns, and use them via key
bindings:
[regex:foo]
regex=foo(bar)?
launch=path-to-script-or-application {match}
[key-bindings]
regex-launch=[foo] Control+Shift+q
regex-copy=[foo] Control+Mod1+Shift+q
That is, add a section called 'regex:', followed by an
identifier. Define a regex and a launcher command line.
Add a key-binding, regex-launch and/or regex-copy (similar to
show-urls-launch and show-urls-copy), and connect them to the regex
with the "[regex-name]" syntax (similar to how the pipe-* bindings
work).
This patch adds the following new search key bindings:
* extend-char (shift+right)
* extend-line-down (shift+down)
* extend-backward-char (shift+left)
* extend-backward-to-word-boundary (ctrl+shift+left)
* extend-backward-to-next-whitespace (ctrl+shift+alt+left)
* extend-line-up (shift+up)
They can be used to extend the search match (i.e. the selection).
This patch also adds an initial set of key bindings to scroll in the
scrollback history:
* scrollback-up-page
* scrollback-down-page
These work just like the key bindings for the normal mode. Also note
that it was already possible to scroll using the mouse.
This patch also fixes a couple of search mode bugs:
* crashing when a search match ends in the last column
* grapheme clusters not being matched correctly
* Search match not being "extendable" after a pointer leave event
* A few others, related to either large matches, or extending matches
after moving the viewport.
There are still a couple of (known) issues:
* A search match isn't correctly highlighted if its *starting* point
is outside the viewport.
* Extending the match to end of the scrollback (i.e. the most recent
output) is simply buggy.

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
Key-binding sets are bound to a seat/configuration pair. The conf
reference is done when a new terminal instance is created.
When that same terminal instance is destroyed, the key binding set is
unref:ed.
If the terminal instance is destroyed *before* the key binding set has
been referenced, we’ll still unref it. This creates an imbalance.
In particular, when the there is exactly one other terminal instance
referencing that same key binding set, that terminal instance will
trigger a foot server crash as soon as it receives a key press/release
event. This happens because the next-to-last terminal instance brought
the reference count of the binding set down to 0, causing it to be
free:d.
Thus, we *must* reference the binding set *before* we can error
out (when instantiating a new terminal instance).
At this point, we don’t yet have a valid terminal instance. But,
that’s ok, because all the key_binding_new_for_term() did with the
terminal instance was get the "struct wayland" and "struct config"
pointers. So, rename the function and simply pass these pointers
explicitly.
Similarly, change key_binding_for() to take a "struct config" pointer,
rather than a "struct terminal" pointer.
Also rename key_binding_unref_term() -> key_binding_unref().
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.
Closes#30
The global config doesn’t necessarily reflect the correct
configuration to use - we should *always* use the current terminal
instance’s conf pointer.
* Move selection override modifier mask to the key_binding_set struct
* Always warn if XDG activation is unavailable, not just if
bell.urgent is set (we no longer have access to this information)
* Pass ‘bool presentation_timings’ as a parameter to wayl_init()
* Remove ‘presentation_timings’ member from the ‘terminal’ struct
Closes#932
Up until now, our Wayland seats have been tracking key bindings. This
makes sense, since the seat’s keymap determines how the key bindings
are resolved.
However, tying bindings to the seat/keymap alone isn’t enough, since
we also depend on the current configuration (i.e. user settings) when
resolving a key binding.
This means configurations that doesn’t match the wayland object’s
configuration, currently don’t resolve key bindings correctly. This
applies to footclients where the user has overridden key bindings on
the command line (e.g. --override key-bindings.foo=bar).
Thus, to correctly resolve key bindings, each set of key bindings must
be tied *both* to a seat/keymap, *and* a configuration.
This patch introduces a key-binding manager, with an API to
add/remove/lookup, and load/unload keymaps from sets of key bindings.
In the API, sets are tied to a seat and terminal instance, since this
makes the most sense (we need to instantiate, or incref a set whenever
a new terminal instance is created). Internally, the set is tied to a
seat and the terminal’s configuration.
Sets are *added* when a new seat is added, and when a new terminal
instance is created. Since there can only be one instance of each
seat, sets are always removed when a seat is removed.
Terminals on the other hand can re-use the same configuration (and
typically do). Thus, sets ref-count the configuration. In other words,
when instantiating a new terminal, we may not have to instantiate a
new set of key bindings, but can often be incref:ed instead.
Whenever the keymap changes on a seat, all key bindings sets
associated with that seat reloads (re-resolves) their key bindings.
Closes#931
