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
Virtual machine monitor programs (e.g. QEMU, Cloud Hypervisor) expose
guest consoles as PTYs. With this patch, foot can access these guest
consoles.
Usually, the program used for accessing these PTYs is screen, but
screen is barely developed, doesn't support resizing, and has a bunch
of other unrelated stuff going on. It would be nice to have a
terminal emulator that properly supported opening an existing PTY.
The VMM controls the master end of the PTY, so to the other end (in
this case foot), it just behaves like any application running in a
directly-opened PTY, and all that's needed is to change foot's code to
support opening an existing PTY rather than creating one.

This adds support for a new OSC escape sequence: OSC 176, that lets
terminal programs tell the terminal the name of the app that is
running. foot then sets the app ID of the toplevel to that ID,
which lets the compositor know which app is running, and typically
sets the appropriate icon, window grouping, ...

When launching footclient with -E,--client-environment the environment
variables that should be set by foot, wasn't.
Those variables are:
* TERM
* COLORTERM
* PWD
* SHELL
and all variables defined by the user in the [environment] section in
foot.ini.
In the same way, we did not *unset* TERM_PROGRAM and
TERM_PROGRAM_VERSION.
This patch fixes it by "cloning" the custom environment, making it
mutable, and then adding/removing the variables above from it.
Instead of calling setenv()/unsetenv() directly, we add the wrapper
functions add_to_env() and del_from_env().
When *not* using a custom environment, they simply call
setenv()/unsetenv().
When we *are* using a custom environment, add_to_env() first loops all
existing variables, looking for a match. If a match is found, it's
updated with the new value. If it's not found, a new entry is added.
del_from_env() loops all entries, and removes it when a match is
found. If no match is found, nothing is done.
The mutable environment is allocated on the heap, but never free:d. We
don't need to free it, since it's only allocated after forking, in the
child process.
Closes#1568
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
Even if WAYLAND_DISPLAY / XDG_RUNTIME_DIR are defined, if we can't
find the corresponding socket, we fallback to the path used when they
are not defined.
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
Foot’s policy is to not set environment variables that identifies
it (except the well-known and established `TERM` variable).
We encourage applications to use terminfo to determine capabilities,
or terminal queries, when available. Or, at least use terminal queries
to detect the terminal and its version.
Setting environment variables is a bad idea since they are inherited
by all applications started by the terminal (which is the whole
point). But, this includes other terminal emulators, making it very
possible a terminal emulator gets mis-detected just because it was
started from another terminal.
Since there are a couple of terminal emulators that _do_ set
TERM_PROGRAM and TERM_PROGRAM_VERSION, unset these environment
variables to avoid being misdetected.
Closes#1349
