When we’re using CSDs, we’ve up until now rendered a 5px invisible
border. This border handles interactive resizing. I.e. hovering it
changes the mouse cursor, and mouse button events are used to start an
interactive resize.
This patch makes it possible to color part of (or the entire) border,
with a configurable color.
To facilitate this, two new options have been added:
* csd.border-width
* csd.border-color
border-width defaults to 0, resulting in the look we’re used to.
border-color defaults to the title bar color. If the title bar color
hasn’t been set, it defaults to the default foreground color (just
like the title bar color does).
This means that, setting border-width but not border-color, results in
a border that blends with the title bar.
This changes the default value of tweak.grapheme-shaping to “yes”,
thus enabling grapheme shaping by default.
It also changes the default value of tweak.grapheme-width-method to
“wcswidth”, for maximum compatibility with terminal applications.
Using underlining for parameters allows the angle brackets to be
removed while still keeping a visual separation between literals
and parameters. The removes any uncertainty about whether the
angle brackets are part of the sequence or not. It also mirrors
the formatting used further down in the document.
foot doesn't show desktop notifications (via OSC777) if the current
terminal has keyboard focus.
This is probably a sane default, but there are use cases where showing
a notification regardless of the focus status may be desired. For
example, a completion notification of a long running task inside a
non-focused tmux window.
This PR adds the notify-focus-inhibit option which can be used to
disable inhibition of notifications when the window has focus.
The default value is `yes`, which retains the old behavior.
With dpi-aware=auto (the default), scale fonts using DPI *only*
if *all* available monitors have a scaling factor of one.
The idea is this: if a user, with multiple monitors, have enabled
scaling on *at least* one monitor, he/she has most likely done so to
match the size of his/hers other monitors.
For example, if the user has one monitor with a scaling factor of one,
and another one with a scaling factor of two, he/she expects things to
be twice as large on the second monitor.
If we (foot) scale using DPI on the first monitor, and using the
scaling factor on the second monitor, foot will *not* look twice as
big on the second monitor (this was the old behavior of
dpi-aware=auto).
Part of #714
Load a couple of ASCII glyphs and check if their advance widths
matches. If not, warn the user that the font is probably not
monospaced.
This can be disabled by setting tweak.font-monospace-warn=no.
Closes#704.
The meson command line option -Dcustom-terminfo-install-location has
been changed in the following ways:
* If unset, $datadir/terminfo is used, and TERMINFO is *not* exported
* If set, that value (relative to $prefix) is used, and TERMINFO *is*
exported.
* The special value ‘no’ is removed.
-Ddefault-terminfo now also changes the terminfo names generated when
-Dterminfo=enabled.
Furthermore, the documentation for the TERMINFO environment variable
has been removed from the foot.1 and footclient.1 man pages (but as
mentioned above, foot *will* still set it if
-Dcustom-terminfo-install-location has been used).
INSTALL.md has been updated to now recommend using ncurses’ terminfo
definitions, if available. But also to document the other
alternatives; installing the terminfo definitions in a custom
location, or installing them with a diferent name. It also describes
the general problem, and the disadvantages of each alternative (but
without going into too much depth).
As of 2021-07-31, ncurses ships its own version of foot’s terminfo.
Since:
* It doesn’t have the non-standard Sync,Tc,setrgbf,setrgbb
capabilities.
* It doesn’t set hs,fsl,dsl (statusbar).
* We want to be able to update our termminfo without waiting for an
ncurses release.
* Foot should be installable and usable on Linux systems that doesn’t
have the latest ncurses.
we still want to ship our own version. We can however not install it
to the default terminfo location (e.g. /usr/share/terminfo), since it
will collide with the ncurses provided files.
Our options are to either rename our terminfo to something else, or to
keep the name, but install our terminfo files somewhere else.
The first option would be the easy one. However, I think it makes
sense to use the same name. For example, a user that SSH’s into a
remote system that does *not* have our own version installed,
but *does* have the ncurses one, will gracefully fall back to that
one, which is better than manually having to set
e.g. TERM=xterm-256color.
Now, if we want to use the same name, we need to install it somewhere
else. But where? And how do we ensure our version is preferred over
the ncurses one?
I opted to $datadir/foot/terminfo (e.g. /usr/share/foot/terminfo) by
default. It makes it namespaced to foot (i.e. we’re not introducing a
new “standard” terminfo location), thus guaranteeing it wont collide
with ncurses.
To enable applications to find it, we export TERMINFO_DIRS. This is a
list of *additional* directories to search for terminfo files. If it’s
already defined, we *append* to it.
The nice thing with this is, if there’s no terminfo in that
location (e.g. when you SSH into a remote), the default terminfo
location is *also* searched. But only *after* having searched through
TERMINFO_DIRS.
In short: our version is preferred, but the ncurses one (or an older
version of our terminfo package!) will be used if ours cannot be
found.
To enable packagers full control over the new behavior, the existing
meson command line options have been modified, and a new option added:
-Dterminfo=disabled|enabled|auto: *build* and *install* the terminfo
files.
-Dcustom-terminfo-install-location=<path>: *where* the terminfo files
are expected to be found.
This *needs* to be set *even* if -Dterminfo=disabled. For example, if
the packaging script builds and packages the terminfo files separate
from the regular foot build. The path is *relative to $prefix*, and
defaults to $datadir/foot/terminfo.
This is the value that will be appended to TERMINFO_DIRS. Note that
you can set it to ‘no’, in which case foot will *not* set/modify
TERMINFO_DIRS. Only do this if you don’t intend to package foot’s
terminfo files at all (i.e. you plan on using the ncurses ones only).
-Ddefault-terminfo=foot. Allows overriding the default TERM
value. This should only be changed if the target platform doesn’t
support terminfo files.
Closes#671
This option specifies the characters allowed in the auto-detected
URLs.
Any character not in this set constitutes an URL delimiter, and will
never be included in auto-detected URLs.
This option does not affect OSC-8 URLs.
Closes#654
This patch adds a `confined` flag to each cell to track if the last
rendered glyph bled into it's right neighbor. To keep things simple,
bleeding into any other neighbor cell than the immediate right one is
not allowed. This should cover most use cases.
Before rendering a row we now do a prepass and mark all cells unclean
that are affected by a bleeding neighbor. If there are consecutive
bleeding cells, the whole group must be re-rendered even if only a
single cell has changed.
The patch also deprecates both old overflowing glyph options
*allow-overflowing-double-width-glyphs* and *pua-double-width* in favor
of a single new one named *overflowing-glyphs*.
This means that logging will be completely disabled until log_init()
has been called, which is useful to prevent log spam when running
UNITTEST{} blocks in debug builds.
Note that this doesn't change the default log level at runtime, which
was already being set to LOG_CLASS_INFO in main.c and client.c.
The new log level is also exposed to the command-line interface as
`--log-level=none`, which allows disabling logging entirely.
This option controls the foreground color of the
minimize/maximize/close buttons. I.e. the color used to draw the
minimize/maximize/close glyphs.
It defaults to default background color.
