# Foot Code of Conduct
|
||||||
|
|
||||||
|
## Our Pledge
|
||||||
|
|
||||||
|
We as members, contributors, and leaders pledge to make participation in our
|
||||||
|
community a harassment-free experience for everyone, regardless of age, body
|
||||||
|
size, visible or invisible disability, ethnicity, sex characteristics, gender
|
||||||
|
identity and expression, level of experience, education, socio-economic status,
|
||||||
|
nationality, personal appearance, race, caste, color, religion, or sexual
|
||||||
|
identity and orientation.
|
||||||
|
|
||||||
|
We pledge to act and interact in ways that contribute to an open, welcoming,
|
||||||
|
diverse, inclusive, and healthy community.
|
||||||
|
|
||||||
|
## Our Standards
|
||||||
|
|
||||||
|
Examples of behavior that contributes to a positive environment for our
|
||||||
|
community include:
|
||||||
|
|
||||||
|
* Demonstrating empathy and kindness toward other people
|
||||||
|
* Being respectful of differing opinions, viewpoints, and experiences
|
||||||
|
* Giving and gracefully accepting constructive feedback
|
||||||
|
* Accepting responsibility and apologizing to those affected by our mistakes,
|
||||||
|
and learning from the experience
|
||||||
|
* Focusing on what is best not just for us as individuals, but for the overall
|
||||||
|
community
|
||||||
|
|
||||||
|
Examples of unacceptable behavior include:
|
||||||
|
|
||||||
|
* The use of sexualized language or imagery, and sexual attention or advances of
|
||||||
|
any kind
|
||||||
|
* Trolling, insulting or derogatory comments, and personal or political attacks
|
||||||
|
* Public or private harassment
|
||||||
|
* Publishing others' private information, such as a physical or email address,
|
||||||
|
without their explicit permission
|
||||||
|
* Other conduct which could reasonably be considered inappropriate in a
|
||||||
|
professional setting
|
||||||
|
|
||||||
|
## Enforcement Responsibilities
|
||||||
|
|
||||||
|
Community leaders are responsible for clarifying and enforcing our standards of
|
||||||
|
acceptable behavior and will take appropriate and fair corrective action in
|
||||||
|
response to any behavior that they deem inappropriate, threatening, offensive,
|
||||||
|
or harmful.
|
||||||
|
|
||||||
|
Community leaders have the right and responsibility to remove, edit, or reject
|
||||||
|
comments, commits, code, wiki edits, issues, and other contributions that are
|
||||||
|
not aligned to this Code of Conduct, and will communicate reasons for moderation
|
||||||
|
decisions when appropriate.
|
||||||
|
|
||||||
|
## Scope
|
||||||
|
|
||||||
|
Participants in the foot community are expected to uphold the described
|
||||||
|
standards not only in official community spaces (issue trackers, IRC channels,
|
||||||
|
etc.) but in all public spaces. The Code of Conduct however does acknowledge
|
||||||
|
that people are fallible and that it is possible to truly correct a past
|
||||||
|
pattern of unacceptable behavior. That is to say, the scope of the Code of
|
||||||
|
Conduct does not necessarily extend into the distant past.
|
||||||
|
|
||||||
|
## Enforcement
|
||||||
|
|
||||||
|
Instances of abusive, harassing, or otherwise unacceptable behavior
|
||||||
|
may be reported to the community leaders responsible for enforcement
|
||||||
|
at [daniel@ekloef.se](mailto:daniel@ekloef.se). All complaints will
|
||||||
|
be reviewed and investigated promptly and fairly.
|
||||||
|
|
||||||
|
All community leaders are obligated to respect the privacy and security of the
|
||||||
|
reporter of any incident.
|
||||||
|
|
||||||
|
The consequences for Code of Conduct violations will be decided upon and
|
||||||
|
enforced by community leaders. These may include a formal warning, a temporary
|
||||||
|
ban from community spaces, a permanent ban from community spaces, etc.
|
||||||
|
|
||||||
|
There are no hard and fast rules for exactly what behavior in which space will
|

## Overview
|
||||||
|
|
||||||
|
foot makes use of a couple of libraries I have developed:
|
||||||
|
[tllist](https://codeberg.org/dnkl/tllist) and
|
||||||
|
[fcft](https://codeberg.org/dnkl/fcft). As such, they will most likely
|
||||||
|
not have been installed already. You can either install them as system
|
||||||
|
libraries or build them as _subprojects_ in foot.
|
||||||
|
|
||||||
|
When building foot, they will first be searched for as system
|
||||||
|
libraries. If **found**, foot will link dynamically against them.
|
||||||
|
If **not** found, meson will attempt to download and build them as
|
||||||
|
subprojects.
|
||||||
|
|
||||||
|
|
||||||
|
## Requirements
|
||||||
|
|
||||||
|
### Running
|
||||||
|
|
||||||
|
* UTF-8 locale
|
||||||
|
* fontconfig
|
||||||
|
* freetype
|
||||||
|
* pixman
|
||||||
|
* wayland (_client_ and _cursor_ libraries)
|
||||||
|
* xkbcommon
|
||||||
|
* utf8proc (_optional_, needed for grapheme clustering)
|
||||||
|
* libutempter (_optional_, needed for utmp logging on Linux)
|
||||||
|
* ulog (_optional_, needed for utmp logging on FreeBSD)
|
||||||
|
* [fcft](https://codeberg.org/dnkl/fcft) [^1]
|
||||||
|
|
||||||
|
[^1]: can also be built as subprojects, in which case they are
|
||||||
|
statically linked.
|
||||||
|
|
||||||
|
If you are packaging foot, you may also want to consider adding the
|
||||||
|
following **optional** dependencies:
|
||||||
|
|
||||||
|
* libnotify: desktop notifications by default uses `notify-send`.
|
||||||
|
* xdg-utils: URLs are by default launched with `xdg-open`.
|
||||||
|
* bash-completion: If you want completion for positional arguments.
|
||||||
|
|
||||||
|
### Building
|
||||||
|
|
||||||
|
In addition to the dev variant of the packages above, you need:
|
||||||
|
|
||||||
|
* meson
|
||||||
|
* ninja
|
||||||
|
* wayland protocols
|
||||||
|
* ncurses (needed to generate terminfo)
|
||||||
|
* scdoc (for man page generation, not needed if documentation is disabled)
|
||||||
|
* llvm (for PGO builds with Clang)
|
||||||
|
* [tllist](https://codeberg.org/dnkl/tllist) [^1]
|
||||||
|
* systemd (optional, foot will install systemd unit files if detected)
|
||||||
|
|
||||||
|
A note on compilers; in general, foot runs **much** faster when
|
||||||
|
compiled with gcc instead of clang. A profile-guided gcc build can be
|
||||||
|
more than twice as fast as a clang build.
|
||||||
|
|
||||||
|
**Note** GCC 10.1 has a performance regression that severely affects
|
||||||
|
foot when doing PGO builds and building with `-O2`; it is about 30-40%
|
||||||
|
slower compared to GCC 9.3.
|
||||||
|
|
||||||
|
The work around is simple: make sure you build with `-O3`. This is the
|
||||||
|
default with `meson --buildtype=release`, but e.g. `makepkg` can
|
||||||
|
override it (`makepkg` uses `-O2` by default).
|
||||||
|
|
||||||
|
## Other
|
||||||
|
|
||||||
|
Foot uses _meson_. If you are unfamiliar with it, the official
|
||||||
|
[tutorial](https://mesonbuild.com/Tutorial.html) might be a good
|
||||||
|
starting point.
|
||||||
|
|
||||||
|
A note on terminfo; the terminfo database exposes terminal
|
||||||
|
capabilities to the applications running inside the terminal. As such,
|
||||||
|
it is important that the terminfo used reflects the actual
|
||||||
|
terminal. Using the `xterm-256color` terminfo will, in many cases,
|
||||||
|
work, but I still recommend using foot's own terminfo. There are two
|
||||||
|
reasons for this:
|
||||||
|
|
||||||
|
* foot's terminfo contains a couple of non-standard capabilities,
|
||||||
|
used by e.g. tmux.
|
||||||
|
* New capabilities added to the `xterm-256color` terminfo could
|
||||||
|
potentially break foot.
|
||||||
|
* There may be future additions or changes to foot's terminfo.
|
||||||
|
|
||||||
|
As of ncurses 2021-07-31, ncurses includes a version of foot's
|
||||||
|
terminfo. **The recommendation is to use those**, and only install the
|
||||||
|
terminfo definitions from this git repo if the system's ncurses
|
||||||
|
predates 2021-07-31.
|
||||||
|
|
||||||
|
But, note that the foot terminfo definitions in ncurses' lack the
|
||||||
|
non-standard capabilities. This mostly affects tmux; without them,
|
||||||
|
`terminal-overrides` must be configured to enable truecolor
|
||||||
|
support. For this reason, it _is_ possible to install "our" terminfo
|
||||||
|
definitions as well, either in a non-default location, or under a
|
||||||
|
different name.
|
||||||
|
|
||||||
|
Both have their set of issues. When installing to a non-default
|
||||||
|
location, foot will set the environment variable `TERMINFO` in the
|
||||||
|
child process. However, there are many situations where this simply
|
||||||
|
does not work. See https://codeberg.org/dnkl/foot/issues/695 for
|
||||||
|
details.
|
||||||
|
|
||||||
|
Installing them under a different name generally works well, but will
|
||||||
|
break applications that check if `$TERM == foot`.
|
||||||
|
|
||||||
|
Hence the recommendation to simply use ncurses' terminfo definitions
|
||||||
|
if available.
|
||||||
|
|
||||||
|
If packaging "our" terminfo definitions, I recommend doing that as a
|
||||||
|
separate package, to allow them to be installed on remote systems
|
||||||
|
without having to install foot itself.
|
||||||
|
|
||||||
|
|
||||||
|
### Setup
|
||||||
|
|
||||||
|
To build, first, create a build directory, and switch to it:
|
||||||
|
```sh
|
||||||
|
mkdir -p bld/release && cd bld/release
|
||||||
|
```
|
||||||
|
|
||||||
|
### Options
|
||||||
|
|
||||||
|
Available compile-time options:
|
||||||
|
|
||||||
|
| Option | Type | Default | Description | Extra dependencies |
|
||||||
|
|--------------------------------------|---------|-------------------------|---------------------------------------------------------------------------------|---------------------|
|
||||||
|
| `-Ddocs` | feature | `auto` | Builds and install documentation | scdoc |
|
||||||
|
| `-Dtests` | bool | `true` | Build tests (adds a `ninja test` build target) | None |
|
||||||
|
| `-Dime` | bool | `true` | Enables IME support | None |
|
||||||
|
| `-Dgrapheme-clustering` | feature | `auto` | Enables grapheme clustering | libutf8proc |
|
||||||
|
| `-Dterminfo` | feature | `enabled` | Build and install terminfo files | tic (ncurses) |
|
||||||
|
| `-Ddefault-terminfo` | string | `foot` | Default value of `TERM` | None |
|
||||||
|
| `-Dterminfo-base-name` | string | `-Ddefault-terminfo` | Base name of the generated terminfo files | None |
|
||||||
|
| `-Dcustom-terminfo-install-location` | string | `${datadir}/terminfo` | Value to set `TERMINFO` to | None |
|
||||||
|
| `-Dsystemd-units-dir` | string | `${systemduserunitdir}` | Where to install the systemd service files (absolute) | None |
|
||||||
|
| `-Dutmp-backend` | combo | `auto` | Which utmp backend to use (`none`, `libutempter`, `ulog` or `auto`) | libutempter or ulog |
|
||||||
|
| `-Dutmp-default-helper-path` | string | `auto` | Default path to utmp helper binary. `auto` selects path based on `utmp-backend` | None |
|
||||||
|
|
||||||
|
Documentation includes the man pages, readme, changelog and license
|
||||||
|
files.
|
||||||
|
|
||||||
|
`-Ddefault-terminfo`: I strongly recommend leaving the default
|
||||||
|
value. Use this option if you plan on installing the terminfo files
|
||||||
|
under a different name. Setting this changes the default value of
|
||||||
|
`$TERM`, and the names of the terminfo files (if
|
||||||
|
`-Dterminfo=enabled`).
|
||||||
|
|
||||||
|
If you want foot to use the terminfo files from ncurses, but still
|
||||||
|
package foot's own terminfo files under a different name, you can use
|
||||||
|
the `-Dterminfo-base-name` option. Many distributions use the name
|
||||||
|
`foot-extra`, and thus it might be a good idea to reuse that:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
meson ... -Ddefault-terminfo=foot -Dterminfo-base-name=foot-extra
|
||||||
|
```
|
||||||
|
(or just leave out `-Ddefault-terminfo`, since it defaults to `foot` anyway).
|
||||||
|
|
||||||
|
Finally, `-Dcustom-terminfo-install-location` enables foot's terminfo
|
||||||
|
to co-exist with ncurses' version, without changing the terminfo
|
||||||
|
names. The idea is that you install foot's terminfo to a non-standard
|
||||||
|
location, for example `/usr/share/foot/terminfo`. Use
|
||||||
|
`-Dcustom-terminfo-install-location` to tell foot where the terminfo
|
||||||
|
is. Foot will set the environment variable `TERMINFO` to this value
|
||||||
|
(with `${prefix}` added). The value is **relative to ${prefix}**.
|
||||||
|
|
||||||
|
Note that there are several issues with this approach:
|
||||||
|
https://codeberg.org/dnkl/foot/issues/695.
|
||||||
|
|
||||||
|
If left unset, foot will **not** set or modify `TERMINFO`.
|
||||||
|
|
||||||
|
`-Dterminfo` can be used to disable building the terminfo definitions
|
||||||
|
in the meson build. It does **not** change the default value of
|
||||||
|
`TERM`, and it does **not** disable `TERMINFO`, if
|
||||||
|
`-Dcustom-terminfo-install-location` has been set. Use this if
|
||||||
|
packaging the terminfo definitions in a separate package (and the
|
||||||
|
build script isn't shared with the 'foot' package).
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
meson --prefix=/usr -Dcustom-terminfo-install-location=lib/foot/terminfo
|
||||||
|
```
|
||||||
|
|
||||||
|
The above tells foot its terminfo definitions will be installed to
|
||||||
|
`/usr/lib/foot/terminfo`. This is the value foot will set the
|
||||||
|
`TERMINFO` environment variable to.
|
||||||
|
|
||||||
|
If `-Dterminfo` is enabled (the default), then the terminfo files will
|
||||||
|
be built as part of the regular build process, and installed to the
|
||||||
|
specified location.
|
||||||
|
|
||||||
|
Packagers may want to set `-Dterminfo=disabled`, and manually build
|
||||||
|
and [install the terminfo](#terminfo) files instead.
|
||||||
|
|
||||||
|
|
||||||
|
### Release build
|
||||||
|
|
||||||
|
Below are instructions for building foot either [size
|
||||||
|
optimized](#size-optimized), [performance
|
||||||
|
optimized](performance-optimized-non-pgo), or performance
|
||||||
|
optimized using [PGO](#performance-optimized-pgo).
|
||||||
|
|
||||||
|
PGO - _Profile Guided Optimization_ - is a way to optimize a program
|
||||||
|
better than `-O3` can, and is done by compiling foot twice: first to
|
||||||
|
generate an instrumented version which is used to run a payload that
|
||||||
|
exercises the performance critical parts of foot, and then a second
|
||||||
|
time to rebuild foot using the generated profiling data to guide
|
||||||
|
optimization.
|
||||||
|
|
||||||
|
In addition to being faster, PGO builds also tend to be smaller than
|
||||||
|
regular `-O3` builds.
|
||||||
|
|
||||||
|
|
||||||
|
#### Size optimized
|
||||||
|
|
||||||
|
To optimize for size (i.e. produce a small binary):
|
||||||
|
|
||||||
|
```sh
|
||||||
|
export CFLAGS="$CFLAGS -Os"
|
||||||
|
meson --buildtype=release --prefix=/usr -Db_lto=true ../..
|
||||||
|
ninja
|
||||||
|
ninja test
|
||||||
|
ninja install
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Performance optimized, non-PGO
|
||||||
|
|
||||||
|
To do a regular, non-PGO build optimized for performance:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
export CFLAGS="$CFLAGS -O3"
|
||||||
|
meson --buildtype=release --prefix=/usr -Db_lto=true ../..
|
||||||
|
ninja
|
||||||
|
ninja test
|
||||||
|
ninja install
|
||||||
|
```
|
||||||
|
|
||||||
|
Use `-O2` instead of `-O3` if you prefer a slightly smaller (and
|
||||||
|
slower!) binary.
|
||||||
|
|
||||||
|
|
||||||
|
#### Performance optimized, PGO
|
||||||
|
|
||||||
|
There are a lot more steps involved in a PGO build, and for this
|
||||||
|
reason there are a number of helper scripts available.
|
||||||
|
|
||||||
|
`pgo/pgo.sh` is a standalone script that pieces together the other
|
||||||
|
scripts in the `pgo` directory to do a complete PGO build. This script
|
||||||
|
is intended to be used when doing manual builds.
|
||||||
|
|
||||||
|
Note that all "full" PGO builds (which `auto` will prefer, if
|
||||||
|
possible) **require** `LC_CTYPE` to be set to an UTF-8 locale. This is
|
||||||
|
**not** done automatically.
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
cd foot
|
||||||
|
./pgo/pgo.sh auto . /tmp/foot-pgo-build-output
|
||||||
|
```
|
||||||
|
|
||||||
|
(run `./pgo/pgo.sh` to get help on usage)
|
||||||
|
|
||||||
|
It supports a couple of different PGO builds; partial (covered in
|
||||||
|
detail below), full (also covered in detail below), and (full)
|
||||||
|
headless builds using Sway or cage.
|
||||||
|
|
||||||
|
Packagers may want to use it as inspiration, but may choose to support
|
||||||
|
only a specific build type; e.g. full/headless with Sway.
|
||||||
|
|
||||||
|
To do a manual PGO build, instead of using the script(s) mentioned
|
||||||
|
above, detailed instructions follows:
|
||||||
|
|
||||||
|
First, configure the build directory:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
export CFLAGS="$CFLAGS -O3"
|
||||||
|
meson --buildtype=release --prefix=/usr -Db_lto=true ../..
|
||||||
|
```
|
||||||
|
|
||||||
|
It is **very** important `-O3` is being used here, as GCC-10.1.x and
|
||||||
|
later have a regression where PGO with `-O2` is **much** slower.
|
||||||
|
|
||||||
|
Clang users **must** add `-Wno-ignored-optimization-argument` to
|
||||||
|
`CFLAGS`.
|
||||||
|
|
||||||
|
Then, tell meson we want to _generate_ profiling data, and build:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
meson configure -Db_pgo=generate
|
||||||
|
ninja
|
||||||
|
ninja test
|
||||||
|
```
|
||||||
|
|
||||||
|
Next, we need to actually generate the profiling data.
|
||||||
|
|
||||||
|
There are two ways to do this: a [partial PGO build using a PGO
|
||||||
|
helper](#partial-pgo) binary, or a [full PGO build](#full-pgo) by
|
||||||
|
running the real foot binary. The latter has slightly better results
|
||||||
|
(i.e. results in a faster binary), but must be run in a Wayland
|
||||||
|
session.
|
||||||
|
|
||||||
|
A full PGO build also tends to be smaller than a partial build.
|
||||||
|
|
||||||
|
|
||||||
|
##### Partial PGO
|
||||||
|
|
||||||
|
This method uses a PGO helper binary that links against the VT parser
|
||||||
|
only. It is similar to a mock test; it instantiates a dummy terminal
|
||||||
|
instance and then directly calls the VT parser with stimuli.
|
||||||
|
|
||||||
|
It explicitly does **not** include the Wayland backend and as such, it
|
||||||
|
does not require a running Wayland session. The downside is that not
|
||||||
|
all code paths in foot is exercised. In particular, the **rendering**
|
||||||
|
code is not. As a result, the final binary built using this method is
|
||||||
|
slightly slower than when doing a [full PGO](#full-pgo) build.
|
||||||
|
|
||||||
|
We will use the `pgo` binary along with input corpus generated by
|
||||||
|
`scripts/generate-alt-random-writes.py`:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
./utils/xtgettcap
|
||||||
|
./footclient --version
|
||||||
|
./foot --version
|
||||||
|
tmp_file=$(mktemp)
|
||||||
|
../../scripts/generate-alt-random-writes \
|
||||||
|
--rows=67 \
|
||||||
|
--cols=135 \
|
||||||
|
--scroll \
|
||||||
|
--scroll-region \
|
||||||
|
--colors-regular \
|
||||||
|
--colors-bright \
|
||||||
|
--colors-256 \
|
||||||
|
--colors-rgb \
|
||||||
|
--attr-bold \
|
||||||
|
--attr-italic \
|
||||||
|
--attr-underline \
|
||||||
|
--sixel \
|
||||||
|
${tmp_file}
|
||||||
|
./pgo ${tmp_file} ${tmp_file} ${tmp_file}
|
||||||
|
rm ${tmp_file}
|
||||||
|
```
|
||||||
|
|
||||||
|
The first step, running `./foot --version` and `./footclient
|
||||||
|
--version` etc, might seem unnecessary, but is needed to ensure we
|
||||||
|
have _some_ profiling data for functions not covered by the PGO helper
|
||||||
|
binary, for **all** binaries. Without this, the final link phase will
|
||||||
|
fail.
|
||||||
|
|
||||||
|
The snippet above then creates an (empty) temporary file. Then, it
|
||||||
|
runs a script that generates random escape sequences (if you cat
|
||||||
|
`${tmp_file}` in a terminal, you'll see random colored characters all
|
||||||
|
over the screen). Finally, we feed the randomly generated escape
|
||||||
|
sequences to the PGO helper. This is what generates the profiling data
|
||||||
|
used in the next step.
|
||||||
|
|
||||||
|
You are now ready to [use the generated PGO
|
||||||
|
data](#use-the-generated-pgo-data).
|
||||||
|
|
||||||
|
|
||||||
|
##### Full PGO
|
||||||
|
|
||||||
|
This method requires a running Wayland session.
|
||||||
|
|
||||||
|
We will use the script `scripts/generate-alt-random-writes.py`:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
./utils/xtgettcap
|
||||||
|
./footclient --version
|
||||||
|
foot_tmp_file=$(mktemp)
|
||||||
|
./foot \
|
||||||
|
--config=/dev/null \
|
||||||
|
--override tweak.grapheme-shaping=no \
|
||||||
|
--term=xterm \
|
||||||
|
sh -c "<path-to-generate-alt-random-writes.py> --scroll --scroll-region --colors-regular --colors-bright --colors-256 --colors-rgb --attr-bold --attr-italic --attr-underline --sixel ${foot_tmp_file} && cat ${foot_tmp_file}"
|
||||||
|
rm ${foot_tmp_file}
|
||||||
|
```
|
||||||
|
|
||||||
|
You should see a foot window open up, with random colored text. The
|
||||||
|
window should close after ~1-2s.
|
||||||
|
|
||||||
|
The first step, `./utils/xtgettcap && ./footclient --version`
|
||||||
|
might seem unnecessary, but is needed to ensure we have _some_
|
||||||
|
profiling data for **all** binaries we build. Without this, the final
|
||||||
|
link phase will fail.
|
||||||
|
|
||||||
|
|
||||||
|
##### Use the generated PGO data
|
||||||
|
|
||||||
|
Now that we have _generated_ PGO data, we need to rebuild foot. This
|
||||||
|
time telling meson (and ultimately gcc/clang) to _use_ the PGO data.
|
||||||
|
|
||||||
|
If using Clang, now do (this requires _llvm_ to have been installed):
|
||||||
|
|
||||||
|
```sh
|
||||||
|
llvm-profdata merge default_*profraw --output=default.profdata
|
||||||
|
```
|
||||||
|
|
||||||
|
Next, tell meson to _use_ the profile data we just generated, and rebuild:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
meson configure -Db_pgo=use
|
||||||
|
ninja
|
||||||
|
ninja test
|
||||||
|
```
|
||||||
|
|
||||||
|
Continue reading in [Running the new build](#running-the-new-build)
|
||||||
|
|
||||||
|
|
||||||
|
### Debug build
|
||||||
|
|
||||||
|
```sh
|
||||||
|
meson --buildtype=debug ../..
|
||||||
|
ninja
|
||||||
|
ninja test
|
||||||
|
```
|
||||||
|
|
||||||
|
### Terminfo
|
||||||
|
|
||||||
|
By default, building foot also builds the terminfo files. If packaging
|
||||||
|
the terminfo files in a separate package, it might be easier to simply
|
||||||
|
disable the terminfo files in the regular build, and compile the
|
||||||
|
terminfo files manually instead.
|
||||||
|
|
||||||
|
To build the terminfo files, run:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
sed 's/@default_terminfo@/foot/g' foot.info | \
|
||||||
|
tic -o <output-directory> -x -e foot,foot-direct -
|
||||||
|
```
|
||||||
|
|
||||||
|
Where _"output-directory"_ **must** match the value passed to
|
||||||
|
`-Dcustom-terminfo-install-location` in the foot build. If
|
||||||
|
`-Dcustom-terminfo-install-location` has not been set, `-o
|
||||||
|
<output-directory>` can simply be omitted.
|
||||||
|
|
||||||
|
Or, if packaging:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
tic -o ${DESTDIR}/usr/share/terminfo ...
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
### Running the new build
|
||||||
|
|
||||||
|
You can now run it directly from the build directory:
|
||||||
|
```sh
|
||||||
|
./foot
|
||||||
|
```
|
||||||
|
|
||||||
|
Or, if you did not install the terminfo definitions:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
./foot --term xterm-256color
|
||||||
|
```

# CSI
|
||||||
|
|
||||||
|
All sequences begin with *\\E[*, sometimes abbreviated "CSI". Spaces
|
||||||
|
are used in the sequence strings to make them easier to read, but are
|
||||||
|
not actually part of the string (i.e. *\\E[ 1 m* is really *\\E[1m*).
|
||||||
|
|
||||||
|
## SGR
|
||||||
|
|
||||||
|
All SGR sequences are in the form *\\E[* _N_ *m*, where _N_ is a decimal
|
||||||
|
number - the _parameter_. Multiple parameters can be combined in a
|
||||||
|
single CSI sequence by separating them with semicolons: *\\E[ 1;2;3
|
||||||
|
m*.

|
||||||
|
|
||||||
|
## Indexed and RGB colors (256-color palette and 24-bit colors)
|
||||||
|
|
||||||
|
Foot supports both the new sub-parameter based variants, and the older
|
||||||
|
parameter based variants for setting foreground and background colors.
|
||||||
|
|
||||||
|
Indexed colors:
|
||||||
|
|
||||||
|
- *\\E[ 38 : 5 :* _idx_ *m*
|
||||||
|
- *\\E[ 38 ; 5 ;* _idx_ *m*
|
||||||
|
|
||||||
|
RGB colors:
|
||||||
|
|
||||||
|
- *\\E[ 38 : 2 :* _cs_ *:* _r_ *:* _g_ *:* _b_ *m*
|
||||||
|
- *\\E[ 38 : 2 :* _r_ *:* _g_ *:* _b_ *m*
|
||||||
|
- *\\E[ 38 ; 2 ;* _r_ *;* _g_ *;* _b_ *m*
|
||||||
|
|
||||||
|
The first variant is the "correct" one (and foot also recognizes, but
|
||||||
|
ignores, the optional _tolerance_ parameters).
|
||||||
|
|
||||||
|
The second one is allowed since many programs "forget" the color space
|
||||||
|
ID, _cs_.
|
||||||
|
|
||||||
|
The sub-parameter based variants are preferred, and are what foot's
|
||||||
|
*terminfo*(5) entry uses.
|
||||||
|
|
||||||
|
## Private Modes
|
||||||
|
|
||||||
|
There are several Boolean-like "modes" that affect certain aspects
|
||||||
|
of the terminal's behavior. These modes can be manipulated with the
|
||||||
|
following 4 escape sequences:
|
||||||
|
|
||||||
|
[[ *Sequence*
|
||||||
|
:[ *Name*
|
||||||
|
:< *Description*
|
||||||
|
| \\E[ ? _Pm_ h
|
||||||
|
: DECSET
|
||||||
|
: Enable private mode
|
||||||
|
| \\E[ ? _Pm_ l
|
||||||
|
: DECRST
|
||||||
|
: Disable private mode
|
||||||
|
| \\E[ ? _Pm_ s
|
||||||
|
: XTSAVE
|
||||||
|
: Save private mode
|
||||||
|
| \\E[ ? _Pm_ r
|
||||||
|
: XTRESTORE
|
||||||
|
: Restore private mode
|
||||||
|
|
||||||
|
|
||||||
|
The _Pm_ parameter in the above sequences denotes a numerical ID
|
||||||
|
that corresponds to one of the following modes:
|
||||||
|

# NAME
|
||||||
|
|
||||||
|
foot - Wayland terminal emulator
|
||||||
|
|
||||||
|
# SYNOPSIS
|
||||||
|
|
||||||
|
*foot* [_OPTIONS_]++
|
||||||
|
*foot* [_OPTIONS_] <_command_> [_COMMAND OPTIONS_]
|
||||||
|
|
||||||
|
All trailing (non-option) arguments are treated as a command, and its
|
||||||
|
arguments, to execute (instead of the default shell).
|
||||||
|
|
||||||
|
# DESCRIPTION
|
||||||
|
|
||||||
|
*foot* is a Wayland terminal emulator. Running it without arguments
|
||||||
|
will start a new terminal window with your default shell.
|
||||||
|
|
||||||
|
You can override the default shell by appending a custom command to
|
||||||
|
the foot command line
|
||||||
|
|
||||||
|
*foot htop*
|
||||||
|
|
||||||
|
# OPTIONS
|
||||||
|
|
||||||
|
*-c*,*--config*=_PATH_
|
||||||
|
Path to configuration file, see *foot.ini*(5) for details.
|
||||||
|
|
||||||
|
The configuration file is automatically passed to new terminals
|
||||||
|
spawned via *spawn-terminal* (see *foot.ini*(5)).
|
||||||
|
|
||||||
|
*-C*,*--check-config*
|
||||||
|
Verify configuration and then exit with 0 if ok, otherwise exit
|
||||||
|
with 230 (see *EXIT STATUS*).
|
||||||
|
|
||||||
|
*-o*,*--override*=[_SECTION_.]_KEY_=_VALUE_
|
||||||
|
Override an option set in the configuration file. If _SECTION_ is not
|
||||||
|
given, defaults to _main_.
|
||||||
|
|
||||||
|
*-f*,*--font*=_FONT_
|
||||||
|
Comma separated list of fonts to use, in fontconfig format (see
|
||||||
|
*FONT FORMAT*).
|
||||||
|
|
||||||
|
The first font is the primary font. The remaining fonts are
|
||||||
|
fallback fonts that will be used whenever a glyph cannot be found
|
||||||
|
in the primary font.
|
||||||
|
|
||||||
|
The fallback fonts are searched in the order they appear. If a
|
||||||
|
glyph cannot be found in any of the fallback fonts, the dynamic
|
||||||
|
fallback list from fontconfig (for the primary font) is
|
||||||
|
searched.
|
||||||
|
|
||||||
|
Default: _monospace_.
|
||||||
|
|
||||||
|
*-w*,*--window-size-pixels*=_WIDTHxHEIGHT_
|
||||||
|
Set initial window width and height, in pixels. Default: _700x500_.
|
||||||
|
|
||||||
|
*-W*,*--window-size-chars*=_WIDTHxHEIGHT_
|
||||||
|
Set initial window width and height, in characters. Default: _not set_.
|
||||||
|
|
||||||
|
*-t*,*--term*=_TERM_
|
||||||
|
Value to set the environment variable *TERM* to (see *TERMINFO*
|
||||||
|
and *ENVIRONMENT*). Default: _@default_terminfo@_.
|
||||||
|
|
||||||
|
*-T*,*--title*=_TITLE_
|
||||||
|
Initial window title. Default: _foot_.
|
||||||
|
|
||||||
|
*-a*,*--app-id*=_ID_
|
||||||
|
Value to set the *app-id* property on the Wayland window
|
||||||
|
to. Default: _foot_ (normal mode), or _footclient_ (server mode).
|
||||||
|
|
||||||
|
*toplevel-tag*=_TAG_
|
||||||
|
Value to set the *toplevel-tag* property on the Wayland window
|
||||||
|
to. The compositor can use this value for session management,
|
||||||
|
window rules etc. Default: _not set_
|
||||||
|
|
||||||
|
*-m*,*--maximized*
|
||||||
|
Start in maximized mode. If both *--maximized* and *--fullscreen*
|
||||||
|
are specified, the _last_ one takes precedence.
|
||||||
|
|
||||||
|
*-F*,*--fullscreen*
|
||||||
|
Start in fullscreen mode. If both *--maximized* and *--fullscreen*
|
||||||
|
are specified, the _last_ one takes precedence.
|
||||||
|
|
||||||
|
*-L*,*--login-shell*
|
||||||
|
Start a login shell, by prepending a '-' to argv[0].
|
||||||
|
|
||||||
|
*--pty*
|
||||||
|
Display an existing pty instead of creating one. This is useful
|
||||||
|
for interacting with VM consoles.
|
||||||
|
|
||||||
|
This option is not currently supported in combination with
|
||||||
|
*-s*,*--server*.
|
||||||
|
|
||||||
|
*-D*,*--working-directory*=_DIR_
|
||||||
|
Initial working directory for the client application. Default:
|
||||||
|
_CWD of foot_.
|
||||||
|
|
||||||
|
*-s*,*--server*[=_PATH_|_FD_]
|
||||||
|
Run as a server. In this mode, a single foot instance hosts
|
||||||
|
multiple terminals (windows). Use *footclient*(1) to launch new
|
||||||
|
terminals.
|
||||||
|
|
||||||
|
This saves some memory since for example fonts and glyph caches
|
||||||
|
can be shared between the terminals.
|
||||||
|
|
||||||
|
It also saves upstart time since the config has already been
|
||||||
|
loaded and parsed, and most importantly, fonts have already been
|
||||||
|
loaded (and their glyph caches are likely to already have been
|
||||||
|
populated).
|
||||||
|
|
||||||
|
Each terminal will have its own rendering threads, but all Wayland
|
||||||
|
communication, as well as input/output to the shell, is
|
||||||
|
multiplexed in the main thread. Thus, this mode might result in
|
||||||
|
slightly worse performance when multiple terminals are under heavy
|
||||||
|
load.
|
||||||
|
|
||||||
|
Also be aware that should one terminal crash, it will take all the
|
||||||
|
others with it.
|
||||||
|
|
||||||
|
The default path is
|
||||||
|
*$XDG\_RUNTIME\_DIR/foot-$WAYLAND\_DISPLAY.sock*.
|
||||||
|
|
||||||
|
If *$XDG\_RUNTIME\_DIR* is not set, the default path is instead
|
||||||
|
*/tmp/foot.sock*.
|
||||||
|
|
||||||
|
If *$XDG\_RUNTIME\_DIR* is set, but *$WAYLAND\_DISPLAY* is not,
|
||||||
|
the default path is *$XDG\_RUNTIME\_DIR/foot.sock*.
|
||||||
|
|
||||||
|
Note that if you change the default, you will also need to use the
|
||||||
|
*--server-socket* option in *footclient*(1) and point it to your
|
||||||
|
custom socket path.
|
||||||
|
|
||||||
|
If the argument is a number, foot will interpret it as the file descriptor
|
||||||
|
of a socket provided by a supervision daemon (such as systemd or s6), and
|
||||||
|
use that socket as it's own.
|
||||||
|
|
||||||
|
Two systemd units (foot-server.{service,socket}) are provided to use that
|
||||||
|
feature with systemd. To use socket activation, only enable the
|
||||||
|
socket unit.
|
||||||
|
|
||||||
|
Note that starting *foot --server* as a systemd service will use
|
||||||
|
the environment of the systemd user instance; thus, you'll need
|
||||||
|
to import *$WAYLAND_DISPLAY* in it using *systemctl --user
|
||||||
|
import-environment WAYLAND_DISPLAY*.
|
||||||
|
|
||||||
|
*-H*,*--hold*
|
||||||
|
Remain open after child process exits.
|
||||||
|
|
||||||
|
*-p*,*--print-pid*=_FILE_|_FD_
|
||||||
|
Print PID to this file, or FD, when successfully started. The file
|
||||||
|
(or FD) is closed immediately after writing the PID. When a _FILE_
|
||||||
|
as been specified, the file is unlinked at exit.
|
||||||
|
|
||||||
|
This option can only be used in combination with *-s*,*--server*.
|
||||||
|
|
||||||
|
*-d*,*--log-level*={*info*,*warning*,*error*,*none*}
|
||||||
|
Log level, used both for log output on stderr as well as
|
||||||
|
syslog. Default: _warning_.
|
||||||
|
|
||||||
|
*-l*,*--log-colorize*=[{*never*,*always*,*auto*}]
|
||||||
|
Enables or disables colorization of log output on stderr. Default:
|
||||||
|
_auto_.
|
||||||
|
|
||||||
|
*-S*,*--log-no-syslog*
|
||||||
|
Disables syslog logging. Logging is only done on stderr. This
|
||||||
|
option can only be used in combination with *-s*,*--server*.
|
||||||
|
|
||||||
|
*-v*,*--version*
|
||||||
|
Show the version number and quit.
|
||||||
|
|
||||||
|
*-e*
|
||||||
|
Ignored; for compatibility with *xterm -e*.
|
||||||
|
|
||||||
|
This option was added in response to several program launchers
|
||||||
|
passing *-e* to arbitrary terminals, under the assumption that
|
||||||
|
they all implement the same semantics for it as *xterm*(1).
|
||||||
|
Ignoring it allows foot to be invoked as e.g. *foot -e man foot*
|
||||||
|
with the same results as with xterm, instead of producing an
|
||||||
|
"invalid option" error.
|
||||||

|
||||||
|
|
||||||
|
## MOUSE SHORTCUTS
|
||||||
|
|
||||||
|
*left*, single-click
|
||||||
|
Drag to select; when released, the selected text is copied to the
|
||||||
|
_primary_ selection. This feature is normally *disabled* whenever
|
||||||
|
the client has enabled _mouse tracking_, but can be forced by
|
||||||
|
holding *shift*.
|
||||||
|
|
||||||
|
Holding *ctrl* will create a block selection.
|
||||||
|
|
||||||
|
*left*, double-click
|
||||||
|
Selects the _word_ (separated by spaces, period, comma,
|
||||||
|
parenthesis etc) under the pointer. Hold *ctrl* to select
|
||||||
|
everything under the pointer up to, and until, the next space
|
||||||
|
characters.
|
||||||
|
|
||||||
|
*left*, triple-click
|
||||||
|
Selects the everything between enclosing quotes, or the entire row
|
||||||
|
if not inside a quote.
|
||||||
|
|
||||||

*left*, quad-click
|
||||||
|
Selects the entire row
|
||||||
|
|
||||||
|
*middle*
|
||||||
|
Paste from the _primary_ selection
|
||||||
|
|
||||||
|
*right*
|
||||||
|
Extend current selection. Clicking immediately extends the
|
||||||
|
selection, while hold-and-drag allows you to interactively resize
|
||||||
|
the selection.
|
||||||
|
|
||||||
|
*ctrl*+*right*
|
||||||
|
Extend the current selection, but force it to be character wise,
|
||||||
|
rather than depending on the original selection mode.
|
||||||
|
|
||||||
|
*wheel*
|
||||||
|
Scroll up/down in history
|
||||||
|
|

|
Emulates mouse left button click.
|
||||||
|
|
||||||
|
*drag*
|
||||||
|
Scrolls up/down in history.
|
||||||
|
|
||||||
|
Holding for a while before dragging (time delay can be configured)
|
||||||
|
emulates mouse dragging with left button held.
|
||||||
|
|
||||||
|
|
||||||
|
# FONT FORMAT
|
||||||
|
|
||||||
|
The font is specified in FontConfig syntax. That is, a colon-separated
|
||||||
|
list of font name and font options.
|
||||||
|
|
||||||
|
_Examples_:
|
||||||
|
- Dina:weight=bold:slant=italic
|
||||||
|
- Courier New:size=12
|
||||||
|
|
||||||
|
# URLs
|
||||||
|
|
||||||
|
Foot supports URL detection. But, unlike many other terminal
|
||||||
|
emulators, where URLs are highlighted when they are hovered and opened
|
||||||
|
by clicking on them, foot uses a keyboard driven approach.
|
||||||
|
|
||||||
|
Pressing *ctrl*+*shift*+*o* enters _"Open URL mode"_, where all currently
|
||||||
|
visible URLs are underlined, and is associated with a
|
||||||
|
_"jump-label"_. The jump-label indicates the _key sequence_
|
||||||
|
(e.g. *"AF"*) to use to activate the URL.
|
||||||
|
|
||||||
|
The key binding can, of course, be customized, like all other key
|
||||||
|
bindings in foot. See *show-urls-launch* and *show-urls-copy* in
|
||||||
|
*foot.ini*(5).
|
||||||
|
|
||||||
|
*show-urls-launch* by default opens the URL with *xdg-open*. This can
|
||||||
|
be changed with the *url-launch* option.
|
||||||
|
|
||||||
|
*show-urls-copy* is an alternative to *show-urls-launch*, that changes
|
||||||
|
what activating a URL _does_; instead of opening it, it copies it to
|
||||||
|
the clipboard. It is unbound by default.
|
||||||
|
|
||||||
|
Jump label colors, the URL underline color, and the letters used in
|
||||||
|
the jump label key sequences can be configured.
|
||||||
|
|
||||||
|
# ALT/META CHARACTERS
|
||||||
|
|
||||||
|
By default, foot prefixes meta characters with *ESC*. This corresponds
|
||||||
|
to XTerm's *metaSendsEscape* option set to *true*.
|
||||||
|
|
||||||
|
This can be disabled programmatically with *\E[?1036l* (and enabled
|
||||||
|
again with *\E[?1036h*).
|
||||||
|
|
||||||
|
When disabled, foot will instead set the 8:th bit of meta character
|
||||||
|
and then UTF-8 encode it. This corresponds to XTerm's *eightBitMeta*
|
||||||
|
option set to *true*.
|
||||||
|
|
||||||
|
This can also be disabled programmatically with *rmm* (Reset Meta Mode,
|
||||||
|
*\E[?1034l*), and enabled again with *smm* (Set Meta Mode,
|
||||||
|
*\E[?1034h*).
|
||||||
|
|
||||||
|
# BACKSPACE
|
||||||
|
|
||||||
|
Foot transmits DEL (*^?*) on backspace. This corresponds to XTerm's
|
||||||
|
*backarrowKey* option set to *false*, and to DECBKM being _reset_.
|
||||||
|
|
||||||
|
To instead transmit BS (*^H*), press *ctrl*+*backspace*.
|
||||||
|
|
||||||
|
Note that foot does *not* implement DECBKM, and that the behavior
|
||||||
|
described above *cannot* be changed.
|
||||||
|
|
||||||
|
Finally, pressing *alt* will prefix the transmitted byte with ESC.
|
||||||
|
|
||||||
|
# KEYPAD
|
||||||
|
|
||||||
|
By default, *Num Lock* overrides the run-time configuration keypad
|
||||||
|
mode; when active, the keypad is always considered to be in
|
||||||
|
_numerical_ mode. This corresponds to XTerm's *numLock* option set to
|
||||||
|
*true*.
|
||||||
|
|
||||||
|
In this mode, the keypad keys always sends either numbers (Num Lock is
|
||||||
|
active) or cursor movement keys (up, down, left, right, page up, page
|
||||||
|
down etc).
|
||||||
|
|
||||||
|
This can be disabled programmatically with *\E[?1035l* (and enabled
|
||||||
|
again with *\E[?1035h*).
|
||||||
|
|
||||||
|
When disabled, the keypad sends custom escape sequences instead of
|
||||||
|
numbers, when in _application_ mode.
|
||||||

foot will search for a configuration file in the following locations,
|
||||||
|
in this order:
|
||||||
|
|
||||||
|
- *XDG_CONFIG_HOME/foot/foot.ini* (defaulting to
|
||||||
|
*$HOME/.config/foot/foot.ini* if unset)
|
||||||
|
- *XDG_CONFIG_DIRS/foot/foot.ini* (defaulting to
|
||||||
|
*/etc/xdg/foot/foot.ini* if unset)
|
||||||
|
|
||||||
|
An example configuration file containing all options with their default value
|
||||||
|
commented out will usually be installed to */etc/xdg/foot/foot.ini*.
|
||||||
|
|
||||||
|

# SHELL INTEGRATION
|
||||||
|
|
||||||
|
## Current working directory
|
||||||
|
|
||||||
|
New foot terminal instances (bound to *ctrl*+*shift*+*n* by default)
|
||||||
|
will open in the current working directory, if the shell in the
|
||||||
|
"parent" terminal reports directory changes.
|
||||||
|
|
||||||
|
This is done with the OSC-7 escape sequence. Most shells can be
|
||||||
|
scripted to do this, if they do not support it natively. See the wiki
|
||||||
|
(https://codeberg.org/dnkl/foot/wiki#user-content-spawning-new-terminal-instances-in-the-current-working-directory)
|
||||||
|
for details.
|
||||||
|
|
||||||
|
|
||||||
|
## Jumping between prompts
|
||||||
|
|
||||||
|
Foot can move the current viewport to focus prompts of already
|
||||||
|
executed commands (bound to *ctrl*+*shift*+*z*/*x* by default).
|
||||||
|
|
||||||
|
For this to work, the shell needs to emit an OSC-133;A
|
||||||
|
(*\\E]133;A\\E\\\\*) sequence before each prompt.
|
||||||
|
|
||||||
|
In zsh, one way to do this is to add a _precmd_ hook:
|
||||||
|
|
||||||
|
*precmd() {
|
||||||
|
print -Pn "\\e]133;A\\e\\\\"
|
||||||
|
}*
|
||||||
|
|
||||||
|
See the wiki
|
||||||
|
(https://codeberg.org/dnkl/foot/wiki#user-content-jumping-between-prompts)
|
||||||
|
for details, and examples for other shells.
|
||||||
|
|
||||||
|
## Piping last command's output
|
||||||
|
|
||||||
|
The key binding *pipe-command-output* can pipe the last command's
|
||||||
|
output to an application of your choice (similar to the other
|
||||||
|
*pipe-\** key bindings):
|
||||||
|
|
||||||
|
*\[key-bindings\]++
|
||||||
|
pipe-command-output=[sh -c "f=$(mktemp); cat - > $f; footclient emacsclient -nw $f; rm $f"] Control+Shift+g*
|
||||||
|
|
||||||
|
When pressing *ctrl*+*shift*+*g*, the last command's output is written
|
||||||
|
to a temporary file, then an emacsclient is started in a new
|
||||||
|
footclient instance. The temporary file is removed after the
|
||||||
|
footclient instance has closed.
|
||||||
|
|
||||||
|
For this to work, the shell must emit an OSC-133;C (*\\E]133;C\\E\\\\*)
|
||||||
|
sequence before command output starts, and an OSC-133;D
|
||||||
|
(*\\E]133;D\\E\\\\*) when the command output ends.
|
||||||
|
|
||||||
|
In fish, one way to do this is to add _preexec_ and _postexec_ hooks:
|
||||||
|
|
||||||
|
*function foot_cmd_start --on-event fish_preexec
|
||||||
|
echo -en "\\e]133;C\\e\\\\"
|
||||||
|
end*
|
||||||
|
|
||||||
|
*function foot_cmd_end --on-event fish_postexec
|
||||||
|
echo -en "\\e]133;D\\e\\\\"
|
||||||
|
end*
|
||||||
|
|
||||||
|
See the wiki
|
||||||
|
(https://codeberg.org/dnkl/foot/wiki#user-content-piping-last-commands-output)
|
||||||
|
for details, and examples for other shells
|
||||||
|
|
||||||
|
# TERMINFO
|
||||||
|
|
||||||
|
Client applications use the terminfo identifier specified by the
|
||||||
|
environment variable *TERM* (set by foot) to determine terminal
|
||||||
|
capabilities.
|
||||||
|
|
||||||
|
Foot has two terminfo definitions: *foot* and *foot-direct*, with
|
||||||
|
*foot* being the default.
|
||||||
|
|
||||||
|
The difference between the two is in the number of colors they
|
||||||
|
describe; *foot* describes 256 colors and *foot-direct* 16.7 million
|
||||||
|
colors (24-bit truecolor).
|
||||||
|
|
||||||
|
Note that using the *foot* terminfo does not limit the number of
|
||||||
|
usable colors to 256; applications can still use 24-bit RGB colors. In
|
||||||
|
fact, most applications work best with *foot* (including 24-bit
|
||||||
|
colors). Using *\*-direct* terminfo entries has been known to crash
|
||||||
|
some ncurses applications even.
|
||||||
|
|
||||||
|
There are however applications that need a *\*-direct* terminfo entry
|
||||||
|
for 24-bit support. Emacs is one such example.
|
||||||
|
|
||||||
|
While using either *foot* or *foot-direct* is strongly recommended, it
|
||||||
|
is possible to use e.g. *xterm-256color* as well. This can be useful
|
||||||
|
when remoting to a system where foot's terminfo entries cannot easily
|
||||||
|
be installed.
|
||||||
|
|
||||||
|
Note that terminfo entries can be installed in the user's home
|
||||||
|
directory. I.e. if you do not have root access, or if there is no
|
||||||
|
distro package for foot's terminfo entries, you can install foot's
|
||||||
|
terminfo entries manually, by copying *foot* and *foot-direct* to
|
||||||
|
*~/.terminfo/f/*.
|
||||||
|
|
||||||
|
# XTGETTCAP
|
||||||
|
|
||||||
|
*XTGETTCAP* is an escape sequence initially introduced by XTerm, and
|
||||||
|
also implemented (and extended, to some degree) by Kitty.
|
||||||
|
|
||||||
|
It allows querying the terminal for terminfo classic, file-based,
|
||||||
|
terminfo definition. For example, if all applications used this
|
||||||
|
feature, you would no longer have to install foot's terminfo on remote
|
||||||
|
hosts you SSH into.
|
||||||
|
|
||||||
|
XTerm's implementation (as of XTerm-370) only supports querying key
|
||||||
|
(as in keyboard keys) capabilities, and three custom capabilities:
|
||||||
|
|
||||||
|
- TN - terminal name
|
||||||
|
- Co - number of colors (alias for the colors capability)
|
||||||
|
- RGB - number of bits per color channel (different semantics from
|
||||||
|
the RGB capability in file-based terminfo definitions!).
|
||||||
|
|
||||||
|
Kitty has extended this, and also supports querying all integer and
|
||||||
|
string capabilities.
|
||||||
|
|
||||||
|
Foot supports this, and extends it even further, to also include
|
||||||
|
boolean capabilities. This means foot's entire terminfo can be queried
|
||||||
|
via *XTGETTCAP*.
|
||||||
|
|
||||||
|
Note that both Kitty and foot handles responses to multi-capability
|
||||||
|
queries slightly differently, compared to XTerm.
|
||||||
|
|
||||||
|
XTerm will send a single DCS reply, with ;-separated
|
||||||
|
capability/value pairs. There are a couple of issues with this:
|
||||||
|
|
||||||
|
- The success/fail flag in the beginning of the response is always 1
|
||||||
|
(success), unless the very first queried capability is invalid.
|
||||||
|
- XTerm will not respond at all to an invalid capability, unless it's
|
||||||
|
the first one in the XTGETTCAP query.
|
||||||
|
- XTerm will end the response at the first invalid capability.
|
||||||
|
|
||||||
|
In other words, if you send a large multi-capability query, you will
|
||||||
|
only get responses up to, but not including, the first invalid
|
||||||
|
capability. All subsequent capabilities will be dropped.
|
||||||
|
|
||||||
|
Kitty and foot on the other hand, send one DCS response for each
|
||||||
|
capability in the multi query. This allows us to send a proper
|
||||||
|
success/fail flag for each queried capability. Responses for all
|
||||||
|
queried capabilities are always sent. No queries are ever dropped.
|
||||||
|
|
||||||
|
# EXIT STATUS
|
||||||
|
|
||||||
|
Foot will exit with code 230 if there is a failure in foot itself.
|
||||||
|
|
||||||
|
In all other cases, the exit code is that of the client application
|
||||||
|
(i.e. the shell).
|
||||||
|
|
||||||
|
# ENVIRONMENT

option, when no explicit argument is given (see above).
|
||||||
|
|
||||||
|
*XCURSOR\_THEME*
|

|
|
||||||
|
*XCURSOR\_SIZE*
|
||||||
|
The size to use for *Xcursor*(3) pointers (typically set by the

|
|
||||||
|
## Variables set in the child process
|
||||||
|
|
||||||
|
*TERM*
|
||||||
|
terminfo/termcap identifier. This is used by client applications
|
||||||
|
to determine which capabilities a terminal supports. The value is
|
||||||
|
set according to either the *--term* command-line option or the
|
||||||
|
*term* config option in *foot.ini*(5).
|
||||||
|
|
||||||
|
*COLORTERM*
|
||||||
|
This variable is set to *truecolor*, to indicate to client
|
||||||
|
applications that 24-bit RGB colors are supported.
|
||||||
|
|
||||||
|
*PWD*
|
||||||
|
Current working directory (at the time of launching foot)
|
||||||
|
|
||||||
|
*SHELL*
|
||||||
|
Set to the launched shell, if the shell is valid (it is listed in
|
||||||
|
*/etc/shells*).
|
||||||
|
|
||||||
|
In addition to the variables listed above, custom environment
|
||||||
|
variables may be defined in *foot.ini*(5).
|
||||||
|
|
||||||
|
## Variables *unset* in the child process
|
||||||
|
|
||||||
|
*TERM_PROGRAM*
|
||||||
|
*TERM_PROGRAM_VERSION*
|
||||||
|
These environment variables are set by certain other terminal
|
||||||
|
emulators. We unset them, to prevent applications from
|
||||||
|
misdetecting foot.
|
||||||
|
|
||||||
|
In addition to the variables listed above, custom environment
|
||||||
|
variables to unset may be defined in *foot.ini*(5).
|
||||||
|
|
||||||
|
# Signals
|
||||||
|
|
||||||
|
The following signals have special meaning in foot:
|
||||||
|
|
||||||
|
- SIGUSR1: switch to the dark color theme (*[colors-dark]*).
|
||||||
|
- SIGUSR2: switch to the light color theme (*[colors-light]*).
|
||||||
|
|
||||||
|
Note: you can send SIGUSR1/SIGUSR2 to a *foot --server* process too,
|
||||||
|
in which case all client instances will switch theme. Furthermore, all
|
||||||
|
future client instances will also use the selected theme.
|
||||||
|
|
||||||
|
You can also send SIGUSR1/SIGUSR2 to a footclient instance, see
|
||||||
|
*footclient*(1) for details.

# NAME
|
||||||
|
footclient - start new terminals in a foot server
|
||||||
|
|
||||||
|
# SYNOPSIS
|
||||||
|
*footclient* [_OPTIONS_]++
|
||||||
|
*footclient* [_OPTIONS_] <_command_> [_COMMAND OPTIONS_]
|
||||||
|
|
||||||
|
All trailing (non-option) arguments are treated as a command, and its
|
||||||
|
arguments, to execute (instead of the default shell).
|
||||||
|
|
||||||
|
# DESCRIPTION
|
||||||
|
|
||||||
|
*footclient* is used together with *foot*(1) in *--server*
|
||||||
|
mode.
|
||||||
|
|
||||||
|
Running it without arguments will open a new terminal window (hosted
|
||||||
|
in the foot server), with your default shell. The exit code will be
|
||||||
|
that of the terminal. I.e *footclient* does not exit until the
|
||||||
|
terminal has terminated.
|
||||||
|
|
||||||
|

footclient's environment, instead of the server's.
|
||||||
|
|
||||||
|
Environment variables listed in the *Variables set in the child
|
||||||
|
process* section will be overwritten by the foot server. For
|
||||||
|
example, the new terminal will use *TERM* from the configuration,
|
||||||
|
not footclient's environment.
|
||||||
|
|
||||||

|
*-v*,*--version*
|
||||||
|
Show the version number and quit
|
||||||
|
|
||||||
|
*-e*
|
||||||
|
Ignored; for compatibility with *xterm -e*. See *foot*(1) for more
|
||||||
|
details.
|
||||||
|
|
||||||
|
# EXIT STATUS
|
||||||
|
|
||||||
|
Footclient will exit with code 220 if there is a failure in footclient
|
||||||
|
itself (for example, the server socket does not exist).
|
||||||
|
|
||||||
|
If *-N*,*--no-wait* is used, footclient exits with code 0 as soon as
|
||||||
|
the foot server has been instructed to open a new window.
|
||||||
|
|
||||||
|
If not, footclient may also exit with code 230. This indicates a
|
||||||
|
failure in the foot server.
|
||||||
|
|
||||||
|
In all other cases the exit code is that of the client application
|
||||||
|
(i.e. the shell).
|
||||||
|
|
||||||
|
# TERMINFO
|
||||||
|
|
||||||
|
Client applications use the terminfo identifier specified by the
|
||||||
|
environment variable *TERM* (set by foot) to determine terminal
|
||||||
|
capabilities.
|
||||||
|
|
||||||
|
Foot has two terminfo definitions: *foot* and *foot-direct*, with
|
||||||
|
*foot* being the default.
|
||||||
|
|
||||||
|
The difference between the two is in the number of colors they
|
||||||
|
describe; *foot* describes 256 colors and *foot-direct* 16.7 million
|
||||||
|
colors (24-bit truecolor).
|
||||||
|
|
||||||
|
Note that using the *foot* terminfo does not limit the number of
|
||||||
|
usable colors to 256; applications can still use 24-bit RGB colors. In
|
||||||
|
fact, most applications work best with *foot* (including 24-bit
|
||||||
|
colors)). Using *\*-direct* terminfo entries has been known to crash
|
||||||
|
some ncurses applications even.
|
||||||
|
|
||||||
|
There are however applications that need a *\*-direct* terminfo entry
|
||||||
|
for 24-bit support. Emacs is one such example.
|
||||||
|
|
||||||
|
While using either *foot* or *foot-direct* is strongly recommended, it
|
||||||
|
is possible to use e.g. *xterm-256color* as well. This can be useful
|
||||||
|
when remoting to a system where foot's terminfo entries cannot easily
|
||||||
|
be installed.
|
||||||
|
|
||||||
|
Note that terminfo entries can be installed in the user's home
|
||||||
|
directory. I.e. if you do not have root access, or if there is no
|
||||||
|
distro package for foot's terminfo entries, you can install foot's
|
||||||
|
terminfo entries manually, by copying *foot* and *foot-direct* to
|
||||||
|
*~/.terminfo/f/*.

||||||

||||||

# ENVIRONMENT
|
||||||
|
|
||||||
|
## Variables used by footclient
|
||||||
|
|
||||||
|
*XDG\_RUNTIME\_DIR*
|
||||||
|
Used to construct the default _PATH_ for the *--server-socket*
|
||||||
|
option, when no explicit argument is given (see above).
|
||||||
|
|
||||||
|
*WAYLAND\_DISPLAY*
|
||||||
|
Used to construct the default _PATH_ for the *--server-socket*
|
||||||
|
option, when no explicit argument is given (see above).
|
||||||
|
|
||||||
|
If the socket at default _PATH_ does not exist, *footclient* will
|
||||||
|
fallback to the less specific path, with the following priority:
|
||||||
|
*$XDG\_RUNTIME\_DIR/foot-$WAYLAND\_DISPLAY.sock*,
|
||||||
|
*$XDG\_RUNTIME\_DIR/foot.sock*, */tmp/foot.sock*.
|
||||||
|
|
||||||
|
## Variables set in the child process
|
||||||
|
|
||||||
|
*TERM*
|
||||||
|
terminfo/termcap identifier. This is used by client applications
|
||||||
|
to determine which capabilities a terminal supports. The value is
|
||||||
|
set according to either the *--term* command-line option or the
|
||||||
|
*term* config option in *foot.ini*(5).
|
||||||
|
|
||||||
|
*COLORTERM*
|
||||||
|
This variable is set to *truecolor*, to indicate to client
|
||||||
|
applications that 24-bit RGB colors are supported.
|
||||||
|
|
||||||
|
*PWD*
|
||||||
|
Current working directory (at the time of launching foot)
|
||||||
|
|
||||||
|
*SHELL*
|
||||||
|
Set to the launched shell, if the shell is valid (it is listed in
|
||||||
|
*/etc/shells*).
|
||||||
|
|
||||||
|
In addition to the variables listed above, custom environment
|
||||||
|
variables may be defined in *foot.ini*(5).
|
||||||
|
|
||||||
|
## Variables *unset* in the child process
|
||||||
|
|
||||||
|
*TERM_PROGRAM*
|
||||||
|
*TERM_PROGRAM_VERSION*
|
||||||
|
These environment variables are set by certain other terminal
|
||||||
|
emulators. We unset them, to prevent applications from
|
||||||
|
misdetecting foot.
|
||||||
|
|
||||||
|
In addition to the variables listed above, custom environment
|
||||||
|
variables to unset may be defined in *foot.ini*(5).
|
||||||
|
|
||||||
|
# Signals
|
||||||
|
|
||||||
|
The following signals have special meaning in footclient:
|
||||||
|
|
||||||
|
- SIGUSR1: switch to the dark color theme (*[colors-dark]*).
|
||||||
|
- SIGUSR2: switch to the light color theme (*[colors-light]*).
|
||||||
|
|
||||||
|
When sending SIGUSR1/SIGUSR2 to a footclient instance, the theme is
|
||||||
|
changed in that instance only. This is different from when you send
|
||||||
|
SIGUSR1/SIGUSR2 to the server process, where all instances change the
|
||||||
|
theme.
|
||||||
|
|
||||||
|
Note: for obvious reasons, this is not supported when footclient is
|
||||||
|
started with *--no-wait*.
|
||||||

* *which* sets of modifiers are needed to produce it, and compare

|
* with 'mods'.
|
||||||
|
*
|
||||||
|
* If there is at least one common modifier, it means 'sym' is a
|
||||||
|
* "shifted" symbol, with the corresponding shifting modifier
|
||||||
|
* explicitly included in the key combo. I.e. the key combo will
|
||||||
|
* never trigger.
|
||||||
|
*
|
||||||
|
* We then proceed and "repair" the key combo by replacing 'sym'
|
||||||
|
* with the corresponding unshifted symbol.
|
||||||
|
*
|
||||||
|
* To reduce the noise, we ignore all key codes where the shifted
|
||||||
|
* symbol is the same as the unshifted symbol.
