.Os Telodendria Project
.Sh NAME
.Nm Telodendria
.Nd The terminal branches of an axon.
.Sh DESCRIPTION
.Nm
is an open source Matrix homeserver written entirely from scratch in ANSI C and
designed to be lightweight and simple, yet functional.
.Pp
.Sy Note:
.Nm
is under
.Sy heavy
development. Please see
.Sx PROJECT STATUS .
.Pp
.Nm
differentiates itself from the other Matrix homeserver
implementations because it:
.Bl -bullet
.It
Is written in C, a stable, low-level programming language with a
long history, low build and runtime overhead, and wide compatibility.
.It
Is written with minimalism as a primary design goal. Whenever possible
and practical, no third-party libraries are pulled into the source code.
Everything
.Nm
needs is custom written. As a result,
.Nm
depends only on a standard C compiler and a POSIX C library to be built,
both of which should come with any good Unix-style operating system already,
which means you shouldn't have to install anything extra.
.It
Uses a flat-file directory structure to store data instead of a database.
This has a number of advantages:
.Bl -bullet
.It
It makes setup and maintenance much easier.
.It
It allows
.Nm
to run on systems with fewer resources.
.El
.It
Is packaged as a single small, statically-linked and highly-optimized binary
that can be run just about anywhere. It is designed to be extremely easy to
set up and consume as few resources as possible.
.It
Is permissively licensed.
.Nm
is licensed under a modified MIT license, which imposes very few restrictions
on what you can do with it.

.Nm
is designed to be fairly straightforward, but that doesn't mean there
won't be hiccups along the way. If you're struggling to get
.Nm
up and running, you're more than welcome to reach out for support. Just
hop into the appropriate Matrix rooms and talk to me!
.Sh RATIONALE
I want a lightweight Matrix homeserver designed specifically for OpenBSD,
and other Unix-like operating systems. I want a homeserver that can be
developed and compiled with built-in tools. I want it to function entirely
on a base OS install without having to install any packages whatsoever. I've
found that as far as these goals are concerned, the existing homeserver
implementations fall short. This project aims to prove that Matrix homeservers
can be lightweight and written in such a way that very few, if any, third-party
libraries need to be pulled in.
.Pp
I also want to learn how Matrix works, and I want to understand the code I'm
running on my server, which is why I'm writing every component from scratch,
even the HTTP server and router.
.Pp
The advantage of using a flat-file database instead of a real database is that
your data remains in a format that is incredibly easy to digest. Backups are
incredibly easy as well\(emjust
.Xr tar 1
up the data directory and you're good to go.
.Sh PROJECT GOALS
The goals of this project are generally divided into user goals and developer
goals, depending on who they impact the most. This isn't an exaustive list
of the project's goals, but it is a list of things that I want to prioritize,
because other server implementations lack them.
.Pp
The user goals are as follows:
.Bl -bullet
.It
To implement the latest Matrix specification as fully and completely as possible.
All features defined by the specification should eventually be present in
.Nm .
.It
To be as privacy-friendly as possible.
.Nm
should not store any information it does not absolutely need to function as a
Matrix homeserver. While
.Nm
strives to be feature-complete, it should not implement anything not explicitly
defined in the Matrix specification.
.It
To be a production-ready Matrix server capable of working in constrained environments,
such as embedded devices, cheap VPSs, or a peer-to-peer device.
.Nm
should also work on traditional setups as well, and be able to handle a decent
amount of users. It should work well for personal Matrix homeservers that also
host a few friends and/or family members.
.It
To be easier to get up and running, and yet also be more configurable than other
Matrix homeserver implementations. The configuration file should be flexible,
well-documented, and easy to understand and modify. An intuitive command-line
tool for administrative tasks should also be available.
.El
.Pp
The developer goals are as follows:
.Bl -bullet
.It
To have as few build and runtime dependencies as possible. It should be possible
to compile and run
.Nm
on any POSIX operating system right out of the box. 
.Nm
should be fully statically-linked, so it can run under a
.Xr chroot 3 .
Furthermore, it should be possible to read all the documentation offline, and
without any overly complicated tools. You'll notice that this documentation is
a collection of
.Xr man 1
pages, not HTML or Markdown, to remove the dependency on a browser or Markdown
parser. Any Unix-like system has a manual page viewer, which makes the
documentation more accessible, even on remote systems that have no graphical
interface to read the documentation. This ensures that you can read the
documentation for the installed version of
.Nm
without having to go online.
.It
To have a simple yet elegant workflow, and not depend on any large or complex
development tools such as code forges. The entire development workflow should
be able to be successfully and efficiently completed on a base OpenBSD install.
Of course, you don't have to use OpenBSD for development, but the point is that
the workflow should require fairly standardized and simple tools.
.It
To write clean, elegant, well-tested, and well-documented code. The goal is to build
a Matrix homeserver from the ground up, not just because I don't like the way existing
homeservers are implemented, but also because I want to learn how Matrix works,
make it more accessible, and potentially teach others a little bit along the way.
.It
To foster a welcoming community. Many big communities such as Linux and OpenBSD
have hostile leaders.
.Nm
shouldn't have a hostile leader. I want to be as understanding as I can, and talk
through issues politely and in a civil manner. If I'm failing in this way, don't
be afraid to call me out!
.El
.Sh PROJECT STATUS
Telodendria is a very ambitious project. There's a lot that needs to happen yet
before it is usable. At the moment, there's nothing here that even remotely resembles
a Matrix homeserver. I'm still getting off the ground and building a foundation.
.Pp
But just because there's nothing here yet doesn't mean you should go away! I could
always use help, so you are more than welcome to help out if you want things to go
quicker. Please see the
.Xr contributing 7
page for details on how you can get involved. The CVS repository has a file called
.Pa TODO.txt ,
which contains a checklist of what has been done so far, and what's on the radar
to be done. You can take a look at it once you've checked out the source code.
If you'd like to help out, feel free to grab an item on the list that's not done
yet and start getting patches written. When you're done, enjoy the satisfaction
of crossing the item off the list yourself.

.Sh STANDARDS
The installed version of
.Nm
conforms to the latest Matrix specification available at the time
of its release.
.Sh HISTORY
At this time,
.Nm
does not have any tagged releases because it is not yet functional
as a Matrix homeserver. Please checkout out
.Sx PROJECT STATUS
to see where things are currently at. When
.Nm
is mature enough to have a change log, it will go in this section.
