urbit
urbit is a new programming and execution environment designed from scratch.
At present urbit is under heavy development. If you're interested in keeping in touch or following the project you can:
- Enter your email address at urbit.org.
- Subscribe to the urbit-dev mailing list.
- Follow @urbit_ on Twitter.
- Get in touch with us via email, urbit@urbit.org
All of the source code is distributed under the MIT license, but is for all intents and purposes in the public domain.
Install
urbit depends on:
gcc
gmp
libsigsegv
openssl
automake
autoconf
ragel
cmake
re2c
libtool
libssl-dev (Linux only)
ncurses (Linux only)
Ubuntu or Debian
sudo apt-get install libgmp3-dev libsigsegv-dev openssl libssl-dev libncurses5-dev git make exuberant-ctags automake autoconf libtool g++ ragel cmake re2c
Fedora
sudo yum install gcc gcc-c++ git gmp-devel openssl-devel openssl ncurses-devel libsigsegv-devel ctags automake autoconf libtool cmake re2c
AWS
sudo yum --enablerepo epel install gcc gcc-c++ git gmp-devel openssl-devel ncurses-devel libsigsegv-devel ctags automake autoconf libtool cmake re2c
OS X - Homebrew
brew install git gmp libsigsegv openssl libtool autoconf automake cmake
OS X - Macports
sudo port install git gmp libsigsegv openssl autoconf automake cmake
Although automake/autoconf/libtool are generally installed by
default, some have reported needing to uninstall and reinstall those
three packages, at least with Homebrew. Your mileage may vary.
Build
Clone the repo:
git clone git://github.com/urbit/urbit.git
cd to the directory you just created:
cd urbit
Just run make:
make
Run
Inside of the urbit directory run
bin/urbit -c pier
where pier is a directory that does not exist.
All your state (an append-only log and a memory checkpoint) will live in this directory. The name of your pier doesn't matter and is not visible internally.
Begin
To begin a 32-bit planet use
:?begin
which will guide you through the setup process.
Basics
^v will switch between the task manager and the focussed process. ^x
will switch between processes.
To start a process that is not yet started run *proc from the task
manager.
^d will exit the pier from the task manager. No matter how you shut
your urbit down you'll be returned to exactly the same state as when you
turned it off.
Talk
If talk is not running, start it with *talk from the task manager.
Use ^x to switch to the talk prompt and then run
;join ~doznec/urbit-meta
to join the urbit-meta channel. People in there are helpful.
There are four main talk commands:
;join ~urbit-name/channel
;join subscribes your main feed to a remote channel.
;create channel %name 'description'
;create creates a channel on your urbit.
;<number>
;<number> activates a previous message number, like a URL that got
clipped.
;<target>
;<target> sets the target for your messages, such as ;~urbit-name
for a private message.
Sysadmin
For the most part, updates to the system are automatically synced to your urbit across the network.
When we make updates to the interpreter you should be able to shut down your urbit and:
git pull origin master
make
bin/urbit pier
where pier is the name of your pier.
While the network is still young from time to time we reboot the entire thing. We call this a 'continuity breach' since we're breaking the continuity of our crypto.
When this happens you'll need to back up your data and start a fresh pier. Your original ticket will still work.
