Twit-arr is a micro-blogging site that is set up for JoCo Cruise. Originally developed by walkeriniraq. This version is no longer in active development, but is being kept around as a fallback. Development on the new version is currently taking place here: https://github.com/jocosocial/swiftarr/

Twit-arr was the name for the Status.net instance brought onto the cruise ship for JCCC2 and JCCC3. Status.net being less than optimal for this environment, I took it upon myself to build a new version, completely customized for the cruise.

If you're not running on linux, or just want an isolated environment, you can run twitarr in docker.

You'll need the Docker toolbox. I (Joey) used version 1.16.1. The default install on a Mac is Just Fine; not sure about other platforms.

• Create a default_users.yml file based on the default_users.yml.example file. Set the reg codes to alphanumeric strings (all uppercase). Pick strong passwords of your choice.
• Create a master.key file adjacent to secrets.yml (in the /config directory) containing a sufficiently long random hex string. Consider using rails secret to generate.
• If you want to run with local changes (so that you can change the Ruby code and not have to rebuild the world each time), modify docker-compose accordingly:

  volumes:   # Remove this for production use
   - ./:/srv/app

Run:

   $ docker-compose build [--no-cache]
   $ docker-compose up
   # When you're done
   $ docker-compose down [-v]

This will create a docker image based on ruby, as well as download a postgres image.

This can take a while to set up, as it generates the database and seed data in postgres. Once it completes you should be able to reach twitarr via http://localhost:3000.

1. Install pre-reqs

   Debian 11:

   sudo apt-get install git gnupg2 curl imagemagick libmagickwand-dev libidn11-dev libpq-dev postgresql postgresql-contrib nodejs redis
   

   Fedora 34:

   sudo dnf install git gnupg2 curl imagemagick ImageMagick-devel libidn-devel libpq-devel postgresql postgresql-contrib nodejs redis
   

2. Set your postgres password

   Debian 11:

   sudo -u postgres psql
   \password
   Set the password to whatever you want. Simplest is `password`
   \q
   

3. Install RVM. Follow the instructions at https://rvm.io/. Reload your terminal environment after installing.

4. Clone the repository, cd into it

5. If pompted by RVM, install the required version of ruby, then leave and re-enter the directory to create the gemset

   rvm install ruby-3.1.0
   

6. Install gems

   bundle install
   

7. Copy the dev environment file. If you used a different postgres password, or need ot change the postgres connection info, edit the .env file after copying it:

   cp .env-example .env
   

   Also copy the default users file, and edit it. Set the reg codes to alphanumeric strings (all uppercase). Pick strong passwords of your choice:

   cp config/default_users.yml.example config/default_users.yml
   

8. Populate the database

   rails db:setup
   

9. Run the dev server

   rails server
   

The database population will create 20 reusable registration codes, which can be used for creating new users. The created codes are numbered, code1 through code20. Note that codes 1 through 4 will already be used by the default users.

For these default users, the user's password is the same as the username.

1. kvort (code1, an admin user)
2. james (code2, a non-admin user)
3. steve (code3, a non-admin user)
4. admin (code4, another admin user)

By default, the dev server can be hit from http://localhost:3000
