Fuzzy find Rails migrations

Run rails migration commands via aliases with auto-completion for version numbers (via fzf)

brew install fzf
curl https://gist.githubusercontent.com/matthutchinson/6c1bc7681b323d4d2ef5d5a55626a5cf/raw > ~/.fzf_migrations
source ~/.fzf_migrations

Then run these commands to migrate:

rdbm  # bundle exec rake db:migrate (no auto-completion)
rdbmu # bundle exec rake db:migrate:up
rdbmd # bundle exec rake db:migrate:down
rdbmr # bundle exec rake db:migrate:redo

I have other useful fuzzy find helpers here (for git, bash etc.)

You can download this recording in asciicast v2 format, as a .cast file.

Download

Replay in terminal

You can replay the downloaded recording in your terminal using the asciinema play command:

asciinema play 180507.cast

If you don't have asciinema CLI installed then see installation instructions.

Use with stand-alone player on your website

Download asciinema player from the releases page (you only need .js and .css file), then use it like this:

<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" type="text/css" href="asciinema-player.css" />
</head>
<body>
  <div id="player"></div>
  <script src="asciinema-player.min.js"></script>
  <script>
    AsciinemaPlayer.create(
      '/assets/180507.cast',
      document.getElementById('player'),
      { cols: 235, rows: 65 }
    );
  </script>
</body>
</html>

See asciinema player quick-start guide for full usage instructions.

While this site doesn't provide GIF conversion at the moment, you can still do it yourself with the help of asciinema GIF generator utility - agg.

Once you have it installed, generate a GIF with the following command:

agg https://asciinema.org/a/180507 demo.gif

Or, if you already downloaded the recording file:

agg demo.cast demo.gif

Check agg --help for all available options. You can change font family and size, select color theme, adjust speed and more.

See agg manual for full usage instructions.
