Configuring /opt/local/ and /opt/local/dev

In a unix system /opt/ is for optional software, it’s not like your /Application folder on a Mac necessarily.

As pr example below

/opt/local/<<MyDAM>>/
/opt/local/bin/<<MyEXIFtool>>
/opt/local/dev/<<MyEXIFtool>>/
/opt/local/dev/<<MyDAM>>/
/opt/local/dev/swift/

Wheres /opt/local/dev/swift is downloaded from GitHub

cd /opt/local/dev
git clone https://github.com/apple/swift

Note that while /opt/local/dev holds the source code, /opt/local/<<projectname>> holds a larger project or installation, while /opt/local/bin holds single binaries such as ls

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

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/295210.cast',
      document.getElementById('player'),
      { cols: 118, rows: 34 }
    );
  </script>
</body>
</html>

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

While this site doesn't offer 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 run the following command to create GIF file:

agg https://asciinema.org/a/295210 295210.gif

Or, if you already downloaded the recording file:

agg 295210.cast 295210.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.
