    Is OSX only?

    1. 3

      In principle the script is portable. The very first commit shelled out to run stty, but now the terminal is configured by the standard Ruby (1.9) library io/console.

        This is a total hack. It is procedural, uses a global variable, it has not been parametrized or generalized in any way. It was tailor-made for what I exactly wanted but some people in the audience asked for the script. Even if it is quick and dirty I am very happy to share it so I have commented the source code and there you go!

        I don’t see anything super OSX specific, but what I mean is that it might be, since that’s what computer fxn was using.

          I was partly wondering because if it was then a tag of “osx” would be handy. Anyways, i’d have look at this more closely to see if it’s usable in some form on ubuntu bash in gnome-terminal.

        Very cute. Interesting to see that even with the advent of GUIs and pretty graphics, some prefer to go “back in time” to terminals.

        1. 1

          Couldn’t get it to run because of some problems building the dependencies (for which I do not fault the author at all, mind you, given that it’s a total hack).

          However, it seems like much more work to build this than it is to just write those text files in a normal editor and export code to html. Here’s how to do it in vim:

          :TOhtml
          

          To be fair, that method is flawed because it just creates a single HTML file, which is not the same as a slideshow.

          Another alternative is to export code to RTF and just paste that in Keynote or Powerpoint or Impress. You can do this using highlight[0]. Here’s an example that works on a mac, (change pbcopy to xclip if you’re on linux; also note that you can easily do this on a text selection from inside of vim):

          cat codes.scala | highlight -S scala -O rtf -k Menlo -K 20 | pbcopy
          

          If that’s still too much, check out pandoc[1], which can convert a markdown file into a Slidy slideshow[2] (or S5, or some others, though I prefer the minimalist style of Slidy).

          pandoc -t slidy -s slideshow.md -o slideshow.html
          

          One issue with this is that you just get very basic code formatting. No problem, just add highlight.js[3] to the generated html file. It supports 52 languages out of the box, will guess the language in the <code> block, and will highlight them automatically (yes, you can specify the language if necessary).

          <script>hljs.initHighlightingOnLoad();</script>

            I have documented installation instructions now. Thanks!
