jekyll-pseudocode-b

A pseudocode/algorithm formatter for sites powered by Jekyll.

This is a updated fork from wkm/jekyll-pseudo.

Sometimes you don't want to use a particular programming language to demonstrate a concept because of the syntactic overhead. jekyll-pseudocode-b lets you use a gently styled free-formated representation.

Usage:

0. Install the gem

gem install jekyll-pseudocode-b

1. Add the following line to your site's Gemfile

gem 'jekyll-pseudocode-b'

2. And add the following line to your site plugin's _config.yml

plugins:
  - jekyll-pseudocode-b

Note: if jekyll --version is less than 3.5 use:

gems:
  - jekyll-pseudocode-b

Language

• Indentation is preserved
• A word beginning with a capital letter is a keyword
• A word followed by parentheses is a function name
• All other words are variables
• Words within double or single quotes are generally strings
• Variables that calls a function can reproduce the following output: myVar.FUNCTION(a);
• A word that starts with @ will be marked as 'special'. This is if you want to highlight a variable.

Output

Output is annotated with <span> classes and can be styled using CSS. Typically keywords are made bold and variables are italicized. Using the following code lines:

{% pseudocode %}
Function swap(old, new)
  remaining <- quorumSize
  success <- False
  For Each host
    result[host] <- send(host, propose(old, new))
    If result[host] = "ok"
      remaining--

  If remaining > 1+quorumSize/2
    success <- True

  For Each result
    If success
      send(host, confirm(old, new))
    Else
      send(host, cancel(old, new))
{% endpseudocode %}

With a bit of formatting, the above code becomes:
