jekyll-pseudo

A pseudocode/algorithm formatter for sites powered by jekyll.

Sometimes you don’t want to use a particular programming language to
demonstrate a concept because of the syntactic overhead. Jekyll-Pseudo lets
you use a gently styled free-formated representation.

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 quotes are generally strings

• these symbols are auto-formatted: <-- <= >= --> =

Sample output:

{% pseudo %}
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))
{% endpseudo %}

Output

Output is annotated with <span> classes and can be styled using CSS. Typically keywords are made bold and variables are italicized.

With a bit of formatting, the above code becomes:
