The following outlines the LOLCODE specification that this parser uses.

LOLCODE Recommendation v1.0 + modifications

• Statements are separated by [\n.]+
• CAN HAS <module/"file">?
  • for inclusion/requirement
• GIMMEH [(LINE|WORD|LETTAR)] [OUTTA ]
  • with default being LINE and STDIN
• HAI
• KTHXBYE
  • only closes HAI and exits with good condition
• DIAF [ []]
  • Exits the program (failure)
  • Status code:
  • Printed to stderr or equivalent:
• BYES [ []]
• KTHX
  • is the universal "closing bracket" line
  • for any if block, looping block, function, etc... except HAI
• IM IN YR []
  • label has no effect
• VISIBLE [!]
  • prints stuff as minimally as possible and with a newline (unless !)
• I HAS A [ITZ ] Declare a variable. Auto-recognize the type among:
  • NUMBAR (integer, currently)
  • YARN (string)
  • TROOF (boolean)
  • BUKKIT (array)
• MAH !!
  • indexes into the array
  • Multiple occurences of this index sub-levels of the array.
    • 1 IN MAH 2 IN MAH arr <=> arr[2][1]
  • Does NOT expand the size of the array (except as l_value of assignment)
    • Throws error/dies on out of bounds?
• LOL R
  • Assigns value into l_value specified by var.
  • Extends the size of var if necessary
  • If no index is specified, applies to all elements? (one by default)
• IZ [?] [(.|\n) YARLY] (.|\n) (.|\n) [NOWAI (.|\n) ] KTHX
  • Conditional syntax. See examples.
• Operators are PREFIX. Everything but NOT is binary.
• Logical/Bitwise operators: (NOT|AND|OR|XOR)
  • NOT OR AN
  • XOR AN
• Comparison operators: (BIGR|SMALR|LIEK) ( [DEN|AN] )
  • NOT BIGR DEN
  • LIEK AN
• BTW
  • Comment syntax. Runs until end of line. Only valid on its own line.
