Brainf* interpreter in RegEx only (find/replace)



  • I’ve written a Brainf* interpreter in RegEx. All you need to do is add the source code in Brainf* on the first line of a new document and use the following parameters in find/replace (click “replace all” until it doesn’t find any matches). Documentation here

    Find:
    (?<PLUS>*+(?<PL_SK1>[\w\W]?@[)(?<PL_VAL>[0-9A-F]{2})(?<PL_SK2>][\w\W]?{\k<PL_VAL>[\w\W]}{)(?<PL_INC>[0-9A-F]{2}))|(?<MINUS>*-(?<MI_SK1>[\w\W]?@[)(?<MI_VAL>[0-9A-F]{2})(?<MI_SK2>][\w\W]?{)(?<MI_DEC>[0-9A-F]{2})(?<MI_SK3>[\w\W]}{\k<MI_VAL>))|(?<LEFT>#@)|(?<RIGHT>@#)|(?<GREATER>(?<GR_OP>*>)(?<GR_SK1>[\w\W]?#[\w\W]?)@(?<GR_CE>[[0-9A-F]{2}]))|(?<LESS>(?<LE_OP>*<)(?<LE_SK1>[\w\W]?#[\w\W]?)(?<LE_CE>[[0-9A-F]{2}])@)|(?<OPENZ>*(?<OZ_OUT>[(?<OZ_IN>[^[]]|(?-2))])(?<OZ_SK1>[\w\W]?@[00]))|(?<OPENN>*(?<ON_OUT>[(?<ON_IN>[^[]]|(?-2))])(?<ON_SK1>[\w\W]?@[(?!00)))|(?<FORWARD>’[)|(?<CLOSE>*])|(?<BACK>(?<BA_OUT>[(?<BA_IN>[^[]]|(?-2))])")|(?<POINT>:(?<PO_SK1>[\w\W])*.(?<PO_SK2>[\w\W]@[)(?<PO_VAL>[0-9A-F]{2})(?<PO_SK3>][\w\W]{\k<PO_VAL>)(?<PO_CHAR>[\w\W]))|(?<COMMA>|(?<CO_IN>[\w\W])(?<CO_SK1>[\w\W]?)*,(?<CO_SK2>[\w\W]?@[)[0-9A-F]{2}(?<CO_SK3>][\w\W]?{)(?<CO_VAL>[0-9A-F]{2})\k<CO_IN>)|(?<INIT>(?<IN_CD>^[+-<>[].,]+$))|(?<HALT>(?<HA_RM>:[\w\W]?*&[\w\W]*$))
