These lines begin :: :: with "::". :: :: :: :: File Notes :: :: File notes are the remaining lines when all other :: :: information is removed from the file header, e.g., :: :: raw file notes and macros. :: :: :: :: As an example, file notes can contain general :: :: properties written as key/value pairs, such as :: :: "Author: Name". :: :: :: :: The optional but recommended property :: :: "Collection: Name" assigns a name to the puzzle :: :: collection. When a collection is copied from a :: :: website or e-mail and pasted into a Sokoban program, :: :: this information allows the collection to be saved :: :: with the proper name. :: :: :: :: Game Type :: :: The type applies to all levels in the file. If it is :: :: not specified, the default value is "Sokoban". :: :: :: :: The type is written as "Game: X" or "Game=X". :: :: An example: "Game: Hexoban". :: :: :: :: Macros :: :: Macros are key/value pairs separated by "=". :: :: An example: "Copyright=These levels are (c) by NN". :: :: :: :: The value of a key/value pair can be inserted in :: :: level notes and game notes by writing the key :: :: enclosed by "<#" ... "#/>". This applies to both :: :: types of key/value pairs, ":" and "=", but in :: :: contrast to ":" pairs, macros are not considered :: :: a part of the file notes. :: :: :: :: An example of macro usage: "<#Copyright#/>". :: :: The use of key/value pairs is case-insensitive. :: :: :: :: Macro-definitions are single-lined. To insert a :: :: line-break in the expanded text, write "\n". :: :: :: :: Titles :: :: A title line is the last non-blank text line before :: :: a level or a game, provided the line is preceded :: :: by a blank line or it is the only text line at this :: :: position in the file. :: :: :: :: Title lines are optional unless a single or a last :: :: text line from a preceding level, game, or file :: :: header can be mistaken for a title line. :: :: :: :: Level Notes :: :: Two special key/value pairs are supported in level :: :: notes: "Title" and "Author", hence, titles can :: :: either come from a title line or from a key/value :: :: pair. :: :: :: ::::::::::::::::::::::::::: Board :::::::::::::::::::::::::: :: Legend.................: :.................Legend :: :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: :: Wall...................: # # :...................Wall :: :: Pusher.................: @ p :.................Pusher :: :: Pusher on goal square..: + P :..Pusher on goal square :: :: Box....................: $ b :....................Box :: :: Box on goal square.....: * B :.....Box on goal square :: :: Goal square............: . o :............Goal square :: :: Floor..................: :..................Floor :: :: Floor..................: - _ :..................Floor :: :: :: :: Remarks: :: :: :: :: The first and the last non-empty square in each row :: :: must be a wall or a box on a goal. A board cannot :: :: have empty rows. :: :: :: :: Boards may be run-length encoded (RLE), e.g., :: :: "###----@.#" may be encoded as "3#4-@.#", and :: :: "#-#-#-##-#-#-#" may be encoded as "2(3(#-)#)". :: :: A row cannot be split over multiple physical lines. :: :: :: :: Rows may be combined on a single physical line by :: :: using "|" as a row separator, e.g., :: :: "--3#|3#-#|#@$.#|5#". A "|" at the end of a physical :: :: line is optional and may be omitted. :: :: :: ::::::::::::::::::::::::::: Moves :::::::::::::::::::::::::: :: Legend.................: :.................Legend :: :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: :: Move pusher up.........: u U :.......Push/pull box up :: :: Move pusher down.......: d D :.....Push/pull box down :: :: Move pusher left.......: l L :.....Push/pull box left :: :: Move pusher right......: r R :....Push/pull box right :: :: Jump start.............: [ ] :...............Jump end :: :: Current position.......: * * :.......Current position :: :: :: :: Remarks: :: :: :: :: Moves may be run-length encoded, e.g., "3r3U" means :: :: "rrrUU", and "2(3(dr)R)" means "drdrdrRdrdrdrR". :: :: Each line must, however, have at least one proper :: :: non-digit character. Spaces between moves are :: :: allowed. :: :: :: :: Jumps and pulls: Only in reverse mode games. :: :: :: :: Reverse mode games must start with a jump, even if :: :: it is empty. An example: "[]UU[ddlll]DDllR". :: :: :: :: Current position is optional and defaults to the :: :: position after the last move. :: :: :: :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: Date Created: Date of Last Change: 2010-01-26 17:44:01 :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: Macros The macro feature allows levels to share a common text such as a copyright notice. An example: Copyright=Copyright (c) 3642 by xyz@paris.mars Demo Level 01 ######## # # #@ $ # # $ # # . . # ######## This demo level is trivial, but it suffices to demonstrate the file-format. A Sokoban program can add key/value pairs within the notes, such as: Author: nn Website: http://www.nn.net Solution/Moves (rurrdD)(uLulDD) The title of a snapshot does not bear any special meaning. This snapshot just happens to be the best solution found (so far). The demo-program automatically saves best solutions. Snapshot 7/0 urrrrdd This is an example of a snapshot saved by the user. Later he/she can continue work on this path. Snapshot 9/2 urrrrddLL*ruulDD Another snapshot saved by the user. The '*' indicates current position, i.e., the last moves were taken back, but are still available for the "redo" function. Demo Level 02 ######## # .# #@ $ # # $ # # . * # ######## Just another trivial demo level. The number of levels in a file is limited by available memory only. A macro example, inserting the text defined in the copyright-macro: <#Copyright#/> Solution/Moves (rRRR)(drU)(dlLLulD) Reverse Mode Snapshot 13/6 [rrrd]UU(rLLL)(drD) This is an example of a reverse mode snapshot. Reverse mode snapshots always have a leading jump-sequence, even if it is empty. An example: "[]Ulld...". Demo Level 03 ######## # # # $ # # $ # # + . # ######## Solution/Moves (rrruul)(Lr)(Duull)(DD)
