Whitespace Programs
A series of programs written in Whitespace. Also see my Whitespace compiler.
Structure
assemble.pysupports assembling a basic Whitespace assembly language into the actual Whitespace characters.asm/contains whitespace-assembly versions of the programs.ws/contains the Whitespace equivalents of the programs.
Assembly Language
The assembly language supports one command per line. The 24 basic commands are
| Command name | Type | Arguments (empty if none) |
|---|---|---|
| rchar | I/O | |
| rnum | I/O | |
| wchar | I/O | |
| wnum | I/O | |
| push | Stack | integer |
| dup | Stack | |
| swap | Stack | |
| pop | Stack | |
| copy | Stack | integer |
| slide | Stack | integer |
| add | Arithmetic | |
| sub | Arithmetic | |
| mul | Arithmetic | |
| div | Arithmetic | |
| mod | Arithmetic | |
| call | Flow | label |
| jump | Flow | label |
| jz | Flow | label |
| jn | Flow | label |
| ret | Flow | |
| end | Flow | |
| store | Heap | |
| load | Heap |
Arguments should be preceded by at least one space.
Labels
Labels can be made by ending a line with a :. To refer to a label as an argument, enter the part of the line before the :.
Numbers
Numbers can be written either in decimal (e.g., 10, 123, etc...) or as a character constant (e.g., 'a', "B", '\n', or "\t").
Commenting
; can be used for commenting--all characters starting at the ; and going to the end of the line will be ignored
Other Miscellaneous Notes
Except for at least one space separating arguments and instructions being separated by newlines, (ironically) white space is ignored.
