TWOONENINE-Lang

Assembly-like language interpreter

About and Intention

TWOONENINE-Lang is an assembly-like language. The intention is to make it easier to write in an "assembly-like" way, with some higher level constructions possible, such as Data Structures. I may write a compiler for this language later on to achieve a later intention. I may also add "time calculating" capabilities baked into the instruction set. The intention of this language is to be a simple language that is easily understood. The later intention that may become evident, is for this language to be possible to use for writing algorithms and testing them experimentally, without the overhead of "JIT Compilers" or "Interpretation".

Architecture

TWOONENINE-Lang is intended to be an assembly-like language that makes implementing data-structures easier. The following is the architecture:

NODEs can locally store their own Data and have their own local accumulator. They can also be used to pass data to other NODEs.

dat0-dat15 can store integers or strings.

acc can store integers or strings. All subtraction, and conditional logic operates on the value in the accumulator

InstructionSet

• NODE number - Create a NODE. Currently, only NODE 0 does anything, and operates as where the code is run from.
• LABEL labelName - Create a LABEL. LabelNames must be fully connected names without spacing.
• SUB number - Subtract a number from the Accumulator.
• MOV register number - Move a number into a register.
• MOV register register - Move the contents of a register to another register.
• MOV register str string - Move a single fully connected String into the register.
• MOV register inp - Move contents from user input into the Register. USER INPUT MUST BE INTEGERS.
• MOV register out - Output the contents of Register to the screen.
• JGZ labelName - Move from current line to the line at the label corresponding with that labelname if acc > 0.
• JEZ labelName - Move from current line to the line at the label corresponding with that labelname if acc == 0.
• JLZ labelName - Move from current line to the line at the label corresponding with that labelname if acc < 0.

Syntax rules

• All instruction names MUST be fully capitalised. No mov or mOv.
• All register names MUST be lower case. No Dat0 or DAT4.
• No indentation.
• Commenting and empty lines is fine.
• Commenting can be done by just writing, though it is recommended to prefix all comments with # .

Contributing

I encourage contribution. Feel free to write a compiler or interpreter for this language, or modify the language to have more instructions or syntax rules. License: MIT License
