Language Reference

Modules

A yagbas source file is called a "module".

Tokens

Source code has to be tokenized first during compilation. This breaks it up into punctuation, keywords, identifiers, and so on.

• Identifiers: These start with an ASCII letter or an underscore, and can then contain any number of ASCII letters, underscores, and digits. Identifiers can't be any language keyword.
• Numbers: Numbers can be in decimal, binary (with a leading %), or hexadecimal (with a leading $). Numbers can contain underscore characters for easier reading, this doesn't affect the value.
• Line Comments: Line comments start with // and go to the end of the line.

Token Trees

Tokens are grouped into "trees" with pairs of opening and closing markers.

• Parens: ( and )
• Braces: { and }
• Brackets: [ and ]
• Block Comments: /* and */

The opening and closing markers for each token tree group must match, or the source file cannot be processed.
