The main language of this project is still Bau.
This here is an experimental language.
- Minimalistic syntax. Tiny footprint (~450 lines of code).
- Operator overloading is supported.
- Ability to minify the code. Each keyword has a single-character shortcut:
? if, : else, * repeat,
@ while, + fun, ! return,
> print.
This is also useful for code golfing,
and writing programs on the command line, or on a phone.
- Assignment is
:, and = is comparison.
- Global variables and constants start with a capital letter.
- Text literals start and end with
'.
As in SQL, the only escape character is '' for '.
Use free-standing text literals as comments.
- Commas and semicolons are optional.
& and | are logical and bitwise "and" and "or".- The only data type is: arrays of floating point values.
- Array indexing uses
.: a.0, a.1, a.2
- Zero error philosophy: out-of-bounds array access returns 0,
except for entry -1 which returns the length.
- Text has at least two elements (zero values are ignored).
