To add new proposals, open a new issue, describe what and why we should change. Add an example as well as explain the use case to archive.

How to use

  • Don't use it.

But if you really insist:

uff.uff

should should be <<be>>
be should be <<should>>
say be should
the answer is 0
~> uff build uff.uff
~> bin/uff
should be

Grammar

exit_statement = "the" whitespace "answer" whitespace "is" whitespace ( integer | identifier ) .
assign_statement = identifier whitespace "should be" whitespace expression .
expression = ( integer | identifier | string | decimal_float ) .
string = "<<" /* any character */ ">>" .
identifier = (unicode_symobls | unicode_letter) { unicode_symobls | unicode_letter | unicode_digit } .
imaginary = ( decimal_float | integer ) "i" .
decimal_float = integer "." digits [ "e" integer ] .
integer = [ "-" ] digits .
digits = digit { ["_"] digit } .
digit = 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 .
whitespace = whitespace_character { whitespace_character } .
whitespace_character = /* Unicode 13.0.0 Character Class: White_Space */ .
unicode_symobls = /* Unicode 13.0.0 Character Classes: Sm, Sc, Sk, So */ .
unicode_digit = /* Unicode 13.0.0 Characer Class: Nd */ | "_" .
unicode_letter = /* Unicode 13.0.0 Characer Classes: Lu, Ll, Lt, Lm, Lo */.

Assign

  • should be

Comments [Proposal]

  • ': Block comment
  • ": Line comment

Exiting

To exit the program just use the keyword: the answer is <int64>. If no explicit exit code was given, 42 is used.

Datatypes

Strings

Strings have to begin with << and end with >>. The use of >> in the string is not possible.

complex128

2x float64, split up in imaginary and real part.

float64

int64

bigint

array[generic]

  • Access: b@2 or b@-2 -- Not so sure about this syntax

struct

This may be a valid struct in uff. This is also subject to be discussed.

bla struct {
    " This is a line comment
    pub {
       message string
       success bool
       data object
    }
}

Exceptions

Exceptions are named heart attacks.

Pointer

Generics

tbd as keyword

CAT Mode

The CAT mode is enabled by default. The program behaves like a cat. It has multiple lifes.

How many lifes your program has, depends on the target architecture.

Required keywords

These should be valid keywords, but I don't have an idea, what to use them for:

  • xd
  • uff
  • yeet
