Realy Strange Code

hi. i am new here. i get one code but i realy dont know which programming language is used.
the code:

d::=labrit!
a::=vakuums
t::=lolzors
u::=king
v::=0
e::=-3
:::===
)::=(
?::=.
a::=@
.::=:::
i::=-
@::=<|:|>
::=
asm.lv

Code (markup):

if someone can tell or compile this code i will be glad

p.s. sorry for bad english

 

no one knows?

 

If that was common code, it should return any results in Google. Seems like it doesn't...

http://www.google.com/search?q=a::=vakuums
http://www.google.com/search?q=d::=labrit

 

see, the words after 'a::=', 'd::=', 't::=' etc are simple words in Latvian (language of Latvia, thats were i'm living )

 

It's looks like some Backus-Naur Form (BNF) definitions.

BNF is a description method used to define language syntax for compilers.

In other words, it's a language for building languages. You can read more about BNF at wikipedia: http://en.wikipedia.org/wiki/Backus-Naur_form

For practical examples, pick up any book on compiler/parser/language design. The classic text in the field is the "dragon" book. It too has a wikipedia entry: http://en.wikipedia.org/wiki/Compilers:_Principles,_Techniques,_and_Tools

 

Pascal declarations are like A:=B but maybe its like in PHP when you can have VarVars? $$ = :: maybe? (Just my 2 centz)

 

ouh, at last i found it. its Thue. realy old programming language and the compilator for win32 is not working at all...
