4.1 – Lexical Conventions

Evi is free-from, meaning that spaces and comments are ignored, except in strings, in characters and as delimiters between tokens. Spaces are recognized as whitespaces, carriage returns and tabs. Only ASCII characters are accepted.

Identifiers consist of a series of alphanumeric characters or underscores, not starting with a digit. Evi has no alphanumerical keywords, so no identifiers are reserved by the compiler. Next to that, Evi is case-sensitive. meaning that mystring and myString are two different identifiers.

The following characters are reserved for keysymbols, operators and other tokens:

  (  )  {  }  [  ] 

  +  -  *  /  !  , 

  @  %  =  ~  ;  $
