project specifics

This package contains a version of S-expression parser written in Javascript. Beside ordinary S-expression support, it features peculiar style comments and indent sensitive multi-line strings. Shortly, we expose all of its main features by the following example:

///
this is a
multi-line
comment
///

(
    atom
    
    (
        /this is a comment/
        this is a list
        (
            /one more comment/ one more list /also a comment/
        )
    )
    
    "this is a unicode string \u2717 \u2714"
    
    (more atoms)
    
    """
    this is a
    multi-line
    string
    """
)
