fwg / s-expression Goto Github PK

How to make the same behaviour for " and '.
In my case I need " и ' to be parsed into String objects

 $ node
> s = require("s-expression")
> new s("(\"a a\")")
[ '"a', 'a"' ]

Should produce ['"a a"']

S = require('s-expression');

console.log(new S("(\"a)"));

This prints ['"a'], when I would expect it to be a parse error because the string literal is unterminated.

Support for comments would be a nice addition.

Common lisp, scheme and clojure all use semicolon as a single line comment character:

(1 ; this is ignored
2 3)

Everything from the semicolon to the end of the line is ignored.

There's also a less used block comment convention that looks like #|... |#

Thanks!

The parser appears to stop as soon as it finds a valid s-expression, and doesn't continue to the end of the string to find potential errors. So, for example

Parse = require('s-expression');
console.log(new Parse("())"));

Will result in the s-expression [], when I would expect it to give an error. Same early termination behavior for e.g. ()abc or ((a) b)), which I would also expect to be errors.

Is it possible the same behaviour for different type of brackets?

For example (a b (c [d e]))
