Are node positions available?

[bmewburn]

Hello, you've done some nice work here, thanks for your time on this! I wondered if the ast node and attribute positions were available? If not is this something planned or within scope of this parser?

Hi @bmewburn,

The lexer tracks the line, but not the column. Also, the resulting AST node does not provide any informations about location.

Of course this kind of feature would be a must have in this parser but actually I have no time in order to implement it.

If I would have to do it, I would start to calculate the column offset on the lexer first, and next I would implement a sort of function builder in order to build nodes.

This function will track the node start, and return a function. By calling the function later in order to retrieve the node instance, it would also track the node end, so I would provide a start position, and end position.

If you have time I would really grateful, but anyway, if you don't I think this would be part of a later release.

Best Regards,
Ioan
