-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I'm trying to write a parser which can write on the input string (mainly insert string at the current position). Does spirit contain any stuff that can help me in that way ?

You're probably better off representing this as a transformation instead of an edit-in-place.

AFAIK, Spirit doesn't contain any mechanisms for modifying the input -- that's considered beyond the scope of a parser. You could probably create your own out-of-band mechanism for doing it, but it would probably mess up spirit's idea of where it is within the input as you modified the input. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download http://www.xmission.com/~legalize/book/download/index.html Legalize Adulthood! http://blogs.xmission.com/legalize/

You're probably better off representing this as a transformation instead of an edit-in-place. I'm afraid you're right but I wanted to avoid it.

You could probably create your own out-of-band mechanism for doing it, but it would probably mess up spirit's idea of where it is within the input as you modified the input. I haven't really thought but I guess I would need
* to maintain iterators during each input transformation, * perhaps to trigger some "cut" or backtrack. By the way, I was wondering if "multi_pass" could meet some of my requirements but I haven't found any example. Has someone seen an example illustrating multi_pass ?
