Hi Patrick, I am now working on a rewrite of the texshow perl script, and we still have to come up with an interface for the interface between the perl script and web version. For the immediate (and not so immediate) future, this will be just queries from texshow to the web using a GET url, I have no plans for an editting interface in the script (for now). How do you feel about this URL convention: <cgi>?interface=<interface>&previous=<unixtime> <cgi> == http://texshow.contextgarden.net/query.cgi <interface> == cont-en OR cont-nl OR .. <unixtime> == unix timestamp of the previous query from this particular instance of texshow And then the CGI returns an XML snippet containing all of the changed command definitions. Is that acceptable and doable? Greetings, Taco
