We should improve the API, indeed. Would you be interested in working on that? Extra bonus points if we can write a simple "`request` emulation layer" on top of it ;-) We should also fix the bugs: the multiple callbacks issue shouldn't be hard to trackdown and fix. > So in Ement.el[5], I've been using a simple Curl wrapper library that > I've started.[6] It's rather primitive, but it seems to work well. I think it's important for Emacs to have a good HTTP API that works without any external dependency. It (technically) could be in any of the forms: - Including `curl` in Emacs' tarball. - Linking to some more-or-less standard HTTP library and exposing some API to ELisp. - Write it all in ELisp (like url.el does). If it can be done by improving url.el and growing a new API on top of it, that will be less painful. Stefan
