 and then asking it to combine those along with its general knowledge of elisp to make edits to the buffer. im still unable to think of an actual use case in this contextyou cant think of an actual use case?as an example, heres an example of a problem that gpt can easily one shotin an ideal world, gptel could handle making the necessary edits, and i think using the functions api is a good way to do this.if nothing else, v version of this could literally only allow complete replacements of the existing text.it would still be useful for it to be able### Reply:
hmmm that api is basically exposing another argument like model name or temperature in which one can optionally convey an array of function declarations with optional docstrings when i saw this post the thought i had was maybe one wants to refactor a very large function or piece of code, currently that requires getting the full thing rewritten to then do an ediff possible from the refactor transient whereas it might be the case that the actual diff needed is tiny and perhaps this way gpt can convey it better via some funcalls and perhaps one could execute it straight from the reply to effect the change....but with ivanmalison latest reply it seems one doesnt have to actually give it actual elisp functions but instead a small set of simple made up text manip primitives which one can handle in the callback with actual elisp? safer and potentially more promisingalthough tbf, in the above case i would, in a gptel buffer, just ask it to reply with only a diff of what to change which id then try to apply by using the diffmode bindings to apply which might be very easy if one uses orgeditspecial on gpts diffmode replysince gptel supports custom callbacks via the lower level function gptelrequest that api can already be experimented with? the only minor missing piece would be a way to set that parameter in the curl...to tinker with the idea one can just defadvice override the curl args function to additionally hardcode in a functions argument?then itd be interesting to see some real use cases demoed via gptelrequest of something where this api lets one do something much better than currently possible
