* gptel.el (gptel-send, gptel--insert-response,
gptel--url-get-response): Remove aio dependency, turn aio-defuns
into regular functions. This requires splitting `gptel-send' into
"before response" and "after response" functions, but the ability
to debug the code fully is worth the inconvenience. The new "after
response" function is `gptel--insert-response'.
* gptel-curl.el (gptel-curl--sentinel, gptel-curl-get-response):
Turn aio-defuns into regular functions.
gptel.el (gptel--debug, gptel--url-parse-response): Add a debug
flag that shows the http response. Fix json parsing error.
gptel-curl.el (gptel-curl--sentinel): Ditto.
gptel.el (gptel--url-get-response): When `gptel-send' is called
directly, the API key is assumed to exist. Ensure that it is read.
gptel-curl.el (gptel-curl--get-args): Ditto.
gptel-curl.el (gptel-curl--process-alist, gptel-curl--get-args,
gptel--curl-sentinel, gptel-curl--parse-response): Rename internal
functions and variables to use the `gptel-curl--` prefix instead of
`gptel--curl-`.
gptel.el (gptel--system-message, gptel--system-message-alist,
gptel--model, gptel--temperature, gptel--max-tokens,
gptel--request-data): Add new buffer-local variables to hold API
parameters. Generating the full request data plist is now done in a
separate function, `gptel--request-data'.
gptel-curl.el (gptel-curl-get-response): Rename from `gptel--curl-get-response'
and autoload it to ease its use in `gptel-send'. Remove Version header
identifying gptel-curl as a separate package and make it require `gptel' instead.
Conditionally solves #2.
gptel.el (gptel-use-curl, gptel-parse-response, gptel--playback,
gptel-send, gptel-playback): New user options `gptel-playback',
`gptel-use-curl`. The former controls whether the response is played
back in chunks, which is done by the function `gptel--playback'. The
response returned by `gptel-get-response' and `gptel--curl-get-response'
is now a plist with the content and status.
gptel-curl.el (gptel--curl-get-args, gptel--curl-get-response,
gptel--curl-sentinel): Add support for curl when available. Set it to
the default. `url-retrieve' is full of fangs that multibyte you.
