In most cases, all that is necessary to begin using Supercite is to add the following to ~.emacs:
(add-hook 'mail-citation-hook 'sc-cite-original)
For more details of the process, read on…
Hitting C-c C-y in your MUA’s reply buffer yanks and cites the
original message into the reply buffer. In reality, the citation of the
original message is performed via a call through a configurable hook
variable. The name of this variable has been agreed to in advance as
part of the citation interface specification. By default this
hook variable has a nil
value, which the MUA recognizes to mean,
“use your default citation function.” When you add Supercite’s
citation function to the hook, thereby giving the variable a
non-nil
value, it tells the MUA to run the hook via
run-hooks
instead of using the default citation.
Early in Supercite’s development, the Supercite author, a few MUA
authors, and some early Supercite users got together and agreed upon a
standard interface between MUAs and citation packages (of which
Supercite is currently the only known add-on :-)
. Supercite can
probably be used with most Emacs MUAs, with a greater or lesser degree
of effort.
To learn exactly how to connect Supercite to the software systems you are using, read the appropriate following sections. For details on the interface specifications, or if you are writing or maintaining an MUA, see Hints to MUA Authors.
The first thing that everyone should do, regardless of the MUA you are using is to set up Emacs so it will load Supercite at the appropriate time. This happens automatically if Supercite is distributed with your Emacs version. If not, you can set up an autoload for Supercite.
To do the latter, put the following in your .emacs file:
(autoload 'sc-cite-original "supercite" nil t)
The function sc-cite-original
is the top-level Supercite function
designed to be run from the citation hook. It expects
‘point’ and ‘mark’ to be set around the region to cite, and it
expects the original article’s mail headers to be present within this
region. Note that Supercite never touches any text outside this
region. Note further that the region need not be active
for sc-cite-original
to do its job.
See Hints to MUA Authors.
The other step in the getting connected process is to make sure your
MUA calls sc-cite-original
at the right time. As mentioned
above, some MUAs handle this differently. Read the sections that follow
pertaining to the MUAs you are using.
