8 Configuring the Citation Engine ********************************* At the heart of Supercite is a regular expression interpreting engine called “Regi”. Regi operates by interpreting a data structure called a Regi-frame (or just “frame”), which is a list of Regi-entries (or just “entry”). Each entry contains a predicate, typically a regular expression, which is matched against a line of text in the current buffer. If the predicate matches true, an associated expression is ‘eval’uated. In this way, an entire region of text can be transformed in an _awk_-like manner. Regi is used throughout Supercite, from mail header information extraction, to header nuking, to citing text.
· Using Regi
· Frames You Can Customize
While the details of Regi are discussed below (
Using Regi),
only those who wish to customize certain aspects of Supercite need
concern themselves with it. It is important to understand though, that
any conceivable citation style that can be described by a regular
expression can be recognized by Supercite. This leads to some
interesting applications. For example, if you regularly receive email
from a co-worker that uses an uncommon citation style (say one that
employs a ‘|’ or ‘}’ character at the front of the line), it is possible
for Supercite to recognize this and _coerce_ the citation to your
preferred style, for consistency. In theory, it is possible for
Supercite to recognize such things as uuencoded messages or C code and
cite or fill those differently than normal text. None of this is
currently part of Supercite, but contributions are welcome!
