yuuji@518 7 ;;; Commentary:
yuuji@518 8 ;;;
yuuji@518 9 ;;; This lisp enables passing inline text to some external filter
yuuji@518 10 ;;; command to generate files such as graphic files.
yuuji@518 11 ;;;
yuuji@518 12 ;;; Typical situation is using blockdiag/dot(graphviz) command to
yuuji@518 13 ;;; generate png/pdf file.
yuuji@518 14 ;;;
yuuji@518 15 ;;; Example:
yuuji@518 16 ;;;
yuuji@518 17 ;;; [[LaTeX Source]]
yuuji@518 18 ;;; %#BEGIN FILTER{foo.pdf}{dot -T %t -o o}
yuuji@518 19 ;;; \if0
yuuji@518 20 ;;; ===
yuuji@518 21 ;;; digraph {
yuuji@518 22 ;;; A -> B;
yuuji@518 23 ;;; B -> C;
yuuji@518 24 ;;; }
yuuji@518 25 ;;; ===
yuuji@518 26 ;;; \fi
yuuji@518 27 ;;; %#END
yuuji@518 28 ;;; \includegraphics{foo.pdf}
yuuji@518 29 ;;;
yuuji@518 30 ;;; In this case above, when you type `[prefix] t e' between two
yuuji@518 31 ;;; `===' lines, the content in a region are fed to dot command as
yuuji@518 32 ;;; follows:
yuuji@518 33 ;;;
yuuji@518 34 ;;; echo TEXT | dot -T pdf -o foo.pdf
yuuji@518 35 ;;;
yuuji@518 36 ;;; Then foo.pdf file will be generated and the image (as PNG) will
yuuji@518 37 ;;; be displayed in the next window.
