It's a kind of "macro" that is called an "entity". You can
define it
in an external file and then "include" it. Here is an
example:
In "document.docbook":
<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook V3.1//EN" [
<!ENTITY % magic-entities SYSTEM "magic.ent">
%magic-entities; <!-- This is where we include it -->
]>
<book lang="en">
...
<graphic fileref="flower.&jpeg-eps;"></graphic>
<!-- and here is where we use it -->
...
<graphic fileref="cactus.&gif-eps;"></graphic>
...
</book>
and in "magic.ent":
<!-- here we define it -->
<!ENTITY % html "IGNORE">
<![%html; [
<!ENTITY % print "IGNORE">
<!ENTITY gif-eps "gif">
<!ENTITY jpg-eps "jpg">
<!ENTITY jpeg-eps "jpeg">
]]>
<!ENTITY % print "INCLUDE">
<![%print; [
<!ENTITY gif-eps "eps">
<!ENTITY jpg-eps "eps">
<!ENTITY jpeg-eps "eps">
]]>
You need to pass "-i html" or "-i print" to jade so the
right extension is chosen at processing time. The
docbook-tools wrapper scripts do this.
It is quite rough, but it works.
