Then create a file in your home dir called
.pervert - the persistent variable register.
It can be an XML file or just a text file like
this
caliber 5.56
insulation none
tire 650B
LSD ALD-52
("just a text file" doesn't make it any less of
a database than an XML ditto by the way)
Now write a parser that will search the file
for e.g. the key "tire" and return the data
item "650B".
Because you said you at this point only have
a single variable, you don't need to worry
about sorting (at least not for the sake of an
algorithm parsing it being too slow), but it
can be nice to have it sorted anyway - and easy
to do like any Emacs buffer, even automatically
on insert - nice because you might come to
realize this file is handy also for
manual [1] use, e.g. when writing to the math
faculty and having to look up pi (3.1415..) and
so on :) No, seriously!
I'm pretty sure someone already did an Emacs
framework/interface to populate, change, and
retrieve data from such a text DB file?

intelligence service: Knowledge gives
strength to the hands.
