[developers] semi.vpm and trigger rules (and KNOPPIX+LKB)

[Sanghoun Song]

Dear All,

I tested this on my ubuntu machine (not KNOPPIX+LKB) with my toy
Japanese grammar, and found that trigger rules do not work properly
either. I also found that the following line in semi.vpm causes the
problem.

* >> u

If the line is removed, the generation works correctly with trigger.mtr.
As a test, I added the following two lines into lkb/mrsglobals.lsp,
but the trigger rules still do not work.

(setf *show-lnk-p* nil)
(setf *variable-type-mapping* :semi)
