[m17n-list] Can I define a function in a .mim input method file?

[Chen, Chien-ting]

I tried to write a input method with m17n. After I looked the tutorial
https://www.nongnu.org/m17n/manual-en/m17nDBTutorial.html , I've found
that it's under lisp-like language. But can I define a function in .mim
file?

for example:

(define (add1 x)

(+ 1 x)

)

and I can use (insert (add1 one-set-value)) to insert the number in the
text box.
