Hello,

I am using MetaEdit+ to describe a small language for automation. What I want to do is to map my objects states with signal states; meaning say a Switch object with property 'state' (fixed list) [Pressed, Released], I want to map that with [1, 0]. Is there a way to add that on top of my language?

DSM is about raising the level of abstraction, so the default answer would be that the language should be human-readable - just Pressed/Released - and the generator should be responsible for mapping that to 1/0.

With just two values, you can simply say "if :state='Pressed' then '1' else '0' endif". If there were more values, I often like to put the mapping as a http://www.metacase.com/support/55/manuals/mwb/Mw-6_5_5.html" rel="nofollow - translator rather than logic:

to '%stateValue$Pressed $1
$Released $0'
endto

:state%stateValue

If some strings on the left-hand side of the translator are substrings of later strings, either re-order or switch to using more precise regular expressions like /^Pressed$/.
