Info on "Simple Expression Language" for custom formulas?

[Jan-Hendrik Spieth]

JPD documentation states:

Write Your Own

Write your own allows you to use a simple expression language to write their own formula.

There seems to be no further info on that "simple expression language" in the documentation.

• Which functions are available? (tried normalize(...) - yields "Could not parse")
• Which operators? (mathematical operators are obviously possible)

Any info on that?

And what's on the roadmap, relating to the custom expressions?

Thanks a lot!

Hello Jan, 
Thanks for reaching out. We've addressed this issue and added a cheat sheet. I hope you find it useful. 
Thanks!

Yep, that's what I was looking for, thanks @María !

Are there any plans for adding more functions/operators, such as "normalize()"?
