Hello Mario,
ruote, behind the scene, is using RubyParser to get the parse tree of the
expression. "1x == 2x" is not valid Ruby, it results in a syntax error, so
ruote defaults to considering the whole as a string, "1x == 2x".
I've pushed this small change:
https://github.com/jmettraux/ruote/commit/7e18daacacf2f57d28f7a482729108d0d747ab21
that tries a bit harder if it finds something like "x == y" or "x != y".
Note that older versions of ruote (until 2.1 maybe), accepted "2x == 2x", so
with this commit, I'm moving back to a ruote that is more tolerant with its
conditions.
If there are objections with this commit, please raise your voice.
Cheers,
