subzero's Issues

Errors with pp

The following protocol definition:

[Pointcheval Sanders credential showing]

pp: g~, X~, Y_1~, Y_2~
witness: age, pos, r

e(sigma_1', X~) * e(sigma_1', Y_1~^age * Y_2~^pos) * e(sigma_1', g~)^r = e(sigma_2', g~) // valid signature
& (age < 18 | pos = 17) // young or student

Has the issue that (1) the tilde symbol is not part of the LaTeX preview in the pp (it works in the proof statement, though) and (2) when trying to compile that protocol, the following exception is thrown:

[WARNING] /subzero/xtext-service/generate
java.lang.NullPointerException: Cannot invoke "org.cryptimeleon.subzero.model.GroupType.toString()" because the return value of "java.util.Map.get(Object)" is null

Commenting out the pp line makes the whole thing work.

Parentheses in LaTeX preview

Currently, a*(b+c) renders as a*b+c in the LaTeX preview. Same issue with foo ∧ (bar ∨ bar2).

The LaTeX preview generator should be made aware of operator precedence.

@jeremyfell can you take this? :)

Fix mobile layout

Currently, the layout on small screens is broken:

This is not incredibly high priority, but would probably be nice if the layout was more responsive :)
