07:52 Design #924: FlagManager for bool/bool3 flags

Is it possible to have a common interface for bool and bool3? maybe there should only be bool 3, where @uncertain3@ ... Anna Maria Bigatti

07:48 Design #924 (New): FlagManager for bool/bool3 flags

In many classes we have some bool/bool3 flags.
Setting a FlagManager class within, could help us keeping the same ki... Anna Maria Bigatti

In the end I chose @CoCoA_ASSERT_ALWAYS@ as it is pretty clear what it means.

The implementation now includes an *implicit* check that the ring of the given matrix is char 0; internally it simply... John Abbott

15:04 Feature #923: Fn to read symbol range (SymbolRange)

The code in @symbol.C:392@ which would call the NYI fn @ReadSymbolRange@ looks to be wrong to me.
John Abbott

15:03 Feature #923 (New): Fn to read symbol range (SymbolRange)

There is some initial code for reading a "range" of symbols from a string. This needs to be completed. John Abbott

18:17 Support #694: In test files: when is assert.H needed?

17:19 Support #694: In test files: when is assert.H needed?

Anna points out that if we do this for @assert.H@ then why shouldn't we do it for all header files... at which point ... John Abbott

16:38 Support #694 (In Progress): In test files: when is assert.H needed?

The explanation is fairly obvious (and simple): some header files already include @assert.H@. Here is the current li... John Abbott
