BlockEnums

BlockEnums is like the built-in Enums. The main differences are

• Enumerated types are mutable in the sense that instances may be added after the type is created.
• The enumeration may be partitioned into blocks of values. For example @addinblock A 2 x would add the instance x to type A in the second block of indices.

julia> using BlockEnums

julia> @blockenum Fruit apple banana

julia> Fruit
BlockEnum Fruit:
apple = 0
banana = 1

julia> @add Fruit pear
pear::Fruit = 2

julia> Fruit
BlockEnum Fruit:
apple = 0
pear = 2
banana = 1

Some block features

julia> using BlockEnums

julia> @blockenum (Myenum, mod=MyenumMod, blocklength=100, numblocks=10, compactshow=false)

julia> @addinblock Myenum 1 a b c
c::Myenum = 3

julia> @addinblock Myenum 3 x y z
z::Myenum = 203

julia> BlockEnums.blockindex(MyenumMod.y)
3

Methods for functions in Base

Methods for the following functions in Base are defined and follow the established semantics.

• cconvert
• write, converts to the underlying bitstype before writing.
• read , reads a value from the bitstype and converts to the BlockEnum
• isless
• Symbol
• length
• typemin, typemax These are the min and max of values with names bound to them.
• instances
• print

Testing

BlockEnums passes JET.jl and Aqua.jl tests.
