deprecate constructors with type as first argument #34
Conversation
|
Tests fail because of JuliaLang/Compat.jl#416 (comment), so need to wait for Compat v0.39. |

I had to split this into two methods to fix this on julia master:
julia> Test.detect_ambiguities(OffsetArrays, Base, Core)
Skipping Base.Date
2-element Array{Tuple{Method,Method},1}:
(similar(f::Union{Function, Type}, shape::Tuple{UnitRange,Vararg{UnitRange,N} where N}) in OffsetArrays at /Users/Fredrik/.julia/v0.7/OffsetArrays/src/OffsetArrays.jl:89, similar(::Type{T}, shape::Tuple) where T<:BitArray in Base at bitarray.jl:355)
(similar(f::Union{Function, Type}, shape::Tuple{UnitRange,Vararg{UnitRange,N} where N}) in OffsetArrays at /Users/Fredrik/.julia/v0.7/OffsetArrays/src/OffsetArrays.jl:89, similar(::Type{T}, shape::Tuple) where T<:Array in Base at array.jl:254)

Will the T version trigger your deprecation warning?

Yes there is some more stuff to work out here, see e.g. JuliaLang/julia#24785 (comment) I'm planning to take a look tonight. |

These two similar methods make me a bit uncomfortable.

What motivated their addition? Presumably a test failure?

Tests pass locally with JuliaLang/julia#24918 now, but not sure about those |

What about switching to uninitialized syntax now? We're moving now to ArrayType(iterator) constructs the array from the contents of iterator, but since -3:3 is an iterator it's ambiguous whether that's supposed to be treated as the initializing values or the axes.

I have that change as another PR in the pipeline, I can include it in this one if you prefer?

Either way is fine with me. I'll merge this and you can do that in a next one.
This type of
Arrayconstructors where deprecated in JuliaLang/julia#19989, soOffsetArraysshould do the same. Including the comma and the space, the replacement is even the same number of characters 😄
