Cartesian raises an error when testing.

[nicaiola]

Hi guys

I just started playing around with Julia, I wanted to try Jutho's TensorOperations library out. As soon as I started to test it I got the error message below. For either

julia> Pkg.test("Cartesian")

I get the same error output.
Since I am very new here, I have no idea of how to fix it. Any tip/suggestion?

I'm surprised it's even loading this package; Cartesian (the best parts) are now in Base. CC @Jutho.

[Jutho]

I haven't tried Cartesian in julia v0.4. TensorOperations.jl itself certainly fails for other reasons. I have a newer version which is almost ready aside from updated documentation and discussing the changes/new features; unfortunately I won't have time to finalise this until after next week. It can already be tried by checking out the staged branch of TensorOperations.jl and looking at the examples in the test folder.

[nicaiola]

Many thanks @Jutho, I checked out the staged branch and the test goes though smoothly. However it doesn't load the IndexNotation...

julia> using TensorOperations, IndexNotation
ERROR: ArgumentError: IndexNotation not found in path
 in require at ./loading.jl:233

Am I supposed to load it also for this version?
The (first and) last line of the doc's example below fails in either case.

using TensorOperations, IndexNotation
alpha=randn()
A=randn(5,5,5,5,5,5)
B=randn(5,5,5)
C=randn(5,5,5)
D=zeros(5,5,5)
D[l"a,b,c"]=A[l"a,e,f,c,f,g"]*B[l"g,b,e"]+alpha*C[l"c,a,b"]

[Jutho]

Dear @nicaiola ; the docs are indeed outdated. IndexNotation is no longer needed and the way to use index notation has changed. See the test files for an example of the new syntax until the docs are updated. In case of further questions, please open an issue on the page of TensorToolbox.jl as we've drifted away from the original Cartesian.jl related error which is the focus of this issue.
