Simplicial is currently incompartible 2ith julia 0.7 #14

Closed vitskov closed 5 years ago

vitskov commented 6 years ago

Julia v"0.7 seems to have forbidden backslashes in docstrings. Compilation results in the following error below. The culprit is the usage of \{ in the docstrings... Apparantly it's a known issue with 0.7, and somehow they decided to go ahead with this change without deprecation period.. See eg. https://discourse.julialang.org/t/lots-of-things-are-now-breaking-in-0-7/4943

I would rather leave this issue open than the 1.0 issue, per the PSA here: https://discourse.julialang.org/t/psa-use-julia-0-7-if-you-are-upgrading/13321 In short, v0.7 exists to bridge the gap between 0.6 and 1.0, providing warnings where 1.0 will cause errors.

In the next few days I'll look at getting CombinatorialCode and SimplicialComplex working with v0.7 (and 1.0).

most functions work fine in Julia 0.7
