Espresso.jl can't be loaded on julia 0.7-DEV
Closed this issue · 4 comments
Hi, @dfdx! As @lbenet has already told you, we're using Espresso.jl for some performance-oriented improvements in TaylorIntegration.jl (see discussion in PerezHz/TaylorIntegration.jl#31). We're trying to test this PR on julia nightlies, but it seems that Espresso cannot be loaded in julia 0.7-DEV (see this comment). For reference, I will reproduce the relevant REPL output here. If I try to load Espresso on julia 0.7-DEV at the Julia REPL, I get the following:

Is this a known issue? Are there any workarounds?
Many thanks in advance!
Hi and thanks for reporting. I haven't tested Espresso on Julia 0.7 yet, so most likely many features will be broken (especially these related to function body extraction since it heavily depends on Julia internals which seriously change in every major release). This concrete issue seems to be caused by incorrect macro expansion in (not very important) utilities. I'll try to fix it later today.
Are you on master of Espresso or some earlier commit?
Thank you for your reply! I'm on current latest master
Fixed, tests are now passing on Julia 0.7-dev, though there's still a bunch of deprecation warnings.
Let me know if you have any further issues.
Many thanks!
