Tom, the coarseness encountered when trying splatfields with type parameters: is it endemic and likely to persist or does this grow better in v0.6+? On Thursday, September 15, 2016 at 11:20:35 PM UTC-4, Tom Breloff wrote: > > I like splatfields but I think it's hard to make work with type

[julia-users] Re: Re: dependent types in julia?

Hi Neal, It is not good practice to leave out parts of the template that Dan offers. While it may work with some test data, it is very likely to fail in general use (particularly by/with use from other packages) and it may become incompatible in some specific manner with future releases. If

[julia-users] building a package without rebuilding a REQUIRES pkg

If I have a package MainPkg with a REQUIRE file that holds "HelperPkg", and I do Pkg.add("HelperPkg");Pkg.build("HelperPkg"); is there a way to Pkg.add("MainPkg") without automatically rebuilding (the already current) HelperPkg?

Thanks for updating your work. If there is a form that allows a function to be defined that has multidispatch over trait and also over type, please provide an example. (If it is already there, please direct me to that example). On Wednesday, September 14, 2016 at 6:04:04 AM UTC-4, Mauro wrote: >

[julia-users] ANN: DelegationMacros v0.0.3

This offers updated macros to assist with delegating into/through fields of a defined type. Two macros apply a function to field value(s) yielding the functional result; and two others do that and then rewrap the result in the source type. The exports are: @delegate_oneField,

I have yet to enter my package into the Julia ecosystem by publishing it or manually forking METADATA etc. As I was about to do that, I managed to destroy my local METADATA for the package. I can, by erasing the entry in METADATA (& cache & lib) use PkgDev to re-register the package, but when I
