Problem with new version with packages that load other packages #48
Comments

Thanks! I am short on time, so let me just say it seems to work if you comment out this line. @vtjnash predicted this and proposed an alternative solution (#46 (comment)). |

In the short term, rather than a full glue package I suspect this might work: @require DataFrames="a93c6f00-e57d-5684-b7b6-d8193f3e46c0" include("extras_dataframes.jl")where using DataFrames
function mycoolfunction(df::DataFrame, ...)
body
endBut if you wanted that code precompiled you'd definitely want the auxillary module as proposed by @vtjnash. |

I don't understand why the original doesn't work, but the following patch seems to solve the problem in a similar usage case. diff --git a/src/require.jl b/src/require.jl

It would be better for compile times (and memory usage, and readability, and debugging / backtraces), if we could make this macro expand to a simple function call, rather than a dense nest of new function definitions: macro requires(pkg, expr)
id, modname = parsepkg(pkg)
return :(do_requires($__module__, $(QuoteNode(__source__.file)), $(QuoteNode(id)), $(QuoteNode(modname)), $(QuoteNode(expr))))
end

pkg = Base.PkgId(Base.UUID(id), modname))

@jmert that's very odd; can you send a PR and @davidanthoff can you confirm if that patch fixes things for you? I unfortunately can't reproduce this (on 0.7-beta) – maybe something has changed, it'd be good to verify. |
Will do. PR coming shortly. |
Interpolate PkgId expression, working around #48
Ok, now for a real problem with version v0.5.1 that has the @timholy rewrite.
I have a package that I stripped down to:
When I load it, I get:
If I then add
Reexportto my global environment, I get an error thatStatsBaseis not found.StatsBaseis the second package that is being used from DataFrames.jl.So I guess it looks as if a package A that is being required by package B won't properly load other packages that are in the REQUIRE file for A.
The text was updated successfully, but these errors were encountered:
