Reexport
Introduction
Maybe you have a module X
that depends on module Y
and you want using X
to pull in all of the symbols from Y
. Maybe you have an outer module A
with an inner module B
, and you want to export all of the symbols in B
from A
. It would be nice to have this functionality built into Julia, but we have yet to reach an agreement on what it should look like (see JuliaLang/julia#1986). This short macro is a stopgap we have a better solution.
Usage
@reexport using <modules>
calls using <modules>
and also re-exports their symbols:
module Y
...
end
module Z
...
end
module X
using Reexport
@reexport using Y
# all of Y's exported symbols available here
@reexport using Z: x, y
# Z's x and y symbols available here
end
using X
# all of Y's exported symbols and Z's x and y also available here
@reexport module <modulename> ... end
defines module <modulename>
and also re-exports its symbols:
module A
using Reexport
@reexport module B
...
end
# all of B's exported symbols available here
end
using A
# all of B's exported symbols available here
