Now that Julia 1.12-rc2 is out, I’d like to ask willing volunteers to test it together with a branch of Revise that supports redefining structs and other constants. The core functionality needed to support this feature is only in Julia 1.12+, but most of the aspects that make this usable (e.g., recreating existing methods to support the new types, redefining dependent types that may wrap a redefined type) will be implemented in Revise. Only by widespread testing is this likely to be released in robust form.
Trying the new version is easy:
juliaup add betaor whatever you need to do to install Julia 1.12-rc2julia +beta -e 'using Pkg; Pkg.add(name="Revise"; rev="teh/struct_revision")'- Now do your normal work, but using
julia +betaevery time you launch Julia
If you want to go back to the released version at any point, you can use pkg> free Revise.
One important thing to keep in mind: if you change a struct definition, you will need to recreate any data that involve that type. That is, if you’re working on code that accepts a list of Foo objects and you then redefine Foo, you will need to recreate list using the new Foo before you can pass it to any methods.
