Migrating a Pull Request (PR) from the Julia repository to this repository

Since this package was split out from the main Julia repository, you might have previously made a pull request (PR) to the Julia repo. You can easily migrate such PRs to this repository using the following steps:

1. Add the Julia repository (or your fork) as a new remote repository:

   git remote add juliarepo https://github.com/JuliaLang/julia
   

2. Fetch the commits from the Julia repository:

   git fetch juliarepo
   

3. Cherry-pick the relevant commits made in the Julia repository to this repository:

   git cherry-pick $JULIA_COMMIT
   

Using development versions of this package

This package performs some type piracy and is also included in the sysimage, which makes using a development version slightly more complex than usual.

To use a development version of this package, you can choose one of the following methods:

1. Change the UUID in the project file and load the package: This approach will produce warnings and may lead to method ambiguities between the development version and the one in the sysimage, but it can be used for basic experimentation.

2. Build Julia with the custom LinearAlgebra commit: Modify the commit in stdlib/LinearAlgebra.version and build Julia.

3. Build a custom sysimage with the new LinearAlgebra:

   • Install PackageCompiler.
   • Load it and, with this project active, run:

     create_sysimage(["LinearAlgebra"]; sysimage_path="new_sysimage.so", incremental=false, filter_stdlibs=true)
     

   • Start Julia with the custom sysimage:

     julia -Jnew_sysimage.so
