Access the information in installed Julia registries.
Julia's package manager stores package metadata in registries, which
consist of TOML files in a directory structure. For Julia 1.0 to 1.6
it was fairly straightforward to access this information with just a
TOML reader. Julia 1.7 introduced an option to locally store the
registry in an archive format (for very good performance reasons) and
restructured the package manager (
Pkg) code with an abstraction of
the registries (
RegistryInstance). Thus it is now better and easier
to use the
RegistryInstance abstraction, with the drawback that this
is considered an implementation detail in
Pkg and may change between
Julia minor versions.
About this Package
The whole purpose of RegistryInstances is to provide the
RegistryInstance abstraction without relying on
Pkg internals. The
advantages of getting it from here instead of from
- Does not change with Julia minor versions.
- The key structs and functions are exported and part of the public API. Therefore breaking changes will follow semantic versioning principles.
- Works with Julia 1.6 and up.
Initially this was based on an exact copy of
Pkg on August 12, 2021.
The public API consists of the structs
and the functions
