Artifacts

Starting with Julia 1.6, the artifacts support has moved from Pkg.jl to Julia itself. Until proper documentation can be added here, you can learn more about artifacts in the Pkg.jl manual at https://julialang.github.io/Pkg.jl/v1/artifacts/.

Julia 1.6

Julia's artifacts API requires at least Julia 1.6. In Julia versions 1.3 to 1.5, you can use Pkg.Artifacts instead.

Artifacts.artifact_metaFunction
artifact_meta(name::String, artifacts_toml::String;
              platform::AbstractPlatform = HostPlatform(),
              pkg_uuid::Union{Base.UUID,Nothing}=nothing)

Get metadata about a given artifact (identified by name) stored within the given (Julia)Artifacts.toml file. If the artifact is platform-specific, use platform to choose the most appropriate mapping. If none is found, return nothing.

Julia 1.3

This function requires at least Julia 1.3.

Artifacts.artifact_hashFunction
artifact_hash(name::String, artifacts_toml::String;
              platform::AbstractPlatform = HostPlatform())

Thin wrapper around artifact_meta() to return the hash of the specified, platform- collapsed artifact. Returns nothing if no mapping can be found.

Julia 1.3

This function requires at least Julia 1.3.

Artifacts.find_artifacts_tomlFunction
find_artifacts_toml(path::String)

Given the path to a .jl file, (such as the one returned by __source__.file in a macro context), find the (Julia)Artifacts.toml that is contained within the containing project (if it exists), otherwise return nothing.

Julia 1.3

This function requires at least Julia 1.3.

Artifacts.@artifact_strMacro
macro artifact_str(name)

Return the on-disk path to an artifact. Automatically looks the artifact up by name in the project's (Julia)Artifacts.toml file. Throws an error on if the requested artifact is not present. If run in the REPL, searches for the toml file starting in the current directory, see find_artifacts_toml() for more.

If the artifact is marked "lazy" and the package has using LazyArtifacts defined, the artifact will be downloaded on-demand with Pkg the first time this macro tries to compute the path. The files will then be left installed locally for later.

If name contains a forward or backward slash, all elements after the first slash will be taken to be path names indexing into the artifact, allowing for an easy one-liner to access a single file/directory within an artifact. Example:

ffmpeg_path = @artifact"FFMPEG/bin/ffmpeg"
Julia 1.3

This macro requires at least Julia 1.3.

Julia 1.6

Slash-indexing requires at least Julia 1.6.

Artifacts.artifact_existsFunction
artifact_exists(hash::SHA1; honor_overrides::Bool=true)

Return whether or not the given artifact (identified by its sha1 git tree hash) exists on-disk. Note that it is possible that the given artifact exists in multiple locations (e.g. within multiple depots).

Julia 1.3

This function requires at least Julia 1.3.

Artifacts.artifact_pathFunction
artifact_path(hash::SHA1; honor_overrides::Bool=true)

Given an artifact (identified by SHA1 git tree hash), return its installation path. If the artifact does not exist, returns the location it would be installed to.

Julia 1.3

This function requires at least Julia 1.3.

Artifacts.select_downloadable_artifactsFunction
select_downloadable_artifacts(artifacts_toml::String;
                              platform = HostPlatform,
                              include_lazy = false,
                              pkg_uuid = nothing)

Return a dictionary where every entry is an artifact from the given Artifacts.toml that should be downloaded for the requested platform. Lazy artifacts are included if include_lazy is set.
