Artifacts

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.

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.

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.

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"

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).

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.

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.
