Download files from the Internet and keep them up-to-date.

The package can be installed through Julia's package manager:

Pkg.add("RemoteFiles")

Remote files are declared through the @RemoteFile macro:

using RemoteFiles

@RemoteFile(JULIA_BINARY, "https://status.julialang.org/download/win64",
    file="julia-nightly-x64.exe", updates=:daily)

# Download the file if it is out-of-date
download(JULIA_BINARY)

# Check whether the file has been downloaded
isfile(JULIA_BINARY)

# Get the path
path(JULIA_BINARY)

By default the file is downloaded to Pkg.dir(CURRENT_PACKAGE)/data. This can be customized with the dir keyword argument to the @RemoteFile macro.

RemoteFiles can be grouped together in a RemoteFileSet:

@RemoteFileSet BINARIES "Julia Binaries" begin
    win = @RemoteFile "https://julialang-s3.julialang.org/bin/winnt/x64/0.7/julia-0.7.0-win64.exe"
    osx = @RemoteFile "https://julialang-s3.julialang.org/bin/osx/x64/0.7/julia-0.7.0-osx10.7+.dmg"
end

# Download all of them

download(BINARIES)

Note that there is also a function-interface with RemoteFile and RemoteFileSet, see their docstrings.

RemoteFiles.jl will try to download files via the cURL command-line tool by default and automatically fall back to use wget or HTTP.jl if the download fails or the respective binaries are not available.
