Fetching remote data

If you define in kerblam.toml the section data.remote you can have Kerblam! automatically fetch remote data for you:

[data.remote]
# This follows the form "url_to_download" = "save_as_file"
"https://raw.githubusercontent.com/MrHedmad/kerblam/main/README.md" = "some_readme.md"

When you run kerblam data fetch, Kerblam! will attempt to download some_readme.md by following the URL you provided and save it in the input data directory (e.g. data/in).

Most importantly, some_readme.md is treated as a file that is remotely available and therefore locally expendable for the sake of saving disk size (see the data clean and data pack commands).

You can specify any number of URLs and file names in [data.remote], one for each file that you wish to be downloaded.

The download directory for all fetched data is your input directory, so if you specify some/nested/dir/file.txt, kerblam! will save the file in ./data/in/some/nested/dir/file.txt. This also means that if you write an absolute path (e.g. /some_file.txt), Kerblam! will treat the path as it should treat it - by making some_file.txt in the root of the filesystem (and most likely failing to do so). It will, however, warn you before acting that it is about to do something potentially unwanted, giving you the chance to abort.
