README

dolo

Golang module for file download. Dolo skips downloading if the file exists and has the same content length. Dolo supports an optional callback that notifies on progress.

Exported methods

• NewClient(httpClient *http.Client, notify func(uint64, uint64)) - creates a new dolo client using the provided http.Client (with cookie jar, etc.) and an optional callback to notify on progress. Optional callback takes two values - downloaded bytes and total bytes.

• Download(url *url.URL, dstDir string, overwrite bool) - downloads a resource at the URL to the destination directory (original resource base path would be used for a filename). Overwrite would require download even if the destination file already exists and has the same content length.
