com.eldrix.trud.impl.cache — com.eldrix/trud 1.0.110

Provides a simple caching mechanism for TRUD files.

This is deliberately not a generic download manager. It provides only a lightweight and synchronous cache for downloads.

download-url clj

(download-url url target)

Download a file from the URL to the target path. Parameters:

• url : a string representation of a URL.
• target : target (outputstream, writer or file).

get-archive-file clj deprecated

(get-archive-file dir release)

Get an archive file either from the cache or downloaded from TRUD. Returns result as a java.nio.file.Path.

get-release-file clj

(get-release-file dir release)

(get-release-file
  dir
  {url :archiveFileUrl file-size :archiveFileSizeBytes :as release}
  {:keys [progress]})

Get an archive file either from the cache or downloaded from TRUD.

make-cache clj

(make-cache dir)

(make-cache dir {:keys [progress download-fn] :or {download-fn download-url}})

Create a simple cache in the directory specified. Returns a function that can be used to download from a URL to a filename, that will use the directory as a cache. An optional validate function can be provided to check file size or checksum, for example. If progress is truthy, then progress will be printed. The resulting function will take a job (a map of :url :filename :file-size and :validate) and return a map of :cached and :f.
