Eelco Dolstra	ea36f3b868	fetchFromGitHub: Use .tar.gz instead of .zip ... Also clean up the name attribute of fetchzip derivations a bit.	2014-05-09 15:53:44 +02:00
Eelco Dolstra	c8df888858	Add a function "fetchzip" ... This function downloads and unpacks a file in one fixed-output derivation. This is primarily useful for dynamically generated zip files, such as GitHub's /archive URLs, where the unpacked content of the zip file doesn't change, but the zip file itself may (e.g. due to minor changes in the compression algorithm, or changes in timestamps). Fetchzip is implemented by extending fetchurl with a "postFetch" hook that is executed after the file has been downloaded. This hook can thus perform arbitrary checks or transformations on the downloaded file.	2014-05-08 15:30:17 +02:00
