# git-annex is written in Haskell which is currently not supported in
# spack, thus a similar approach as in the pandoc package was chosen. The
# following installs the standalone binaries for git-annex.
# git-annex does not use download links encoding the version but updates
# the "current" standalone file and keeps track of the version via
# git-annex itself
#
# Steps to find the static link e.g. for amd64:
# - $ git clone https://downloads.kitenet.net/.git/
# - $ cd downloads.kitenet.net
# - $ ls -l git-annex/linux/current/
# gives for example for amd64
# git-annex-standalone-amd64.tar.gz ->
# ../../../.git/annex/objects/KM/Ff/SHA256E-s51276461--a1cef631ef2cc0c977580eacaa1294d7617727df99214920ca6e8f3172bae03e.tar.gz/SHA256E-s51276461--a1cef631ef2cc0c977580eacaa1294d7617727df99214920ca6e8f3172bae03e.tar.gz
# - exchange "../../../" with "https://downloads.kitenet.net" and you have the link
# the version to the link can be found in
# git-annex/linux/current/git-annex-standalone-amd64.tar.gz.info
# Caution: the version on the webpage
# (meaning here: https://downloads.kitenet.net/git-annex/linux/current/) is
# broken and always behind
# if for some reason the sources vanish from https://downloads.kitenet.net/
# an alternative source can be found with
# - $ git annex whereis git-annex/linux/current/git-annex-standalone-arm64.tar.gz
