# Typical command to generate the list of tarballs:
|
|
|
|
# export i="mirror://xorg/X11R7.7/src/everything/"; cat $(PRINT_PATH=1 nix-prefetch-url $i | tail -n 1) | perl -e 'while (<>) { if (/(href|HREF)="([^"]*.bz2)"/) { print "$ENV{'i'}$2\n"; }; }' | sort > tarballs-7.7.list
|
|
# manually update extra.list
|
|
# then run: cat tarballs-7.7.list extra.list old.list | perl ./generate-expr-from-tarballs.pl
|
|
# tarballs-x.y.list is generated + changes for individual packages
|
|
# extra.list are packages not contained in the tarballs
|
|
# old.list are packages that used to be part of the tarballs
