Code used to extract history from BinaryBuilder.jl

[giordano]

Similarly to https://github.com/JuliaLang/Statistics.jl/issues/1, this is the script I used to extract the history of the relevant files in BinaryBuilder.jl:

#!/bin/sh

NEWPACKAGE="BinaryBuilderBase"

git clone -b master --single-branch --no-tags BinaryBuilder "${NEWPACKAGE}"
cd "${NEWPACKAGE}"

# https://ptc-it.de/move-files-to-new-repo-in-git/#
git filter-branch --prune-empty --index-filter \
    'git ls-tree -r -z --name-only --full-tree ${GIT_COMMIT} | \
     grep -z -v "Artifacts.toml" | \
     grep -z -v "src/compat.jl" | \
     grep -z -v "src/Sources.jl" | \
     grep -z -v "src/Dependencies.jl" | \
     grep -z -v "src/Prefix.jl" | \
     grep -z -v "src/Products.jl" | \

     grep -z -v "test/basic.jl" | \
     xargs -0 -r git rm --cached -r' -f -- --all
