README

Example helper scripts.

TODO:

  • All these need testing again and also the brew example.

Command for brew example

Brew example here

# hides the find command in a script.
./helpers/git-activity.sh --path="$(git root)/../"

Detect merged branches

If you use github web to squash and merge. It seems to make it difficult to determine if the branch was merged or not using --merged.

# uses git log to try and determine if branch was merged at some point
./helpers/git-merged-branches.sh --path="$(git root)"

# or give option to delete merged branches (git-extras)
./helpers/git-merged-branches.sh --path="$(git root)" --include-commits --delete-branches

Commit counts for master and PRs

# install sparklines shell script
brew install spark

# get prs and analyse commits 
./helpers/build_commits.sh --path="$(git root)" --hours 
./helpers/build_commits.sh --path="$(git root)" --days --json

# iterate over repositories
find ../../../code -maxdepth 1 -type d -exec ./build_commits.sh --path={} --ignore-errors --days \;

find ../../../code -maxdepth 1 -type d -exec ./build_commits.sh --path={} --days --json \;
find ../../../code -maxdepth 1 -type d -exec ./build_commits.sh --path={} --days --json \; | jq -s . > ./out/branch_activity.json  

# data generator
./helpers/build_commits_histogram_data.sh --action=histogram 
./helpers/build_commits_histogram_data.sh --action=histogram --repo="$(git root)"

# output sparkline
./helpers/build_commits_histogram_data.sh --action=histogram --repo=./ --sparkline | spark

Git repo sync

Split into two parts the first is the all up run it and update all repos that can be merged without conflict.

# will only merge repos that have no local edits.
./helpers/git_refresh_all_repos.sh -p="$(git root)/../" --merge

This is how it works step-by-step.

# out folder
mkdir -p ./out

./helpers/git_sync_status.sh --path="$(git root)" --status   
./helpers/git_sync_status.sh --path="$(git root)" --fetch
./helpers/git_sync_status.sh --path="$(git root)" --diff 
./helpers/git_sync_status.sh --path="$(git root)" --merge

# get repo status (sort so we can diff)
find ../../../code -maxdepth 1 -type d -exec ./git_sync_status.sh --path={} --status \; | jq -s '. | sort_by(.reponame)' > ./out/my_repos.json
