whatdidido, the CLI for finding out what I was doing on a given day across all my git repos. I often use this to help me fill my Clockify entries (https://maelvls.dev/clockidup/)

whatdidido

#! /bin/bash

help() {
	cat <<EOF
I often need to remember what I was doing on a certain day. So I built
this tool to help me find that out. Note that it requires GNU date.

To configure which repositories are looked into, edit the EOF block at
the end of the source of this tool.

USAGE:

  whatdidido yesterday
  whatdidido "last friday"
  whatdidido "May 6, 2021"
  whatdidido "2021-05-06"

The date formats are the ones GNU date -d accepts. The output looks
like this:

  cert-manager-website 19:39 certificaterequest: more doc around approval api
  cert-manager 18:54 add a .golangci.yml so that we can all have same behavior
EOF
}

day_raw=
while [ $# -gt 0 ]; do
	case $1 in
	help)
		help
		exit 0
		;;

	*)
		day_raw="$1"
		;;
	esac
	shift
done

if test -z "$day_raw"; then
	echo "you need to give a day, e.g., 'yesterday' or 'last friday'" >&2
	exit 1
fi

if ! day=$(date -d "$day_raw" +"%Y-%m-%d"); then
	echo "could not parse day '$day_raw'" >&2
	exit 1
fi

while read -r project; do
	if ! test -d "$project/.git"; then
		continue
	fi

	# At first, I was using git log --before=... --after=... but it uses
	# the committer date, and since I rebase quite a lot, the committer
	# date does not reflect the day I actually worked on this commit.
	#
	# The workaround is to filter using awk:
