Lazy Git Bisect

A lot of times, especially during an incident, you want to run git bisect, but often finding a "good" commit is a challenge. I would rather just drop a date into git when I new things were working and deal with a few extra steps during the bisect.

I put these bash functions together to provide that functionality.

# call like `bisect_time "2022-07-01"` or just
# `bisect_time` to use yesterday's date
function bisect_time {
    since=${1:-$(date -d yesterday '+%Y-%m-%d')}
    good=$(git log --since="$since" --reverse --format="%H" | head -n 1)
    echo "HEAD is bad"
    echo "$good is good"
    git bisect start HEAD $good
    echo "use git bisect good/bad to mark commits"
}

# call like `bisect_time_with_test ./test.sh "2022-07-01"` or just
# `bisect_time_with_test ./test.sh` to use yesterday's date
function bisect_time_with_test {
    bisect_time "$2"
    git bisect run "$1"
}

Formatting Markdown with code blocks in Vim

I like to keep textwidth=80 when working on markdown documents so things are easier to read. However, documents with codeblocks often need to be longer. Using the built in format program results in vim constantly formatting your code in ways you didn't intend.

The way to solve this problem is to set a different formatter for markdown code. I do this with:

autocmd FileType markdown,vimwiki setlocal formatprg=fmtmd textwidth=80

fmtmd is a small python script that doesn't touch things in multiline code blocks. I have it set up as an executable and available on my path.

I made this little "secret knock" authentication library for fun.
