+title: "2024, Day 29: First draft of a weeknote script"
+description: "I wrote a crufty script to automate weeknote creation"
+date: 2024-12-29T15:45:44-08:00
+draft: false
+---
+
+I finished [the Bash script I started]({{< relref
+"/december-adventure/2024-28/index.md" >}}) to help automate the creation of
+[the weeknotes I intent to post]({{< relref
+"/december-adventure/2024-25/index.md" >}}). It works for me, for now, but
+before I paste the code I want to call out the two biggest issues:
+
+First, it uses the non-POSIX `--date` flag to `DATE(1)`. I don't know how to
+make this work on any sort of BSD or macOS and I don't know if I ever will.
+
+More glaringly, messing with Git branches in a specific working tree is
+a really nasty hack. It would be way better to have this operate on its own
+clone of my website repo but I haven't set that up. My script launches an
+editor and if I get distracted and do something else to my website while
+that's open (more likely than you think), I could easily mess everything up.
+
+It would be better to have more of this handled by a [Hugo
+archetype](https://gohugo.io/content-management/archetypes/) but TBH
+I haven't even given that option much attention. I just wanted to get
+something together before the end of today and I did.
+
+```bash
+#!/usr/bin/env bash
+# Create or edit next Monday's weeknote
+
+set -eu
+
+HUGODIR=<path-to-hugo-root>
+POSTFILE=index.md
+WEEKSTR=$(date +"%G-W%V" --date="07:59 next Mon")
+POSTDIR=$(echo "content/posts/weeknotes/${WEEKSTR}" | tr A-Z a-z)
+
+pushd "$HUGODIR"
+GITCURRBRANCH=$(git branch --show-current)
+
+if ! grep -q "$WEEKSTR" <(git branch --list)
+then
+    git branch "$WEEKSTR" main
+fi
+git switch "$WEEKSTR"
+
+if [[ ! -d "$POSTDIR" ]]
+then
+    mkdir -p "$POSTDIR"
+fi
+pushd "$POSTDIR"
+
+if [[ ! -f "$POSTFILE" ]]
+then
+    # Fill in the frontmatter
+    cat << HERE > "$POSTFILE"
