+    * Forked at [github.com/johnkerl/gocc](github.com/johnkerl/gocc).
     * This package defines the grammar for Miller's domain-specific language (DSL) for the Miller `put` and `filter` verbs. And, GOCC is a joy to use. :)
     * It is used on the terms of its open-source license.
   * [golang.org/x/term](https://pkg.go.dev/golang.org/x/term):

     * It is used on the terms of its open-source license.
 * See also [./go.mod](go.mod). Setup:

+
+2026-01-02 I used an Ubuntu 24.04 EC2 instance. I followed https://documentation.ubuntu.com/snapcraft/stable/. Error messages said things like
+

+
+Conclusion:
+
+* I got cryptic error messages with various permutations.
+* Through trial and error I got a `.snap` file with `sudo` and `multipass` and `--destructive-mode`.
+* Even then, I got a `.snap` file only for the current machine's arch, and the resulting `.snap` file was not locally installable.
+* This led me to try a GitHub Action.
+
+# Info from Claude about auto-releasing
+
+Here's how to set up automatic Snap publishing from GitHub releases:
+
+## 1. Create snapcraft.yaml
+
+First, ensure you have a proper `snapcraft.yaml` in your repo root (or in a `snap/` directory):
+
+```yaml
+name: your-app-name
+base: core22  # or core24 for Ubuntu 24.04
+version: git  # automatically uses git tags
+summary: Single-line summary
+description: |
+  Longer description of your application
+
+grade: stable  # or devel
+confinement: strict  # or classic, devmode
+
+apps:
+  your-app-name:
+    command: bin/your-binary
+    plugs:
+      - home
+      - network
+
+parts:
+  your-app:
+    plugin: nil  # change based on your build system (go, python, etc.)
+    source: .
+    # Add build steps as needed
+```
+
+## 2. Get Snapcraft credentials
+
+Export your Snapcraft login credentials:
+
+```bash
+snapcraft export-login --snaps=miller --channels=stable,candidate,beta,edge snapcraft-token.txt
+```
+
+This creates a token file with limited permissions for just your snap.
+
+## 3. Add token to GitHub Secrets
+
+1. Go to your GitHub repo → Settings → Secrets and variables → Actions
+2. Click "New repository secret"
+3. Name: `SNAPCRAFT_TOKEN`
+4. Value: Paste the entire contents of `snapcraft-token.txt`
+
+## 4. Create GitHub Action workflow
+
+Create `.github/workflows/release.yml`:
+
+```yaml
+name: Release to Snap Store
+
+on:
+  release:
+    types: [published]
+
+jobs:
+  snap:
+    runs-on: ubuntu-latest
+    steps:
+      - name: Checkout code
+        uses: actions/checkout@v4
+
+      - name: Build snap
+        uses: snapcore/action-build@v1
+        id: build
+
+      - name: Publish to Snap Store
+        uses: snapcore/action-publish@v1
+        env:
+          SNAPCRAFT_STORE_CREDENTIALS: ${{ secrets.SNAPCRAFT_TOKEN }}
+        with:
+          snap: ${{ steps.build.outputs.snap }}
+          # release: stable  # or edge, beta, candidate
+          release: edge
+```
+
+## Tips
+
+- **Version handling**: Using `version: git` in snapcraft.yaml automatically uses your git tag as the version
+- **Channels**: Start with `edge` channel for testing, then promote to `stable` once confident
+- **Multiple architectures**: Add a build matrix if you need to support arm64, etc.
+- **Testing before stable**: Consider publishing to `candidate` or `beta` first, then manually promote to `stable` after testing
+
+Now when you create a GitHub release with a tag (e.g., `v1.0.0`), the workflow will automatically build and publish your snap!
