> *Decentralized Emacs: Self-hosted elisp evaluation via GitHub Actions*

## Core Concept

GitHub Actions as a **decentralized Emacs compute fabric**:
- Trigger elisp evaluation from local Emacs
- GitHub runners execute `emacs --batch --eval`
- Results stream back via workflow artifacts or gh CLI
- Self-hosted runners = your own Emacs cloud

```
┌─────────────────┐    gh workflow run    ┌──────────────────┐
│  Local Emacs    │ ─────────────────────▶│  GitHub Actions  │
│  (controller)   │                       │  (emacs --batch) │
└────────┬────────┘                       └────────┬─────────┘
         │                                         │
         │  gh run watch / artifacts               │
         ◀─────────────────────────────────────────┘
```

```

## Workflow: Full Interactive Session

```
1. C-c g h         → Open gh-emacs transient
2. s r             → Search repos (consult-gh-search-repos)
3. <select repo>   → Embark: c=clone, f=fork, v=view
4. After clone:
   - N f f         → forge-fetch (get issues/PRs)
   - N l p         → forge-list-pullreqs
   - <select PR>   → M-x gh/ai-review-pr
5. Create PR:
   - N c p         → forge-create-pullreq
   - M-x gh/ai-generate-pr-description
```

## Decentralized Elisp Evaluation

### GitHub Actions Workflow Template

```yaml
# .github/workflows/elisp-eval.yml
name: Elisp Eval
on:
  workflow_dispatch:
    inputs:
      elisp_code:
        description: 'Elisp code to evaluate'
        required: true
        type: string
      emacs_version:
        description: 'Emacs version'
        default: '29.4'
        type: string

jobs:
  eval:
    runs-on: ubuntu-latest
    steps:
      - uses: purcell/setup-emacs@master
        with:
          version: ${{ inputs.emacs_version }}
      
      - name: Evaluate Elisp
        id: eval
        run: |
          result=$(emacs --batch --eval "${{ inputs.elisp_code }}" 2>&1)
          echo "result<<EOF" >> $GITHUB_OUTPUT
          echo "$result" >> $GITHUB_OUTPUT
          echo "EOF" >> $GITHUB_OUTPUT
      
      - name: Upload Result
        uses: actions/upload-artifact@v4
        with:
          name: elisp-result
          path: |
            /tmp/elisp-output.txt
```

### Self-Hosted Runner for Persistent Emacs

```yaml
# .github/workflows/elisp-self-hosted.yml
name: Self-Hosted Elisp
on:
  workflow_dispatch:
    inputs:
      elisp_code:
        description: 'Elisp to evaluate'
        required: true

jobs:
  eval:
    runs-on: [self-hosted, emacs]  # Your labeled runner
    steps:
      - name: Eval with persistent Emacs daemon
        run: |
          emacsclient --eval "${{ inputs.elisp_code }}" \
            || emacs --batch --eval "${{ inputs.elisp_code }}"
```

### Trigger from Local Emacs

```elisp
(defun gh-emacs-remote-eval (code &optional repo)
  "Evaluate CODE on GitHub Actions runner.
REPO defaults to current repository."
  (interactive "sElisp code: ")
  (let* ((repo (or repo (gh-emacs--current-repo)))
         (escaped-code (shell-quote-argument code)))
    (async-shell-command
     (format "gh workflow run elisp-eval.yml -R %s -f elisp_code=%s"
             repo escaped-code))
    (message "Dispatched to %s - use gh run watch to monitor" repo)))

(defun gh-emacs-remote-eval-buffer ()
  "Send current buffer to remote Emacs for evaluation."
  (interactive)
  (let ((code (buffer-substring-no-properties (point-min) (point-max))))
    (gh-emacs-remote-eval
     (format "(progn %s)" code))))

(defun gh-emacs-remote-eval-region (start end)
  "Send region to remote Emacs for evaluation."
  (interactive "r")
  (gh-emacs-remote-eval
   (buffer-substring-no-properties start end)))
```

### Fetch Remote Results

```elisp
(defun gh-emacs-fetch-result (run-id &optional repo)
  "Fetch result artifact from RUN-ID."
  (interactive "nRun ID: ")
  (let* ((repo (or repo (gh-emacs--current-repo)))
         (cmd (format "gh run download %d -R %s -n elisp-result -D /tmp/gh-elisp"
                      run-id repo)))
    (shell-command cmd)
    (find-file "/tmp/gh-elisp/elisp-output.txt")))

(defun gh-emacs-watch-run (run-id &optional repo)
  "Watch RUN-ID and fetch result when complete."
  (interactive "nRun ID: ")
  (let* ((repo (or repo (gh-emacs--current-repo))))
    (async-shell-command
     (format "gh run watch %d -R %s && gh run download %d -R %s -n elisp-result"
             run-id repo run-id repo))))
```

### Batch Queue Pattern (actions-batch inspired)

```elisp
(defvar gh-emacs-batch-queue nil
  "Queue of elisp jobs to dispatch.")

(defun gh-emacs-batch-enqueue (code priority)
  "Add CODE to batch queue with PRIORITY."
  (push (list :code code :priority priority :time (current-time))
        gh-emacs-batch-queue)
  (setq gh-emacs-batch-queue
        (sort gh-emacs-batch-queue
              (lambda (a b) (> (plist-get a :priority)
                               (plist-get b :priority))))))

(defun gh-emacs-batch-dispatch-all ()
  "Dispatch all queued jobs to GitHub Actions."
  (interactive)
  (dolist (job gh-emacs-batch-queue)
    (gh-emacs-remote-eval (plist-get job :code)))
  (message "Dispatched %d jobs" (length gh-emacs-batch-queue))
  (setq gh-emacs-batch-queue nil))
```

### Self-Hosted Runner Setup

```bash
# On your server/container:

# 1. Download runner
mkdir actions-runner && cd actions-runner
curl -o actions-runner-linux-x64-2.311.0.tar.gz -L \
  https://github.com/actions/runner/releases/download/v2.311.0/actions-runner-linux-x64-2.311.0.tar.gz
tar xzf ./actions-runner-linux-x64-2.311.0.tar.gz

# 2. Configure with Emacs label
./config.sh --url https://github.com/OWNER/REPO \
  --token YOUR_TOKEN \
  --labels emacs,elisp-eval

# 3. Install Emacs
sudo apt-get install emacs

# 4. Start persistent daemon
emacs --daemon

# 5. Run the runner
./run.sh
```

### Gay.jl Integration for Job Coloring

```elisp
(defvar gh-emacs-job-colors
  '((queued . "#63B6F0")
    (in_progress . "#ED6BDB") 
    (completed . "#89DF91")
    (failure . "#CF6971")
    (cancelled . "#8E9EDF"))
  "Colors for job states.")

(defun gh-emacs-colorize-job (job-status)
  "Get color for JOB-STATUS."
  (alist-get (intern job-status) gh-emacs-job-colors "#D1E598"))
```

## Transient Menu (Updated)

```elisp
(transient-define-prefix gh-emacs-transient ()
  "Decentralized Emacs via GitHub Actions."
  ["Remote Eval"
   ("e e" "Eval expression" gh-emacs-remote-eval)
   ("e b" "Eval buffer" gh-emacs-remote-eval-buffer)
   ("e r" "Eval region" gh-emacs-remote-eval-region)]
  ["Jobs"
   ("j w" "Watch run" gh-emacs-watch-run)
   ("j f" "Fetch result" gh-emacs-fetch-result)
   ("j l" "List runs" gh-emacs-run-list)]
  ["Batch"
   ("b q" "Enqueue job" (lambda () (interactive) 
                          (gh-emacs-batch-enqueue (read-string "Code: ") 
                                                  (read-number "Priority: " 5))))
   ("b d" "Dispatch all" gh-emacs-batch-dispatch-all)]
  ["Local"
   ("s r" "Search repos" consult-gh-search-repos :if (lambda () (fboundp 'consult-gh-search-repos)))
   ("p l" "PR list" gh-emacs-pr-list)
   ("i l" "Issue list" gh-emacs-issue-list)])

(global-set-key (kbd "C-c g h") 'gh-emacs-transient)
```
