feat(editor-v2): editor.js glue (mount, submit-capture, files alias) 
Un-bundled progressive-enhancement glue:
- DOMContentLoaded → mount cm6 on every textarea[data-editor-language].
- Each <form> gets one capture-phase submit handler that copies every
  contained editor's getValue() into its textarea.value before the
  browser serializes the form (submit-time copy bridge).
- The textarea with class files-editor-content (the files-modal
  textarea) exposes its controller as window.__filesEditor for
  files-overlay.js's getValue / setContent / setLanguage calls.
- 'auto' language resolves from the modal's filename input
  ([data-editor-filename]); a language [data-editor-language-select]
  dropdown lets the user override.
- Vocab fetched lazily on the first srccfg mount; cached for the page.

Falls through silently if window.__editor isn't defined (bundle
failed to load), keeping the raw textarea visible — no-JS fallback.

README.md

l4d2-web-app

Flask web app for managing L4D2 servers through user-private blueprints.

Key v1 behaviors

  • Local username/password login; no public signup
  • Admin-managed overlay catalog
  • Private blueprints per user
  • Server creation from blueprints (live-linked; no per-server blueprint overrides)
  • Async job model with persisted command logs in job_logs
  • Desired vs actual state model
  • Live logs for jobs and servers via SSE endpoints
  • Host operations go through l4d2ctl via a local host command runner, not direct l4d2host imports

Frontend constraints

  • Server-rendered templates (Jinja)
  • Vendored HTMX (static/vendor/htmx.min.js)
  • Custom CSS only
  • Tokenized, consistent link and accent colors

Development

From the workspace root (../):

uv sync          # creates .venv, installs l4d2host + l4d2web editable, plus dev deps
uv run pytest l4d2web/tests -q

Configuration

The web app reads these settings from the environment:

  • DATABASE_URL: SQLAlchemy database URL, for example sqlite:////var/lib/left4me/left4me.db.
  • SECRET_KEY: Flask secret key used for sessions and CSRF-sensitive state.
  • JOB_WORKER_THREADS: number of background job worker threads.

In the systemd deployment, environment is loaded from /etc/left4me/host.env and /etc/left4me/web.env.

Admin Bootstrap

Create the first admin account with the Flask CLI. Provide the password through LEFT4ME_ADMIN_PASSWORD:

LEFT4ME_ADMIN_PASSWORD='change-me' flask create-user <username> --admin
