mwiegand 9a773093a8 fix(editor): correct caret behavior in autocomplete accept + disable auto-close Four smoke-discovered fixes in acceptCompletion / CodeJar options: - Backward selection walk via Selection.modify replaces the buggy range.setStart(endContainer, endOffset - fragment.length). The old code assumed the fragment lived in endContainer; at end-of-line the caret often sits in a post-Prism-<span> text node, so the subtraction went negative → IndexSizeError → caught silently → popup dismissed with no insert. - Save/restore caret around updateCode because codejar.js:469-474 does editor.textContent = code; highlight(editor) with no caret preservation, which dropped the caret to the start of the editor. - Set the selection inside the inserted text node before save() so CodeJar's save() doesn't trip its anchorNode === editor special case at codejar.js:122-127, which collapses to end-of-all-text. - addClosing: false on both CodeJar constructors so closing quotes don't duplicate — CodeJar's addClosing: true default inserts a paired closing character without skipping past an existing one, producing e.g. "rcon_password"" when you finish a string literal.

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
