Donkie dd16672a4a Parse the datetime range grammar in one place
The previous commit claimed the built-in timestamps and the datetime extra
fields share a grammar, then wrote that grammar out twice: once in
add_where_clause_datetime_opt for the typed columns, once inline in
add_where_clause_extra_field for the JSON-stored ones. Two copies of a
grammar drift, which would quietly falsify the thing the change was for.

The `<start>|<end>` split and its "at least one end" rule now live in
split_datetime_range_filter, which both call.

Only the parsing is shared, because only the parsing can be: an extra
field is JSON text in a joined key/value table, reached through a subquery,
while a built-in is a typed column on the row. The comparison that follows
the split therefore stays separate, and the two are not equivalent. The
built-in path parses the bound and compares real datetimes; the extra-field
path compares decoded ISO strings, so an offset or a missing '.000' changes
the answer there and not here. That asymmetry is now written down at both
sites, and tracked in #1057.

Keep track of your inventory of 3D-printer filament spools.

Spoolman is a self-hosted web service designed to help you efficiently manage your 3D printer filament spools and monitor their usage. It acts as a centralized database that seamlessly integrates with popular 3D printing software like OctoPrint and Klipper/Moonraker. When connected, it automatically updates spool weights as printing progresses, giving you real-time insights into filament usage.

Static Badge GitHub Release

Features

  • Filament Management: Keep comprehensive records of filament types, manufacturers, and individual spools.
  • API Integration: The REST API allows easy integration with other software, facilitating automated workflows and data exchange.
  • Real-Time Updates: Stay informed with live spool updates through Websockets, providing immediate feedback during printing operations.
  • Central Filament Database: A community-supported database of manufacturers and filaments simplify adding new spools to your inventory. Contribute by heading to SpoolmanDB.
  • Web-Based Client: Spoolman includes a built-in web client that lets you manage data effortlessly:
    • View, create, edit, and delete filament data.
    • Search, group and filter your inventory by manufacturer, material, location and more.
    • Add custom fields to tailor information to your specific needs.
    • Design and print labels with QR codes for easy spool identification and tracking.
    • Contribute to its translation into 18 languages via Weblate.
  • Database Support: SQLite, PostgreSQL, MySQL, and CockroachDB.
  • Multi-Printer Management: Handles spool updates from several printers simultaneously.
  • Advanced Monitoring: Integrate with Prometheus for detailed historical analysis of filament usage, helping you track and optimize your printing processes. See the Wiki for instructions on how to set it up.

Spoolman integrates with:

Web client preview: The Spoolman web client, showing the spool library with a spool's details open alongside it

The Spoolman dashboard, showing spools as draggable cards grouped by storage location The Spoolman label designer, showing a 50 by 25 mm spool label with a QR code, filament name and colour swatch
Dashboard — spools as cards, grouped by location or any other field. Drag one to move it. Label designer — QR labels built from any spool, filament or vendor field.

Installation

Please see the Installation page on the Wiki for details how to install Spoolman.

If the new client misbehaves on your setup, set SPOOLMAN_LEGACY_CLIENT=TRUE to go back to the previous one. Both ship in every release and talk to the same API, so your data is untouched either way — but please report the problem so it can be fixed.
