TreadleForge Constrained Treadle Synthesis

Source: this release’s synthetic input → 7 output files. Observed 2026-09-08. Coverage: one example within the supported profile.

TreadleForge converts a liftplan for a rising-shed shaft loom into an equivalent tie-up and treadling sequence. It targets looms with up to eight shafts and eight treadles and performs a bounded exact search for a minimum-treadle solution that reproduces the same fabric. The result is a WIF-style draft you can review, but you should always check it against your actual loom's shaft and treadle limits before threading.

YOUR WORKSPACE

Turn your input into a checked artifact

Load the synthetic example to explore the format, or choose your own supported JSON file. Processing happens on this device. Your input is not uploaded. The first run downloads the processing engine.

Keep your original source. Unsupported inputs return an explanation. These workflows implement the stated mathematical or file-format checks; they do not establish physical performance, language quality or real-world reliability.

HOW TO USE IT

A repeatable input-to-output workflow

Provide your liftplan and loom constraints as JSON, within the eight-shaft and eight-treadle bounds.

The tool runs a bounded exact search for a tie-up and treadling that reproduce the liftplan using the fewest treadles.

You download the resulting draft and verify it against your loom before weaving.

OPTIONAL OFFLINE BATCH KIT

TreadleForge automation kit

$249 one time

Proposed one-time batch automation kit: a versioned ZIP with an offline CLI runner, the TreadleForge engine module, input fixtures, a verifier, and acceptance tests for compiling liftplans into tie-ups and treadling offline. No recurring updates or support are promised. Checkout is unavailable at publication until a provider connection is established.

Browser processing and result downloads above are free. The proposed kit bundles the same core engine with an offline command-line runner, synthetic fixtures, source, checksums and acceptance tests for repeated jobs.

Checkout is unavailable. You can use the browser workflow now. The kit cannot be purchased on this page yet.

A future purchase delivers the named version as a ZIP. No subscription, future updates, hosted storage or hands-on review is included. Pricing is an introductory offer experiment.

The interest page accepts contact details. Do not send your source files.

Before you start

Will it drive my loom?

No. It produces a draft for you to review and thread yourself; there is no loom control.

Is the treadle count truly minimal?

Within the declared eight-by-eight bounds it performs an exact search for a minimum-treadle solution.
