Demolab

A lab notebook for computational science — reproducible results, published and citable, run by a coding agent instead of a build system.

Coding agent setting someone up? Run uvx demolab-cli docs GETTING-STARTED, read the file it prints, and follow it strictly, step by step. (Human, setting up by hand? See Quickstart.)

You write a model or experiment once as a small program. Demolab runs it, captures everything it produced, stamps it with the exact code version, and publishes a clean page — figures, numbers, and real typeset maths — to both the web and PDF. The numbers on the page are read from the run, so they can't drift. You drive it all by talking to a coding agent; there's no web development or build config to touch.

Quickstart

Open your coding agent in an empty folder and paste:

Run uvx demolab-cli init here, then follow its GETTING-STARTED runbook strictly.

It lays your lab down, walks you through the toolchain (uv, typst) and your first experiment, one step at a time.

Set it up by hand instead?

Install uv and typst (brew install uv typst), then:

mkdir my-lab && cd my-lab
uvx demolab-cli init   # lab structure + git init — yours from the first commit
uv sync                # installs the deps and the `demolab` command

Then write your first experiment — ask your agent to follow GETTING-STARTED, or model one on a shipped reference (demolab docs STARTERS prints the dir; monte-carlo-pi is the canonical starter). demolab dev serves the site as you go. The engine lives in the demolab-cli package — updating it is uv lock --upgrade-package demolab-cli && uv sync.

What to ask your agent

Open your lab in your agent and say a runbook's name — it follows that runbook one step at a time. demolab docs lists them all (each is a plain file shipped in the package; demolab docs <NAME> prints its path). In this repo they live under demolab_cli/runbooks/.

Say… …and it will
GETTING-STARTED set you up end to end: scaffold, your first experiment live on a page, brand, publish
TOUR guided walkthrough of the lab — what's here, what it found, where to start
MIGRATE-CODE bring an existing codebase in, one experiment at a time
FROM-JUPYTER launder a Jupyter notebook into a reproducible, seeded experiment
MIGRATE-STACK write your tools in MATLAB / Julia / R / Octave instead of Python
EMBED-DOCS drop demolab into another project as a docs/ site
LINT check your writeups against the house style
DOCTOR audit the repo against the conventions
UPDATE update the engine package, leaving your content untouched

How it works

One decoupled loop: a tool computes → drops data → an experiment writes it up → the site publishes it. Every run records its exact parameters and the git commit it came from (stamped on the page), and tables read their numbers straight from the run — so prose and results can't disagree. A single Typst pass emits a website, a PDF per entry, and a book, all sharing the same live numbers.

The detail lives in the guides (in a lab: demolab docs <NAME>; in this repo, the files under demolab_cli/guides/):

  • RULES.md — the tool ↔ experiment contract, schemas, provenance, and how to add things.
  • STRUCTURE.md — the annotated file tree.
  • HOUSESTYLE.md — prose, maths, and figure style.
  • AGENTS.md — the agent entry point.

Commands

demolab shows them all. The everyday ones: init, docs, install, scaffold, dev, build, test. Run an experiment end-to-end directly: uv run python experiments/expNNN.py (there's no demolab run wrapper).
