labcode

The lc command-line interface for the labcode dialect of the Object-flow Programming Language. Installing this one package pulls in the ofplang toolchain and exposes it under a single command:

lc validate ...   # check a workflow is well-formed portable v0
lc schedule ...   # compute a schedule for a workflow
lc run ...        # execute a workflow on the labcode backend

labcode is where a site-specific dialect and a custom runner (real lab hardware) are developed on top of the ofplang toolchain. lc validate and lc schedule forward to the ofplang siblings unchanged; lc run is the labcode dialect's own runner: it drives the workflow on the labcode backend, running each device operation's script — supplied in the environment as an x-labcode.script extension on a process mode — out-of-process on a wall clock, so a long-running real operation never blocks the replan loop. See SPECIFICATIONS.md for the x-labcode extension.

Install

pip install labcode

Requires Python 3.10+. This package is a thin dispatcher; it depends on the ofplang sibling packages that do the work:

ofplang-validate — the validator
ofplang-schedule — the scheduler
ofplang-run — the runner / simulator

The language is defined in the ofplang/spec repository.

Usage

Each subcommand keeps its own options, exit codes, and --help:

lc --help            # top-level help
lc <command> --help  # command-specific options
lc --version

lc can also be run as a module: python -m labcode <command> ....
