Examples¶

Rhylthyme includes built-in example programs that demonstrate different features and environment types. You can open any example directly from the web app sidebar under Examples, or use the links below.

Built-in Examples¶

Breakfast Schedule¶

A kitchen program coordinating scrambled eggs, bacon, and toast in parallel.

Open in web app

• Environment: Kitchen
• Concepts demonstrated: Parallel tracks, variable durations, delayed starts (programStartOffset), resource constraints
• 3 tracks, resource constraints on stove burners and prep stations

Academy Awards Ceremony¶

An event program modeling the flow of an awards ceremony.

Open in web app

• Environment: Event
• Concepts demonstrated: Sequential ceremony segments, manual triggers, indefinite durations

Lab Experiment¶

A laboratory protocol with preparation, analysis, and cleanup phases.

Open in web app

• Environment: Laboratory
• Concepts demonstrated: Variable durations for analysis steps, sequential dependencies

Airport Gate Turnaround¶

An airport operations program coordinating aircraft unloading, servicing, and boarding.

Open in web app

• Environment: Airport
• Concepts demonstrated: Parallel service tracks, tight resource constraints, buffered triggers

Bakery Production Run¶

A bakery program managing multiple dough batches through mixing, proofing, and baking.

Open in web app

• Environment: Bakery
• Concepts demonstrated: Resource constraints on ovens and mixers, buffers between steps

Three Trays, One Oven¶

Three trays of cookies through one oven onto a rack that holds two. Each tray starts cooling as it comes out (instances: "each"), boxing waits for all three (instances: "all"), and maxInFlight: 2 holds the third bake until a rack slot is free.

• File: rhylthyme-examples/programs/cookies_three_trays.json
• Environment: Kitchen
• Concepts demonstrated: Per-instance chains, an explicit barrier, an in-flight limit distinct from maxConcurrent

Twelve Samples, One Rotor¶

Twelve samples aliquoted into a centrifuge rotor that holds six, spun and unloaded per sample, then pooled into two parallel thermocycler runs.

• File: rhylthyme-examples/programs/pcr_twelve_samples.json
• Environment: Laboratory
• Concepts demonstrated: maxInFlight: 6 on the rotor chain alongside thermocycler maxConcurrent: 2; a barrier feeding a replicated step

Four Arrivals, Two Taxiway Slots¶

Four aircraft land five minutes apart, taxi in and dock per aircraft; the apron holds two, so the third landing waits for the first aircraft to clear the gate. Baggage handling waits for every arrival.

• File: rhylthyme-examples/programs/airport_landings_taxi_gate.json
• Environment: Logistics
• Concepts demonstrated: maxInFlight over a staggered replicate, where the stagger delay is a minimum gap the gate may push out

JSON Structure¶

Every example follows the same structure. Here's a minimal program with two sequential steps:

{
  "programId": "hello-world",
  "name": "Hello World",
  "tracks": [
    {
      "trackId": "main",
      "name": "Main Track",
      "steps": [
        {
          "stepId": "greet",
          "name": "Greet",
          "task": "greeting",
          "duration": {"type": "fixed", "seconds": 5},
          "startTrigger": {"type": "programStart"}
        },
        {
          "stepId": "farewell",
          "name": "Farewell",
          "task": "farewell",
          "duration": {"type": "fixed", "seconds": 3},
          "startTrigger": {"type": "afterStep", "stepId": "greet"}
        }
      ]
    }
  ]
}

And here's a multi-track program with resource constraints:

{
  "programId": "pasta-dinner",
  "name": "Pasta Dinner",
  "tracks": [
    {
      "trackId": "pasta",
      "name": "Pasta",
      "steps": [
        {
          "stepId": "boil-water",
          "name": "Boil Water",
          "task": "cooking",
          "duration": {"type": "fixed", "seconds": 300},
          "startTrigger": {"type": "programStart"}
        },
        {
          "stepId": "cook-pasta",
          "name": "Cook Pasta",
          "task": "cooking",
          "duration": {"type": "fixed", "seconds": 600},
          "startTrigger": {"type": "afterStep", "stepId": "boil-water"}
        }
      ]
    },
    {
      "trackId": "sauce",
      "name": "Sauce",
      "steps": [
        {
          "stepId": "prep-vegetables",
          "name": "Chop Vegetables",
          "task": "preparation",
          "duration": {"type": "fixed", "seconds": 600},
          "startTrigger": {"type": "programStart"}
        },
        {
          "stepId": "cook-sauce",
          "name": "Cook Sauce",
          "task": "cooking",
          "duration": {"type": "fixed", "seconds": 900},
          "startTrigger": {"type": "afterStep", "stepId": "prep-vegetables"}
        }
      ]
    }
  ],
  "resourceConstraints": [
    {"task": "cooking", "maxConcurrent": 4, "description": "Stove burners"},
    {"task": "preparation", "maxConcurrent": 2, "description": "Prep stations"}
  ]
}

Manual Triggers¶

Steps can require user interaction. A step with a manual start trigger waits for you to click Start Step before it begins:

{
  "stepId": "manual-step",
  "name": "Quality Check",
  "task": "inspection",
  "duration": {"type": "fixed", "seconds": 30},
  "startTrigger": {"type": "manual"}
}

See the Manual Controls guide for details on how manual triggers, variable durations, and indefinite durations work during execution.

Buffered Triggers¶

Use afterStepWithBuffer to add a delay between steps:

{
  "stepId": "rest-dough",
  "name": "Rest Dough",
  "task": "resting",
  "duration": {"type": "fixed", "seconds": 3600},
  "startTrigger": {
    "type": "afterStepWithBuffer",
    "stepId": "knead",
    "bufferSeconds": 60
  }
}
