Plotwork command line

Check, draw, and sync Plotwork diagrams in your repository. A diagram is a few lines of text in a diagram fence of a Markdown file; plotwork sync draws it as a light and a dark SVG and writes the picture under the fence, so it shows on GitHub. It runs on your machine and in CI.

TL;DR

| Question | Answer | |---|---| | Does it need an account or a key? | No. | | Does it use the network? | No. It reads and writes only the files you name, and reads its own icon art from icons/ beside the program: an icon outside the few hundred most diagrams draw is read from there when a diagram uses it. The one request it can make is for a hosted picture link you give to read. | | Does it count anything? | No. It keeps no usage counts and sends none, whatever PLOTWORK_USAGE is set to. | | How do I run it? | npx @buun_group/plotwork <command>. | | Which Node version? | Node 22 or newer. | | Where is every option? | plotwork <command> --help prints one command's options, defaults, examples, and exit codes. The command reference has the same, one page for each command. | | How do I keep pictures in step in CI? | npx @buun_group/plotwork sync --check --format github "docs/**/*.md", or the Plotwork sync action. See Keep diagrams in sync in CI. | | Can a diagram come from my Terraform, Bicep, Pulumi, CloudFormation, CDK, Helm, Kustomize, Backstage, Structurizr, AsyncAPI, OpenAPI, or SQL files, or my pipelines? | Yes. Name the files in the sources of plotwork.config.json and run npx @buun_group/plotwork generate; generate --check fails when the files moved and the diagram did not. See Diagrams as code. | | Will the pictures look right in GitHub's dark mode? | Set "defaults": { "schemes": "auto" } in plotwork.config.json: sync and generate then write one SVG per diagram that follows the reader's light or dark setting, instead of a light and a dark file, and remove the old .dark.svg files they drew. See Diagrams as code. | | What do the pictures look like? | An arrow labelled with a verb, active or passive ("reads", "consumed by", "stored in"), draws that relationship's icon, and a sequence frame names its operator (alt, loop, par) in plain bold text in its corner. An icon= that names no icon is warning W208 (validate --strict fails on it) and the item draws its default icon, so a missing brand never stops a picture. | | Which licence? | MIT. Code and data from other people keep their own licences, listed in THIRD-PARTY-NOTICES.md. |

Commands

| Command | What it does | |---|---| | plotwork validate <file> [--strict] | Checks every diagram in a Markdown or diagram file. Each mistake has a line, a column, and a hint. --strict also fails on warnings, but not on style suggestions (W204, W205, W500). A hand-written arrow labelled with a verb ("reads", "publishes") draws its icon, and a group named "VPC", "Production" or "Kafka" takes its type. | | plotwork render <file> --out <svg> [--theme light\|dark\|auto] | Draws the first diagram to an SVG that carries its source. --no-embed-source leaves the source out. The file can be a view link from a Plotwork tool (viewUrl, svgUrl), in quotes: the diagram is read from it here, with no request. | | plotwork sync <files...> [--check] [--format github] | Writes the SVGs and the picture block under every diagram fence. Each word is a file, a folder, or a quoted glob. --check writes nothing and fails when a picture is stale; --format github prints each stale fence and each mistake as a GitHub annotation on its line. | | plotwork generate [--check] [--capture] [--source <name>] [--since <ref>] [--config <file>] [--format github\|json\|sarif\|junit] | Builds each diagram named in the sources of plotwork.config.json from its files (Terraform with its modules and environments, or a Terraform plan or state as JSON, Bicep, ARM, Pulumi, CloudFormation, a CDK cdk.out, OpenAPI, Compose, Kubernetes, Helm, Kustomize, a Backstage catalog, a Structurizr workspace, AsyncAPI documents (what each application receives drawn above it and what it sends below), SQL, Prisma, Drizzle, GitHub Actions workflows, GitLab CI/CD and Azure Pipelines pipelines, CSV, JSON, folders, git log), applies its overrides file, and writes the .diagram file or the Markdown fence and its pictures. Each imported arrow shows its relationship with an icon and a line colour (an eye for reads, a key for a grant), and every frame is typed, so it has its colour. --check writes nothing and fails on drift, naming each node and edge added, removed, or changed. --capture turns hand edits of a generated diagram into its overrides file. --since origin/main runs only the sources whose files changed since that git ref. --format sarif writes a report for code scanning and --format junit one for a test view, with the same exit code as --check. | | plotwork import <file> [--out <file>] [--write] | Converts Mermaid to Plotwork: a .mmd file to source, or every mermaid fence of a Markdown file (rewritten only with --write). | | plotwork read <file.svg\|link> [--out <file>] | Prints the source a Plotwork SVG carries, so it can be edited. | | plotwork export <file> --format confluence\|confluence-wiki\|notion [--image <link>] | Prints paste-ready text for Confluence or Notion. Without --image, the SVG is written beside it for you to upload. | | plotwork outline <file> | Prints a plain-text outline of every diagram. | | plotwork icons <query> | Searches the bundled icons. |

Exit codes: 0 when all is well, 1 for problems in the diagrams, 2 for a mistake in the command line.
