Summary by CodeRabbit

  • New Features

    • Generated deployment READMEs now include format-specific setup and run instructions, machine and service details, exposed addresses, and guidance for credentials and required tools.
    • Scenario image and ignore files are generated with support for repository modules, released modules, and configured tools.
    • Jinja template checks are included in standard validation runs.
  • Improvements

    • Docker Compose output uses updated YAML formatting while preserving configured module paths and settings.
    • Deployment generation reports template-rendering and Compose serialization errors.

Walkthrough

et-cli adds Jinja-based generation for deployment files, scenario images, and READMEs. Docker Compose YAML generation now uses Serde serialization. The repository adds j2lint and a check that lints tracked Jinja templates.

Changes: Deployment output generation

Layer / File(s) Summary
Template rendering and generated configuration
Cargo.toml, utilities/cli/Cargo.toml, utilities/cli/src/templates.rs, utilities/cli/src/error.rs, utilities/cli/src/lib.rs, utilities/cli/src/deployment_types/mise.rs, utilities/cli/templates/{gitignore.j2,npmrc.j2,secrets.env.j2}
The CLI adds a Minijinja renderer and uses templates for npm configuration, secrets files, and .gitignore content. Template errors propagate through the generation paths.
Scenario image templates
utilities/cli/src/deployment_types/scenario_image.rs, utilities/cli/templates/scenario-image*
Dockerfile and Dockerignore generation uses templates and serializable context data instead of inline Rust string assembly.
Docker Compose serialization
utilities/cli/src/deployment_types/docker_compose.rs, utilities/cli/src/deployment_types/yaml.rs, utilities/cli/tests/scenario_generation.rs, verification/{local,published}/output/*/compose.yaml
Compose structures serialize through serde_saphyr. Rendering errors propagate, and verification outputs reflect the serializer’s YAML formatting. The test checks the parsed YAML build value.
README data and templates
utilities/cli/src/readme.rs, utilities/cli/src/lib.rs, utilities/cli/src/{deployment_types,expose,limits,recovery,schedule}.rs, utilities/cli/templates/readme*
A new README module assembles format-specific template data and writes the generated README. README content moves to Jinja templates, and related note-generation helpers are removed.
Jinja lint check integration
.mise/config.toml, .mise/locks/pipx-j2lint/1.3.0/pyproject.toml, CHECKS.md, Dockerfile.nanoserver, config/dprint.jsonc, config/semgrep/*
The repository pins j2lint and runs it on tracked Jinja templates through an aggregate check. Check documentation and template-related formatter and Semgrep configuration are updated.

Estimated code review effort: 4 (Complex) | ~60 minutes

Full details: Title check

Explanation

The title "Use Jinja templates" is short and names a real part of the change. The PR moves several generated outputs, including the README, Dockerfile, .dockerignore, .gitignore, npmrc, and secrets files, from handwritten Rust string assembly to Jinja templates rendered through a new templates.rs module. The title does not cover the other parts of the change, such as the Serde-based compose YAML serialization, the new j2lint tool, the new Cargo dependencies, and the Semgrep and dprint configuration updates. Those details are expected to be omitted from a short title. The title is therefore partially related to the main change, and it is specific enough that a teammate scanning history can see the primary intent.

Full details: Docstring Coverage

Explanation

Docstring coverage is 87.88% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 33 functions across 13 files. (2 skipped: 2 unsupported.)

Add the missing load-board.md.j2 template.

templates! embeds this file with include_str!, so its absence prevents et-cli from compiling. Both firmware.md.j2 and runner-board.md.j2 also include it.
