Package sdml-cli

This package is part of the Rust SDML project and specifically implements the sdml command-line interface (CLI). The project's intent is to provide an idiomatic implementation of the in-memory model, parser, generators, and the CLI tool.

The following figure demonstrates this package in the broader project context.

Installation

To install the command-line tool on MacOS or Linux use the Homebrew package manager and the SDML Tap. Installing in this way also installs dependencies such as GraphViz and PlantUML used for diagram generation.

❯ brew install sdm-lang/sdml/sdml

You can check that you have the tool installed and on the path with the following check.

 ❯ sdml versions               
SDML CLI:        0.2.7
SDML grammar:    0.2.16
Tree-Sitter ABI: 14

Install via cargo

Cargo is usually installed with the Rust toolchain using rustup.

The following command should download and build the tool, and will also work to install any updates.

❯ cargo install sdml-cli

Cargo will sometimes report that you have the latest version installed, to be sure you can force it to install regardless with the --force option.

❯ cargo install sdml-cli --force

Install from source

To install the CLI from source you need to clone the entire repository.

❯ git clone https://github.com/sdm-lang/rust-sdml.git

In the rust-sdml directory you can build/test/install using the following commands.

❯ cargo build
❯ cargo test
❯ cargo install --path sdml-cli

Global Options

Certain command-line options act on all commands, these must appear before the command. The SDML tool has a log-filter and a no-color global option.

The set of packages making up rust-sdml all have extensive logging which can be enabled when running the tool. The global argument --log-filter takes a log level and displays any log event with a severity greater than, or equal to, the filter.

❯ sdml --log-filter tracing versions
2024-02-20T19:06:53.141741Z  INFO sdml: Log level set to `LevelFilter::Tracing`
2024-02-20T19:06:53.141877Z TRACE sdml: Commands::execute self: Versions
SDML CLI:        0.2.7
SDML grammar:    0.2.16
Tree-Sitter ABI: 14

Some of the commands will, by default, use colored output which can be a problem if you save a file for future processing as the control characters play havoc with diff tools for example.

❯ sdml --no-color versions
❯ NO_COLOR=1  sdml versions
❯ CLI_COLOR=0 sdml versions

Representation Conversion

This command (convert) allows the conversion of a module from the SDML surface syntax into one of a number of alternate representations.

RDF

This uses the surface to RDF mapping defined in the SDML Language Reference. The mapping is normative and stable.

JSON

This is a direct representation of the in-memory model in the Rust package sdml_core in JSON. This mapping is non-normative and may change according to any model structure change.

S-Expression

This is a debugging representation, and supported as the underlying tree-sitter library uses s-expressions as a parse-tree visualization.

Dependency Visualization

This command (dep) generates a representation of the transitive closure of dependencies for a given module into one of a number of alternate representations.

As Text Tree

Show dependencies as a text tree with the original as the root.

❯ sdml deps sdml
sdml
├── owl
│   ├── rdf
│   │   └── rdfs
│   │       └── rdf
│   ├── rdfs
│   └── xsd
│       ├── rdf
│       └── rdfs
├── rdf
├── rdfs
├── skos
│   ├── rdf
│   └── rdfs
└── xsd

In some cases the entire set of dependencies is not necessary and the --depth argument can be added to only show a number of levels of import from the root. The depth argument instructs to command to stop after that many dependencies away from the original module. Setting depth to 1 will only show the direct dependencies of the original.

❯ sdml deps --depth 1 sdml
sdml
├── owl
├── rdf
├── rdfs
├── skos
└── xsd

As GraphViz Graph

Create an SVG representation of the dependency graph using GraphViz.

❯ sdml deps --output-format graph sdml > sdml-deps.svg
❯ open -a Safari sdml-deps.svg

As RDF Statements

Create a set of RDF statements,as N-Triples, that represent the individual OWL import relationships.

❯ sdml deps --depth 1 --output-format rdf sdml

Diagram Generation

This command (draw) generates diagrams of a module with different perspectives.

Concept Diagram

❯ sdml draw --diagram concepts --o example-concepts.svg -i example/example.sdm
❯ open -a Safari example-concepts.svg

Entity Relationship Diagram

❯ sdml draw --diagram entity-relationship --o example-erd.svg -i example/example.sdm
❯ open -a Safari example-erd.svg

UML Class Diagram

❯ sdml draw --diagram uml-class --o example-uml.svg -i example/example.sdm
❯ open -a Safari example-uml.svg

Document (Project) Generation

This command (doc-book) creates structured documentation for a collection of modules, and includes annotations, constraints and all definition types. The generated documentation also include diagrams and dependency graphs.

In Org-mode

Create an Emacs org-mode formatted file. This format allows all content to be written into a single file with export options to HTML, LaTeX, Word, PDF and more.

Document (Module) Generation

This command (doc) creates structured documentation for a module, and includes annotations, constraints and all definition types. The generated documentation also include diagrams and dependency graphs.

In Org-mode

Create an Emacs org-mode formatted file. This format allows all content to be written into a single file with export options to HTML, LaTeX, Word, PDF and more.

In Markdown

Create a markdown formatted file, this file uses GitHub-flavored markdown to allow for some better content formatting than CommonMark.

Module Highlighting

TBD

XRef Tag Generation

TBD

Validation

This command (validate) provides deep validation of a module's content, including errors, warnings, and linter-like advice. Checks are run not only on the initial module, but it's transitively loaded dependencies.

❯ sdml validate --level all -i examples/errors/i0506.sdm
note[I0506]: identifier not using preferred casing
  ┌─ examples/errors/i0506.sdm:1:8
  │
1 │ module Example <https://example.com/api> is
  │        ^^^^^^^ this identifier
  │
  = expected snake case (snake_case)
  = help: for more details, see <https://sdml.io/errors/#I0506>

note[I0506]: identifier not using preferred casing
  ┌─ examples/errors/i0506.sdm:3:13
  │
3 │   structure access_record is
  │             ^^^^^^^^^^^^^ this identifier
  │
  = expected upper camel case (UpperCamelCase)
  = help: for more details, see <https://sdml.io/errors/#I0506>

Additionally, a short-form option will generate diagnostics using a CSV format that is easier for tools to parse. The fields in this format are: severity, file name, start line, start column, end line, end column, error code, and message.

❯ sdml validate --level all --short-form -i examples/errors/i0506.sdm
note,examples/errors/i0506.sdm,1,8,1,15,I0506,identifier not using preferred casing
note,examples/errors/i0506.sdm,3,13,3,26,I0506,identifier not using preferred casing

Version Information

This command (versions) shows more information than the simple --version global argument and is useful for debugging.

❯ sdml versions               
SDML CLI:        0.2.7
SDML grammar:    0.2.16
Tree-Sitter ABI: 14

Module Viewer

This command (view) will generate source code from a module file, which at first seems redundant. However, this view provides levels of detail that allow for an overview of module definitions. The --level argument can be used to elide content and get an overview of a module.

Definitions Only

Show only the definitions in the module, any definition body will be elided, for an overview of the module contents. Elided definitions are followed by ";; ...".

❯ sdml view --level definitions -i examples/example.sdm
module example <https://example.com/api> is

  import [ dc xsd ]

  datatype Uuid <- sdml:string ;; ...

  entity Example ;; ...

end

Members

Show definitions in the module and show the members of product types and variants of sum types but not their bodies if present.

❯ sdml view --level members -i examples/example.sdm
module example <https://example.com/api> is

  import [ dc xsd ]

  datatype Uuid <- sdml:string ;; ...

  entity Example is
    version -> Uuid
    name -> sdml:string ;; ...
  end

end

Full

Show all contents of the module.

❯ sdml view --level full -i examples/example.sdm
module example <https://example.com/api> is

  import [ dc xsd ]

  datatype Uuid <- sdml:string is
    @xsd:pattern = "[0-9a-f]{8}-([0-9a-f]{4}-){3}[0-9a-f]{12}"
  end

  entity Example is
    version -> Uuid
    name -> sdml:string is
      @dc:description = "the name of this thing"@en
    end
  end

end
