Turtle RDF Language Server for VS Code
Language support for RDF Turtle (.ttl) files: ontologies (OWL, RDFS,
SKOS), SHACL shapes and linked data. Powered by
turtle-lsp, a language server
written in Rust: a keystroke in a 30,000-line file gets fresh diagnostics in
about 9 ms.
Features
- Syntax highlighting for Turtle and RDF 1.2 (triple terms
<<( )>>, reifiers ~, annotations {| |}).
- Error checking as you type: syntax errors with recovery (one mistake does not hide the rest of the file), undeclared, unused and duplicate prefixes, invalid IRIs and language tags.
- Vocabulary checks: unknown or deprecated terms in 80+ well-known vocabularies (rdf, rdfs, owl, skos, sh, dcterms, foaf, schema.org, prov, sosa, qudt and more), with "did you mean" fixes. Matched by namespace IRI, so your own
ex: or sd: prefixes are never checked against the wrong vocabulary.
- Completion of prefixes and terms; type
Pers to get foaf:Person. Classes come first after a, properties in predicate position. Accepting a term adds its @prefix line for you.
- Hover with label, comment, types and where a resource is described.
- Navigation: go to definition, type definition (a resource's class), implementations (a class's instances and subclasses), find references, rename across files, document highlight.
- Outline, workspace symbol search and folding.
- Quick fixes: add a missing prefix, add all missing prefixes, remove an unused prefix, fix a misspelled term.
Project prefixes
If your Turtle files share a prefix header instead of declaring prefixes
themselves, put the header in a prefixes.ttl. Every Turtle file in that
folder or below can then use those prefixes. Or set turtle.prefixes.
Settings
turtle.prefixes: prefixes available in every file, e.g. { "ex": "http://example.org/" }.turtle.server.path: use a different turtle-lsp binary (user settings only; ignored in untrusted workspaces).turtle.trace.server: log the language server traffic to the Output panel.
Also for Neovim and other editors
The same server works in any editor that speaks the Language Server Protocol.
See the project README
for Neovim setup.
