🦀 Qlue-ls 🦀

⚡Qlue-ls (pronounced "clueless") is a blazingly fast language server for SPARQL, written in Rust 🦀, build for the web.

If you want to use Qlue-ls, check out the documentation. To learn more about the origin story of this project, read the blog post.

🚀 Capabilities

Here is a quick overview what Qlue-ls can do. A more detailed list can be found in the documentation.

📐 Formatting

Formats SPARQL queries to ensure consistent and readable syntax. Customizable options to align with preferred query styles are also implemented.

🩺 Diagnostics

Diagnostics provide feedback on the query. Diagnostics come in severity: error, warning and info

✨ Completion

Completion provides suggestions how the query could continue.

For completion of subjects, predicates or objects the language server sends completion-queries to the backend and gets the completions from the knowledge-graph.

These completion queries have to be configured for each knowledge-graph.

🛠️ Code Actions

Code action suggest complex changes to your input. Often in the form of a quickfix, to fix a diagnostic.

ℹ️ Hover

Get information about a token on hover.

🕳 Jump

Quickly jump to the next or previous important location in the query.

❓ operation identification

Determine if a operation is a query or update.

⚙️ Configuration

Qlue-ls can be configured through a qlue-ls.toml or qlue-ls.yml file.

Detailed exmplanations can be found in the documentation.

Here is the full default configuration

[format]
align_predicates = true
align_prefixes = true
separate_prologue = false
capitalize_keywords = true
insert_spaces = true
tab_size = 2
where_new_line = true
filter_same_line = true

[completion]
timeout_ms = 5000
result_size_limit = 100

[prefixes]
add_missing = true
remove_unused = false
