Essence LSP

An Essence Language Server Protocol (LSP) extension for VS Code, built on the Conjure-Oxide parser.

Features

• Essence language registration (.essence, .eprime)
• Syntactic error detection with diagnostics and underlining
• Semantic error detection with diagnostics and underlining
• Semantic highlighting
• Hover tooltips
• TextMate syntax highlighting

Requirements

This extension launches the conjure-oxide language server process.

Current implementation detail:

• if a local binary exists at target/release/conjure-oxide (relative to this repository layout), it is used;
• otherwise it falls back to conjure-oxide from your PATH.

To use the PATH fallback, install conjure-oxide and ensure it is available on your PATH. From this repository, one option is:

cargo install --path crates/conjure-cp-cli

You can verify installation with:

conjure-oxide --help

Development

From tools/vscode-ext:

npm install
npx @vscode/vsce package

To run in an Extension Development Host, use VS Code Run Extension from this folder/workspace.
