pliron IR for VS Code

Language support for pliron textual IR (.pliron, .plir), powered by pliron-lsp. The language server ships inside the extension, so there is nothing else to install.

Open a .pliron file inside a cargo project that defines pliron dialects. The server builds an analysis engine from your dialect crates in the background; the status bar shows pliron: building engine while it does. From then on your dialects' real parsers and verifiers drive everything:

  • diagnostics from the real parser and verifier (with error recovery);
  • semantic highlighting of ops, types, attributes, keywords, values, labels;
  • go to definition for values, blocks, @symbols, and op/type/attribute names, which jump into the dialect's Rust source;
  • references, rename, document highlight, outline, folding;
  • hover with exact types and the Rust docs of ops/types/attributes;
  • type inlay hints, completion with snippets from each op's format, and signature help;
  • quick fixes ("did you mean llvm.add?"), formatting, workspace symbols and call hierarchy for @functions.

When you save a dialect .rs file, the engine is rebuilt and swapped in automatically.

Commands

Command
pliron: Show Status Projects, engines, bundles and indexes.
pliron: View Engine Model The IR as the dialect engine understood it. Updates while you type.
pliron: View Syntax Tree The dialect-agnostic syntax layer's view.
pliron: Show Printed Form The document as the dialects' printers print it (what the round-trip check parses again).
pliron: Run Pass… Run one of the engine's passes (pliron's dce, and the dialects' own) on the document and show the IR before and after it as a diff.
pliron: Show Dialect Registry Ops, types and attributes defined in your dialect sources, with links.
pliron: Rebuild Dialect Engine Force a rebuild.
pliron: Open Generated Bundle Manifest The generated Cargo.toml of the engine.
pliron: Restart / Stop / Start Server, Show Logs, Show Server Version

Clicking the status bar item opens a menu with these commands.

Settings

Setting
pliron.server.path Use another pliron-lsp binary instead of the bundled one.
pliron.server.extraEnv Extra environment variables for the server and the engine builds it runs.
pliron.engine.enabled Turn dialect engines off (syntax features only).
pliron.engine.path Use one fixed engine binary for every file.
pliron.engine.idleTimeout Seconds without work after which an engine process stops; it starts again when needed (default 600, 0: never).
pliron.bundles.enabled Turn off automatic project engines.
pliron.diagnostics.roundTrip Warn about operations whose printed form does not parse back to the same IR (on by default).
pliron.trace.server Trace LSP traffic.

Building a project engine compiles your dialect crates, which runs their build scripts and proc macros. It therefore only happens in trusted workspaces.
