Language features

Diagnostics, hover, completion, go-to-definition, rename, and formatting via LSP.

Available on
  • Desktop

Glueprint runs Language Server Protocol (LSP) servers in the background and wires their results into Monaco. When you open a folder, the engine scans for the language servers it knows about and starts the ones that are installed.

Setup and per-server status live in Settings > Language servers. This page covers what you can do once an LSP is running.

Diagnostics

Errors, warnings, info, and hints from the LSP show up:

  • Inline in the editor with red / yellow / blue squiggles under the offending range.
  • In the gutter with severity icons.
  • In the minimap as colored marks.
  • In the Problems panel (Cmd/Ctrl+Shift+M) as a flat list across every open file.

Click any squiggle, gutter mark, or problems entry to jump to the source location.

Hover

Hover over a symbol to see its type signature, doc comment, and any extra info the language server exposes. The hover card supports markdown.

Completion

As you type, completion suggestions appear from the language server. Use arrow keys + Enter / Tab to accept. The list includes whatever the server provides — variable names, methods, snippets, imports, etc.

  • Go to Definition — right-click + Go to Definition, or hold Cmd/Ctrl and click.
  • Go to Declaration, Go to Type Definition, Go to Implementation — right-click menu when the LSP supports them.
  • Find All References — right-click + Find All References. Results land in the references panel.
  • Go to Symbol in Workspace — Cmd/Ctrl+T. See Find and quick-open.
  • Go to Symbol in File — through the Outline panel or the symbol mode of the palette.

Rename

Rename a symbol with F2 (or right-click + Rename Symbol). Glueprint uses the LSP’s rename support to update every reference across the project in one edit.

Code actions

The lightbulb that shows up next to certain lines is the LSP’s code actions — quick fixes for diagnostics, refactors, organize-imports, and so on. Click the lightbulb or use the keyboard shortcut your platform binds for code actions.

Formatting

Right-click + Format Document, or right-click + Format Selection, runs the LSP’s formatter on the buffer. Enable Format on Save in Editor preferences to run the formatter automatically every time you save.

Supported languages

Auto-discovery currently covers Rust, TypeScript, JavaScript, Python, Go, and PHP. The server has to be installed on the host — Glueprint doesn’t ship language servers; it just talks to ones already on your PATH or in the standard install locations. See Language servers for the setup story.
