Gel extension for Visual Studio Code

Extension that provides support for Gel query language (EdgeQL) and Gel Schema Definition Language (ESDL).

(The color scheme used in the screenshot is Chromodynamics.)

Features

• syntax highlighting,
• syntax highlighting in embedded code blocks,
• error reporting via language server,

Language server

When activated (when .edgeql or .esdl files are opened) this extension will download and start gel-ls, which is the language server for the Gel database.

It will download it into .local/share/edgedb/gel-ls on Linux, into Library/Application Support/edgedb/gel-ls and MacOS or AppData/Roaming/edgedb/Data/gel-ls on Windows. If this installation exists or gel-ls is in system path, it will not be re-downloaded.

Currently, gel-ls supports a very limited set of features, including only syntax, type and name error reporting. It will read dbschema/ in the root of the workspace and use that schema to validate any queries found in the workspace.

Multi-workspace projects are not yet supported.

Syntax highlighting for embedded code blocks

This extension also provides syntax highlighting within string literals of other languages such as JavaScript and Go. To enable the highlighting, include # edgeql in a backtick-quoted string. This will make it easier to spot syntax errors and make your embedded queries more readable.

// Go
query := `#edgeql
select Example { * };
`

// JavaScript
const query = `
  # edgeql
  SELECT ... 
`;

Other languages are not yet implemented, but we are accepting pull requests at gel-editor-plugin.
