TesseraQL for Visual Studio Code

TesseraQL application authoring in the editor — the real linter's findings in the Problems panel, the CLI verbs as commands, and an app explorer. The design is docs/vscode-extension.md; the one stance to know: the extension holds no validation logic. It runs the project-selected tesseraql CLI and renders what it reports, so editor findings can never disagree with the build.

Features

• Lint on save. Saving any file inside an app home (a folder holding config/tesseraql.yml) runs tesseraql lint --format json and publishes every finding to the Problems panel at its source, line, and column. Finding codes link to the published error-code reference.
• Commands. TesseraQL: Serve / Test / Migrate / Admission / Package run the CLI verb in the integrated terminal; TesseraQL: Lint runs headless into the Problems panel.
• The explorer. A TesseraQL view in the Explorer sidebar: routes grouped by kind (web/, consume/, batch/, mcp/), views, migrations, and test suites — one click to the source.
• Error-code hovers. Hover any TQL-<DOMAIN>-<n> literal for a link into the error-code reference.
• Snippets for the blessed route shapes (tql-query-json, tql-query-html, tql-command, tql-view-list, tql-test).

Schema-driven completion stays with the scaffolded wiring: tesseraql new associates the committed JSON Schema through the recommended redhat.vscode-yaml extension. This extension complements it; it does not replace it.

Requirements

• The tesseraql CLI, 0.5.0 or later (lint --format json). Set tesseraql.cliPath if it is not on PATH — point it at the project's own CLI so editor findings always match the build.

Settings

Building from source

pnpm install
pnpm run test      # tsc + node:test over the editor-free core
pnpm run package   # produces tesseraql-vscode-<version>.vsix

Install the .vsix with Extensions: Install from VSIX… — marketplace publishing is tracked as an operator step in the design document.
