Editor tooling

Two plugins. One free, one paid.

.rxaml syntax highlighting is free today, in every editor we support. Pysar.Design is available for Rider on the JetBrains Marketplace, with a 30-day trial.

Pysar (syntax highlighting)

Completely free. No trial, no license.

The Pysar plugin colors .rxaml markup in your editor — elements, bindings, attributes. Nothing is gated, and nothing will be added later that changes that.

Pysar.Design

A visual designer for .rxaml reports

Drag, drop and preview bands, repeaters and bindings on a real paginated canvas — the same layout SkiaReportRenderer produces at build time, without leaving your IDE.

Pysar.Design is available for Rider. It's a paid plugin with a 30-day trial on the JetBrains Marketplace, and requires the free Pysar language plugin. Visual Studio and VS Code are available as manual downloads below. Install the matching Pysar language extension before the designer. Syntax highlighting stays free regardless.

Early Pysar.Design preview pane in Visual Studio, showing the same .rxaml source and rendered Annual Report side by side.

Paginated preview

Step through every page of a report, zoom, and see repeaters and detail bands resolve exactly as they will at render time.

Binding diagnostics inline

The same PQX010 / PQX011 checks the source generator runs at build time surface as editor diagnostics as you type.

Design-time data

Preview against d:DataContext sample data, so the layout is visible before real data exists.
