rappture2web 0.1.7

Web-based Rappture tool interface - renders XML tool definitions as interactive web applications

rappture2web

rappture2web turns Rappture tool XML definitions into interactive web applications — no desktop GUI required.

It reads a tool.xml file, renders the input form in a browser, runs the simulation backend, and displays the output visualizations (curves, fields, tables, maps, and more) in real time over WebSocket.

Features

• Drop-in replacement for the classic Rappture Python library (rp_library)
• Supports all common Rappture output types: curve, histogram, field (2D/3D/VTK/vector), table, sequence, image, string, number, log, mapviewer
• Interactive control panels: theme toggle, download (SVG/PNG/JSON), zoom, colorscale, legend position
• Compare mode: overlay multiple simulation runs on the same plot
• All JavaScript dependencies are bundled (Plotly 3.4, Three.js 0.128) — no CDN required

Installation

pip install rappture2web

Quick start

# Run an existing Rappture tool
rappture2web /path/to/tool/

# Or specify the tool.xml directly
rappture2web /path/to/tool/tool.xml

Then open http://localhost:8000 in your browser.

Tool script compatibility

Tool scripts require only a one-line change — replace the Rappture import:

# Before
import Rappture
rx = Rappture.PyXml(sys.argv[1])

# After
import rappture2web.rp_library as Rappture
rx = Rappture.PyXml(sys.argv[1])

All rx['input.(id).current'].value reads and rx['output.curve(f).component.xy'] = data writes work unchanged.

Supported output types

Type	Description
curve	XY line plots with legend, zoom, download
histogram	Bar histogram
field	2D heatmap, 3D scalar volume, VTK structured points, unstructured mesh, vector/flow
table	Data tables
sequence	Animated frame sequences
image	PNG/JPEG images
mapviewer	Geographic maps (scatter, choropleth, heatmap layers)
string, number, integer, boolean	Scalar outputs
log	Simulation log output
