nomnoml_validate: Use the 'V8' JavaScript engine to validate a 'nomnoml'...

In nomnoml: Sassy 'UML' Diagrams

Use the V8 JavaScript engine to validate a nomnoml diagram.

Description

Although the nomnoml widgets render very quickly in the IDE, it can take a few seconds to grab a static screenshot and create a png file. In these situations it can be helpful to validate if the nomnoml JS library can parse a diagram.

This function returns TRUE if a diagram can be parsed, and FALSE otherwise. If FALSE the function also throws a warning.

Usage

nomnoml_validate(diagram = "[test]")

Arguments

diagram

A nomnoml diagram to validate

Value

Either TRUE or FALSE
