Boolean Input Example

Location: examples/webapp/boolean/

This example demonstrates the <boolean> input type. Booleans accept logical true/false values. Rappture recognizes several equivalent default formats: on/off, yes/no, true/false, 1/0.

Script

import rappture2web.rp_library as Rappture

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

for eid, out_eid in [('iimodel', 'outb'), ('iimodel1', 'outb1'),
                     ('iimodel2', 'outb2'), ('iimodel3', 'outb3')]:
    val = rx['input.(%s).current' % eid].value
    rx['output.boolean(%s).about.label' % out_eid] = 'Echo of %s' % eid
    rx['output.boolean(%s).current' % out_eid] = val

rx.close()

Key concepts

• All four default formats (on, yes, true, 1) are treated identically by the framework.

• Boolean outputs echo the same format back.
