countMatchingAnnotations(labbcat.url, expression)
URL to the LaBB-CAT instance
An expression that determines which annotations match. This must match by either id or layer.id. The expression language is currently not well defined, but is based on JavaScript syntax. e.g.
id == 'ew_0_456'
['ew_2_456', 'ew_2_789', 'ew_2_101112'].includes(id)
layerId == 'orthography' && !/th[aeiou].+/.test(label)
graph.id == 'AdaAicheson-01.trs' && layer.id == 'orthography' && start.offset > 10.5
layer.id == 'utterance' && all('word').includes('ew_0_456')
layerId = 'utterance' && labels('orthography').includes('foo')
layerId = 'utterance' && labels('participant').includes('Ada')
The number of annotations that match the expression.
if (FALSE) {
## count the number of topic tags that include the word 'quake'
countMatchingAnnotations(labbcat.url, "layer.id == 'topic' && /.*quake.*/.test(label)")
}
