SurveyJS Format

This is a specification based on what I can gather from the SurveyJS documentation.

Examples

{haveKids}='yes'

{haveKids}='yes' and {kids} >= 1

{var('have-kids')}='yes'

{matrix.name}='yes'

// "quality" is a matrix question, rowsWithValue is a custom function
rowsWithValue({quality}, 'disagree') >= 3

// "car" is a checkbox question
{car} notempty

{car} contains {item}

{car.length} > 1

{car} contains {item} and {item}!={bestcar}

{email} notempty or {phone} notempty or {skype} notempty
