Types

type Query

type Query struct {
	// contains filtered or unexported fields
}

func ParseQuery

func ParseQuery(
	q string,
	posAttrs []corpus.PosAttr,
	smapping corpus.StructureMapping,
) (*Query, error)

ParseQuery parses FCS-QL and returns an abstract syntax tree which can be used to generate CQL.

func (*Query) AddError

func (q *Query) AddError(err error)

func (*Query) Errors

func (q *Query) Errors() []error

func (*Query) Generate

func (q *Query) Generate() string

func (*Query) SetPosAttrs

func (q *Query) SetPosAttrs(attrs []corpus.PosAttr) *Query

func (*Query) SetStructureMapping

func (q *Query) SetStructureMapping(m corpus.StructureMapping) *Query

func (*Query) TranslatePosAttr

func (q *Query) TranslatePosAttr(qualifier, name string) string

TranslatePosAttr transforms a FCS-QL attribute specifier (e.g. `text`, `p_tag:pos`) into a real corpus positional attribute. Please note that it also supports `word` alias for the `text` layer

func (*Query) TranslateWithinCtx

func (q *Query) TranslateWithinCtx(v string) string
