Functions ¶

func ScanCalls ¶

func ScanCalls(input string, options CallScanOptions) ([]Call, []CallParseError)

ScanCalls parses function calls and returns parsed calls plus malformed-call errors.

Types ¶

type Call ¶

type Call struct {
	Name      string
	Args      []string
	Offset    int
	EndOffset int
	Dollar    bool
}

Call represents a parsed function call with offsets in the scanned input.

type CallParseError ¶

type CallParseError struct {
	Name    string
	Offset  int
	Message string
}

CallParseError represents a malformed call span.

type CallScanOptions ¶

type CallScanOptions struct {
	AllowedNames  map[string]bool
	RequireDollar bool
	AllowDollar   bool
	Strict        bool
}

CallScanOptions controls call scanning behavior.

type Declaration ¶

type Declaration struct {
	Kind   Kind
	Raw    string
	Offset int
	Args   []string

	// Normalized fields for known declarations.
	Target    string // first argument (alias/column)
	DataType  string // cast(... as type)
	Tag       string // tag(..., "...") payload
	Limit     string // set_limit(..., N)
	Connector string // use_connector(view, connector)
	Strategy  string // match_strategy(view, strategy)
	Partition string // set_partitioner(view, partitioner, concurrency)
	Size      string // compress_above_size(size)
	Value     string // generic second argument (batch_size, relational_concurrency, cardinality)
	Package   string // package(default/package)
	Alias     string // import(alias, package/path)
}

Declaration represents one parsed function declaration in DQL.

func Parse ¶

func Parse(dql string) ([]*Declaration, error)

Parse extracts declarations from original DQL text.

func (*Declaration) String ¶

func (d *Declaration) String() string

type Kind ¶

type Kind string

Kind identifies parsed declaration function.

const (
	KindCast                  Kind = "cast"
	KindTag                   Kind = "tag"

)
