Overview ¶
package jsonpath is a template engine using jsonpath syntax, which can be seen at http://goessner.net/articles/JsonPath/. In addition, it has {range} {end} function to iterate list and slice.

Functions ¶
func UnquoteExtend ¶
UnquoteExtend is almost same as strconv.Unquote(), but it support parse single quotes as a string
Types ¶
type ArrayNode ¶
type ArrayNode struct { NodeType Params [3]ParamsEntry //start, end, step }
ArrayNode holds start, end, step information for array index selection
type FilterNode ¶
FilterNode holds operand and operator information for filter
func (*FilterNode) String ¶
func (f *FilterNode) String() string
type IdentifierNode ¶
IdentifierNode holds an identifier
func (*IdentifierNode) String ¶
func (f *IdentifierNode) String() string
type JSONPath ¶
type JSONPath struct {
// contains filtered or unexported fields
}
func (*JSONPath) AllowMissingKeys ¶
AllowMissingKeys allows a caller to specify whether they want an error if a field or map key cannot be located, or simply an empty result. The receiver is returned for chaining.
func (*JSONPath) FindResults ¶
type ParamsEntry ¶
ParamsEntry holds param information for ArrayNode
type Parser ¶
type RecursiveNode ¶
type RecursiveNode struct {
NodeType
}
RecursiveNode means a recursive descent operator
func (*RecursiveNode) String ¶
func (r *RecursiveNode) String() string
type WildcardNode ¶
type WildcardNode struct {
NodeType
}
WildcardNode means a wildcard
func (*WildcardNode) String ¶
func (i *WildcardNode) String() string
