Functions

func Equal

func Equal(code1, code2 string) bool

Equal check if the two assert expression is equal, (mainly ignore the white space charactors)

func Execute

func Execute(code string, reader KV) (bool, error)

Execute directly run the code with the reader

func ExecuteMap

func ExecuteMap(code string, data map[string]interface{}) (bool, error)

ExecuteMap is a convenient function to execute code with data

func MustExecute

func MustExecute(code string, reader KV) bool

MustExecute is same with Execute, but panic if has error

func MustExecuteMap

func MustExecuteMap(code string, data map[string]interface{}) bool

MustExecuteMap is same with ExecuteMap, but panic if has error

Types

type Assert

type Assert struct {
	*sync.Mutex
	// contains filtered or unexported fields
}

Assert 代表一个表达式

func New

func New(code string) (*Assert, error)

New 编译代码生成表达式

func (*Assert) Error

func (l *Assert) Error(s string)

Error 为 yacc 所用

func (*Assert) Execute

func (l *Assert) Execute(kv KV) (bool, error)

Execute 使用参数中给定的变量, 执行表达式并返回结果 执行过程中出现任何错误都会返回 error, 比如字符串与数字比较等等

func (*Assert) Lex

func (l *Assert) Lex(lval *yySymType) int

Lex 为 yacc 使用

type KV

type KV interface {
	Get(key string) interface{}
}

func NewKV

func NewKV(data map[string]interface{}) KV

NewKV is inner default KV

type Value

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

Value represents a variable in expression

func NewValue

func NewValue(name string, v interface{}) Value

NewValue create a new value
