Functions ¶
func CutFuncName ¶ added in v0.5.0
CutFuncName get pkg path and short func name
func FuncName ¶ added in v0.4.2
func FuncName(fn interface{}) string
FuncName get full func name, contains pkg path. eg:
// OUTPUT: github.com/gookit/goutil/stdutil.PanicIf stdutil.FuncName(stdutil.PkgName)
func GetCallStacks ¶ added in v0.4.2
GetCallStacks stacks is a wrapper for runtime. If all is true, Stack that attempts to recover the data for all goroutines.
from glog package
func GetCallerInfo ¶ added in v0.5.0
GetCallerInfo get caller func name and with base filename and line.
returns:
github.com/gookit/goutil/stdutil_test.someFunc2(),stack_test.go:26
func GetCallersInfo ¶ added in v0.4.2
GetCallersInfo returns an array of strings containing the func name, file and line number of each stack frame leading. NOTICE: max should > skip
func Go ¶ added in v0.4.2
Go is a basic promise implementation: it wraps calls a function in a goroutine and returns a channel which will later return the function's return value.
func MustString ¶
func MustString(v interface{}) string
MustString convert value(basic type) to string, will panic on convert a complex type.
func Panicf ¶
func Panicf(format string, v ...interface{})
Panicf format panic message use fmt.Sprintf
func PkgName ¶ added in v0.4.2
PkgName get current package name
Usage:
fullFcName := stdutil.FuncName(fn) pgkName := stdutil.PkgName(fullFcName)
func SimpleCallersInfo ¶ added in v0.5.0
SimpleCallersInfo returns an array of strings containing the func name, file and line number of each stack frame leading.
func WaitCloseSignals ¶ added in v0.4.2
WaitCloseSignals for some huang program.
Types ¶
type FullFcName ¶ added in v0.5.0
type FullFcName struct {
// FullName eg: github.com/gookit/goutil/stdutil.PanicIf
FullName string
// contains filtered or unexported fields
}
FullFcName struct.
func (*FullFcName) FuncName ¶ added in v0.5.0
func (ffn *FullFcName) FuncName() string
FuncName get short func name. eg: PanicIf
func (*FullFcName) PkgName ¶ added in v0.5.0
func (ffn *FullFcName) PkgName() string
PkgName string get. eg: stdutil
func (*FullFcName) PkgPath ¶ added in v0.5.0
func (ffn *FullFcName) PkgPath() string
PkgPath string get. eg: github.com/gookit/goutil/stdutil
func (*FullFcName) String ¶ added in v0.5.0
func (ffn *FullFcName) String() string
String get full func name string.
