Functions

func ParseCreatedLine

func ParseCreatedLine(createdLine string) (funcName string, IsMainThread bool)

ParseCreatedLine parses the second-to-last line of the stack trace. samples:

created by main.main
created by main.(*MyType).goroutine1
main.main()

func ParseFileLine

func ParseFileLine(fileLine string) (file string, line int)

ParseFileLine parses a line of a tab character then absolue file path, followed by a colon and line number, then a space character and a byte offset.

"\t/gp-debug-stack/debug-stack.go:29 +0x44"
"\t/opt/sw/parl/g0/waiterr.go:49"

func ParseFirstLine

func ParseFirstLine(debugStack string) (ID string, status string, err error)

getID obtains gorutine ID, as of go1.18 a numeric string "1"…

func ParseFuncLine

func ParseFuncLine(funcLine string) (funcName string, args string)

ParseFuncLine parses a line of a package name, optionally fully qualified, and a possible receiver type name and a function name, followed by a parenthesised argument list. samples:

main.main()
main.(*MyType).goroutine1(0x0?, 0x140000120d0, 0x2)
