	Locals []Variable `json:"locals"`
}

Function represents thread-scoped function information.

func ConvertFunction

func ConvertFunction(fn *gosym.Func) *Function

type Goroutine

type Goroutine struct {
	// ID is a unique identifier for the goroutine.

	// Current location of the goroutine
	CurrentLoc Location `json:"currentLoc"`
	// Current location of the goroutine, excluding calls inside runtime
	UserCurrentLoc Location `json:"userCurrentLoc"`
	// Location of the go instruction that started this goroutine
	GoStatementLoc Location `json:"goStatementLoc"`
}

Goroutine represents the information relevant to Delve from the runtime's internal G structure.

func ConvertGoroutine

func ConvertGoroutine(g *proc.G) *Goroutine

ConvertGoroutine converts from proc.G to api.Goroutine.

type Location

type Location struct {
	PC       uint64    `json:"pc"`

type Variable

type Variable struct {

	// Go type of the variable
	Type string `json:"type"`
	// Type of the variable after resolving any typedefs
	RealType string `json:"realType"`

	//Strings have their length capped at proc.maxArrayValues, use Len for the real length of a string
	//Function variables will store the name of the function in this field
	Value string `json:"value"`

	// Number of elements in an array or a slice, number of keys for a map, number of struct members for a struct, length of strings
	Len int64 `json:"len"`
	// Cap value for slices
	Cap int64 `json:"cap"`

	// Array and slice elements, member fields of structs, key/value pairs of maps, value of complex numbers
	// The Name field in this slice will always be the empty string except for structs (when it will be the field name) and for complex numbers (when it will be "real" and "imaginary")
	// For maps each map entry will have to items in this slice, even numbered items will represent map keys and odd numbered items will represent their values
	// This field's length is capped at proc.maxArrayValues for slices and arrays and 2*proc.maxArrayValues for maps, in the circumnstances where the cap takes effect len(Children) != Len
	// The other length cap applied to this field is related to maximum recursion depth, when the maximum recursion depth is reached this field is left empty, contrary to the previous one this cap also applies to structs (otherwise structs will always have all thier member fields returned)
	Children []Variable `json:"children"`

	// Unreadable addresses will have this field set
	Unreadable string `json:"unreadable"`
}

Variable describes a variable.
