var ErrNoAttachPath = errors.New("must specify executable path on macOS")

ErrNoAttachPath is the error returned when the client tries to attach to a process on macOS using the lldb backend without specifying the path to the target's executable.

Types

type AddrLocationSpec 

type AddrLocationSpec struct {
	AddrExpr string
}

func (*AddrLocationSpec) Find 

func (loc *AddrLocationSpec) Find(d *Debugger, scope *proc.EvalScope, locStr string) ([]api.Location, error)

type AmbiguousLocationError 

type AmbiguousLocationError struct {
	Location           string
	CandidatesString   []string
	CandidatesLocation []api.Location
}

func (AmbiguousLocationError) Error 

func (ale AmbiguousLocationError) Error() string

type Config 

type Config struct {
	// ProcessArgs are the arguments to launch a new process.
	ProcessArgs []string
	// WorkingDir is working directory of the new process. This field is used
	// only when launching a new process.
	WorkingDir string

	// AttachPid is the PID of an existing process to which the debugger should
	// attach.
	AttachPid int

	// CoreFile specifies the path to the core dump to open.
	CoreFile string
	// Backend specifies the debugger backend.
	Backend string
}

Config provides the configuration to start a Debugger.

Only one of ProcessArgs or AttachPid should be specified. If ProcessArgs is provided, a new process will be launched. Otherwise, the debugger will try to attach to an existing process with AttachPid.

type Debugger 

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

Debugger service.

Debugger provides a higher level of abstraction over proc.Process. It handles converting from internal types to the types expected by clients. It also handles functionality needed by clients, but not needed in lower lever packages such as proc.

func (d *Debugger) EvalVariableInScope(scope api.EvalScope, symbol string, cfg proc.LoadConfig) (*api.Variable, error)

EvalVariableInScope will attempt to evaluate the variable represented by 'symbol' in the scope provided.

func (*Debugger) FindBreakpoint 

func (d *Debugger) FindBreakpoint(id int) *api.Breakpoint

FindBreakpoint returns the breakpoint specified by 'id'.

func (*Debugger) FindBreakpointByName

FindThread returns the thread for the given 'id'.

func (*Debugger) FunctionArguments 

func (d *Debugger) FunctionArguments(scope api.EvalScope, cfg proc.LoadConfig) ([]api.Variable, error)

FunctionArguments returns the arguments to the current function.

func (*Debugger) Functions 

func (d *Debugger) Functions(filter string) ([]string, error)

Functions returns a list of functions in the target process.
