• property Debug as %Debugger.System;
System Debugger object
• property IO as %Boolean;
I/O redirection flag
• property LastError as %Integer;
Last error

Methods


• method Attach(pid As %String = "", project As Project = "") as %Status
Attach to another process having process id of pid.

Fails if already attached (use Unattach first),or if pid is invalid.

On successful completion, process is attached and a break issued. The process will be in break mode upon completion of its current operation.

• method AttachToCSP(id As %Integer, project As Project = "") as %Status
Attach to a CSP process, first you must call the GetCSPAttachID to obtain the ID to pass to this method.
• method Break() as %Boolean
Send a BREAK to the target process.

A successful return indicates the target will be in break mode on completion of the current command.

Issue IsStopped to determine if target is in break mode.

• method ClearBreakpoints() as %Boolean
• method DBGCommand(cmd As %String, IsSys As %Integer = 0) as %Boolean
Perform a debug command.
• method DisableBreakpoint(routine As %String, offset As %Integer, condition As %String = "", counter As %Integer, label As %String = "") as %Boolean
• method DisableWatchpoint(variable As %String, counter As %Integer) as %Boolean
• method Eval(expr As %String = "") as %String
Evaluate and return the value of expression expr within the target process.
• method GetCSPAttachID() as %Integer
To attach to a CSP process, first call this method which will return you a unique ID number. Then display the CSP page but add an extra parameter of 'CSPDEBUG=<ID>' for example 'http://localhost/csp/samples/loop.csp?CSPDEBUG=123456'. Then call the AttachToCSP method which will attach to the process that is running this CSP page.
• classmethod GetInfo(Job As %Integer, Pid As %Integer) as %String
Gather information about a process
• method GetOffset(ByRef RoutineName As %String, ByRef BeginCmdLine As %Integer, ByRef BeginCmdOffset As %Integer, ByRef EndCmdLine As %Integer, ByRef EndCmdOffset As %Integer, ByRef BeginArgLine As %Integer, ByRef BeginArgOffset As %Integer, ByRef EndArgLine As %Integer, ByRef EndArgOffset As %Integer, ByRef NameSpace As %String) as %Integer
Return the current location of the debugger. This includes both the command and the argument positions.
• method GetSource() as %String
Return the routine source at the current location
• method GetStack() as %String
Gets the simple stack information sent from the target.
• method GetStackId() as %String
Requests stack variable info.
• method GetValue(variable As %String = "", ByRef value As %String) as %Boolean
Gets the value of a variable.
• method Go() as %Boolean
Continue the current process
• method GoTo(tag As %String) as %Boolean
Continue the current process
• classmethod INTLine(name As %String, label As %String, line As %Integer, ByRef intname As %String, ByRef intline As %String, ByRef returntype As %Integer, pNameSpace As %String = $namespace) as %Status
Given a document name, label and line offset it returns the name and line corresponding to this in the INT code returntype values are
  • 0 - Ok
  • 1 - Line given is not mapped so returning the next mapped line as breakpoint instead
  • 2 - No mapping found at all, nothing returned
For example if you wish to find out which line is generated from class 'User.Test' in method 'MyMethod' at offset '+3' you call:
	Set sc=##class(%Studio.Debugger).INTLine("User.Test.CLS","MyMethod",3,.intname,.intline,.returntype)
type is one of 'CLS' or 'MAC' currently.
• method Interrupt() as %Boolean
Interrupt the target process. The current command will be interrupted. Execution will proceed with the next command.
• method IsStopped() as %Integer
Returns 1 if the target is stopped in break mode. 0 indicates target is still running. 2 indicates target has exited debugger or fatal error.
• method Line() as %Boolean
• method LineIn() as %Boolean
• method LineOut() as %Boolean
• classmethod MappedFromLine(rtn As %String, line As %Integer, namespace As %String, ByRef mapping As %String) as %Status
Return the list of source files that the routine and line map to. The format of each source file data is:

routineName.routineType,label,line,namespace

• classmethod MappedFromPos(routineName As %String, beginCmdLine As %Integer, beginCmdOffset As %Integer, endCmdLine As %Integer, endCmdOffset As %Integer, beginArgLine As %Integer, beginArgOffset As %Integer, endArgLine As %Integer, endArgOffset As %Integer, namespace As %String, ByRef mapping As %String, ByRef flag As %String) as %Status
Return the list of source files that the position passed in maps to. Each source file is separated by a space character. The format of each source file data is:

routineName,label,beginCmdLine,beginCmdOffset,endCmdLine,endCmdOffset,beginArgLine,beginArgOffset,endArgLine,endArgOffset,Namespace

• method MappedOffset(ByRef mapping As %String, ByRef namespace As %String, ByRef flag As %String) as %Status
Return the list of source files that the current break point maps to starting with the INT/BAS routine. Each source file is separated by a space character. The format of each source file data is:

routineName,label,beginCmdLine,beginCmdOffset,endCmdLine,endCmdOffset,beginArgLine,beginArgOffset,endArgLine,endArgOffset,Namespace

Given INT routine name and line number and offset in this line return an array of source lines that map to this INT line. The format of this return array is:

map(type,StartEnd)=$listbuild(sourceName,sourceLabel,sourceLine,Offset,Namespace)

Where StartEnd is 1 for the start of the map and 2 for the end, sourceName is the name of the source file, sourceLabel is the method/label name, sourceLine is the number of lines from this label to the location, Offset is the offset on the line, Namespace is the location of the source file.
