TDebuggerIntf

TDebuggerIntf is the base class of implementing a debugger as Lazarus-IDE plugin package. The package must have DebuggerIntf package as it's requirements. Any debugger plug-in must implement the class and register via RegisterDebugger (called at Register of registering unit).

Minimal Implementation

The following methods must be implemented for TDebbugerIntf

• GetSupportedCommands - returns the set of formats that a debugger can perform
• RequestCommand - the method actually performing commands. Only commands returned by GetSupportedCommands would be passed to this method
• Caption - the method return user-friendly name of the debugger

Methods

RequestCommand

The method should return false, if the command cannot be executed.

Development Hints

• it might be helpful to rebuild IDE adding the following defines into build Options:

-dVerboseDebugger - VerboseDebugger logs messages debugging calls from IDE itself

-dDBG_STATE - states changes in TDebuggerIntf

-dDBG_EVENTS - events in TDebuggerIntf

-dDBG_VERBOSE - additional information in TDebuggerIntf

-dDBG_WARNINGS - warnings information in TDebuggerIntf

-dDBG_DATA_MONITORS -

-dDBG_DISASSEMBLER -

so the all the steps of IDE attempting to call a debugger would be logged.
