Debug Adapter Protocol

The Debug Adapter Protocol defines the protocol used between an editor or IDE and a debugger or runtime.

A machine-readable JSON schema can be foundhere.

The change history of the specification liveshere.

Base Protocol

ProtocolMessage

Base class of requests, responses, and events.

interfaceProtocolMessage{/**   * Sequence number of the message (also known as message ID). The `seq` for   * the first message sent by a client or debug adapter is 1, and for each   * subsequent message is 1 greater than the previous message sent by that   * actor. `seq` can be used to order requests, responses, and events, and to   * associate requests with their corresponding responses. For protocol   * messages of type `request` the sequence number can be used to cancel the   * request.   */seq:number;/**   * Message type.   * Values: 'request', 'response', 'event', etc.   */type:'request'|'response'|'event'|string;}

Request

A client or debug adapter initiated request.

interfaceRequestextendsProtocolMessage{type:'request';/**   * The command to execute.   */command:string;/**   * Object containing arguments for the command.   */arguments?:any;}

Event

A debug adapter initiated event.

interfaceEventextendsProtocolMessage{type:'event';/**   * Type of event.   */event:string;/**   * Event-specific information.   */body?:any;}

Response

Response for a request.

interfaceResponseextendsProtocolMessage{type:'response';/**   * Sequence number of the corresponding request.   */request_seq:number;/**   * Outcome of the request.   * If true, the request was successful and the `body` attribute may contain   * the result of the request.   * If the value is false, the attribute `message` contains the error in short   * form and the `body` may contain additional information (see   * `ErrorResponse.body.error`).   */success:boolean;/**   * The command requested.   */command:string;/**   * Contains the raw error in short form if `success` is false.   * This raw error might be interpreted by the client and is not shown in the   * UI.   * Some predefined values exist.   * Values:   * 'cancelled': the request was cancelled.   * 'notStopped': the request may be retried once the adapter is in a 'stopped'   * state.   * etc.   */message?:'cancelled'|'notStopped'|string;/**   * Contains request result if success is true and error details if success is   * false.   */body?:any;}

ErrorResponse

On error (wheneversuccess is false), the body can provide more details.

interfaceErrorResponseextendsResponse{body:{/**     * A structured error message.     */error?:Message;};}

Cancel Request

Thecancel request is used by the client in two situations:

to indicate that it is no longer interested in the result produced by a specific request issued earlier
to cancel a progress sequence.

Clients should only call this request if the corresponding capabilitysupportsCancelRequest is true.

This request has a hint characteristic: a debug adapter can only be expected to make a ‘best effort’ in honoring this request but there are no guarantees.

Thecancel request may return an error if it could not cancel an operation but a client should refrain from presenting this error to end users.

The request that got cancelled still needs to send a response back. This can either be a normal result (success attribute true) or an error response (success attribute false and themessage set tocancelled).

Returning partial results from a cancelled request is possible but please note that a client has no generic way for detecting that a response is partial or not.

The progress that got cancelled still needs to send aprogressEnd event back.

A client should not assume that progress just got cancelled after sending thecancel request.

interfaceCancelRequestextendsRequest{command:'cancel';arguments?:CancelArguments;}

Arguments forcancel request.

interfaceCancelArguments{/**   * The ID (attribute `seq`) of the request to cancel. If missing no request is   * cancelled.   * Both a `requestId` and a `progressId` can be specified in one request.   */requestId?:number;/**   * The ID (attribute `progressId`) of the progress to cancel. If missing no   * progress is cancelled.   * Both a `requestId` and a `progressId` can be specified in one request.   */progressId?:string;}

Response tocancel request. This is just an acknowledgement, so no body field is required.

interfaceCancelResponseextendsResponse{}

Events

Initialized Event

This event indicates that the debug adapter is ready to accept configuration requests (e.g.setBreakpoints,setExceptionBreakpoints).

A debug adapter is expected to send this event when it is ready to accept configuration requests (but not before theinitialize request has finished).

The sequence of events/requests is as follows:

adapters sendsinitialized event (after theinitialize request has returned)
client sends zero or moresetBreakpoints requests
client sends onesetFunctionBreakpoints request (if corresponding capabilitysupportsFunctionBreakpoints is true)
client sends asetExceptionBreakpoints request if one or moreexceptionBreakpointFilters have been defined (or ifsupportsConfigurationDoneRequest is not true)
client sends other future configuration requests
client sends oneconfigurationDone request to indicate the end of the configuration.

interfaceInitializedEventextendsEvent{event:'initialized';}

Stopped Event

The event indicates that the execution of the debuggee has stopped due to some condition.

This can be caused by a breakpoint previously set, a stepping request has completed, by executing a debugger statement etc.

interfaceStoppedEventextendsEvent{event:'stopped';body:{/**     * The reason for the event.     * For backward compatibility this string is shown in the UI if the     * `description` attribute is missing (but it must not be translated).     * Values: 'step', 'breakpoint', 'exception', 'pause', 'entry', 'goto',     * 'function breakpoint', 'data breakpoint', 'instruction breakpoint', etc.     */reason:'step'|'breakpoint'|'exception'|'pause'|'entry'|'goto'|'function breakpoint'|'data breakpoint'|'instruction breakpoint'|string;/**     * The full reason for the event, e.g. 'Paused on exception'.

E.g. if reason is `exception`, text contains the     * exception name. This string is shown in the UI.     */text?:string;/**     * If `allThreadsStopped` is true, a debug adapter can announce that all     * threads have stopped.     * - The client should use this information to enable that all threads can     * be expanded to access their stacktraces.     * - If the attribute is missing or false, only the thread with the given     * `threadId` can be expanded.     */allThreadsStopped?:boolean;/**     * Ids of the breakpoints that triggered the event. In most cases there is     * only a single breakpoint but here are some examples for multiple     * breakpoints:     * - Different types of breakpoints map to the same location.     * - Multiple source breakpoints get collapsed to the same instruction by     * the compiler/runtime.     * - Multiple function breakpoints with different function names map to the     * same location.     */hitBreakpointIds?:number[];};}

Continued Event

The event indicates that the execution of the debuggee has continued.

Please note: a debug adapter is not expected to send this event in response to a request that implies that execution continues, e.g.launch orcontinue.

It is only necessary to send acontinued event if there was no previous request that implied this.

interfaceContinuedEventextendsEvent{event:'continued';body:{/**     * The thread which was continued.     */threadId:number;/**     * If omitted or set to `true`, this event signals to the client that all     * threads have been resumed. The value `false` indicates that not all     * threads were resumed.     */allThreadsContinued?:boolean;};}

Exited Event

The event indicates that the debuggee has exited and returns its exit code.

interfaceExitedEventextendsEvent{event:'exited';body:{/**     * The exit code returned from the debuggee.     */exitCode:number;};}

Terminated Event

The event indicates that debugging of the debuggee has terminated. This doesnot mean that the debuggee itself has exited.

interfaceTerminatedEventextendsEvent{event:'terminated';body?:{/**     * A debug adapter may set `restart` to true (or to an arbitrary object) to     * request that the client restarts the session.     * The value is not interpreted by the client and passed unmodified as an     * attribute `__restart` to the `launch` and `attach` requests.     */restart?:any;};}

Thread Event

The event indicates that a thread has started or exited.

interfaceThreadEventextendsEvent{event:'thread';body:{/**     * The reason for the event.     * Values: 'started', 'exited', etc.     */reason:'started'|'exited'|string;/**     * The identifier of the thread.     */threadId:number;};}

Output Event

The event indicates that the target has produced some output.

interfaceOutputEventextendsEvent{event:'output';body:{/**     * The output category. If not specified or if the category is not     * understood by the client, `console` is assumed.     * Values:     * 'console': Show the output in the client's default message UI, e.g. a     * 'debug console'.

See     * 'Lifetime of Object References' in the Overview section for details.     */locationReference?:number;};}

Breakpoint Event

The event indicates that some information about a breakpoint has changed.

interfaceBreakpointEventextendsEvent{event:'breakpoint';body:{/**     * The reason for the event.     * Values: 'changed', 'new', 'removed', etc.     */reason:'changed'|'new'|'removed'|string;/**     * The `id` attribute is used to find the target breakpoint, the other     * attributes are used as the new values.     */breakpoint:Breakpoint;};}

Module Event

The event indicates that some information about a module has changed.

interfaceModuleEventextendsEvent{event:'module';body:{/**     * The reason for the event.     * Values: 'new', 'changed', 'removed'     */reason:'new'|'changed'|'removed';/**     * The new, changed, or removed module. In case of `removed` only the module     * id is used.     */module:Module;};}

LoadedSource Event

The event indicates that some source has been added, changed, or removed from the set of all loaded sources.

interfaceLoadedSourceEventextendsEvent{event:'loadedSource';body:{/**     * The reason for the event.     * Values: 'new', 'changed', 'removed'     */reason:'new'|'changed'|'removed';/**     * The new, changed, or removed source.     */source:Source;};}

Process Event

The event indicates that the debugger has begun debugging a new process. Either one that it has launched, or one that it has attached to.

interfaceProcessEventextendsEvent{event:'process';body:{/**     * The logical name of the process. This is usually the full path to     * process's executable file. Example: /home/example/myproj/program.js.     */name:string;/**     * The process ID of the debugged process, as assigned by the operating     * system.

This value     * may be used by clients when formatting addresses for display.     */pointerSize?:number;};}

Capabilities Event

The event indicates that one or more capabilities have changed.

Since the capabilities are dependent on the client and its UI, it might not be possible to change that at random times (or too late).

Consequently this event has a hint characteristic: a client can only be expected to make a ‘best effort’ in honoring individual capabilities but there are no guarantees.

Only changed capabilities need to be included, all other capabilities keep their values.

interfaceCapabilitiesEventextendsEvent{event:'capabilities';body:{/**     * The set of updated capabilities.     */capabilities:Capabilities;};}

ProgressStart Event

The event signals that a long running operation is about to start and provides additional information for the client to set up a corresponding progress and cancellation UI.

The client is free to delay the showing of the UI in order to reduce flicker.

This event should only be sent if the corresponding capabilitysupportsProgressReporting is true.

interfaceProgressStartEventextendsEvent{event:'progressStart';body:{/**     * An ID that can be used in subsequent `progressUpdate` and `progressEnd`     * events to make them refer to the same progress reporting.     * IDs must be unique within a debug session.     */progressId:string;/**     * Short title of the progress reporting. Shown in the UI to describe the     * long running operation.     */title:string;/**     * The request ID that this progress report is related to. If specified a     * debug adapter is expected to emit progress events for the long running     * request until the request has been either completed or cancelled.     * If the request ID is omitted, the progress report is assumed to be     * related to some general activity of the debug adapter.     */requestId?:number;/**     * If true, the request that reports progress may be cancelled with a     * `cancel` request.     * So this property basically controls whether the client should use UX that     * supports cancellation.     * Clients that don't support cancellation are allowed to ignore the     * setting.     */cancellable?:boolean;/**     * More detailed progress message.     */message?:string;/**     * Progress percentage to display (value range: 0 to 100). If omitted no     * percentage is shown.     */percentage?:number;};}

ProgressUpdate Event

The event signals that the progress reporting needs to be updated with a new message and/or percentage.

The client does not have to update the UI immediately, but the clients needs to keep track of the message and/or percentage values.

This event should only be sent if the corresponding capabilitysupportsProgressReporting is true.

interfaceProgressUpdateEventextendsEvent{event:'progressUpdate';body:{/**     * The ID that was introduced in the initial `progressStart` event.     */progressId:string;/**     * More detailed progress message. If omitted, the previous message (if any)     * is used.     */message?:string;/**     * Progress percentage to display (value range: 0 to 100). If omitted no     * percentage is shown.     */percentage?:number;};}

ProgressEnd Event

The event signals the end of the progress reporting with a final message.

This event should only be sent if the corresponding capabilitysupportsProgressReporting is true.

interfaceProgressEndEventextendsEvent{event:'progressEnd';body:{/**     * The ID that was introduced in the initial `ProgressStartEvent`.     */progressId:string;/**     * More detailed progress message. If omitted, the previous message (if any)     * is used.     */message?:string;};}

Invalidated Event

This event signals that some state in the debug adapter has changed and requires that the client needs to re-render the data snapshot previously requested.

Debug adapters do not have to emit this event for runtime changes like stopped or thread events because in that case the client refetches the new state anyway. But the event can be used for example to refresh the UI after rendering formatting has changed in the debug adapter.

This event should only be sent if the corresponding capabilitysupportsInvalidatedEvent is true.

interfaceInvalidatedEventextendsEvent{event:'invalidated';body:{/**     * Set of logical areas that got invalidated. This property has a hint     * characteristic: a client can only be expected to make a 'best effort' in     * honoring the areas but there are no guarantees. If this property is     * missing, empty, or if values are not understood, the client should assume     * a single value `all`.     */areas?:InvalidatedAreas[];/**     * If specified, the client only needs to refetch data related to this     * thread.     */threadId?:number;/**     * If specified, the client only needs to refetch data related to this stack     * frame (and the `threadId` is ignored).     */stackFrameId?:number;};}

Memory Event

This event indicates that some memory range has been updated. It should only be sent if the corresponding capabilitysupportsMemoryEvent is true.

Clients typically react to the event by re-issuing areadMemory request if they show the memory identified by thememoryReference and if the updated memory range overlaps the displayed range. Clients should not make assumptions how individual memory references relate to each other, so they should not assume that they are part of a single continuous address range and might overlap.

Debug adapters can use this event to indicate that the contents of a memory range has changed due to some other request likesetVariable orsetExpression. Debug adapters are not expected to emit this event for each and every memory change of a running program, because that information is typically not available from debuggers and it would flood clients with too many events.

interfaceMemoryEventextendsEvent{event:'memory';body:{/**     * Memory reference of a memory range that has been updated.     */memoryReference:string;/**     * Starting offset in bytes where memory has been updated. Can be negative.     */offset:number;/**     * Number of bytes updated.     */count:number;};}

Reverse Requests

RunInTerminal Request

This request is sent from the debug adapter to the client to run a command in a terminal.

This is typically used to launch the debuggee in a terminal provided by the client.

This request should only be called if the corresponding client capabilitysupportsRunInTerminalRequest is true.

Client implementations ofrunInTerminal are free to run the command however they choose including issuing the command to a command line interpreter (aka ‘shell’). Argument strings passed to therunInTerminal request must arrive verbatim in the command to be run. As a consequence, clients which use a shell are responsible for escaping any special shell characters in the argument strings to prevent them from being interpreted (and modified) by the shell.

Some users may wish to take advantage of shell processing in the argument strings. For clients which implementrunInTerminal using an intermediary shell, theargsCanBeInterpretedByShell property can be set to true. In this case the client is requested not to escape any special shell characters in the argument strings.

interfaceRunInTerminalRequestextendsRequest{command:'runInTerminal';arguments:RunInTerminalRequestArguments;}

Arguments forrunInTerminal request.

interfaceRunInTerminalRequestArguments{/**   * What kind of terminal to launch. Defaults to `integrated` if not specified.   * Values: 'integrated', 'external'   */kind?:'integrated'|'external';/**   * Title of the terminal.   */title?:string;/**   * Working directory for the command. For non-empty, valid paths this   * typically results in execution of a change directory command.   */cwd:string;/**   * List of arguments. The first argument is the command to run.   */args:string[];/**   * Environment key-value pairs that are added to or removed from the default   * environment.   */env?:{[key:string]:string|null;};/**   * This property should only be set if the corresponding capability   * `supportsArgsCanBeInterpretedByShell` is true. If the client uses an   * intermediary shell to launch the application, then the client must not   * attempt to escape characters with special meanings for the shell. The user   * is fully responsible for escaping as needed and that arguments using   * special characters may not be portable across shells.   */argsCanBeInterpretedByShell?:boolean;}

Response torunInTerminal request.

interfaceRunInTerminalResponseextendsResponse{body:{/**     * The process ID. The value should be less than or equal to 2147483647     * (2^31-1).     */processId?:number;/**     * The process ID of the terminal shell. The value should be less than or     * equal to 2147483647 (2^31-1).     */shellProcessId?:number;};}

StartDebugging Request

This request is sent from the debug adapter to the client to start a new debug session of the same type as the caller.

This request should only be sent if the corresponding client capabilitysupportsStartDebuggingRequest is true.

A client implementation ofstartDebugging should start a new debug session (of the same type as the caller) in the same way that the caller’s session was started. If the client supports hierarchical debug sessions, the newly created session can be treated as a child of the caller session.

interfaceStartDebuggingRequestextendsRequest{command:'startDebugging';arguments:StartDebuggingRequestArguments;}

Arguments forstartDebugging request.

interfaceStartDebuggingRequestArguments{/**   * Arguments passed to the new debug session. The arguments must only contain   * properties understood by the `launch` or `attach` requests of the debug   * adapter and they must not contain any client-specific properties (e.g.   * `type`) or client-specific features (e.g. substitutable 'variables').   */configuration:{[key:string]:any;};/**   * Indicates whether the new debug session should be started with a `launch`   * or `attach` request.   * Values: 'launch', 'attach'   */request:'launch'|'attach';}

Response tostartDebugging request. This is just an acknowledgement, so no body field is required.

interfaceStartDebuggingResponseextendsResponse{}

Requests

Initialize Request

Theinitialize request is sent as the first request from the client to the debug adapter in order to configure it with client capabilities and to retrieve capabilities from the debug adapter.

Until the debug adapter has responded with aninitialize response, the client must not send any additional requests or events to the debug adapter.

In addition the debug adapter is not allowed to send any requests or events to the client until it has responded with aninitialize response.

Theinitialize request may only be sent once.

interfaceInitializeRequestextendsRequest{command:'initialize';arguments:InitializeRequestArguments;}

Arguments forinitialize request.

interfaceInitializeRequestArguments{/**   * The ID of the client using this adapter.   */clientID?:string;/**   * The human-readable name of the client using this adapter.   */clientName?:string;/**   * The ID of the debug adapter.   */adapterID:string;/**   * The ISO-639 locale of the client using this adapter, e.g. en-US or de-CH.   */locale?:string;/**   * If true all line numbers are 1-based (default).   */linesStartAt1?:boolean;/**   * If true all column numbers are 1-based (default).   */columnsStartAt1?:boolean;/**   * Determines in what format paths are specified.

Response toinitialize request.

interfaceInitializeResponseextendsResponse{/**   * The capabilities of this debug adapter.   */body?:Capabilities;}

ConfigurationDone Request

This request indicates that the client has finished initialization of the debug adapter.

So it is the last request in the sequence of configuration requests (which was started by theinitialized event).

Clients should only call this request if the corresponding capabilitysupportsConfigurationDoneRequest is true.

interfaceConfigurationDoneRequestextendsRequest{command:'configurationDone';arguments?:ConfigurationDoneArguments;}

Arguments forconfigurationDone request.

interfaceConfigurationDoneArguments{}

Response toconfigurationDone request. This is just an acknowledgement, so no body field is required.

interfaceConfigurationDoneResponseextendsResponse{}

Launch Request

This launch request is sent from the client to the debug adapter to start the debuggee with or without debugging (ifnoDebug is true).

Since launching is debugger/runtime specific, the arguments for this request are not part of this specification.

interfaceLaunchRequestextendsRequest{command:'launch';arguments:LaunchRequestArguments;}

Arguments forlaunch request. Additional attributes are implementation specific.

interfaceLaunchRequestArguments{/**   * If true, the launch request should launch the program without enabling   * debugging.   */noDebug?:boolean;/**   * Arbitrary data from the previous, restarted session.   * The data is sent as the `restart` attribute of the `terminated` event.   * The client should leave the data intact.   */__restart?:any;}

Response tolaunch request. This is just an acknowledgement, so no body field is required.

interfaceLaunchResponseextendsResponse{}

Attach Request

Theattach request is sent from the client to the debug adapter to attach to a debuggee that is already running.

Since attaching is debugger/runtime specific, the arguments for this request are not part of this specification.

interfaceAttachRequestextendsRequest{command:'attach';arguments:AttachRequestArguments;}

Arguments forattach request. Additional attributes are implementation specific.

interfaceAttachRequestArguments{/**   * Arbitrary data from the previous, restarted session.   * The data is sent as the `restart` attribute of the `terminated` event.   * The client should leave the data intact.   */__restart?:any;}

Response toattach request. This is just an acknowledgement, so no body field is required.

interfaceAttachResponseextendsResponse{}

Restart Request

Restarts a debug session. Clients should only call this request if the corresponding capabilitysupportsRestartRequest is true.

If the capability is missing or has the value false, a typical client emulatesrestart by terminating the debug adapter first and then launching it anew.

interfaceRestartRequestextendsRequest{command:'restart';arguments?:RestartArguments;}

Arguments forrestart request.

interfaceRestartArguments{/**   * The latest version of the `launch` or `attach` configuration.   */arguments?:LaunchRequestArguments|AttachRequestArguments;}

Response torestart request. This is just an acknowledgement, so no body field is required.

interfaceRestartResponseextendsResponse{}

Disconnect Request

Thedisconnect request asks the debug adapter to disconnect from the debuggee (thus ending the debug session) and then to shut down itself (the debug adapter).

In addition, the debug adapter must terminate the debuggee if it was started with thelaunch request. If anattach request was used to connect to the debuggee, then the debug adapter must not terminate the debuggee.

This implicit behavior of when to terminate the debuggee can be overridden with theterminateDebuggee argument (which is only supported by a debug adapter if the corresponding capabilitysupportTerminateDebuggee is true).

Terminate Request

Theterminate request is sent from the client to the debug adapter in order to shut down the debuggee gracefully. Clients should only call this request if the capabilitysupportsTerminateRequest is true.

Typically a debug adapter implementsterminate by sending a software signal which the debuggee intercepts in order to clean things up properly before terminating itself.

Please note that this request does not directly affect the state of the debug session: if the debuggee decides to veto the graceful shutdown for any reason by not terminating itself, then the debug session just continues.

Clients can surface theterminate request as an explicit command or they can integrate it into a two stage Stop command that first sendsterminate to request a graceful shutdown, and if that fails usesdisconnect for a forceful shutdown.

SetExceptionBreakpoints Request

The request configures the debugger’s response to thrown exceptions. Each of thefilters,filterOptions, andexceptionOptions in the request are independent configurations to a debug adapter indicating a kind of exception to catch.

Response tosetExceptionBreakpoints request.

The response contains an array ofBreakpoint objects with information about each exception breakpoint or filter. TheBreakpoint objects are in the same order as the elements of thefilters,filterOptions,exceptionOptions arrays given as arguments. If bothfilters andfilterOptions are given, the returned array must start withfilters information first, followed byfilterOptions information.

Theverified property of aBreakpoint object signals whether the exception breakpoint or filter could be successfully created and whether the condition is valid. In case of an error themessage property explains the problem. Theid property can be used to introduce a unique ID for the exception breakpoint or filter so that it can be updated subsequently by sending breakpoint events.

For backward compatibility both thebreakpoints array and the enclosingbody are optional. If these elements are missing a client is not able to show problems for individual exception breakpoints or filters.

interfaceSetExceptionBreakpointsResponseextendsResponse{body?:{/**     * Information about the exception breakpoints or filters.     * The breakpoints returned are in the same order as the elements of the     * `filters`, `filterOptions`, `exceptionOptions` arrays in the arguments.     * If both `filters` and `filterOptions` are given, the returned array must     * start with `filters` information first, followed by `filterOptions`     * information.     */breakpoints?:Breakpoint[];};}

ExceptionBreakpointsFilter

AnExceptionBreakpointsFilter is shown in the UI as an filter option for configuring how exceptions are dealt with.

interfaceExceptionBreakpointsFilter{/**   * The internal ID of the filter option.

Message

A structured message object. Used to return errors from requests.

interfaceMessage{/**   * Unique (within a debug adapter implementation) identifier for the message.   * The purpose of these error IDs is to help extension authors that have the   * requirement that every user visible error message needs a corresponding   * error number, so that users or customer support can find information about   * the specific error more easily.   */id:number;/**   * A format string for the message.

Module

A Module object represents a row in the modules view.

Theid attribute identifies a module in the modules view and is used in amodule event for identifying a module for adding, updating or deleting.

Thename attribute is used to minimally render the module in the UI.

Additional attributes can be added to the module. They show up in the module view if they have a correspondingColumnDescriptor.

To avoid an unnecessary proliferation of additional attributes with similar semantics but different names, we recommend to re-use attributes from the ‘recommended’ list below first, and only introduce new attributes if nothing appropriate could be found.

interfaceModule{/**   * Unique identifier for the module.   */id:number|string;/**   * A name of the module.   */name:string;/**   * Logical full path to the module. The exact definition is implementation   * defined, but usually this would be a full path to the on-disk file for the   * module.   */path?:string;/**   * True if the module is optimized.   */isOptimized?:boolean;/**   * True if the module is considered 'user code' by a debugger that supports   * 'Just My Code'.   */isUserCode?:boolean;/**   * Version of Module.   */version?:string;/**   * User-understandable description of if symbols were found for the module   * (ex: 'Symbols Loaded', 'Symbols not found', etc.)   */symbolStatus?:string;/**   * Logical full path to the symbol file.

ColumnDescriptor

AColumnDescriptor specifies what module attribute to show in a column of the modules view, how to format it,

and what the column’s label should be.

It is only used if the underlying UI actually supports this level of customization.

interfaceColumnDescriptor{/**   * Name of the attribute rendered in this column.   */attributeName:string;/**   * Header UI label of column.   */label:string;/**   * Format to use for the rendered values in this column. TBD how the format   * strings looks like.   */format?:string;/**   * Datatype of values in this column. Defaults to `string` if not specified.   * Values: 'string', 'number', 'boolean', 'unixTimestampUTC'   */type?:'string'|'number'|'boolean'|'unixTimestampUTC';/**   * Width of this column in characters (hint only).   */width?:number;}

Thread

A Thread

interfaceThread{/**   * Unique identifier for the thread.   */id:number;/**   * The name of the thread.   */name:string;}

Source

ASource is a descriptor for source code.

It is returned from the debug adapter as part of aStackFrame and it is used by clients when specifying breakpoints.

Every source returned from the debug adapter   * has a name.   * When sending a source to the debug adapter this name is optional.   */name?:string;/**   * The path of the source to be shown in the UI.   * It is only used to locate and load the content of the source if no   * `sourceReference` is specified (or its value is 0).   */path?:string;/**   * If the value > 0 the contents of the source must be retrieved through the   * `source` request (even if a path is specified).   * Since a `sourceReference` is only valid for a session, it can not be used   * to persist a source.   * The value should be less than or equal to 2147483647 (2^31-1).   */sourceReference?:number;/**   * A hint for how to present the source in the UI.   * A value of `deemphasize` can be used to indicate that the source is not   * available or that it is skipped on stepping.   * Values: 'normal', 'emphasize', 'deemphasize'   */presentationHint?:'normal'|'emphasize'|'deemphasize';/**   * The origin of this source. For example, 'internal module', 'inlined content   * from source map', etc.   */origin?:string;/**   * A list of sources that are related to this source. These may be the source   * that generated this source.   */sources?:Source[];/**   * Additional data that a debug adapter might want to loop through the client.   * The client should leave the data intact and persist it across sessions. The   * client should not interpret the data.   */adapterData?:any;/**   * The checksums associated with this file.   */checksums?:Checksum[];}

StackFrame

A Stackframe contains the source location.

interfaceStackFrame{/**   * An identifier for the stack frame.

Variable

A Variable is a name/value pair.

Thetype attribute is shown if space permits or when hovering over the variable’s name.

Thekind attribute is used to render additional properties of the variable, e.g. different icons can be used to indicate that a variable is public or private.

If the value is structured (has children), a handle is provided to retrieve the children with thevariables request.

If the number of named or indexed children is large, the numbers should be returned via thenamedVariables andindexedVariables attributes.

The client can use this information to present the children in a paged UI and fetch them in chunks.
