- A native language client framework (Dotnet, Java, Javascript, C++ , Python, Delphi) to send simple traces, class and object viewer, dump, and call stack to the viewer. See Working with the viewer for user interface
Download the Viewer and unpack the file into a folder of your chose (windows only).
If you plan to use the "windows message" mode, you must start once the viewer to self register his location into the registry. For socket mode, the viewer must always be started manually
When the viewer is started, he appears on the tray icon. Closing the viewer just reduce it to systray.
Hit ctrl - Alt - X to close it.
You can chose the protocol to send traces to the viewer.
- Socket connection (localhost or remote). This is the prefered mode for many languages. Don't work for javascript / TypeScript and node
- Windows message (same computer). Don't work with Java, javascript / TypeScript, node and python
- Web socket connection. Work only with dotnet (blazor client)
- Http connection. Work only with javascript / Typescript
Demo is provided for each client api \
Blazor client support only Synchronous communication (Web socket connection)
Note for Web socket connection: The viewer use a plugin to receive traces and display on the viewer.
The plugin is configured, but not activated by default.
Update the path to the WebsockPlugin.dll (require dotnet 4.8)
The following parameter tell the plugin to receive from web socket 0.0.0.0 on port 8091 and resend the trace to itself on port 8090
WebSocketHost = 0.0.0.0, WebSocketPort = 8091, ViewerSocketHost = 127.0.0.1, ViewerSocketPort = 8090
On the view menu, select options... item, click on "WebsockPlugin.dll" item, click "Load at startup",
click "Load and start" button then "Ok" button.
The "web socket" label is displayed in the trace window. Clicking on this label show some statistics informations
In visual studio, reference the client Api nuget using "manage nuget packages","Manage Nuget Packages for solution" context menus or via the nuget console
Install-Package Tracetool.DotNet.Api
The nuget contains DotNet4.8 and Standard 2.0 libraries
Sample code
using TraceTool ;
...
TTrace.Error.Send("Hello world") ; // one columns
TTrace.Warning.Send("Hello","world") ; // two columns
TTrace.Debug.Send("Hello").Send("world") ; // 2 nodes (master detail)Here is the result:
If you chose socket mode (web development, service,...), add this code to your startup function
using TraceTool ;
...
TTrace.Options.SendMode = SendMode.Socket;
TTrace.Options.SocketHost = "127.0.0.1";
TTrace.Options.SocketPort = 8090;See the Samples section for more examples
You can use tracetool on client site. Add a reference to Tracetool.DotNet.Api, specify websocket mode and async communication.
Don't forget to enable plugin !
Here is a simple razor page
@page "/"
@using TraceTool
<h1>tracetool demo</h1>
<button class="btn btn-primary" @onclick="SimpleTraces">trace tool demo</button>
@code {
protected override void OnInitialized()
{
TTrace.Options.SendMode = SendMode.WebSocket;
TTrace.Options.UseWorkerThread = false; // Async communication for blazor client
TTrace.Options.SocketHost = "127.0.0.1";
TTrace.Options.SocketPort = 8091;
}
private async void SimpleTraces()
{
TTrace.Debug.Send($"trace from blazor client");
TTrace.Debug.SendValue("Value", TTrace.Debug);
TTrace.Debug.SendObject("Object", TTrace.Debug);
// not necessary to flush. If you don't need to wait for traces, just remove the "async" before SimpleTraces()
await TTrace.FlushAsync(); // wait for all message send
}Here is the result:
See the Samples section for more examples
Download the Tracetool.jar from github
Sample code
import TraceTool.*;
...
TTrace.Warning().Send("hello" , "world");See the Samples section for more examples
This is a special version of the Java library with some implementation differences (GUID, color, connection). The library can send traces to the viewer through Wi-Fi, 3G, or USB. Both real device and Android Virtual Device (AVD in short) are supported.
Open the 8090 port on your firewall. Run your application, and set TTrace.options.socketHost to your development computer IP address Send traces.
The TraceTool API is a cross browser (tested under Internet Explorer ,chrome, Firefox) and cross domain tracing solution. The viewer can be installed on any PC (localhost, for example) while you are displaying a page from another server. Just configure the TraceTool JavaScript client to use the viewer on the network. you can use tracetool in html (angular for example)
Javascript files (tracetool.js)
and (tracetool.jmin.js) are included in the viewer folder.
You can also install it from Npm command line:
npm install -s tracetool
The node package contains typings tracetool.d.ts for typescript
Html sample code
...
<script type="text/javascript" src="tracetool.js" no-cache></script>
...
<script>
ttrace.host="localHost:85";
function butSample()
{
ttrace.debug.send('hello world') ;
ttrace.debug.send('hello','world') ;
var hello = ttrace.debug.send('hello') ;
hello.send('world') ; // send traces under another node
} ;
</script>
...
<input type="button" value="Sample traces" onclick="butSample()"/>Another way to load the library is to ask the viewer to send the script. Add this line on the body tag:
<script type="text/JavaScript"
src="http://localHost:81/tracetool.js?Compressed=true" no-cache>
</script>Angular sample code
package.json -> "dependencies" -> "@tracetool/webpack": "^1.0.1"
app.component.ts
import '@tracetool/webpack'; // import once. ttrace is saved in global
ttrace.host = "127.0.0.1:85"; // Must be done once
...
ngOnInit(): void {
ttrace.debug.send("Hello", "world");
}Node js sample code
package.json -> "dependencies" -> "tracetool": ">12.10.2"
example.js
"use strict";
const ttrace = require('tracetool'); // default host is 127.0.0.1:81
ttrace.host = "127.0.0.1:85";
ttrace.debug.send("Hello", "world");See the Samples section for more examples
For managed code, use the dotnet library
Unmanaged C++ files (tracetool.cpp) and (tracetool.h) are included in the Cpp/Source folder.
Unmanaged code sample:
#include "tracetool.h"
...
TTrace::Debug()->Send ("Hello");See the Samples section for more examples
Python file (tracetool.py)
is included in the Python/Src folder.
Alternatively, your can install the library using the pip command (windows or lunix command line)
pip install --upgrade tracetoolThe library is compatible with Python 2, Python 3, and Iron Python (.NET). Also tested under Blender
Sample code
>>> from tracetool import ttrace
>>> ttrace.debug.send ("hello Python")Delphi files are included in the Delphi/Delphi Library folder
Sample code
uses TraceTool,
...
TTrace.Warning.Send('hello' , 'world') ;ActiveX files (ActiveX_Lib.zip) are included in the ActiveX/Lib folder. The zip file contains batch file to register the library on the registry
Sample code (JScript):
var TTrace = new ActiveXObject("TraceToolCom.XTrace");
...
TTrace.Debug.Send("hello from jScript") ;
For facility, all samples uses the DOTNET syntax. Note that not all client framework support all functionalities like sending image to viewer with Python
// 90 % of your traces will be just sending a single string or 2 strings on a single line
TTrace.Debug.Send("simple node");
TTrace.Debug.Send("my string", "my value");
// Master detail node
TTrace.Debug.Send("master").Send("Detail");
var masterNode = TTrace.Debug.Send("master");
masterNode.Send("Detail 1");
masterNode.Send("Detail 2");Another way to have master detail is to use Indent and UnIndent methods. Important Note, since the version 14, the Dotnet api introduce a breaking change: When async operations are used together with TTrace.Send() methods, the traces stays under the parent nodes. The ThiId column will show the new thread Id after async operations
TTrace.Debug.Indent ("Begin of procedure") ;
TTrace.Debug.Send ("inside procedure" ) ;
await Task.Delay(500);
TTrace.Debug.Send ("Do some work" ) ;
TTrace.Debug.UnIndent ("end of procedure") ;
Note : ensure the UnIndent is called (use try finally), else you will see unexpected indentation
Once a node is sent, you have the possibility to change the text. For example, send the "Start.." text, and when an operation is completed, append the "Done" text, or replace one of the two columns with a new text:
TraceNode start1 = TTrace.Debug.Send ("Start 1 ..") ;
start1.ResendRight ("Done") ;
TraceNode start2 = TTrace.Debug.Send ("Start 2 ..") ;
start2.AppendLeft ("Done") ;
Note that the time is not changed.
You can send traces in a separate window tab:
WinTrace myWinTrace ;
myWinTrace = new WinTrace ("MyWINID", "My trace window");
myWinTrace.Debug.Send ("Hello", "Can be used to store exceptions, for examples");You can access the main WinTrace objects from the TTrace.WinTrace attribute.
The WinTrace API lets you save to a text file or an XML file, load XML files, and clear content. You can separate exceptions or SQL traces from classic traces, then save it at any time.
Each window can automatically save traces in an XML file at real time. To set the file name, you can use the WinTrace.SetLogFile function, or do it directly in the viewer. You can create a daily file (the date is appended to the file name), or disable the log file.
The original framework allows you to send two columns of information (including thread name, icon, and date). It's now possible to send as many columns as you want, but with a small restriction: multi-column is not supported in the main trace window, since many applications (and in different languages) cannot share the main window in "classic" mode and in "multi-column" mode. You must then create a window trace and set the column titles (with just a few lines). In that mode, of course, you lose the automatic thread name and date. You must send them yourself if you need to. Sending many columns of text is performed with the same API as for simple trace. Just add a tabulation ("\t" or char 9) between the different columns.
Here is a C# example:
WinTrace MultiColTrace ;
public void initTrace()
{
// create the window
MultiColTrace = new WinTrace ("MCOL",
"MultiCol trace window") ;
// set the window to multi column mode.
// That automatically remove all columns
MultiColTrace.SetMultiColumn () ;
// must be called before calling setColumnsTitle
// add columns title
MultiColTrace.SetColumnsTitle("col1 \t col2 \t col3");
// columns titles must separated by tabulations
// change the active window (optional)
MultiColTrace.DisplayWin() ;
}Once initialized, use this new WinTrace instance to send data:
// columns data must be separated by tabulations
MultiColTrace.Debug.send("1 \t 2 \t 3") ;
SendObject displays the object class information with the property values. SendType displays class information with static property values:
TTrace.Debug.SendType ("this type", this.GetType() );
TTrace.Debug.SendObject ("this object", this );If SendObject displays the complete structure of the object, with a lot of details, SendValue displays the object value (with multi-dimensional arrays and collections) on many levels. Primitives, and some classes like Date, are displayed as strings:
object obj;
obj = null;
TTrace.Debug.SendValue ("null Object", obj);
obj = new Object();
TTrace.Debug.SendValue ("Object instance", obj);
obj = 123;
TTrace.Debug.SendValue ("integer Object", obj);
obj = "str";
TTrace.Debug.SendValue ("string", obj);
// simple array of Integer
int[] VtArr = new int[10]{7,1,5,2,0,3,4,8,6,9};
TTrace.Debug.SendValue ("simple array", VtArr);
As you can see in the previous example, SendValue is not limited to a simple type. Object properties can point to another object. Recursive object display is limited, by default, to three levels. Object reference is displayed (class@code) on the second column. Objects already displayed are replaced by a "see @" reference. Presently, the Delphi SendValue is limited to variant values (no properties) and arrays.
Here is another screenshot for a complex multidimensional array with user defined bounds and types:
SenDump displays the buffer dump. Sample code:
TTrace.Debug.SendDump ("Dump test", "Unicode", System.Text.Encoding.Unicode.GetBytes(str) ,50) ;
Sendstack and SendCaller let you display the stack information:
TTrace.Debug.SendStack ("Stack test" , 0) ;
TTrace.Debug.SendCaller ("Caller test" , 0) ;
TTrace.Debug.SendBitmap("Bitmap", pictureBox1.Image);
nodeEx.AddXML("<data> Hello XML </data>");
SendTable and AddTable send a multicolumn table in the info panel:
// create the table
TraceTable table = new TraceTable();
// add titles. Individual or multiple columns titles
// can be added, separated by tabs
table.AddColumnTitle("colA"); // first column title
table.AddColumnTitle("colB"); // second column title
table.AddColumnTitle("title column C\tcolD"); // other columns title
// add first line. Individual or multiple columns data
// can be added columns, separated by tabs
table.AddRow();
// add first col
table.AddRowData("a");
// then add other columns (tab separated)
table.AddRowData("b" + "\t" + "c" + "\t" + "d" + "\t" + "e");
// add second line
table.AddRow();
// add all columns data in a single step (tab separated)
table.AddRowData("aa" + "\t" + "data second column" +
"\t" + "cc" + "\t" + "dd" + "\t" + "ee");
// finally send the table
TTrace.Debug.SendTable("Mytable", table);You can send collections (Array, IEnumerable, IDictionary, ICollection) using the same syntax. This can be useful to display LINQ results.
Tracetool will get the first object in the collection to get the titles. It's important that all items should then be of the same kind.
// array of FileInfo[]
string strTempPath = System.IO.Path.GetTempPath();
DirectoryInfo TempPath = new DirectoryInfo(strTempPath);
TTrace.Debug.SendTable("Files in temp path", TempPath.GetFiles());
// Linq to object of FileInfo[]
var LinqToObjectQuery =
from file in TempPath.GetFiles()
where file.Length > 100
orderby file.Length descending
select new
{
file.Name,
file.Length,
file.LastWriteTime,
file
};
TTrace.Debug.SendTable("Files having length>100 in temp path (Linq)",
LinqToObjectQuery);
If you want to follow the values of a variable, you can send it using the classic TTrace.Debug.Send method, but that can produce a lot of traces. In its place, you can use the TTrace.Watches.Send method that shows only the last value. Watches are displayed on a separate window. You can create different watch windows.
In place of overloading the Send method with different parameters, you can use the TraceNodeEx class (that inherits from TraceNode). The advantage is that you can have, for example, many dumps for the same trace, on the "Info" pane. The SendObject, SendType, SendValue, SendDump, SendStack, and the SendCaller functions have the Addxxx counterparts.
You must specify the parent node trace in the constructor parameter. The parent IconIndex, Enabled, and Id properties are used for the newly created trace (a null parent is also accepted).
You can specify the text of the columns separately, specify the icon to use, add object and type, or add Dump to the associated 'Detail' tree. When the node is completed, just call its Send method:
// Create an unicode string with special
// char in front and at the end.
string str = '\u2250' + "azertyuiop qsdfghjklm" + '\u9999' ;
// Create a trace node with the same icon and
// Enabled properties as TTrace.Debug
TraceNodeEx node = new TraceNodeEx (TTrace.Debug) ;
// Fill it
node.LeftMsg = "hello" ;
node.RightMsg = "world" ;
node.IconIndex = 8 ;
node.AddDump (
System.Text.Encoding.Unicode.GetBytes(str) ,50) ;
node.AddDump (
System.Text.Encoding.ASCII.GetBytes(str) ,50) ;
node.AddObject (str) ;
// and finally send it
node.Send () ;The TracenodeEx.Resend function lets you resend the two texts (not members) at any time.
The info panel displays additional information for a specific trace. When available, a small blue circle is visible on the gutter. This can be the object view, dump, stack, or any data that can be displayed in a maximum of three columns. The "Info" button on the toolbar shows or hides this panel.
The classic Microsoft Trace can be redirected to the viewer using the TTraceListener bridge. Here is a sample:
Trace.Listeners.Clear() ;
Trace.Listeners.Add (new TTraceListener ()) ;
int[] myArray = new int[3] { 3, 5 , 5};
Trace.WriteLine ("TraceListener demo") ;
Trace.Write ("myArray : ") ;
Trace.WriteLine (myArray) ;
Microsoft Enterprise Framework (EIF) traces can be redirected to the viewer using the TraceToolEventSink library.
Sample EIF demo:
private static EventSource myEventSource =
new EventSource("EIFDemo");
[STAThread]
static void Main(string[] args) {
// sample 1 : use static ErrorMessageEvent
// msg, severity, error code
ErrorMessageEvent.Raise("Error Message Event", 1, "CODE");
// sample 2 : create a Trace Message Event instance,
// fill it then raise from the event source
TraceMessageEvent messageEvent1 = new TraceMessageEvent();
messageEvent1.Message = "Costly Message";
myEventSource.Raise(messageEvent1 );
// sample 3 : static one line (which wraps the
// above code sequence)
TraceMessageEvent.Raise(myEventSource,
"Static One Line Message");
// sample 4 : static one line which is raised through
// the EventSource.Application EventSource.
TraceMessageEvent.Raise("Static One Line Message " +
"through the Application event source");
}EIF uses a specific configuration file to link traces to the target library (event log, SQL, ...). See the demo configuration file for more details on TraceToolEventSink. Note that this library must be signed (not the case of Log4Net support).
Log4Net traces can be redirected to the viewer using the TraceTool4Log4Net library (TraceTool for Log4Net). Column formatting is done by Log4Net, but tabulations must be used as column separators. Column title must be specified in the CONFIG file.
Sample Log4Net demo:
// Create a logger for use in this class
// (Log4NetDemo.Form1)
private static ILog log = LogManager.GetLogger(
MethodBase.GetCurrentMethod().DeclaringType);
private void butLog_Click(object sender, EventArgs e)
{
// simple test
log.Info("Hello world");
// use an object as message (the object is
// displayed in the info panel)
log.Debug(log);
// exception test (the exception is displayed
// in the info panel)
Exception MyException = new Exception("my exception") ;
log.Error("Received exception",MyException);
}Like for EIF, the Log4Net engine, the configuration file is used to link traces to the library.
As for Log4NET, Log4J traces can be redirected to the viewer using the TraceTool library. Column formatting is done by Log4J, but tabulations must be used as column separators. Column title must be specified in the CONFIG file.
Sample Log4J demo:
Logger logger ; // Log4J logger
Category cat ; // Log4J category
// Initialize Log4J
PropertyConfigurator.configure("log4J.properties");
logger = Logger.getLogger("hello.world");
cat = Category.getInstance(JavaDemo.class);
// simple logger test. Log4J will prepare the trace
// and call the TraceTool appender.
logger.info("Hello world");
// Logger test with attached exception (displayed in info pane)
Exception e = new Exception("my exception") ;
logger.debug("Received exception",e);
// Category test with object value (displayed in info pane)
cat.debug(this);PropertyConfigurator.configure opens the configuration file to know how to link traces to the library. Unlike the .NET support, the TraceTool Log4JAppender class doesn't need to be implemented in another library (Jar).
Since the original idea of TraceTool came from the Gdebug tool, I also provided a DbugIntf.pas file with the same functions. That helps those users switching from Gdebug to TraceTool.
Sample Delphi code:
SendDebug ('Hello world') ;
SendDebugEx ('Hello world', mtWarning);You can extend the TraceTool functionality with plug-ins. Plug-ins can be written in .NET, Delphi, or C++. With plug-ins, you can add, for example, a key logger, Registry logger, or a protocol analyzer to TraceTool without having to create a separate application. Plug-ins receive user actions like deleting a node, pushing the clear button, or trying to close a trace window. Plug-ins can add actions on the viewer menu, or labels and buttons on a trace window. A functional clipboard history is included in the main distribution. The plug-ins must be added in the viewer using the View / Options menu.
To display the OutputDebugString window, activate it in the window menu (show OutputDebugString). The OutputDebugString windows can be paused or cleared using the toolbar. You can also copy selected lines to the Clipboard and save the content to an XML file (the same format as the TraceTool export).
To add a new "Tail" tab, select the Windows/Open Tail File... menu, then select the file you want to watch.
Clipboard operations are allowed, but not exported, since traces are already stored in a file. The number of displayed lines is also specified in the Options menu.
To add a new "Event log" tab, select the Windows/Open Event Log... menu, then select the log you want to watch. New events are automatically added.
Clipboard operations and XML export are allowed (the same format as the TraceTool export).
The viewer can append traces into an XML file (single filename or daily filename). You can specify the maximum number of traces stored in a file. New files appended with _n are created if needed. These files can also be created by the client API. The same Wintrace.setLogFile function is used to specify the client and the viewer log file. Due to security reasons, local log file is not implemented in JavaScript and the Silverlight 2 client API.
When used with the TTrace.Options.SendMode parameter set to 'None', you can write traces in XML files without having to run the viewer. SendMode is not implemented in the JavaScript API (forced to HTTP).
