Where: http://sourceforge.net/projects/tclcsharp Description: Tcl/CSharp is an implementation of a Tcl interpreter written entirely in C#. Tcl/CSharp was ported from Jacl (Tcl Java implementation) in version 1.3.1 It offers a bridge to .NET Framework for Tcl code. Updated: 12/2004Contact: Artur TrzewikSee also: Jacl Jacl.NET .NET C#
Some code examples that show where tclcsharp can be valuable:
# example how to use .NET Framework for accessing web package require java java::load -gac System.dll set webclient [java::new System.Net.WebClient] # it can be used also with https set bytearr [$webclient DownloadData http://www.google.de] puts [[java::call System.Text.Encoding get_UTF8] GetString $bytearr] # example how to use .NET Framework for doing XML per DOM package require java java::load -gac System.Xml.dll set doc [java::new System.Xml.XmlDocument] set node [$doc CreateElement tclsharp] $doc AppendChild $node $node AppendChild [$doc CreateTextNode "is usable for many things"] puts [[$doc get_DocumentElement] get_OuterXml] # accessing operation system. here listing all processes package require java java::load -gac System.dll set procs [java::call System.Diagnostics.Process GetProcesses] for {set x 0} {$x<[$procs length]} {incr x} { set proc [$procs get $x] puts [format "%4s %15s %2s %20s" [java::prop $proc Id] \ [java::prop $proc ProcessName] [java::prop $proc BasePriority] \ [java::prop $proc MainWindowTitle]] }
Some performance comparation for 3 Tcl-Interpreters (c, java and c#) maked with tclbench (part of tcllib). Testmachine: Intel Pentium 1.6 GHz 256 MByte RAMTcl - active state distribution 8.4.3 Jacl 1.2.6 with SUN Java 1.4.3 Tclsharp with .NET 1.1

Many expensive algorithms needed for example for xml, crypto, networking can be done by using .NET framework.
