Compiler source now also publicly available

Details

Created: October 16 2019

With the complete disappearance of our former competitor in the Xbase for .Net area (did you look at their website recently ?) we have decided that it is now time to make the source code to our compiler publicy available. After all we have nothing to hide, in fact we are very proud of what we have achieved in the last four years!

You will find the source code to the compiler (and Help and Manual documentation) on https://github.com/X-Sharp/XSharpDev.
This source code is shared under the Apache 2.0 license. Some source files still speak of the "X# compiler source code License". That will be changed in the coming weeks.

We have a small private repository still where the installer is located along with the certificates and keys. But that does not have anything you would need to rebuild the compiler.

XSharp Bandol 2.08 GA released

Details

Created: October 16 2019

We have just released a new installer for XSharp Bandol 2.08

This build fixes a few issues found in Bandol 2.07. It also adds support for Visual Foxpro class syntax and adds support for several Visual FoxPro commands. And it adds support for workarea events/
See the what's new document for the detailed list of changes.
We have also made some more steps towards FoxPro compatibility. In the FoxPro dialect you can now have statements without FUNCTION/PROCEDURE heading at the start of your program and we have also enabled AND, OR, XOR and NOT as keywords (as alternatives for .AND., .OR. etc.). FoxPro class creation is expected for the next build.

A public installer for this build is expected later this week.

Performance Tips - 1

Details

Created: September 27 2019

With this article I want to start a series of articles with tips that can help improve the performance of your apps when they are moved from Visual Objects and/or Vulcan to X#.

The first tip is to use the IS comparison in stead of IsInstanceOf()

Try the following code in a VO Console application:

FUNCTION start AS VOID 
 LOCAL oErr AS OBJECT
 LOCAL nI AS LONG
 LOCAL f AS FLOAT
 oErr := Error{} 
 f := Seconds()
 nI := 0
 FOR VAR nX := 1 TO 10_000_000
    IF IsInstanceOf(oErr, #Error)
       nI++
    ENDIF
 NEXT 
 ? Seconds() - f, nI
 f := Seconds()
 FOR VAR nX := 1 TO 10_000_000
    IF oErr IS Error
       nI++
    ENDIF
 NEXT 
 ? Seconds() - f, nI
 WAIT

IL-Spy 4 & 5 Plugin

Details

Created: September 24 2019

New version(s) of the XSharp Plugin for IL-Spy are available : One for IL-Spy 4, and the other one for IL-Spy 5.

If you don't know, ILSpy is the open-source .NET assembly browser and decompiler, and you can use ILSpy to view and decompile .NET assembly as XSharp Language.

To do so, first get the ILSpy binaries and unzip them in a folder.

Then get the ILSpy Plugin in the Downloads/General/Tools section, and unzip the DLL in the same folder as the ILSpy Binaries.

Now, when running ISpy, you can set the language as XSharp.

The full source code of the Plugin is available in the public XSharp Repository on Github; you can also view there the current state of developement of the tool ( What is working currently, Changelog, ... )
