delphi - dwscript - 任何人都可以帮助编辑调试器示例吗？

Question

我正在查看 Delphi 的出色 dwscript，请参见此处，它提供了一组有用的类来为您的应用程序实现内置的 pascal 脚本。对于如何将提供的调试接口与编辑器链接在一起的示例，我将非常感谢一些帮助，以便我可以创建断点（理想情况下可以查看手表）。请问有人走过这条路吗？谢谢，布赖恩

Most of the debugger doc is currently in this post

Also the debugger interface hasn't changed much (if at all) since the original DWScript II (on SourceForge), so the old demos there should hopefully still work with minimal adjustments.

For breakpoints, you basically just check the source position of the Expr you get in DoDebug/OnDebug against the list of breakpoints. One simple and efficient way is to merely use TBits -using it as a boolean array of which lines have a breakpoint). Evaluating/watching requires looking up a symbol, which will give you it's stack address, you can then lookup the value in the stack.

I'll try to add/update a debugging tasks demo for v2.2 (unless someone else does it before me ;) )

edit: as of 11-02-14 there is a TdwsDebugger component to facilitate debugging tasks.
