CodeSnip Old Code (SVN)

Added an additional out parameter to several methods of TSnippetValidator that pass back information about the selection that could be used to highlight any errors. Modified code accordingly.

Changed ETaggedTextLexer to descend from EValidation and modified code of TTaggedTextLexer to pass information about approximate location of errors to ETaggedTextLexer exceptions.

* Added new EValidation exception class that optionally records a selection specifying location of an error where this makes sense.
* Modified EDataEntry exception to descends from EValidation: new constructors added to take selections.

Added new TSelection record that encapsulates a selection defined by its start position and length.

Removed unused EREMLEntities exception class.

Corrected comment that said validator raises exception when it does not.

Some methods were raising an ECodeSnip derived exception when programming faults were detected. These were replaced by assertions.

Partially implemented suggestion in comment to feature request 3105288 so that errors reported when clicking "Render Extra Information" button on Snippets Editor's Extra Information tab now refocuses memo control containing error.

* Created new UMemoCaretPosDisplayMgr unit to take care of displaying caret position of memo controls in associated labels.
* Revised snippets editor to use new TMemoCaretPosDisplayMgr to display memo caret positions and added caret position display for extra information memo.
