CodeSnip Old Code (SVN)

Fixed bug introduced into TPascalSourceGen when its IncludeSnippet method was modified to accept a TSnippetID parameter instead a TSnippet: this class was failing to generate source code for snippets not in the database. Fixed included changing Include snippet's parameter to ISnippet and then modifying TPascalSourceGen and all the classes it depends upon to work with ISnippet instances instead of TSnippet.
Also modified code that calls TPascalSourceGen.IncludeSnippet re the parameter changes.

Changed ISnippetView to have a SnippetID property of type TSnippetID instead of a Snippet property of type TSnippet.
Modified calling code accordingly.

Modified comments and string literals referring to the "user" database or "user-defined snippets" to remove or qualify the word "user".

Changed TDatabase.SelectSnippets to take a simple function reference as its parameter instead of IDBFilter instance.
Modified calling code accordingly.
Removed now-redundant IDBFilter interface and implementations in TDBFilter and TDelegatedDBFilter.

Renamed IReadOnlySnippet as ISnippet and made required changes to affected code.
Also renamed TDatabase's LookupReadOnlySnippet method and LookupSnippet.

Changed code that accessed _Database.Select to use Database.SelectSnippets instead.
Deleted Select method from IDatabase and _TDatabase.

Removed ability to generate source code of a snippets in a category from TSnippetSourceGen and replaced it with support for generating source code of snippets in a tag.

Renamed IDatabase and Database function, along with internal TDatabase class and PvtDatabase varibale by placing underscore in front of their names. This is to flag the items as "legacy" and to avoid name clashes with new database code being developed.
Modified all code that calls Database to use _Database instead.

Removed assertions that test for nil snippet after calls to Database.Lookup: this method now raises an exception when the lookup fails (see revision 3984).

Changed IQuery.GetCatSelection and implementation to return a ISnippetIDList instead of populating a given TSnippetList.
Modified code in TSnippetSourceGen that uses IQuery.GetCatSelection accordingly.
