CodeSnip Old Code (SVN)

Overhauled TUserInfo record:
+ Removed Assign method (not needed: direct assignment works just fine)
+ Removed Init method: can use CreateNull method in its place
+ Corrected spelling of "null" in method names.
+ Made Details and Comments fields into read-only properties and so made record immutable.
Updated using code re changes.

Overhauled TUserDetails record:
+ Removed Assign method (not needed: direct assignment works just fine)
+ Removed Init method: can use CreateNull method in its place
+ Corrected spelling of "null" in method names.
+ Made Name and Email properties read only and so made record immutable.
Updated using code re changes.

Removed temporary Category (ID) property from TSnippetBase and all code that supported using the property.
Updated affected code by removing all references to category IDs.

Removed redundant TSnippetInfo method.

Removed reference to TReservedCategories by hard wiring the special import category ID as a string literal.

Note: this is a temporary change en-route to removing support for categories.

Added new IStringList.IsEmpty method and its implementation in TIStringList.
Modified all code that tested IStringList.Count against zero to use IStringList.IsEmpty intead.

Modified TCodeImporter to ensure snippet's title is non-empty: uses snippet ID if no title present for a snippet.

Replaced TSnippet's Language function with LanguageID property that uses the pre-existing implementation in TDBSnippet. Modified using code accordingly.
Deleted TSnippet.HighlightSource property. Modified using code to deduce if source code highlighting required by examining the LanguageID property.

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.

Modified database loader and import code to add a single tag to each snippet. In database loader this is based on snippet's category while importers add a tag describing import source.
