CodeSnip Old Code (SVN)

Modified re changes made in USettings unit in previous revision.

Changed units which have no specific namespace from MPL v1.1 to MPL v2.0.

Changed name of config file key for determining if $WARNING directives are enabled from "SwitchOffWarnings" to "EmitWarnDirs".

XMLDoc commented units.

Added TWarnings.Defaults class method that creates a TWarnings object containing a list of default warnings.

Removed TWarning constructor that took only a symbol name as parameter and modified code that called it (in only a single place in same unit) to use full form of constructor, passing dummy min. compiler and state values.

* Modified to permit a warning to be switched on as well as off, with state being set by new TWarning.State parameter.
* Made changes to TWarningsPersist and TWarnings.Render to support new warning state.
* Changed IWarnings.Delete method, and implementation, to take a TWarning parameter instead of symbol name string parameter.

Renamed TWarnings.SwitchOff property as Enabled.
Modified all using code.
Also changed name of check box that updates this property in TCodeGenPrefsFrame to suit.

NOTE: Name of item relating to TWarnings.Enabled in User.config remains "SwitchOffWarnings" for backward compatibility reasons.

Reintegrated v4-dev branch into trunk.
Trunk now contains v4 development tree

Simplified enumerator code. Replaced custom enumerator with calls to the TList<T> enumerator. Removed redundant code.
