#4 Uses file not found should fire event

[Mark Ericksen]

The new support for uses should be slightly extended.

Currently, if in a script I have "uses somescript;"
then it errors with not finding the script. This is
correct.

Here is the code that causes it...

procedure Tdws2Compiler.ReadUses;
[...]
if z < 0 then
FMsgs.AddCompilerStop(FTok.HotPos,
Format(CPE_UnknownUnit,[Names[x]]));
[...]
end;

I propose that it be extended to fire the OnInclude (or
an OnUses) event if it is not found. If the script is
not returned or event not assigned *then* the error
message should be raised.

I would like for my program to dynamically load
additional scripts as needed through the uses construct.

A complete recompile must be done with the added unit
(rebuild of the unit-trees). And if we introcude OnInclude
we should introduce OnUnknownSymbol too.

But I think a better way is to have a more detailed
(accessible) error description when compilation failes. I
saw some code, that provides information about missing field
declarations.

The exceptions that get raised for missing field information
is used for ClassCompletion. It has two error types, one for
missing fields or Get/Set methods and one for missing
implementations of the Get/Set methods.

See the new demo under Demos\IDEDemos\ClassCompletion for
how it works.

What would OnUnknownSymbol do? Would that fire when a class
called "TFubar" was referenced but the symbol was
undeclared? Is that the thinking?

I was thinking (at least short-term) that it needs to behave
more like includes. I want to use a script file in multiple
scripts where includes break it because the types are
redeclared.
