[gobo-eiffel-develop] Poor error message

[Colin P. A. <co...@co...>]

Gec is giving some poor error messages.

Im am still seing some plain "Syntax error" messages - these could be
greatly improved.

Then I get this:


[VMRC-2] class XM_XSLT_STYLE_ELEMENT (50,2): replicated features
XM_XSLT_STYLE_ELEMENT have not been selected.

I have no clue as to which the replicated features might be. My only
remedy is to try compiling with ISE instead.

Make sure to use 6.3 as 6.2 suffer from a very similar problem for this kind of
error.

Hopefully you see the contextual indication of where the
syntax error is, don't you?

It has been two years now since I had plan to write a better parser.
But it's a big task and I never found time yet to start such 
development. I hope I can do that soon.

In fact the information was in the compiler. There was just a typo
in the code that displays the error message. Instead of displaying
the feature names, it was displaying the name of the current class.
This has now been fixed in the version of the compiler in Subversion,
and now you should get:

[VMRC-2] class XM_XSLT_STYLE_ELEMENT (50,2): replicated features 
XM_XPATH_DEBUGGING_ROUTINES.string_equality_tester, 
XM_XPATH_TREE_ELEMENT.uc_string_equality_tester have not been selected.
----
[VMRC-2] class XM_XSLT_INSTRUCTION (37,2): replicated features 
XM_XPATH_DEBUGGING_ROUTINES.string_equality_tester, 
XM_XPATH_COMPUTED_EXPRESSION.uc_string_equality_tester have not been 
selected.

You should probably rename them so that they share the same name
and hence avoid the need for a 'select' clause.

Sometimes the real error can be a long way back. I can easily lose an
hour a day (I did yesterday) looking for such problems.

Good.

Thanks. That's much better.
