VS2010 Shell Editor shows an exception when loading .PAS modules

goceire · December 7, 2011, 7:35pm

When loading Prism modules (.PAS) in XE2 I receive an exception in VS-2010 Shell (shipped with Prism XE2). This causes the syntax highlighting and code completion to be very temperemental!

Installation is a default installation on Windows 7 Ultimate x64
Installation was performed using "Run as Administator"
Have installed the latest (Update 3) Prism updates, again using “Run as Administrator”

This is from the ActivityLog.XML file generated by VS2010

System.Exception: Could not locate parser! at RemObjects.Oxygene.VisualStudio.Editor.OxygeneClassifier1.get_Parser() at RemObjects.Oxygene.VisualStudio.Editor.OxygeneClassifier1.GetClassificationSpans(SnapshotSpan span) at Microsoft.VisualStudio.Text.Classification.Implementation.ClassifierTagger.d__0.MoveNext() at Microsoft.VisualStudio.Text.Tagging.Implementation.TagAggregator`1.d__16.MoveNext()

Does anyone know how to fix this … looks like an installation problem.

Hello,

Could not locate parser! at
Does anyone know how to fix this

Currently we are not supporting code completion for files that are opened without project. Syntat highlighting could also miss some types etc.
Please try to load solution and open file within that solution. In that case you’ll get correct code completion and syntax highlighting.

Please let us know if you have any other problems with Prism XE2 or if you have such errors for files with loaded solution.

Best regards.

"Please try to load solution and open file within that solution … "
But I am opening the file within a solution

We’re having trouble reproducing this. Just to be clear - you’re loading a file that’s in a project in the current solution, and seeing this error?

Also, are you still on XE2 RTM? or have you upgraded to a more recent release?

As Viktoria noted earlier, there are problems when using 'File | Open file" and picking a file that’s not in a currently loaded project. We’ll be addressing this in an upcoming release.

To be clear :- Yes, I am loading a file as part of a project in the current solution.

I have upgraded to the latest Release (November 2011) - installed using default options, and “Run as Administrator”.

I have exactly the same problem…

viktoriad · December 29, 2011, 5:40pm

We cannot reproduce that problem here. Could you please provide us more details about your Prism XE2 installation? What version do you use, did you try to install latest updates for Prism?
Also do you notice the problem apeears with any prism project (newly created class library for example etc.) or only one project?

dnw · December 29, 2011, 11:14pm

Doesn’t seem to happen with a blank project. If I save my project with a non .pas file active and then open it, it doesn’t error until I click on a .pas file.

Thank you for the info. So the problem appears only for the one project.
What type of project is it? Did you created it with Prism XE2 or previous Prism releases?

It will be very helpful if you could provide us with testcase.

dnw · December 30, 2011, 12:22pm

This is an ASP.NET website project (File…New…ASP.NET). It was created with a previous version of Prism. However, I just created a new project and copied across just my .pas files and the same problem occurs.

I then removed all my code, and the same problem still happens!

Therefore open the attached project. I’m running Windows 7 64bit on an HP machine.

If you don’t get an error straight away try clicking on Librios.Web.API.pas (under App_Code) in the Solution Explorer.

brianl · January 2, 2012, 6:53pm

Thank you for the testcase. I think we’ve finally nailed this one down. The fix will be in an upcoming beta release.

goceire · February 1, 2012, 9:44am

Looks like this has been fixed in the January 2012 release (Update 4). Nice work folks!

mh · February 4, 2012, 1:55pm

thanx for the confirmation — glad it’s all working for you now.
