There's no syntax highlighting and no code completion for the xtext grammars that I create, not even for the default out-of-the-box example grammar (Greeting Hello).

This problem occurs in the Helios distribution
eclipse-SDK-3.6-xtext-1.0.0-win32.zip
which I downloaded 19 August 2010 from
http://xtext.itemis.com/xtext-language-development-framework /language=en/23947/downloads

Did you try one of the examples, or the simple stub generated by the
wizard? Did you agree with downloading the addition antlr generator?

Hi,

where did you unzip your Eclipse distro. Please make sure that the
filenames don't get to long. Windows will not warn you if unzipping is
unsuccessful.

Just an idea,
Sebastian

I unzipped it to f:\eclipse, thus that's not the cause of the problem.

On my windows installation I resolved the problem by adding the Xtext nature to the project.

However, on my Linux installation (
eclipse-SDK-3.6-xtext-1.0.0-linux-gk.tar.gz
installed in /home/hj/eclipse)
the problem persists, even if I add the Xtext nature to the project.

What can/should I do to (agree with) download(ing) the addition antlr generator, which Sven mentioned?

In
http://wiki.eclipse.org/Xtext/GettingStarted
there's no hint how to (agree with) download(ing) the addition antlr generator and how to configure it.

Where can I find that specific information?

Hi,

if it works using windows and doesn't using linux - have you checked if Crtl+Space is highjacked by another application? Does Content Assist work in Java Files? I Know of some people that face this Problem on Linix in general with eclipse - not specific to Xtext.

Regards
Christian

Hi Hendrik,

you will be asked to download the antlr stuff when you first run the
language generator. Do you have the PDE installed?

Sebastian

When through Help : Install New Software... I try to install from
http://download.itemis.com/updates/milestones
xtext-antlr 1.0.0RC4 S201006081336
Xtext Antlr Runtime Feature 1.0.0.v201006081336
Xtext Antlr SDK Feature 1.0.0.v201006081336
Xtext Antlr Source Feature 1.0.0.v201006081336
Eclipse gives the message
Cannot complete the request. See the error log for details.
"Xtext Antlr Runtime Feature" will be ignored because a newer version is already installed.
"Xtext Antlr SDK Feature" will be ignored because a newer version is already installed.
"Xtext Antlr Source Feature" will be ignored because a newer version is already installed.

And in the installation details I see:
Xtext Antlr SDK Feature 1.0.0.v201006151527 de.itemis.xtext.antlr.sdk.feature.group
Xtext Antlr Runtime Feature 1.0.0.v201006151527 de.itemis.xtext.antlr.feature.feature.group
Xtext Antlr Source Feature 1.0.0.v201006151527 de.itemis.xtext.antlr.feature.source.feature.group

Thus apparently it is not the missing antlr that causes the problem. Or should I use another update site?

Further, code completion and syntax highlighting work fine in the Eclipse Java editors on my Linux installation.
What else could be wrong...?

Hi,

I have the same problem. I have installed eclipse-SDK-3.6-xtext-1.0.0-win32 and did the Getting Started Guide ( http://www.eclipse.org/Xtext/documentation/latest/xtext.html #getting-started) to the point "Run the Generated IDE Plug-in", where it says:

"Try it a bit and discover the default functionality for code completion ( CTRL SPACE even for cross-references), syntax highlighting, syntactic validation, linking errors, outline, find references etc."

Well, all of that doesn't work. Sad

Sad

I followed the Getting Started guide word by word. What am I doing wrong?

I checked my Eclipse installation whether or not it has the Antlr feature and it says: Xtext Antlr SDK Feature 1.0.0.v201006151527.

Here's my complete Eclipse configuration:
http://dl.dropbox.com/u/5602365/eclipe-configuration.txt

Please help!

Regards,

Robin

When running the following scenario (on Mac OS X snow leopard) it works fine:

1. from http://xtext.itemis.com/xtext/language=en/23947/downloads download eclipse-SDK-3.6-xtext-1.0.0-macosx-cocoa.tar.gz
2. unpack it into dir applications
3. run eclipse, following instructions on http://wiki.eclipse.org/Xtext/GettingStarted:
default workspace /Users/hj/Documents/workspace
new : other... : text project, keep defaults
run GenerateMyDsl.mwe2, which gives the following output on the console in file gendsl log
export as deployable plugins
restart eclipse
open file Example.mydsl.
It asks ' Do you want the Xtext nature to be added to this project?', click Yes
Code completion and syntax highlighting work fine.

Hi,

why - yes! I think I played around first with some example at first before I did the tutorial.

I have another project called
org.xtext.example.mydsl.MyDsl
org.xtext.example.mydsl.MyDsl.generator
org.xtext.example.mydsl.MyDsl.ui
in my workspace. I cannot remember how I created this actually. :/

Hmm, should a fresh workspace fix the problem then??

Regards,

Robin
