Using xtext without eclipse [message #831084]

What i want to do is using xtext with eclipse first, define a grammar and then let xtext create a parser. Than i want to invoke the parser from another program using java. Actually i just need to know if my defined rules conform to the defined grammar.

Thanks in advance.

What do you mean with "my defined rules"?

Normally I would suggest to use the org.eclipse.xtext.xtend2.standalone jar to include it into your java project, start up your guice module, query the injection provider for the parser and parse it.

ParserRule parseRule = grammerAccess.getMyParseRule();
IParser parser = injector.getInstance( IParser.class );
IParseResult result = parser.parse( parseRule , new StringReader( stringToParse) )

If you want to parse a whole file, use the IResourceValidator.

Kind regards
Michael

Well you can call them as you wish in the end its just a line of text which should conform to the defined grammar. I just called them rules because they are mathematical rules.

Ok thanks for the info, i will try it.

Hi,

another possibility is to use std means as described here http://www.eclipse.org/forums/index.php/mv/msg/200108/638596/#msg_638596
