Infer DSL by using ANT [message #1479339]

Hi,

my DSL is designed to generate a custom persistencelayer. For the code generation I'm using the model inferrer approach.

To integrate the generation into the general build workflow I want to provide an Ant-Target with DSL-sourcefile and target directory as parameters. To achieve this I must call the generation process by my own.

I hoped this thread (Using Xtext and Code Generator without Runtime) is related but as I understand it right he is using the normal generator approach.

Anybody knows how I can call the build process for model inferrer (the process which is invoked if I save my dsl file in the editor) from my class?

hi

the model inferrer is part of the normal appoach.
the only thing you have to care of is to setup the classpath correct.

I've tried to follow your instruction from Using Xtext and Code Generator without Runtime:

Hi,

(1) adapt the generatorFragment in the workflow to create a java main

Code: [Select all] [Show/ hide]
fragment = generator.GeneratorFragment auto-inject {
generateJavaMain = true
}

(2) regenerate the language. you find now a java main generated for the generator (you may use this one or adapt it for your needs)
(3) run the main once in eclipse
(4) use the export -> java -> runnable jar file wizard to create a all in one jar

But after step 2 there is no main generated. I've tried it with a dummy DSL (the domainmodel example) without model inferrer and without xbase and a main was generated.

yes - i thought that would be clear - or at least not matter - you have to create the main yourself.
you may have a look at xbase / xtend tests to see how to initialize the resourceset etc.
feel free to file an enhancement request on that

Can you please tell me where I can find the xbase / xtend tests you mentioned?

they should be somewhere in xtexts source code at git.eclipse.org.
doesnt the domain model example contain such tests?
afaik Lorenzo Bettinis Xtext Book covers that as well
