Hi,
I have a plugin (XText/XTend)I use to edit my DSL and generate some code form it each time one DSL file is saved.
So far, so good.

Now that it seems OK I would like to have also a command-line utility to "compile" a [set of] DSL files.
No editing capability.
No graphics.
Possibly small.

Is something like that possible, somehow (without rewriting everything)?

TiA
Mauro

Hi

a) doesn't the builder do it automatically interactively?

b) run your XXXStandaloneSetup.doSetUp(), create an XXXResource from
your text and that will at least do the compile

c) if you want small, the ANTLr is huge

The Xtext model is EBNF with model-annotations that appears to be rather
easy to translate into LALR, so I'm currently developing QVTo and
Acceleo transformations from Xtext to LPG; initially just to get a solid
check that my grammar is not exploiting backtracking, but eventually to
get a 10-fold saving in code size and a 2-fold improvement in speed.

Of course, but what I'm looking for is a kind of command-line tool which
should accept a list of DSL files as arguments and produce the generated
files in a suitable dir (either "$(pwd)/src-gen" or "-o whatever"),
possibly taking care of creation of a "Xtext project", if needed.

Can You elaborate, please?
Should I write a "static main()" to create an SIDLResource and then call
SIDELStandaloneSetup.doSetUp()?
Is that all?

I know, but it's much smaller than a complete eclipse installation,
especially if you consider I would need EMF, Xtext, Xtend, ...

I'm looking for something easyly derivable from my current code (which
is working well).

The other way around. SIDELStandaloneSetup.doSetUp() ensures that Xtext
support is registered for *.sidel files, so that a ResourceSet will
automatically create an Xtext Resource from a text stream.

You won't easily get rid of EMF (or Xtend). Xtext might be optional for
compile-only.

My aim is to exploit Xtext for editors and re-use the grammar for a more
compact LPG-based parser. You would just add an 'LpgParserFragment' to
your MWE workflow so that your Xtext grammar is converted to an LPG
parser. Don't wait for it.

There no such command line tool, but it's generally possible to build one.
For that you need to
1) create an injector using the StandaloneSetup (as Ed suggested),
2) obtain a ResourceSet from the created injector,
3) obtain an instance of IGenerator
4) -"- and instance of IFileSystemAccess
5) load the models you want to generate code for into the resourceset
6) invoke the generator using the resources and the file system access

I might have forgotten something. Just ask if you got stuck.
Also if you are able to generalize this a bit we are happy to accept
contributions :-)
