[Reuseware-users] Version 0.8 of the Reuseware Composition Framework released

[Jendrik J. <Jen...@tu...>]

Version 0.8 of the Reuseware Composition Framework has been released and
is now available for download.

With this release, the Reuseware Composition Framework fully supports
metamodel-based languages. New concepts and new tooling make it even
easier to define composition systems for arbitrary languages. The core
of the framework has been rewritten for this version: Reuseware-based
composition systems now integrate smoothly with many Eclipse- and
EMF-based tools.

[Reuseware-users] bind full constructs

[Andreas L. <and...@st...>]

Hi all,

is is me again and after I succeeded in most of the things I wanted to
do, I have one more question:
I would like to use something like "bind x with z", as you did in one
of your Examples (Modular Xcerpt: "bind ct with ctWrapper")
But this alwas produeces a Java Null Pointer Exceptioin when the
workspace is built. How can I use this kind of binding anyway?

(Unfortunately I can not try the Modular Xcerpt example myself, as the
Text Parsers won't be built)

Thanks in advance, Andreas

Re: [Reuseware-users] How to reuse composers in composers

[Andreas L. <and...@st...>]

Hi,

please forget about the second question in my last mail. Now I can do 
more than 30 checks as well. It must have been something else causing 
the error.
Sorry for that,

Andreas

Re: [Reuseware-users] How to reuse composers in composers

[Andreas L. <and...@gm...>]

Hi all,

with your answer, Jendrik, I now can call my own composers, thank you 
very much. But initially I was searching for another way to do it: Is it 
possible to match a pattern and then (instead of calling bind or extend 
there) to call my own composer there?

And in case this is not possible, here is my second question:
Now I am calling my composer and then - as in your Java-weaving - 
iterate over the constructs of the input and test via "if ..." whether 
the current construct matches my pattern. Unfortunately my pattern is 
quite complex and I need many checks there. I experience, that the 
number of checks via "if (..." seems is somehow limited to 30. Is there 
a way of performing more than these 30 checks?

Thank you very much,

Andreas

Re: [Reuseware-users] How to reuse composers in composers

[Jendrik J. <jen...@tu...>]

Hi,

momentarily it is only possible to call composers by defining a language 
construct (i.e., a non-terminal in the grammar) for that purpose.

If you want to call a composer inside a composer definition, you need to 
extende the composition language itself by introducing a new construct 
as composer

minimalcl.Composer = MyComposer;
MyComposer         = arg1:NT1, arg2:NT2, ... ;

For the concrete syntax it is the best to copy the one for the basic 
composition language (from bc.cs in "org.reuseware.fracola/models" in 
SVN) and add concrete syntax for your new composers. You can also remove 
concrete syntax for constructs you do not want to support in your 
"customized" composition language.

cheers,
Jendrik

[Reuseware-users] wrong decisions

[Andreas L. <and...@st...>]

Hi all,

my second problem with grammars in reuseware is the following.
I would like reuseware to be able to parse
#include <foo.h>
and my plan was to do it like this:
abstract:
PrPrIncludeGlobal              = name:GlobalIncludeName;
GlobalIncludeName              = value:S;
concrete:
PrPrIncludeGlobal             ::= "#" "include" name;
GlobalIncludeName             ::= value['<' (~('>'|'\\') | '\\' . )* '>'];

This works fine with the local include (#include "foo.h"), but it fails 
for the global variant, as with these grammars produce an error during 
the parsing of code, whenever there occurs a "<" that is not part of an 
#include.

What is the problem?

Regards,

Andreas

[Reuseware-users] problem with reproducibility

[Andreas L. <and...@st...>]

Hi all,

one major problem with reuseware I experience is, that identical 
grammars don't necessarily lead to identical results. This problem 
occurs in two variations:

1. If generating a text parser from a concrete grammar results in an 
error, it often helps to delete the created folder and just try again.
2. More severe: If the text parser(s) is (are) generated, but reuseware 
can't parse some code, this is not necesarily due to wrong grammars. 
Often redoing all the steps (map to ecore, generate language plugin, 
generate text parser) without changing the grammars at all helps.

As an example I attach grammars for a subset (!!!) of C. With these 
grammars reuseware understands this program (this is not meant to be a 
good parallelization....):
#include <time.h>
#include <stdlib.h>
#include <stdio.h>

#define LENGTH 1000000
#define MAX_NUM 99

void quicksort(int field[], int left, int right) {


    int index_l, index_r, tmp;
    index_l=left-1;
    index_r=right;

    for(;;){
      while(field[++index_l]< field[right]);
      while((index_r > index_l) && field[--index_r]>field[right]);
      if(index_l>=index_r) break;

      tmp=field[index_l]; field[index_l]=field[index_r]; field[index_r]=tmp;
    }

    tmp=field[index_l]; field[index_l]=field[right]; field[right]=tmp;

    #pragma omp parallel sections
    {

      #pragma omp section
      quicksort(field, left, index_l-1);

      #pragma omp section
      quicksort(field, index_l+1, right);

    }

  }

}

int main(int argc, char *args[]) {

  int to_sort[LENGTH];
  int index;

  srand(time(NULL));

  printf("Filling field...");
  for (index = 0; index <= LENGTH-1; index++) {
    to_sort[index] = rand()%(MAX_NUM - 1) + 1;
  }
  printf("done.\n");

  printf("Sorting...");
  quicksort(to_sort, 0, LENGTH-1);
  printf("done.\n");

  return 0;

}

But I usually have to do all the steps at least two times, until 
reuseware accepts the code.

What can be the problem?

Andreas Leha

Re: [Reuseware-users] problems with reuseware accepting code

[Jendrik J. <jen...@tu...>]

Hi Andreas,

please apologize for the late reply.

At first, the "*dummy();" thing works,
because according to the grammar "*dummy();" is already a complete
program and resueware parses only this part. If it finds one complete 
programs it attempts to parse the remaining part as well, but gives no 
error if it fails (this might actually be a bug).
	
This means the example can not be parsed regardlessly if you put 
"*dummy{};" in front of it or not. Consequently there must be mistakes 
in the grammar. The grammar is quiet big, so it is hard for me to get an 
overview.

One problem seems to be the return type of a method:

* main( int argc, char *args[] ) {

}

is parsed, while

int main( int argc, char *args[] ) {

}

is not.

Another problem is there with array declarations:

     int array;

is okay, but

     int array[100];

gives errors.

The reuseware tooling is not very advanced for grammar debugging. If you 
can not find the mistakes, one thing you could do is looking at the 
generated ANTLR file "c.g" in
"de.tudresden.reuseware.language.c.textsyntax.c"
and analyze it with some ANTLR tool. I think they have a good graphical 
tool now, but I have not tried it myself (www.antlr.org).

Hope that helps,
Jendrik

[Reuseware-users] problems with reuseware accepting code

[Andreas L. <and...@st...>]

Hi there,

I am trying to get reuseware to understand (at least partial) C code. 
Unfortunatly I experience strange behaviour: reuseware accepts this:
  *dummy{};
 
  int main( int argc, char *args[] ) {
    int index;
    int array[100];

    for(index = 0; index < 100; index++) {
      array[index] = 0;
    }

    return 0;
  }
But without the leading dummy line, the code raises errors. Strange is, 
that just regenerating language plugins and text parsers leads to 
different errors here. Anyway, all the errors are similar to this:
state 0 (decision=75) no viable alt; token=[@5,10:12='int',<97>,1:10]
or
mismatched token: [@5,10:12='int',<97>,1:10]; expecting ')'
And they indicate, that function definitions or array declarations... 
are not recognized.

So my question is: Why does reuseware accept C code just after the 
leading line "*dummy{};"?

I've attached the grammars (that follow closely the K&R, 2nd edition).

Re: [Reuseware-users] java- with CoMoGen

[Jendrik J. <jen...@tu...>]

Hi Sascha,

unfortunately, there are still some bugs in the graphical 
CoMoGen-Wizard. Some were fixed recently in the SVN version. If you 
really want to use it, you could get the latest version of the Framework 
from SVN (see Download side). Otherwise I would suggest you do the 
extension manually for now, like in the tutorial. I am confident that we 
will have a new release soon.

Re: [Reuseware-users] java- with CoMoGen

[Sascha D. <s87...@ma...>]

hi again,

i forgot to say, that i'm using Eclipse 3.3.1 with EMF 2.3.1.

and to say something more to my problem:
when i add a slot and store it in the reuse models file 
(reuse.java.ecore is created), than the generation of the plugin from 
this ecore-file lead to some classes, like Reuse.javaFactory.java which 
are not correct source-file names for java-classes.
i think that is a problem for the errors in the plugin.

but maybe i did something wrong?

greets,
Sascha

[Reuseware-users] java- with CoMoGen

[Sascha D. <s87...@in...>]

hi,

i tryed the java--tutorial as it is explained on the website.

now i tryed to do this tutorial with the help of the CoMoGen(?)-subsytem.

first i created the two files java.as and java.cs with the content of the
website. then i added a slot to the MemberDeclaration in java.as.

this results in two files java.ecore and reuse.java.ecore.

when i try to generate a language-plugin from the reuse.java.ecore file,
then the generated plugin contains different errors.
when i map the ecore-file to an abstract-sytax-file (reuse.java.as) and
use this one for generating the plugin, then the plugin-folder is empty.

(i also got errors when i try to generate the text-parser plugin, from a
file reuse.java.cs which i generated with the help of the definition from
the tutorial)

what did i do wrong?
is there somewhere an explanation how to use CoMoGen right?

greetz,
Sascha

If the ".g" file is empty, there must be another error. Do you maybe get

Re: [Reuseware-users] Java- Tutorial. Error while building the text parser

[Andreas L. <and...@st...>]

Hi,

the rjava.g file is an empty file, and the rjava.cs is just copied from 
the tutorial.
But I attach both.

Re: [Reuseware-users] Java- Tutorial. Error while building the text parser

[Jendrik J. <jen...@tu...>]

Hi,

please feel free to answer to the list so others can also profit from 
the discussion. :)

There must be an error in the generated parser file (the "rjava.g") 
which is transformed by the ANTLR tool into Java files. Usually you 
should get an error on the "rjava.cs" file.

Can you sent the rjava.cs and rjava.g file?

Re: [Reuseware-users] Java- Tutorial. Error while building the text parser

[Jendrik J. <jen...@tu...>]

Hi Andreas,

sounds like an Eclipse-related problem.

Try to refresh the project.

Try to clean the project (Project > Clean...). This often helps.

If not, please check:

Do your parser generation complete without errors?
(I.e., are there no errors on the "rjava.cs" file after parser 
generation and is the package 
"de.tudresden.reuseware.language.reusejava.textsyntax.rjava" + Java 
files created inside the "src" folder?)

cheers,
Jendrik

[Reuseware-users] Java- Tutorial. Error while building the text parser

[Andreas L. <and...@st...>]

Trying to do the Java- Tutorial (or any other simial project) I get this 
error when building the text parser:

<<
Project de.tudresden.reuseware.language.reusejava.textsyntax.rjava is 
missing required source folder: 'src'
 >>

But this folder exists.

Any quick solution to this?


Thanks,

Andreas

[Reuseware-users] Frage zum Java--Tutorial

[Sascha D. <s87...@ma...>]

Hallo,

ich hab das Java--Tutorial ausprobiert und bin dabei auf Probleme gestossen.
Ich benutzte Eclipse 3.2.2 mit EMF 2.2.0 und habe mir CoCoNut, CoMoGen 
und FraCoLa in der Version 0.5.1 heruntergeladen.

Danach wollte ich das Tutorial unter 
http://reuseware.sourceforge.net/index.php?title=Java_Tutorial 
nachvollziehen.
Ich komme dabei bis zu der Stelle an der ich den Parser für die Reuse 
Language aus der Datei rjava.cs genrieren soll.
Daraufhin werden mir in dieser Datei Fehler angezeigt wie

mismatched char: '' on line 8; expecting char ']'
oder
1:1: Tokens : ( T9 | T10 | T11 | T12 | T13 | T14 | T15 | T16 | T17 | T18 
| T19 | WS | LB | VALUE | REGEX | IDENTIFIER ); state 0 (decision=10) no 
viable alt line 9:47; char='.'

angezeigt.
Danach funktionieren dann natürlich auch weitere Teile des Tutorials 
nicht mehr.

An was könnte es liegen, dass danach Fehler vom Parser angezeigt werden? 
Liegt es überhaupt daran? Oder ist das normal?


Gruss,
Sascha

[Reuseware-users] type casting in composition programs

[Jakob H. <jak...@tu...>]

Hi,

One of the modular xcerpt composers currently look like this (slightly  =

modified from SVN version to show the point):

define composer modularxcerpt.QualifiedQueryTermComposer(moduleName,  =

queryTerm) {

	// Resolve the fragment name into a location (URI, the module ID)
	fragmentlist componentmodel.Location moduleID =3D ->moduleName;

	// Use store: "out"
    	fragmentlist xcerpt.QueryTerm qtWrapper =3D
    		'store [ modul [ <<moduleID>> ], visibility [ "out" ], <<qTerm>>  =

]'.mxcerpt;
	=

	fragmentlist xcerpt.QuotedString quotedModuleID =3D '"' + moduleID  =

+ '"'.mxcerpt;
	bind moduleID on qtWrapper with quotedModuleID;
	=

	// Bind intentional query term to store wrapper
	bind qTerm on qtWrapper with queryTerm;

	// Return store wrapper
	return qtWrapper;
}

The QuotedString quotedModuleID is constructed with a "hack": untyped  =

string concatenation. I want to bind the slot 'moduleID' with the value =
of  =

the fragment moduleID (of type Location). Instead of Lines 10-11, removi=
ng  =

the "hack", I want to write:

bind moduleID on qtWrapper with (xcerpt.QuotedString)moduleID;

Thus casting the type of moduleID from Location to QuotedString (which i=
s  =

possible, since the value of the fragment can be represented both as a  =

Location and as a quoted string). Notice that the '"' of the quoted  =

strings are (should be) just concrete syntax, so they shouldn't be a  =

problem.

Is this a reasonable solution? Can we implement it? Is this relevant to =
 =

Sven's improvements of the composition language?

Let me know what you think.

Cheers,
Jakob
ps. is this the right forum for these kinds of issues? ds.
