txtuml's Issues

Error: The method +(int) is undefined

When trying to compile the following lines of code in an effect:

int y = 3;
int x = y + 1;

Where numForward is an attribute in the current class. However it is also produced when local variables are used.

Check java reserved names

state final; is a perfect state declaration in XtxtUML, but the generated code is bogus:

public class final extends StateMachine.State {}

Illegal project name is allowed

The wizard to create a new txtUML project allows illegal project names. These result in errors upon the creation of the project.

Description Resource    Path    Location    Type
Bundle symbolic name contains illegal characters.  Legal characters are A-Z a-z 0-9 . _ -   MANIFEST.MF /proba a/META-INF   line 1  Plug-in Problem

Please review the export.uml2.tests and export.uml2.tests.models projects and update them according to the recent changes that were made to the model exportation. These changes affected even the expected output so some tests might have become out-of-date.

The expression `this` cannot be typed in action of state or transition

The following code:

model ErrorReportingModel {
    class A {
        state A1 {
            entry {
                send new S() to this;
            }
        }
    }
    signal S;
}

Gives the error message
Type mismatch: cannot convert the expression to Class

JtxtUML incremental validation is too heavy

When a reconcile happens, the JtxtUML validation rules are checked for the whole file instead of the fragment modified.

Generated files should be removed when .xtxtuml file is deleted

Support for shorthand operators

Operators like prefix and postfix ++, and assignment operators like += should be supported.

txtUML Project should not be a plugin project

If this is used to handle dependencies a classpath container should be defined.

Collection support needed, confusing error message

Collection<PerformanceTestModel.A> a = this->PerformanceTestModel.AB.a;

This instruction produces the following error:

Type mismatch: cannot convert from Collection<PerformanceTestModel.A> to Collection<PerformanceTestModel.A>

Maybe a java type should not be used that way, but then what is the suggested method to deal with collection types?

Create template proposals for structural elements

For more information, see https://eclipse.org/Xtext/documentation/304_ide_concepts.html#templates.

Exceptions while trying to edit code

The edited code (in class A):

        private void createChild() {
            PerformanceTestModel.B b = new PerformanceTestModel.B();
            b.
        }

Tried to autocomplete after b.

Let it possible to omit 1 from association end multiplicity

Currently an association can be declared like this:

    association AB {
        public 1 A a;
        public * B b;
    }

It would be much more nicer to write it implicitely declaring a as single multiplicity:

    association AB {
        public A a;
        public *B b;
    }

Omitting 1 is not only forbidden, but produces an exception:

New txtUML Model wizard should set a default value for source directory

Transition names should be optional

In the declaration of a transition:

transition init_A1 {
    from init;
    to A2;
}

It should be beneficial to be able omit the name, it can be generated from the from and to declarations.
The name should be in readable format, if the transition goes from A to B it should be A_B
If there are multiple transitions from A to B they should be labeled A_B_n where n is a number based on the order of declarations.

Create unified IDE-level logging

This could be used in all IDE-centric plugin, like hu.elte.txtuml.project

Popup did not appear on compilation errors

After a few focus switches between the eclipse and other programs it appeared.

Layout definition for state machines

Currently, it is possible to define the layout of class diagrams. This should be possible also for state machines.

Improve validations and completion for send statements

Disable explicitly sending null and boolean literals. Also disable sending to explicit target null and boolean literals. Values null, true and false should be removed from the code completion in the place of signal and also at the target.

Re-export of unchanged model

Diagram generation re-exports the UML model each time a diagram is generated. Re-export should only be done if the txtUML model has changed. Otherwise only the changed diagrams should be re-generated.
(The long-term goal is incremental transformation.)

Transition effect should receive the signal causing the transition

Otherwise it is not possible to use the signal properties.

Migrate to Mars

The Papyrus API has been changed compared to Luna, therefore the Papyrus diagram generation plugin needs to be adapted.

Possibility to declare multiple states in one line when they have no body

Instead of:

state A1;
state A2;
state A3;
state A4;

it would be nice to write

state A1, A2, A3, A4;

JtxtUML validation is incomplete

Complete the validation of the structural part of the JtxtUML models and then add validation rules for the action code as well.

Split models into more files?

It is inevitable to let JtxtUML models to be split into more files. So the only question that remains is how to do it.

For the validation and the UML2 export it is a necessity to maintain some connection between the files of a model as we need to decide which files are part of it and which are not. My proposal is to keep all the files of a model in a single Java package and its subpackages. It would also be a good idea to have a main class representing the model in the top package. The subpackages could represent packages of the model.

Cannot install without Moka

Use clean Eclipse Luna Java edition, try to install the txtUML update site generated from txtUML trunk as of 2015-10-14.
The install fails, because it cannot find Moka.

Cannot complete the install because one or more required items could not be found.
  Software being installed: txtUML 0.1.1.201510140920 (hu.elte.txtuml.feature.feature.group 0.1.1.201510140920)
  Missing requirement: txtUML Diagnostic Extensions 0.1.0.201510140920 (hu.elte.txtuml.diagnostics 0.1.0.201510140920) requires 'bundle org.eclipse.papyrus.moka.ui 0.0.0' but it could not be found

Changing Action.create?

Action.create might be enhanced with the use of lambda expressions.

Current syntax (with an int and a boolean parameter):

A a = Action.create(A.class, 2, true);

New syntax would be:

A a = Action.create(A::new, 2, true);

Pros:

The creation of the new object would need no reflection and therefore it would be much faster.
The number and type of the constructor parameters could be checked at compile time.

Cons:

This change has to be applied to every level of our implementation.

NullPointerException on model export

The performance test model produces that. There is a validation error in the model, and there are invalid files, but the error is not caused by neither of them.

Texts in the 'new txtUML model' wizard

Text change suggestions:

"Type name is empty" ==> "Model name is empty"
"Type of model" ==> "Model syntax"
"standard txtUML Model (Pure Java syntax)" ==> "JtxtUML (Java syntax)"
"XtxtUML Model (Custom modelling syntax)" ==> "XtxtUML (custom syntax)"

Generated JtxtUML code is not properly formatted

The last step of the code generation should be an automatic formatting.

Object equality and inequality checks

The current support for object equality and inequality checks (the use of == and != operators on objects) in exported models was quickly made to avoid a NullPointerException during exportation. Please, review this and look for a better solution if possible.

C++ code generator is not available on the Eclipse interface

First, the code generator should be updated according to the new activity export, then make it available from the Eclipse interface.

Enhance XtxtUML formatting

Now the formatter emits a single line, and only wraps it when it is longer than 80 characters. Implement a custom formatter.

Action.create fails when the constructor has primitive parameters

The create action fails (returns null) when I give it a parameter of type int.
A a = Action.create(PerformanceTestModel_.A.class, 10000);

The constructor looks like this:

public A(final int numCycles) {
    //...
}

The workaround is to use Integer parameter instead of an int (but that is a validator error).

Also, when the create action fails it should raise an exception and stop the execution instead of silently returning a null that causes a NullPointerException later.

Use :: for qualified names instead of .

The same . operator means different things, so this->PerformanceTestModel.AB.a.selectAny() must be written like (this->PerformanceTestModel.AB.a).selectAny(), that is strange. It would be nice to use double colon instead in qualified names.

ModelExecutorThread.shutdown should block until terminated

I created a patch that solves this issue
ModelExecutorThread.java.txt

External class support in XtxtUML?

Is there support for defining external classes in the custom syntax?

Class name cannot be referenced in action code of state or transition

model PerformanceTestModel {
    class A {
        state S {
            entry {
                A a;
            }
        }
    }
}

The error message is the following:

Type mismatch: cannot convert the expression to Class   PerformanceTestModel.xtxtuml

The code generated from effect wont compile

The xtxtuml code:

        state finalstate {
            entry {
                if ((this->PerformanceTestModel.AB.a).isEmpty()) {
                } else {
                    PerformanceTestModel.A a = (this->PerformanceTestModel.AB.a).selectAny();
                    unlink(PerformanceTestModel.AB.a, a, AB.b, PerformanceTestModel.B.this);
                    a.childTerminated();
                }
                delete(PerformanceTestModel.B.this);
            }
        }

The generated code:

    public class finalstate extends StateMachine.State {
      @Override
      public void entry() {
        Collection<PerformanceTestModel.A> _ralfassocnavexpression = this.assoc(PerformanceTestModel.AB.a.class);
        boolean _isEmpty = _ralfassocnavexpression.isEmpty();
        if (_isEmpty) {
        } else {
          Collection<PerformanceTestModel.A> _ralfassocnavexpression_1 = this.assoc(PerformanceTestModel.AB.a.class);
          PerformanceTestModel.A a = _ralfassocnavexpression_1.selectAny();
          Action.<PerformanceTestModel.A, PerformanceTestModel.B>unlink(PerformanceTestModel.AB.a.class, a, PerformanceTestModel.AB.b.class, B.this);
          a.childTerminated();
        }
        Action.delete(B.this);
      }
    }

Where this should be qualified but it isn't.

Reduce reflection in txtUML runtime lib

Goal: speed up execution.

Write user doc for 0.2.0 release

In the wiki: http://txtuml.inf.elte.hu/wiki/
Use page names prefixed with: 'v020:' (See the doc pages and page names of the v011 release.)
Do not link these pages yet.
Create a folder called 'v020' in the media manager and add screenshots there.

Poor diagram generation error messages

Error messages currently show an exception and duplicated clarification.

Should be more user friendly.

Unusable diagram generated in case of contradictory diagram definition

In case the diagram definition is contradictory or the algorithm cannot solve the problem of overlapping boxes, the resulting diagram contains all boxes on top of each other.
In this case, the problematic boxes should be placed at empty locations, eg. under the rest of the diagram.

Updating editor state has encountered a problem

This error came up after silent exceptions started to appear in bigger numbers.

I was editing this code fragment:

                PerformanceTestModel.Forward sig = getSignal(PerformanceTestModel.Forward);
//              if (sig.nf % 4 == 0) {
//                  createChild();
//              }
                if ((this->PerformanceTestModel.AB.b).isEmpty()) {
//                  
                } else {
                    send new Forward(0) to this->PerformanceTestModel.AB.b;
                }

Overlapping phantom boxes

If more than one phantom boxes are overlapping, an error message is shown. The algorithm should allow phantoms to overlap with any boxes, including phantoms and visible boxes too.

Misplaced open curly brace

When creating a new JtxtUML/XtxtUML model, the open curly brace of the model is not separated with a space.

class a extends Model{

}

model a{
