Implement representation of symbolic expressions in Smalltalk syntax

[swinkler]

Created branch in r4803.

[swinkler]

Corrected references and post-build events in r4804.

[swinkler]

As discussed with swagner and mkommend, we will implement an interface for tree formatters and a view in which the user is able to choose from all available formatters. We will also create a new project for all tree formatters except the default formatter (which stays in the SymbolicExpressionTreeEncoding project).

[swinkler]

Added interface and founded new project for formatters in r4820.

[gkronber]

I think it might be more appropriate to have formatters in problem plugins as the semantics of symbols are actually problem specific. In the encoding only terminal and non-terminal symbols can be distinguished.

[gkronber]

Please implement the formatter in the new folder called "Formatters" in the plugin "HeuristicLab.Problems.DataAnalysis".

Create the folder in this directory: ​https://dev.heuristiclab.com/trac/hl/core/browser/trunk/sources/HeuristicLab.Problems.DataAnalysis/3.3/Symbolic

[swinkler]

Worked on Smalltalk representation in r4820, r4821, r4822, and r4823.

[swinkler]

Renamed branch in r4829.

[swinkler]

Worked on the display of results of formatters in r4840:

• Renamed solution in formatters branch
• implemented view for display of symbolic expression trees as strings depending on the chosen formatter

[swinkler]

Improved management of formatters in view for display of symbolic expression trees as strings as discussed with mkommend in r4842.

[swinkler]

Minor update regarding files that should not be under version control in r4843 and r4844.

[swinkler]

Removed obsolete project for symbolic expression tree formatters and (re-)added DataAnalysis project in r4858. Minor update in r4859.

[swinkler]

Added Smalltalk formatter in r4861.

[swinkler]

Added first complete version of Smalltalk formatter in r4868.

[swinkler]

Fixed bugs in r4869.

[gkronber]

r4900:

• Added string formatters for GraphViz and LaTeX formats.
• Set svn:ignore properties

[swinkler]

Removed attributes Storable and StorableClass from tree formatters in r4906.

[swinkler]

Corrected name and description of Graphviz formatter in r4966.

[gkronber]

Added build.cmd script, and adapted .frame files for new release with r4967.

[gkronber]

Moved graphviz formatter into symbolic expression tree encoding plugin with r4968.

[swinkler]

Updated projects in exporters branch reacting on recent changes in the trunk (.NET 4.0, changes in interface of dataset) in r5180.

[gkronber]

Parts of the changes tracked in this ticket have already been released. The remaining changes should be integrated into the trunk to finally close this ticket.

r9647: copied smalltalk formatter from branch

[gkronber]

r9648: copied GraphViz formatter from branch

[gkronber]

r9649: fixed compile errors in Smalltalk and GraphViz formatters

[gkronber]

• GraphViz exporter works fine.
• Semantic correctness of Smalltalk exporter must be checked.

[gkronber]

r9794: adapted smalltalk exporter to match interpreter semantics

[gkronber]

r9795: deleted branch for data-analysis extensions as the smalltalk, MATLAB and GraphViz exporters have been integrated into the trunk

[mkommend]

Reviewed GraphViz and Smalltalk formatter for symbolic expression trees. I have tested the GraphViz formatter with an online dot engine and it seems to work fine. However, I could not test the Smalltalk exporter.

Review comments:

• The default formatter should be used when the textual representation of a model is opened.
• The namespace of the GraphViz formatter does not adhere to the coding standards.
• Remove unused using in the GraphViz formatter.
• The namespace of the Smalltalk formatter is completely wrong.
• The Smalltalk formatter does not support all available symbols.

[gkronber]

r9821: made changes as suggested in the review comments

• initially select default string formatter in the symbolic expression view
• renamed smalltalk formatter and fixed the namespace
• fixed namespace of GraphViz formatter
• removed unused usings
