ProgrammableOperator Overhaul

[epitzer]

Quite a number of tickets have accumulated concerning the programmable operator (#607, #179, #450, #173, #482). In a complete overhaul these bugs should be addressed.

[epitzer]

Add SharpDevelop libraries to support syntax highlighting and code completion (r2685)

[epitzer]

should be (r2658)

[epitzer]

Add new Plugin that provides a code editor with syntax highlighting and code completion (r2659)

[epitzer]

New ProgrammableOperator with syntax highlighting, code completion, configurable assemblies and namespaces (r2660)

[mkommend]

corrected SharpDevelop plugin r2661

[epitzer]

Ensure proper resizing of CodeEditor and don't crash when removing non-existent assemblies (r2667)

[epitzer]

Group assemblies by plugin and replace assembly and namespace list boxes with tree views (r2668)

[gkronber]

Fixed incorrect reference to PluginInfrastructure with r2670.

[epitzer]

Add InvokeRequired in Dispose method to prevent cross-thread access exception (r2672)

[epitzer]

use SharpDevelop's TextArea.KeyEventHandler to prevent editing before Prefix and after Suffix (r2673)

[epitzer]

Filter out generated assemblies during discovery (r2678)

[epitzer]

statically initialize list of assemblies and plugins (r2679)

[epitzer]

keep namespace treeview node expansion and expand newly added namespace nodes (r2680)

[epitzer]

also allow sub namespaces that don't contain any types (r2681)

[epitzer]

try a different method for signaling the parser thread to terminate (r2719)

[epitzer]

disable elements while updating (or compiling) (r2720)

[epitzer]

check temp path, and disable code completion persistence in case of file permission problems (r2762)

[epitzer]

properly close test file and explicitly catch all possible exceptions (r2765)

[epitzer]

towards migration of ProgrammableOperator to HL 3.3 (r2799)

[epitzer]

further steps towards migration of ProgrammableOperator to HL 3.3 (r2877)

[epitzer]

Finished initial port of ProgrammableOperator to HL 3.3 (r2897)

[gkronber]

Fixed plugin dependency in programmable operator plugin with r2978.

[epitzer]

adaptation to HL 3.3 (r3008)

[epitzer]

Correctly update displayed method signature if operator parameters change (r3014)

[epitzer]

Change Project references (r3056)

[svonolfe]

Added check to ProgrammableOperator if the ApplicationManager exists so it can be used outside of HL in r3234

I wanted to add two more issues encountered when I was using the ProgrammableOperator recently:

1. The parameters cannot be set.
2. Using the parameter "context" easily results in missing references.

Regarding 1.: The Execute method signature contains the values of the parameters, but not the parameters themselves. This means that if I design a custom evaluator with a Quality parameter, the value will be null (Quality is not yet available) and it cannot be set through (typically) QualityParameter.ActualValue = ... as only the value is given in the signature. It would be better to have the parameter itself in the method signature instead of its ActualValue.

Regarding 2.: E.g. the simple line "int count = context.Scope.SubScopes.Count;" requires that I add HeuristicLab.Collections.ObservableList as well as System.ComponentModel.INotifyPropertyChanged. I would suggest including a bigger set of assemblies that are loaded by default.

There are also a few usability issues (from my point of view):

1. There is no indication of what the two tree views on the left contain. A label "Assemblies" and "Namespaces" should probably be included.
2. The first tree view lists all HeuristicLab plugins/assemblies first and groups everything else under "other", while the second tree view lists all other namespaces first and then groups the HeuristicLab ones at the end. It would be better if both lists had the same grouping and order.
3. No text can be entered in the line just above "return null;", but tab, backspace, and return do work.

[epitzer]

Incorporate changes suggested by abeham in comment:28 (r3903)

• Fix persistence of selected assemblies
• Fix problem with static initialization
• Make parameter values (ActualValue) with parameter object
• show (or hide) parameter namespaces as necessary
• add icons for buttons, assemblies and namespaces
• sort assemblies and namespaces alphabetically
• correctly mark and unmark select assemblies
• put assemblies and namespaces into group boxes

This ticket spans prerelease commits as well as postrelease. I'm closing this as released under 3.3.1. Any issues concerning the programmable operator should go into own tickets. #173 is still left open, I don't know what to do with that.
