Wrap the code inside an operation

[gustavo-hms]

The Ruby Code Editor (http://extensions.sketchup.com/en/content/ruby-code-editor) has an option (its a default one actually) to wrap the entire edited code between a start_operation and a commit_operation. This way one can run the code in the editor and undo it with a single undo.

It would be nice if this extension could also provide this option. It would improve its usability.

This feature has also been here for a very long time (console.rb#L205), but it is currently not exposed in the UI because it needs to be rethought:

• Is it really useful, do people actually use it? (from you request, yes)
• Architecture-wise, it would need dependencies to classes that it should not have. I would prefer to swap it out into an extension ("feature class") instead of having it in "console.rb".
• How to represent the operation in the undo menu with a distinguishable, meaningful name?

It is indeed useful. Suppose I run a code that does, say, 1000 copies of a group and put them in a grid. If I then realise that the gap between them is just too small, I need to undo the operations, adjust the parameters and then rerun the code. But undoing 2000 operations is very tedious, if not unfeasible.

Regarding the representation of the operation, I don't have the perfect answer, but maybe we don't need to find a detailed representation; maybe something like “Undo Console+ code run” or “Undo Console+ operation” is good enough.

An issue in the previous version was that someone using the console is likely to emit many commands (some of which even don't modify the model). When navigating the undo stack backwards they should be distinguishable. I had solved it by adding a counter in the operation name, which was not very meaningful and not elegant in the code. It is a feature and not a core responsibility of the console, so I need to figure out how to best implement it using the feature system and keep the core console class as lean as possible (to avoid bloat).
