Feature request: Support the Scala Editor

[hrj]

I see that you have special plugins for Java, Python, etc. So I wonder whether a spearate plugin for Scala is required. The Scala editor from http://scala-ide.org/ mostly works fine. But some things don't work sometimes. For example, folds are not opening in a file for me. Or Ctrl-O to open members of a class, doesn't work, sometimes.

Thx!

I just realized, opening folds is having problems even with mouse actions. So that is probably a Scala editor bug rather than something specific to vrapper.

What are you requesting here? The reason we have Java and Python plugins is to create a number of default mappings for those languages, the editor itself should be supported out of the box.

I'll give it a try later on, but in theory we can't do anything about Ctrl-O failing (there could be a bug, but then you'd have to point to real Vrapper errors).

But again, what features would you expect in a Scala language plugin that Vrapper doesn't do yet? Please be specific as I'm not using Scala. In the Java plugin for example, we currently map gd and gD as "Go to declaration", gr and gm to open the Refactor / Source menus. We bound = and gc as operators to do indenting and toggle comment on text objects. We could do the same for the Scala editor if there are corresponding Eclipse commands, but then you would need to give them to me.

If the only thing that the language plugins do is support language specific features, then I don't have anything specific to request for Scala. I have used Vrapper mostly as a langauge-agnostic editor. (Good to learn that gD has special behavior in Java).

I thought the language specific plugins help overcome the quirks in that language's editor. So, I thought, a Scala specific plugin would help remove the quirks / bugs that I encounter while using vrapper with .scala files.

If the type of editor doesn't matter to vrapper, I can file the bugs I encounter when editing Scala code as generic vrapper bugs. Else, I will report them as Scala specific bugs in this tracker.

So is there any remaining feature request or defect here? Should I just close this issue?

For future reference, here's what our current language-specific plugins do:
http://vrapper.sourceforge.net/documentation/?topic=optional_plugins#programming
They do nothing more than define mappings to Eclipse operations which are specific to the language.

TLDR: There is no defect remaining. I am closing this.

Thanks for the clarifications.

I found one reproducible problem with folding in Scala editor using the Vim folding commands. But I later found that it is also reproducible without vrapper, using Eclipse folding shortcuts. I will report this to the Scala editor directly. If anyone is interested, here are the details:

• Eclipse Luna + latest Scala IDE (4.0.0.v-2._11-2015)
• Create a scala project and open any .scala file for editing
• zM or Ctrl Shift Numpad - to fold all
• Try to open a fold with zo or Ctrl Numpad +. This fails on first attempt but works on second attempt (for every fold).
