outdentCurrentLine isn't implemented

[reznikmm]

It seems outdentCurrentLine not used anywhere in the code and so it doesn't work as described in documentation:

Defined in monaco.d.ts:4678
Describe whether to outdent current line.

monaco-editor version: 0.14.3
Steps or JS usage snippet reproducing the issue:

I've tried this configuration without success

                    {
                      beforeText: /^\s*(?:begin|private)/,
                      afterText: /\s*$/,
                      action:{
                        indentAction: monaco.languages.IndentAction.IndentOutdent,
                        outdentCurrentLine: true, appendText: "2"
                      }
                    },

👍 We should remove it from the EnterAction

Is it difficult to implement it instead of delete? I find it very useful for Ada formatting.

If you provide some direction I could try to implement it.

I actually don't know of the top of my head why we had it in there. ping @rebornix maybe you remember, did we use to support that, or was it just added by accident ?

Can you suggest how to implement auto indentation without IndentOutdent for such Ada constructs:

package Pkg is
   A : Integer;  --  Here indent is 3
private  --  indent 0
   B : Integer;   --  Here indent is 3 again
end Pkg;

procedure Proc is
   A : Integer;  --  Here indent is 3
begin  --  indent 0
   null;   --  Here indent is 3 again
end Proc;

Ada has a lot of such constructs. I would define IndentOutdent for begin and private and this should work automatically.

@reznikmm I would start with using indentationRules -- https://github.com/Microsoft/vscode/blob/2a891803f19ddd80affce9eecf7b293c913d1a61/src/vs/editor/common/modes/languageConfiguration.ts#L84:L105 and enabling the autoIndent option.

But @rebornix is the real expert on this area.
