Auto-Identation and Switch Statements

[jdiehl]

I noticed that the auto-indentation seems to be confused after switch statements. Consider the following (JSLint-approved) code:

function foo(a) {
    "use strict";
    switch (a) {
    case 1:
        break;
    }
}

When hitting enter after the first closing }, auto-indentation inserts 3 tabs (1 would be correct).
When hitting enter after the second closing }, auto-indentation again inserts 3 tabs (0 would be correct).
This goes on, even if additional functions, scopes, whatever are defined, auto-indentation always adds 3 tabs.

I get 2 tabs after both closing curly braces instead of 3, if this is the only text in the file.

This is a CodeMirror bug that repros outside of Brackets as well. I've filed codemirror/codemirror5#708 to track it.

Looks like the CodeMirror bug has been fixed. It might be a while before we can merge though, since there's been a lot of churn in the scrolling code lately. @jdiehl, do you want to verify the fix upstream in the meantime?

[jdiehl]

This works on CodeMirror.net, so I guess it is fixed. Thanks for forwarding this.

Reopening -- this won't be fixed in Brackets until we integrate a newer version of CodeMirror

Marked low priority

The worst of this appears to be fixed now that cmv3 is merged--the indentation doesn't "march inward"--but the indentation level of the case statement is too high (it gets indented two tabs worth instead of one, at least when spaces are on). Assigning to me

Filed codemirror/codemirror5#1592 on the latter issue.

This is due to the overriding of electricChars on the Editor.
CodeMirror javascript mode double indent every line in a switch statement except the one with case and default at the beginning.
The problem is that in JavaScript Mode the ":" is an electric char (which is not the case of the _checkElectricChars hardcoded RegExp), so in CodeMirror when you type ':' the indentation on case or default lines are updated, what does not happen in brackets.
I guess a simple fix would be to include the ":" in the _checkElectricChars methods. (in fact does this _checkElectricChars methods could be removed ?)
