Intellij: add space after double slashes in line comment

问题

Is there a way in Intellij IDEA (I'm using version 13) to automatically add a space to line comments between the two slashes and the text:

If I enter :

//This is a comment

I'd like to get the following when I run a code reformat (Ctrl-Alt-L on Windows)

// This is a comment

It's for Javascript files but should be working for other file types.

回答1:

If you press CTRL / or CMD / it will put // at the beginning of the line and the comment will be properly indented.

//        comment with two indents

For this to work Comment at first column must be checked in Editor->CodeStyle->Javascript->Wrapping and Braces->Keep when reformatting like mentioned in another answer.

This screenshot is for Java, but it works the same for Javascript. Just choose javascript in the menu

If you want to write multiline comment you can use CTRL SHIFT / or CMD SHIFT / That way when you go into new line, you will have one space after the comment start

    /*
    * there is space before this*/
