Emacs code to automatically set indent-tabs-mode according to existing code
When I'm editing old files in a group where other people may work on them tomorrow or ten years from now, I like to adopt the file's existing tab or space indentation scheme for my additions/changes - that's just being polite, but it's currently something of a hassle. Does anyone have a way for emacs to look for the current indentation scheme in the file or at least the neighboring lines and use that for Tab indentation?

The following sound promising:

A comparison/review would be interesting.

I tried searching what this option is. But couldn't find.
It's showing changes vs. your committed code. The option is "SCM: Diff Decorations Gutter Visibility". SCM = Source Control Management, a.k.a. git.

The code in Vscode is not entering a new line on auto as I write across. It just keeps going sideways making it hard to see all the code.
Go to View then enable Word wrap.

Is there a way in Visual Studio Code to have multiple instances of the same file open, but without splitting the view?
(Sublime editor achieves this with "File > New View Into File")
Just press the icon next to the ... Icon (It looks like a split window), or press Ctrl + \*. I hope this answered your question! :D
Edit: Sorry, I didn't read the whole thing since I came to this post from the best text editor article, lol. I don't think there is a way of doing that. Though I think you can make it yourself if you want to.

How to change minibuffer location in Emacs? [duplicate]

I'm tired to move my eye to minibuffer that is bottom of Emacs.
So I want to minimize eye movement. Is there any solution for this? I want something like as following.
Setting minibuf location on top of current frame.(I don't know It's effective or not. )
If I typed M-x, minibuf show up center of current frame.(I think it's effective.)
I find it helps to have the minibuffer always in the same place on my screen --- IOW, a standalone minibuffer frame. Yes, that involves eye movement, but always to the same place. You might find that this helps. See library oneonone.el for an implementation that is easy to try.

Scroll outside or below content in Eclipse [duplicate]

How can I get Eclipse to scroll past the bottom of the document?
(1 answer)
Closed 5 years ago.
I would like to be able to scroll further down in Eclipse, below the last line of content in the file.
A lot of editors/IDEs support this, IntelliJ and TextPad, for instance. Vim if enabled.
It's a bit annoying having to put 20 empty lines in the bottom of every file in order for the code I'm writing to appear in the middle of the screen.
Any suggestions?
I've only found a few hits on Google, that are old. And I'm not sure what this is named, so if you have a word for it please tell, as it will help me in my search.
As it seems it's not possible at the moment, I would like suggestions on how to best overcome this issue.
Thanks.
This is a known limitation, and there is a bug opened for this - https://bugs.eclipse.org/bugs/show_bug.cgi?id=362540. You can add your thoughts to the bug.
