I would like the current folder tab to automatically update whenever I open a new .m file in the editor. So the current folder tab will always be open to the folder of the file being displayed in the editor. Is this supported in Matlab? I know Visual Studio has a feature like this.
MATLAB doesn't do that. Perhaps this might be close enough for you though: if you enable the Document Bar in the editor (if it's hidden, go Desktop menu->Document Bar->Bar Position->Select a Position). Now open a file in the editor. If you right-click on its element in the Document Bar, there's an option to change the current folder to the location of the file. So not automatic, but only one click away.

What I'm looking for seems to be such a basic thing that I'd expect it to be managed by some setting, but I can't find it.
When I click on a file name in the file explorer, the file opens correctly, but the cursor focus remains in the file explorer. I'd like it to automatically put the cursor in the file editor.
In Visual Studio Code, whenever I close a file, the next open file becomes active in the editor and the Side Bar moves to that file's location in the folder structure. This is usually not the behavior I want. I often want to open another file in the same location as the one I just closed, but now my Side Bar has shifted around to what could be a totally different place in a large project.
I like the behavior of the main Visual Studio product where the Solution does not automatically shift. Instead, if I want to see where in the solution a file is, I can use a keyboard shortcut to move there ("Find File in Solution"), instead of automatically moving there every time the active file changes.
Is there any way to change/disable this functionality in VSCode?
The is an option explorer.autoReveal in settings (either user or workspace) which controls if the explorer should automatically reveal files when opening them.
Open VS User Settings (Preferences > User Settings). This will open two side-by-side documents.
Add a new "explorer.autoReveal": false setting to the User Settings document on the right if it's not already there. This is so you aren't editing the Default Setting directly, but instead adding to it.
Save the User Settings file.
in Version: 1.42.1
Open VS User Settings (Preferences > User Settings).
Search for "explorer auto reveal" without quotes.
Now uncheck the checkbox.
There is a new setting in v1.46 that will select the files in the explorer but not scroll to reveal them:
We have introduced a new value focusNoScroll to the
explorer.autoReveal setting. For this value Explorer will
automatically select files when opening them but will not reveal them.
from v1.46 release notes.
So that setting will highlight the active editor in the explorer but not scroll to it.
I clicked something or accidentally drug a file that was open in the editor and now it is no longer displayed.
If I double click on the file in Package Explorer it doesn't show in the editor like it used to. I have looked all over and can't figure out how to get this file back in the editor.
I thought clicking File - Open File would do it but that displays an open file dialog.
Another way to simulate this is to put the cursor in the editor for an open file and select File - Close. This closes the file but then if you double click on the file in the Package Explorer it doesn't open it in the editor anymore. How do I get these files to display in the editor again?
I also tried right clicking on the file and selecting "Open". This does not display in editor either.
I also tried right clicking and selecting "Open With Java Editor". This does not work either.
If I clicke "File" and then the name of the file in the MRU list . This does not work either.
Also, double clicking a file in Package Explorer fails to open any file. The file shows in the File MRU list but does not display in editor. Can not figure this out.
Also, if I select "Back to" or "Forward to" arrows on toolbar, it tracks the file in the Package Explorer by highlighting it but the file does not display in an editor like it used to.
Also, I have tried "File Open" browsing to the physical location and selecting it but that does not display in the editor either.
I had to open a new window (Window - New Window) and then Reset Perspective (Window - Reset Perspective) to get the editor back. Not sure why but I lost some of my perspective settings doing this.
In Package Explorer, instead of double-clicking on the file, try to right-click it and you should get several "Open with..." options; choose the one that matches the editor in which you want the file to open.
Your choice will also be saved as the default, so the next times you can just double-click and it will open in that same editor.
If you are customizing the perspective, then saving perspective could be a safer option to avoid such glitches.

I'm new to RubyMine 7 on Mac.
I used to use Sublime Text 3 and I love RubyMine so far except its lack of file previewing.
In Sublime Text, when clicking a file in the sidebar (file explorer), the selected file content shows in an editor tab for temporary viewing.
If I select another file, then the same tab changes to the content of the newly selected file.
I've been searching for this preference setting in RubyMine, or in a plugin, but I've had no luck.
A similar feature is "Autoscroll to source" but this feature opens files rather than previewing them.
If anyone knows how to do Sublime Text-like file content previewing in RubyMine, I'd appreciate it.
RubyMine doesn't have a feature exactly like Sublime Text file previewing.
The Quick Definition action can sometimes meet the same need. When invoked on a file, it opens a popup with the file's contents. You can invoke it on a file in the Project or Find pane and probably other panes, dialogs, popups, etc. that list files. (You can also invoke it in an editor on an identifier such as a class, module, or variable; it will show the code that defines the identifier.) Invoke Quick Definition with ⌥-space or ⌘Y in the Mac OS X 10.5+ keymap; use ^⇧I on Windows or check Preferences → Keymap for other keymaps, or use ⇧⌘A qd ⏎. Hit Escape or click outside the popup to close it.
When you invoke Quick Definition on a file in the Project pane and navigate to other files in that pane (with down and up arrows to move between files, and right and left arrows or Enter to open and close directories), the Quick Definition popup will stay open and update to the currently selected file, which is relatively close to Sublime Text file previewing. You can also hit Enter to open a file, F4 to open a file and move focus to the editor, edit the file, ⌘1 to jump back to the Project pane, etc., all with the Quick Definition popup still open, until you choose to close it.
If that isn't close enough, there are two feature requests for Sublime Text-like file previewing in JetBrains IDEs which you can vote for:
Preview currently selected file in project window
File Preview features from Sublime
If I've got a file open in Eclipse, how can I figure out where it is on the filesystem?
For example, in Vim I would use :pwd.
Use the Eclipse menu:
File->Properties
or the shortcut:
Alt-Enter
You should be able to see the Location associated with the Resource
Just hit Alt-Enter.
The other solution ("File-->Properties" or "Alt+Enter") didn't work for me.
I use:
Right Click (in current editor) --> Show In (shortcut: Alt+Shift+W) --> Project Explorer
This shows in Project Explorer the location of the file. If the file is a class in a referenced library, the dependency tree is automatically opened.
What you're looking for is the 'Properties' dialogue for the current file. This can be activated in two ways:
Selecting from the menu: File -> Properties
Using the shortcut: Alt + Enter
This gives you a dialogue which contains both the full path of the document, as well as the relative path from the workspace root.
The dialogue can be quite handy: it allows you to highlight and copy the file path.
Linking to Project Explorer won't work if you have many files - it will select the right file in the list, but it won't "scroll" to that portion so it is visible.
You'd have to manual scroll the Project Explorer view to see where the file is. It could also be nested so deeply that the full location will be obscured by truncation.
Another way to quickly (keyboard-free) see the path is to hover over the file type icon (on top of the open editor window).
Eclipse also has the ability to link the explorer view with the current file, so that whenever you change a file, it is expanded and selected in the explorer view.
Just look for the following image at the top of the view:
