Fast way to find Javascript source file in debugger? - google-chrome-devtools

RStudio uses Chrome Devtools for debugging support in its Viewer pane. (It is labelled as "RStudio Devtools", but I'm not sure to what extent it is customized besides that). You can open its window using Right-click "Inspect Element".
When developing a display that uses Javascript, the source pane in Devtools is very useful for setting breakpoints, single stepping, etc.
One thing that is fairly inconvenient is finding the line where I want to set a breakpoint. Once I have the source file open searching it is easy, but getting to the right source file is hard. Typically after I go to the source pane, I see something like this:
I know the name of the file I want to debug, but it's buried several levels below index.html in the list of files on the left. Is there a way to quickly search this hierarchy of files for a filename, so that I don't need to open all the levels down to the file I want? For example, I might want to debug htmlwidgets.js:

You'll note in the "sources" pane that, if you have no open files, you'll see a message in the middle that indicates you can type Command + P (or Ctrl + P on Windows/Linux) to open a file. When clicked, this will open a text box that will fuzzy search across the names of all source files. Type the filename there and it should be in the first results. You can navigate to it with the keyboard and select it with <Enter>/<return>, or simply clicked with the mouse.

VS Code - search for two different things in two files

In VS Code how do I search for one thing in one file, while at the same time searching for a different thing in a different file?
Using the normal Find when I try to search for something in a second file it overwrites any find I am doing in a previous file.
I see that the Search functionality enables me to open a search in an editor, but this functionality doesn't seem at all useful to me.
There is no obvious way to run a search on a specific file short of manually copy/pasting the file path into the advanced search options.
The editor that the search results open in contains adjacent context lines, which if you have a large number of results makes it useless as a simple list of search hits.
The editor that the search results open in is not editable, making it useless as an editor.
I need a list of results for each of two searches on two files.
Item 1 can be handled with an extension I wrote: Find and Transform. You could make a keybinding that opens the Search Panel with the current filename (or any file/folder/etc.) added to the files to include input. Actually I added a context menu command to the editor, or any editor tab or an editor in the Explorer to do just this.
Item 2. The search editor number of context lines is configurable and will remember your last setting.
Item 3. There is an extension, Search Editor: Apply Changes which can apply any changes you make in a search editor to those files.

Can't edit files in Vscode

I've just started using Vscode and have a created a WebAPI project. On trying to open any of the default code files (Startup.cs and Program.cs) whatever I type starts to appear in the blue bar as shown below instead of where I have placed the cursor. I have no idea what's going on or what that blue bar is.
I am able to add my own code files and edit these as I would expect.
I'm running Vscode 1.29.1 on Win 10 on a Dell Latitude 12 7275. The vscode extension
Enabled extensions :
That's caused by Vim extension. Uninstall or disable it, otherwise use insert key on your keyboard to put it in insert mode.
I'l leave this here for future readers
Basically, if I split files in tabs in VS Code, I could work with the files on the left hand side but could "read-only" all the files on the right hand side.
When I went to the extensions tabs I noticed that whatever I typed was being typed in the field in the extensions search bar. After deleting that, and clicking back on the "Files" tab, it went back to normal and can basically edit files on the both sides of my split screen.
If cannot type
Check where whatever you type is going (e.g. Extensions > Search bar)
Delete wherever it's being typed, and click back on the "Files tab"
Check if it works
I had to change the parent folders permission...
Try changing the entire folder to:

Visual Studio Code - Tabs (editors) of the same project in multiple screens

Using multiple screens I normally place multiple classes (files) in different screens, this helps me a lot while refactoring, checking tests and comparing changes.
Visual Studio Code does not allow me to drag a tab outside the window and view it in (for example) another monitor.
I checked the documentation and plugins, but the only way I found, is to open two windows, pointing to the same project (folder) and put those in different screens.
I don't like this solution, that causes also some problem when I watch code changes using TypeScript.
Any suggestion?
I use Windows 10, latest version of VSCode.
A solution is to press CTRL+K and after releasing CTRL, press O.
This will open the current file in a new window.
There are few things I don't like about this solution:
- Drag and Drop does not work
- Create a new instance of VS Code resulting in (for me) 180MB of ram used
- To open the file it takes to me few seconds (quite slow)
- The file remains open in the original window as well
Update 20/03/2019:
There is a feature request you can track here:
https://github.com/Microsoft/vscode/issues/10121
And an explanation about why this is difficult to implement here:
https://github.com/Microsoft/vscode/issues/10121#issuecomment-345770248
Update 20/03/2019:
Another important side effect highlighted by #Mär is that:
the IntelliSense fails to establish references it had when the file
was opened in the window, where the entire project is opened
The easy way but with the same drawbacks. More ram and resources will be used. Is to wrap your project in a folder.
It's the best possible thing. As by now!
=> Duplicate the workspace.
Open the command pannel ctrl+shift+p or F1.
Then write dupl
You'll get that
That's it.
More
If you want to add more folder to the working space.
=> go to File then Add Folder To Workspace
You can add as many as you like.
 Also better more
You can open a new window (ex: ctrl+n)
And then go File > Add Folder To Workspace.
And start adding folders to your new Workspace. You can add any folder, that is already open or not. That's too way great. You can have all the needed folders for example in the second screen.
A little hack I used is to just stretch the editor window to fill both screens and split the view pane between the monitors such that both screens show just one open file.
This is a cheap hack that works without opening multiple instances of VSC.
It may not be the proper solution, but it works without eating up all my system memory.
I found the following way to work on multiple monitors (important: they must be the same size and resolution):
open a visual studio in windowed mode on the 1st monitor (in my case it is a left monitor)
move the window to the (left) top corner
stretch window to the 2nd monitor (right) bottom corner
split screen by clicking “split editor” several times
move the code sections separator to the edge between the monitors
This is old qestion, but such way can be useful for someone. It is not very convenient, but it works. The solution may have already appeared in the VS itself, but I didn't find it.
Visual Studio Code does not allow me to drag a tab outside the window and view it in (for example) another monitor
Actually, VSCode 1.57 (May 2021, 4 years later) will propose something close:
Improved editor drag and drop across windows
Support for dragging editors to other windows was improved in this release. You can now drag diff editors, custom editors and the entire editor group to another window to open the editors there.
My solution was to use Remote-ssh to connect to self and open in another window. This does take extra resources. But I find this comfortable as I don't need to create additional workspace.
For me on Ubuntu the solution was to create a project folder symlink and ope it in a new window (as it won't open the same folder in another window)

Multiple editor windows with multiple tabs

Very often I work with multiple projects in MATLAB and have a group of files for each project that I access at one time. Having all files of all projects open causes a lot of clutter in the workspace. One can do this for one single set of files by docking which is well known.
Is there a way to tab projects, or have multiple MATLAB editors (for each project) open with multiple tabs in each (with the projects files). The question can be found here too. In the same vein, are there other code editors which can be used to perform the same?
Project1
file 1.m
file 2.m
file 3.m
file 4.m
Project2
file 1.m
file 2.m
file 3.m
file 4.m
Either in the same window, or in different windows.
Unfortunately I don't believe MATLAB can do that kind of project/file management for you, which is why I use Sublime Text 2. It's perfect for that kind of project/file management... and not to mention the awesome shortcuts and quick editing tools to help you code faster.
Check them out: http://www.sublimetext.com/. The one drawback is that it's nagware. It is free to use, provided you can bare the popups to buy a copy of the software every now and then. Once you buy it, the popups go away. Give it a try and see how it goes!
If someone still need a solution for that-
You can just drag a tab of one file to the side, or bottom of the space of the editor, like that:
And the result will be:
Now you can drag in the same way other tabs to the new tabs group, and you have two separate tabs groups (but one Editor window..). You can of course drag the middle edge line to the right-end, and work fully only with the first group, or drag it to the left-end and work fully with the second one.
Note for one drawback here- if the line is in one of the ends, you don't see the tabs status and files names of the hidden group, and if you forget that you opened some file there and try to open it again, you will not see it opened, or any change in the IDE, because the control goes to the already opened tab but you not see it.

Show the name of the containing folder in the Eclipse tab of a file

I have the same set of files in N folders, one of them, say, blank.xhtml. The files contain somewhat similar information and it is becoming overwhelming to figure out which file comes from which folder every time I switch between the tabs. When I open one of them to edit and happen to open a file with the same name from another folder I get confused and more often than not end up editing the wrong file: nullifying my hard work. So I am wondering if there is a way to show the name of a containing folder in the tab like this G-06/blank.xhtml or G-07/blank.xhtml. I will be very very thankful to anybody who has pointers to how I can make this happen.
As an addition to the Maroun's answer there is an alternative solution.
It's not exactly what you want (full name in the tab's title), but may be useful sometimes.
In the "Project Explore" view (the same goes to "Navigator" view) click the "Link with Editor" button. That way, whenever you choose some file opened in the editor, it will be automatically selected/highlighted (see the picture) in the "Project Explorer" view.
Here is the picture:
Maybe this will be useful to you too.
If you hover the mouse over the tab containing the file name then a popup appears showing the full path. Not exactly what you wanted, but it should help. (This with Eclipse Neon.3 Release 4.6.3 on a Mac).
Not quite what you're looking for, but ctrl+shft+e will open the switch editor window that shows all the open editors with their filepaths. I use this shortcut for the same reason. I'll have multiple build.gradle files open from multiple projects and this helps pick the correct one
