Describe the bug
If any file inside the project is found at 2 places just because it is copied from one dir to another dir within the project at the host side, opening both files one after another at the guest side, shows the editor name including the session URL path.

To Reproduce
Steps to reproduce the behavior:

1. Create a project at the host.
2. Now copy & paste index.html from the src dir to app dir.
3. Start a session and open index.html from both places.
4. Notice that each tab now has a long path including session ID

Expected behavior
That a short path to disambiguate would be good but without sessions.

Describe the bug
Rename on the host side is not reflected correctly.

To Reproduce
Steps to reproduce the behavior:

1. Open file in IntelliJ
2. Participant joins session
3. Host renames file
4. Browser should reflect change

Expected behavior
File correctly renamed in browser.

Describe the bug
For files that are actively open in Eclipse, we can have our generic language binding provide outline information using the same service used by the outline view in Eclipse.

To Reproduce
Steps to reproduce the behavior:

1. Open a JEE project in Eclipse
2. Open in the browser a JSP file
3. Take control and observe that there is no outline information

Expected behavior
Basic outline information should be serviced from Eclipse.

Describe the solution you'd like
Provide a way for hosts to decide permission levels of participants including modes like:

• View/follow only participants
• Automatically pre-enable seamless change of control
• Change permissions on a user-by-user basis

It would be beneficial if after joining a session, it were possible to see what local changes have been made and not yet committed to Git including diff visualization.

Describe the bug
Discovered in VS Code but likely happens other places -- if you do a search that results in lots of results, you can get timeouts trying to load files (likely channel is being thrashed with results)

To Reproduce
Steps to reproduce the behavior:
Start a vscode session & take control in the browser.
Open the search view and search for "index", or any keyword which can populate many results.
While the results are loading just Click on the result items, like 2-4 items. [Control is still there ]
Go to vscode, check the ct-view

Expected behavior
Actual: Below are the list of issues:

1. You will notice that ct-view in vscode shows the Start Session button, i.e. session is internally disconnected.
2. Status bar (vscode) at the bottom shows that the participant is still connected, however clicking on that does not open the palette so that I can end the session.
3. At the participant side, it looks like control is still there and goes after a few seconds with a flash message " Lost connection with host" https://gyazo.com/aee95f4984ae0e87e7ad7b048daaddd1 (Control is lost) which means that session is back now. [Expected: Session should be fully terminated/blocked] but actually it's not.
4. If Participant tries to take control, he sees this message Waiting to host to be idle (https://gyazo.com/3078826e1404330d6317e66019751883) & he cannot take the control.
5. To establish a successful connection, the host should have to restart the IDE to proceed further.

Is your feature request related to a problem? Please describe.
In general, when opening files we don't handle we should deal with gracefully. For images in particular, it would be great if we can render those better.

Describe the solution you'd like
Allow previewing images directly in the browser as a preview browser tab.

The people accessing the program using a web browser can only do this using Visual Studio Code.

It would be nice to have support for Eclipse (or JetBrains IDEs when they are coming) on the website too.

Update site details seem out of date or not working then bombs

Describe the bug
When working with multiple editor tabs, you can get into a state where the tab opened in a non-foreground browser (at browser level) is not fully activated and requires clicking somewhere else in the editor space to allow editing and activation events to be fired.

To Reproduce
Steps to reproduce the behavior:

1. Have 5 files open in Host
2. Connect Participant
3. Open those 5 files in participant
4. Click through files in Host some
5. Go back to Browser
6. Take control and switch through files

Expected behavior
Tabs should always become active even when opened with a background browser window.

Extra Details
The issue only happens if you have the browser non-foreground. The workaround is just to click somewhere in the editor and then the tab goes white.

The goal of this task is to provide an IntelliJ plugin to support CodeTogether in IntelliJ-based IDEs.

Describe the bug
Content Assist displays duplicate proposals for CSS files, such as multiple entries for "body-color" as seen below.

To Reproduce
Steps to reproduce the behavior:

1. Open a css file
2. add body { }
3. Inside body, type background-c and invoke CA
   Notice there are several duplicates listed, like below. Doesn't happen with other file types.

Expected behavior
There should not be any duplicate entries.

Screenshot

Describe the solution you'd like
Change the view icon to match the common styling. The icon should look more consistent with IntelliJ.

Describe your primary environment
IntelliJ developer.

Describe the solution you'd like
When you double click a file to open it, it could take about a second or two to open if it hasn't been opened before in the current session. Because of this delay, it's not clear if your double click was registered, I believe other software would show a small loading animation next to the file until it was loaded.

Describe the bug
Top-level actions for New File or New Folder should be disabled when not in control. In addition, remove "Add Folder to Workspace" entirely as it is non-functional and used only from Host side.

To Reproduce
Steps to reproduce the behavior:

1. Connect to session
2. Try to use action when not in control

Expected behavior
Actions that are not functional should be disabled or hidden.

Please ignore this content.

Just testing.

Describe the solution you'd like
Introduce visualization of control in the editor of IntelliJ, similar to how we do with VS Code and Eclipse with a simple in-editor annotation.

Describe your primary environment
IntelliJ developers.

Describe alternatives you've considered
You can use the presence view as a workaround but it isn't very visual.

Release the initial Eclipse plug-in's update site and marketplace entry, with drag-and-drop installation.

Describe the solution you'd like
Add an icon to the CodeTogether plugin for IntelliJ for better branding in the marketplace.

Currently participants in browsers don't have a clear indication if a session's host is still online. We should improve this visualization/notification including immediately making editors read-only.

Describe the bug
After inserting a selected CA proposal by pressing dot, CA is not subsequently being invoked.

This happens having either VSCode and Eclipse as hosts.

To Reproduce
Steps to reproduce the behavior:
The case is, if on browser side you type something, invoke content assist and insert the proposal by typing dot, the selected proposal and the dot are entered correctly but there's no content assist triggered after the dot (as we usually see if we type something and then just enter a dot e.g. cartItem.) and you have to invoke it manually.
However, if you do that on host side as host in control, proposal and dot are inserted and also it opens a new content assist for the proposals after the dot is inserted.

Expected behavior
Content assist should open again to offer subsequent suggestions.

Additional context
The issue is not on the host side, it's on the browser side with the participant in control. The gifs for comparison are to show how it behaves if you try the same case in host editor the CA is invoked in that case (the expected). However, if you try the same on browser side it doesnt.

Describe the bug
If a participant delete a file that is open in host, the file is closed in the host side, this provoke that host switch to next editor and participant lost control for the editor switch.

To Reproduce
Steps to reproduce the behavior:

• As host open some editors
• as participant take control
• open the file that you will delete
• delete the file.
• participant lost control since host switch editor

Expected behavior
Participant should keep control.

Describe the bug
When closing and reopening a file in the browser, the cursor location is different between the host and the browser.

To Reproduce

CASE I: vscode:

1. Start a session and get control in the browser.
2. Now open a file & add something. [Note the cursor position]
3. Save -> Close -> Re-open the file into the editor.

Actual:
At the host, the cursor position is shown by the control icon where it was last in step#2, but at browser, the cursor position is still at (0,0).
Refer: https://i.imgur.com/ggJjrXo.gifv

CASE II: eclipse:

1. Start a session and get control in the browser.
2. Now open a file & add something. [Note the cursor position]
3. Save -> Close -> Re-open the file into the editor.

Actual:
browser side: Cursor position is (0, 0) which looks expected in case of eclipse host
eclipse side: There is no control icon showing or not synced with the browser cursor position.

Describe the bug
Log shown in browser:

We're missing the following visual information in the Visual Studio Code instance that creates a CodeTogether session:

• Active participants, without starting another browser session that shows participants.
• Active controller. A visual cue on which participants currently controls the session.

Describe the bug
Control request is not invoked when the participant presses backspace

To Reproduce
Steps to reproduce the behavior:

1. Open file in browser
2. Place cursor after some text
3. Press backspace

Expected behavior
If not in control, a dialog should be presented to the user to allow taking control.

Describe the bug
A user complained that scrolling with the mouse wheel is too slow ("mousewheel is unbearable small steps"). While faster in Chrome than in Firefox, both are still too slow to be usable.

Note: I have a mouse with a optional fluid scrolling mode in which case it's probably an acceptable speed, but it still lacks the acceleration logic that you get in Eclipse.

To Reproduce
Steps to reproduce the behavior:

1. Open a session in Firefox
2. Try to scroll using mouse wheel

Expected behavior
Scrolling should be fast enough to navigate a relatively large file.

Describe the bug
Go to definition set cursor at beginning of the line instead of the direct location for the definition.

To Reproduce
Steps to reproduce the behavior:

1. Open source in IntelliJ
2. Take control from the browser
3. Navigate to corresponding source

Expected behavior
Jump to the direct location for the definition.

Screenshots
Go to definition now is taking you to the line where the var/method is but to the beginning on the line and not the the name:

Describe the bug
Rename of dirty editor from browser fails with the dialog looking stuck.

To Reproduce
Steps to reproduce the behavior:

1. Open a file in browser
2. Modify file
3. From Explorer try to rename it

Expected behavior
That the file is renamed and still dirty just like if you renamed it on the host side.

CodeTogether Host (please complete the following information):

• IDE: VS Code
• IDE Version 1.44
• OS: All
• OS Version: Any

Describe the bug
We should clean up the recent files list as it may refer to files from different workspace/project.

To Reproduce
Steps to reproduce the behavior:

1. Make changes in a session
2. Stop the session and start another one
3. In new session, see previously modified files

Describe the bug
When formatting, changes to the tab size/spacing can cause inconsistencies with subsequent editing.

To Reproduce

CASE I: Formatting applied at Browser side
Steps:

1. Apply some custom indentation settings at Eclipse at Pref->General->Editors->Text Editors. Eg. Tab Width =7.
2. Close Prefs by clicking on "Apply & Close".
3. Start a CT session & open the session URL in the browser.
4. Grab the Control & Code.
5. Open any HTML file which has a non-formatted code.
6. Invoke Formatting from the context menu in the editor.
7. Once formatting is applied compare the code from browser to host.

Actual:
There is a mismatch in the formatted structure which results in the change in cursor position of some part of the code as because formatting at participant gets applied with tab size 4 (default) & at host it gets applied with the custom settings of the ide (tab size=7, step#1)
refer:
https://share.getcloudapp.com/6qu5kG5A

CASE II: Formatting applied at the host side

1. Host: Open any file which has custom indentation applied (say tab size =6).
2. Now Start the session and open the URL in the browser.
3. By default file opened (in step#1) at host gets open in the browser.
4. Now match compare the formatted structure of the code from host to browser.

Actual: At the browser side, the formatted editor always shows the content formatted with tab size =4 by default, irrespective of what indentation tab size does the editor is having a host.

Describe the bug
Every time you see the results change, enter was pressed shortly before. I had to press enter about 3 times before I got the correct results.

To Reproduce
Steps to reproduce the behavior:

• When searching continue typing and hitting enter to filter
• Observe that results can include previous/invalid results

Expected behavior
Results should be refreshed on filter change to show only matches that are still valid and continue refreshing from host.

Screenshots

Publish the initial VS Code extension to the VS Code marketplace and download page.

Describe the bug
When leaving a CodeTogether session, a message is shown about unsaved changes being lost. If the participant is not in control, this dialog should never be shown.

To Reproduce
Steps to reproduce the behavior:

1. As host, open some files and make changes
2. In participant watch host, and then try to close tab

Expected behavior
The tab should allow simple navigation away without dialog

Describe the bug
Previous selection is not restored when reopening a file.

To Reproduce
Steps to reproduce the behavior:

1. Host opens a file.
2. Host selects the last line.
3. Host closes the file.
4. Host reopens the same file.
5. The cursor shows in browser side at start of file.

Expected behavior
Participant sees the last line is selected.

Describe the bug
By default IntelliJ is saving changes by default however dirty state is not accurate in browser

To Reproduce
Steps to reproduce the behavior:

1. Open file in IntelliJ
2. Connect and watch from browser
3. Take control and make changes

Expected behavior
The editor should not show dirty as it is auto-saved on IntelliJ side but shows dirty.

Describe the solution you'd like
The goal of this task is to provide the same support as in Eclipse in that you can directly make an account from the IntelliJ plugin without needing to go the web page.

Describe the solution you'd like
When a participant start a session ask IDE for Recently Modified so that the initial state is consistent with what has been done so far in the session.

Describe the bug
Using Go to def to jump to a file in node_modules closes current active editor on host

• Works fine with CodeMix
• With VSCode, it works fine if I jump between components but results in below issue if I jump to a module.

To Reproduce
Steps to reproduce the behavior:

1. On VSCode import an angular project
2. Start a session
3. Join as participant
4. Take control as participant
5. Open app.module.ts
6. Use Go to definition to jump to a module in node_modules
   module file is opened on the participant. On the host side, the app.module.ts file is closed and active editor becomes the previously edited file. If no files were edited previously host side has empty set of editors.

Expected behavior
module file is opened on participant and the same file is opened on the host side as well.

Describe the bug
Add support for syntax coloring for .vue files.

To Reproduce
Steps to reproduce the behavior:

Describe the bug
When using Save As in the browser, the results differ from what is expected on the host. The dirty changes should only show in the new file.

To Reproduce
Steps to reproduce the behavior:

1. Start a session and join as participant
2. Take control and edit a file (e.g. test.html)
3. Save the file under a different name via File > Save as (e.g. test1.html)

Expected behavior
Actual: original file (test.html) is saved with changes and new file (test1.html) is created without the changes

Describe the bug
As of now, we're not showing java proposals for constructors, only text proposals for them. Invoking content assist for the constructor part does not bring up any specific language proposals for it, only text proposals.

To Reproduce
Steps to reproduce the behavior:

1. In a Java file add "import java.io.*;"
2. In code try to create a new FileInputStream

Expected behavior
We should get content assist for constructors.

Is your feature request related to a problem? Please describe.
Working in multiple projects at once isn't supported.

Describe the solution you'd like
Currently, we start the session in the context of the current project. If a user opens another project in a new window, session stays active. So in result, it is active from both windows (including content of a Presence view) but actually only the first project is shared.

Describe your primary environment
IntelliJ developer.

Currently session participants are anonymous. We should allow participants to login or at least provide a visible name stored in a browser cookie.
