Instead of 'success dots' in the gutter, all commands seem to think there are fail exit status. Here are my dotfiles: and a branch to help debug: The debug branch just build an array of what commands were that triggered the trap and print them at the start and end of building the prompt. It does show the trap being called twice when shell integration is enabled - and once otherwise. The repro environment/steps: Repros in OSX and WSL Ubuntu 22.04 for me. It uses dotbot. In a scratch user directory you can run ./install to link everything into ~/. Pass to ./install to avoid installing extra tooling it finds missing (pygments/tmux/coreutils)There is a script that get's sourced . This is the root of all evil. It's on the hacky side. The function is small and is (I believe) the only relevant part. I should stop using it, but it's sooooo_ ingrained into my muscle memory. To verify: Removing from makes everything work great with none of the above mentioned problems. One hack, that seems irrelevant is that uses debug trap directly, but also detects and uses the pre-exec infrastructure if it has been loaded (to not break iTerm2's shell integration). I appreciate the time and effort going into this feature. It's becoming a shockingly advanced embedded shell environment.
thanks again, planning on tackling this in June
I use just merged in a fix for this. It would be great if someone could help verify in tomorrow's insiders build as I'm not normally a user of bash-preexec.
Still some problems around . Very simple repro: clean environment. My bash and vscode versions are: use this .bashrc: For me (In WSL, repros in plain OSX): ! Without ! If extdebug works, then this would be the next simplest test (I think). Same clean environment. The following

Type: <bBug</bWhen pressing to collapse all nodes in a list view it leaves selection in such a state that you cannot expand nodes with until you do something to change the selection. ! I believe what's happening is is leaving the originally selected node selected. So after executing the command you end up with 2 selections, your original selection plus the last root node in the list. The original selection is the primary selection, and if it has no children does not have anything to expand and is a no-op. As a user it looks like you have the root node selected, which has children to expand, but pressing does nothing. Pressing then expands the list to reveal your original selection and you see that you unexpectedly have multiple selections. The current behavior of appears to be: Leave the originally selected node selected Add a second selection to the last root node in the list The expected behavior here is: Move selection to the root node of your currently selected node Ideally this also retains multiple selection: each selection is moved to the root node of that selection.

Looking at this again in the File Explorer it looks like the selection highlight is left on the where the original selection was despite the fact that the node is now in a different position. However, the "real" selection is still on the node. This means it looks like one thing is highlighted and pressing opens a different thing.
Just submitted a PR for this. Could you please review it?
What is the behavior supposed to be? Here's what I see: keyboard to focus a tree node that has a parent to collapse all moves to the whole tree and arrow down takes me to the first tree element. Right arrow does nothing.
The current behavior sort-of fixes the issue, insofar as is dodges it by doing something less desirable - moves selection to the whole tree. Imo, selection should remain on the root node(s) of whichever tree branch selection is currently in.

I think this is what the previous behavior was trying to do, it just had an issue with leaving selection in a bad state. A couple examples ([x] denotes current selection): Start state End state, after Stat state End state

Testing Type in the settings editor. It would be nice if there was autocomplete for a list of languages. This is a finite list which we should be able to suggest fyi !
It's easier to discover language overrides in the editor because there is autocomplete there: !
Thanks to for pointing out the language service to me the other day. PR ready above.
/verified? The autocomplete works but no matter what I write there I get the same set of settings? I suppose all of these apply to all languages. ! !
Yep, the idea is for it to show all language-configurable settings. Then, the user can read and write settings for that language. I plan on making it so that the tab says which language you're on, for extra confirmation.

similar to the 'open in data viewer' command from the jupyter variables view, we should allow extensions to contribute a view for a variables for specific language/types on the built in tree view.
That would essentially be number 6 in this screenshot from the Julia extension , right?
Same idea, either with an icon like that or through the context menu on that item. In the jupyter extension's case, we are planning to allow contributions for data viewers from extensions that didn't necessarily provide the variables.
Cool. I think icon and context menu would be great ;) It might also make sense to think a bit ahead there: there are probably some kind of viewers that are relevant for a lot of languages (tabular data, plots) and others that are very language specific. From our end, we would love it if VS Code at some point gained a generic tabular viewer, and a plot viewer that we could utilize and get rid of our custom implementations as well :) So maybe some kind of API design where in the future one could hook into a as of yet not existing generic tabular/plot viewer.
Example implementation here The menu contribution point name will likely change names when we expand the usage beyond notebooks, but any needed migration will be pretty straight forward.
I created a sample extension and cannot see any variables showing up. Do I need to enable something in VS Code for this feature to work. I couldn't find any settings/experiments that had to be enabled for this.
Found that I needed to enable a VS Code experiment (I was looking for Jupyter experiments). Not sure the API is useful in its current form. Currently when i create a viewer for DataFrames, lists, objects, anything I do not get the name of the variable. Hence I have no idea what I'm looking at, all I get is a value, and thats basically a stringified version of the value. Thus its not really possible to create any viewer, unless of course I'm missing something here.
Moving to March for now. Feel free to move back to February if the issue has been verified or once steps are provided and the issue is verifiable in the latest Insiders. Edit: I confirmed using the sample extension that the viewer does not report the variable name.

verification: sure you have jupyter and python extensions enabled the notebook variable view the or create your own some notebook cells that create variables and open the debug sidebar to see the notebook variable view that the command contributed to the menu is provided information about the variable ( should be the expression that would access that variable)

Basically in the core webview module (see ), three default context menu actions (cut, copy and paste) are to the menu, which are accessible throughout all webviews, and happens to be one of them, so after you right-click anywhere in a image previewer, you will be able to see these three actions. After you clicks one of these actions, the editor will post an message to the image previewer, telling it to cut, copy or paste. If there is a correspondent listener for this perpose, the image will be actually cut, copied, pasted, but unfortunately there is no such listeners defined. This problem has existed for quite a bit of time. The original modification that cause this problem is from here . It is origianlly meant to allow users to copy selected text within an extension's README page. There is also a closed issue that describe such issue in . Personally I think providing action cut, copy and paste for all webviews is a little bit hasty, since there are not universally required for each webview, and even some of them need, the subject to be copied may vary from different webviews, or even different places in a same webview. I can solve it by disabling the default actions first (there is a option to achieve this), then let image previewer to implement its own copy and cut functionality, but I think this is rather a quick and sloppy solution. There should be another better way to solve this issue.
What about adding a handler :
Here's what I tried VSC insiders without any extensions Open a folder with a .png file Open the png file in vscode Right click and select Paste into folder in vscode = does not work Paste into markdown cell in vscode = does not work What am i doing wrong?
Pasting image data into folders isn't supported by VS Code. Pasting into a notebook cells works fine for me though. To verify though you can also paste into an external image editor

the extension host's event is only emitting from 's event, but the explorer is using the 's , which doesn't seem to talk to the working copy service. What do you think the fix here should be? (cc
the bulk edit service is using the for its operations. If you look at , there is a bunch of usages for that service. The working copy file service is a wrapper around the file service that ensures the relevant events are emitted and can be participated on. I suspect that for the copy/paste operation or drag/drop we are possibly not using the bulk edit service but the file service directly? I suggest to make a pass over all explorer code and look for raw usages of to replace with bulk edit service. I think that would even enable undo/redo properly.
My bad, the real bug is that this block: doesn't handle events. cc

open explorer select a file press and to copy paste a file in place :bug: nothing happens, in the past I would get a copy of the file
Hmmm. I cannot repro this and am able to copy and paste. Do you have any custom keybindings? What is your setting?
It's the default, this is from the keybindings log
Hmmm I wonder what has happening with your keybindings. Here's mine triggering the explorer specific ones with the proper when clauses. Is your explorer in a non-default position (i.e. not the activity bar)
This gets more and more interesting... The keybinding is there and not (re)configured but it looks like something is wrong with context keys. The seems AWOL. Maybe that's because I moved the explorer around very much last endgame? <img width="2819" alt="Screenshot 2023-03-01 at 16 55 16" src="https://user-"
Think I found the bug. the folders view to the right sidebar the remaining explorer view container in the activity bar Can't copy and past in the explorer anymore
I know this is very early into the next release cycle, but could this be released in a patch to stable VSCode? I have been bitten by this in stable VSCode after the February 2023 update, by dragging Explorer over to the secondary sidebar. Or is there a workaround to restore functioning of these keys, other than resetting the user profile altogether? I've tried dragging the Explorer menu back, and also right-clicking and selecting "Reset Location". Neither seems to "restore" the functionality of these keys. This affects any command using in , such as deleting a file with the Delete key (hopefully people find this issue instead of creating a new one for every such broken key). The workaround I've managed to apply is to manually remove from every expression possible, which may have side effects, but it works in a pinch. Copy all the keybindings below (expand for details, grab bindings between the comments) into your to fix this in a pinch. <details</summary</details
Does the command in the command palette not fix it for you? This will reset all your views to their default positions.
My keybindings workaround bypassed the issue on my home computer yesterday.

Now I'm at work (both are Windows machines, VSCode up to date), and I went to try your approach. However, I have a lot of menus in my secondary sidebar, so I didn't want to on my main profile, so I did the following: Ensure my workaround from before is commented out Export the profile as Import the profile Switch to that profile Verify that the key doesn't work First, try the less invasive, right-click on Explorer button in secondary sidebar and click key, and others, works again, even when putting the Explorer back in the secondary sidebar Curiously, switching back to the profile, the key, and others, works again, even when putting the Explorer back in the secondary sidebar Never had to go the nuclear option and So, some funny business related to one of the steps above, probably the settings profile shuffle, restored basic functionality of those keys, without having to manually tweak the expressions as before, and without having to go nuclear and . It's possible to work around this with some UI shuffling, but your mileage may vary. My initial request to backport the patch to stable VSCode is not so serious since there are a few workarounds documented here. Also, thanks for the quick work in the PR! I'm looking forward for this behavior to stabilize in future versions, since secondary sidebar Explorer view (without the compromise of moving the whole primary sidebar over) is great!

When you hover over a type in a TypeScript file, the tooltip that appears has a very low max width, making it difficult to read long type signatures.
I would include a screenshot but it's not easy to take a screenshot keeping the tooltip on screen!
! Errors are quite unreadable if the width does not adapt to the font size.
! it would be nice if the tip used the available space instead of wrapping at an arbitrary point in c# too
!
! Same problem using rust's language server.
General styling control would be very helpful. Also line-height. Another approach would be to have a bottom panel that displays the full error and the tooltip displays a shortened version.
!
! When using the auto import feature it is often impossible to differentiate whats what as the import path is cut off due to the limited width of the suggestions window.
Is this something we can adjust with custom css? It makes snippet infoormation very difficult to read as well. !
Same in Python. We have to jump through hoops trying to flow doc nicely. And when it appears OK on Windows, it breaks on Mac... ! And it is inconsistent. Ex, hover is OK ! But completion list decides to wrap. What gives? ! Looks like hover respects markdown while completion item doc is plain string and gets wrapped randomly.
!
Someone say long type signatures? !
Here is a workaround by hacking the file "C:Program FilesMicrosoft VS Coderesourcesappoutvsworkbench" Simply append the code above after the original content of file, and restart VSCode. (Title bar may alert a warning message "Not Supported" and hacked changes would be overridden by updating VSCode) !
It would be nice to have some control on the width. The above does work but vscode presents the message your installation may be corrupt on restarting.
Instead of hacking the CSS directly as mentioned above, I recommend using the to just override the current CSS. That way when VSCode updates, you can just reload the custom css file that you have specified (personally, I have a project where I hold configurations for my shell, Spacemacs, etc. and this custom CSS file goes there). Until it's officially supported, hacking the CSS is likely the best route.

The suggested widths above were a bit much for me, so I settled on the following values for now:
What is preventing the devs from providing a configuration option for this? This issue has been open for almost 2 years, and it bugs me on a daily basis. Would love to see it fixed.
(since you seem like the most relevant person to ping) is anything likely to be done about this?
I would love to hear an explanation from devs too. What are the difficulties of implementing this? I imagine it's settings a dynamic max-width and adding some more lines to add it in Settings. Are there other design blockers?
Will you take a look at this? In 3 days it will be a 2 year anniversary for this simple feature request.
Assigned to and as I remember we are going to have some UX improvements for editor tooltips and so on.
maybe now is the time to take this on? current iteration tries to solve parameter hints ux and this is not that much different
! I employed CSS and put together full instructions: [Custom CSS and JS Loader extension][1] macOS VS Code: VS Code Insiders: Linux: : [1]: Restart VSCode Ignore "VSCode is corrupt" error You can choose to suppress this notice forever Run command "Reload Custom CSS and JS"
just as a disclaimer, if anyone modifies the CSS/JS of the app, it comes up at “corrupted” in diagnostic checks, and you’ll typically get pushback if you report issues and include diagnostic information. Or, at least, I received pushback when I had custom CSS/JS enabled, and wouldn’t receive help until I turned it off (even though it was harmless/not related to the issue I was having). While this is indeed an okay workaround, we should just keep making our voices heard so that this is natively supported.
100% agree. This is just a workaround. It's hard enough to read TypeScript lint as it is! :)
Currenlty using VSCode 1.30.2, followed instructions step by step, but it's not working. I don't even get the VSCode corrupt error. I'm running Windows 10 (V.1803). Edit: It was my mistake. For anyone who's having trouble, make sure to run Enable Custom CSS and JS from the command palette. Simply restarting won't work.

This issue seems to be fixed in 1.32.0-insider (1.32.0-insider) . I hope this is an intended behavior. I want to thank the developers.
This change is related to . I confirmed that the max width of is still small as mentioned above. <img width="867" alt="2019-02-22 17 06 19" src="https://user-"
Update: in , only the hovers for problems and the hovers with code blocks become to have larger width. Others have smaller width.
Hello there,your solution is great,but I want to ask how to get rid of the word at the title.As sort of OCD,sufferring from that. thx a lot!
This extension was created specifically for solving this:
This has been a long standing annoyance, with an issue that's like 2 and a half year ago. It shouldn't take much effort to have a config property that overrides the width/height of the tooltip, surely? Like, 10 mins of effort? <img width="525" alt="Screen Shot 2019-07-18 at 6 41 15 PM" src="https://user-"
if it's really 10 mins of effort, then I'm sure you can submit a PR for this? I definitely can't do this in anywhere close to 10 mins, so it would be much appreciated!
Seriously, I want instead of this: ! At least something like this (with syntax highlighting it will be even better): !
There's already been a PR. I really don't understand this. I figure most VScode devs develop VScode in VScode, are they comfortable with the current state?
fyi, it would be great if the hover could be resized
How is this issue 4 years old and such a basic thing still isn't implemented?
Is there any word on whether we could see this soon? The suggestion widget has had resizing enabled since v1.51 in October, 2020. Is this tooltip widget considerably harder to add this feature for or are there additional considerations to be made? Whether it's a click to resize, or a manual adjustment in settings, could we have an update on the status of this addition? Opening new editor tabs just to properly read code annotations for some more descriptive components on my large monitors does feel like an unnecessary extra step.
