Debug strings are truncated #6496

HughGrovesArup · 2023-10-05T16:11:35Z

Type: Bug

Issue Description

Note that version 2.4.2 and before of the C# plugin does not display this behaviour.

Steps to Reproduce

Create a project with a string longer than 1000 chars
Enter debug mode and copy the string

Expected Behavior

Should be able to see full string length, or be able to configure this limit.

(We need to see the full length strings for our debugging purposes, string length has not bee an issue so far - even very long ones).

Actual Behavior

String cutoff with ellipsis

Thanks for reporting this @HughGrovesArup

Two notes:

The expected behavior is that the initial value displayed should be truncated (ex: in the window text, or if you hover over it). But, if you copy it to the clipboard using 'Copy Value', that should give you the full raw text. The fact that that is still truncated is definitely a bug.
While you are waiting on the fix, you can work around this for now by evaluating something like 'myBigString.Split(<insert a reasonable split here, like maybe \n>)orSystem.Linq.Enumerable.Range(0, (myBigStringVariable.Length 99)/100).Select(x => myBigStringVariable.Substring(x100, Math.Min(100, myBigStringVariable.Length-x100))).ToArray()` so that each string stays under the limit.

HughGrovesArup · 2023-10-06T07:49:02Z

Thanks for the response, good to know that this is not intended behaviour. We can stick with 2.4.2 for now as a workaround as well.

tisaconundrum2 · 2023-10-06T18:04:14Z

Glad to see other people are experiencing this issue as well! I thought I was going nuts

tisaconundrum2 · 2023-10-06T18:33:56Z

For those wondering how to use a specific version, go to dotnet/vscode-csharp/CONTRIBUTING.md for how to create a VSIX package to install into your VS Code. Release 2.3.27 does not seem to have this issue.

Just wanted to make a note here - you don't even have to build the vsix yourself - you can right click the extension in vscode and hit 'install another version' which will bring up a UI to revert back to an older version we published to the marketplace

gregg-miskelly · 2023-10-11T17:57:57Z

Fixed with #6517

gregg-miskelly · 2023-10-11T18:27:32Z

Full description of the new expected behavior (which will ship in the next version of the extension): Strings are truncated if they are longer than 1024 UTF-16 characters, but the full value up to 5,242,880 characters or 10 megabytes, is available using 'Copy Value' in the watch or variables window. Truncated strings will end with '...'.

namighajiyev · 2023-10-13T07:29:38Z

Copy value copies truncated value with ellipsis at the end.

C# : v2.6.24
Vs code insiders: 1.84.0-insider

gregg-miskelly · 2023-10-18T19:05:03Z

This shipped in v2.7.25, which is now live in the marketplace.

monster-echo · 2023-12-05T12:10:18Z

In the v2.12.19 on macos, it's still thuncated.

gregg-miskelly · 2023-12-05T17:10:04Z

@monster-echo the current behavior is that you will get a string truncated at 1024 characters unless you use 'Copy Value'. But I think your complaint makes sense that we should also use a larger truncation limit when evaluating from the Debug Console. I opened #6719 to track that.

monster-echo · 2023-12-06T12:28:46Z

I mistake the extension, this sence happened in the MAUI project .

This repository is still the vscode maui extension too? @gregg-miskelly

gregg-miskelly · 2023-12-06T17:29:22Z

@monster-echo MAUI issues should be opened in https://github.com/microsoft/vscode-dotnettools/issues

nomo-app · 2023-12-11T13:17:42Z

A similar bug also happens with Flutter/Dart-debugging (right-click -> copy value gives me an incomplete string).
My full string has a length of only 132 characters, but VSCode is unable to give me the full 132 characters.
Not sure where to open this issue.

gregg-miskelly · 2023-12-11T17:21:26Z

@nomo-app You would want to open that bug in the repo of whatever extension's debugger you are using (not here :)).

durandt · 2024-01-24T15:40:36Z

I also still get that issue with debug variables truncated after 100 characters (I use v2.15.30)

I also use C# DevKit and MAUI extensions

@gregg-miskelly how are we supposed to know what extension is responsible for which parts/behaviors of the UI?

gregg-miskelly · 2024-01-24T17:06:05Z

@durandt This issue is specific to CLR/CoreCLR. MAUI uses Mono on iPhone, so this issue wouldn't address that scenario. Your new issue is the appropriate home for Mono issues.

balazsmeszegeto · 2024-02-22T09:18:53Z

I don't use MAUI, only vscode-csharp v2.15.30, but copying string values are still truncated

gregg-miskelly · 2024-02-22T17:02:59Z

@balazsmeszegeto if you have a repo, please open a new issue including steps to reproduce the problem
