Error Message

In the VS Code extension, the same paste renders inline in full, making long pastes (error logs, stack traces, code) very hard to work with.

Preflight Checklist

  • I have searched existing requests and this feature hasn't been requested yet
  • This is a single feature request (not multiple features)

Problem Statement

In the terminal CLI, pasting large text collapses it into a neat pill/badge ([pasted_text_blah]), keeping the conversation readable.

In the VS Code extension, the same paste renders inline in full, making long pastes (error logs, stack traces, code) very hard to work with.

Proposed Solution

Request: Bring the same paste-collapsing behavior to the VS Code extension — collapse large pastes into a clickable pill that can be expanded on demand.

The terminal CLI already solved this elegantly. Would love to see parity in the VS Code UI.

TL;DR

Implementing a text collapsing feature in the VS Code extension, similar to the terminal CLI, is likely to solve the issue of large pastes being difficult to work with.

Guidance

  • Investigate the code responsible for rendering pasted text in the VS Code extension to identify where the collapsing behavior can be introduced.
  • Compare the rendering logic between the terminal CLI and the VS Code extension to understand the differences and adapt the collapsing feature.
  • Consider using a similar UI component or library in the VS Code extension that is used in the terminal CLI to achieve the pill/badge behavior.
  • Evaluate the threshold for when to collapse large pastes, ensuring it balances readability and usability.

Example

No specific code example can be provided without access to the existing codebase, but the solution likely involves modifying the rendering function to check the length of the pasted text and conditionally render it as a collapsible pill.

Notes

The implementation details may vary depending on the specific technologies and frameworks used in the VS Code extension and the terminal CLI. Ensuring accessibility and proper handling of edge cases (e.g., very short or very long texts) will be important.

Recommendation

Apply a workaround by implementing a custom text collapsing feature in the VS Code extension, as upgrading to a fixed version is not mentioned as an option in the issue. This approach allows for parity with the terminal CLI's behavior and improves usability.
