NumPy array metadata (shape, dtype, ndim)

Type: Feature Request

Hello VS Code team,

Feature request: please add an option to show NumPy array metadata (shape, dtype, ndim) directly in the Variables/Locals view when debugging Python. Current workarounds (Data Viewer, Watch, Debug Console) are helpful but a compact shape/dtype column would greatly speed up debugging numeric code.

Use case:

• Quickly inspect array shapes/dtypes (e.g., frame.shape, frame.dtype) while paused at breakpoints without opening the Data Viewer or adding watches.
• Helpful for image-processing / ML workflows where many arrays are inspected frequently.

Suggested design:

• Add optional compact badges or columns in Variables: name | type | shape | dtype | value-preview.
• Or provide a toggle Python: Show Array Shape/DType in Variables.

Repro steps:

1. Open a Python file using NumPy arrays.
2. Start debugger and pause on a line where arrays exist.
3. Observe Variables view — shape/dtype not visible by default.

Environment:

• VS Code version: 1.109.4
• Python extension: 2026.2.0
• OS: linux

Thanks for considering.

Regards,

Modes:

まず、TypeScript デバッガー拡張機能で Variables/Locals を描画するエントリーポイントを特定し、停止中の Python 値がどのように表現されているかを確認します。NumPy の shape、dtype、ndim をどこで公開できるか、またオプション表示がどのように動作すべきかを判断します。完了とは、Data Viewer や watches を必要とせず、停止中に要求されたメタデータが表示されることです。
