Copy Selected Code With Line Numbers

VSCode extension that copies selected lines or ranges together with their line numbers. The copied content can be formatted either as plain text or as a Markdown fenced code block, making it easy to share precisely referenced snippets.

Features

• Copy every line that intersects the current selection (or cursor) with aligned line numbers.
• Copy only the selected text range with aligned line numbers.
• Toggle between plain text and Markdown output formats via the extension setting.
• Editor context menu entries and optional keyboard shortcuts for quick access.
• Localized status messages (English, Japanese, Simplified Chinese, Korean).

Commands
