v1.16.1 – Bug Fix: Copy button on code blocks no longer adds a trailing newline

Bug Fix

The copy button on code blocks was adding a trailing newline to the copied content. When pasting commands into a terminal, this caused them to execute immediately (the newline acts as an Enter keypress), which could be unintended and even dangerous.

What was happening:

• Toast UI's syntax highlighter always appends a \n to the last line inside <code>
• The copy function extracted this newline along with the code
• Pasting into a terminal triggered execution instead of allowing review

What changed:

• Added .trimEnd() to the extracted code before copying
• Only trailing whitespace is stripped – leading indentation is preserved
• Copied code is now clean and safe to paste

Why this matters:

• Commands no longer auto-execute on paste
• Code snippets paste cleanly into editors
• Safe for documentation and tutorials where users copy-paste commands

Technical note: This was a one-line fix in ToastViewer.vue – the processCopyButtons() function now uses .trimEnd() on the extracted text.
