TurboWarp extension guide
Turn text into lines.
Count lines, read one line, or copy every line into a Scratch list with three focused blocks.
Quick start
Load the extension
Text Lines writes directly to Scratch lists, so it must run without the extension sandbox.
Add to TurboWarp
In TurboWarp Desktop, open Extensions, choose Custom Extension, then load the downloaded file.
Allow list access
Enable Run extension without sandbox when TurboWarp asks for permission.
How it works
One input, three useful results
Text Lines separates the input wherever it finds a line ending, then uses the resulting lines in the block you choose.

Apple Banana Cherry

- A blank input is one empty line.
- A final line ending adds an empty last line.

Details
Line endings and list safety
Works across platforms
LF (\n), CRLF (\r\n), and CR (\r) are all treated as a single line ending.
List changes are immediate
The selected list is updated as soon as the command block runs, and list monitors refresh automatically.
Before running: copy any list contents you need to keep. The block replaces them.
