Isolate sentence

PopClip Extensions
1

despite being a bear of little brain with ADHD i have managed to make a couple of extensions all by myself and it is fun and good but now i am lost.

i asked mistral ai (a French chatbot that speaks perfect english) to help me make a popclip snippet which

ok not help. make it for me.
the purpose is to enable my brain to focus on a sentence and not get distracted by the other text on a page.

so it’s supposed to

  1. cut the selected sentence and put it on the clipboard.
  2. insert 20 empty lines where the sentence was
  3. paste the sentence into the middle of the space it created i.e. after the 10th line break
  4. insert the cursor at the end of the pasted sentence.

this is the dog’s breakfast it came up with :

// # popclip
// name: Isolate Sentence
// Icon: iconify:material-symbols:edit
// Description: Isolate the selected sentence with empty lines.
// language: javascript

function run(input, options) {
const app = Application.currentApplication();
app.includeStandardAdditions = true;

// Get the selected text (the sentence)
const sentence = input.text;

// Get the current selection range
const selection = app.selectedText();
const start = selection.range()[0];
const end = selection.range()[1];

// Cut the sentence to clipboard
app.setTheClipboardTo(sentence);

// Insert 20 empty lines
const emptyLines = Array(21).join('\n');
app.insert(emptyLines);

// Move cursor back to the start of the empty lines
app.setSelectedTextRange([start, start]);

// Paste the sentence
app.paste();

// Move cursor back to the original position
app.setSelectedTextRange([start + sentence.length, start + sentence.length]);

return sentence;

}

it installs ok but it doesn’t do anything. probably there is some obvious reason that a human eye would see straightaway, but not this one, and not the other one either.

any hints greatly appreciated!
