[craftzdog (Takuya Matsuyama)]

It’s easy. Create init.js liks so:

inkdrop.onEditorLoad((editor) => {
  const { cm } = editor

  function showRelativeLines(cm) {
    const lineNum = cm.getCursor().line + 1;
    if (cm.state.curLineNum === lineNum) {
      return;
    }
    cm.state.curLineNum = lineNum;
    cm.setOption('lineNumberFormatter', l => 
      l === lineNum ? lineNum : Math.abs(lineNum - l));
  }
  cm.on('cursorActivity', showRelativeLines)
})

Result:
