Make linewise copy/cut configurable

lishid · December 20, 2021, 1:24am

I would like to be able to disable this behavior, since in my use case, more people seems to accidentally hit Ctrl/Cmd+C and wipe their clipboard, just when they’re about to paste. Would be even better if this can be configurable for copy and cut individually, since the linewise cut can be sometimes useful.

              view.focus()
            }, 50)
          }
          
          
function copiedRange(state: EditorState) {
            let content = [], ranges: {from: number, to: number}[] = [], linewise = false
            for (let range of state.selection.ranges) if (!range.empty) {
              content.push(state.sliceDoc(range.from, range.to))
              ranges.push(range)
            }
            if (!content.length) {
              // Nothing selected, do a line-wise copy
              let upto = -1
              for (let {from} of state.selection.ranges) {
                let line = state.doc.lineAt(from)
                if (line.number > upto) {
                  content.push(line.text)
                  ranges.push({from: line.from, to: Math.min(state.doc.length, line.to + 1)})
                }
                upto = line.number
              }

Would a DOM event handler for "copy" that just returns true if the selection is empty cover this?

Hmm you are right, that would work. Thanks!
