Ace编辑器，如何打开块选择，而不必按Alt [英] Ace editor, how to turn on block selection without having to press alt

问题描述

通常在ace编辑器中，如果你按住alt键，同时进行选择，它将以块形式选择它，我认为是块选择。

Normally in ace-editor, to if you hold down the alt key, while making a selection, it will select it in block form which i think is called block selection.

我如何做，使其在标准的块选择，按alt替换为正常选择。

How do i make it so that it is in block selection as standard, and pressing alt changes it to normal selection instead.

我认为它有事情与此

function onMouseDown(e) {
var ev = e.domEvent;
var alt = ev.altKey;
var shift = ev.shiftKey;
var ctrl = e.getAccelKey();
var button = e.getButton();

var editor = e.editor;
var selection = editor.selection;
var isMultiSelect = editor.inMultiSelectMode;
var pos = e.getDocumentPosition();
var cursor = selection.getCursor();
var inSelection = e.inSelection() || (selection.isEmpty() && isSamePoint(pos, cursor));


var mouseX = e.x, mouseY = e.y;
var onMouseSelection = function(e) {
    mouseX = e.clientX;
    mouseY = e.clientY;
};

var blockSelect = function() {
    var newCursor = editor.renderer.pixelToScreenCoordinates(mouseX, mouseY);
    var cursor = session.screenToDocumentPosition(newCursor.row, newCursor.column);

    if (isSamePoint(screenCursor, newCursor)
        && isSamePoint(cursor, selection.selectionLead))
        return;
    screenCursor = newCursor;

    editor.selection.moveCursorToPosition(cursor);
    editor.selection.clearSelection();
    editor.renderer.scrollCursorIntoView();

    editor.removeSelectionMarkers(rectSel);
    rectSel = selection.rectangularRangeBlock(screenCursor, screenAnchor);
    rectSel.forEach(editor.addSelectionMarker, editor);
    editor.updateSelectionMarkers();
};

这在我的第15479行和第15528行之间的ace.js中找到了，

which i found in ace.js between lines 15479 and 15528, and this;

 else if (alt && button == 0) {
    e.stop();

    if (isMultiSelect && !ctrl)
        selection.toSingleRange();
    else if (!isMultiSelect && ctrl)
        selection.addRange();

    var rectSel = [];
    if (shift) {
        screenAnchor = session.documentToScreenPosition(selection.lead);
        blockSelect();
    } else {
        selection.moveCursorToPosition(pos);
        selection.clearSelection();
    }

第15561行和第15567行

line 15561, and 15567

推荐答案

看起来很简单，只要更改此行...

It looks as simple as changing this line...

var alt = ev.altKey;

...

var alt = !ev.altKey;
