MonacoEditor 主動觸發代碼提示功能

MonacoEditor是微軟提供的代碼編輯器瀏覽器

vscode便是使用它做爲編輯器。編輯器

它的開發語言是ts,能夠嵌入到瀏覽器中。ide

 

代碼提示或者說代碼補全功能是咱們常常須要定製的部分。this

目前它提供的快捷鍵是ctrl+space,和win10如下的操做系統的默認中英文切換是衝突的。spa

檢查源碼發現,TriggerSuggestAction的觸發快捷鍵已經寫死:操作系統

 

        function TriggerSuggestAction() {
            return _super.call(this, {
                id: 'editor.action.triggerSuggest',
                label: nls.localize(0, null),
                alias: 'Trigger Suggest',
                precondition: contextkey_1.ContextKeyExpr.and(editorCommon_1.EditorContextKeys.Writable, editorCommon_1.ModeContextKeys.hasCompletionItemProvider),
                kbOpts: {
                    kbExpr: editorCommon_1.EditorContextKeys.TextFocus,
                    primary: 2048 /* CtrlCmd */ | 10 /* Space */,
                    mac: { primary: 256 /* WinCtrl */ | 10 /* Space */ }
                }
            }) || this;
        }

 

既然無法改快捷鍵,它的run方法實現以下:prototype

        TriggerSuggestAction.prototype.run = function (accessor, editor) {
            SuggestController.get(editor).triggerSuggest();
        };

 

便是說,只要有辦法調用這個triggerSuggest便可,可是SuggestControll而是個私有對象,要如何調用呢?code

繼續看源碼:對象

        SuggestController.get = function (editor) {
            return editor.getContribution(SuggestController_1.ID);
        };
        SuggestController.prototype.getId = function () {
            return SuggestController_1.ID;
        };

    SuggestController.ID = 'editor.contrib.suggestController';
    SuggestController = SuggestController_1 

能夠得出結論blog

editor.getContribution('editor.contrib.suggestController').triggerSuggest

這個就是咱們所須要的調用代碼。

 

固然,還有一種更推薦的形式:

editor.trigger('隨便寫點兒啥', 'editor.action.triggerSuggest', {});
