Monaco-Editor HoverProvider 获取单词鼠标悬停

Monaco-Editor HoverProvider get the word mouse hovers over

如何在 Monaco 编辑器中找到我悬停的词?

我想显示数组中保存的单词的特定值。因此,当用户将鼠标悬停在单词上时,我想将该单词与保存在我的数组中的单词进行比较,然后显示该单词的保存值。

我知道这两种方法:

model.getValue() // gets all the text stored in the model
model.getValueInRange({startLineNumber, startColumn, endLineNumber, endColumn}) // gets the value in Range, but I don't now the start and end column.

这是我的代码,我只需要方法 getValueInRange 的帮助:

 public variableHoverProvider = <monaco.languages.HoverProvider>{
    // this is for getting the values on hover over context variables and shortcuts
    provideHover: (model, position, token) => {
        if (model.getLineContent(position.lineNumber).trim() !== '') { // if only whitespace don't do anything
            let current = this.store[this.store.length - 1]; // just the place where I store my words and there values

            console.log(model.getValueInRange({
                startLineNumber: position.lineNumber,
                startColumn: 1, // this is the information I am missing
                endLineNumber: position.lineNumber,
                endColumn: 5  // this is the information I am missing
            }));

             // TODO: I have to find somehow the word the mouse is hovering over
            // let getMatchingContextVariableValue = current.contextVariables.map(ctxVariable=>{
            //     if(ctxVariable)
            // });

            let test = current.contextVariables[22].value;

            return {
                contents: [
                    { value: test }
                ],
            };
        }
    }
};

有没有人知道如何获取我悬停的文本?或者如何计算getvalueInRange方法中的startColumn和endColumn?

这是Monaco-Editor HoverProvider Playground

您不需要通过 model.getValueInRange you can simply use model.getWordAtPosition

HoverProvider 可以方便地用 modelposition 调用,所以没问题。

提供一个可以由 monaco playground 执行的最小示例:

monaco.languages.register({ id: 'mySpecialLanguage' });

monaco.languages.registerHoverProvider('mySpecialLanguage', {
    provideHover: function(model, position) { 
        // Log the current word in the console, you probably want to do something else here.
        console.log(model.getWordAtPosition(position));
    }
});

monaco.editor.create(document.getElementById("container"), {
    value: '\n\nHover over this text',
    language: 'mySpecialLanguage'
});

请注意,此 returns 一个 IWordAtPosition 对象具有三个属性:

endColumn: number

The column where the word ends.

startColumn: number

The column where the word starts.

word: string

The word.

因此,要在悬停位置获取字符串形式的单词,您需要访问 model.getWordAtPosition(position).word
