使用正则表达式消除谷歌应用程序脚本中的换行符 [英] Eliminate newlines in google app script using regex

问题描述

我正在尝试为 Google Docs 编写附加组件的一部分，该附加组件使用 replaceText 消除所选文本中的换行符.明显的 text.replaceText(" ",""); 给出了错误 Invalid argument: searchPattern.我用 text.replaceText(" ",""); 得到同样的错误.以下尝试无效: text.replaceText("/ /","");, text.replaceText("/ /","");.我不知道为什么 Google App Script 不允许识别正则表达式中的换行符.

I'm trying to write part of an add-on for Google Docs that eliminates newlines within selected text using replaceText. The obvious text.replaceText(" ",""); gives the error Invalid argument: searchPattern. I get the same error with text.replaceText(" ","");. The following attempts do nothing: text.replaceText("/ /","");, text.replaceText("/ /","");. I don't know why Google App Script does not allow for the recognition of newlines in regex.

我知道已经有一个附加组件可以执行此操作，但我想将此功能合并到我的附加组件中.

I am aware that there is an add-on that does this already, but I want to incorporate this function into my add-on.

即使是基本的也会出现这个错误

This error occurs even with the basic

DocumentApp.getActiveDocument().getBody().textReplace("
","");

我的全部功能:

function removeLineBreaks() {

var selection = DocumentApp.getActiveDocument().getSelection();
if (selection) {
    var elements = selection.getRangeElements();
    for (var i = 0; i < elements.length; i++) {
        var element = elements[i];

        // Only deal with text elements

        if (element.getElement().editAsText) {
            var text = element.getElement().editAsText();

            if (element.isPartial()) {
                text.replaceText("
","");
            }

            // Deal with fully selected text
            else {
                text.replaceText("
","");
            }
        }
    }
}

// No text selected
else {
    DocumentApp.getUi().alert('No text selected. Please select some text and try again.');
}

}

推荐答案

似乎在 replaceText 中，要删除使用 Shift-ENTER<输入的软回车，你可以使用 v:

It seems that in replaceText, to remove soft returns entered with Shift-ENTER, you can use v:

.replaceText("\v+", "")

如果您想删除所有其他"控制字符(C0、DEL 和 C1 控制代码)，您可以使用

If you want to remove all "other" control characters (C0, DEL and C1 control codes), you may use

.replaceText("\p{Cc}+", "")

请注意，v 模式是 JavaScript 正则表达式引擎支持的一种结构，被认为匹配一个 垂直制表符 (≡ 13) 由大多数 Google 产品中使用的 RE2 正则表达式库提供.

Note that the v pattern is a construct supported by JavaScript regex engine, and is considered to match a vertical tab character (≡ 13) by the RE2 regex library used in most Google products.
