红宝石的正则表达式在单词之前用双引号引起来 [英] Regex in ruby to enclose word before : with double quotes

问题描述

我有一个要转换为json字符串的字符串

I have a string which I want to convert in json string

以下是json的格式

               title: {
                    position: "bottom",
                    text: "Share of Internet Population Growth"
                },
                legend: {
                    visible: false
                },
                chartArea: {
                    background: ""
                },
                seriesDefaults: {
                    type: "donut",
                    startAngle: 150
                }

要将其转换为JSON字符串，我需要将AnyKey:替换为"AnyKey":
我在读有关gsub的文章.什么是确切的正则表达式来替换这种字符串

To convert it toa JSON string i need to replace the AnyKey: with "AnyKey":
I was reading about gsub. What can be exact regex to replace this kind of string

预先感谢
