调研方向

首先阅读本 issue 中描述的 reactStringReplace API 和 replacer callback 行为,包括当前如何使用 offset 参数。确定递增索引或额外的 callback 参数是否能够保留现有工作流,然后记录这一决定,并验证重复替换会生成唯一的 React keys,且不会吞掉匹配项。

由索引模型根据 Issue 内容生成。

描述

Hello! First of all, thanks for the nicest replacer for react. )))

There's a thing. I want to use index parameter in replacer function as a key for react to be happy and render all my replaced texts. If I do two replaces at a time, say

const firstStepTexts = reactStringReplace(myText, regex1, (match, i) => <span key={`first_${i}`}>{match}</span>)
const second = reactStringReplace(firstStepTexts, regex2, (match, i) => <span key={`second_${i}`}>{match}</span>)

Then, for initial string in pattern of ${match_second_regex_1} ${match_first_regex} ${match_second_regex_2} replacer would set the same key for both second regex matches, and then react would blow up swallowing the second match span entirely.

What I did for now was embedding offset param from the new lib version, but that's not the real solution obviously.

What I could do right now is to call .reduce with running total index and not calling reactStringReplace on array, but that way I'm missing perfect lib api use-case. From the api point of lib, I could think of two possible things: 1) having second argument for replace function be running index, and not exact string match index; or 2) having another one argument with that index for replacer function.

First option would almost definitely break someone's workflow (https://xkcd.com/1172/), second one makes api clunky (arghhh, fourth parameter).

What's your opinion on this? I would be happy to help with code, but messing with api without your decision feels not a way to go.
