Open an existing file instead of creating a new one when showing the problem

不太确定我有没有正确理解的你的问题。

你可以试试在VS Code里，点击File > Open Folder...， 然后选择目标文件夹（默认情况下所有题目会存储在$HOME/.leetcode/），这个时候你就可以在VS Code里看到所有文件了。

我觉得在点击show problem时先判断一下本地有没有文件再来决定打开本地文件（如果本地有）或者拉取题目（如果本地没有）这样好一点，因为这样可以看到之前的草稿或者提交的答案

@taoweicn This is a good suggestion.

@SkyLin0909 Do you mean to make the extension work as @taoweicn said?

[evan-lin9]

@jdneo yes

@jdneo Hi，请问这是一个 PR-welcomed 的 issue 么？

[jdneo]

@poppinlp All the issues are PR welcomed. Just remember to discuss the implementation in the issue before sending out the PR.

Thanks

@jdneo
Thanks. Nice!
I've looked into the code about this issue since it really bothers me.

This issue is caused by the params we passed into the show API of leetcode-cli which will generate a new source code file every time. And i haven't seen a param for existence checking in show API.

So here may be some plans:

A: We could genearte the file name by ourself and by which we could do the existence checking to determine whether to use the local code or get the remote template by show API from leetcode-cli.

This could solve this problem but we may meet some new problems too:

• generating file name by id and slug which should be compatible with the present
• mapping the file extension with language

B: We could use show API to generate source file in a temp path and by which we could get the file name. Then do the existence checking.

It's a little bit simple solution but may cost more time since we will always call the API.

So, what's your option about this? I prefer the plan A and i feel free for any ideas. :)

@poppinlp Plan A sounds good to me. Would you like to make a PR for it?

[poppinlp]

Of course. I'll send it this weekend. :)
