I want to save my leetcode solution at local disk. Furthermore, I even want to run test case at my machine.

File "/Users/tiantengfei/.vim/bundle/leetcode.vim/autoload/leetcode.py", line 233, in get_problems
problems.extend(_get_category_problems(c))
File "/Users/tiantengfei/.vim/bundle/leetcode.vim/autoload/leetcode.py", line 220, in _get_category_problems
'ac_rate': p['stat']['total_acs'] / p['stat']['total_submitted'],
ZeroDivisionError: division by zero
E858: Eval did not return a valid python object

Currently, the problem description along with the template code(based on the programming language configured) opens up in a single split. Due to this, when we run LeetCodeTest, and errors which leetcode api sends back does not match with the buffer line number. This causes trouble in debugging. It would be great if we could open the problem split in a separate split, and the code template in another split. Configuration options, if provided, to configure the split would be an added bonus.

Thanks,

Thanks for implementing this good plugin!
I'm using this under Ubuntu 18.04 and Neovim.

I was able to sign-in and see menus ad lists.
However, when I tried to open a problem, an error occurs saying

Error detected while processing function <SNR>137_HandleProblemListCR[51]..<SNR>137_ProblemIdFromNr:
line    6:
E117: Unknown function: trim

E15: Invalid expression: problem['slug']

I tried several problems but it happened all the time. I don't think it's a keyring thing.
What am I missing here?

about some default value, i recommend:

if !exists('g:leetcode_username')
  let g:leetcode_username = executable('git')?system('git config --global user.email'):expand('$HOST')
endif

and about 'g:leetcode_china', perhaps can use :language message or $LANG to determine default value?

it is just an advice. Thanks!

I tried to :LeetCodeTest for the first time, but an error occurred: error: interpret_expected_id.

I found that leetcode has changed its API: skygragon/leetcode-cli#187 (comment)

Now https://leetcode.com/problems/restore-ip-addresses/interpret_solution/
doesn't return interpret_expected_id anymore. Please see the link above.

Is this sometime fixable?

NVIM v0.3.8

reproduce procedure:

1. open question 1, two sum question.
2. submitting with blank function
3. got error below.

or

1. open question 1, two sum question.
2. submitting with return [0,1]
3. got error below.

But it shows no error with the right code.

The error is:

Today, I run sudo apt autoremove and I find this plugin can't run as usual.

browser_cookie3 fails to retrieve cookie of default profile for Chrome if there are multiple user profiles(on Darwin for me). however, browser_cookie3 does support specifying cookie path explicitly.

may be something like this:

let g:leetcode_browser='chrome'
let g:leetcode_cookie_path='path/to/profile/cookie.db'

or we can infer browser from cookie path, keeping one config entry

let g:leetcode_cookie_path='path/to/profile/cookie.db'

This problem has cropped up recently, when I use LeetcodeTest(see the below image), the preview window show Accepted state, but you can see the actual answer is different from expected answer. The LeetcodeSubmit command can display state correctly.

example

I tried the problem "String to Integer (atoi)" and I wanted to test a dummy code as below.

class Solution:
    def myAtoi(self, str: str) -> int:
        print('xx')
        return 0

LeetCode webpage is supposed to show:

Wrong answer
Your input  "42"
stdout        xx
Output       0
Expected   42

However, What I'm seeing in (neo)vim is just:

# Test Input
"42"

Is this right? What info is the plugin supposed to show? Is my setting wrong?

MACOS: 10.14.6
VIM:8.1 1-1700
leetcode.vim: up to date.
python: 3.7.4

When I open my submitted code. I get my Chinese comment wrong rendered.It's just like messy code. I have no idea about this. It's there anyone who handled this situation. Pls guide me how to fix it.

the answer is :
class Solution {
public:
vector twoSum(vector& nums, int target) {
for(int i = 0; i < nums.size()-1; i++) {
for(int j = i+1; j< nums.size(); j++) {
if(nums[i] + nums[j] == target) {
return {i, j};
}
}
}
return {};
}
};

but submit can be accepted.

When I use Rust to solve problems, the problem's file name will be a problem. For example, problem one's file name is two-sum.rs, but in rust, we use _ instead of -. So I need to manually modify the file name to two_sum.rs, and if I want to test or submit, I must revise it again...

Top 100 list is also usefull. I know the current version has have some list. Add another may be quick.

Login in leetcode.cn both firefox and chromium. Tried set g:leetcode_browser both firefox and chromium, always get the info Leetcode session cookie not found. Please login in browser. when try to signin.

Hi, thanks for your work. Is there any plan to add more tags to show for leetcode problems? Like vscode-leetcode does.

        _echoerr('cannot open ' + LC_BASE)
        return False

    return True

leetcode.vim Python script is too long, I rewrite for add top list and add more test case.Do you have plan to rewrite python?

Looking at my debug logs, I can see the response does not contain a judge_type to make the decision
See:
https://github.com/ianding1/leetcode.vim/blob/master/autoload/leetcode.py#L351

Instead, I noticed that submit and run code return two differently formatted submission_id values.

Opening pull request to fix this at least on my end.

Hi, thanks for your work.

I try this plugin, I is very good. But I just can login and browse problem, But can't test and submit. I try figure it out. The result is my email is not active.

VIM plugin was working from long time. Starting today 11/26/2019, leetcode plugin is not able to sign-in. Not sure if its due to some changes to leetcode APIs.
I tried changing the password and logging in using the new one. Didn't work.

Thanks for creating this!

Would it be possible to make the plugin focus on the window split when we interact with plugin? Right now any action I take, I have to press extra keystrokes to switch to the window split created by your awesome plugin.

I have installed the pynvim and the browser-cookie3. And ~/.local/bin was also added to PATH.
Then I installed this plugin. But when I execute LeetCodeSignIn. The following error occurred:

My browser is chromium, and there are my settings.

let g:leetcode_china = 1
let g:leetcode_browser = 'chrome'
let g:leetcode_solution_filetype = 'cpp'

Not sure if that is enough for a pr, so maybe just add rust to the list in the Readme? I tried, and it actually works fine. Thanks!

Hey, I wonder how to close test or submit buffer..
Or how to switch to these buffers.. Thanks..

While signing in I got the following error:

When running LeetCodeSubmit, I get a window with expected output.

When run command LeetCodeList in Vim got:

Hello, my vim shows "g:leetcode browser is disabled", how can I fix it?

I have already logged in my browser, but it still couldn't use it.
I think the options have been OK.
This is my settings:

let g:leetcode_china = 1
let g:leetcode_browser = 'chrome'

I can sigin in on mac , but have error on arch linux

Hi, @ianding1 . This is a helpful plugin. I think it should be better if support difficulty and status filter.

The company section is to long, and I don't need them if I don't subscribe the problems. I think is a good idea to provide an option the hide this section. The same problem with paid only problems. I don't need to see them in the problem list.

I can do this if you agree.

I'm new for playing leetcode with terminal. I'm also a vim lover. I find both this project and skygragon/leetcode-cli are popular. I don't know how to choose. Can you help me? Very Thanks.

I wanted to set my pset to 'top-interview-questions.' This was a little troublesome, so I wanted to show how to do it if anyone is ever curious. Also, I wanted to throw some suggestions out.

I had to inspect the endpoint requests in my browser because g:leetcode_problemset='top-interview-questions' was not working. It turns out that the endpoint is actually 'g:leetcode_problemset=favorite_lists/top-interview-questions'

It would be really helpful if the README and docs had a list of available options.

This alone didn't work, though, because of how the problem object is created. For some reason, the favorite_lists/top-interview-questions endpoint does not contain a reference to 'category.'

For a cheap workaround, I had to go into autoload/leetcode.py and comment out line 223:

#'category': content['category_slug'],

It would be helpful if we can add that key only for psets where we know it is necessary.

After signing in and running :LeetCodeList:

Error detected while processing function leetcode#ListProblems:
E119: Not enough arguments for function: printf
E15: Invalid expression: printf('leetcode.get_problems(["all"])')

and, from :help printf:

printf({fmt}, {expr1} ...)				*printf()*
		Return a String with {fmt}, where "%" items are replaced by

so that {expr1} seems to be required.

This is isolated and shown when running :echo printf("x"):

Hello!

Thanks for awesome plugin. It looks interesting.
I didn't find, is it possible to change input for LeetCodeTest command? It would be nice to change input for testing before submitting the solution.
