# Vim plugin for CodeForces

## What allows to do

* Watch standings of contests ([Unofficial](http://i.imgur.com/yI5bhBs.png), [Friends](http://i.imgur.com/2o730zV.png), [Official](http://i.imgur.com/avSplri.png), [Room](http://i.imgur.com/nRH64jB.png))
* Submit source code (thanks to [CountZero](http://codeforces.ru/blog/entry/14786]))
* Watch result of last user's submissions ([Results](http://i.imgur.com/hDWFJXo.png))
* Load text of problems ([Russian](http://i.imgur.com/Q5M9fsd.png) | [English](http://i.imgur.com/NAmMBEj.png))
* Download last submission of user to problem ([qwerty787788's solution to F](http://i.imgur.com/vqvZV7Y.png))

## UPD (18.05.2016)

I have finally returned submit function to my plugin! You should _run_ server (`python2 ~/.vim/bundle/codeforces.vim/plugin/server.py`) in plugin folder before contest. It opens chrome(now hardcoded). To start contest and login execute `:CodeForcesInitServer`, but before it add new variable `g:CodeForcesPassword` and do not forget about username in your `.vimrc`. You can use this window to watch CF, but I'd recommend you to move this window on another desktop, it will be managed by server. After successful login, you can submit with `S-F5` as it was done before.

If you find a way to work with `PhantomJS`, pull request it! :)

New dependencies: python2-flask, python2-selenium

## UPD (02.10.2015)

You can use 'Cyan' in coloring of standings after revolution!

P.S.: Please, merge CountZero's submitter with my plugin, I wish my plugin should submit :)

P.P.S.: does anybody use this plugin?)

## UPD (28.05.2015)

After fixing bug of csrf-token contest list(with count of solved problems) and getting friends doesn't work. I wish I can fix it, but help me if you can. Also standings-with-friends can fail if you have many friends(cauze of get-request length restriction). Before contest I advice you to refresh _all_ data, related to _you_, some values can expire(except for user-agent, ofc) suddenly. Read about these variables below
I didn't test it in trains, but it shouldn't work in not public contests at all except for submit, but after update I'm not sure

## What I'm planning to do

* Full coloring of standings (I tested it on 10k users, it runs veryveryvery slow. So, I leave it as it is or, please, say how to do it in other way)
* <s>Room standings</s> Done
* Parsing samples and automatic testing like (C|J)Helper does. In progress...
* Deleting unused code, local includes (C++) (You can watch [here](https://github.com/Igorjan94/CF/blob/master/staff/importer.py), script, which 'links' your code in specific format)
* <s>Change `tabnew` to user-defined command</s> Done.
* ...

## Using and configuring

### Installation

* Use your favourite plugin manager, for example `Bundle 'Igorjan94/codeforces.vim'`, then `:PluginInstall`
* Just clone rep to your `.vim/` directory

All variables and functions have name with prefix 'CodeForces'

## Dependencies

* Python
  * requests   (all network)
  * HTMLparser (loadProblem, loadSubmission, loadFriends)
  * flask, selenium (submit)
* [EasyAlign](https://github.com/junegunn/vim-easy-align) for beautiful standings

### Variables

set count of users on one page to 40(default 30):

- `let g:CodeForcesCount = 40`

Get list of contests: (count of solved problems doesn't work!!!)

- ` :CodeForcesContestList `
- ` :CodeForcesContestListNext `

### Bindings

Of course, bind it like you want, I just suggest this:

- ` nmap <leader>cfr <ESC>:CodeForcesSet_R_ound `
- ` nmap <leader>cfS <ESC>:CodeForces_S_ubmission<CR>`
- ` nmap <leader>cfp <ESC>:CodeForces_P_revStandings<CR>`
- ` nmap <leader>cfn <ESC>:CodeForces_N_extStandings<CR>`
- ` nmap <leader>cfs <ESC>:CodeForces_S_tandings<CR>`
- ` nmap <leader>cff <ESC>:CodeForces_F_riendsSet<CR>`
- ` nmap <leader>cfu <ESC>:CodeForces_U_nofficial<CR>`
- ` nmap <leader>cfl <ESC>:CodeForces_L_oadTask `
- ` nmap <leader>cfP <ESC>:CodeForces_P_ageStandings `
- ` nmap <leader>cfR <ESC>:CodeForces_R_oomStandings<CR>`
- ` nmap <leader>cfA <ESC>:CodeForcesP_a_rseContest<CR>`
- ` nmap <leader>cft <ESC>:CodeForces_T_est<CR>`
- ` nmap <leader>cfcl <ESC>:CodeForces_C_ontest_L_ist<CR>`
- ` nmap <leader>cfcn <ESC>:CodeForces_C_ontestList_N_ext<CR>`
- ` nmap <leader>cfcp <ESC>:CodeForces_C_ontestList_P_rev<CR>`
- ` nmap <leader>cfF <ESC>:CodeForcesLoad_F_riends<CR>`

I think `<S-F5>` is very difficult to press occasionally, so:

- ` noremap <S-F5>  <ESC>:w<CR><ESC>:CodeForcesSubmit<CR>`
- ` noremap <S-F6>  <ESC>:w<CR><ESC>:CodeForcesUserSubmissions<CR>`

### Other

Folder CF:  
`codeforces.standings` -- file to store standings

`codeforces.users` -- file with colors. In next versions will be command-generated, now by hand. Let's color users how you want!
Format: `handle Color`

`codeforces.friends` -- file with friends. Simple list
`Color = { Red, Yellow, Purple, Blue, Green, Gray, Unrated }`

## Known <s>bugs</s> features

* It doesn't check any information entered by user
* Submission for teams doesn't work
* THEY MUST BE, I just haven't found'em
