A codeforces plugin for vim, ported from vim plugin gabrielsimoes/cfparser.vim.

Installation

• Install curl
• Install cfparser-pro with your favorite plugin manager. With vim-plug:

Plug 'sharifMinhazul/cfparser-pro'

Optional setup

You can setup some variables at your .vimrc:

• g:cf_cookies_file - File in which curl will store cookies (default: '~/.cf_cookies')
• g:cf_default_language - Language to be used when it it not recognized from file extension (default: g:cf_pl_gpp - g++). Languages are mapped in plugin/cfparser-pro
• g:cf_locale - Language to download problem statement. Either "ru" or "en" (default: "en")
• You can also redefine the function cfparser#CFTestAll(), that is, the function that is called to test your solution against test files. The default definition is as follows. You can redefine the function by writing your own version of it at your .vimrc, after loading cfparser-pro.

function! cfparser#CFTestAll() "{{{    
    let match = matchlist(expand('%:p'), s:cf_path_regexp)
    let input = expand('%:p:h'). '/'. match[2]

    if &mod
        execute 'w'
    endif
    if !filereadable(input.'0.in')
        call cfparser#CFDownloadTests()
    endif

    echo system(printf("g++ -Wall -std=c++14 %s -o /tmp/cfparser_exec;
                        \cnt=0;
                        \for i in `ls %s*.in | sed 's/\\.in$//'`; do
                        \   let cnt++;
                        \   echo \"\nTEST $cnt\";
                        \   /tmp/cfparser_exec < $i.in | diff -y - $i.out;
                        \done;
                        \rm /tmp/cfparser_exec",
        \ expand('%:p'), input))
endfunction

This will compile the file with g++ and test it against a0.in and a0.out, a1.in and a1.out, etc...

• You also redefine the function cfparser#CFRun(), the function that is called to test your solution in an interactive shell. You can redefine it by writing your own version of it at your .vimrc, after loading cfparser-pro. The default definition is below:

function! cfparser#CFRun() "{{{
    if &mod
        execute 'w'
    endif

    echo system(printf("g++ -Wall -std=c++14 %s -o /tmp/cfparser_exec", expand('%s:p')))
        execute '!'. '/tmp/cfparser_exec'
    call system("rm /tmp/cfparser_exec")
endfunction

This will compile the file with g++ and run it with the command warnings and std=c++14. You should change std=c++14 if you want other standard.

Usage

• <leader>cfi - Login (calls CFLogin())
• <leader>cfo - Logout (calls CFLogout())
• <leader>cfw - Who am I (calls CFWhoAmI())
• <leader>cfp - Display problem statement (calls CFProblemStatement())
• <leader>cfd - Download sample tests to current code folder (a0.in, a0.out, a1.in ...) (calls CFDownloadTests())
• <leader>cft - If tests are not downloaded then downloads tests and runs code with sample tests (calls CFTestAll())
• <leader>cfr - Runs code in an interactive shell (calls CFRun())
• <leader>cfs - Submit current open file (calls CFSubmit())
• <leader>cfl - List most recent submissions (calls CFLastSubmissions() without arguments - can be called with username as argument, default to logged in user)

Submit, download sample tests and problem statement functions "guess" the contest number, problem index and the programming language by the current file name in one of the following forms:

• directory/505/A/myfile.cpp
• directory/505/a.c
• directory/505a.c
