A (hacky) tool to manage codeforces submissions.

Usage: cf-subm:
  list
  fetch [username]
  stalk [username] [num_problems]
  savetojson [username] [filename]
  code [username] [problemname] [filename]

• list lists the number of submissions stored for each user.
• fetch fetches all (accepted) submissions made by the user. If run again (after making additional submissions), it keeps adding submissions until finding one that it has already encountered.
• stalk displays the most recently solved problems by a user.
• savetojson exports the Submission struct's data for each submission for a particular user to a json file.
• code downloads an accepted submission's code.

// In russian time
class Time {
public:
  int month;
  int date;
  int year;

  int hours;
  int minutes;
};

struct Submission {
  std::string problem_name;
  std::string problem_letter;
  int submission_id;
  int contest_id;
  Time time;
};

Building on linux is simple enough. Make sure you have libcurl-dev installed. The steps for doing this vary in accordance with your Linux distribution. For example, for Ubuntu you would do:

sudo apt install libcurl4-openssl-dev

If this does not work for you, try googling 'how to install libcurl [your distribution]'.

CMake should work right off the bat. Simply do the following:

cmake -S . -B build
cd build
make

This is the tricky part. You will first need to install vcpkg, which is a C++ library manager. To do this, first make sure you have git installed (considering the fact that you're using GitHub, I'm gonna assume that you do). Then run these commands (taken from here) in a suitable directory (perhaps C:/):

git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
bootstrap-vcpkg.bat
vcpkg integrate install
vcpkg install curl:x64-windows-static

Next, you will need to add an environment variable to your system. This variable will store the path of where you've installed vcpkg. For example, if your root folder is in the C:/ directory, your path would be C:/vcpkg.

Press on the windows key and search for 'Edit the system environment variables', Click on 'Environment Variables...', and below 'System variables', click 'New...'. Type in your variable name as VCPKG_ROOT and your path as your respective vcpkg directory's path. Make sure to use forward slashes and not backward ones.

Once you're done with all this, you can finally compile the code using CMake. Do note that you will not be able to use MinGW (since libcurl is built with MSVC and not with MinGW. If you're up for it and can successfully build libcurl using MinGW, feel free to do so) and will have to use a Visual Studio kit in CMake. Here's the commands you'll need to run:

cmake -S. -Bbuild -T host=x64 -A x64
cmake --build build --config Release --target ALL_BUILD -j 10 --

Note: if the first command does not work, try replacing it with cmake -S. -Bbuild -G "Visual Studio 17 2022" -T host=x64 -A x64. You might need to change 2022 to 2019 or some other year depending on the version you have installed. Ignore this if the above commands work.
