FAQ

  • I cannot install this tool on my Windows machine. How should I do?
    • Use Windows Subsystem for Linux (WSL). If your Windows is too and WSL is not supported, you can use virtual machines, MinGW or Cygwin, but you should buy a new machine.
  • Are there features to manage templates or snippets?
  • I usually make one directory per one contest (or, site). Is there a support for this style?
    • Yes. You can use --directory (-d) option. However, I recommend to make one directory per one problem.
  • Can I specify problems by their IDs or names, instead of URLs?
    • No. I have tried it once, but it is actually not so convenient and only increases the maintenance cost.
  • I don't want to give my password to this program.
    • You can use this giving only your session tokens. Please see here.

For other questions, use Gitter or other SNSs.
