* client of online-judge-tools for Emacs.

  Causion: This project is only support atcoder now.

  I will adapt it to others, such as Topcoder, Codeforce and so on

  in the future. Pull-Request, Issue, providing information, or any other

  contribution is welcome!



* How to Use?

  You have to install online-judge-tools(~oj~) [[https://github.com/kmyk/online-judge-tools][here]].

  In addition, this package depends on [[https://github.com/rejeep/f.el][f.el]] and [[https://github.com/magnars/dash.el][dash.el]]

  Then, you have to add ~oj~ to your path, or set path to ~oj~ to ~online-judge-executable~.



  Then, in buffer where ~online-judge-mode~ is on, you can use some command below:

  - ~online-judge-login~

  - ~online-judge-download-test~

  - ~online-judge-run-test~

  - ~online-judge-submit~

  - ~online-judge-test&submit~

  - ~online-judge-toggle-error-range~

  - ~online-judge-update-error-range~



  Let's try on AtCoder, for example.

  1. Run ~online-judge-login~ to login host for submit.

     Select atcoder, and put username and password.

  2. Make directory ~/somewhere/atcoder/abc140/~ and make file ~a.cpp~

  3. Open ~a.cpp~ with ~find-file~.

  4. Run ~online-judge-mode~. The string ~atcoder/abc140/a~ is displayed on mode-line.

     Host, contest and problem id is automatically recognized from directory.

  5. Solve and compile it (~g++ a.cpp~).

  6. Run ~online-judge-run-test~. Result of test is displayed.

  7. Run ~online-judge-submit~ to submit the file. Confirmation is needed by default.

  8. If URL detection or other oj job failed, you can directly #+setupfile: URL

     by ~online-judge-set-url~.

** The Other Useful things

  - ~online-judge-test&submit~ can automatically submit the file when tests are all collect.

  - ~online-judge-mode~ become automatically on when list of strings ~online-judge-directories~ has ancestor of the file.
