Suponho que você esteja falando sobre a versão 0.2 do este plug-in
Se isso estiver correto, você realmente se incomodou em verificar o conteúdo do arquivo tc_emacs-0.2.tar.gz oferecido para download? Além do arquivo .jar, ele contém um README que contém claramente as instruções de instalação:
Install gnuserv. You can download it from http://meltin.net/hacks/emacs/ or just use a package if your GNU/Linux distribution provides one. The gnuserv must be working before launching the Arena. The easiest way is to put
(gnuserv-start)
in your .emacs file. The gnuserv will then be started together with Emacs.
Make sure that you have Emacs/W3 Browser installed in Emacs. You can check it by typing 'M-x w3 '.
Put topcoder.el and TCEmacs.jar in some directory. The topcoder.el file should be loaded before using Emacs in the Arena. You can do that by typing 'M-x load-library /path/to/topcoder.el ' or you can just place
(load-library "/path/to/topcoder.el")
or, to load the file only when it is needed:
(autoload 'topcoder-set-problem "/path/to/topcoder.el")
in your .emacs file. I had some problems with autoloading, though. The keymap in the TopCoder mode did not sometimes work and I had to reload topcoder.el manually.
Make a work directory and set the topcoder-directory variable to its name. By default it points to a directory named topcoder in your home directory.
Launch the Arena applet and choose Options/Editor/Add. Type in a name (e.g. Emacs), TCEmacs as the entry point and a path to the TCEmacs.jar file in the ClassPath field.
Now choose a problem to solve. If everything went fine, you should see two new Emacs windows, one with a problem statement and the second one with a source code template.
