It is also not very configurable without +changing the code. All of these problems will be remedied eventually. + + +Features: + +- Use Vim to edit your TopCoder Arena problems! +- Keeps track of code files locally and syncs with the server, so no more + copy and pasting to and from the Arena applet. +- Works with any language. +- Downloads and stores a copy of the problem statement with your code for + off-line viewing. +- Basic support for templates (currently C++ only). +- Local test-case drivers can be automatically created with the example + test-case data (currently C++ only, and has bugs). + + +Compatibility: + +I've tested the plug-in only on my own computer which runs x86_64 Linux. +It should work on other setups, but note the following: + +- The program "gvim" should be in your PATH. +- Vim needs to be compiled with client/server support. To check, make sure + the command "vim --version | grep +clientserver" prints something. +- The test-case driver generated for C++ uses POSIX functions for timing, + so it may not compile on non-POSIX systems (i.e. Windows). The C++Driver + template simply needs to be changed to support other timing functions. + + +How To Install: + +Assuming you have the downloaded the VimCoder jar file: + +- Run the TopCoder Arena applet. +- Click the "Options" menu and select "Editor" to show the editor + preferences. +- Click the "Add" button to bring up a new window. +- For "Name," type "Vim" or whatever you want to represent this plug-in. +- For "EntryPoint," type "com.dogcows.VimCoder" without the quotes. +- For "ClassPath," click on "Browse" and locate the VimCoder jar file. The + third field should now have the path to the jar file. +- Click "OK" to close the window with the three fields. +- Click "Save." + +You should now be able select "Vim" (or whatever you entered the first +field) to use the plug-in. If it doesn't work (i.e. nothing happens), you +may need to restart the applet or set the plug-in as the default editor. +Your mileage may vary. + + +Known Bugs: + +- Lack of documentation. The code itself is also poorly documented. +- Only C++ templates are provided. +- The generated C++ driver code won't compile when the method has one or + more parameters that are vectors (i.e. vectors of strings). +- The $CARAT$ token doesn't seem to work in the templates. +- Directory where code and problem data is saved is hardcoded at + ~/.vimcoder. This should be configurable. + diff --git a/src/com/dogcows/VimCoder.java b/src/com/dogcows/VimCoder.java new file mode 100644 index 0000000..489e789 --- /dev/null +++ b/src/com/dogcows/VimCoder.java @@ -0,0 +1,403 @@ + +package com.dogcows;
