Running Applets directly from Google Code

One thing I have always liked about Curl is the lack of an independent compile/link step. You can run Curl applets directly from source code just using the Curl RTE, which will compile and link the code dynamically as needed. This gives Curl the immediacy and flexibility of scripting languages like JavaScript while retaining the performance of a compiled language. It also means that you can run Curl applets directly from a source code repository with a web interface that can be configured to return the appropriate Curl applet MIME type (text/vnd.curl). Luckily for me, Google Code provides such a repository, so I am able to configure applets in my ZUZU libraries to be run directly from the repository.

Here is an example:



The above applet is located at the URL:

http://zuzu-curl.googlecode.com/svn/trunk/zuzu-curl/LIB/applets/example.curl

This example applet takes arguments in the "query" portion of the URL to set the title of the example and to load the initial contents of the example either from another file or from the query itself (as in this case). This allows me to use the same example applet to show different editable examples in my blog. The embedded example applet used in the training section of the Curl Developer's Site uses the same trick; for example, see here.

Look here for instructions on how to configure your Google Code repository to serve Curl applets. This trick may work on other Subversion-based code hosting services such as SourceForge, but I have not tried it.

UPDATE: Unfortunately, there does not seem to be any comparable support for Mercurial-based repositories. See Google Project Hosting issues 2815 and 2920.
