Detailed Description
Opa is a unified programming language designed to build rich Web applications in an agile and secure way. This package allows one to compile Opa programs into self-contained executable binaries. It is provided under the terms of the Affero-GPL licence v3.
Extended documentation on the language Opa is available on the project page, including a feature tour, a reference manual and the programming APIs.
Benefit to Fedora
This package makes the Opa platform easily available to Fedora users.
Scope
The package is almost ready for shipping. Our next steps can be listed as follows:
- submit a first package candidate of Opa for testing and validation (bugzilla ticket filled)
- find a Fedora sponsor
- possibly fix packaging bugs
- choose and submit a stable package for Fedora 17 among the versions 0.9.x of Opa.
How To Test
We carry extensive testing on the compiler every night and additional functional tests to prepare stable releases. Our testing platform is not available (yet) in opensource. Yet, building the library and compiling example programs from the documentation should provide a good testing coverage.
User Experience
The Opa compiler is available as a standard command-line tool. Emacs and vim mode are included in the package. We currently seek community support for our Eclipse plugin.
Users should appreciate the ability to create and run web applications in a few lines of code. See for instance our Hello world:
Server.start(Server.http, { page: function() { <h1> Hello </h1> }, title: "Hello" })
to be compiled with opa --parser js-like hello.opa, then run by ./hello.exe -p 8080.
