Hi,

Sorry for the confusion.  I did indeed mean that we'd aim to mimic the same functionality from within a simple PHP page which could be included as part of the RoundCube code.  In theory, RoundCube could easily support any of the 3 possibilities (PHP port, the Nox service in Python, or GoogleSpell) since all three use essentially the same output syntax.  All that is required is to change the URL/port to which the spelling code connects.  This could be a config option, with the default being Google (since it requires no additional software to be loaded on the server).

Moving forward, I have an implementation question.  From PHP, there are two ways we can talk to ASpell.  One is the same as the Nox server's approach which is to execute and process command line output.  The other is to use PHP's PSpell library.  As I understand it, there are two issues here: 1. The command line option can be restricted for (obvious) security restrictions.  2. PSpell library has to be enabled.

I want to choose the option that has the greatest chance of being acceptable to admins and the least burden for setting up...  Do most PHP environments allow command execution 'out-of-the-box'?  If not, my feeling is that for anyone to use ASpell they'll need to install ASpell anyway so enabling the library extension probably isn't an unreasonable expectation.  And we don't need to have a config parameter in RoundCube directly to deal with the path to ASpell's executable, which is another advantage.

Anyone have advice/thoughts on which is the preferrable route?

Thanks!

Andrew
