Hi, EyeSee is a model for charts. The rendering logic is meant to be orthogonal.

There is EyeSee that andre Hora ported and enhanced. And we should improve it.

preparing data for diagramms

by Norbert Hartl

Hi, is there a toolkit that helps to prepare data for diagramms and such. I mean accumulating in time series like day, week, ..., calculating average, sums,.. and scaling data. Something that just eases to typical stuff one needs to go from log data to visual representation. thanks in advance, Norbert

This instance has a URI space.

By subclassing the root from ZnAutoMatchedRestCall you can use a #pattern class method like #( 'users' '*") to match URIs like /users/12 (with 12 being the first variable).

I think Phillipe did a great job in implementing the routing for http handlers. As far as I know the whole routing code is not seaside dependent at all. It is just the way to enable it. Would probably useful to have a look there and try to phase out the seaside stuff and enable it to adapt to different things like zinc. What do you mean? Norbert

I use it in production and I can say it is really easy to work with. Combined with the zinc lib you can have REST-like services _with_ proper mime handling data.

Re: [Pharo-users] RESTful Pharo app (not Seaside)

by Sean P. DeNigris

Thanks for all the responses. I'm reminded how great our community is. Also, REST is working out beautifully as a simple cross-language communication channel since every language and even the command line can send/receive via http. Straight XMLRPC felt like it was in my way by comparison.
