Any static web site generators for pharo with bootstrap support?

by Offray Vladimir Luna CÃ¡rdenas

Hi all, I'm planning to make a web site. Nothing fancy, just a web site for the grafoscopio project I have told you about already. I started to use Nikola blog engine[1], but, after a while I thought I want to try something else, something that can create static web sites like Nikola, but with more interactive feedback and made in Smalltalk. I have found Bootstrap for Seaside [2], but I don't want the "Seaside" part in the sense that I don't want to create any behaviour served by Seaside or configure any server for that matter, just to put some Smalltalk code that produces static html powered by boostrap and put it under distributed source control management, like I do now with my blog. There is something like that in Pharo/Smalltalk or any approach you suggest me to make it happen fluidly?

Please compile a list as you go :) Peoples first impressions good & bad are useful, and its the sort of comparison that is hard to think back to later on. good luck, cheers -ben

And there is FormCanvas>>#warpImage:transform:at:sourceRect:cellSize: this one works with a MatrixTransform2x3 (this may support scaling for x and y). 2015-02-21 0:40 GMT+01:00 Nicolai Hess <nicolaihess(a)web.de>: > 2015-02-20 23:56 GMT+01:00 Sean P.
