bespin
by Avi Bryant 19 Feb '09

19 Feb '09

Has anyone checked out Bespin? http://labs.mozilla.com/projects/bespin/ It's a web-based IDE, with a few interesting properties: - it's implemented from scratch on top of the <canvas> tag, which means it has much greater control (via javascript) over its appearance and behavior than most web-based editors - it uses a simple RESTful API to list, load, and save files and preferences from the backend. There's already a few alternative backend implementations (python, standalone Java, and Eclipse-based). - it has an extensible emacs-like command line to navigate or operate on the buffer The way it's laid out isn't ideal for Smalltalk code (fullscreen column browser navigation or fullscreen editor, not both in one window) but presumably that could be modified pretty easily. Probably wouldn't be too hard to throw together a quick proof of concept backend that exposed Smalltalk source to this... Avi

Multiple file uploads
by Louis LaBrunda 19 Feb '09

19 Feb '09

Hi, As part of a new Seaside project I expect to have a page where between five and ten files will need to be uploaded. The first thought is to have a fileUpload and callback for each file and expect that the files will be uploaded one at a time after a submit button is clicked. I am wondering if there is a way to have the first fileUpload start and upload (maybe with some Ajax function) while the next file to be uploaded is being named. Any ideas are welcome.

Porting
by Gerardo Richarte 19 Feb '09

19 Feb '09

What's required to port seaside to a new Smalltalk dialect? I mean, in terms of webserver (I know about continuations). Does it requires a webserver writen in Smalltalk? or I can use an external webserver and with FastCGI route request to Smalltalk? (I know this is GemStone's approach, but I'm wondering how much of a webserver you need to serve FastCGI, for example) I also know that Seaside can be plugged to a number of different Smalltalk web servers, what's this list? thanks! richie

But...will continuation-based coding be available as well?

preliminary questions..
by sergio_101 19 Feb '09

19 Feb '09

hi, all.. for awhile, i was reading along with the tutorial, and trying to actually DO it all, but it seemed like i was spending more time fiddling, and not understanding.. so i just read the tutorial like a book, and everything made WAY more sense. i am thinking about using seaside on a project i am starting in house, but i have a few reservations that i am hoping everyone will shatter for me.. a little background: we run a small development team.. 3 designers and a programmer (me).. we currently use rails. we have done several rails projects, and have kinda fallen into a groove... we use git to keep each other (and our testing server) in sync. we use capistrano to shove everything to the servers. we use mysql. the good part is, we are not married to any of these platforms.. but the upcoming project DOES have to have a mysql backend as another client will need to access the data. most likely directly. the project is a web app. we started doing web sites in rails, and have found that our projects are beginning to be more and more like apps. this new project is an app. here are some of the concerns i have: after reading about GLORP, it seems like it's alot of work to get up and running. if that is all there is, i can deal with that. what happens in the case where the database structure changes? when fields are added, changed, deleted, etc? it is really no big deal with rails and migrations, but how much work is this with glorp? team working - one of the designers on our team also does some of the programming work (displaying data, etc). how tough is it to keep a team like this together with monticello? i would like to be able just automagically suck in all changes in programming and design whenever they happen, without having to think too much about it.. deploying - we use capistrano to push everything out to a testing server and a production server. this also restarts the servers, etc. this is WAY easy.. effortless.. what is it like to deploy an application? workaday things - it seems that with rails, a LOT of the things you have to do for every project (authentication, scaffolding, crud, etc) are readily available via plugins. before i start to write anything that remotely sounds like something someone else might use, a quick search usually reveals something ready to install that someone else did.. okay, so if everything is so great, why do am i looking at other frameworks? a few things: while ruby is a great and fun OO language, rails still looks at the web as a series of pages. for a great number of applications, this is a totally workable scenario. once things start getting a little more intense, this approach totally gets in the way of itself. the seaside way is much more what i am looking for. the debugger in smalltalk is awesome. the debugging and development workflow are good enough that i am not even worried that i can't use emacs to develop. in rails, i am still using alot of really silly old school debugging methods. if persistence via an external database weren't an issue.. the agility of just banging out objects everywhere for everything seems WAY more speedy than developing while trying to make everything talk nicely to each other. anyway.... i would really value any input i can get.. thanks! -- ___ peace, sergio www.village-buzz.com photographer, journalist, visionary

copy #WATextInputTag>>size: to #WAFileUploadTag
by Louis LaBrunda 18 Feb '09

18 Feb '09

Hi, I respectfully suggest that #WATextInputTag>>size: size: aNumber "This attribute tells the user agent the initial width of the widget. The width is given in number of characters." self attributes at: 'size' put: aNumber be copied to #WAFileUploadTag. I am playing with the VA Smalltalk V8 Beta1 that includes Seaside. I have extended #WAFileUploadTag to include the #size: method and will suggest that Instantiations add it but think it would be nice if it were added to all Seaside platforms.

Comet and CTHandler>>basicTerminate
by Lautaro Fernández 18 Feb '09

18 Feb '09

Hello, I was wondering why each time a CTHandler is created the method basicTerminate is called. I tried digging into some messages but without success. Could someone (maybe Lukas) explain to me why does it need to do the following lines(*) when a cometRequest is "delivered"? (*)CTHandler>>basicTerminate thisContext swapSender: nil. Processor activeProcess terminate Thanks! Lautaro Fernández. -- Luke LAut SkyFernadezWalker
