Re: [Pharo-project] File Out html with Syntax Highlighting

by Lukas Renggli

Pier-Shout does Smalltalk syntax highlighting to HTML. It is used for example in book.seaside.st and on various Pier blogs. It could be adapted to be used for LaTeX too.

Re: [Pharo-project] File Out html with Syntax Highlighting

A syntax-highlighted HTML export would be greatly appreciated. IMHO, it should be available in the MC browser, giving one file per package. My primary interest is pre-release checking of code, in particular for anything I should not have said in comments. -----Original Message----- From: pharo-project-bounces(a)lists.gforge.inria.fr [mailto:pharo-project-bounces@lists.gforge.inria.fr] On Behalf Of Levente Uzonyi Sent: Wednesday, February 10, 2010 9:12 PM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] File Out html with Syntax Highlighting On Wed, 10 Feb 2010, Nathan Tuttle wrote: > I find it very useful when learning a language to see the code > accurately syntax highlighted on a web page when a snippet is shown.

In Squeak there's a "copy html" menu item in the context menu of StringHolder (available in Browser, Workspace, etc.) which copies the contents as html to the clipboard. If you just want a few code snippets with syntax highlight you can use this (the syntax highlight is provided by Shout). If you need something more complex, you can still use Shout to higlight your code (which will give you Text objects) and Text >> #printHtmlOn: to convert it to html. Note that both the "copy html" menu item and the Text to html conversion was removed from Pharo so you have to roll your own if you need it. Syntax highlighting can still be done with Shout.

[Pharo-project] Live Distributed Objets - Why not in Smalltalk ?

by CÃ©drick BÃ©ler

Hi people (crosspost pharo and research) While googling for live objects, ie. an API to query live objects coming from the outside world (trade stuffs, information, or whatever information coming from a sensor etc...), I think I just found what I was lokking for. At least something exists. I think this is different from Croquet or Spoon (I think live objets don't need to be in another image, they are just independant entities). On this page [1], you'll find video demonstrating live objects (2nd part of the first one is really cool, especially when they drop the coordinate of a plane in the window...or when they inspect live objets). 2nd video id about integration in office tools. On this same page, there are several publications at then end. [2] and [3] are wikipedia references. Were you aware of that ? Could we build a platform in Smalltalk (I don't really need it, but I find this would be really cool). I don't need such a platform, this was just a midnight googling session... but hey it's coool :) Quote from wikipedia (as you can see Smalltalk inspired them ;) : "Originally, the term was used to refer to the types of dynamic, interactive Web content that is not hosted on servers in data centers, but rather stored on the end-user's client computers, and internally powered by instances of reliable multicast protocols. The word live expressed the fact that the displayed information is dynamic, interactive, and represents current, fresh, live content that reflects recent updates made by the users (as opposed to static, read-only, and archival content that has been pre-assembled). The word distributed expressed the fact that the information is not hosted, stored at a server in a data center, but rather, it is replicated among the end-user computers, and updated in a peer-to-peer fashion through a stream of multicast messages that may be produced directly by the end-users consuming the content; a more comprehensive discussion of the live object concept in the context of Web development can be found in Krzysztof Ostrowski's Ph.D. dissertation[3]. The more general definition presented above has been first proposed in 2008, in a paper published at the ECOOP conference[8]. The extension of the term has been motivated by the need to model live objects as compositions of other objects; in this sense, the concept has been inspired by ***Smalltalk***, which pioneered the uniform perspective that everything is an object, and Jini, which pioneered the idea that services are objects. When applied to live distributed objects, the perspective dictates that their constituent parts, which includes instances of distributed multi-party protocols used internally to replicate state, should also be modeled as live distributed objects. The need for uniformity implies that the definition of a live distributed object must unify concepts such as live Web content, message streams, and instances of distributed multi-party protocols." -- CÃ©drick [1] http://liveobjects.cs.cornell.edu/ [2] http://en.wikipedia.org/wiki/Live_distributed_object [3] http://en.wikipedia.org/wiki/Distributed_data_flow
