Re: [Pharo-users] LiteratureResearcher - where graphs, PDFs, and BibTex happily live together

by Manuel Leuenberger

Hi Bernardo, Thanks for the Xanadu hint. Indeed I made similar observations as Ted Nelson: We use desktop machines to replicate physical paper on the screen, blatantly ignoring that we can easily break the constraints of paper on a computer. This reminds a bit of Roy Fieldings thesis about REST, where he clearly defined what REST is. Yet, most implementations tagging themselves with REST are just RPC. People seem to look at technological concepts, take out all the good parts, only keep the name and claims, yet doing something different, but still marketing it as innovative and modern.

Hi renaud thanks for the feedback. Settings is way to describe settings. Now once you have a settings and save it you can take the setting code and wrap it into a startUpLoader actions. So there are really complementary. Ok I did not know that we change the class name. I will check because my preferences seems to work in pharo 70. Can you do pull requests for your suggestions so that the chapter gets improved.

Re: [Pharo-users] New Pharo Booklet

Toc, list of figures are managed by the latex template. So yes you have them if you template use it. In fact a template is just a latex with {{{title}}}, {{{attribution}}} We are working with guille in making pillar simpler to change. Students were not really well supervised by damien and they produce rather difficiult to understand and extend design so I'm slowly going over the points. Usually we can do the following - first level, renewcommand in latex so like that we do not have to extend the syntax of pillar - second level, we can use the option of a command such as ${cite:}$ I should check because for example we should be able to specify the bib file but we should extend the nodes and model of pillar. - third level we change the syntax but I would like to avoid it. What I can try is to convert one of your document and check how it goes. Now I'm really busy. How do they do it in pandoc? In pillar now you can embed plain latex using {{{}}} I guess but it means that you cannot export that nicely to HTML. I want to find a good css to produce a lot sexier output.

Re: [Pharo-users] LiteratureResearcher - where graphs, PDFs, and BibTex happily live together

by Manuel Leuenberger

Hi Dimitris, I looked around for a way to integrate PDF into Pharo. But as long as we donât have a way to natively display interactive multimedia (maybe Bloc will at some point support something like this?), I consider it not worth the effort to come up with a half-baked (note to self: watch that movie again) solution that is hard to implement and cannot even remotely support all the use cases as an external tool that have been crafted for years. Just rendering bitmaps loses so much information (full text) and actionability (hyperlinks). If I wanted to have interactive PDFs inside Pharo, I had to invest so much time to replicate functionality that has been implemented before. So, I chose the path of the least resistance by pushing this responsibility to a specialized tool. I think Pharo is great for modelling, exploration, and inspection, but OS integration is not really a selling point, and it doesnât have to be. By using a standard PDF viewer I also gain that users are already familiar with them and have their own workflow that I can extend. As a side note, I think that being able to embed a web browser inside Pharo would open up a whole new world of applications, as web browsers are currently the vehicles for content distribution. But as long as there is no project where this is a critical feature, I can live without it.

Re: [Pharo-users] Writing "powerpoint" like presentations in Pharo?

by Stephane Ducasse

I did that (well argh more than 12 years ago) now I do not think that I can find the code I will try It looks like I loaded in Pharo some years ago. Here the latest code I found (At that time I developed test first). I'm not sure that I will have the time to get a look.

Re: [Pharo-users] Permancy of booklet links

by Offray Vladimir Luna CÃ¡rdenas

In the case of Grafoscopio Manual, the URL is fixed [1] and the manual advices to use a unique identifier (version + revision) that appears in the front page and in the low corner of each page to report issues [2]. [1] http://mutabit.com/repos.fossil/grafoscopio/doc/tip/Docs/En/Books/Manual/ma… [2] http://mutabit.com/repos.fossil/grafoscopio/ticket Maybe this approach could be followed by other publications. We have done it for the Spanish Data Driven Journalism Handbook [3] [3] http://mutabit.com/repos.fossil/mapeda/ Cheers, Offray On 01/11/17 21:24, Ben Coman wrote: > > This link turned up in a google search on...
