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

Super cool more detailed recommendations when I try it on practice A cheap pdf viewer in Pharo would be to turn pdf pages to JPG images which you can load via image morph so you wonât have to have two separate windows. There are ton of converters out there that can do this.

LiteratureResearcher - where graphs, PDFs, and BibTex happily live together

by Manuel Leuenberger

Hi everyone, I was experimenting in the last few weeks with my take on literature research. For me, the corpus of scientific papers form an interconnected graph, not those plain lists and tables we keep in our bibliographies. So, here is the first prototype that has Google Scholar integration for search, can fetch PDFs from IEEE and ACM, extracts metadata from PDFs - all this results in hyperlinked PDFs! See a demo here: https://youtu.be/EcK3Pt_WnEw <https://youtu.be/EcK3Pt_WnEw> Also slides from the SCG seminar here: http://scg.unibe.ch/download/softwarecomposition/2017-10-31-Leuenberger-ILE… <http://scg.unibe.ch/download/softwarecomposition/2017-10-31-Leuenberger-ILE…> I plan on packaging it, so that those who are interested can check it out themselves (help wanted!). Currently, it only works on macOS. What do you think of my approach? Which use cases should be added? Cheers, Manuel

Pillar supports embedding LaTex and HTML inside your pillar files so whatever works for those should work for Pillar. Pillar also has templates you can modify via moustache. Pillar is actually so flexible I used as a static website generator utilizing moustache and bootstrap and worked like a charm. Itâs syntax is just the tip of the iceberg.

Oh there is also the possibility this is already available via GTInspector, last time I checked I remember it having a slideshow preview of images collection and it embeds a workspace as well. So maybe you already have what you need. On Wed, 1 Nov 2017 at 22:57, Dimitris Chloupis <kilon.alios(a)gmail.com> wrote: > Well technically this is easy to do with Morphic. Probably Spec 2.

Well technically this is easy to do with Morphic. Probably Spec 2. Doing it from inside the Pharo window will give you the ability to demonstrate live code and Morphic is live code. If you donât want to do everything with Morphic you can create this in any app of your choosing , export to images and have Morphic load those images. I donât see why this would take more than a couple of hours to prepare , the actual Morphic code should not take more than 20 minutes. It a simple case of a SystemWindowMorph embedding a couple of button morph (for going forward and backward) and an ImageMorph. Plus a timer if you want the slides to proceed automatically. If you feel adventurous you can do this entirely on Morphic , again should not take you more than two hours total together with content creation. TextMorph should be more than enough. I would have said use Pillar but in this case itâs an overkill and Pillar does not allow for the precise positioning of images like Morphic does.

For example from command line: pandoc --toc --latex-engine=xelatex --listings -H macros.tex BioSmalltalk.md -s -o BioSmalltalk.pdf I don't know if "toc" is supported in Pillar.

Writing "powerpoint" like presentations in Pharo?

by Tim Mackinnon

Hi - has anyone made anything where you can create a full screen presentation in Pharo with slides with some large text, bullet points and embedded pictures - but then itâs a facade that lets you evaluate items in the slide or jump to any code mentioned? Sort of like what Alan Kay does in the eToys images? I need to do a presentation next week and I always loved it when I was fooled into thinking I was looking at a staticâish powerpoint and then suddenly realised it was a live environment. It doesnât sound that hard to do something simple - but Iâm not sure if I can pull it off in time for my presentation. But am curious if we have something. (For bonus points, GT-Spotter stuff would work in it over top of the presentation to demonstrate simple things) Tim
