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

by Offray Vladimir Luna CÃ¡rdenas

Hi Manuel, This is really interesting! I like the idea of a graph and the way ILE manages metadata importation. Grafoscopio [1][2][3], is the software I'm creating for reproducible research and literate computing (mixing prose, code, queries, data and visualizations). It has alpha support for Zotero and I think that ILE and Grafoscopio could work together to provide researcher support for creating and working with research literature. [1] http://mutabit.com/grafoscopio/index.en.html [2] http://mutabit.com/repos.fossil/alvicoda/doc/tip/index.html [3] http://joss.theoj.org/papers/c92ed13fa746bc681081f9b31678841b Now my research workflow includes Pharo, TeXStudio, Grafoscopio, Zotero, Docear[4] and Hypothesis[5] to map and annotate research literature, but there is a lot of context switching, as you point in your presentation, and lack of moldability that we could get rid of, if those tools were integrated into Pharo. To manage this, I usually have two screens (see screenshot below) where I made annotated reading (in hypothesis) and map readings (in Docear). That is because Docear is not integrated (yet) with Hypothesis, which has a superb annotation system. [4] http://www.docear.org/ [5] https://web.hypothes.is/ I would like to have a similar tree like Docear reading interface , connected with the annotated reading of hypothesis (tags and comments), inside Pharo/Grafoscopio. In my ideal workflow I would add a bibliography item to Zotero (using add item by ID or dropping the URL/PDF), open it (getting the table of contents map inside Pharo, ala Docear and thanks to Hypothesis) and I would start to annotate and tag my readings. After that, some DSL would allow me to recover, visualize and export such annotations to be put inside of or connected with a Grafoscopio notebook and there I would finish the research writing. What do you think of this workflow? Could ILE support or be part of it in some way? Once you have packaged ILE, I could help as a tester in Gnu/Linux.

Each group directly retrieves information from selected classes. So there is no access to the full environment. I am working on the model refactoring. And it is one of the parts which I want to improve. I want method group to be based on query for methods and query for subgroups. So it will be straightforward to get what you want. Now you can implement it in global way like: YourMethodGroup>>methods cursor := ClySystemNavigationEnvironment queryCurrentImageFor: (ClyClassReferences of: classes). ^cursor retrieveAllActualObjects But to make it usable you should always show this group: YourMethodGroupProvider>>buildGroupItemsOn: items items add: (YourMethodGroup classes: classes) asEnvironmentItem because by default provider adds only not empty groups where empty check can lead to long computation > Cheers, > Juraj > > On Nov 2, 2017, at 12:23, Denis Kudriashov <dionisiydk(a)gmail.com> wrote: > > Hi > > There is no real documentation for now.

by Juraj Kubelka

Thanks! It works. Then I have two more questions: 1. How it is done that âshould be implementedâ has red color? 2. Then letâs say I want a message group that display all messages in the environment that refers to a selected class. I found `ClyClassReferences to: classes`, but I miss how to use it in that case. My class ClyClassReferencesMethodGroup should use it in #includesMethod: and #methods. What is the right way to use ClyClassReferences or access environment to make the query?

Hi There is no real documentation for now.

Extending Calypso

by Juraj Kubelka

Hi, Are there any examples (documentation) how to extend Calipso? I have tried to create a simple (demo) method group, but I miss something, because it is not called. I have created three subclasses of: ClyMethodGroup (with #name and #includesMethod:), ClySingleMethodGroupProvider (with #methodGroupClass), and ClyEnvironmentPlugin (with #collectMethodGroupProvidersFor:). What do I miss? Letâs say that I want a new method group that displays all methods of a selected class that include substring âfooâ. Thanks! Juraj
