Re: Personal wiki / information manager

by sean＠clipperadams.com

[TheProjectProject](https://github.com/seandenigris/The-Project-Project) is the GTD component of [my Dynabook project](https://github.com/seandenigris/Dynabook). Behind it is about 20 years of work incorporating ideas from countless productivity disciplines - GTD, Steven Covey, Landmark Educationâs Mission Control spin off, etcâ¦ Motivation: * Even âgoodâ GTD apps miss the fundamental thing that virtually \*all\* apps miss - stovepiping a sliver of oneâs mental model into an app is already a losing proposition. Every significant object needs to be able to relate to every other one - financial transactions to personal projects to contacts in oneâs address book, to sources in oneâs library. * Personal productivity is a highly personal endeavor, so no off the shelf closed box software can ever really scratch the itch. Basing it on a live, dynamic, turtles-all-the-way-down system like Pharo is a must Disclaimer: even after 20 years, Iâm still not clear on some things, so it is actively developed and even the core ideas are still evolving as I continuously drive it via real world usage. Everything is MIT and Iâm happy to discuss and answer any questions. It is currently based on GToolkit (itself based on Pharo). Thereâs no reason the core model couldnât run on plain Pharo without GT, but itâs been a long time (several years) since Iâve put any love into Morphic UI components. HTH, Sean

Re: It's been a while since I've used Pharo, and I'm having trouble with multibyte input on linux.

by peter yoo

Due to personal circumstances, testing has been delayed. sorry. The environment is the same as before. 1. in SDL2 testime(SDL2 sample program). can see Korean input. (fcitx-sdl) 2. you can see SDL_IM_MODULE="fcitx" in the environment variable. AAA@BBB:~$ export | grep fcitx declare -x GTK_IM_MODULE="fcitx" declare -x QT5_IM_MODULE="fcitx" declare -x QT_IM_MODULE="fcitx" declare -x SDL_IM_MODULE="fcitx" declare -x XMODIFIERS="@im=fcitx" 3. my environment is xorg-x11 and gnome 3.(ubuntu 22.04) 4. of course, xterm can use XIM(fcitx) input. tested already. 5. I ran pharo11 from a separate command line, just in case it might be an issue with AAA /home/AAA/Pharo/vms/110-x64/lib/pharo "/home/AAA/Pharo/images/Pharo 11.0 - 64bit (stable)/Pharo 11.0 - 64bit (stable).image" I'm still not getting input using fcitx. I don't think it's going to be a one-time fix. How can I test it? Any suggestions on how to test or trace it would be very helpful.

Mapping global grassroots innovation: a data story powered by Pharo/GT

by Offray Vladimir Luna CÃ¡rdenas

Hi all, I wold like to share with you my latest data story, powered by Pharo/GT and is related with how to make global grassroots innovation information more available, particularly in places with low/intermittent connectivity. This practical use case of the Pharo ecosystems illustrates the joy of using it in: * Migrations from WordPress to TiddlyWiki. * Data scrapping, manipulation and versioning. * Data storytelling publication and exchanging. * Grassroots innovation to map grassroots innovation (we love meta systems ;-)) Here is the screenshot of the portable wiki: And here is the link to the GIG portable Wiki <https://mutabit.com/repos.fossil/gig/uv/wiki/>, so you can explore/play it by your self. Here is a screenshot of the data story explaining the behind scenes (motivations, future work, code, etc) of such prototype: And here is the link to the GIG portable wiki data story <https://mutabit.com/repos.fossil/gig/doc/trunk/wiki/en/gig-portable-wiki--1…> so you may enjoy the details as much as your nerdy soul needs ;-). Comments and feedback is welcomed here or as the way indicated in the data story. Thanks, as usual, for the technologies and the community behind, that makes such (data) stories possible. Offray

Re: Video in Pharo

by Esteban Lorenzano

what is the xid? The x11 thingy? in that case you will need to implement a method on GdkWindow (not GtkWindow): https://docs.gtk.org/gdk3-x11/method.X11Window.get_xid.html then you do something like: GRunLoop defer: [ xid := myGtkWindow gdkWindow xid ]. but this is tied to the x11 system and linux is going out really fast of it (is being replaced by Wayland). I can bet there has to be a better way to connect it to a window.

Re: Video in Pharo

by Jupiter Jones

Hi StÃ©phane, Thanks for your reply. Iâve been looking at GStreamer and itâs definitely another viable option. Do you know of any docs or examples of using it in Pharo. I tried a really simple test but get an error I donât understand just yet. ï¿¼ Iâll put some time into FFI (and gstreamer) so I can ask more appropriate questions. In any case, it looks like to link GStreamer with Gtk Iâll also need the xid :) So itâs back to working out how to achieve that.

Re: Video in Pharo

Hi Estiban, Thanks for that - works beautifully :) The next challenge was to let VLC know the xid for the gtk window, but of course the one function that answers the xid for gtk appears to be in yet another library (gtk-x11) which, of course, has no binding for Pharo as yet :) As Iâm new to FFI (as is my offsider), this will take a bit of learning and fumbling, so if someone knows itâs going to be a fools errand (ie. this isnât likely to resolve the link between VLC and gtk) please let me know. Otherwise, weâll dive in.

PharoLauncher is a great idea, and for Windows is a mustbut in linux world it just does not matches the philosophy: There are many distrubutions and changes and is impossible to correctly distribute a VM with all dependencies without using the packaging they expect (we need to start thinking on distribute the VM as a flatpak, but that will take time to be implemented). > You need to use the VM we provide with Open Build Service: https://software.opensuse.org//download.html?project=devel:languages:pharo:… > 3) finally, this is not a real problem immediately, but a recommendation: Pharo has different ways of being ejecuted. The default one will execute the VM and everything needed in the main thread. This is usually suitable for Pharo needs, but it is a problem when the UI loop is required to run separately (not just for Gtk but any backend that you need to run on idle mode). > Fortunaltely, Pharo implements also a way to be executed in a worker thread, making space so the main thread can be used for other purposes. We highly recommend that you execute Pharo using a worker thread (future versions of Spec-Gtk will require this usage, and is definitively better. > How to execute in worker thread: > pharo --worker MyImage.image --interactive > > I updated the README on pharo-spec/Spec-Gtk to precise this points. > > Cheers! > Esteban > On Jul 10 2023, at 7:17 am, Jupiter Jones <jupiter.jones(a)mail.com> wrote: > Another step forward. > > I created a new ubuntu 22 install, installed pharo 11 and installed spec-gtk. The first issue was the libraries are named: libgobject-2.0.so.0 and libpango-1.0.so.0 with the â.0â suffix.
