Re: [Pharo-users] Styling a Pharo UI application

by Dimitris Chloupis

In my case is just personal preference none the less Spec has ways to wrap morphs to Spec widgets so you should be able to build Spec widgets using Morphic for more flexibility. You dont have to decide to use Spec or Morphic, you can use both. Last time I checked Spec came with examples on how to do this and I think Spec docs also mention this. Also I think Athens is very good at rendering text (because its wraps around the Cairo library) , so maybe you can take advantage of that though I suspect Bloc may be even better choice in this case because it is based on Athens and it is fully compatible with Morphic. There is also a text widget that is being build that is much more flexible with handling text https://vimeo.com/67752734 Be advised though that both Bloc and TxText are far from finished On Fri, Jun 24, 2016 at 1:28 AM Tommaso Dal Sasso < tommaso.dalsasso(a)gmail.com> wrote: > Personally I don't dislike the Spec approach, but the API still looks not > expressive enough for doing things beyond the standard. > > I am deepening my knowledge of Morphic now, thanks for your answer! > Tommaso > > > > On 22/06/16 17:11, Dimitris Chloupis wrote: > > Documentation is always a problem. > > I dont use Spec because I dont like it , but I use Morphic for my project > ChronosManager.

Re: [Pharo-users] Pharo crashing under new Fedora 24 (64bits plus 32bits libraries)

by Renaud de Villemeur

Hi. Pharo5 can run properly on Fedora 24, with Seaside3.2, OpenGL, or default image. What kind of graphic card do you have ? Is it a NVidia ? The default driver in Fedora, "Nouveau", is 64 bit only. I had to install the proprietary NVidia driver lib in 32 bit to be able to run pharo, They are still from fedora 23, as rpm-fusion didn't update its repo yet (xorg-x11-drv-nvidia-cuda-358.16-2.fc23.i686 and xorg-x11-drv-nvidia-libs-358.16-2.fc23.i686). Here is a list of all 32 bits library I have. My system is not a fresh install, but Pharo is the only 32 bit apps, so I guess this list is quite accurate. Can you check if you have a similar list on your system ? $ rpm -qa | grep i686 | grep -v devel | sort -u alsa-lib-1.1.1-1.fc24.i686 bzip2-libs-1.0.6-20.fc24.i686 cairo-1.14.6-1.fc24.i686 clang-libs-3.8.0-1.fc24.i686 elfutils-libelf-0.166-2.fc24.i686 expat-2.1.1-2.fc24.i686 fontconfig-2.11.94-6.fc24.i686 freetype-2.6.3-2.fc24.i686 gamin-0.1.10-22.fc24.i686 glib2-2.48.1-1.fc24.i686 glibc-2.23.1-8.fc24.i686 keyutils-libs-1.5.9-8.fc24.i686 krb5-libs-1.14.1-6.fc24.i686 libcom_err-1.42.13-4.fc24.i686 libdrm-2.4.68-1.fc24.i686 libedit-3.1-14.20150325cvs.fc24.i686 libffi-3.1-9.fc24.i686 libgcc-6.1.1-2.fc24.i686 libICE-1.0.9-5.fc24.i686 libpciaccess-0.13.4-3.fc24.i686 libpng-1.6.23-1.fc24.i686 libselinux-2.5-3.fc24.i686 libsepol-2.5-3.fc24.i686 libSM-1.2.2-4.fc24.i686 libssh2-1.7.0-5.fc24.i686 libstdc++-6.1.1-2.fc24.i686 libuuid-2.28-3.fc24.i686 libvdpau-1.1.1-3.fc24.i686 libverto-0.2.6-6.fc24.i686 libwayland-client-1.10.0-1.fc24.i686 libwayland-server-1.10.0-1.fc24.i686 libX11-1.6.3-3.fc24.i686 libXau-1.0.8-6.fc24.i686 libxcb-1.11.1-2.fc24.i686 libXdamage-1.1.4-8.fc24.i686 libXext-1.3.3-4.fc24.i686 libXfixes-5.0.2-2.fc24.i686 libXrender-0.9.9-3.fc24.i686 libxshmfence-1.2-3.fc24.i686 libXxf86vm-1.1.4-3.fc24.i686 llvm-libs-3.8.0-1.fc24.i686 mesa-libEGL-11.2.2-2.20160614.fc24.i686 mesa-libgbm-11.2.2-2.20160614.fc24.i686 mesa-libGL-11.2.2-2.20160614.fc24.i686 mesa-libglapi-11.2.2-2.20160614.fc24.i686 mesa-libOpenCL-11.2.2-2.20160614.fc24.i686 ncurses-libs-6.0-5.20160116.fc24.i686 nss-softokn-freebl-3.24.0-1.0.fc24.i686 ocl-icd-2.2.8-3.git20151217.0122332.fc24.i686 opencl-utils-1-2.svn16.fc24.i686 openssl-libs-1.0.2h-1.fc24.i686 pcre-8.39-2.fc24.i686 pixman-0.34.0-2.fc24.i686 pkgconfig-0.29-2.fc24.i686 pyzy-0.1.0-12.fc24.i686 readline-6.3-8.fc24.i686 SDL2-2.0.4-4.fc24.i686 sqlite-libs-3.11.0-3.fc24.i686 xorg-x11-drv-nvidia-cuda-358.16-2.fc23.i686 xorg-x11-drv-nvidia-libs-358.16-2.fc23.i686 xz-libs-5.2.2-2.fc24.i686 zlib-1.2.8-10.fc24.i686 and for display: $ ldd vm-display-X11 linux-gate.so.1 (0xf778f000) libpthread.so.0 => /lib/libpthread.so.0 (0xf7729000) libGL.so.1 => /usr/lib/nvidia/libGL.so.1 (0xf7622000) libX11.so.6 => /lib/libX11.so.6 (0xf74e1000) libc.so.6 => /lib/libc.so.6 (0xf7313000) /lib/ld-linux.so.2 (0x565d0000) libnvidia-tls.so.358.16 => /usr/lib/nvidia/tls/libnvidia-tls.so.358.16 (0xf730d000) libnvidia-glcore.so.358.16 => /usr/lib/nvidia/libnvidia-glcore.so.358.16 (0xf50b8000) libXext.so.6 => /lib/libXext.so.6 (0xf50a4000) libdl.so.2 => /lib/libdl.so.2 (0xf509f000) libxcb.so.1 => /lib/libxcb.so.1 (0xf5079000) libm.so.6 => /lib/libm.so.6 (0xf5022000) libXau.so.6 => /lib/libXau.so.6 (0xf501e000) Beware that under Fedora, SSL in Pharo is not available.
