Hard to answer. But linux knows where its libs are, at least when you do `/sbin/ldconfig -p` in CLI. Pharo should probably use this info somehow, question is, is there a kernel API to get to this, or is there another sane way to get to it? Of course, accepting 'libfoo' when asking for 'foo', but that probably is there already (I hope). And of course, honouring LD_LIBRARY_PATH, as it _is_ set in the pharo start script, so maybe even used, but... I am sorry I don't know how shared lib resolving works on linux. I am just the "as far as I can tell, the whole point of shared libraries is to ask OS for them and get them handed over" kind of person here. Ppl love Smalltalk so much, they forgive lots of rough edges - I think we should not be that forgiving (like, garbled utf-8 names read from git in iceberg-metacello integration; and there are lots of details like this, the issue in this thread being one of more serious ones of them. IMO).

Yes, all of this should work and we need to improve on this. I am willing to do something about that because it frustrates me too. Herby, How would you see it working?

Reading a text file line by line

by Dirk Olmes

Hi, I'm trying to get started with Pharo doing something really simple - at least that's what I thought ... I'm trying to read a text file line by line. If I use File named: '/tmp/linex.txt' readStream nextLine I'll get a debugger telling me that BinaryFileStream does not understand nextLine. Now I've tried my best to find a stream that may be reading plain text lines but to no avail ... Help! -dirk

Even for live state which is what the image excels you can use several micro formats like fuel , ston or other files of your own definition. Code wise I am relying on git. To build a new image I use a makefile, together with pharo startup script. https://github.com/kilon/makePharo The make file does the downloading of the vm and the image to the lastest version and also the deletion of a previous installation The startup script (regular smalltalk source file) it triggers only when the image is opened the first time and it dowloads my project. The project is available also via Package Browser, it acts as an umbrella that dowload all my projects and their dependencies using metacello and git. I only save images ONLY in case I wanto to store the live state which means almost never. Code is handlied only through git and github. I use an external git client called Gitup (Mac only). I dont use Pharolauncher or Iceberg. I was planning once to replace makefile with my own gui for getting and installing latest vm and image but I never tried it because I was happy with the makefile. > I'm assuming that the current state of the art is Iceberg; where can I > find a "This is how you should organize your project using Iceberg" > document, blog, book, tutorial, video, or otherwise. > > Once the application is done, I assume I'll want to ship it in a minimal > Pharo image.

But yes you could do it. I am not aware of a GUI tool that will do this for you , you will have to do this using code. Hacking the VM sounds too extreme for me, you dont need to, you could run a forked process inside Pharo and use UFFI to detect key presses without touching the VM. Of course this si necessary only if Pharo still does not have an API for global shortcuts. UFFI can do some pretty insane stuff, but be warned that most of them are platform specific which is both a blessing and a curse. UFFI basically gives access to C libraries which means the OS libraries as well so you can manipulate anything. You even make it capture shortcuts outside Pharo, for example when your application is meant to be run on the background, with minimised or no pharo window. Thanks! > > -Steven > > > >

For issue fixing I nearly always download a new image and recreate the situation in that. > Once the application is done, I assume I'll want to ship it in a minimal > Pharo image. Is there documentation or prior art on this? That is right, and you'd be early in doing that :) Basically just look at how the full Pharo image is built from the minimal image. Stephan

Re: [Pharo-users] How to make pharo find sqlite?

by Renaud de Villemeur

Hi I managed to get Sqlite work with Pharo under linux (Fedora), in both 32 and 64 bit. The setup has nothing to do with LD_LIBRARY_PATH. I'll use those example under fedora linux. First, of course, you need to install either UDBCSqlite or Garage-Sqlite drivers You first need to have sqlite3 libs installed on your system $ rpm -qa | grep sqlite sqlite-3.20.1-1.fc26.x86_64 sqlite-libs-3.20.1-1.fc26.x86_64 => for 64 bits version sqlite-3.20.1-1.fc26.i686 sqlite-libs-3.20.1-1.fc26.i686 => for 32 bits version Then find the path of your library $ rpm -ql sqlite-libs.i686 /usr/lib/libsqlite3.so.0 -> this is your path in 32 bits /usr/lib/libsqlite3.so.0.8.6 /usr/share/doc/sqlite-libs /usr/share/doc/sqlite-libs/README.md gnome@rdv:~ $ rpm -ql sqlite-libs.x86_64 /usr/lib64/libsqlite3.so.0 -> this is your path in 64 bits /usr/lib64/libsqlite3.so.0.8.6 /usr/share/doc/sqlite-libs /usr/share/doc/sqlite-libs/README.md Under Linux, you have to give the library path inside Pharo Image, or link the library from pharo VM folder: 1. Update library path from pharo image Using UDBDSQLite, update to return the path of the library on your system UDBCSQLite3Library >> library Smalltalk os isMacOS ifTrue: [ ^ #sqlite3 ]. ^ 'sqlite3' to UDBCSQLite3Library >> library Smalltalk os isMacOS ifTrue: [ ^ #sqlite3 ]. ^ *'/usr/lib/libsqlite3.so.0'* If you are using Garage,Update: GASqlite3FFI >> *library* *^ '/usr/lib/libsqlite3.so.0'* 2. link the library from VM folder: *ln -s /usr/lib/libsqlite3.so.0 libsqlite3 or *ln -s /usr/lib64/libsqlite3.so.0 sqlite3 if the module name is sqlite3 in your library method. Then your test should pass green. The reason it pass under windows is because the method library return by default sqlite3, which is the dll name you put under pharo VM directory to get it work. On linux, unless you link your library in the VM folder, the image has no clue where to find sqlite3. Hope this helps.

I had situation where the system libcairo:i386 does not work with Dr.Geo[1], Pharo crashes with what looks like a Cairo crash! Looks like not a Pharo fault, but I am definitely stuck. It is problematic, it is a system (LinuxMint based) used in Geneva primary schools and Dr. Geo was expected to be used there :( Hilaire [1] http://forum.world.st/Cairo-related-crash-with-Dr-Geo-tt4952023.html Le 01/10/2017 Ã 19:50, Igor Stasenko a Ã©critÂ : > > All these difficulties are good argument to get the appropriate > libcairo/libpng shipped with the Linux VM, as done with Windows > and MacOSX VM > > Nah, in my case, there's nothing that can be lableled as "Pharo > fault".

Organisation and workflows

by Steven R. Baker

Heya folks, [Please jump on any of my statements that sound crazy: use of Spec, other assumptions, etc.] I'm starting an application in Pharo, using Spec. Basically, a GTD application in the spirit of nirvanahq, omnifocus, things, nozbe. The code is working just fine, but I'm left with a lot of questions about how to organize it. First, is there some trick to managing images? Are people using one-per-project, or one-per-computer? All of the above? Anyone using PharoLauncher these days? Other tools? I'm assuming that the current state of the art is Iceberg; where can I find a "This is how you should organize your project using Iceberg" document, blog, book, tutorial, video, or otherwise. Once the application is done, I assume I'll want to ship it in a minimal Pharo image. Is there documentation or prior art on this? Finally, is there a way to run and capture keybindings globally? I have one part of my application (a quick-entry window) which I want summoned from a global (OS-wide) hotkey. Has this been done before? Or is it not easy to break the fourth wall, so to speak, and register a global keybinding from inside the VM? Thanks! -Steven

Roassal is working Ok on my Wndows 10 laptop now. But on my 32-bit Windows 7 PC at work it still does not work. Here's the steps to reproduce: ) Download whole Pharo 6.1 Windows package from http://files.pharo.org/platform/Pharo6.1-win.zip 2) Unzip it and open it by running Pharo.exe (not the .image file) 3) Load Roassal using following code: Gofer it smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; configurationOf: 'Roassal2'; loadStable. 4) Roassal now loads successfully. Go to Roassl example. Display examples. Everything works OK. No problems at all with Roassal. 5) Save imafge as "MyRoassal.image" 6) quit Pharo 7) Launch pharo again 8) select "MyRoassal .image" 9) Pharo opens the image but Roassal no longer works. It cannot find an external module. Somehow saving and re-opening the image has broken Roassal.

Took me a while for example to understand that, when using the snap version of Pharo, Python3 scripts called from Pharo would be unable to import libraries such as numpy.
