Package Browser 4

by Hans Schueren

Thank you for the information : Yes , the File with the extension .st is in the Pharo directory. First i couldn't find it by supposing a .txt File. I have opened the file with a office tool JARTE. Now it is easy to print my new class out. Remember back when you are a beginner in programming. I realised that Pharo has a huge "Tracking Tools" for engineering concepts and code. Only step by step learning is possible. Thanks again , and have a nice week. See you next time , for other Pharo matters , in this "Cinema". Hans Hello again , i have searched for a new text file in the Pharo Image folder that contains the printed version of my class. There is no text file. I have chosen the "file out " option in Pharo version 3.0 and the book version PBE one click 1.1. At the moment i have only PBE in use for learning. There is my new class created. If you want i can make a screen video and sending with e-mail of the "File out" session , that you can see , that there is no new text file. regards hans Just one thing for description of the hardcopy : Yes ; a browser inside the system is much better. The only reason to make a hardcopy in the form of a list is to have a "Analog view" of the interdependencies of the whole package. You know that in the job as electrician. You can measure the power from a plug with a digital or with a analog meter. Or with a combination of that. I am only a beginner. But to have paper makes the opportunity to make lines and notes with interdependencies REAL in ONE view. Such like to make a flow diagram of the whole Software in Basic language. ( My languages are Smalltalk 80 and Liberty Basic. ) Regards Hans Thank you for the answer. I have chosen " FILE OUT ". Let me aks : Who is the file then. On what location ? " I only have seen that Pharo has make a snapshot of the " Package-Class-Protokoll-Methods". After this snapshot the printer is not started. Therfore i suppose that a File has been made in any Folder. Regards Hans Hallo fellows, i have just started with smalltalk programming Pharo. Could you help me in one question please ? Its simple : After already performed a own NEW CLASS in the class browser , it is very convenient to PRINT OUT the complete Class , together with protokoll and methods in a LIST FORM , in HARD COPY on a Printer. Just to "have" the class and see it on real paper. I couldnt find any advice in books or help. regards Hans

Re: [Pharo-users] [squeak-dev] Using libraries in FFI

Try to run pharo with strace. That way you will see all syscalls including libraries opens that pharo does attempt. That's what I do when trying to figure out such things.

How to force FFI to load a library

Hi, I have one library which depends from another one. How can I force pharo to load the dependent library ? Annick

Re: [Pharo-users] [squeak-dev] Using libraries in FFI

by Annick Fron

Hi Eliot, My problem is not with the VM, my problem is with my own library that I connect to through FFI. I know where the libraries are ! I have tried to add them in /etc/ld.so.conf.d , that does not work. I have tried export LD_LIBRARY_PATH, but somehow it erases some libraries needed by pharo. I have done sudo ldconfig ... In fact I have one library that depends from another one. In FFI I call one method which calls another method in the other library. I have tried to create symbolics links in the directory â¦ I have checked that nm gives the right symbol with the right type .. So I have no idea what to try now !

The squeak script that comes with the Cog VMs extends LD_LIBRARY_PATH, so if you know where your libraries are you can use the script to find the other libraries the VM needs (c library and plugins). > > Eliot (phone) > > On Oct 22, 2014, at 2:55 AM, Annick Fron <list(a)afceurope.com> wrote: > >> Hi, >> >> I am using a module in FFI which depends on a large library letâs say 10 dynamic .so files in a directory. >> How is it possible to use this library without making all symbolic links ? >> >> Annick >

Good overview and advice, Kilon - just give it a try, Hans. And in any case, draw pictures and take notes on paper while your browsing and studying the code, that always helps. > On Wed, Oct 22, 2014 at 1:56 PM, Hans Schueren <werbung(a)hans-schueren.de> wrote: > > > Just one thing for description of the hardcopy : > > Yes ; a browser inside the system is much better. > > > The only reason to make a hardcopy in the form of a list is to > > have a "Analog view" of the interdependencies of the whole package. > > > You know that in the job as electrician. > > You can measure the power from a plug with > > a digital or with a analog meter.

nothing wrong in doing things the old / analogue way but pharo offers a variety of tools to help you visualise and understand code. One example is when you want to know how one class is a subclass from another. Browser has a separate view for this called Hierarchy view. Another is when methods are get overriden either in the class you currently viewing or in a subclass, browser has special icons to inform you of that. Clicking on those icons will send you to the overriding methods. If the method has a test you can use as an example there would be an icon for it too, clicking it will run the test for you. What if you see a method used and you want to look into its definition ? You can use the browser to do that or your printer paper but right clicking on the method and going directly to its definition is way faster also it will show you what other class defines such method. Then of course you have the finder tool that allows you to search using just a few letters methods, classes and source and even allows you to provide an end result and gives back which method can produce that end result etc The bottom line is that there are many pharo tools at your disposal and they are extremely powerful. There are also a lot of third party tools as well, for example if you want to create a diagram of the algorithm of an application / package you can do that using Roassal. So I would say for time being stick with Pharo learn the tools and if you are not happy then print code and use your pen to create diagrams of its logic.
