AbstractLayout class comment

by Ben Coman

Minor thing... AbstractLayout class comment says... "There are special cases of layouts without slots, like NilLayout or BitsLayout." but I see no NilLayout in the system. Did this become EmptyLayout? cheers -ben

Re: [Pharo-dev] comparison statistics

by Ben Coman

Of course the saying goes "There are three types of lies: lies, damn lies and statistics" But assuming some estimate with no data is equally fallible. Yes the committers list is obviously just "main developers" but equally as I consider the names on the Pharo About page, these are not drive-by one-bug-fix contributors. One significant difference between contributing to Pharo and contributing to Python is the additional barrier of entry to *stop* developing you application and "invest the time to learn the tool chain(s)(make, ReST, regrtest, svnmerge/svndiff, sphinx, etc)" [1]. Python users are more likely to workaround an issue [2]. Whereas in Pharo, the system comes ready to debug by default. Your workaround with Pharo is as likely to change something in core system code as change something in your app code.

Allow me to be very skeptical, are you sure your numbers is not main contributors because I find it hard to believe that Python that has around 2 million coders world wide https://blog.pythonanywhere.com/67/ has ONLY 92 total contributors ? I would assume an estimate of around 1000 including those that have just one simple bug fix.

Re: [Pharo-dev] comparison statistics

by Benoit St-Jean

It could also reflect the complexity of the environment.Â A lot of stuff can be done in waaaaaaaaaaay less lines of code in Pharo than in C for instance.Â Hence, we need less developers in Pharo/Smalltalk to do more stuff!

Just bumped into some interesting statistics to consider when the minor worry occasionally arises that Pharo is not more popular.

Re: [Pharo-dev] FFI callout arguments - references to internal objects

by Esteban Lorenzano

Hi Ben, I will take a better look tomorrow morning, but as first sight, seems to be that you want to declare SomeObject and receive it as argument to the callback, while you are receiving just an ExternalAddress. If is that the problem what happens is that callbacks do not handle *any type* as the rest of UFFIâ¦ they just handle standard C types, so you will receive an ExternalAddress isnât? You need to obtain the actual object as you need it. I see two strategies: 1) just create the object using SomeObject>>#fromHandle: This work fine if object is stateless and just want to access itâs defined vocabulary. 2) orâ¦ you can just cachÃ© the data someplace and then find it using the ExternalAddress as index. (I hope I interpreted the problem correctlyâ¦ Iâm a bit sleep here :P) cheers, Esteban > On 24 Sep 2016, at 19:40, Ben Coman <btc(a)openInWorld.com> wrote: > > I'm seeking some support for Part 5 of my FFI tutorial > http://blog.openinworld.com/2016/09/pharo-libclang-ffi-part-5-client-data-a… > > where I'm trying to replicate some C code where: > * client_data is a void pointer, and an argument to a callout function > * a reference to some data (an int, or a struct) is passed to the > callout function as the client_data > * the callout function passes that same client_data to a callback > function which casts the client-data to the required type > > How can I replicate that with UFFI?

Hi sean What I mentioned what really worse. You would select a piece of text and you would lose some characters at the end. So I do not think that it is link with your report.
