Esteban's ChangeLog week of 5 November 2018
by estebanlm＠gmail.com Nov. 12, 2018

Nov. 12, 2018

Hello! This is my weekly ChangeLog, from 5 November 2018 to 11 November 2018. You can see it in a better format by going here: http://log.smallworks.eu/web/search?from=5/11/2018&to=11/11/2018 ChangeLog ========= 5 November 2018: ---------------- * I just [announced](http://forum.world.st/ANN-Pharo-v7-0-0-rc1-released-td5088221.html) Pharo v7.0.0-rc1. Now the real work begins... :P * I worked on [case: 22628](https://pharo.fogbugz.com/f/cases/22628): merge latest FFI-Kernel changes. Thing is, now there is some overlapping between FFI-Kernel and UnifiedFFI, because they changed it in some things we already solved in UFFI, but well... we will have to see this in the future :) * I made a small PR to add a fix that Eliot contributed to it: [https://github.com/pharo-vcs/tonel/pull/60](https://github.com/pharo-vcs/to… . Is an error that happens when a snapshot contains *only* method extensions. cheers! Esteban

Streams and FileDialog in Pharo 6 and 7
by Torsten Bergmann Nov. 11, 2018

Nov. 11, 2018

Hi, A question to those who worked on the new streams for Pharo 7: In PHARO 6 I used the following expression to open a file dialog and let the user choose a binary file: s := UITheme builder fileOpen: 'Choose a file' extensions: #('exe'). This returned - either nil (when file dialog was canceled) - a "MultiByteFileStream" instance when a file was selected The MultiByteFileStream instance already had the name of the file (= full path) and I was able to query it for further use: s := UITheme builder fileOpen: 'Choose a file' extensions: #('exe'). s name inspect (for instance to display which file is processed in a window by showing the full path) Now in PHARO 7 same expression returns an instance of ZnCharacterReadStream (as MultiByteFileStream is deprecated): s := UITheme builder fileOpen: 'Choose a file' extensions: #('exe'). and ZnCharacterReadStream does not understand #name - and in fact the info about the name is totally lost/not available. To me this looks missing/broken. So what is the recommended way in Pharo 7 to open a file dialog, let the use choose a file and get a file stream but also the name? IMHO this is either broken or missing... Thanks T.

WELL512 PRNG
by Sven Van Caekenberghe Nov. 9, 2018

Nov. 9, 2018

Hi, By accident I came across a pseudo random number generator that I never heard off before. It is supposed to be pretty good and had a very simple implementation. So I ported it to Pharo. <class comment> I am RandomWELL512, a random number generator. I use the PRNG (Pseudo Randon Number Generator) WELL (Well equidistributed long-period linear) with a 512 bit state. https://en.wikipedia.org/wiki/Well_equidistributed_long-period_linear http://www.iro.umontreal.ca/~lecuyer/myftp/papers/wellrng.pdf Implementation algorithm (See #nextUInt32) http://www.lomont.org/Math/Papers/2008/Lomont_PRNG_2008.pdf (Chris Lomont, www.lomont.org) Usage RandomWELL512 new in: [ :r | (1 to: 10) collect: [ :i | r nextUInt32 ] ]. RandomWELL512 new useUnixRandomGeneratorSeed; in: [ :r | (1 to: 10) collect: [ :i | r next ] ]. RandomWELL512 new in: [ :r | (1 to: 10) collect: [ :i | r nextInt: 1000 ] ]. RandomWELL512 new in: [ :random | | count all | random useUnixRandomGeneratorSeed. count := 1024 * 1024. all := Array new: count streamContents: [ :out | count timesRepeat: [ out nextPut: random next ] ]. { all min. all max. all average. all stdev } ]. [ RandomWELL512 new in: [ :random | 1 to: 1e6 do: [ :i | random next ] ] ] timeToRun. Note that you should create one instance, seed it properly, and keep using it. </class comment> It is acceptably fast, generating 1M [0,1) Floats in about 0.1s. I compared the output with a fixed initial state to the C code that I started from and I got the same numbers. Maybe some people find this interesting. I attached a file out. Sven

PharoLauncher : Image version determination error
by Julien Nov. 9, 2018

Nov. 9, 2018

Hello, Is there something wrong with the latest Pharo 7.0 32bits image? I got this error from Pharo Launcher: Cannot determine image version: image version file not found! Try to run this command in a shell to get more information on the problem: cd "/Users/julien/Documents/Pharo/vms/private/6521/Pharo.app/Contents/MacOS" && "/Users/julien/Documents/Pharo/vms/private/6521/Pharo.app/Contents/MacOS/Pharo" --headless "/Users/julien/Documents/Pharo/images/RTFExperiment-Iceberg/RTFExperiment-Iceberg.image" eval "(Smalltalk imagePath asFileReference parent) / 'pharo.version' writeStreamDo: [ :stream | |major minor| major := SystemVersion current major. minor := SystemVersion current minor. (major = 6 and: [ SystemVersion current highestUpdate >= 60509 ]) ifTrue: [ minor := 1 ]. stream << major asString; << minor asString ]" When trying to start it. If I run this script in the terminal, nothing is print but the process crashes returning 1 as exit code. Can someone relate this issue as well?
