Wanted: Companies using Pharo
by Marcus Denker Aug. 28, 2025

Aug. 28, 2025

We have a list of Pharo Companies at https://pharo.org/Companies A problem of course was that the list got out of date quite quickly. We now have improved it: - there is a form to add a new company - the contact person will get a link to update the infos at any time - the system sends a mail every year to the contact to remind to check if the data is still current - website is rendered directly from the data The current page still has a simple rendering: all companies alphabetically. But with the data we will be able to improve this step by step, so consider adding the info not currently used (e.g. map position, logo...) Future: - nicer page, e.g. with company logos - check links regularly (and send mail in case it is broken) - interactive map For now, the page contains both the new and the old list, with the idea of removing the old entries eventually. (If you are on the ESUG Mailinglist, you might have seen that we did the same for ESUG, for Smalltalk in general. The link to add your company there is https://esug.org/companies.html ) Marcus

Clean Blocks in Pharo 14
by Marcus Denker July 15, 2025

July 15, 2025

We have enabled the "Clean Block Closure" option for Pharo14 # What is this? Until now, blocks are created at runtime, but there are blocks that actually do not need any runtime data to be created. Thus "Clean blocks" are those blocks that - do not access self - do not access instance variables (which needs self) - do not return - do not access temp variables from outer blocks or the method With the clean block option enabled, the compiler can create the object at compile time. For Pharo12, we already enabled a sub-set: Constant Blocks. Now we do the next step: pre-create *all* clean blocks. # What is the effect? Positive: - much faster (we see a factor of 9 speedup for creating a block like [1+2] ) - the resulting block does not reference the outer context / self => GC can cleanup more - #isClean check on blocks is *much* faster (nice if you check for it e.g. for serialization) But: This means that we now have blocks that have no outerContext and #receiver returns nil. All code that relies on these needs to be changed to take this into account. We enabled Clean Blocks early in Pharo14 so we find all remaining problems, especially related to external code. So if you see strange behavior (especially in the debugger), please open an issue on the issue tracker! We are interested, too, in cases where you rely on either the receiver or the outerContext for blocks in your own code. # What next? - Deprecate #receiver on BlockClosure - Track down all remaining problems (e.g. debugger) After: - we want to enable to option to only reference the outerContext only for those blocks that need it (that do a non-local return). (there is a compiler option already, but disabled by default) - only blocks that access self should hold onto the receiver - .. and more
