Andâ¦ for those who do not understand the code names: - Aleph is an index system that keeps senders/implementors and references, making access to this queries almost automatic even in very big images. - This also speeds up all refactors, since they query for implementors and references all the time. - Spotter queries have been redesigned to not create the full list before showing it, but fetching the values using a generator. It also uses aleph (which in time uses a trie three) to fetch the results. Fuzzy matcher is gone here, but the gain is bigger than the lost. - Complishion is a new code completion framework who fetches also using generators, and also uses different heuristics to provide more âcloseâ answers instead just the list. Then, there is a not-so-small list of smaller changes, most of them applied directly to the image (but for those you need P9). In sum, we have speed up a lot the usage of Pharo in big imagesâ¦ but of course we will be waiting for feedback to go farther where needed :) Esteban > On 23 Mar 2020, at 10:29, Esteban Lorenzano <estebanlm(a)gmail.com> wrote: > > > >> On 23 Mar 2020, at 10:28, Esteban Lorenzano <estebanlm(a)gmail.com <mailto:estebanlm@gmail.com>> wrote: >> >> Hi, >> >>> On 23 Mar 2020, at 10:14, Vincent Blondeau via Pharo-dev <pharo-dev(a)lists.pharo.org <mailto:pharo-dev@lists.pharo.org>> wrote: >>> >>> >>> From: "Vincent Blondeau" <vincent.blondeau(a)lifeware.ch <mailto:vincent.blondeau@lifeware.ch>> >>> Subject: RE: [Pharo-dev] [Mm10] 2020-03-23 (WAS: No subject) >>> Date: 23 March 2020 at 10:14:12 CET >>> To: "'Pharo Development List'" <pharo-dev(a)lists.pharo.org <mailto:pharo-dev@lists.pharo.org>> >>> >>> >>> Hi Pablo, >>> >>> Great news!

Hi, Aleph is the fantasy name of the index manager. Basically, it is a set of indexes we are using on the image. As Esteban said, everything should work in Pharo 8, but it requires harvesting some changes I have made in the Pharo 9 image, so I will try to do it this week. Today I will try to fix some of the issues while generating the indexes the first time. The only issue is that it takes a lot of time, I want to reduce it to something usable.

Hi Vincent, see last Mm from Esteban (https://lists.pharo.org/pipermail/pharo-dev_lists.pharo.org/2020-March/2776…) which says: "release Aleph index system to speed up big images senders/implementors and all Refactors associated" It is found on https://github.com/estebanlm/aleph saying "an index system for the pharo system" Bye T.
