[ANN] PunQLite - a new NoSQL wrapper for Pharo

by Masashi UMEZAWA

Hi all, I've developed PunQLite. UnQLite NoSQL database binding for Pharo. https://github.com/mumez/PunQLite http://smalltalkhub.com/#!/~MasashiUmezawa/PunQLite UnQLite is a fast, lightweight, portable, embedded KVS with a simple scripting engine (Jx9). http://unqlite.org/ Torsen kindly wrote about PunQLite project's beginning on his blog. http://astares.blogspot.jp/2013/11/punqlite-for-pharo-using-unqlite.html At that time, it was only a bare NativeBoost FFI interface. Now it has become a full-fledged wrapper. db := PqDatabase open: 'test.db'. db at: 'Smalltalk' put: 'COOL'. db at: 'Pharo' put: 'HOT'. db at: 'Smalltalk' ifPresent: [:data | data asString inspect ]. Transcript cr; show: db keys. db do: [:cursor | Transcript cr; show: cursor currentStringKey; space; show: cursor currentStringValue. ]. db close. Moreover, it is quite fast. I wrote a simple benchmark that does many round-trips (put/get 100000 small elements). The result is 877 msecs (on my windows laptop). It was impressive. Enjoy! -- [:masashi | ^umezawa]

Re: [Pharo-dev] Transparent colors with NBOpenGL?

by Ronie Salgado

Hi Alex, Translucent objects requires a singlepass lighting model, which I took the opportunity to complete and make it the default one. I put your example with a slight modification under R3Example>>translucentCubes Translucent elements require a reception of the message makeTranslucent since their rendering must be handled in a special way. They must rendered after all the opaque objects, in a back to front order without depth writing. Currently only depth writing disabling per element is supported, so their rendering is not going to be perfect, but at least some transparency can be seen.

The thing is what if you have different things in a handful of browsers? I think that it can make sense to use it in nautilus with tabs. Or be able to quickly browse previous filters.

Filter in Nautilus

by Alexandre Bergel

Hi! I have the impression that it would be great to reuse the filter lastly set when opening a new nautilus. For example, if I have a browser with the filter "^Roassal2|^Trachâ, I would like to have the same when opening a new browser. Am I the only one to feel this?
