Hello Lionel, to build user interfaces I recommend that you use Spec. Many user interfaces in the standard Pharo image are written using it. I am currently writing documentation for it, here is the introductory chapter: > On Jul 10, 2016, at 20:32, Lionel Akue <lionelakue(a)gmail.com> wrote: > > Hi > > I am making a library to accelerate the building of management software. > > I am looking for existing libraries: > > for UI.

There is roassal if you need to visualize data. I have seen people visualizing relations between software artifacts.

Re: [Pharo-users] [UFFI] Using a nested structure

by Henrik Johansen

The alignment calculation of external enums is wrong, it should be FFIExternalEnumerationType >> externalTypeAlignment ^ self representationType externalTypeAlignment It only manifests for 32bit platforms on Windows since that's the only one with a pointer alignment (which superclass FFIExternalReferenceType returns) of 8, not 4 (which is the same alignment as the correct FFIUInt alignment) Cheers, Henry > On 09 Jul 2016, at 12:08 , Merwan Ouddane <merwanouddane(a)gmail.com> wrote: > > Yes I did. > > Have you tried on windows ?

I've had the same problem. As people write in other topics - it's connected with over-caching this site. My solution was to use incognito mode of Chrome - login from scratch and project created just fine.

Re: [Pharo-users] SQLite + Pharo

by Hilaire

Hi Esteban, What is exactly thread safe from the Pharo perspective? Is Sqlite library handling the conflict of access, and put on wait an access not possible at a given moment, or does it signal it is busy? In the later case handling a wait may be necessary. I'm planing to use sql to manage users, groups, etc, then Fuel for business model where concurrent access does not exist. About Sql use with Smalltalk, I was looking for examples of best practice, but I did not find much. Thanks Hilaire Le 10/07/2016 16:24, Esteban A.

The SQLite shared library is thread safe by default, so you shouldn't worry about that.
