If I'm not mistaken, all you have to do is add '/feed/' to the URL, like https://smalltalk.tech.blog/feed/. Of course, I don't /really/ know what the f*ck I'm talking about. horrido wrote > I don't know anything about RSS.

Re: [Pharo-users] Workspace with reliable save feature

by Offray Vladimir Luna CÃ¡rdenas

Hi, Also you can use Grafoscopio[1], to save longer nested scripts and combining them with longer prose. It also needs some love and to be ported to Spec2. I will start with testing it on Pharo 8 and slowly port it to Spec2. Any help is welcomed :-).

Re: [Pharo-users] Workspace with reliable save feature

by Torsten Bergmann

Hi Hilaire, ScriptManager and QuickAccess come to mind. I guess ScriptManager would need some love and a port to Spec2. But I guess QuickAccess could be easily used. It also has Spotter integration and you can import / export your script actions. Project including video is on https://github.com/astares/Pharo-QuickAccess Should be available in Catalog too Thx Torsten > Gesendet: Mittwoch, 22.

Re: [Pharo-users] Embedding pharo in C++

by tesonep＠gmail.com

Hi Roland, the function vm_main_with_parameters() starts the vm and it will not return until the image finishes. In my example, only when the SDL window is closed, the quit primitive is executed and the function ends. To do a nicer POC we need to make modifications in the image, so it handles keeping the image open.

Workspace with reliable save feature

by HilaireFernandes

Hi, Do we have an external workspace with a deterministic save feature. I looked at the catalog but found none, Both Workspace and Playground fall short. Workspace save file with 0 byte of content! Playground, with my experience with student, is absolutely not reliable to save script, its auto-save feature always results in lost of code. Particularly when combined with its rename and its inexplicit save behaviour. It is not practical to edit script and save code. I will start a second round of coding with students (12-14 yrs old) and I need them to save their code. The only viable option I see is to ask them to copy and to past their code in an external editor ! It will be a mess for sure and waste of time and energy. Any alternative idea or option I failed to see ? Hilaire ----- http://drgeo.eu -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Generate class hierarchy from JSON Schema

by Todd Blanchard

That would be amazing! I'm a Mac/Unix guy so I don't have access to the other platforms (I suppose I could fire up an AWS Oracle). I can do mysql/mariadb, posgresql, and sqlite. I'm pretty close to pushing my ActiveRecord extensions. I just need to get many to many with link tables done and it is good to go. I spent a few days "porting" the ruby inflector and its tests. As for database introspection, I am relying on this new method and the result set format on DatabasePlatform. printSqlStatementToListColumnsInTable: aDatabaseTable inSchema: schemaString on: aStream " Format: name | type | length | nullable | default_value | pk -------------------------+-------------------+--------+----------+-----------------------+---- id | character varying | 255 | 0 | ''::character varying | 1 Then I can build a whole class model and descriptor system off the schema. > On Jan 22, 2020, at 9:55 AM, TomaÅ¾ Turk <tomaz.turk(a)ef.uni-lj.si> wrote: > > Thanks, Todd - I'll prepare a PR for https://github.com/pharo-rdbms/glorp <https://github.com/pharo-rdbms/glorp> to update SQLServerPlatform and OraclePlatform. > > I already used the standardized query results format in PharoADO which works nicely with Glorp. You can find PharoADO here: https://github.com/eftomi/pharo-ado <https://github.com/eftomi/pharo-ado>. Maybe it can be included into the pharo-rdbms collection if you feel that it's mature enough.
