[Pharo-users] Glorp + P3 + SQLite

[Todd Blanchard via Pharo-users]

--- Begin Message ---
I loaded GLORP+P3 without issue.

Trying to load SQLite3 - it also wants to load GLORP which complains of 
conflict.

For P3 I used:

Metacello new
   baseline: 'P3';
   repository: 'github://svenvc/P3';
   load: 'glorp'.


For SQLite:

Metacello new 
repository: 'github://PierceNg/glorp-sqlite3:pharo7';
baseline: 'GlorpSQLite';
load.

but this fails with a conflict.  I suspect the conflict is it wants to load in 
glorp again.

I would also like to have mysql driver at some point.

Any tips for getting these to play nice together would be great.--- End Message ---

I started to do exactly the same. Well I started to do a converter between 
pillar markup and text attributes, but I think you do the same. We probably 
should talk. Is you code anywhere public?

[Sven Van Caekenberghe]

Hi Todd,

Both specify their dependency on Glorp almost the same way:

P3:

spec baseline: 'Glorp' with: [ spec repository: 
'github://pharo-rdbms/glorp:master/'].

Sqlite3:

spec baseline: 'Glorp' with: [ spec repository: 'github://pharo-rdbms/glorp' ].

What exactly is the conflict ?

[Pharo-users] Pillar in-image rendering (was: String concatenation vs. Stream)

I have the basic pillar rendering done: headers, lists, bold, emphasis,
images, links (including a “open browser on method” link).

My main *remaining issue is to do tables* somehow. Any hints on how to
render tables inside a text?

It is not on github atm - I need a pull request to come through
 there before I can be a
modular extension.

I’ll try to get it up on my own github sometime Monday.

I am currently working on a github markdown -> pillar tree (the internal
rep of pillar). I estimate I am a few days out from that one.

Best,

Kasper

[Pavel Krivanek]

Btw. there exists an updated version of Glorp:
github://pavel-krivanek/glorp:8.3.1-23-baseline
But the compatibility of it with SQLite was never tested

I should probably mention that I do not really have a great handle on how 
package configurations work these days.

Coming back to Smalltalk after a long time away.

Pointer to an explanation of how package configurations work would be great.

I think you found two things that will make it harder to use the Pharo
environment:

   - Windows 8.1 is not a recent version of an OS, and therefore much of
   the community who develop Pharo won't be able to guarantee support for it.
   I suspect it's the cause of the problems #1 and #2 (FFI), but it's hard to
   know as I don't have Windows 8.1. But as you have seen, some things are
   working, so some learning might be possible. A possible solution for you
   could be to run Linux in a VM on your Windows 8 machine and use Pharo for
   Linux. The Pharo Launcher and other things work in a similar way under
   Linux, although installing linux is a big distraction from your goal to
   learn Pharo and programming (which often happens in information
   technology).
   - The use of non-ascii characters in the path (in Windows) has been a
   source of bugs (e.g.,
   https://github.com/pharo-project/pharo-launcher/issues/333 but it's not
   only in Pharo). As you have already found out, you can use another account
   (maybe you can call it Pharo) without special characters.

*Second thing I’d like to ask is, what are best up to date learning

The MOOC is a great place to start for the content (the videos and the PDFs
are helpful). Pharo By Example 5 is also good. There are small differences
in the GUI that sometimes trip up new students.

Do you know of exercism.io? There is a Pharo track there, and you can
always ask for help with those challenges using the #exercism channel of
the Pharo Discord server  https://discordapp.com/invite/QewZMZa

Re: [Pharo-users] Import a pharo 6 image in pharo 7

[Oswall Verny Arguedas C.]

Thanks Sean and Sven

I'm going to investigate Ston and Fuel to do it.
I also thought about passing the data to CouchDB (document database) and
then accessing from a clean Pharo 7 with Seaside and Bootstrap.
How do you think the status of the drivers for Pharo for CouchDB is
currently. I used it for an application for production. Also Mongo but he
changed his license.
Thanks in advance
Oswall

Re: [Pharo-users] Import a pharo 6 image in pharo 7

[Alejandro Infante]

I wouldn’t recommend Mongo for this use because it doesn’t automagically 
resolve cycles, so you would have to do a lot of work in order to serialize the 
data. I agree with the previous suggestions and use Fuel or STON.

Cheers,
Alejandro

+1. Either of these methods is pretty much a one-liner. The main hiccup with
Fuel is installing the same Fuel version in both the source and target
images.

Todd, to load SQLite3 only:

  Metacello new
repository: 'github://astares/Pharo-UDBC/src';
baseline: 'UDBC';
load: 'SQLite'
