Re: [Pharo-users] Glorp + P3 + SQLite

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 don't get anything really intelligible out of the error. I get a debugger.

New to Pharo. "Could not coerce arguments" (Problem with character encoding?) + Learning resources?

by M O

Hi, I'm new to Pharo, and generally, in programming. I decided that my first programming language is going to be Pharo. However I have encountered some issues when I was exploring some examples. I don't want them to bother me later, so I'd like them to be resolved as soon as possible. Some info: OS: Windows 8.1, language Polish, Pharo version: 7 stable 64, Pharo Launcher installed in C:\PharoLauncher, images and VMs located in C:\users\<user>\Documents\... My Windows account (admin user) username contains non-ASCII character ("Å"). I tested all cases below on account with only ASCII characters ("Administrator") and they all work just fine. Therefore I strongly suspect the main source of issues is character encoding but I have no idea how to solve it or if it's actual problem. Noticed that #1 and #2 fails when attempting to perfom FFI call Here's the list of things with issues I encountered: 1. AthensDemoMorph example (Args-1 and Args-2) 2. Downloading packages from git repository (Git-1 and Git-2) In second example it goes straight to downloading from git repo, while first throws error 1. Pharo Mooc (Mooc) Instead of "Å" there are displayed some "rubbish" characters I opened debugger in case #1 and #2 (On personal account) and noticed that variable "ec" (error code I guess) has value 29 (See "invokeWithArgs") in method "invokeWithArguments", and variable "errCode" has value 6 (See "externalCallFailed") in method "externalCallFailed". I guess those values are related to Windows error codes so I looked them up on Microsoft site. For 6 I found it's error "ERROR_INVALID_HANDLE", while for 29 it's "ERROR_WRITE_FAULT". As I mentioned above, this might be character encoding problem, but this is just my guessing. Hope you can help me resolve it. Second thing I'd like to ask is, what are best up to date learning resources for Pharo? I'm mainly concerned about tools. I know a bit about idea of "real" OOP (from Alan Kay's talks). Is Mooc (http://mooc.pharo.org/) and Pharo by Example 5 enough for start? For Mooc, do I need to use Mooc image (It uses a bit outdated Pharo version) or can I use simply Pharo 7?

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 -- Pavel so 19. 10. 2019 v 10:27 odesÃlatel Todd Blanchard via Pharo-users < pharo-users(a)lists.pharo.org> napsal: > 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.

Pillar in-image rendering (was: String concatenation vs. Stream)

Norbert I have the basic pillar rendering done: headers, lists, bold, emphasis, images, links (including a âopen browser on methodâ 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 <https://github.com/pillar-markup/pillar/pull/391> there before I can be a modular extension. Iâll 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.

Re: [Pharo-users] Glorp + P3 + SQLite

by 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 ?

Glorp + P3 + SQLite

by Todd Blanchard

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.

â¦ namely, I was thinking about porting ActiveRecord - if I'm not mistaken, Alan's AR is not implemented yet in Pharo. It would be nice to have a "whole package" as SQLAlchemy+Reflection and Entity Framework Database First.Â Not all the projects are mission critical and this kind of tools are very handy.
