Iceberg issue on Ubuntu 16.04.3 Pharo 6.1

by Juraj Kubelka

Hi, I am trying to build a project in ubuntu 16.04.3. To this: - I downloaded Pharo 6.1 (60541) 64bit - I open the Pharo image and execute: Metacello new baseline: 'GToolkit'; repository: 'github://feenkcom/gtoolkit/src'; load. I have the following issue: LGit_GIT_ERROR: SSL error: error:140E0197:SSL routines:SSL_shutdown:shutdown while in init The full stack is below. I can clone the repository from a terminal using: git clone git@github.com:feenkcom/gtoolkit.git I believe that my settings are correct (same that I use on macOS): Is Iceberg suppose to work on Ubuntu 16.04.3 64bit? I have noticed that it works in Pharo 7 64bit (excluding the fact gtoolkit does not work in Pharo 7 yet). I found this bug report that might be related: https://github.com/libgit2/libgit2/issues/4644 <https://github.com/libgit2/libgit2/issues/4644> Thanks!

If you want to override that behaviour, AFAIR you need to override the #default group spec group: 'default' with: #( .... ) Actually, I've cloned your project and see that default is defined as download tools. So, how are you loading your project. Moreover, I've just tried it and it worked, so there is something else to it: - I've cloned SmaCC - I've checked out the flgr branch - I've loaded the baseline and added spec package: 'SmaCC-Reification' with: [ spec requires: #('SmaCC-Smalltalk-Parser' 'SmaCC-Runtime' 'SmaCC-Java') ] - then, I've done right click on the iceberg project and selected Metacello -> load baseline... => then inserted SmaCC-Reification and I got that package + dependencies loaded... > Moreover, my original problem is still there â it's looking in a > nonexistent package cache, rather than on github, or in my > ~/iceberg/apblack/SmaCC clone of github. > I don't think this is quite like that... Metacello will try to lookup the package in several places. And it will check at last the package cache. So it fails because it was not able to found that package in any of your repositories, but the last it checked was the package cache. > - If SmaCC-Reification is in a non-default group, you probably want to add > > spec > baseline: 'SmaCC-Reification' > with: [ spec repository: 'github://apblack/SmaCC:working'; loads: #( > 'NAME-OF-YOUR-REIFICATION-GROUP' ) ]. > > > This would go in the BaselineOfGrace package, right?

Ecstatic features in Pillar

by Ben Coman

I just saw a comment in the Ecstatic issue tracker that most of its features have been pushed to Pillar, which sounds really interesting. Could someone describe this and how to generate a static site? Also, anyone know of templates suitable for a small engineering consultancy? Just in the last couple of days a need has arisen for me to do this. cheers -ben

I can not find how to obtain that punctual value 2014.

It helps with this sort of thing to execute the code in a playground and inspect the result. One thing you need to know is that the result of xpath is almost always some sort of XMLCollection, even when there is only one element. I would expect the result you want if you write yearmem := (tree xpath: âcardset/card/yearâ) first. Note that you should not need a slash at the start; xpath starts searching in the children of the top node. Also you do not need to give every step of the hierarchy; you can always skip levels provided the result specifies a unique route to the node you want. So in this case you can write: yearmem := (tree xpath: â//yearâ) first.
