A playground for Markdown?
by Offray Vladimir Luna CÃ¡rdenas Jan. 9, 2018

Jan. 9, 2018

Hi, Playgrounds are a really good way to write short snippets of code and I wonder if such experience could be extended for larger pieces of Markdown. What I'm thinking of is have something similar butÂ like this: 1. Support for Markdown instead of Smalltalk, including syntax hightlighning and tab behavior (a tab equals two spaces). 2. Clicking on urls should load the respective web page. Clicking on images shouldÂ show an image preview. That's it, to start with. At some point it could be using GT Documenter previews, font support and so on. But I would like to start by extending the playground to just support this two features. Any advice about where can I start for the first feature? Thanks, Offray

Re: [Pharo-users] Is there a way to stop arrays sorting automatically?

The problem was simply that I hadn't understood what it was - quite clearly - telling me. Now that I understand the problem, the explanation makes perfect sense :-) Cheers Andy

Formatted print for Duration
by Julien Jan. 7, 2018

Jan. 7, 2018

Hello, I do not see how to do a formatted print from a duration. I would like to be able to do something like: String streamContents: [ :s | 90 minutes formatted: âhh:mmâ printOn: s ] The Duration>>#printOn: method prints the ANSI 5.8.2.16 format: [-]D:HH:MM:SS[.S] The Duration>>#printHumanReadableOn: is not printing in the format I want. Am I missing something or such feature does not exist actually?

Exception in Gofer with Pharo 7
by Rafael Luque Jan. 7, 2018

Jan. 7, 2018

Hi all. I'm trying to load some packages from SmalltalkHub and I get an exception because ByteString did not understand #asUrl. Maybe it is related with String>>asUrl deprecated? https://pharo.fogbugz.com/f/cases/2896/Deprecate-String-asUrl Thank you!

Henry said >>>> It's not broken, but certainly deserves a comment as to why it operates inline; In the general case, one should not use/care about any given permutation outside the block. Allocating n! instances of an n-sized array by default, is a bad tradeoff considering performance degradation for uses where n >> 3. In the first case, a user can add a simple #copy, while in the second case, a user would probably want/have to reimplement the method entirely. <<< Thanks, that makes perfect sense. I will have a go at adding a suitable comment. Cheers Andy >

Grafoscopio (Initial) Feedback
by Sean P. DeNigris Jan. 6, 2018

Jan. 6, 2018

Thanks for this exciting project! I'm very intrigued after reading some of your blog posts because I have been actively working with big data in Pharo, but mostly by hacking/cobbling things together without a proper toolset/community. Here are a few things I noticed as I started playing around: - Maybe you should change the load command in the StHub readme to: ``` Metacello new smalltalkhubUser: 'Offray' project: 'Grafoscopio'; configuration: 'Grafoscopio'; load. ``` - the current script is in an old form - it also hardcodes Pharo 5 - This would greatly simplify the load via script instructions in the manual - Is it supposed to load in Pharo 6.1? I got `OrderedCollection DNU #asSymbol from #listOutdatedDocsIn:. I stubbed out #isUpdated to return true and it loaded. - Do you have any plans to move to git? I would love to contribute, but I've been spoiled by GH and I just don't have the energy to go back to the mcz (barrier filled) contribution process ha ha - I found the intermixing of gray and color buttons confusing. I assumed that the gray ones were disabled. - I wonder if labels on the node title and link edit fields might help discoverability - All the export formats seem to end up saving to markdown. I assumed this is because I'm missing an external library? Either way, it would be good to get some feedback on why it doesn't work as expected and how to make it work. Thanks again. Keep moving forward!! ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Examples of Garage for DB2
by Andrei Stebakov Jan. 5, 2018

Jan. 5, 2018

I need to be able to navigate DB2 connection. As we discussed it a few days ago on the mailing list, the suggestion was to use Garage. I downloaded Garage to my Pharo 6.1 on windows. But in Garage I only see drivers for MySql, Postgres and Sqlite3. Does it mean that for DB2 I should look somewhere else or there is a way to create a connection for DB2 using existing Garage functionality? If there is a way, could you send some example? Thanks! Andrei
