November 2017 - Pharo-users

How do you store and manage small programs?

by Andy Burnett

I have just created a couple of small playground scripts that do some useful data wrangling. The chances are that I will reuse them from time to time, but with tweaks. Does version 6 Have some way to store them? I think I am after a sort of scripts catalogue.

The Pharo-Chrome readme includes code for loading DataFrame: Metacello new baseline: 'DataFrame'; repository: 'github://PolyMathOrg/DataFrame'; load. If you are familiar with python pandas, it is a similar package for Pharo. See also: https://github.com/PolyMathOrg/DataFrame Cheers, Alistair

Re: [Pharo-users] Timespan translateToUTC problematic

by Stephane Ducasse

Thanks you all for this discussion. Last time I used Date and friends I got really frustrated. The navigation between the concept was not really good. I needed for example to manipulate a month in a year: February 2017 (I should check what I did). If I would have time and money I would - create a minimal package private only used by the kernel to load and save image and order changesets. - create a nicer package that we can use for app dev.

Thanks to Ben, Benoit and Sven for their input. I ended up using #equals: as suggested by Sven. I'd thought of this and had originally rejected it due to it being the same name (when spoken) as #=. But I've also added the other corresponding comparisons, and #equals: fitted in the best.

For example, I think it would be awkward for me to operate with OS locale set to Russian. You'll see little action on it until there is an Issue logged at pharo.fogbugz.com with a simple set of steps to reproduced for standard environments (i.e. using English locales) Reviewing your other posts, I'd suggest initially creating a script to wrap Pharo startup that cleans all the environment variables to ascii characters, temporarily creating required directories so at lest you can get it started. Then extend that script to reintroduce the error, like a single non-ascii character in a single environment variable that causes an error. That extended part then provides a path for others to reproduce your problem, which you would attach to the Issue. Then as you investigate a solution yourself, ask questions about it on pharo-dev to keep the Issue active and over time you'll likely get some action from others on it. cheers -ben

I downloaded the latest PharoLauncher image, use VM for Pharo 6.1. 1) On load i got an error with UTF8 encoding. 2) Every time i tried to create image (for example, Pharo 7 image) i get an error "Can't find the requested origin". Reported. Best regards, Vikenti Potapov
