The main problem was I didn't what it's good about at all - load image for a version, runs it - what's the "wow it's great" about? Missed part was it loads correct vm; plus makes sense when you have hundreds (I don't). Now it must be combined with the startup script magic to work with long-time projects, but those are also new to me - did not know of them until your booklet, not using them at all yet.

Re: [Pharo-users] How do you store and manage small programs?

by Norbert Hartl

Andy, I use the filesystem for it. Letâs say you have a directory called âscriptsâ. If you inspect âscriptsâ asFileReference you get kind of a browser of the files in there. If the have the file extension .st syntax highlighting is enabled if you look at it. You can create new scripts there,too. I like that the most because the scripts are not in the image anymore and the probability to loose them is lower. I have a scripts folder in my home directory (global) and one in the project folder (project specific). And inspectors to bith location are opened by the script that prepares a new image.

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.

Hi Andy As you saw there are plenty of solutions. Now what I learned is that it is often better in the long to have a little object because suddenly it opens your mind and you realise that you can teach him something more. So I often find myself realising that I created some class methods and that it was stupid better have a real little object because it can do more and in particular for open new path So now I do not use scripts but plain little classes with nice little printOn: methods and arguments to get customized.

P3 timeout

by Pierce Ng

Hi Sven and all, I have a PostgreSQL database running in a resource-light Linux VM with ~4 million rows consisting of mostly text. My query executes regexp_matches() on the text and it runs noticeably slowly. I am encountering ConnectionTimedOut using P3 to run my query. PostgresV2 and Python's pg8000 do work though. I see that PostgresV2's PGConnection uses "Socket standardTimeout". I changed ZdcSimpleSocketStream class-side's #openConnectionToHostNamed:port: bottom part to add the same timeout because P3Client>>open calls it: ZdcSimpleSocketStream class>>openConnectionToHostNamed: hostName port: portNumber [...] ^ socketStream timeout: Socket standardTimeOut; "<== added this line" connectTo: hostIP port: portNumber; yourself Now my query returns instead of timing out. It does look like ZdcSimpleSocketStream's three class-side methods could use some refactoring love. Pierce

re Script Manager "We would recommend users to switch to QuickAccess which is a better script manager than this tool." QuickAccess here's a video and everything https://pharoweekly.wordpress.com/2015/11/06/quickaccess/ For QA I also have a startup script that installs it on first startup, and then reloads its state on every startup (so the scripts are shared between images) https://github.com/peteruhnak/pharo-scripts/blob/master/config/6.0/quickAcc… for "maybe-sometimes-useful-scripts" or when I just want to write a code memo for myself, I tend to use gist ( https://gist.github.com/peteruhnak ) Peter On Sat, Nov 25, 2017 at 6:51 PM, Offray Vladimir Luna CÃ¡rdenas < offray.luna(a)mutabit.com> wrote: > Hi Andy, > > On 25/11/17 12:34, Andy Burnett wrote: > > I have just created a couple of small playground scripts that do some > > useful data wrangling.

deselecting individual items with beMultiple

by Evan Donahue

If I have a gl fast table with #beMultiple enabled, is there a way for me to select non-contiguous items? Eg - item 1 - item 2 - item 3 Using shift, I can highlight items 1&2 or 1-3, but not 1&3, excluding 2. Some listing interfaces in non-pharo applications allow control clicking to deselect individual items from the middle of a selection. Is there something like that in Pharo glm presentations? Thanks

I use github and Package Browser, Package Browser is for intalling packages from inside image. For small code snippets I use Gist which supports Smalltalk syntax.
