I do have utility classes with a lot of methods acting as a facade to the system, so that one can use it in a workspace easily. Now, these are used in a script to do things like: AcmeSystem stop; resetAllCaches; reloadConfiguration; ... start. These would be in a AcmeSystemStart.st that gets loaded by the headless image on the server with the st command line handler. Also useful is that I do have a command line handler that is wrapped with a acmetools.sh script that calls into the AcmeSystem class for administrative tasks, like in: ./acmetools.sh --list-users ./acmetools.sh --createUser xyz --...

how do you use scripts?

by Tudor Girba

Hi, As input for designing new features that better support scripting in Pharo, we would benefit from a bit more input around the role scripts play in your development life. To this end, I would like to invite you to share your scripting experience. Here are some questions to start from, but feel free to diverge: - What kind of actions do you put in scripts? - Do you rely on script files stored on the disk at all? - Where do you store your scripts (in one folder, in many folders)? - Do you version your scripts? - Do you store them in separate files with dedicated names, or tend to put multiple snippets in one larger file? - Do you rely on the names of the scripts? - Why do you use a script file and not a class? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

I find it a bit complicated to find about Pharo/Smalltalk questions in an easy way. Searching by tag (Pharo) gives a list of old questions. How do you get the last questions in an easy way?

(Ring?) Working with 'virtual' code entites

by Yuriy Tymchuk

Hi everyone! As you may know Iâm working on code quality/smells/critics. And I want to analyze bigger projects like Moose for example. But Moose works on Pharo3 while my system works on Pharo4. Is is possible to somehow obtain Classes and methods from the repository and perform some analysis on them without installing them in the system? Because in my general workflow I just create a collection of classes like: `packages flatCollect: #definedClasses` and then work with them. So any suggestions are welcome :) Cheers. Uko

SODD

by Yuriy Tymchuk

Hi, so this message is about SODD (Stack Overflow Driven Development) and Pharo/Smalltalk. If you look at the last questions of this guy: http://stackoverflow.com/users/1906070/shiran?tab=questions <http://stackoverflow.com/users/1906070/shiran?tab=questions> you can see that they are about smalltalk/squeak and asked in last 2 days :). In fact I think that we should support asking questions on SO, as a lot of people are anxious to register and talk to others on mailing list, and prefer to search for solutions on SO. If weâll build reasonable amount of Q/A data, it can be easier for other people to start with Pharo. Cheers! Uko
