could not agree more, this is a great tool with a huge potential and really upgrades the Pharo experience. I have not see anything similar in other IDEs I have been using in the past.

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?

Re: [Pharo-users] Extending GTSpotter

by Tudor Girba

I would like to get Shift+Enter (because Cmd+Enter will be useful in other contexts), but we wanted to have something that can live next to the Spotlight for a while. But, now that we are over the first set of problems, I would like to use Shift+Enter. Any objections?
