Re: [Pharo-project] Scripting with Pharo?

by Andrei Stebakov

Thank you, I'll give it a try. See, maybe my philosophy is wrong, but I'd rather get better at one tool (where it's possible) than learn multiple different tools to do similar tasks. I think Pharo has a potential to be if not a Swiss army knife like Python, but a very useful language for any programming tasks (scripting is one of them). So far, as a newbie, I like what I see in Pharo and having a blast learning it. I am so thrilled, that just a thought that it could do scripting sends shivers down my spine :) 2010/5/12 Gabriel Brunstein <gaboto(a)gmail.com> > What about coral? > http://scg.unibe.ch/wiki/projects/bachelorsprojects/coral > > 2010/5/12 Andrei Stebakov <lispercat(a)gmail.com> > >> Is it possible to start Pharo headless and execute some command (say to >> get some info from a web page)? >> >> _______________________________________________ >> Pharo-project mailing list >> Pharo-project(a)lists.gforge.inria.fr >> http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >> > > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >

Re: [Pharo-project] Scripting with Pharo?

its a bit heawyweight to use VM as command-line tool. you could, intead run pharo in persistent mode, and schedule the same piece of code to run periodically as background process in it. 2010/5/12 Andrei Stebakov <lispercat(a)gmail.com>: > I think that scripting support is essential for any interpreted language and > if Pharo had it, its community would grow much faster. > Let's say, I learned now how to use HTML parsing in the GUI version of > Pharo. > I went ahead and created my own class (or set of classes) in the image which > can say retrieve a dollar rate from some bank web page. > Now I should be able to run Pharo in a "batch mode" saying something like... > "./pharo -batch "DollarRateInfo :getAndSendEmail 'myaddress(a)domain.com". > This way I could schedule this command using cron to send me this dollar > rate via email every day at 2 pm.

Re: [Pharo-project] Scripting with Pharo?

by Andrei Stebakov

I think that scripting support is essential for any interpreted language and if Pharo had it, its community would grow much faster. Let's say, I learned now how to use HTML parsing in the GUI version of Pharo. I went ahead and created my own class (or set of classes) in the image which can say retrieve a dollar rate from some bank web page. Now I should be able to run Pharo in a "batch mode" saying something like... "./pharo -batch "DollarRateInfo :getAndSendEmail 'myaddress(a)domain.com". This way I could schedule this command using cron to send me this dollar rate via email every day at 2 pm. Having this functionality I could really spend more time using Pharo for different needs and get better at using it. I don't think it should be too hard to implement (please correct me if I am wrong). In the batch mode pharo would start in a "headless mode", read some input from a standard input (or from command line), execute it in a 'hidden' Workspace and send the output of the evaluation to the standard output.
