Re: [Pharo-users] inserting special character 'vector angle' symbol

by Paul DeBruicker

Do you have a font on your computer or better yet in Pharo that can display it? Where do you want to display it (web, image, etc) ?

inserting special character 'vector angle' symbol

by Ben Coman

I need to display electrical phasors (which are complex numbers in polar notation). This requires a special 'vector angle' symbol as shown http://www.allaboutcircuits.com/vol_2/chpt_2/5.html. What are my options for displaying such a symbol? â My searching only turned up 'Character characterTable' I wondered if I can replace one of those bitmap characters with my own. I also found an online character set converter http://kanjidict.stc.cx/recode.php which converted from the character from ISO-8859-1 to UTF-8 "∠" but that result doesn't mean a lot to me. Hints would be greatly appreciated. cheers -ben

Re: [Pharo-users] parse iCalendar (rfc2445) recurrence rules into a Schedule?

by StÃ©phane Ducasse

Hi paul I looked around and I found iCalendar, vCalendar and vCard I imagine that this is the one you found. And indeed Yann Monclair worked on ical.

Hi Stef, Thanks for getting back to me. That library does 90% of what I want so I'll take a look at adding the last 10% sometime. was just hoping to be able to skip adding the last 10% Paul On 12/06/2012 01:21 PM, StÃ©phane Ducasse wrote: > Hi paul > > I do not know if there is a parser.

Hi paul I do not know if there is a parser. What I know is that the package on ss was developed during lecture I gave at bern and used in DabbleDB (I do not know if they extended it - probably).

parse iCalendar (rfc2445) recurrence rules into a Schedule?

by Paul DeBruicker

Hi - Is there a package that will convert an iCalendar (*.ics file, rfe2445) VEVENT and its recurrence/exclusion rules/dates into a Schedule in pharo or squeak or gemstone? I've seen the iCal package on Squeaksource but it doesn't seem to interpret the RRULEs into anything other than their constituent parts. Thanks Paul

I think it is the same story as with the FileSystem... They will have to exist for some time in parallel, which will work fine since they don't share the same protocols. Then we have to do a major move towards a small legacy layer, again like in FS, and then start to rewrite things step by step to the new Xtreams. The current streams are so horribly broken that I think there is little to no chance to fix it from within. Maybe wrappers like Sven did will temporarily work around the issues, but they are poor solution compared to Xtreams. I remember Sean loaded and made Xtreams work in 2.0 and the couple of test failing were related to the FS changes from 14 to 20. And yes we might sweat some blood until the thing will properly run, but it will be worthwhile. Remember how much cleaner we are with the new FS. And I think the streams are even worse than the old FileDirectory was :)
