I've found it a minor annoyance but sufficient to to close and reopen an image to reset things, but being able to do it live in-Image is really nice.

Non-ASCII characters are not allowed in a URL (in its external string representation, the input of the parser), they must be encoded. When you construct a URL from parts, the encoding will be done for you, as you specify unencoded elements. 'https://en.wiktionary.org/wiki' asUrl addPathSegment: 'prÃªt'; fragment: #French; yourself. => https://en.wiktionary.org/wiki/pr%C3%AAt#French 'https://en.wiktionary.org/wiki/pr%C3%AAt#French' asUrl. And you would be correct to remark that web browsers do allow this, which is more a UI thing. > ----- > Cheers, > Sean > -- > Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html >

I meant: Creating directories are just extra steps so Pharo and its images keep the good practice to not let them pollute your home directory... as most programs do these days.

Re: [Pharo-users] ZnUrls with Non-ASCII characters

by PBKResearch

Sean The trick is to url encode the bit that contains the accented characters. In your case, try: ('https://en.wiktionary.org/wiki/','prÃªt#French' urlEncoded ) asUrl If you use urlEncoded on the whole string, the encoded slashes seem to confuse things.

reloading ffi library

by Steven Costiou

Hi, noob question: i installed bloc and tried to run examples. It worked well on Fedora 27 but not on latest Debian 64 bits because the path of libcairo.so.2 was wrong. So i fixed it in the code, but when trying the bloc examples again the lib path is still wrong (in the debugger). Is there a way to reload the cairo lib or to reset it, so that the path would be right and it would find the lib ? Steven.

Yes. Creating directories are just extra steps so Pharo and its images is just a good practice to not let it pollute your home directory... as most programs do these days.
