In a fresh 60437 image, in Playground evaluating...
Metacello new
configuration: 'ICal';
repository: 'github://codeZeilen/ical-smalltalk:master/repository';
onConflict: [:ex | ex allow];
load.
==> Could not resolve: ICal-Core [ICal-Core-PaulDeBruicker.5] in
/home/ben/.local/share/Pharo/images/60437-01/pharo-local/package-cache
http://squeaksource.com/ical ERROR: 'GoferRepositoryError: Could not access

In a new fresh 60437 Image (i.e. empty package-cache)
World menu > Monticello > +Repository > squeaksource.com...
MCSqueaksourceRepository
location: 'http://squeaksource.com/ical'
user: ''
password: ''
==> open repository then errors "MCRepositoryError: Could not access
http://squeaksource.com/ical: ZnInvalidUTF8: Illegal continuation byte for
utf-8 encoding"
In Chrome, opening http://www.squeaksource.com/ical
then clicking <Versions>
and the browser's View Page Source,
I see...
<?xml version="1.0" encoding="iso-8859-1"?>
Googling: zinc iso-8859-1
finds...
http://forum.world.st/Problem-using-Zinc-in-Pharo-4-Moose-5-1-td4825329.html
but "ZnByteEncoder iso88591"
errors with "KeyNotFound: key 'iso88591' not found in Dictionary"
and inspecting "ZnByteEncoder byteTextConverters keys sorted"
confirms this key is missing (@Sven, I'm curious why was this removed? )
Now https://en.wikipedia.org/wiki/ISO/IEC_8859-1
indicates IBM819 is an alias
and " ZnByteEncoder newForEncoding: 'ibm819' "
works okay
So in MCHttpRepository>>#loadAllFileNames
changing...
queryAt: 'C' put: 'M;O=D' ;
get.
to...
queryAt: 'C' put: 'M;O=D' .
ZnDefaultCharacterEncoder
value: (ZnByteEncoder newForEncoding: 'ibm819')
during: [client get].
Then from Monticello opening the previously defined
http://squeaksource.com/ical
works!!
Now I was hoping that reverting #loadAllFileNames
and in Playground doing...
converters := ZnByteEncoder byteTextConverters.
converters at: 'iso-8859-1' put: (converters at: 'ibm819').
might alleviate the problem, but no luck.
Anyone know a better way to deal with this that hardcoding the encoding
into #loadAllFileNames?
