Re: [Pharo-dev] [Pharo-users] Call about Numerical Methods in Pharo :)

by Alexandre Bergel

Hi ! > - Do a public call to know what is missing for you: this is this mail :) > Didier would like to work on concrete cases. I love that attitude > So tell us :) This is an excellent initiative! I personally need the following: - Shapiro-Wilk test to check for data normality - Kruskal-Wallis to analyze differences in median values between samples - Bonferroni-Dunn to support multiple comparison and controlling the group error rate - Mann-Whitney U test is a nonparametric statistical test that operates over two samples of the same size.

Re: [Pharo-dev] TextConverter is broken

by Henrik Sperre Johansen

Not sure I'd say Squeak's (5.0 at least) MacRoman conversion is free of bugs either, at least the "legacy" ByteTextConverter subclass in Pharo passes the following: "U+0152, Latin capital ligature OE is codepoint 16rCE in mac-roman" ((Character value: 16r0152) asString convertToEncoding: 'mac-roman') first charCode = 16rCE. "Codepoint 170 in MacRoman is TM sign, U+2122" ((Character value: 170) asString convertFromEncoding: 'mac-roman') first charCode = 16r2122.

If, by, "modern", we mean 1.4 onwards... (The ByteTextConverter tables *were* updated it seems, so just MacRomanTextConverter initializeLatin1MapAndEncodings. (Character value: 216) asString convertToEncoding: 'mac-roman' should yield correct results) Cheers, Henry -- View this message in context: http://forum.world.st/TextConverter-is-broken-tp4882039p4882087.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Re: [Pharo-dev] TextConverter is broken

by Henrik Sperre Johansen

There was a bug in the old byteToUnicodeSpec tables (missing 2's in some of the latter entries, one of which should have been 16e02D8). So initializeLatin1MapAndEncodings erroneously picked that over the correct D8. In a modern image, Sven has fixed the byteToUnicodeSpec (They're parsed directly from the Unicode site, so at least the hope is they are correct, at least), but the cache tables have not been updates, one can do this by executing: ByteTextConverter initialize. ByteTextConverter allSubclassesDo: [:each | each initializeLatin1MapAndEncodings].

Re: [Pharo-dev] Mocking networkâ¦

I assume the mock object does not exercise any real network code or primitives.

This means that when you run a test your network requests are handled by a mock object and you can tell it that for this URI it should give you this response.
