DNU when accepting an empty string
by stepharo Dec. 7, 2015

Dec. 7, 2015

Hi if I select a method, and remove eveyrthing and press accept I get a DNU. I would like to fix that for newbies. https://pharo.fogbugz.com/f/cases/17205/DNU-when-accepting-an-empty-string I proposed one fix but I would love to have someone to have a look at it (I'm preparing the lectures for Yaounde and Lome and I'm sick :( Stef

Re: [Pharo-dev] [squeak-dev] Re: [Unicode] Class Unicode --> data from unicode.org
by H. Hirzel Dec. 7, 2015

Dec. 7, 2015

As the issue is about potential reuse of GNU Smalltalk code snippets / classes regarding Unicode the most straightforward thing is to ask Paolo Bonzini (http://smalltalk.gnu.org/blog/bonzinip) if he permits the reuse under an MIT license. So far no code has been identified which would be needed under an MIT license.

Quick debugging failed #assert:equals tests (Differ in comment)
by Torsten Bergmann Dec. 7, 2015

Dec. 7, 2015

Hi the #assert:equals method is often used in Test cases: we have 2491 senders in recent Pharo5.0 Latest update: #50487. Anytime I have to debug a failing test using it I find it hard to compare the expected and actual value when it is a string in the debugger panes. Pharo tools come to the rescue because we already have a differ inside the image. I would therefore propose to add the following comment into TAssertable>>#assert:equals: assert: actual equals: expected " DiffModel new showOptions: true; leftText: actual; rightText: expected; contextClass: nil; openWithSpec " ^ self assert: expected = actual description: [self comparingStringBetween: actual and: expected] With this additional comment one can quickly open the diff tool and check the differences in the expected vs. actual string. Directly by evaluating the commented expression in the debugger. What do you think? Should we add it? Are there any other solutions to quicly find the differences? Thanks T.

You can no longer stick your head in the sand and pretend that "plain" text is ASCII. There Ain't No Such Thing As Plain Text.

In fact, any string in Javascript is UTF-16 encoded. In fact, it's the only thing Javascript deals with. You cannot have a string in Javascript that is not UTF-16 encoded.

A String is a collection of Charactervalues. A Swift Character represents one perceived character (what a person thinks of as a single character, called a grapheme). Since Unicode often uses two or more code points(called a grapheme cluster) to form one perceived character, this implies that a Charactercan be composed of multiple Unicode scalar values if they form a single grapheme cluster. (Unicode scalar is the term for any Unicode code point except surrogate pair characters, which are used to encode UTF-16.) >> This change has the potential to prevent many common errors when dealing with string lengths or substrings. It is a huge difference to most other Unicode-aware string libraries (including NSString) where the building blocks of a string are usually UTF-16 code units or single Unicode scalars. cheers -ben

Re: [Pharo-dev] [Unicode] collation sequences (Re: [squeak-dev] Unicode Support)
by EuanM Dec. 7, 2015

Dec. 7, 2015

Hannes, The Unicode standard provide compatibility codepoints for compatibility purposes and prefers all characters to be represented composed form - as that way they are comparable and sortable. (Some composed characters have *more than one* compatibility codepoint. The canonical example is the composed character #(0041 030a) which can be represented by EITHER the compatibility codepoint #(00c5) "Latin Capital Letter A with Ring" above OR by #(212b) "Angstrom sign" ) On 7 December 2015 at 08:17, H.

Hi Hannes, It's looking like we should be able to conflate a bunch of existing facilities and code. The various Smalltalks seem to have approached Unicode like the old story of the blind men describing an elephant. There are lots of components when are usefully described and dealt with, and if we can just put them all together it'll will be less new work, and we should get a more portable outcome, and a more robust solution.
