Did we integrate #assert:equals: in trunk ? If not, I think we should. Thanks tonyg, could you add an explicit description, like assert:...equals:...description: 'RFC822 forbids non-integer seconds in dates' (if the selector exists, if not, we should put this sentence in a comment) Nicolas 2011/9/12 <commits(a)source.squeak.org>: > A new version of NetworkTests was added to project The Inbox: > http://source.squeak.org/inbox/NetworkTests-tonyg.24.mcz > > ==================== Summary ==================== > > Name: NetworkTests-tonyg.24 > Author: tonyg > Time: 12 September 2011, 9:31:08.83 am > UUID: 601d24e1-1caa-4e24-a466-97730972c0e0 > Ancestors: NetworkTests-ar.23 > > Test case for Network-tonyg.119, which avoids printing fractional seconds into an email "Date:" header, since the RFC forbids non-integer seconds in dates. > > =============== Diff against NetworkTests-ar.23 =============== > > Item was added: > + TestCase subclass: #MailMessageTest > + instanceVariableNames: '' > + classVariableNames: '' > + poolDictionaries: '' > + category: 'NetworkTests-RFC822'! > + > + !MailMessageTest commentStamp: 'tonyg 9/12/2011 09:17' prior: 0! > + This is the unit test for the class MailMessage.! > > Item was added: > + ----- Method: MailMessageTest>>testDateStampFractionalSecondFormatting (in category 'as yet unclassified') ----- > + testDateStampFractionalSecondFormatting > + self assert: (MailMessage dateStamp: (DateAndTime fromSeconds: 1.234)) > + equals: 'Tue, 1 Jan 1901 00:00:01'! > > >

Any chance of getting a reject/OK on the below? Bert had an issue with the original - Monticello-fbs.467 - which 468 addresses (namely, a misleading variable name). frank On 9 June 2011 20:10, <commits(a)source.squeak.org> wrote: > A new version of Monticello was added to project The Inbox: > http://source.squeak.org/inbox/Monticello-fbs.468.mcz > > ==================== Summary ==================== > > Name: Monticello-fbs.468 > Author: fbs > Time: 9 June 2011, 8:10:14.668 pm > UUID: adb87d13-5e2c-4032-b404-f26c78e21f4a > Ancestors: Monticello-ul.466 > > Better error messages for off-line work: > * If you can't find a base "full version", say so > * If you Give Up on trying to resolve a name, report the actual failure rather than trying to access a socket anyway, and throwing a primitive failed error. > > =============== Diff against Monticello-ul.466 =============== > > Item was changed: > ----- Method: MCDiffyVersion>>baseSnapshot (in category 'as yet unclassified') ----- > baseSnapshot > + | baseVersion | > + baseVersion := self workingCopy repositoryGroup versionWithInfo: base. > + baseVersion ifNil: [Error signal: 'Missing snapshot: ', self baseInfo name]. > + ^ baseVersion snapshot! > - ^ (self workingCopy repositoryGroup versionWithInfo: base) snapshot! > > Item was changed: > ----- Method: MCHttpRepository>>allFileNames (in category 'required') ----- > allFileNames > | index | > + [self displayProgress: 'Updating ', self description during:[ > - self displayProgress: 'Updating ', self description during:[ > index := HTTPSocket httpGet: self locationWithTrailingSlash, '?C=M;O=D' args: nil user: self user passwd: self password. > + ]] on: NetworkError do: [ :e | self error: 'Could not access ', location, '(', e className, ')']. > - ]. > index isString ifTrue: [self error: 'Could not access ', location]. > ^ self parseFileNamesFromStream: index ! > > >

A Vision For Smalltalk
by Overcomer Man 12 Sep '11

12 Sep '11

In my quest to install a Video application discovered in Squeak's Universe browser into Cuis, I asked for help and received three critical pieces of information. The fact .mcz files are .zip files which need renamed to see what's inside. The location of the FFI library, invisible from the main Squeak webpage. And the packages within FFI to fileIn and in what order. The FFI works but the video application is still not fully installed, due to another unknown bug. Along the way I noticed the .mcz files contained a lot of other junk besides Smalltalk code, and all the code for several FFI sub-projects is under the same filename inside the different packages. Using .mcz instead of .zip is unnecessary complexity. The extra packaged files are not Smalltalk. Why not just use Smalltalk? This reminds me of a job experience where the boss insisted I use a new GUI-builder to add some features to Hot-Draw. I knew Smalltalk, not the language of the new GUI-builder. So I worked with the inspector and discovered the code needed to accomplish the job and did it in Smalltalk. The boss didn't realize the GUI-builder was a language divergence from Smalltalk and work done with it was not maintainable. It's obvious the Universe brower is passe'. Do we really need the Monticello browser or half the other tools? Cuis frees programmers from a lot that isn't Smalltalk. People will do what they want but I suspect some forks, even Pharo, could be collapsed into Cuis. We need to focus on Smalltalk and developing user friendly applications with it. Building tools that obscure Smalltalk may lead to unmaintainability. The job of tools is to do real work for the end user. Occasionally a new tool is needed but constantly working on the toolbox is usually unnecessary. Keep It Simply Smalltalk.

Re: [squeak-dev] Simple math editor/typesetter

I use Lyx on top of LaTeX, then export to image which can be imported into Squeak. All very manual. I recall seeing where someone was piping through LaTeX to do the job on the fly. I should think that would produce a print file easily, a bit harder to make a little illustration for on-screen, interactive use.

Is there any existing work that I might be able to re-use/build upon? For instance, given this equation, (1+2/3)*4 I would like to see it displayed like the Equation Editor in Microsoft Word or the equations in a Mathematica notebook. See attached screenshots: http://forum.world.st/file/n3805256/word.png http://forum.world.st/file/n3805256/mathematica.png I'm not looking for anything fancy. Something simple to get me started would be helpful as well. I looked briefly at Dr. Geo but I don't think it supports displaying equations in that manner.
