[Pharo-project] Questions: PDFs, MySQL, TableMorph, seaside...
by Cameron Sanders May 12, 2009

May 12, 2009

What are my options for generating PDF output? In particular I want to minimize 3rd party library needs. Also, what about MySQL: is there a way to communicate with an external MySQL db without needing to install a 3rd party library? And If not, what is the most portable library? (And if I must use ODBC or something, on a Mac or Windows, how can I configure it from within Pharo?) I noticed that the panes in a TableMorph are not set to scroll together by default, is there an easy switch to make them scroll together? If I wanted to show an spreadsheet like display, is TableMorph the best starting point, or are there better higher-level tools (available in Pharo) worth learning? Finally, I *may* want to generate HTML output... so ... where is the best place to start getting oriented with seaside tools? Thanks in advance, Cam

[Pharo-project] Alien question
by StÃ©phane Ducasse May 12, 2009

May 12, 2009

Hi I'm trying to make sure that we can load Alien in Pharo. I'm moving some examples out of Alien-Core. Now I have some questions: - are these DynSuperSend #LdOuter #LdExplicitOuter class variable needed? - then we get a problem because the addition of classVariables should be done before parsing so I will move that to the preLoadingPackage. Stef initialize "ParseNode initialize. VariableNode initialize" #(#DynSuperSend #LdOuter #LdExplicitOuter) do: [:c | [self addClassVarName: c] ifError: []]. DynSuperSend := 126. LdInstType := 1. LdTempType := 2. LdLitType := 3. LdLitIndType := 4. SendType := 5. CodeBases := #(0 16 32 64 208 ). CodeLimits := #(16 16 32 32 16 ). LdSelf := 112. LdTrue := 113. LdFalse := 114. LdNil := 115. LdMinus1 := 116. LdOuter := 127. LdExplicitOuter := 139. LoadLong := 128. Store := 129. StorePop := 130. ShortStoP := 96. SendLong := 131. DblExtDoAll := 132. SendLong2 := 134. LdSuper := 133. Pop := 135. Dup := 136. LdThisContext := 137. EndMethod := 124. EndRemote := 125. Jmp := 144. Bfp := 152. JmpLimit := 8. JmpLong := 164. "code for jmp 0" BtpLong := 168. SendPlus := 176. Send := 208. SendLimit := 16

[Pharo-project] Alien

>We are trying to package it to load in the latest pharo. Good - but whats the state of support for the major platforms? (AFAIK John had it working on Mac). For instance on Windows a good pharo foreign interface is crucial for commercial value (accessing Win32API/COM/.NET/third party). Whats the plan regarding Alien? Intended for the 1.0 release or later? Loadable package or included within the standard image? Will it be a merge of FFI and Alien, or is Alien good enough?

Any new from the "Alien vs. FFI" front ;) Is Alien already available for various platforms like Win32? Thx Torsten -- Neu: GMX FreeDSL Komplettanschluss mit DSL 6.000 Flatrate + Telefonanschluss fÃ¼r nur 17,95 Euro/mtl.!* http://dslspecial.gmx.de/freedsl-surfflat/?ac=OM.AD.PD003K11308T4569a

[Pharo-project] Wiresong and OB

Looks like wiresong.ca is not responding (or is it only me). Why not move OB project code to squeaksource - this would also allow for easy browsing the code using the webbrowser ...

[Pharo-project] Long delay after loading 10301+10302

My image got unresponsive for a long time just at the end of load, showing the dialog 2 new update file(s) processed Attaching gdb to the process and call printAllStacks() gave me: 2033300892 WeakIdentityKeyDictionary>scanForNil: 2033132772 WeakKeyDictionary>rehash 2033128872 WeakKeyDictionary>finalizeValues 2033128780 >finalizationProcess 2033128688 SequenceableCollection>do: 2033128580 >finalizationProcess 2033128488 Semaphore>critical:ifError: 2033128396 BlockClosure>on:do: 2033128284 BlockClosure>ifError: 2033128152 Semaphore>critical:ifError: 2033128060 Semaphore>critical: 2033127968 BlockClosure>ensure: 2033127820 Semaphore>critical: 2033127684 Semaphore>critical:ifError: 2017849452 >finalizationProcess 2017849360 >restartFinalizationProcess 2017849544 BlockClosure>newProcess And this loop did last very long... Of course, this is a high priority process, so pressing ALT+. won't give me much feedback. Hmm, a high priority process taking CPU for a long time, that smells...

No, the intent is preserve the images as they are shipped see http://www.mobilewikiserver.com/ST80Docs.html & http://www.mobilewikiserver.com/SqueakDocs.html However if you have a script that removals all the *extra* things that people could run for server images that would be helpful at least to me, I realize that most folks don't care about 8MB, but on tiny devices that 8MB is golden...

So Float nan isLiteral should answer false. Note that there are still literal representation of Float infinity, like 1.0e1000. However, since Float infinity is not able to print literaly, and isLiteral is intended for print, this fix will answer false for infinite Floats too. Tx nicolas! Stef
