[Pharo-project] What are you using to write reports?
by Friedrich Dominicus Sept. 1, 2010

Sept. 1, 2010

I'm working slowly through Seaside, Aida, Pharo etc. I just wonder what you are using to make "usable" reports. (Be it in electronical form or printed). A related question, how does you interface e.g to let's say OpenOffice or maybe MS Office? Thanks for suggestions.

[Pharo-project] Problems in loading GLORP
by Alberto Bacchelli Sept. 1, 2010

Sept. 1, 2010

Hi, By following both Sven's and Mariano's suggestions (I am referencing see this thread [1]), I am trying to load GLORP in Pharo. (On a MacOSX 10.6.4, I didn't tried on other machines). However, I am not able to complete the loading process. I tried with both a fresh Pharo image [2] and a Moose development one. I tried both by using the metacello instructions in SqueakDBX [3], and by using Sven's script [4]. In any configuration, when it loads GLORP, the loading process freezes in "Compiling methods". For example, by using Sven's script, I am able to run the first three statements, but the fourth freezes everything: (1) Scanner allowUnderscoreAsAssignment: true. (2) Gofer new squeaksource: 'PostgresV2'; package: 'PostgresV2'; load. (3) Scanner allowUnderscoreAsAssignment: false. (4) Gofer new squeaksource: 'SqueakDBX'; package: 'Glorp'; load. Similarly, it freezes following the metacello instructions in the SqueakDBX site. Could you please tell me how you are able to load GLORP? Thank you. Cheers, Alberto [1] http://lists.gforge.inria.fr/pipermail/pharo-project/2010-June/028664.html [2] http://www.pharo-project.org/pharo-download/stable [3] http://squeakdbx.org/Installation [4] http://www.squeaksource.com/ADayAtTheBeach/GlorpPostgreSQLPharoLoader-SvenV…

Hi guys, Given any Pharo image and a (any) package or class category, how do you find if the package/class category belongs to the official image release? Thanks, HernÃ¡n

Re: [Pharo-project] What are you using to write reports? Lyx!

I posted this earlier but never saw it show up. Apologies if it was posted but I didn't see it. > Tab-delimited text is very useful; I tend to see the world in terms of R (http://cran.r-project.org/) data frames, even when I do not > plan to involve R. HTML makes a nice way to scroll through data. As for connecting with OpenOffice or (I can't say it<g>), I find > LaTeX to be much nicer to use. It has a steep learning curve, but the view from near the top is pretty good. If you find LaTex has a steep learning curve I suggest you give Lyx a try. I write everything in either vi or Lyx. I use Linux but Lyx can also be found on Windows and Mac. By the way, when I write the external documentation (using Lyx of course) for Squeak/Pharo packages that I write where do I put this documentation?

[Pharo-project] Image file format ?
by James Ladd Sept. 1, 2010

Sept. 1, 2010

Hi All, I'm looking for information on the image file format, something that tells me the layout. A little like this: +--------+ ! version ! +--------+ ! count ! +--------+ etc. I can glean this information from the Squeak C sources but I'm wanting some additional information for validation. Maybe it is in the blue book but I have also read that Squeak varies on this a little. Also - what is a Compact Class Array section of the image file? Rgs, James.

[Pharo-project] float printing
by stephane ducasse Sept. 1, 2010

Sept. 1, 2010

hi guys here is a point where squeak and pharo could sync. Now I propose the change to be applied in Pharo. http://code.google.com/p/pharo/issues/detail?id=2888 in essence 0.1+0.2=0.3 which is normal since (0.1+0.2) hex '3FD3333333333334' 0.3 hex '3FD3333333333333' showing that we are in presence of two difference numbers. So since floats are approximations anyway, I like the idea that the language tells me all the time. This fits perfectly with the discussion and actions we got last year on floats. Of course 0.1s2 + 0.2s2 = 0.3s2 is true storeString is already conveying the right information both in squeak and pharo (0.1+0.2) storeString '0.30000000000000004' 0.3 storeString '0.3' I suggest that printString on float ie on little change in printString. So talk now. My point is that since we cannot perfectly lie better say it. I think that GNU and python are right so this an easy fix with a really good impact on education. Stef printOn: aStream base: base "Handle sign, zero, and NaNs; all other values passed to absPrintOn:base:" self isNaN ifTrue: [aStream nextPutAll: 'NaN'. ^ self]. "check for NaN before sign" self > 0.0 ifTrue: [self absPrintExactlyOn: aStream base: base] ifFalse: [self sign = -1 ifTrue: [aStream nextPutAll: '-']. self = 0.0 ifTrue: [aStream nextPutAll: '0.0'. ^ self] ifFalse: [self negated absPrintOn: aStream base: base]]
