Re: How to port VW code to Pharo?

by stephane ducasse

Hi Aik-Siong - Check the archives of this mailing-list because people discussed it. - Do you have tests because it can really help you? The tests in Moose really helped me when I migrated Moose from VW to Pharo. - you may have some differences with float precision. - Some people such as Christian Haidler or Pavel Krivanek did some exporting tools from VW. In the past, I published on store a file format for Squeak (and you should patch the assignment because pharo does not support _) - You may have some issues with namespaces but if you did not use private import you can just map a namespace to a class prefix. - I suggest that you build a baseline as soon as you start to have a package. you commit on github you add GH actions running your tests there is an intensive documentation on baseline in the https://github.com/pharo-open-documentation/pharo-wiki - Will you port GF/ST too? - I have a limited amount of time but I could give you some hands. Now I do not have access to VW for years.

Hi, ask on the VW mailing list (or search the interwebs; currently can't remember what specific to search for besides: porting pharo visualworks namespaces), someone was boasting pretty complete exporter, capable of "de-namespacing", among other things. It was used to port some other sizeable project to Pharo, AFAIR. Sorry, that's all I have. ________________________________ From: Aik-Siong Koh <askoh(a)askoh.com> Sent: Wednesday, August 2, 2023 7:29:48 PM To: Pharo Development List Subject: [Pharo-dev] How to port VW code to Pharo?

and woot: I'm a good parser (bullshit eliminator; went for a few of the examples - after you hinted it is super-permissive), but there is no reason for the default to be that tolerant. perhaps an introduction of "culture" fo the default parsing, and otherwise some format rules ? ________________________________ From: RauÅ¡ Miloslav Sent: Wednesday, July 19, 2023 6:50:13 PM To: Pharo Development List Subject: Re: [Pharo-dev] Fun with dates Right of the bat: mind blown (they probably translate to something) ________________________________ From: Guillermo Polito <guillermopolito(a)gmail.com> Sent: Wednesday, July 19, 2023 6:48 PM To: Pharo Development List Subject: [Pharo-dev] Fun with dates Try to guess what each of the following lines of code do: '''/5%9/$#=7*''*(?&&)58-,=93/1(0 1&<"1%?#$-::#)' asDate.

Re: Fun with dates

by James Foster

Not that this isnât fun, but whenever anyone says âgues what it does," it reminds me of one of my favoriate quotes from Dijkstra in his 1972 ACM Turing Award Lecture, âThe Humble Programmerâ: The competent programmer is fully aware of the strictly limited size of his own skull; therefore he approaches the programming task in full humility, and among other things he avoids clever tricks like the plague. In the case of a well-known conversational programming language I have been told from various sides that as soon as a programming community is equipped with a terminal for it, a specific phenomenon occurs that even has a well-established name: it is called âthe one-linersâ. It takes one of two different forms: one programmer places a one-line program on the desk of another and either he proudly tells what it does and adds the question âCan you code this in less symbols?â âas if this were of any conceptual relevance!â or he just asks âGuess what it does!â. From this observation we must conclude that this language as a tool is an open invitation for clever tricks; and while exactly this may be the explanation for some of its appeal, viz. to those who like to show how clever they are, I am sorry, but I must regard this as one of the most damning things that can be said about a programming language. â https://www.cs.utexas.edu/~EWD/transcriptions/EWD03xx/EWD340.html > On Jul 19, 2023, at 9:48 AM, Guillermo Polito <guillermopolito(a)gmail.com> wrote: > > Try to guess what each of the following lines of code do: > > '''/5%9/$#=7*''*(?&&)58-,=93/1(0 1&<"1%?#$-::#)' asDate. > > '*%!(a)$4*4#!$!.&0-";)7.<7?%(; $535(0536.%#56&++''3!%0/' asDate. > > '/-@+%3:3.''9"04=. @5+$;"& (6.-,?@*6"?43@@>*>:' asDate. > > '1(%&0:19)) 7-?1.8;=?8+!&42-(?#>357).!=21603* 6=?38.1**,//'':@663>.09!2%=!%%%2!>4'':@#/8!@==2>%651)</' asDate. > > ',$*3,3''="0+0>:#14-8+(1@$&827%6-!)9-<>:"2+>&*39 !"(27' asDate. > > '''"?. <>!@"2(%7#)0 )46+#'';=+"94?%)9 +!<.+!9,2*5("9$11-,?49 =6*77. 0;/''%%/*' asDate. > > '4.+@)3&11)."+.6=$&$0>5:5;:$,%5-+,4$0>")>4838''*2/' asDate. > > '!7$:''!@0=)?0?<#&@*./0.:&?$?4 =<!><(7)@3$!:"$%%=""/?4*4=0?*$).,<+& ::"8>:925$8!,2,95' asDate. > > ' &+?!$3"(<*)1");35 $:&<"$!' asDate. > > '>6(# %2736:-1#@@9%9''+"#?37''2,<3>8-*5"$2-6#''365++*8 &' asDate. > > '?(2/=-@=@:4?/(3$3(8"&,!-2/&6&&' asDate. > > '&?7+=''9,:$(430,3#/$4#866'';2/*,?):. -!#"7=?6:$3"5 -$/=0' asDate. > > '3-;;=72@,9=%*.;+)74@7") -&?(''7+!3-3<-0,<8:(,,;+5-$:81#&6''7830;"01+@>7<37''!(#/9"6%0?' asDate. > > ';";5!9!,4/;25!0(<$4)''2"(2&-''4/>/.'')99(>><' asDate. > > '03="9-/,*(;74"%@>=''91%>#=*=6*0/#02@?)0.' asDate > > > G
