Howdy!
(cc to squeak-dev because I think lots want to read this) If you want to know some cool history of Smalltalk, and perhaps this is a strong argument in actually *being* a Smalltalk and not trying to distance yourself from that rich and lovely heritage.... anyway, here goes: On 04/28/2014 08:14 PM, Alain Busser wrote: > Also, Ruby is famous for these methods: > > *select > *reject > *collect > > do these names not remind you something ;-) ? There is a funny story about these verbs. Martin McClure told me at ESUG in Brest to ask Dan Ingalls about it, hinting that they are "inspired" by a famous song. And thus I did ask Dan in my interview with him I did a few years back over Skype (it is an interesting interview, for example - was there an inspiration from biology when Smalltalk was created?): http://files.krampe.se/interview.mp3 ...the song in question is by Arlo Guthrie: http://en.wikipedia.org/wiki/Alice%27s_Restaurant_Massacree ...and here is a URL to the lyrics of it: http://www.lyricsty.com/arlo-guthrie-alices-restaurant-lyrics.html (search down to "injected"!) ...or just let me quote: "They got a building down New York City, it's called Whitehall Street, Where you walk in, you get injected, inspected, detected, infected, Neglected and selected. I went down to get my physical examination one Day, and I walked in, I sat down, got good and drunk the night before, so I looked and felt my best when I went in that morning." ...now... where do we stuff in #neglect:? :) regards, Göran |

Thanks Göran, that's great!
I'm really looking forward to seeing an implementation of Collection>>neglect:, I can't believe nobody thought of this before ;-) Dave > Howdy! > > (cc to squeak-dev because I think lots want to read this) > > If you want to know some cool history of Smalltalk, and perhaps this is > a strong argument in actually *being* a Smalltalk and not trying to > distance yourself from that rich and lovely heritage.... anyway, here > goes: > > On 04/28/2014 08:14 PM, Alain Busser wrote: >> Also, Ruby is famous for these methods: >> >> *select >> *reject >> *collect >> >> do these names not remind you something ;-) ? > > There is a funny story about these verbs.

I like it. Personally was thinking that neglect could work similar to reject but instead return a wrapper using the first collection as a "backend". So it uses the same collection but "neglects" those elements not matching :) Dynamically add some nasty Trait? regards, Göran |
The influence of Smalltalk on Ruby is well known, and is in fact how I found you people:)
Particularly striking is Ruby's block/closure syntax. Looks almost the same, which sticks out like a sore thumb in a dot and curly language. In the most recent versions I think they've even added keyword messages. Awesome to know where #collect: came from. I wondered about that; given that the guy running the LRG was fond of LISP, I would have expected it to be called #map:. I think the Ruby collections have #map() as a synonym for #collect(), reflecting the language's dual heritage. I've always used collect though because it makes me think of baseball cards! > On Apr 29, 2014, at 9:48 AM, Göran Krampe <[hidden email]> wrote: > >> On 04/29/2014 06:41 PM, tim Rowledge wrote: >> >>> On 29-04-2014, at 9:30 AM, Göran Krampe <[hidden email]> wrote: >>> >>> ...now... where do we stuff in #neglect:? :) >> >> Clearly, aCollection neglect: [:item| item size > myFoo] would return a WeakArray of elements matching the block criterion; then when nobody is paying much attention they can be garbage collected. > > I like it.

I went down to get my physical examination one day, and I walked in, I sat down, got good and drunk the night before, so I looked and felt my best when I went in that morning. `Cause I wanted to look like the all-American kid from New York City, man I wanted, I wanted to feel like the all-, I wanted to be the all American kid from New York, and I walked in, sat down, I was hung down, brung down, hung up, and all kinds o' mean nasty ugly things. And I waked in and sat down and they gave me a piece of paper, said, "Kid, see the psychiatrist, room 604."

Sure, but I swear I saw it before.

But it was Martin that gave me the idea to ask and clarify :) There are other things in that interview - like for example - did biology (the cell etc) actually serve as inspiration at that time? regards, Göran |
