RE: Does anyone else have this pattern?

I like this sort of pattern, but I wouldn't put it in the stock image. I would make it an extension of whatever project uses it (i.e. it might be in Collection but under the protocol *Your-Project-Name), or maybe make a new project called "Collection extension" or something.> Date: Fri, 29 Jun 2007 15:56:26 +0100> From: pdcawley(a)bofh.org.uk> To: squeak-dev(a)lists.squeakfoundation.org> Subject: Does anyone else have this pattern?> > During my SmallLint directed exploration of the guts of the> OmniBrowser, I came across a chunk of code that looked (very> approximately like)> > coll := self buildCollection.> > coll ifEmpty: [^ self].> coll size = 1 ifTrue: [self browse: coll first].> self askUserToChooseFrom: coll.> > Now, call me Mr Fussy, but I really don't like seeing function scoped> temporaries if I can help it, so it seems to me that one could write a> method on Collection along the lines of:> > ifEmpty: emptyBlock ifSingular: singularBlock otherwise: otherwiseBlock> > self ifEmpty [^ emptyBlock value].> ^self size = 1> ifTrue: [singularBlock valueWithPossibleArgument: self first]> ifFalse: [otherwiseBlock valueWithPossibleArgument: self]> > Which would clean the original method up like so:> > self buildCollection> ifEmpty: []> ifSingular: [:node| self browse: node]> otherwise: [:coll| self askUserToChooseFrom: col]> > Which, to my eyes at least, seems to express the intent more clearly.> > The obvious rearrangements and subsets spring to mind, along with> otherwiseDo:, otherwiseInject:, otherwiseCollect:> > So, am I alone in thinking something like this would be useful, and if> I'm not, what's the best way to go about getting it into the image?> Create a CollectionTesting package and add it to the dependencies of> any packages that use it?

Parsing Smalltalk with SmaCC
by Bergel, Alexandre 29 Jun '07

29 Jun '07

Dear SmaCC friends, I wish to adjust a smalltalk parser. However, I was not able to find a SmaCC description that actually works. Just try to install SmaCCDev-lr.17 in a squeak-dev image (that already contains SmaCC-lr.13). Open the SmaCC window, load StScanner and StParser. And try to test: 1 + 2. A message not understood: StScanner>>id is raised. any idea ? By the way, I was surprise to see that RBParser is not SmaCC-based...

Does anyone else have this pattern?
by Piers Cawley 29 Jun '07

29 Jun '07

During my SmallLint directed exploration of the guts of the OmniBrowser, I came across a chunk of code that looked (very approximately like) coll := self buildCollection. coll ifEmpty: [^ self]. coll size = 1 ifTrue: [self browse: coll first]. self askUserToChooseFrom: coll. Now, call me Mr Fussy, but I really don't like seeing function scoped temporaries if I can help it, so it seems to me that one could write a method on Collection along the lines of: ifEmpty: emptyBlock ifSingular: singularBlock otherwise: otherwiseBlock self ifEmpty [^ emptyBlock value]. ^self size = 1 ifTrue: [singularBlock valueWithPossibleArgument: self first] ifFalse: [otherwiseBlock valueWithPossibleArgument: self] Which would clean the original method up like so: self buildCollection ifEmpty: [] ifSingular: [:node| self browse: node] otherwise: [:coll| self askUserToChooseFrom: col] Which, to my eyes at least, seems to express the intent more clearly. The obvious rearrangements and subsets spring to mind, along with otherwiseDo:, otherwiseInject:, otherwiseCollect: So, am I alone in thinking something like this would be useful, and if I'm not, what's the best way to go about getting it into the image? Create a CollectionTesting package and add it to the dependencies of any packages that use it? Submit a changeset somewhere? And enquiring mind wants to know. Thanks in advance for your consideration.

Omnibroser - DuoBrowser - What is the equivalent of OBActor ?
by Cédrick Béler 29 Jun '07

29 Jun '07

Hi, I'm still looking at omnibrowser, and loaded DuoBrowser of Roel. Still working but got an error becasue it uses OBNodeActor and al. It seems this actors classes have been removed. What was their role ? and what is the alternative way of doing now ? Thanks, Cédrick

Paying for projects
by J J 29 Jun '07

29 Jun '07

Hi all,As you have probably seen, I see a lot of things I want to see done in Smalltalk, but I don't have time to do any of it. My "eyes are bigger then my stomach" as it were. So it occurred to me today that a possible solution to this problem would be to simply pay to have some of the work done.So to that end, I would like anyone who would be interested to let me know. I will set up a mailing list for any people would want to be take (or give) projects. I will suggest my project on the list, you can answer me privately (or publicly) with your bids. I will select someone, and publicly announce that it has been filled. After that it depends; we can talk publicly over the list, or use an intermediate like rentacoder [1] to ensure that both sides are safe. That is, I don't want to pay if I can't use the finished product, nor do I want the person doing the work to fear that they may get nothing for it.We can negotiate the different things, time frames, price, features. I mostly only be doing smallish projects. The payouts would probably be on the order of $50 - $100 USD but the projects should be small (and often) as well. And if this catches on, there could be much bigger projects or people may chip in to sweeten some of the more interesting pots.Some people have expressed concerns about bounties in the past that people might have their feelings hurt if they don't get picked. So I would just like to point out, this has nothing to do with the board or anything else. This is just something I wanted to do. I will choose the person the same way any worker is chosen for a given, i.e. the best fit/price/availability/reputation.The payout will work in the same way it's done on rentacoder: We have a bid off for who will do the job, negotiate the parameters and pick the best overall fit, then you do the work, then when it's finished if I accept you are paid. If I don't accept you can try to bring it up to spec, decide to give up, or ask for an arbitration if you think you have met requirements. In the case of the rentacoder site, the payment money is deposited as soon as I accept a bidder so no one can "take their ball and go home".I'm a big experimenter so many of the projects may be that you get paid and then never hear anything more (because I decide I don't want to go that way after all). But hopefully the money can soften that blow a little. :)And lastly, I know Squeak is largely a gift community, and I don't want to upset that. I think it is good that people give things to the community (and I will most likely release everything I pay for). I don't want to create a situation where everyone expects to be paid for everything. This is simply a case that I have not managed to get anyone interested in my ideas by talking, I can't realize them myself (this decade anyway), so my last option is to pay.Thanks,Jason[1] The advantage of using rentacoder as an intermediate is that it's established, and everyone will see the projects so it will be more smalltalk exposure. _________________________________________________________________ Live Earth is coming.

What to believe?
by Piers Cawley 29 Jun '07

29 Jun '07

What is a young Smalltalker to do? SmallLint forcefully suggests that: ^ Preferences optionalButtons ifTrue: [OBFixedButtonPanel new] should be rewritten as: ^ Preferences optionalButtons ifTrue: [OBFixedButtonPanel new] ifFalse: [nil] which would be fine, but as soon as I try and pretty print the rejigged method, it reverts to the version without the ifFalse: clause? Two tools enter, one tool leaves. But which one?
