Re: [Pharo-users] Interval form: x to: y when x > y - or how to count down...

Of the couple of hundred programming languages I have used, there is precisely one that does what you expect (the S programming language, as implemented in R). And it is a major pain in the posterior with no upside that I can discern. Suppose I want a sequence of n consecutive integers beginning

Re: [Pharo-users] Interval form: x to: y when x > y - or how to count down...

Hi Richard - but why would you expect 1 to: 0 to give you an empty sequence? If I inspect “0 to: 1” I see: 1 -> 0 2 -> 1 So I would expect “1 to: 0” to see: 1 -> 1 2 -> 0. I asked for a sequence going from 1 down to 0 (in my mind). Knowing about all the by: -1 stuff seems very C’ish. Of

Re: [Pharo-users] How to write out simple Json?

Hi Sven - is there no convenience shortcut we can use in our code to make this less wordy when we are specifying it? E.g. the following is very convenient to write - but doesn’t work (as you have $‘ and not $“ ) ex := { 'track'-> 'pharo'. 'language' -> 'smalltalk'.

I like that http://www.bagelconcertfinder.com uses Seaside and also my Twitter Bootstrap Library. Thanks so much for your library! I have built several applications in seaside, and always dig using it.. it’s my go to framework when I do a project on my own.. Seaside by default works with

Re: [Pharo-users] How to write out simple Json?

I really don't understand. JSON needs Dictionaries and Arrays (or other Sequenceable Collections). That has nothing to do with Pharo or how NeoJSON or STONJSON are implemented - it is what defines JSON. Of course, compatible objects work as well (NeoJSONObject is an example). You could make

Re: [Pharo-users] Interval form: x to: y when x > y - or how to count down...

I would expect 1:0 to give me an empty sequence because (a) for all other natural numbers n, 1:n gives me a sequence of n numbers, and (b) how else am I supposed to get an empty sequence? Under your interpretation, (x to: y) would never be empty. This has absolutely nothing to do with C. As I

Re: [Pharo-users] Repeateble URLs - REST?

I fully agree with everything Torsten said, but I would like to add a couple of points. It is very easy to add a couple of readable/shareable URL to a classic Seaside app. Here is a simple example: https://audio359.eu/ss/audio359-store?showSKU=sku0101 This jumps right into a web store written

Re: [Pharo-users] How to write out simple Json?

Just to add more flavour to this - it seems quite wordy that we have to do this (or equivalent) to write some config. ex := OrderedDictionary new at: 'track' put: 'pharo'; at: 'language' put: 'smalltalk'; at: 'exercises' put: ( OrderedDictionary new

Re: [Pharo-users] How to write out simple Json?

1. A JSON "object" corresponds to some kind of dictionary in Smalltalk. 2. {#a -> 1. #b -> 2} is NOT A DICTIONARY. It is an Array of Associations. 3. {#a -> 1. #b -> 2} asDictionary *is* a dictionary. 4. My Smalltalk allows #{#a -> 1. #b -> 2} -- how could I let it be less

[Pharo-users] How to write out simple Json?

I am stumped about how to write out some simple json (for a config file). I didn't think I need Neo, and STONJSON would be fine but it seems like creating items like: { 'id'-> self id. 'name' -> self name } gives an error about the association. I think you have to do: { ('id'-> self id)
