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

by S Krish

This is fine: www.bagelconcertfinder.com/zipcodes/{zipCode} Preferred is : *https://......siteName.../boundedContext/resourceInPlural/{resourceId}* So this can be as you state but without _ underscores and "concertBlogging" is identified bounded context for a set of resources https://....siteName../*concertBlogging*/blogs/{blogId} Plurals are recommended. Lots of Style conformance is recommended, stick to REST and not use actions/ verbs in urls et als.. You can break many of the so called rules and still it will work fine for you, but its up to you, to decide what you adhere to and what you define for yourself https://restfulapi.net/resource-naming/ <https://restfulapi.net/resource-naming/> https://docs.microsoft.com/en-us/azure/architecture/best-practices/api-desi… Given the conflicting advices on REST, you can try and adhere to one-two sources of advice.

Repeateble URLs - REST?

by sergio ruiz

Hi, all.. I am looking to have a repeatable url so users can save them and share them.. something like: www.bagelconcertfinder.com/zipcode/44805 and in my next project, Iâll be doing something like a CMS where you would get: /blog_entries/this-is-the-path I am thinking of using REST to flesh out the paths.. does this seem reasonable? ---- peace, sergio photographer, journalist, visionary Public Key: http://bit.ly/29z9fG0 #BitMessage BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.codeandmusic.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Re: [Pharo-users] Can't <BlSpace> addChild: <BlSpartaMozCanvasBuilder>

by Tudor Girba

Hi, addChild: expects a BlElement not a canvas. A BlElement draws on a canvas object that is passed to it. SpartaCanvas is an abstract class. If you want to instantiate a canvas, pick one of the subclasses. For example, for MozCanvas, see MozExamples.

Re: [Pharo-users] What does the Package and Sub-Package comment do?

by Denis Kudriashov

Hi Tim. Behaviour is similar to Pharo 6. When class is selected the comment belongs to the class. If not then it belongs to the package. There is no such thing as a tag comment. I thought the default comment text is clear enough to avoid confusion. But probably it's not as you wrote this mail. So it is a room for improvements. Package comment is managed as a comment of ts manifest class. When you first time add it the manifest class is created. 25 ÑÐµÐ²Ñ. 2019 Ð³. 15:09 Ð¿Ð¾Ð»ÑÐ·Ð¾Ð²Ð°ÑÐµÐ»Ñ "Tim Mackinnon" <tim(a)testit.works> Ð½Ð°Ð¿Ð¸ÑÐ°Ð»: Anyone have any thoughts on this?

Re: [Pharo-users] Windows 64bit, long filename issue but after a second load, how to categorise and report this?

by Tim Mackinnon

Just to add some additional notes on this (and I will also file an issue, as I donât think one has been submitted, and I donât think this is fully down to file path length alone) - After some more testing, we have also seen the error on Windows 32bit as well (so while easier to get in 64bit, it does occur in 32bit like others have reported). My real concern however, is that a simple project (which admittedly pulls in a single Filetree prerequisite - PharoWebBrowser) seems to trigger this error - but confusingly references files that donât appear to be in the image. Tracing through PharoWebBrowser - there are some file tree based pre-reques and some that are mcz - and none of them have files like: testRaiseUnexpectedMessageWhenTooMuchMessages.st And this method is not in the image that gets loaded into OSX. So I am wondering where these long files are coming from? So yes, while there is a long filename issue - is there another hidden issue underneath all of this where files we arenât even using are getting reference somehow?

Re: [Pharo-users] JSON keys not quoted?

Not necessarily, but symmetry is important and a lack of symmetry is often a possible indication of trouble. Anyway, since the standard is crystal clear that JSON keys/names in objects must be strings, I am enforcing that now. It is not OK to silently generate illegal JSON. https://github.com/svenvc/NeoJSON/commit/c368bbf475f60d564cd3fb708e99b92efe… (And I made the same change to STON in JSON mode) > cheers -ben > > On Sat, 23 Feb 2019 at 05:24, Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > Good catch. > > Indeed, JSON keys have to be strings. > > The question is, should the writer convert them for you, or should you simply not use them ? > > I mean, there are many Pharo constructs that cannot be converted to JSON. > > Some could be output to JSON, but you won't be able to read them back in. > > So, if conversion would happen, the dictionary with integer keys will be read back with strings keys. > > In STON, keys can be anything, even complex objects, like in Pharo itself. > > What will you do with { (1@2)->100 } asDictionary in JSON ? > > I have to think about this. > > > On 22 Feb 2019, at 21:21, Esteban Maringolo <emaringolo(a)gmail.com> wrote: > > > > If you convert a Dictionary with numbers as keys it will produce not > > valid JSON [1], since all object keys must be quoted. > > > > E.g. > > NeoJSONWriter toString: (Dictionary with: 1->'foo'). > > or > > (Dictionary with: 1->'foo') asJson > > > > Should the library generate quoted keys? > > > > Seaside's WAJsonCanvas is manual, so it is up to the developer to > > render the object properly, but NeoJSON does it automatically. > > > > In Javascript this will throw a syntax error: > >> JSON.parse('{1: "foo"}') > > > > And this would generate a quoted key when serialized: > >> JSON.stringify({1: "foo"}) > >> {"1": "foo"} > > > > So my question is: should the library quote whatever you put as key in > > order to produce valid JSON syntax?
