Re: [Pharo-users] STON shouldn't care about shared references in JSON mode

by Peter UhnÃ¡k

Ah sorry, I'm blind. Yes, ideally it should throw up an error in case of recursive. And I see that NeoJSON runs into infinite cycle, so I guess this should be addressed there too.

To keep STON practices / assumptions while using JSON to hold the data where STON is not supported yet, maybe? IIRC STON is positioning itself as JSON superset; but maybe only syntactic superset, while semantically it can be a bit different (so STONize to more low-level, JSON, syntax via STON; JSONize faithfully to JSON semantics using NeoJSON; but maybe I am just making things up). > Herbert: I am not talking about (infinitely) recursive references, but I know; Sven explicitly asked what to do with cycles in that case, though. > referencing the same object, e.g. > > > Peter > > On Tue, Mar 27, 2018 at 6:08 PM, Herbert VojÄÃk <herby(a)mailbox.sk > <mailto:herby@mailbox.sk>> wrote: > > > > Sven Van Caekenberghe wrote: > > Hi Peter, > > Both cases will pass using this expression: > > String streamContents: [ :out | > STON jsonWriter > referencePolicy: #ignore; > on: out; > nextPut: d ]. > > The problem is what to do with cycles. > > > Be faithful to what JSON.stringify does in JS.

Re: [Pharo-users] fuel docs shows the same content twice

by Peter UhnÃ¡k

In fact this is problem on every page: it shows the Getting Started on the top, and then continues with the actual content of the page, e.g. https://rmod.inria.fr/web/software/Fuel/Version1.9/Documentation/Globals?_s… On Tue, Mar 27, 2018 at 6:29 PM, Peter UhnÃ¡k <i.uhnak(a)gmail.com> wrote: > Hi, > > not sure where to report this, but in this page of fuel docs > > https://rmod.inria.fr/web/software/Fuel/Version1.9/ > Documentation/GettingStarted?_s=gnS5amSI-7GcDf_k&_k=4e8w5tCS4RRm35p7&_n&18 > > all the chapters are twice there > > Basic examples > ... > FileStream > ... > Compressing > ... > Showing a progress bar > ... > Basic examples > ... > FileStream > ... > Compressing > ... > Showing a progress bar > ... > > Peter >

Re: [Pharo-users] STON shouldn't care about shared references in JSON mode

by Peter UhnÃ¡k

Hi Sven, shouldn't it be set to #ignore by default for JSON then? Or is there a use case where it makes sense to have something else for JSON?

Hi Peter, Both cases will pass using this expression: String streamContents: [ :out | STON jsonWriter referencePolicy: #ignore; on: out; nextPut: d ]. The problem is what to do with cycles.

RTLegendBuilder onDemand doesn't popup in html

by Andrei Stebakov

Just wanted to report that when I add a legend to RTView, it works as expected when I ispect the view. When I export it to HTML, it shows the node, but neither mouse clicking nor hovering bring up the popup. Could you take a look?

STON shouldn't care about shared references in JSON mode

by Peter UhnÃ¡k

Hi, I don't think this should throw an error when I am producing JSON. ``` d := { 'a' -> #(). 'b' -> #(). } asDictionary. STON toJsonString: d. ``` dtto this ``` a := {'hm'}. d := { 'a' -> a. 'b' -> a. } asDictionary. STON toJsonString: d. ``` Maybe I should forgo using STON>>toJson* out of laziness (it is preinstalled) and always go for NeoJSON? Peter
