Monty, do these (already) work with all the latest changes in Pharo 7, I mean the deprecation of FileStream and subclasses as well as [RW|MultiByte]BinaryOrTextStream for FileReference, File and Zn streams ? If not, we should help you. Sven
Re: [Pharo-users] Lost in stream
Are you developing in Squeak? I ask because the XML parser in the default Squeak image is very old. You can download the latest Pharo XMLParser lib from the SqueakMap. It's the "XMLParser" project. Other libs I maintain are also available as SM projects, like "XMLParser-XPath". If you're doing DOM parsing, you can save a parsed DOM document to a file using a message like #printToFileNamed: (see the XMLNode "printing" category for more). ___ montyos.wordpress.com > Sent: Saturday, June 16, 2018 at 4:27 AM > From: Hilaire > To: pharo-users@lists.pharo.org > Subject: Re: [Pharo-users] Lost in stream > > Sometime you just need a good sleep, which I was fortunate to have. > > My newer code append contents to existing file, so it lead to corrupted > files at the end.

Re: [Pharo-users] Lost in stream
Print-evaluate this: ' ' parseXML and you should get (with any recent XMLParser lib): If you don't want entity replacement, set #replacesContentEntityReferences: to false. Also consider using XMLParser's built-in file reading support: #parseFileNamed:/#onFileNamed:. They work cross platform (Squeak, GS), and handle character decoding. ___ montyos.wordpress.com > Sent: Saturday, June 16, 2018 at 4:27 AM > From: Hilaire > To: pharo-users@lists.pharo.org > Subject: Re: [Pharo-users] Lost in stream > > Sometime you just need a good sleep, which I was fortunate to have. > > My newer code append contents to existing file, so it lead to corrupted > files at the end.

Re: [Pharo-users] Windows installation broken?
This is what concerns me. I don't care that there are workarounds (undocumented or hard to find). I care that Windows is a most popular development platform. I care that newcomers to Pharo easily find what they need to get started. I care about Pharo's reputation. The last thing Pharo needs is a black eye.

Re: [Pharo-users] Windows installation broken?
The current website shows the wrong link, the installer for the bleeding edge is the wrong one in files. The situation on the Windows front is very very bad and not really improving. That being said, the installer on the CI is the right one and works. so, steal the installer from here: https://ci.inria.fr/pharo-ci-jenkins2/job/PharoLauncher This is the one you want: https://ci.inria.fr/pharo-ci-jenkins2/job/PharoLauncher/ For having the latest lastet everything, go to the launcher settings, get into the devmode and open monticello and load the latest packages.

Yes. Indeed thats where I copied my selector naming from, although I

NeoJSONPropertyMapping >> listOfType:withElementSchema:
However NeoJSONCustomMappings seems only accessible through "reader for:

while instance variable interaction seems only possible using "reader for:

So it seems NeoJSONCustomMapping lacks #mapAccessor* methods
while NeoJSONObjectMapping lacks #listOfType:* methods
and "never the twain shall meet".
I didn't look closely at #mapWithValueSchema:
but its covering tests seem to operate on Dictionaries rather than Arrays.

Yes, but how to mix those list* methods with poking the result into an
instance variable
to be able to "assign a list of elements to an instance variable" as a one
liner?
I'd be glad to be shown another way to do this for the given data.
I see a few #testLists examples, but none that assign the result to an
instance variable.
NeoJSONExamplesTests has some "lists of objects" tests, but no "objects
with lists"
A useful example would be #testPolygonPoints...
NeoJSONExamplesTests >> testPolygonPoints
| polygon polygonJson result |
polygon := Polygon new vertices: { 1@2. 3@4. 5@6 }.
polygonJson :=
'{ "vertices": ["I'm not clear on how to do the writer side of things"
{
"x" : 1,
"y" : 2
},
{
"x" : 3,
"y" : 4
},
{
"x" : 5,
"y" : 6
}]
}'.
result := (NeoJSONReader on: polygonJson readStream)
mapInstVarsFor: Point;
for: Polygon do: [ :mapping |
(mapping mapInstVar: #vertices) listOfType: Array withElementSchema: Point];
nextAs: Polygon.
self assert: result equals: polygon
Some equality support is needed for Polygon (PathShape)
(my best guess, discussion of this might be worth a separate thread)
PathShape >> = aPathShape
|otherVertices equal|
otherVertices := aPathShape vertices.
(self species = aPathShape species) & (vertices size = otherVertices size)
ifFalse: [ ^false ].
1 to: vertices size do: [ :i |
(vertices at: i) = (otherVertices at: i) ifFalse: [^false] ].
^true

hash := 0.
1 to: vertices size do: [ :i | hash bitXor: (vertices at: i) ].
