@LukasLang Shipping multiple versions is something I am absolutely not willing to do ... maintaining the package is already a lot of work.

How to tell import to inteprete .xlsx files dates as date lists instead of date objects?

1:22 PM

@Kuba You use MUnit, right? Can I have setup steps in a testing notebook? I.e. can I have some code evaluated before any tests are run, without making that code part of a test? E.g. set up helper functions for writing tests concisely.

@Szabolcs I use VerificationTest, TestReport etc.

Which is built on top of MUnit I think

so in a test file I can have whatever I need to be run

(not to confuse things with test notebooks that are a mess)

Anyway, so far it works well, just remember to use $TestFileName instead $InputFileName

@Szabolcs The problem with test notebooks is that they are parsed at once and then evaluated so yes you can setup things but not $Context sensitive things because you will have your file parsed before anyway.

Not to mention other problems mathematica.stackexchange.com/questions/176551/…

@Szabolcs I would also suggest using VerificationTest and TestReport functions in a package file and stay away from testing notebooks. This approach works well for me and you add whatever setup code you need.

@Kuba Does this symbol that you mentioned $TestFileName work for the same purpose as $InputFileName? But I could not find it in MUnit context? I only found $CurrentFile which seems to do the same thing.

2:17 PM

@Pinti I was not using MUnit before VerificationTest came and the first thing I faced was $TestFileName that is mentioned in ref/TestReport.

Not by my own, I think I was confused and discussed the issue in this chat

And then it emerged

3:02 PM

@Kuba That's a good point. I did not know that there was a difference.

@Szabolcs I can't say I've really looking into the Loading option since I never use anything but Manual

@Kuba That is curious, I cannot find the symbol $TestFileName anywhere on ref/TestReport or other documentation pages either (on MMA 11.3).

@b3m2a1 Is your paclet installer set up such that PublicPacletInstall will get it directly from GitHub (meaning that the download counter will be incremented)?

@Szabolcs It will if there is a release specified when I build the server. I'd like to make this more automatic but haven't yet.

@b3m2a1 I was going to submit this one, with the same feature if possible: github.com/szhorvat/BoolEval I just made the first release.

Sounds good. When you make the issue just put that it's a release on there. There's a template you can fill out if you want here: paclets.github.io/PacletServer/pages/submit.html

@b3m2a1 So do you manually process whatever I submit there?

Issue created. Hope I got it right.

6:54 PM

@Szabolcs Yeah I'm still manually processing things. Not worth it to automate yet.

I'll build in the new stuff today

@b3m2a1 which is your recent approach to minimal oop?

7:16 PM

@Kuba recently I've been doing a lot with this paclet: paclets.github.io/PacletServer/interfaceobjects.html

It gives me a state-less way to do OOP like stuff

Here's an example of the kind of thing I do with it:

<< InterfaceObjects`

RegisterInterface[
 objHead,
 {"Prop"}
 ]

objHead

woofImp[obj_] :=
 Print["woof"]

InterfaceMethod[objHead]@
  o_objHead["Woof"][] := woofImp[o]

obj = objHead[<|"Prop" -> 1|>]

Apply[objHead, {
Association["Prop" -> 1, "Version" -> 1]}]

obj["Prop"]

1

obj@"Woof"[]

woof

The paclet itself provides actually a pretty rich interface, but that's the quickest way to getting oop I know

Ah yeah that Apply thing is just a formatting artifact

It formats as a SummaryBox but the InputForm syntax works through Apply

If you want a way to store properties on an object itself as opposed to a symbol (useful for caching) these things support the Property* interface (e.g. SetProperty[obj, "asd" -> 1]) through Language`ExpressionStore

Means there aren't memory leaks

They also can support MutationHandler syntax if you change the RegisterInterface call to:

RegisterInterface[
 objHead,
 {"Prop"},
 "MutationFunctions" -> {"Keys"}
 ]

@Kuba have you ever gotten NotebookInformation to crash the kernel...?

I am currently managing that but don't know what exactly I'm doing that is causing it

9:09 PM

@b3m2a1 Most likely yes but I don't remember details :)

@b3m2a1 at IO:

> PacletInstall::dwnld: An error occurred downloading paclet InterfaceObjects-1.0.1 from site http://raw.githubusercontent.com/paclets/Repository/master: File not found on server..

9:20 PM

@Kuba Huh looks like the paclet never made it into the repository. Maybe I cancelled that build half way through. I'll make sure it ends up there when I build the server a little bit later.

I think the crash occurs if the Stylesheet gets corrupted or something

What's concerning is it looks like that kind of corruption is entirely possible in a documented way
