QUESTION
I have a JSON document that I'm parsing using Thoth.Json.Net. The document has an array containing a set of objects that each have a "type" attribute with a value that identifies their type. Each of these types needs a different decoder so I need to be able to provide some sort of filter based on the value of the "type" attribute. How can I do this?
Update:After getting the "hack" that I describe above working, I revisited using the CE and decodeByType custom decoder, with each decoder returning a value from a Discriminated Union as mentioned by @tranquillity above. Once I had got my head around all the types the only thing I had to do was to specify the types for the Builder:

Answered 2021-Apr-05 at 02:27The problem is that your listOfIds function doesn't return an array of numbers. It returns a function instead.
If you ask whatever IDE you're using what the type of listOfIds is, it will tell you something like this:
QUESTION
I'm redoing the backend of a very basic framework that connects to a completely customizable frontend. It was originally in PHP but for the refactor have been plodding away in F#. Although it seems like PHP might be the more suited language. But people keep telling me you can do everything in F# and I like the syntax and need to learn and this seemingly simple project has me stumped when it comes to JSON. This is a further fleshed out version of my question yesterday, but it got alot more complex than I thought.
Here goes.
The frontend is basically a collection of HTML files, which are simply loaded in PHP and preg_replace() is used to replace things like [var: varName] or [var: array|key] or the troublesome one: [lang: hello]. That needs to be replaced by a variable defined in a translation dictionary, which is stored as JSON which is also editable by a non-programmer.
I can't change the frontend or the JSON files, and both are designed to be edited by non-programmers so it is very likely that there will be errors, calls to language variables that don't exist etc.
So we might have 2 json files, english.json and french.json
english.json contains:

I´m struggling formulating a regular expression to extract all the species names (group1) and the author names (group2) from a list. I´m fairly new to python and would appreciate any help.
This is a part of the list:
Dalbergia acutifoliolata Mendonca & Sousa
Dalbergia adami Berhaut
Dalbergia afzeliana G.Don
Dalbergia agudeloi J.Linares & M. Sousa
Dalbergia albiflora Hutch. & Dalziel
Dalbergia altissima Baker f.
Dalbergia amazonica (Radlk.) Ducke
Dalbergia amerimmon L. ex B.D.Jacks
Dalbergia andapensis Bosser & R.Rabev.
Dalbergia arbutifolia Baker
Dalbergia arbutifolia aberrans Polhill
Dalbergia armata E.Mey.
Dalbergia assamica Benth.
Dalbergia aurea Bosser & R.Rabev.
Dalbergia baronii Baker
Dalbergia bathiei R.Vig.
Dalbergia benthamii
Dalbergia berteroi
Dalbergia pseudo-sissoo Miq.
Dalbergia ovata var. glomeriflora (Kurz) Thoth.
Dalbergia albiflora subsp. albiflora
Usually species names have a genus and a species name, and some have a subspecies name. I can catch those with:

QUESTION
I have found this superb JSON library for F#, it's inspired by Elm's Json.Decode and it defines a basic Decoder type like this:
type Decoder<'T> = string -> obj -> Result<'T, DecoderError> (here)
There are functions like Decode.map and I wish I could make it F#+ compatible, so I could use it like:
let customerId = Decode.string |>> CustomerId
(see |>> infix version of generic map)
As far as I can see, to make a 3rd party library use F#+ concepts like Functors, one needs to extend the 3rd party type with static member Map, but the Decoder<'T> is just an abbreviation.
Is there any solution? Did anyone try?
P.S. My solution so far is a custom binding:
...ANSWER
Answered 2020-Nov-16 at 17:11The problem is that you don't control the code. If you had control over it, a solution would be:
Implement
Decoderas a concrete type as opposed to a type alias. A type alias can't have additional members, because it's not really another type. Library authors should use single case discriminated unions, now that you can make them structs with nearly zero overhead.Add the member
Mapwith the required signature.
Alternatively, if extensions members becomes visible for trait constraints in a future F# version, you would be able just extend the type with the Map function, maybe with some undesired effects as it's a type alias for a function with 2 arguments.
So, I think the best you can do is what you already showed.
As a side note, you might be interested in having a look at Fleece which also provides decoders, but it also goes one step further and provides you codecs which goes in both directions (and you can map and <*> over it).

I'm trying to use the AWS_CDK for python to provision an apigateway integration. The typescript on https://pypi.org/project/aws-cdk.aws-apigateway/1.4.0/ is helpful, as is the unchecked python translation on https://docs.aws.amazon.com/cdk/api/latest/python/aws_cdk.aws_apigateway.README.html but it's not quite right.
I've tried to get the python version correct but I'm still missing something in the translation from TS to python. Currently my code snippet is;

QUESTION
In my library I have seperated the public headers from the source by putting them into include and src. While using Cmake I have this for my library :
ANSWER
Answered 2020-Apr-11 at 03:59All the headers included by the user of the library, either directly or transitively, should be in /include.
If LibInterface.h includes LibInternal.h and the user includes LibInterface.h, then LibInternal.h should also be in /include, because the user includes LibInternal.h transitively.
If you can avoid including LibInternal.h being included in LibInterface.h, do it. Sometimes you cannot, because LibInterface.h may depend on something defined in LibInternal.h.
If you want to discourage the user from directly including LibInternal.h, you could put it in a /include/detail or something like that.
In some cases, you can use pimpl idiom to break dependency between your interface and implementation, but that has also its disadvantages, so it's a tradeoff.

Install Thoth
You can use Thoth like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
