Am trying to get a list of ids from a table as an array/list of integers, then encoding that with Thoth and outputting.
ANSWERAnswered 2021-Apr-05 at 02:27
The 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:
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.
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,

open Thoth.Json.Net let deserialiseDictionary (s: string) = s |> Decode.unsafeFromString (Decode.keyValuePairs Decode.string) |> Map.ofList let printDictionary json = json |> deserialiseDictionary |> fun m -> printfn "%s" m.["hello"] // Hello
I’m sure there will be a barrage of stupid questions from me as I migrate away from the extremely loose PHP to F#.
This one should hopefully be straightforward. I have a json file...

Using Thoth the magic method is Decode.keyValuePairs.
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 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 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:

This should do it:
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:...
ANSWERAnswered 2020-Nov-16 at 17:11
The problem is that you don't control the code. If you had control over it, a solution would be:
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
<*> 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.

ANSWERAnswered 2020-May-14 at 06:08
So after a bunch more research, the issue was with the translation from TS to Python. It's important to remember that where parameters e.g. the value of integration_response, it is still TS. I found
I also found adding api_gateway method responses a bit non-intuitive as well, so in my working example below I've included it.
In my library I have seperated the public headers from the source by putting them into
src. While using Cmake I have this for my library :
ANSWERAnswered 2020-Apr-11 at 03:59
All the headers included by the user of the library, either directly or transitively, should be in /include.
LibInternal.h and the user includes
LibInternal.h should also be in /include, because the user includes
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
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.
I am trying to follow the tutorial at https://coaxion.net/blog/2018/01/how-to-write-gstreamer-elements-in-rust-part-1-a-video-filter-for-converting-rgb-to-grayscale/ about writing gstreamer plugins using rust.

ANSWERAnswered 2019-Jul-16 at 15:40
Your problem is that you're still using the
gst-plugin crate, but that's obsolete nowadays and everything's part of the
gstreamer-base / etc crates now if you enable the
subclass feature of them. See the links above for the details.
Depending on the old version of the
gst-plugin crate will pull in an older version of the
glib-sys (and others) crate, and you can't have two different versions of a
-sys crate in the same project.
You'll have the same problem again if you uncomment the
glib dependency. Once you update that to the
0.8 version of
glib, that error would also go away.
I'm trying to validate all versions in a
versions.json file, and get as the output a json with only the invalid versions.

You can use thoth like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the thoth component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
