kandi X-RAY | ts-toolbelt Summary
ts-toolbelt is the largest, and most tested type library available right now, featuring +200 utilities. Our type collection packages some of the most advanced mapped types, conditional types, and recursive types on the market. Spend less time, build stronger. Benefit from a wide range of generic type functions to achieve better type safety. We work just like lodash, or ramda, but applied to the type system. Our mission is to provide you with simple ways to compute, change, and create types. We abstract all those complex type checks away for you. We provide a simple, reusable, and standard API to help you get more done with TypeScript. ts-toolbelt is a well organized package that can help you perform advanced operations on object types, union types, as well as function, and literal types. It is carefully and coherently designed for building robust, flexible, and type-safe software.

QUESTION
to build and run a local instance, im following the tutorial at
https://haha.readthedocs.io/en/latest/install.html
but i use the git repo
https://github.com/readthedocs/readthedocs.org.git
instead of
https://github.com/rtfd/readthedocs.org.git
for the "git clone" command, as the link in the tutorial does not exist.
i am also using venv

I want to install packages from poetry.lock
file; using poetry install
.
However, the majority of packages throw the exact same error, indicating a shared fundamental problem.
What is causing this? What is the standard fix?
Specification:
- Windows 10,
- Visual Studio Code,
- Python 3.8.10 & Poetry 1.1.11,
- Ubuntu Bash.
Terminal:
rm poetry.lock
poetry update
poetry install
ANSWER
Answered 2022-Mar-23 at 10:22This looks to be an active issue relating to poetry. See here - Issue #4085. Some suggest a workaround by downgrading poetry-core
down to 1.0.4.
There is an active PR to fix the issue.

I am fairly new to Ansible and have now started automating some repetitive Windows administration tasks.
As a controller I use a Debian 11 VM where I have only Ansible and pywinrm installed. My test target is a Windows Server 2016 and everything works fine, I can install programs, create users or copy files. The only thing that does not work is the module "win_updates".
I get the following message back when I call win_updates.

QUESTION
The aim is to define a Function type that only accept a certain amount of mandatory parameters.
Thanks to @jcalz who helped me define the type OnlyTupleRequired
which allow to remove any optional arguments and thus far allow to know the length of the parameters even when they includes optional ones, I've managed to do it.
Now I would like the compiler to complain at the definition of a function not at the use of them - any comment stating 'should error' should emit an error and don't.
Here's the link to the playground
...ANSWER
Answered 2022-Jan-14 at 03:09So your definition of FunctionT
doesn't prevent a "bad" P
from being assigned to it. The only constraint you have is L.List
(something specific to ts-toolbelt which is, I guess, just ReadonlyArray
🤷♂️). But you specifically care about making sure that it has at most two required parameters (or something like it). So you want to ensure both P extends L.List
and that N.LowerEq
["length"], MaxParametersCount> extends 1
. Currently you are having FunctionT
evaluate to never
if the latter check isn't true. But maybe we can rewrite the definition so that P
is actually constrained:

no module stdnum
actually there is a problem with pip so make sure your pip path with which pip or which python
- to solve .venv that doesn't work by deleting the .venv folder, create venv in python, and install all requirements again
QUESTION
I am studying the source code of the ts-toolbelt library.
And I often meet this expressionO extends unknown
. In my opinion, it does not add any functionality.
And so I wondered, what is it for?
...ANSWER
Answered 2021-Dec-12 at 01:13Presumably the library authors decided that UnionOf
should produce the same result as UnionOf
| UnionOf | UnionOf
, and the definition of _UnionOf
did not do that. The O extends unknown ? ... : never
check, which deceptively looks like it does nothing, causes that to happen.
Expressions that look like they do nothing but actually distribute across unions, when T
is a generic type parameter:
T extends unknown ? ... : never
T extends any ? ... : never
T extends T ? ... : never
If T
is a type parameter, as in the generic function function foo(/*...*/): void
or the generic interface interface Foo {/*...*/}
, then a type of the form T extends XXX ? YYY : ZZZ
is a distributive conditional type.
It distributes the conditional check across unions in T
. When T
is specified with some specific type, the compiler splits that type up into its union members, evaluates the check for each such member, and then joins the results back into a new union. So if F
distributes across unions, then F
will be the same as F
| F | F
.
Not all type functions are distributive across unions. For example, the keyof
operator does not turn unions of inputs into unions of outputs:

I have an anaconda environment that has Python 3.7 installed. I have a file with some imports out of order which I want VScode to order when pressing CRTL+s
.
However, instead or ordering the imports, there is a crash and nothing happens.
ProblemWhen I press CRTL+s
on my VScode, I get a pop up saying the Python extension crashes. After some investigation, this is the stack-trace I found:
ANSWER
Answered 2021-Oct-27 at 09:34The problem here is that I had broken dependencies which would not allow me to do any updates nor new installs.
This had to do with having packages from both conda
and pip
. Some of them play nice together, some don't.
My solution, was unfortunately, rather atomic. I deleted the environment and created a new one with Python 3.7.
Upon doing that, I also added an extra conda channel conda-forge
which I recommend instead of pip
.
Once I did that I installed all the dependencies and packages using conda
and it worked.
