list.h | Linear Linked List Library | Authorization library

I am fiddling with the basics of type-level programming in Haskell, and I was trying to write a function that "homogenizes" a heterogeneous list using a function with a context of kind (* -> *) -> Constraint (e.g., length or fmap (/= x)).

The heterogeneous list is defined as follows:

I am trying to scrape title but they say your xpath is wrong

I am creating a module in Prestashop with Symfony but when I try to access my routes I get this error:

The controller for URI "/modules/youtuber/list" is not callable: Class "Myyoutubemc\Controller\YoutubeController"

Below is my controller it's located in: /modules/myyotubemc/src/controllers/youtubeController.php

I have to simplify custom regex expressions parsed to a certain data type. With "simplify" I mean the following (emphasis mine):

Given the rules:

• lowercase letters match themselves, eg.: a matches a and nothing else
• parens enclosing only letters match their full sequence, eg.: (abc) matches abc and nothing else
• square brackets enclosing only letters match every letters inside, eg.: [abc] matches a and b and c and nothing else

The following are all valid:

• (a[bc]) matches ab and ac and nothing else
• [a(bc)] matches a and bc and nothing else
• (a(bc)) is the same as (abc) and matches abc and nothing else
• [a[bc]] is the same as [abc] and matches a and b and c and nothing else

Regexes can be simplified. For example [a[[bb]b[[b]]](c)(d)] is really just the same as [abcd] which matches a, b, c and d.

I have implemented a simple parser combinator in Haskell using attoparsec and the following destination data type:

I'm looking at the Linked List implementation from here, and it shows how the class conforms to the Collection protocol:

I am using semanti-UI-react. The Ui I want to achieve is a modal which is divided vertically in 2 parts. The left side shows a video and the right shows timestamps and descriptions of indices of the video. My right side with the indices should be scrollable.

I am trying to implement a direct acyclic graph with the boost::adjacency_list<> class. For that I re-implemented the idea from this question: boost graph that doesn't allow circular references

I have a few problems, cannot figure it out, maybe there are connected.

Problem 1.1: file is exported in django documentation and it works, but when I try to rename it, it has some error. I want to be like this with pd.ExcelWriter(newdoc + 'output.xlsx') as writer: in order to every file has a "new" name. I got this error, TypeError at / unsupported operand type(s) for +: 'InMemoryUploadedFile' and 'str'

Problem 1.2: How to add path where to save?

Problem 2: I get to download file but it is empty, and name of document is Donwload.xlsx. I want to be like this, but this got many errors...
