Cannot assign theme in React

Question

I need to compile a UniswapV2 fork, but it doesn't want to compile. The error is below.

TypeScript error in /src/components/AccountDetails/index.tsx(230,28): Argument of type 'import("/node_modules/@types/react-redux/node_modules/@types/react/index").Context<import("/node_modules/@types/styled-components/index").DefaultTheme>' is not assignable to parameter of type 'React.Context<import("/node_modules/@types/styled-components/index").DefaultTheme>'. TS2345

        228 | }: AccountDetailsProps) {
        229 |   const { chainId, account, connector } = useActiveWeb3React()
      > 230 |   const theme = useContext(ThemeContext)
            |                            ^
        231 |   const dispatch = useDispatch<AppDispatch>()
        232 | 
        233 |   function formatConnectorName() {

Theme context is defined like this:

export const ThemeContext: React.Context<AnyIfEmpty<DefaultTheme>>;

Answer 1

You are using a single iterator both in a loop and using next. That can get confusing. Think about it:

• at iteration i, line is line k and next_line is line k+1.
• at iteration i+1, line is now line k+2.

You need to pass/save one line between iterations. Using a sample file of consecutive numbers in each line:

1
2
3
...

Using the code:

with open("text.txt") as file:
    line = next(file)
    for next_line in file:
        print(line.strip())
        print(next_line.strip())
        print("---")
        line = next_line

Will give:

1
2
---
2
3
---
3
4
---
...

Answer 2

You could simply track the previous line, separately, at update at the end of each iteration:

prev_line = None
with open("THUMlog.txt", "r") as file:
    for line in file:
        if line == "#DATE TIME TEMPERATURE UNIT HUMIDITY%\n":
            continue
        stripped_line = line.rstrip().split()
        if prev_line:
            print(f"Stripped: {prev_line}")
            print(f"Next: {line}")
        prev_line = line

Answer 3

You can do this by rewinding the position within the current file.

with open(...) as fh:
    pos = fh.tell() # This is where we want to go back to
    # Do what ever you want such as read lines.
    if INEEDTOGOBACK:
        fh.seek(pos)
