Please refer to the following syntax error and fix it asap please.

@navrkr you don't have the right to say "fix it ASAP please". You have the right to do the hard work and make a contribution if this is important to you. In addition please check your facts: this is not a syntax error. It is a dialyzer warning. And at this point in the development cycle I don't believe @cocoa-xu is focused on producing dialyzer-clean code.

No need to use alternative channels, that's what the issue tracker is for.

Sorry for saying ASAP, the thing is "i solved a problem in python completely" but I want it to implement in elixir, i find docs confusing but it is fine in initial release of project. I am new to elixir too 🫣. So I need some guidance and help to complete my project in time.

And also it is returning nil so Its a mandatory thing not just dialyzer-clear.

Hi @navrkr, the inline docs can be pulled up by typing h Evision.drawContours in iex. This is a builtin feature of iex.

Also, there is a nice-looking HTML version available on https://hexdocs.pm/evision/, and the one you're looking for can be found here https://hexdocs.pm/evision/Evision.html#drawContours/5.

If you are looking for the documentation of other functions, you can search the function name in the top-left search box on https://hexdocs.pm/evision/, or type h Evision.functionName (or h Evision.SubModule.functionName) in iex.

For example, to search for the usage of Evision.drawContours/{4,5} on https://hexdocs.pm/evision/, please type drawContours in the top-left search box and press the enter (windows) / return (macOS) key. The resulting list will show on the right side once you begin typing anything in the search box. Then you can click on it (or the one you want) in the list on the right side, and it will bring you to the corresponding section.

For all keyword arguments, they should be passed to the function like this:

Evision.function(
  positional_argument_1,
  positional_argument_2,
  name_of_first_keyword_argument: value_of_first_keyword_argument,
  name_of_the_second_keyword_argument: value_of_the_second_keyword_argument
)

For Evision.drawContours/5, it could be

Evision.drawContours(
  image,
  index,
  [0, 255, 255],
  thickness: -1,
  lineType: 0,
  hierarchy: hierarchy_info,
  maxLevel: 1,
)

Also, you don't need to pass a value for each keyword argument.

Evision.drawContours(
  image,
  index,
  [0, 255, 255],
  thickness: -1,
  lineType: 0,
  maxLevel: 1,
)

Thanks a ton, so sweet of you for taking time and explaining everything ☺️, I already had look at docs and it's great and helpful in a great way.🤟

No issues thanks for your support, i can manage to do it on my own as I already figured out how to do it on python!

Some (language) features available in Python are not in Elixir, and it's the same the other way around. It's hard to copy the code from one language and expect it to work in another one.

Please refer to the following syntax error and fix it asap please.

For this one, I've managed to generate function specs in PR #101. It's not released yet because I need some time to check if the generated specs are correct or not.

Producing dialyzer-clean code is on my list, but there are other things that I have to solve first.

As the main issue here has been solved, I'll close this issue for now.
