poetry init does not find the package if the search string is capitalized

[cu]

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Pop OS 21.04
• Poetry version: 1.1.12
• Link of a Gist with the contents of your pyproject.toml file:

Issue

In the package selection part of the poetry init wizard, package selection only works reliably if you use a fully lowercase search string. If you capitalize the search string, a package matching that string will not show up in the results.

Say I want to add Flask as a dependency. The package name on this project is capitalized on PyPI. If I search for flask, the package will show up in the results. If I search for Flask, it will not.

$ poetry init -vvv

This command will guide you through creating your pyproject.toml config.

Package name [notes]:  
Version [0.1.0]:  
Description []:  
Author [<censored>, n to skip]:  
License []:  
Compatible Python versions [^3.9]:  

Would you like to define your main dependencies interactively? (yes/no) [yes] 
You can specify a package in the following forms:
  - A single name (requests)
  - A name and a constraint (requests@^2.23.0)
  - A git url (git+https://github.com/python-poetry/poetry.git)
  - A git url with a revision (git+https://github.com/python-poetry/poetry.git#develop)
  - A file path (../my-package/my-package.whl)
  - A directory (../my-package/)
  - A url (https://example.com/packages/my-package-0.1.0.tar.gz)

Search for package to add (or leave blank to continue): Flask
Found 20 packages matching Flask

Enter package # to add, or the complete package name if it is not listed: 
 [0] Flask-Zipper
 [1] Flask-DB
 [2] flask-beans
 [3] Flask-Sessions
 [4] Flask-SimpleACL
 [5] flask-blacklist
 [6] Flask-Shelve
 [7] flask_wifiqr
 [8] Flask-Account
 [9] Flask-OpenID

Hello @cu,

thanks for reporting.

The problem are in these lines:

poetry/src/poetry/console/commands/init.py

Lines 272 to 278 in ecb030e

	matches_names = [p.name for p in matches]
	exact_match = constraint["name"] in matches_names
	if exact_match:
	choices.append(
	matches[matches_names.index(constraint["name"])].pretty_name
	)

We should use the canonical name of constraint["name"] to find in "exact" match in the list of results. Because we don't do it now, the result for "Flask" isn't put in front of the result list we present to the user. Together with the fact that the result list is cut down to 10 result this package is hide.

@finswimmer mind if I take this one? I've forked and am starting development, but if it's already assigned, don't want to step on any toes

Hey @evanrittenhouse,

yes, feel free to start working on it 👍
