Resolves: #2115

'An' should come before a vowel sound.

Reference: https://english.stackexchange.com/a/164/198117

When testing the behavior for git packages with a setup.py file, the Provider class would create a temporary virtual environment and execute python setup.py egg_info. Both actions are costly and take time. By mocking them, we can reduce the tests time by a factor of 4 or 5.

* Add fish shell tab completion for mac

* Remove macOS ref as brew should work linux as well

If multiple distributions have `tests` as a top-level package, they'll conflict whenever both are installed. (Examples [here]((https://github.com/python-poetry/poetry/issues/1905) and [here](https://github.com/NixOS/nixpkgs/issues/81482). Two common alternative strategies are:

1. not distributing tests (as [here](https://github.com/pypa/sampleproject)), or 
2. placing tests in a subdirectory of the main package, rather than adjacent (as [here](http://blog.habnab.it/blog/2013/07/21/python-packages-and-you/) and [here](http://as.ynchrono.us/2007/12/filesystem-structure-of-python-project_21.html)). Each of these strategies will avoid this issue. 

Users may fall into this trap because of the [package documentation](https://python-poetry.org/docs/pyproject/#packages) page, which gives an example:

```
packages = [
    { include = "my_package" },
    { include = "tests", format = "sdist" },
]
```

Having two top-level packages in a distribution is relatively unusual, but does have some use cases.  Using `"tests"` as a top-level package name in the example is likely to lead to conflicts, however. The alternate package in the documentation example could have a unique name like `"my_other_package"`, which would reduce the likelihood of this kind of overlap.

Resolves: #2198

Configuring the template chooser to include discord community server.

Document --no-root

Add a subsection on documenting the --no-root option in the Basic Usage section and also in the CLI. Resolves #1848.

This reverts commit bf12e427.

* export: fix exporting extras sub-dependencies (#1294)

* Support POETRY_HOME for install (#794)

Allow the `POETRY_HOME` environment variable to be passed during installation to change the default installation directory of `~/.poetry`:

```
POETRY_HOME=/etc/poetry python get-poetry.py
```

* * check if relative filename is in excluded file list (#1459)

* * check if relative filename is in excluded file list
* removed find_excluded_files() method from wheel.py

* added test for excluding files in wheels

* creating an own test data folder, for testing excluding files by pyproject.toml

* use as_posix() to respect windows file path delimiters

* Exclude nested items (#784) (#1464)

* This PR impliments the feature request #784.

When a folder is explicit defined in `pyproject.toml` as excluded, all nested data, including subfolder, are excluded. It is no longer neccessary to use the glob `folder/**/*`

* use `Path` instead of `os.path.join` to create string for globbing

* try to fix linting error

* create glob pattern string by concatenating and not using Path

* using `os.path.isdir()`` for checking of explicit excluded name is a folder, because pathlib's `is_dir()` raises in exception under windows of name contains globing characters

* Remove nested data when wildcards where used.

Steps to do this are:
1. expand any wildcard used
2. if expanded path is a folder append  **/* and expand again

* fix linting

* only glob a second time if path is dir

* implement @sdispater 's suggestion for better readability

* fix glob for windows?

* On Windows, testing if a path with a glob is a directory will raise an OSError

* pathlibs  glob function doesn't return the correct case (https://bugs.python.org/issue26655). So switching back to  glob.glob()

* removing obsolete imports

* Update dependencies

* Deprecate allows-prereleases in favor of allow-prereleases for consistency

* Fix tests for Python 2.7

* Fix linting

* Fix linting

* Fix linting

* Fix typing import

* Correct a couple typos in get-poetry.py (#573)

* Docs: `self:update` changed to `self update` (#1588)

* Merge master into develop (#2070)

* Fix Github actions cache issues (#1908)

* Fix case of `-f` flag

* Make it clearer what options to pass to `--format`

* fix (masonry.api): `get_requires_for_build_wheel` must return additional list of requirements for building a package, not listed in `pyproject.toml` and not dependencies for the package itself (#1875)

fix (tests): adopted tests

* Lazy Keyring intialization for PasswordManager (#1892)

* Fix Github Actions cache issues (#1928)

* Avoid nested quantifiers with overlapping character space on git url parsing (#1902 (#1913)

* fix (git): match for `\w` instead of `.` for getting user

* change (vcs.git): hold pattern of the regex parts in a dictionary to be consistent over all regexs

* new (vcs.git): test for `parse_url` and some fixes for the regex pattern

* new (vcs.git): test for `parse_url` with string that should fail

* fix (test.vcs.git): make flake8 happy

* fix: correct parsing of wheel version with regex. (#1932)

The previous regexp was only taking the first integer of the version number,
this presented problems when the major version number reached double digits.

Poetry would determine that the version of the dependency is '1', rather than,
ie: '14'. This caused failures to solve versions.

* Fix errors when using the --help option (#1910)

* Fix how repository credentials are retrieved from env vars (#1909)

# Conflicts:
#	poetry/utils/password_manager.py

* Fix downloading packages from Simplepypi (#1851)

* unused code removed

* remove unused imports

* Upgrade dependencies for the 1.0.3 release (#1965)

* Bump version to 1.0.3 (#1966)

* Fix non-compliant Git URL matching

RFC 3986 § 2.3 permits more characters in a URL than were matched. This
corrects that, though there may be other deficiencies. This was a
regression from v1.0.2, where at least “.” was matched without error.

* Update README.md "Updating Poetry"

Currently the note in "Updating Poetry" is different from the one below in "Enable tab completion for Bash, Fish, or Zsh". This MR is to make them more consistent.

* init: change dev dependency prompt

* Fix CI issues (#2069)

* pre-commit: replace isort mirror with isort upstream (#2118)

The isort pre-commit mirror has been deprecated. This change updates
configuration to use the upstream package repository instead of the
mirror.

* Add cache list command (#1187)

* Add poetry.locations.REPOSITORY_CACHE_DIR

The repository cache directory is used in multiple places in the
codebase. This change ensures that the value is reused.

* Add cache list command

This introduces a new cache sub-command that lists all available
caches.
