Installing poetry (0.11.0-alpha.3)

As far as I know, the re library doesn’t have any ability to support unicode character classes but regex can handle them properly.

I don’t know if this has been brought up before or this is a windows-only thing, considering this happened while poetry developing poetry itself. as far as I checked, nobody has made an issue about this before.

Windows 10, python 3.6.4, poetry 0.11.0a3.

edit: #66 is similar.

In the meantime, catching errors:

    def _get_author(self):  # type: () -> dict
+       if self._authors:
+           m = AUTHOR_REGEX.match(self._authors[0])
+       else:
+           m = None

-       if not self._authors:
+       if not m:
+           # log.info('Could not find an author') or whatever
            return {"name": None, "email": None}

        m = AUTHOR_REGEX.match(self._authors[0])

        name = m.group("name")
        email = m.group("email")

        return {"name": name, "email": email}

@jacebrowning Thanks for the pointer a few months back regarding AUTHOR_REGEX. After a bit of experimentation, I think that this has to do not with Poetry per se but rather with a bug in the re module (see https://github.com/lark-parser/lark/issues/590).

Replacing re with regex solves everything:

import re
AUTHOR_REGEX = re.compile(r"(?u)^(?P<name>[- .,\w\d'’\"()]+) <(?P<email>.+?)>$")
AUTHOR_REGEX.match("ம. ஆ. ஜூலீஎன் <[e-mail]>")
>>> None
# But...
import regex as re
AUTHOR_REGEX = re.compile(r"(?u)^(?P<name>[- .,\w\d'’\"()]+) <(?P<email>.+?)>$")
AUTHOR_REGEX.match("ம. ஆ. ஜூலீஎன் <[e-mail]>")
>>> <regex.Match object; span=(0, 44), match='ம. ஆ. ஜூலீஎன் <[e-mail]>'>

So my question would now be - should I submit a pull request with import regex as re to Poetry? Or would adding a dependency risk breaking things? Thanks!

@vlcinsky sure I understand. I just needed to get something done really quickly.

Retrieving Poetry metadata

# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.

It will add the `poetry` command to Poetry's bin directory, located at:

$HOME/.poetry/bin

This path will then be added to your `PATH` environment variable by
modifying the profile file located at:

$HOME/.profile

You can uninstall at any time by executing this script with the --uninstall option,
and these changes will be reverted.

Installing version: 1.1.4
  - Downloading poetry-1.1.4-linux.tar.gz (57.03MB)

Poetry (1.1.4) is installed now. Great!

To get started you need Poetry's bin directory ($HOME/.poetry/bin) in your `PATH`
environment variable. Next time you log in this will be done
automatically.

To configure your current shell run `source $HOME/.poetry/env`
