[dependabot-preview]

Bumps environs from 4.1.0 to 6.1.0.

Changelog

Sourced from environs's changelog.

6.1.0 (2019-11-03)

Features:

• Add deferred validation via the eager parameter and env.seal() (#56).
  Thanks robertlagrant for the suggestion.

Other changes:

• Test against Python 3.8 (#108).

6.0.0 (2019-09-22)

Features:

• Default parser methods are now defined as bound methods.
  This enables static analysis features, e.g. autocomplete (#103).
  Thanks rugleb for the suggestion.
  Backwards-incompatible: As a result of this change, adding a parser name that is the same as an existing method
  will result in an error being raised.

import environs

env = environs.Env()

# Below conflicts with built-in `url` method.
# In <6.0.0, this would override the built-in method.
# In >=6.0.0, this raises an error:
#   environs.ParserConflictError: Env already has a method with name 'url'. Use a different name.
@env.parser_for("url")
def https_url(value):
    return "https://" + value

Bug fixes:

• Fix error message for prefixed variables (#102).
  Thanks AGeekInside for reporting.

Other changes:

• Backwards-incompatible: Rename Env.__parser_map__ to Env.__custom_parsers__.

5.2.1 (2019-08-08)

Bug fixes:

• Fix behavior when recursively searching for a specified file
  (#96).
