# The namespace regex is used in Javascript to validate usernames in the "Register" form. However, Javascript
# does not support the negative lookbehind assertion (?<!) that disallows usernames ending in `.git` and `.atom`.
# Since this is a non-trivial problem to solve in Javascript (heavily complicate the regex, modify view code to
# allow non-regex validatiions, etc), `NAMESPACE_REGEX_STR_JS` serves as a Javascript-compatible version of
# `NAMESPACE_REGEX_STR`, with the negative lookbehind assertion removed. This means that the client-side validation
# will pass for usernames ending in `.atom` and `.git`, but will be caught by the server-side validation.
