# what shells actually do.
|

#
|
|
# In particular, we can't use Shellwords::escape because it outputs a

|
# non-quotable string, while Dotenv requires `#` to always be in quoted
|
|
# strings.
|
|
#
|
|
# Therefore, we need to write our own escape code…
|
|
# Dotenv's parser has a *lot* of edge cases, and I think not every
|
|
# ASCII string can even be represented into something Dotenv can parse,
|
|
# so this is a best effort thing.
|
|
#
|
|
# In particular, strings with all the following probably cannot be
|
|
# escaped:
|
|
# - `#`, or ends with spaces, which requires some form of quoting (simply escaping won't work)
|
|
# - `'` (single quote), preventing us from single-quoting
|
|
# - `\` followed by either `r` or `n`
