In debug mode, show errors like:

[dotenv][DEBUG] did not match key and value when parsing line <n>:
[dotenv][DEBUG] did not match key and value when parsing line <n>: #<COMMENTED_LINE>

Sometimes we need to add empty lines to separate groups of variables, or comment some of them.
We don't want the debugger or the parser catch them.

if you want to influence "debug" behavior, I'd suggest moving closer there instead of possibly altering the parsing logic. if (debug && line.length && line[0] !== '#') might do it, although I have reservations about decreasing debug output.

Closing due to inactivity. Feel free to reopen but I would like to have more discussion about decreasing debug output.

[Compare Source](motdotla/dotenv@v14.3.2...v15.0.0)

`v15.0.0` is a major new release with some important breaking changes.

##### Added

-   *Breaking:* Multiline parsing support (just works. no need for the flag.)

##### Changed

-   *Breaking:* `#` marks the beginning of a comment (UNLESS the value is wrapped in quotes. Please update your `.env` files to wrap in quotes any values containing `#`. For example: `SECRET_HASH="something-with-a-#-hash"`).

..Understandably, (as some teams have noted) this is tedious to do across the entire team. To make it less tedious, we recommend using [dotenv cli](https://github.com/dotenv-org/cli) going forward. It's an optional plugin that will keep your `.env` files in sync between machines, environments, or team members.

##### Removed

-   *Breaking:* Remove multiline option (just works out of the box now. no need for the flag.)

### [`v14.3.2`](https://github.com/motdotla/dotenv/blob/HEAD/CHANGELOG.md#&#8203;1432-httpsgithubcommotdotladotenvcomparev1431v1432-2022-01-25)
