Load environment variables from the specified file
Load variables defined in the given file, as environment variables.
load_dot_env(file = ".env")
file |
The name of the file to use. |
The file is parsed line by line, and line is expected to have one of the following formats:
VARIABLE=value VARIABLE2="quoted value" VARIABLE3='another quoted variable' # Comment line export EXPORTED="exported variable" export EXPORTED2=another
In more details:
A leading export is ignored, to keep the file
compatible with Unix shells.
No whitespace is allowed right before or after the equal sign, again, to promote compatilibity with Unix shells.
No multi-line variables are supported currently. The file is strictly parsed line by line.
Unlike for Unix shells, unquoted values are not terminated by whitespace.
Comments start with #, without any leading
whitespace. You cannot mix variable definitions and
comments in the same line.
Empty lines (containing whitespace only) are ignored.
It is suggested to keep the file in a form that is parsed the
same way with dotenv and bash (or other shells).
