This package loads the variables defined in the
.env file in the
current working directory (as reported by
getwd()), and sets them as
This happens automatically when the
dotenv package is loaded, so the
typical use-case is to just put a
library(dotenv) call at the
beginning of your R script.
dotenv::load_dot_env() call can be used to load
variables from arbitrary files.
You can simply put
at the beginning of your script, to load the environment variables
.env in the current working directory.
.env 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
bash (or other shells).
Any scripts or data that you put into this service are public.
