List of examples about envvars

[flemay]

Currently it would not be possible. example can be passed to the command envfile which generates a .env file with the example values. :)

What I think would be best is to have a list of accepted values. What do you think @aarongorka ?

[aarongorka]

My example is probably not very good, I was thinking more of very dissimilar examples but not necessarily a list of accepted values. An application I am working with accepts both files and directories as input so I wanted to have both dir/file.yml and dir/ as examples.

Some options I thought of;

1. Generate the .env.example from the 1st item in the examples list (too unintuitive/magic)
2. Have two separate fields (example and examples? default and examples?)
3. Just put my examples in the desc field

If 2. is not a good idea I will just do 3. and we can close this issue.

1. Too magic hehe
2. default would be confusing as in people may think that it would be that value if none is provided whereas I use example values to generate .env file only if you pass example. and having example along with examples will be confusing too because both will be for different purpose while 1 being just the plural of the other.
3. desc would be a good place where to start.

That being said, wonder if there is another way to generate the example or maybe generating the example file is not required?
