Hi,

Sometimes we can not share .env file. However it would be useful if we could generate a .env.example from it which contains all the comments and keys name in it. For example, suppose .env has the following content,

# this is comment
API_SECRET_KEY=some-value

Then generated .env.example file has the following content,

# this is comment
API_SECRET_KEY=

It would be useful if a CLI command is provided for it.

Thanks

I'll work on this soon.

I just made a function that does this, but I still have to incorporate it into the cli. Will do it tonight.

Something cool about an .env.example file is that it can not only be used for human reference purposes, but also to facilitate an opt-in programmatic safety feature. The example file can be shipped with an application, then read at runtime and used to establish a list of the names of variables that must be defined. See the dotenv module in Deno's standard library: https://deno.land/[email protected]/dotenv#safe-mode

Update: Deno removed that feature :( denoland/std#5450
