Issue with env showing in help

[scriptanium]

Hello,

As you can see on this picture and told in the documentation, my env var are put in the struct tags of the args struct with default values.

And here you can see that for any reason env var are also shown as arguments sadly.

It did not do this previously but my project evolved (but the library always has been in version 1.4.3 and this part kept untouched) and so I don't understand why there is a problem now and how to fix it.

I don't know if I missed something or if it is finally normal, but if it is not, maybe I should try to work on a PR, but I am pretty overloaded, so sadly (for me) I may not be able to try to fix this in the short term.

Is it that you wanted the environment variable to not show up in the help text?

[scriptanium]

Yes (and not to be considered as arguments with --)
I still find your struct tags configuration even of ENV very practical.
If it not possible I may try to just manually use os.GetEnv.

I'm not completely clear on what you mean by "not to be considered as arguments with --".

Can you show me how you would want the help output to appear, for the example from your original comment above? It would be most helpful if you could copy and paste the output from your original comment and edit it to how you would want it to appear.

It is :

Usage: schematic_rest [--port PORT] [--store STORE] [--size_max SIZE_MAX] [--db DB] [--schem_dir SCHEM_DIR] [--log_level LOG_LEVEL]

Options:
  --port PORT [default: 80, env: PORT]
  --store STORE [default: /app/data, env: STORE]
  --size_max SIZE_MAX [default: 32M, env: SIZE_MAX]
  --db DB [default: database.db, env: DB]
  --schem_dir SCHEM_DIR [default: schemata, env: SCHEM_DIR]
  --log_level LOG_LEVEL [default: INFO, env: LOG_LEVEL]
  --help, -h             display this help and exit
  --version              display version and exit

And it needs to be :

v0.0.0
Usage: schematic_rest

Options:
  --help, -h             display this help and exit
  --version              display version and exit

While still reading the env variables in the code.

Like if environment variable are not specified as command line argument with short or long options ("-short or --long") that no command line options are generated for them and nothing present in the help. (except wanted explicitely)
