ascii_printable_visible

[jjb]

A method to generate from more or less the entire "typable" space.

This is the sort of thing I might use if I need to generate a random password for a user.

I tried to name it in order of increasing specificity. maybe the name should be nicer to type.

I think the regex in the test is correct.

I implemented it using alphanumeric instead of choose to avoid repeating code.

Let me know what you think!

@nobu @hsbt what do you think?

What do you intend by “printable visible”?
Doesn’t “visible” imply “printable”?

[nobu]

Random::Formatter#alphanumeric was designed so that any character set can be used as an option..
To be honest, I don't think it's a good idea to add methods for every possible character set.

BTW, I think !..~ is called a "graph" in C and POSIX terminology.

“Printable” comes from the ascii spec

here I include everything in that range except for white space

happy to use a different name!

sure - my proposal is just an idea for what is a common need for me and I thought maybe others. To generate a secret string with letters, numbers, and symbols. For example to meet password requirements.
