Welcome to libbash FAQ page!

This page contains list of most known problems you may run into while developing a bash libarary.

The Questions

Question 1

How can I use a local variable as an array ?

Answer 1

When using a local variable, the line:

local VAR_NAME 

is used as a declaration of VAR_NAME. Unless implicitly mentioned otherwise, declaire creates a `regular' variable. Because of that, in order to use a local array you must implicitly declaire that it is an array:

declaire -a local ARR_NAME 

Question 2

Using hashstash (3) hashes, How do I declare a local hash?

Answer 2

You can't. The reason for that is that every hash created by hashstash is created as a hashstash internal variable. I.e. the actual name of the hash is not HASHNAME but __hashstash_HASHNAME.
