Collections

gobash introduces two key collections: List and Map. Both collections include a number of methods that can be convenient for everyday development.

In the example below, we use an instance of a List to keep URLs of several GitHub projects and then close each of those projects in a loop.

#!/bin/bash
. gobash/gobash

lst=$(List)
$lst add "https://github.com/apache/commons-math"
$lst add "https://github.com/apache/commons-io"

# Print length.
$lst len

# Clone each repo.
for (( i=0; i<$($lst len); i++)); do
        git clone $($lst get $i)
done

# Print the list.
$lst to_string

Note

Equality in gobash is done based on object identity. Future changes could consider using eq methods to check for equality (similar to other programming languages).
