There is a new release of the NanoBlogger Gallery plugin. The previous version had a problem when run in Bash versions below 3.1. There are some differences when initializing arrays from a ’string’ using $IFS.

In Bash 3.1 you can do this:

1
2
3
4
5
6
7
8

#!/bin/bash
 
a="1.2.3"
IFS='.'
declare -a arr=( $a )
echo "${#arr[@]}"
 
# Outputs 3 in version 3.1 and 1 in version 3.0

But if you instead do this then it works in both versions:

1
2
3
4
5
6
7
8
9

#!/bin/bash
 
a="1.2.3"
IFS='.'
declare -a arr
eval "arr=( $a )"
echo "${#arr[@]}"
 
# Outputs 3 in version 3.1 and 3.0

So hopefully the Gallery plug-in is better prepared for the real world :). Thanks to Chris Gratham for helping me out with this.

The new version can be downloaded here.
