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.

It has been tested on the for the following releases:

• 3.0
• 3.1
• 3.2
• 3.2.3
• 3.3 RC5

The major problem that needed to be fixed is that the plug-in uses standard NanoBlogger calls as often as possible. This means that the standard entry format can be used and even that (from version 3.3) the format field can be used to put markup into the entry.

Unfortunately the NanoBlogger API has changed a bit between versions. The call to read_metadata does not fill the same return variable in the versions mentioned above:

• $NB_Metadata for version 3.0 and 3.1
• $META_DATA for versions 3.2 and 3.2.3
• $METADATA for version 3.3

There was already a function in the plug-in to determine for two given version numbers which was the newer one because the parameters to read_metadata also needed to have $METADATA_CLOSETAG specified from version 3.3 and up if the entry’s body is requested. So the plug-in already had to choose between two different calls based on the NanoBlogger version.

But everything seems to be fixed for now. The new plug-in can be downloaded here.

• The new gallery plug-in can be downloaded here.
• The new code plug-in can be downloaded here.

Enjoy and if there are any questions or problems contact me.

This release will test if the plugin is running on Mac OS X and delete all picture files (*.jpg and *.png) starting with ._ in the current gallery directory.

The new version can be downloaded here.

Beware: This plugin has only be tested with versions 3.1 and 3.3 RC3 of NanoBlogger. If I have time I will try to test the plugin for other versions. But don’t let that stop you from doing the same and provide me with feedback :).

You can download it here.

You can get this release here

It is now in a quite usable state so I am sharing this with the rest of the world. Its usage is (hopefully) quite simple:

Usage

1. Install the plugin gallery.sh in the NanoBlogger plugin directory. The plugin can be downloaded here.
2. Create a directory named galleries in the NanoBlogger image directory. Any sub-directory of galleries will be considered a gallery.
3. Place the pictures (JPG or PNG format) in the sub-directory of galleries that you created.
4. Adjust the template main_index.htm to include the variable $NB_GalleryLinks
5. Run nb -u all.

The created gallery will get the title of the sub-directory in which the pictures are stored.

These are the basics. But the plugin also gives the possibility to:

• Prepend an introductory text
• Annotate arbitrary pictures

Prepend introductory text

Create a file named intro.txt in the place the pictures are stored using nb --draft intro.txt and treat it like you would treat a regular entry for NanoBlogger. The title you set in the entry will be the title for the gallery.

Annotate pictures

Create a file named annotations.txt and put a line for each picture you want annotated using the following format:

<picture file>,<annotation>

Picture file is the local file name of the picture. Do not include paths, just use the bare file name. Everything after the comma is then considered an annotation for the picture.

To make the gallery a bit more pleasant-looking adjust your website’s style sheet. You can use this as an example.
