CreationMonth - A script column to sort and group items by their month of creation. ("month of creation" - is that correct english?)
This column is the first to come in two languages. English is the default, german kicks in automatically if you use the german language in DO. This script shall be a test as well, if multilanguage-addins are a good thing to have or will lead to yet unforeseen issues.
Description:
This column is useful, if you're browsing a larger photo collection (flatview maybe), which covers several years and the only pictures you're interested in shall have been taken in any december e.g. If you sort/group on images, the exif-datetaken or exif-shootingtime always takes precedence over the file-creation date.
You can find images related to christmas/winter/summer/automn/spring more easily with this. I'm currently preparing a calendar to print, so finding images fitting a specific season is the task! o)
Demo:
The images below were taken in different years, but they come together in a group "December", because all of them were taken in december.
Installation:
To install the column, download the *.js.txt file below and drag it to Preferences / Toolbars / Scripts.
After that, right click any listers column header and add the column from the "script" submenu.
Notes:
Sooner or later this column will/should move into the CustomGrouping-Addin:
Make sure to add your rare image file extension to the script configuration "Extensions" item.
Download:
Download the latest file below, then drag it to the list under Preferences / Toolbars / Scripts.
Thanks! o) So you do picture-calendars as well from time to time? o)
Maybe DO could have builtin support for finding specific days/weeks/months regardless of the year. Because the windows search also did not help while trying to find photos taken in a specific month. At least I managed to get something out of it with the following query, but that's not really handy to use, this also needs translation to the german query keyword syntax if your windows is a german edition, how insane is that? Wonder when spanish SQL sees the light. o)
Example-query to find all images taken in december from 2009 to 2012:
date:December2009 OR date:December2010 OR date:December2011 OR date:December2012 OR date:December2012
But unfortunately I have a performance-issue with evaluating the month-value.
For a folder with ~2000 files it takes about 12 secs for DOpus to add all month-column-values.
=> very sluggish
The reason is the access of item-metadata.
Imho, for filetypes <> image this would not be necessary.
Maybe there are other ways to identify a file as an image? E.g. by extension?
Well, yes identifying by extension would be possible, but then you also need to avoid to look at the exif-dates within the pictures to speed things up. Maybe I add another column to this script, that does not try to detect images at all and just goes for the regular filesystem creation timestamp, then it's as fast as can be.
You have misunderstood me.
For images it would not be possible to speed it up because you need those date-information.
But for non-images you do not need any of those metadata-information.
Sth. like this (would not work in DO, because vector != array....)
var imageExt = ['.jpg', '.jpeg', '.tiff', '.tif', '.png', '.gif', '.bmp'];
if (imageExt.indexOf(data.item.ext) > -1) {
if (data.item.metadata.image_text.datetaken != undefined){
creationDate = new Date(data.item.metadata.image.datetaken);
}
if (data.item.metadata.image_text.shootingtime != undefined){
creationDate = new Date(data.item.metadata.image.shootingtime);
}
}
if (creationDate === null){
creationDate = new Date(data.item.create);
}
var month = creationDate.getMonth();
data.value = month+1;
}
That should work (if it works outside of Opus), if you mean the first two lines. You can use JScript vectors arrays in JScript code, Opus just doesn't use them for its own APIs as they behave inconsistently between languages.
speed improvement (when there are alot of non-image files)
@dinkel
An array does not have a .indexOf() method. In recent javascript, there is contains(), but that's also not part of JScript. If you like to stick with an array for these kind of checks, use something like myArr.join("").indexOf(".xyz"). I'd use a string right from the start though.
Yes, that's right, but wouldn't work in vbscript btw..
VBscript brainlessly always evaluates all of the condiditions and would not prevent to "touch" data.item.metadata in this case.
