If you use a checkbox then can I also use the columns box? What if I don't, making the columns box empty, which in the current code would prevent get_collections() from being called. One problem with that is the interplay between the contents of the columns box and metadata management. I would normally add a checkbox to enable the feature and that would be enough. But, I'm not a fan of adding what is effectively a special column name. But, allowing both is probably the most compatible.

My original thought was either a template or the current list of columns. I've gone back and forth over exactly how to do this. It permits generating collections from columns in addition to the template.This is important when dealing with device_collections. It doesn't interfere with metadata management because in get_collections it acts like a column.There are two reasons I chose to add 'template' as a collections attribute instead of making it either attributes or template but not both: Return generate_values('', $#dthtags, ',', 'DTH_Tags: ', '')įiHere is a screenshot of the configuration tab. Res = generate_values(res, $#cbhtags, ',', 'CBHTags: ', '') Res = generate_values('', $authors, '&', 'Authors: ', 1) If letters then f = substr(f, 0, letters) fi For my wife's it generates one set of names from her personal tags.ĭef generate_values(previous, col_val, sep, prefix, letters): For my Libra 2 the template generates two sets of collection names, one set for my personal tags all prefixed with 'CBHTags: ', and another set of the author's name's first letter prefixed by 'Authors: '. All the hard work is done in the generate_values() function. It supports both my wife's and my Libra 2s. The template returns a list of collection names separated by (the same separator used in template searches). The driver invokes the template when looping through the collection attributes. It can be the only attribute if you wish. I have an implementation that permits one to add 'template' to the list of collection attributes. After a month or so of using my original system I came to agree with you. You felt that a better approach would be to use a template to generate the names, not rewrite the names. Last we talked about this I was playing with using a template to optionally rewrite collection names.
