Save Template, is appending one tag to a filename possible?

[chrisric]

Hi,

I've searched this forum and Google, I think I'm more lost now

I want to create a save template that will append one specific tag to the filename if that tag is linked to a book. All other books without tag "xyz" will not have this filename changed.

Default: {author_sort}/{title}/{title} - {authors}

Obvious: {author_sort}/{title}/{title} - {authors} - {tags}
This lists ALL tags though...

Is there a way to parse the tags field?

Thanks.

Don't remember about specific tags in SFM. But this will list the first tag alphabetically and also get rid of an extra '-' when there's no tag.

{tags:sublist(0,1,&)| - |}

Thanks ownedbycats.

Using {tags:sublist(0,1,&)| - |} produces the same result as {tags}

I searched "Reference for all built-in template language function" and found nothing specific to tags that might work. Of course, I have no idea if any of the other functions may work.

I guess I could save the file with {tags} and use an external script to rename the file. I'd prefer that being a last resort though.

Read up on the list functions. They all work on tags.

The separator for tags is a comma, not an ampersand. As said in Using functions in templates - Single Function Mode (SFM), you enter a literal comma using \,

{tags:sublist(0,1,\,)}

The following template in Template Program Mode (TPM), is easier to understand (for me at least):

{tags:'sublist($, 0, 1, ',')'| - |}

However, you appear to be asking to test for the existence of a particular tag. That can be done by embedding General Program Mode (GPM) into TPM

{tags:'if '^xyz$' inlist $tags then 'xzy' fi'| - |}

If for some reason you don't want to embed GPM then this "pure" TPM template does it:

{tags:'in_list($, ',', '^xyz$', 'xyz', '')'| - |}

wow, thanks chaley.

I used the GPM version, I can even understand it once you spelled it out for me. I also tried the TPM version, they both work perfectly.

I really appreciate the help.

Cheers,

Oops, sorry - I copied the sublist from an author_sort and forgot to change the separator.
