null string in tags

[takaxp]

Hi.

I just find that null string tags are exported to markdowns. Is this intended?

[kaushalmodi]

Yes, this is a bug. Though, I am curious, how did you end up with this bug? Why set empty strings for tags? :)

[takaxp]

I just put "" into EXPORT_HUGO_TAGS :)

:EXPORT_HUGO_TAGS: "" "hoge"

It was happened accidentally while refactoring my tags, but the post was also exported by the auto-exporter. After publishing my new posts including the post with null tag, then I realized it an empty tag was appeared in the tag could in my Hugo blog.

@takaxp The fix was easy. I think most of your bug reports got resolved by using just org-string-nw-p :P You are really good at finding those corner cases! 👍

[takaxp]

Interesting, and thanks! 👍

@takaxp Actually I am thinking of reverting that commit and instead throw a user-error if "" tag is found.

I don't see a reason to commit "" to the source Org files permanently. As you said, they happened by mistake, and should be fixed.

That commit just masked the user mistake. But by making this an error, that can be fixed.

[takaxp]

That's good idea. For me, user-error will be able to provide kind suggestion.

[kaushalmodi]

Thanks for the quick response, I'll make the user-error display the name of the front-matter having empty string element.

[takaxp]

That's very useful because actually it took some time to find the entry with null field. So if the user-error provides information about the mistakes, that's really useful.

@takaxp OK, let me know how it goes after updating to the latest master.

Verified. Works well. Thank you so much :)
