awesome script!!
one small note: sometimes filenames tend be over the allowed length (depending on the post), so slug in line 143 may need to be cut to an appropriate length

I had the same problem as @johdax, I added this block right below line 144:

# shorten slug if too long
if slug.length >= 80
  slug = slug[0, 80]
end

Apologies if I'm missing something, but while the description says this will "import tumblr posts into local markdown posts" my output is a series of HTML files.
