# This will give all the ICSE2015/2016 papers filenames extracted from the titles of the PDF metadata,
# and put them in a folder on your desktop. It's been tested on OSX and depends on wget and pdfinfo,
# available via the macports xpdf package on pre-Yosemite OSX, and here for Yosemite users:
#
# ftp://ftp.foolabs.com/pub/xpdf/xpdfbin-mac-3.04.tar.gz
#
# It's a manual install, unfortunately, but I trust you're geared up for that.
#
# The username and password are available from these public-facing pdfs:
# http://atlantis.isti.cnr.it/ICSE2015ProgramBrochureOnLineVersion.pdf (2015 - icse15/conf15)
# http://2016.icse.cs.txstate.edu/static/downloads/conference-brochure.pdf (2016 - icse16/conf16)
# The "grep [ab]" part is what filters out the papers from schedules, posters and other PDFs, which
# may or may not have Title metadata. Because someone thought "we'll use the fifth character in the
# filename as meaningful metadata. That is entirely sane and reasonable."
#
# This script was first written in 2015, and has been updated for ICSE 2016 mostly by replacing all
# instances of "15" with "16".
#
# I wish I was joking.
wget -c --user=icse16 --password=conf16 http://conferences.computer.org/icse/2016/content/icsefull.zip && unzip -d icsefull icsefull.zip
cd icsefull/content/papers/
mkdir sanity && cd sanity
for x in `ls ../*.pdf | grep [ab]`; do cp $x "`pdfinfo -meta $x | grep "^Title:" | sed 's/Title: //' | sed 's/\//-/g'`.pdf" ; done

Thanks for this!

fwiw - my unzip doesn't create folders on a per-zip file, and just dumps it in place, so I had to remove icsefull/ folder portion of line 10 (UnZip 5.52 of 28 February 2005, by Info-ZIP.)

Also, I didn't have xpdf installed, so was getting a -bash: pdfinfo: command not found error, which I solved via brew install homebrew/x11/xpdf

Finally, the renaming on line 12 ran with two errors (sed: RE error: illegal byte sequence) - and I think not all files of interest have the PDF meta information. I have 776 files with sane names, but there are more files than that with the crazy names:

papers$ ls *.pdf | grep [ab] | wc -l
     856

Thanks! I'll test it and update.

Testing, I see that the only papers that fail that process are either keynotes or author's lists. We're good.

Also, I've added a command-line flag to that unzip command that solves the unzip thing, sorry about that.

thanks for checking, 🍰 for you!

(also, one last thing, given that it's a 400M file, might be worth it to add the -c flag to wget, so you can resume in case of disconnect, ctrl-c, or whatever)

Here's an alternative which..:

  1. adds a dependency on fuse-zip so the archive never needs to be decompressed (except when actually reading a PDF from within it), avoiding the file size tripling of the original (zip + decompressed + cp'd);
  2. adds a few sanity checks;
  3. roughly triples the script size (well, you can't hug all the cats)
