# How to extract a list of Youtube links from a Facebook discussion thread and generate a playlist
# ------------------------------------------------------------------------------------------------
# By Doron Adler, @Norod78 
#
# Open the relevant comment thread in Facebook by tapping on the time next to the privacy indicator
# Save the relevant comment thread locally as a single “HTML only” file, call it "noalp.htm"
# Open your bash command line terminal, cd to the folder where you saved noalp.htm and paste the following:

grep -o -e 'https%3A%2F%2F\S*' "noalp.htm" > urlencoded.txt
cat ./urlencoded.txt | perl -pe 's/\%(\w\w)/chr hex $1/ge' > ./urldecoded.txt
cat ./urldecoded.txt | cut -f 1 -d ";" | cut -f 1 -d "&" | grep youtu |   sed 's/&amp//g' | sort | uniq > youtu.txt 

# The file youtu.txt contains a list of all Youtube links from that thread
# Now let's make a Playlist, based on these instructions: https://webapps.stackexchange.com/a/106340
# paste the following:
linkList=$(grep -o 'v=.*' youtu.txt | cut -f2 -d"="| tr '\n' ',')
linkList2=$(grep 'youtu.be' youtu.txt | cut -f 1 -d "?" | cut -f4 -d"/" | tr '\n' ',')
playlistURL="http://www.youtube.com/watch_videos?video_ids=$linkList$linkList2"
echo "You can already enjoy your playlist at $playlistURL"
echo "However, there are a few more steps to make it propper"
open "$playlistURL"

# Now comes the part where you make this into a sharable public playlist
# Go to the playlist URL that your browser went to after you opened the generated
# playlist. It should look something like
# https://www.youtube.com/watch?v=[First video]&list=[PLAYLIST ID]
# Edit the link so it would look like this:
# https://www.youtube.com/playlist?list=[PLAYLIST ID]&disable_polymer=true
# Press the three dots to the right of the playlist title, and then select "Add all to..." 
# Add the videos to your own playlist.
