Live Stock Monitor
Friday, 27 July 2018
|
Today, a small Python script to track live stock exchanges. It fetch data from boursorama website and format it for "Generic Monitor" XFCE applet which allows to display result of a command line script. Just setup the path of this script in genmon properties and set the delay to 60s (to avoid flooding website).

Get stock code id from website URL (last part). A file version is available here.
I added another part to get email count from gmail. It relies on a bash script that fetches RSS feeds when data is wrote in the FIFO.
Body of the script :
#!/bin/bash
USER='soutade'
while [ 1 ] ; do
echo -n "Please enter gmail account password : "
read -s password
echo ""
echo -n "Confirm password : "
read -s password2
echo ""
if [ "$password" != "$password2" ] ; then
echo -e "Passwords doesn't match !!\n"
continue
fi
break
done
pipew="/tmp/gmail-pipe-w"
piper="/tmp/gmail-pipe-r"
rm -f $pipew $piper
mkfifo $pipew $piper
while [ 1 ] ; do
read line < $pipew
feeds=`curl -u "$USER:$password" --silent "https://mail.google.com/mail/feed/atom"`
echo $feeds | sed s/.*\<fullcount\>//g | sed s/\<\\/fullcount\>.*//g > $piper
done
You can hardcode password in the script, but I don't like having my password in clear on the harddrive. A file version is available here.
