Script details

1. Save the JSON result of the query in a temporary file /tmp/res.json, HTML recoded for the accented characters

curl -s --data "start=${day}&end=${day}&resType=103&calView=agendaDay&federationIds[]=${tdlst[$td]}" https://edt.uvsq.fr/Home/GetCalendarData | recode html > /tmp/res.json

2. Sort the day's sessions by start time and start a while loop in the sessions array

jq -c 'sort_by(.start)|.[]' "/tmp/res.json" | while read i; do
  # ...
done

3. Parse and format the datetime objects to HH:MM

deb=`echo "${i}" | jq -c ".start" | sed -e 's/^"//' -e 's/"$//'`; deb=$(date --date=${deb} "+%Hh%M");
    end=`echo "${i}" | jq -c ".end" | sed -e 's/^"//' -e 's/"$//'`; end=$(date --date=${end} "+%Hh%M");

4. Parse and format the description field to extract the course name, room, type and group

desc=${desc//rn/}; desc=${desc//\"/}; # Removal of residual characters
IFS='<br />'; splitted=($desc); unset IFS; # Split the string into an array object

5. Cut to format the course name without the duplicate course code

mod=`echo ${splitted[2]}`; mod=`echo ${mod} | cut -c 3-$((${#mod}-11))`

6. Format and prints the schedule of the day's sessions

echo -e "\n\033[33;01m 📆 EDT du ${day} — TD${2:-1}\033[0m\n"
echo -e "\033[2m$deb — $end\033[0m\n\033[37;1m${mod}\033[0m\n| ${splitted[0]}\n| ${splitted[1]}\n"
