Possibility to manipulate EPG title for recording schedule?

Wapsi

Is it possible to manipulate the title or other fields grabbed from the EPG for the recording schedules (so that the title is changed already for the upcoming schedule, not after the recording is finished)?

Example: If the program title in the EPG is "Foo Bar (18)", where that (18) is the age limit information. That's unnecessary in the recording title, especially if the title is used for subdirectories when arranging the recordings to different directories etc. I would like to remove that part by using regex or sed or similar, is that possible? In my country some channels are specifying even different age limit for different episodes, so the result is quite messy as there could be multiple subdirectories per the same show:
Foo Bar (16)
Foo Bar (18)
etc.

I searched this forum and Tvheadend documentation and found couple of interesting topics, but do not provide the answer for my question:
https://tvheadend.org/d/8530-remove-new-from-title-and-gaps-when-recording-movies
https://docs.tvheadend.org/documentation/development/pathname-substitution-strings-and-command-script-variables

If this isn't possible, do you think it could be something that can be tagged as feature request and put into the roadmap?

Creating recordings via Json API or HTSP you can use the "title" keyword to set the recording title to your liking.
https://docs.tvheadend.org/documentation/development/json-api/api-description/dvr#dvr-entry-create
https://docs.tvheadend.org/documentation/development/htsp/client-to-server-rpc-methods#adddvrentry
This would typically be from a script.
From the TVH Web GUI you can edit the title of a scheduled recording.

Thanks! That's actually good approach. I can create a Bash script that runs periodically via Cron, lists all the recordings and go thru them one by one and does the "sed'ing", and if the title changed during that, it will update that particular schedule title:

curl 'http://x.x.x.x:9981/tvheadend/api/idnode/save' \
  -X POST \
  -H 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8' \
  'node={
  "enabled": true,
  "disp_title": "UPDATED TITLE",
  "disp_extratext": "Original description",
  "channel": "xxx",
  "start": 1757165700,
  "stop": 1757167200,
  "start_extra": 0,
  "stop_extra": 0,
  "pri": 6,
  "config_name": "yyy",
  "removal": 0,
  "uuid": "zzz"
}'

Here is the solution I wrote for this. I run it by using Cron every 15 minutes:

#!/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

# Fetch JSON data and parse UUIDs and titles into an array of strings
# each string containing 'uuid title'
while IFS= read -r line; do
        uuids_and_titles+=("$line")
done < <(timeout 15 curl -s "http://127.0.0.1:9981/tvheadend/api/dvr/entry/grid_upcoming?limit=99999" | jq -r '.entries[] | "\(.uuid) \(.disp_title)"')

# Loop through the combined array and assign to separate arrays
for item in "${uuids_and_titles[@]}"; do
        # Split the string into uuid and title
        read -r uuid title <<< "$item"
        # Add to respective arrays
        uuids+=("$uuid")
        titles+=("$title")
done

# Loop through the array and perform the title update
# If the title matches the regex -> update the new title to Tvheadend scheduled recordings
for i in "${!uuids[@]}"; do
        # Defined filters:
        #  \(1[0-9]\)$| \([0-9]\)$ and  (1[0-9])$//;s/ ([0-9])$// -> Remove rating/age limit from the end of program title name (like: "title (7)" -> "title" or "title2 (18)" -> "title2")
        if echo "${titles[i]}" | egrep -q " \(1[0-9]\)$| \([0-9]\)$"; then
                newtitle=$(echo "${titles[i]}"|sed 's/ (1[0-9])$//;s/ ([0-9])$//'|sed 's|"|\\"|g')
                echo "Updating scheduled title: ${titles[i]} to $newtitle"
                dataurlencoded=$(echo '"uuid": "'${uuids[i]}'", "disp_title": "'$newtitle'"'|jq -sRr @uri)
                ret=$(timeout 10 curl -s "http://127.0.0.1:9981/intranet/app/tvheadend/api/idnode/save" -X POST -H "Content-Type: application/x-www-form-urlencoded; charset=UTF-8" --data-raw \
                'node={ '$dataurlencoded' }' 2>&1)
                if [ "$ret" == "{}" ]; then
                        echo "Title updated OK"
                else
                        echo "Title most probably not updated, Tvheadend returned: $ret"
                fi
        fi
done
