Programatically trigger library scan

neuraltoxin · 09-06-2022, 11:01 PM

Hi all,
I'm the author of https://kobli.me and I recently released a version that allows users to download an epub from Google Drive to the device over Wifi.

The download works great but the library refresh is somewhat flaky. Here's the code I have to do the library refresh. It works sometimes but not others:

Lib=/mnt/onboard/.add/koblime/library
SD=/mnt/sd/koblime

mountpoint -q "$SD"
if [ $? -ne 0 ]; then
mount --bind "$Lib" "$SD"
fi
echo sd add /dev/mmcblk1p1 >> /tmp/nickel-hardware-status

Perhaps I need a sleep after the mount. Thanks in advance for any help

PS: I am not actually using a bash script. My app is written in Go and cross-compiled to arm7 but it's essentially doing the above...

If the user has NickelMenu installed, you can trigger a book import using:

Code:

menu_item : <location> : Import books : nickel_misc : rescan_books_full

Replace <location> with main, library, etc. corresponding to where you want to see the menu item.

I've been looking at the NM code and it looks like I can make calls into libnickel.so to trigger a sync. Thanks! I'm on the right track.

I've responded to your email, basically:

- You need to call libnickel from within; a separate process won't work.
- Alternatively, you can use Sherman's NickelDBus along with godbus or simply calling qndb with exec.Cmd;
- or you can write a custom one with NickelHook which listens over DBus, a Unix socket or SysV IPC.
