Monitor ZIM files from a user-chosen directory

[juuz0]

Some people like to put all of their files at a different directory (usually case with windows users).
If I'm not mistaken, the current way right now is to open each zim file so it adds that in the local library.

A good way could be to :
Add an option in Settings to import all zim files from a directory (user chooses dialog box) [check the load local zim files option]

In a way, this can also simplify https://github.com/kiwix/kiwix-desktop/wiki/Kiwix-desktop-on-an-USB-Drive-(Portable-version)

This is a follow-up of #644 (comment)

Does not sound a bad idea... but need to be confirmed first. I need to think more about it.

[kelson42]

For the moment I think this is actually a good idea and would allow (like written in the description) to solve #461 as well. For that we should have the following workflow:

• Per default the "local directory"(we need probably to rething a bit the naming/wording) would be the one of the binary.
• I someone changes it, then it looks to another place
• There is a button reset/browse like for the download directory.

[kelson42]

Regarding the naming, one idea would be "Monitor Directory". We could add a hint on it to help users to understand what this is about.

@juuz0 With @mgautierfr we agree to do so. I propose to call is « Monitored Directory ». Per default it should be not defined. Probably a tooltip or a small question mark badge should be added, proposing a simgle sentence explanation of what it is. We should wait that libkiwix proposed all the primitives to live update the library before first working on it.

Noted 👍

[kelson42]

@juuz0 kiwix/libkiwix#636 has been merged, so libkiwix should provide the necessary to implement this feature properly, ie.:

• dedicated settings entry
• Check periodically the directory for new files (non recursively, only first level)
• Add new files to library and ask refresh (to remove automatically the ZIM files which have been removed)

[juuz0]

@kelson42 Thanks 👍 Will do it

@kelson42
How do the changes in kiwix/libkiwix#636 work?
The library isnt reloading for me in kiwix-serve :/
Steps I followed:

• Downloaded a small zim file from the wiki
• Put it in download directory
• Start kiwix-serve

The book wasnt visible

[kelson42]

@juuz0 It should work that way:

• configure directory to monitor in kiwix-desktop
• monitor directory changes in kiwix-desktop (add/remove/update of zim files)
• if change detected, update library with libkiwix (not sure exactly how to do, but look how it is done with kiwix-serve news library monitoring option).

Have you done the first 2 bullets laready?

[juuz0]

@kelson42 Yes, I've done the first two.
Only a trivial amount is remaining - to reload the library.
That should be easy since it's already done in libkiwix and kiwix serve (which somehow isn't working for me - library doesn't reload, I'll check again)
