New 1.8 .rm format

[Evidlo]

As of update 1.8, the .rm files are in a new format.

It looks like instead of each file being indexed by the page number, the pages are now assigned a random UUID.

012f4a15-8cdb-4d44-aa02-05fd911873e6-metadata.json

dec625e0-8c4a-4cba-8143-bf8c8b9b0d86.rm

Additionally, the accompanying .json files contain layer information:

[root@remarkable 6b96d778-b6f5-458e-9b7d-649689706f37] cat 012f4a15-8cdb-4d44-aa02-05fd911873e6-metadata.json 
{
    "layers": [
        {
            "name": "Layer 1"
        }
    ]
}

Page order can be inferred from the .content file

Only pages that have been annotated have .rm files.

Thanks for the heads-up!
Do you (or anybody else) want to update the .rm file handling and add some meta-data support for the JSON files (r/w)?

I would propose to use nlohmann/json for this #19.

[gitbock]

Same for me. Was looking forward to use the tool. Compiled fine on my aarch64. Then I realized that it will not read the notebook because of the uuid names :(

Isn't it possible to do give the entire filename on command line and let the page be converted?

Running 2.0.2.0 on my remarkable.

I currently don't have time for the meta-data update that is needed here, but PRs are very welcome.

Just to follow on here, it seems that as of firmware v2.14.1.866 (or possibly before), these files are now version 5, so simply accessing according to the JSON isn't enough, and there may be more significant changes to consider... 😢 Happy to provide a full set of files on request.

Unfortunately I don't have the time to get into this right now, but I'll keep it in mind - I've only just got my RM2 and was hopeful this would work!
