Python script to rename your Roam daily notes to match Noteplan Calendar format.

roam_daily_to_noteplan.py

'''

This is a script that tries to convert Roam Daily Notes to Noteplan Calendar
Notes. All it does is find files in the current directory that have a name
matching the Roam Daily Notes format (e.g. "August 8th, 2020.md"), rename them
to the Noteplan Calendar Notes format (YYYYMMDD, e.g. "20200808.md") and move
them into a subfolder of the current directory: 'renamed_daily_notes'.


I recommend you read this blog post before going any further: 
https://axle.design/why-and-how-to-use-obsidian-and-noteplan-together. 
It's not specifically about moving from Roam to Noteplan, but it provides a bunch
of helpful info about how Noteplan works with md files and how Noteplan's sync
and stuff works. Definitely read it!


NOTES:
- PLEASE PLEASE MAKE A BACKUP OF YOUR NOTEPLAN NOTES BEFORE YOU DO ANYTHING ELSE.
- THIS IS A FREE AMATEUR-MADE SCRIPT, PLEASE MAKE SURE YOU KNOW WHAT YOU'RE DOING BEFORE
  RUNNING IT. I OFFER NO GUARANTEES AABOUT ITS SAFETY OR RELIABILITY WHATSOEVER.


## Steps to use:

1. Download a Markdown export of your Roam database.
    a. In Roam, click the three dots on the top right
    b. Click "Export All", and a little popup will appear.
    c. Choose "Export Format" -> "Markdown", and click "Export All"
2. Unzip the folder. (It will download as a zip file; unzip it.)
3. Copy this script into the unzipped folder.
4. Open your Terminal and navigate to that unzipped Roam export folder. You
   will probably do this by typing "cd Downloads/[roam folder name]", but it
   depends on your computer.
5. Run the script! Just type: "python ./roam_to_noteplan.py", hit Enter, and
   follow the prompts.
6. Now your Noteplan Calendar Notes are in a sub-directory titled
   "renamed_daily_notes."
7. Delete the script file, you're all done!



## Importing files into Noteplan:

NOTE:
- IF YOU ARE STARTING FULLY FROM SCRATCH WITH NOTEPLAN, you can just copy the
contents of renamed_daily_notes into your Noteplan/Calendar folder,
and replace any files currently there. Then you can copy the rest of your Roam 
export into the Noteplan/Notes folder.
- If you already have some Noteplan Calendar Notes, YOU HAVE TO BE CAREFUL!
You don't want to overwrite your Noteplan stuff with your Roam stuff.
You'll have to manually reconcile things.

With that out of the way,  in order to import these into Noteplan, you'll want to check what 
sync technique you use...

If you use Cloudkit, your Noteplan notes
will be in `~/Library/Containers/co.noteplan.NotePlan3/Data/Library/Application Support/co.noteplan.NotePlan3/`
and you'll want to copy your converted Calendar Notes into the "Calendar"
subfolder: `~/Library/Containers/co.noteplan.NotePlan3/Data/Library/Application Support/co.noteplan.NotePlan3/Calendar`)

If you use anything else, you should be able to go to Noteplan 3 > Preferences
> Sync > [Sync technique] > Advanced > [Open folder, or something like that].

When you find your Noteplan folder, you can just copy your converted daily
notes into the Calendar subfolder, and the rest of your notes into the Notes
subfolder.

To reiterate the warning above,
   IF YOU WROTE IN BOTH ROAM AND NOTEPLAN ON A GIVEN DATE, YOU DONT WANT TO JUST
   OVERWRITE YOUR NOTEPLAN FILE WITH YOUR EXPORTED ROAM FILE... THIS SCRIPT
   WILL RENAME YOUR ROAM FILE TO MATCH THE NOTEPLAN FILE SO THEY WILL CONFLICT 
   WITH EACH OTHER... YOU HAVE TO MANUALLY COMBINE THE TWO FILES!

Thanks for sharing this!

@Rainymood no prob, so glad it was useful to someone!

This is the error I am getting, a folder is created for Renamed Notes, but it is empty

@yashodhankhare I think you may be using Python 2.7, and you need to use Python 3.2 or later (see “Changed in version 3.2” here).

Depending on your setup, you may be able to just call “python3” instead of “python”. If that doesn’t work, and you’re not sure how to use a different Python version, this seems like a reasonable introduction.

@yashodhankhare If you’re on a recent Mac, you should just be able to type “python3” instead of “python” on the command line, per my last comment. If that doesn’t work, please follow the tutorial I linked in my last comment.
