Lua: How to store project specific script data (tables)?

[spk77]

What would be the best way to store project specific Lua script data, especially tables?

It depends on what you trying to do, you can saves as external files, or as ProjExtState, or hardcoding things right in the script.
Really depends on what you are trying to do, and what variables.

I would prefer to store data directly to project file, but I don't know an easy way to store table data.
I know it's possible to store tables to external files, but I wish there was a "better" way :

Here's an example - each button is a Lua table (and should be stored when the script is closed):

In my opinion a "better" way is one that doesn't execute the data as code (loadstring/loadfile). It really depends on the contents of the table and structure of the data though.

I used this for serializing a flat table (without nesting): https://github.com/ReaTeam/ReaScript...s.lua#L118-146.

One thing to keep in mind is project extstates are limited of 2^12-(key length)-2 bytes (less if the key contains spaces) after the project is loaded.

For the whole Exstate section, or for each sub categories/keys ?

If it is for keys, the string can be split under several ones.

Though, it makes thing more complex than it could be.

Maybe a dirty solution would be to use ProjectNotes.
I don't know if there is a limitation in size to this.

Ok so a workarround can be done ;P

@spk77
Note that your script seems pretty close to SpacemanTree Reazard of Oz :P

(But different though. You dont use Slots for eg)

Also, check lua native table.join and table.concat.

Thanks everyone! I think I'll just try different options.
