update mc-apply.py

[ellensp]

Description

mc-apply.py no longer works with current CONFIG_EXPORT type 1

re wrote almost all of it from scratch so now it works.

Added help and documentation
extended to take a path to the input file on command line, but defaults to still looking for marlin_config.json in the current working directory

Requirements

use mc-apply.py

Benefits

• Produces requested files
• Updates Configuration.h and Configuration_adv.h
• A lot more readable
• Actually useful errors

I updated the config dump so it has file groupings as expected by mc-apply.py and then adjusted mc-apply.py to use our standard config.set(file, key, val) and config.add(file, key). I discovered that the ZIP format used for embedding is not compatible with macOS unzip so I switched to a more compatible algorithm. Compression is less efficient, but I also removed the ignore fields in the export, so the ZIP should not be too much larger.

I still cant this to work.

Very strange error. Looks like it did actually find and open the file so thats progress, but bombs out at the first KV pair entry.

Unless Im doing something wrong?

Seems like it goes to make a backup of the header file/s but the filename passed is a key so it looks for a file with the first key name and cant do it.

I dont actually see where it gets the Configuration.h or Configuration_adv.h names from, unless its assuming they are in the buildroot folder? But really it looks like its expecting them to be in the config json. My json extracted from the printer is flat.

Im so confused by how this is supposed to work.

@Ferrograph: You're using a version of Marlin from before this PR. Update to the latest bugfix-2.1.x.

I did update to the latest bugfix-2.1.x code base. Do I need to run "M503 C" on a printer that has the later firmware from Marlin firmware service? I thought only the mc-apply script had been updated?

The output you pasted says otherwise.

That is a third-party service and is unrelated to this project. Use Marlin from here (this repo) or download it from marlinfw.org.
