I need to replace one line in a ton of . json files

Ithorian [comrade/them, he/him]@hexbear.net to Linux@lemmy.ml – 33 points –

I'm updating foundry to a version 11 and it broke an ass ton of my assets cause they're all "verified version 10"

So all I have to do is change that number, they're just maps so no need to update anything else, but I have like 400+ files to convert all in individual folders.

Please tell me there's an easy way to do this. (I'm on Linux obviously)

I have made a python script and ran it on a clone of your git repo to confirm it works, simply run it at the root directory of wherever the files are, it will walk through and find module.json and do the replace.

#!/usr/bin/env python3

import re
import os

import fileinput

pattern = re.compile(r'(?P\.+)\"compatibility\":{\"minimum\":\"(?P\\d+)\",\"verified\":\"(?P\\d+)\"},(?P\.+)')

def make11(match):
    if match.groupdict().get('min', None) and match.groupdict().get('ver', None):
        return f"{match.groupdict()['pre']}\"compatibility\":{{\"minimum\":\"11\",\"verified\":\"11\"}},{match.groupdict()['post']}"

for root, dirs, files in os.walk("."):
    for file in files:
        if file == "module.json":
            for line in fileinput.input(f"{root}/{file}", inplace=True):
                print(re.sub(pattern, make11, line))

edit: lemmy is fucking with the formatting and removing the fucking regex group names, which will bork it. I've tried fixing it, dm me if you want me to send a downloadable link to the script

If using Python, why not just use JSON module? Simpler and easier maintain without all those regex.

Still +1, on sed if one is on Linux.

Neat script; just a touch overkill IMO compared to just using sed and bash!

Changing the minimum may be undesirable - I think it's only the latter value that needs to go from 10 -> 11.
