@OlehSuvorovSvitla
on windows, i cannt install leveldb , so i use wsl to run the python;
here is result from your file
https://1drv.ms/u/s!Aso5a3Kpi4YwgXekt87RSxpi-BTY?e=GTwciO

@iamqiz oh, thank you very much for this work!

I tested extracting the 000003 file for ~500kb for me and placing it in the extension's folder - and it also worked somehow o_O
So my tampermonkey after all the restarts start to see older scripts.
Now I enabled sync of files, hopefully, it will not happen again

I found myself unable to install the leveldb package via pip.

$ pip install leveldb
...
  × python setup.py egg_info did not run successfully.
  │ exit code: 1
  ╰─> [1 lines of output]
      Don't know how to compile leveldb for Windows!
      [end of output]
...

So I rewrite the script in go. Maybe someone finds it useful as well:

// Windows usesage: go run main.go "C:\Users\<USER>\AppData\Local\<VENDOR>\<BROWSER>\User Data\Default\Local Extension Settings\<EXTENSION_ID>"
//            i.e.: go run main.go "C:\Users\foo\AppData\Local\Google\Chrome\User Data\Default\Local Extension Settings\dhdgffkkebhmkfjojejmpbldmpobfkfo"
//     Linux usage: go run main.go "/home/<USER>/.config/<BROWSER>/Default/Local Extension Settings/<EXTENSION_ID>"
//            i.e.: go run main.go "/home/foo/.config/google-chrome-beta/Default/Local Extension Settings/gcalenpjmijncebpfijmoaglllgpjagf"

//            i.e.: go run main.go "/Users/foo/Library/Application Support/Google/Chrome/Default/Local Extension Settings/dhdgffkkebhmkfjojejmpbldmpobfkfo/"

package main

import (
	"bytes"
	"encoding/json"
	"fmt"
	"os"

	replace = regexp.MustCompile("[\\W\b]")
)

func must(err error) {
	if err != nil {
		panic(err)
	}
}

func main() {
	db, err := leveldb.OpenFile(os.Args[1], nil)
	must(err)
	defer db.Close()

	iter := db.NewIterator(nil, nil)
	defer iter.Release()
	for iter.Next() {

		if len(m) == 0 {
			continue
		}
		name := replace.ReplaceAll(bytes.TrimSpace(m[1]), []byte("_"))
		fullName := fmt.Sprint(string(name), ".user.js")
		fmt.Println("Writing to", fullName)

		content := struct{ Value string }{}

		must(os.WriteFile(fullName, []byte(content.Value), 0o644))

	must(iter.Error())

Hello, My windows 10 was crashed.

Which of these 2 files is the correct one to use to restore all the old scripts?
"..\Local\Google\Chrome\User Data\Profile 1\Local Extension Settings\dhdgffkkebhmkfjojejmpbldmpobfkfo\002379.log (There are many ldb data files in this directory)" and "..\Local\Google\Chrome\User Data\Profile 1\Sync Extension Settings\dhdgffkkebhmkfjojejmpbldmpobfkfo\000003.log"

I tried to run Python, leveldb failed.

Could someone please help me? Thank you very much.

you need the whole directory not just a single file.

@githubabcdefg as far as i know , window cannot run above script directly, but you can run it in window WSL,
additionly, above script use python2, if you use python3, try this py3 version:
https://gist.github.com/derjanb/9f6c10168e63c3dc3cf0?permalink_comment_id=3400197#gistcomment-3400197 (from Aceralon)

usage:
python extract_tampermonkey_script.py path/to/chrome/Local Extension Settings/dhdgffkkebhmkfjojejmpbldmpobfkfo
if you use WSL in window , the window path is maped to /mnt/ directory,
you can copy the "Local Extension Settings/dhdgffkkebhmkfjojejmpbldmpobfkfo" dir to D:\dhdgffkkebhmkfjojejmpbldmpobfkfo
and run py with: python extract_tampermonkey_script.py /mnt/d/dhdgffkkebhmkfjojejmpbldmpobfkfo
and the output JavaScript file will be placed where the script.py is

you need the whole directory not just a single file.

Thanks nice person.

Since I don't have WSL installed, I'll try it out in VMware, thank you very much for your help.
Thanks again.

I've tried different versions of Python, and it always seems to be a leveldb error.

you need the leveldb module. you can install it via pip.

$ python3 -m pip install leveldb

Hi there hope you are doing well

Need your urgent help. All my userscripts over the years i gathered are gone after the abrupt PC shutdown. Please help me to restore it

Chrome Version 103.0.5060.114 (Official Build) (64-bit)
TM version 4.18.0
Linux OS

If anyone can help me in the situation. It would mean a world to me, I am very devastated right now to what just happened suddenly out of nowhere

@rakitanc pack your extension directory ("/home/<USER>/.config/<BROWSER>/Default/Local Extension Settings/<EXTENSION_ID>" ) , and upload it to web cloud (google/Microsoft) ,share link to me, then i will restore it and send back to you

@iamqiz Thankyou so much brother. It's rare to find people like you nowadays who are helping this way. Because i was already sad and after not getting any help online I lost my hope actually But so happy to hear from you that finally someone came as a ray of hope

Sp just to update you with a good news..I got my scripts back by simply rebooting the PC. I just tried my luck when i didn't know what to do and Fortunately it worked.

But i would like to be in touch with you as i have one more technical issue that you might help with me. So if you don't mind can you share your Telegram, Discord or anything else so i could share it there

Looking forward to hearing from you

Thanks

@rakitanc happy to hear you got your script back

I'm not sure what this is supposed to do. I ran the code, got no errors, but I don't see the extracted scripts anywhere. Could someone post a screenshot of a successful extraction?

@EdFrees it will print "Writing to xxxx.js" and the "xxxx.js" are extracted scripts,they will be placed at python script directory

@EdFrees it will print "Writing to xxxx.js" and the "xxxx.js" are extracted scripts,they will be placed at python script directory

Okay. I'm not seeing it Writing anything. There are no js scripts in the folder where the python script is. All it gives is a blank line in the terminal and then I can type again. No errors. There are clearly old Tampermonkey scripts in the folder because when I open some of the files in a text editor I can see parts of the scripts I wrote.

Could the problem be that there are 2 ldb files containing different scripts?

@EdFrees i guess your tapermonkey dir is not valid leveldb database, the database dir include Manifest-* CURRENT *.ldb(or *.log) files and so on.
details about google leveldb:
https://github.com/google/leveldb/blob/main/doc/impl.md

@iamqiz I understand. I see the files that are mentioned in the post:
000010.ldb, 000012.ldb, 000013.log, CURRENT, LOCK, LOG, LOG.old, MANIFEST-000011
After I run the script some file names are changed. 000015.log and MANIFEST-000014. The LOG is also adjusted I think.

Could anyone please help me out trying to extract the scripts?

Nice! thanks a bunch

@iamqiz 佬，我把位于C:\Users\用户名\AppData\Local\Microsoft\Edge\User Data\Default\Extensions里的油猴插件拖出来后，油猴脚本消失了，这种情况可以恢复脚本吗？

@ziqian-L 油猴数据位于 "C:\Users<USERNAME>\AppData\Local\Microsoft\Edge\User Data\Default\Local Extension Settings\<EXTENSION_ID> 下, 如果有CURRENT *.ldb 等文件,那么可以恢复, 我的仓库可以在线恢复,不需要自己搭python环境 ,见: https://github.com/iamqiz/github-action-for-tapermonkey

谢谢大佬的解答，由于我在插件失效后将油猴重新安装了一遍，导致里面数据被覆盖了，已经找不回来了。
