The Not opcode should use the ! operator, meanwhile it uses the - operator

Add This ASAP!

Or tell a method how to recompile after edit ...

There's No Option To Re Assemble & Recompiler
Fix This

Tried hbctool to reassemble

Error:
assert os.path.exists(f"{path}/metadata.json"), f"metadata.json not found."
AssertionError: metadata.json not found

I've run ~/hermes-dec/parsers/hbc_file_parser.py file.js.hbc and it seems, it always returns the following error

  File "~/hermes-dec/parsers/hbc_file_parser.py", line 807, in <module>
    hbc_reader.read_whole_file(file_descriptor)
  File "~/hermes-dec/parsers/hbc_file_parser.py", line 763, in read_whole_file
    self.read_header_from_buffer() # Defines self.header
  File "~/hermes-dec/parsers/hbc_file_parser.py", line 488, in read_header_from_buffer
    assert sha1(file_data[:-SHA1_NUM_BYTES]).digest() == file_data[-SHA1_NUM_BYTES:]
AssertionError

• find confirms it is Hermes JavaScript bytecode, version 90.
• I'm on Python 3.10.5.

Hello developers,

I would like to know if you have any option to return the code to index.android.boundle after changes in the hasm file ?

When u add Reassembler option? Or Tell A Method How To Reassemble? 🥲
This disassembler function better than HBC TOOL.

Hello,

I wanted to reach out and make you aware of a typo I noticed in the file README.md:

The folder which holds the decompilation tools is currently "decompilation", not "decompiler". As such, the command could be updated as follows:

~/hermes-dec/decompilation/hbc_decompiler.py assets/index.android.bundle /tmp/my_output_file.js

A very small issue overall, but I figured it may be worth bringing up.

Thank you, and I appreciate the hard work spent developing this tool!

The full error message is UnicodeEncodeError: 'charmap' codec can't encode character '\u2502' in position 68: character maps to <undefined> which happens while printing instructions. As from the readme, you tested on the same version and it seems you have it worked. Any suggestions?
