ECMAScript binary decompiler¶

Frontier Smart products with the Venice 8 module store a different directory archive. Most of the files stored there are written in the ECMAScript language and converted to binary files. They are most likely used to create the web interface for the devices.

esbin.ES_BIN_SUFFIX = '\\.es\\d?\\.bin'¶

This module will accept files with an extension that matches the defined regular expression. The following examples illustrate which file names are included:

>>> esbin.is_valid_ext('foobar.es.bin')
True
>>> esbin.is_valid_ext('foobar.es')
False
>>> esbin.is_valid_ext('foobar.es6.bin')
True

esbin.ES_BIN_MAGIC = b'\x07\x00\xad\xde'¶

ECMAScript binary files always start with header information and a file signature, which is DE AD 00 07 (ScriptMonkey v1.8).

fsapi.ecmascript.esbin.is_valid_ext(name: str) → bool¶

Applies the ES_BIN_SUFFIX pattern on the given string.

Parameters:: name – usually the file name to test/ validate
Return type:: bool:
Returns:: True if “.es[:number:]?.bin” was found in the given string; False otherwise.

class fsapi.ecmascript.esbin.Decompiler(decompiler_path: str, file_path: str)¶

Wrapper for executable decompilers.

property code: str¶

Returns the decompiled source code as UTF-8 string.

Returns:: the decompiled source code
Return type:: str

do_final() → str¶

Executes the decompiler binary

Raises:: ValueError – if the input file is invalid
Returns:: the decompiled source code
Return type:: str
