Files

from dexvstuff import Files

Files.create("example.txt")
Files.create(["dir1/file1.txt", "dir2/file2.txt"])

Files.write("example.txt", "Dexvstuff is cool")
print(Files.read("example.txt"))
Files.append("example.txt", "\nDexvstuff is even cooler")

print(Files.get_file_size("example.txt"))
Files.delete("example.txt")

JsdomRuntime

from dexvstuff import JsdomRuntime

runtime = JsdomRuntime()

print(runtime.eval("console.log('Dexvstuff is cool')"))
print(runtime.eval("new Promise((resolve) => setTimeout(() => resolve('Dexvstuff is cool'), 1000))", promise=True)) # resolves promises
print(runtime.eval('''(function() { return new Uint8Array([1, 2, 3]) })()''', byte_array=False)) # support js byte arrays

Wabt

from dexvstuff import Wabt

wabt = Wabt()


wat_output, errors = wabt.wasm2wat("example.wasm")
wasm_output, errors = wabt.wat2wasm("example.wat")
objdump_output, errors = wabt.wasm_objdump("example.wasm")

Files

• create(path): create file or directory
• read(path): read file content
• write(path, content): write content to file
• append(path, content): append content to file
• delete(path): delete file
• get_file_size(path): get file size in bytes
• exists(path): check if file/directory exists

JsdomRuntime

• eval(code, promise=False, byte_array=False): execute JavaScript code
  • promise: set to True if code returns a promise
  • byte_array: set to True if code returns a byte array

Wabt

• wat2wasm(file): convert .wat to .wasm
• wasm2wat(file): convert .wasm to .wat
• wasm_objdump(file): inspect WASM file
• wasm_decompile(file): decompile WASM to C-like code
• All WABT tools are supported but not all are defined in the wrapper, you can still use them through dynamic attribute access
  • Example: wabt.wasm_validate('file.wasm') will call the wasm-validate tool
  • See WABT documentation for all available tools
