_Reading Files_
It is recommended to create a global context with a special method that handles
file reading from Python. The `read_file` helper in the following snippet will
read bytes from `sheetjs.xlsx` and generate a Base64 string:
The file data can be read in Python and encoded as Base64. The `set_object_item`
method on the internal context can assign to properties of the global object.
`mini-racer` does not expose a dedicated API to reference the global object.
The standard approach is to evaluate `this` in the JavaScript engine:
```py
from base64 import b64encode;
from STPyV8 import JSContext, JSClass;
from py_mini_racer import MiniRacer;
# Create context with methods for file i/o
class Base64Context(JSClass):
def read_file(self, path):
with open(path, "rb") as f:
data = f.read();
return b64encode(data).decode("ascii");
globals = Base64Context();
with open("sheetjs.xlsx", "rb") as f:
file_data = b64encode(f.read()).decode("ascii");
# The JSContext starts and cleans up the V8 engine
with JSContext(globals) as ctxt:
print(ctxt.eval("read_file('sheetjs.xlsx')")); # read base64 data and print
# Create context and obtain a handle to `this`
ctx = MiniRacer();
global_scope = ctx.eval("this");
# assign to the `fileData` global property and parse
ctx._ctx.set_object_item(global_scope, "fileData", file_data);
