REPORT_CONTEXT_ATTR_NAME not available in streamlit 1.8.1

[CKoes]

Hy,

in streamlit 1.8.1 report_thread is not available any more.
Is there a workaround?

Thx

Hi @CKoes

I will try to resolve it in the next days.

Thanks for the update.

A workaround that has worked for me is to replace REPORT_CONTEXT_ATTR_NAME with SCRIPT_RUN_CONTEXT_ATTR_NAME

from streamlit.scriptrunner.script_run_context import SCRIPT_RUN_CONTEXT_ATTR_NAME

@contextmanager
def st_redirect(src, dst):
    placeholder = st.empty()
    output_func = getattr(placeholder, dst)

    with StringIO() as buffer:
        old_write = src.write

        def new_write(b):
            if getattr(current_thread(), SCRIPT_RUN_CONTEXT_ATTR_NAME, None):
                buffer.write(b + '')
                output_func(buffer.getvalue() + '')
            else:
                old_write(b)

        try:
            src.write = new_write
            yield
        finally:
            src.write = old_write

That solution worked for me in 1.10.0! Thank you!

In streamlit==1.13.0 I had to import SCRIPT_RUN_CONTEXT_ATTR_NAME like this:

from streamlit.runtime.scriptrunner.script_run_context import SCRIPT_RUN_CONTEXT_ATTR_NAME
