Where is VrFileSink in gr-atsc?

GNU Radio

README.singla_flow in gr-atsc directory shows a great framework for ATSC
Tx & Rx.
However, it mentioned VrFileSink & VrFileSource, on which I have no
idea. I searched the whole package directory without finding their
codes.
Is there anything wrong with my configuration or the atsc module is not
completely implemented?
Thanks

Vr* are remnants of pspectra code on which the initial versions of
gnuradio and the initial ATSC implementations were based on.

The gnuradio equiv of VrFileSource/Sink is gr.file_source and
gr.file_sink. See
gnuradio-core/src/lib/io/gr_file_{source,sink}.{cc,h,i}

Yes, the atsc 2.x module is not completely implemented.

I played around with it earlier this year, and some of the modules
work in the gnuradio 2.x framework, but the rest still only work
in gnuradio 0.9, waiting to be ported to 2.x. Those that need
to be updated are:

GrAtscBitTimingLoop3
GrAtscFieldSyncChecker
GrAtscEqualizer
GrAtscFieldSyncDemux

Everything else can be done in 2.x using a USRP: file sink,source,
pll,root-raised-cosine,viterbi,reed-solomon,de-interleaver,
de-randomizer,etc. A ‘hybrid’ of 2.x and 0.9 actually works, but
I had to use an old version of RedHat 9 linux just to get gnuradio 0.9
to compile, for the 4 modules listed above. Attempts at porting those
are in gr-atsc, and they compile and run but don’t work correctly.

The ATSC code has not been completely ported to the 2.x and 3.x code
base. That particular document is referring to the 0.9 series. Most
of the stuff maps one-to-one onto the new code.

I will put some effort into the ATSC port to get it “unstuck” in the
near future.
