Hi,
I have a very large gziped text file (all ASCII characters and ~500GB)
that I want to stream and process line-by-line, and I thought the iopipe
library would be perfect for this, but I can't seem to get it to work.
So far, this is the closest I have to getting it to work:
import iopipe.textpipe;
import iopipe.zip;
import iopipe.bufpipe;
import iopipe.stream;
void main()
{
auto fileToRead = openDev("file.gz").bufd.unzip(CompressionFormat.gzip);
foreach (line; fileToRead.assumeText.byLineRange!false)
{
\\ do stuff
}
}
but this only processes the first ~200 odd lines (I guess the initial
read into the buffer). Can anyone help me out?
Do you have a sample file I can play with? Your iopipe chain looks
correct, so I'm not sure why it wouldn't work.
