[Jprogramming] Scanning a large file

[Yoel Jacobsen]

Even for regex, I don't see how to avoid manually reading the file in chunks
which is too imperative style for me. Again, consider the Python example:

for line in file.readlines():
  match_object = re.search("(<= csn )\w+", line)
  if match_object:
    process(match_object.group(0))

The regex can be precompiled as well.

This works on a 5GB file as well as on small files since readlines() take
care for reading the file in chunks.

Is there a way to do it a consice way in J?
