Hey gang,
I'm not seeing an obvious 'doh!' type solution. Here is my question:
Let's say I have a bunch of data output files and I want to merge the last
line from each into another table. For simplicity sake, let's say that the
table looks like this:
1 2 3
4 5 6
7 8 9
and I've read that into a string called str.
How do I get the 7 8 9 gracefully? I could read it into a table and just
grab the last line, but I would prefer to do it in one fell swoop, as I'm
dealing with data files that have many lines to each run.
I've tried the following:
_,_,last = string.find(str,'([^\n]*)')
which produces the expected result
1 2 3
I try anchoring it with the following
_,_,last = string.find(str,'(^\n]*$)')
which produces
nil
Am I misunderstanding how the '$' anchor works? It seems like it should be
brain-dead easy to do this (proving that I am past brain-dead at the
moment).
Thanks for any insight!
yrs,
Keith
