Awk-Batteries VS awk-vm

It's nice that everyone is supporting this, I've written a portable awk module that takes control of the parsing and it is SLOW (and a little buggy). I'm a little bummed that nobody will use it but this is truly a step in the right direction.

I guess for the people that are still using nawk, you can set up an AWK envvar so you can { awk -f $AWKU/ucsv.awk -f <(echo '{print NR, $1}') }

if you have gawkextlib, you can -i csv, you can also download this and put it in your $AWKPATH then you just -i ucsv and use the csv file as normal. if you need an array with headers let me know.

I wrote a parser that does what -F, does but correctly, you can see that its actually very difficult. Not only that, but there are extensions to csv, some csv have a header which means that instead of $1 $2 $3 ..., you just name the field instead, which means you have to ignore the first record. there's also other things, but csv is a difficult format to parse.

Awk is awesome! Glad that they are looking to modernize the book. It wasn't really necessary, all the code examples in the original edition of the book still run just fine, although some are somewhat dated, like printing ASCII bar graphs. They also had examples of writing VMs, parsers and interpreters in the book, which run on modern implementations.[0]
