-v must interpret escape sequences

Hi, @benhoyt.
-v must interpret escape sequences. I hate this spec of awk, but anyway, reality is what it is.
$ goawk -v VAR='\t' 'BEGIN{printf VAR}' | hexdump -C
00000000 5c 74 |\t|
$ mawk -v VAR='\t' 'BEGIN{printf VAR}' | hexdump -C
00000000 09 |.|
$ gawk -v VAR='\t' 'BEGIN{printf VAR}' | hexdump -C
00000000 09 |.|
Hi @ko1nksm, thanks for your recent bug reports. This is an interesting one. I'll take a look at these in the next few days.
Out of interest, what are you using GoAWK for? Are you using it as a Go library or via the goawk command line tool?
I am testing if goawk (command line tool) can be used as an implementation of awk that shdotenv uses internally.
If you are interested, you can perform the test by following the steps below.
$ printf "FOO='ABC'" | SHDOTENV_AWK=goawk ./src/shdotenv --no-allexport -e -
FOO='ABC'
# Note: incorrect output
$ printf "FOO='ABC'" | SHDOTENV_AWK=goawk ./src/shdotenv -f jsonl -e -
{ "FOO": "\bABC\b" }
# or run all tests
$ shellspec -e AWK=goawk
