awkでテトリス

awkネタ
以前どっかのサイトに載せられていたawkで作ったテトリス。
これでテトリスが出来るのだからすげー。
ぜひ遊んでみてください。

# awktris - tetris in 19 lines of code, or 1516 bytes.
# hand-crafted self-extracting AWK.

# (c) 2004 Tobias Nygren <tnn+awktris-awk@nygren.pp.se>
# Do whatever you like as long as I'm credited properly.

# Compatibility
# -------------
# mawk, popular on Linux systems, doesn't work because of aggressive input
# buffering. AWK was never intended for interactive use and awktris relies
# on a hack assuming the AWK implementation leaves terminal buffering alone.
# Use GNU awk instead.

# /usr/bin/awk on Solaris is horribly broken for other reasons. They however
# ship an /usr/bin/nawk which works fine. BSD awks and Tru64 work fine.
