make all
./rcm < file.gz
where file.gz
is some gzipped file.
For more information try:
./try.sh
For a good no-op try:
gzip -c < rcm.c | ./rcm
NOTE: this is done in the try.sh script as well, along with some other commands including a way to do the above command but with more steps.
Except for some silly requirements regarding input validation, CRC checking, and
similar unimportant fluff, this program is a fully compliant
RFC1951/RFC1952
(GNU Gzip) file uncompressor. Feed it a
gzip
compressed file on standard input, and it will write the fully
uncompressed original file to standard output.
“The 184 characters worth of defines in the build file have been
carefully offset by 184 redundant and unnecessary ‘{
’, ‘}
’, and ‘;
’
characters in the source file.”
“Using only 216 characters out of a maximum of 256, the build file meets and actually exceeds specification.”
“The program source is less than 3,100 characters in length and uncompresses the file emacs-19.34b.tar.gz in about 130 seconds on my HP 9000/735. The now obsolete source file `inflate.c’ from the GNU gzip source tree is 31,613 characters in length and uncompresses the emacs distribution file in slightly under 25 seconds. Thus:
3100 / 130 = 23.85 -vs- 31613 / 25 = 1264.52
which represents a better than 530% improvement in the ratio of source file size to execution time.”
“The inflate algorithm requires that over 400 characters worth of constants and tables be defined. Which means the program itself had to be squeezed down to about 1,100 IOCCC countable bytes.”
