Added `bin/bin/tar-entry.sh` to build a compressed tarball for an entry. The compressed tarball is formed by gnu tar with options so that the same entry file content will always produce the same compressed tarball, byte for byte. As some files are missing from some entries, one should use the `-W` option as in: ```sh bin/tar-entry.sh -v 5 -W 2020/ferguson1 ``` Added `make form_entry_tarball` to the top level `Makefile` to build entry tarballs even when files are still missing. Added `make verify_entry_files` to verify that all entries have all of their files listed in their manifest, plus the top level ioccc.css and var.mk files. As file entry files are still missing (due to HTML files that need to be built), the overall `make quick_www` and `make www` do **NOT** (yet) exit when the `make verify_entry_files` fails. Improved `bin/chk-entry.sh` by removing some variables that were not needed. TODO: Improve `bin/` tool exit codes as the current use is a bit silly. TODO: Clean out some variables used in `bin/` tools as some of then are only set printed in debug statements. TODO: Clean up usage messages, some of the options listed to not match the `getopts(1)` parsing. In some cases the option needs to be parsed but needs to be ignored by the tool because another tool automatically passes along certain options that really have no effect. Such ignored options need to be show as "This option is ignored" in the usage message.
To build:
make
There is an alt version which is the originally submitted entry. See Alternate code below for details.
To use:
./prog <a number of arguments>
Try:
./try.sh
Alternate code:
An alternate version of this entry, prog.alt.c, is provided. This alternate code does not contain improvements suggested by Gil Dogon; it is the author's original entry.
Alternate build:
make alt
Alternate use:
Use prog.alt as you would prog above.
Judges' remarks:
For this one liner it is best to avoid prime numbers. The output groups factors in the x-y dimensions. How many factors can be represented before you run out of command line argument space? How could you modify the program to experiment with numbers that have more or larger factors?
Author's remarks:
Visual factorization 1-liner. Try:
gcc -o prog prog.c
./prog @
./prog @ @
./prog @ @ @
./prog @ @ @ @
./prog @ @ @ @ @ @
./prog @ @ @ @ @ @ @ @
./prog @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @
Inspired by Animated Factorization Diagrams.
prog.alt.c is the original version that I submitted. Gil Dogon kindly improved it during the review. Thank you!
