The initial release of `bin/readme2index.sh` tool that converts `READMD.md` and various JSON files such as `.winner.json` as well as "author/author_handle.json" files. Applied the `readme2index.sh` tool to generate `2020/ferguson1/index.html`. We generated the `2020/ferguson1/index.html` by executing: ```sh ./bin/readme2index.sh -v 3 2020/ferguson1 ``` NOTE: This above tool requires **pandoc to be installed**. See the [pandoc web site](https://pandoc.org) for how to install. We used _HomeBrew_ to install it, but there is also a _macports_ process as well. NOTE: While the above web page does have formatting issues, it is a first attempt data driven programmatic web page generation. Some adjustments can be made by mostly improving `ioccc.css`, and some perhaps by modifying how `bin/pandoc_wrapper.sh` invokes pandoc. But probably most of the improvements can be made by fixing and improving `ioccc.css`. TODO: Fix and improve the `2020/ferguson1/index.html` web page by fixing and improving `ioccc.css`. Moved scripts and tools needed to generate HTML pages into a new `/bin` subdirectory. TODO: Consider getting rid of the [build-ioccc repo](https://github.com/ioccc-src/build-ioccc) and just use the `/bin` subdirectory. NOTE: Some links in the `2020/ferguson1/index.html` web page do not (yet) exist. TODO: Once the basic format of the `2020/ferguson1/index.html` web page is somewhat reasonable, generate `index.html` pages for other winners. Generate the year level `index.html' files. Generate the top level HTML files, including the missing `location.html` file. Greatly simplified the `.winner.json` file format, removing a number of fields that were not strictly needed for generating an inventory on a `index.html` page. Updated various versions: * `bin/gen-author.sh` VERSION="1.3 2024-01-14" * `bin/gen-inventory.sh` VERSION="1.0 2024-01-14" * `bin/manifest.winner.json.awk` VERSION="1.0 2024-01-14" * `bin/pandoc_wrapper.sh` VERSION="1.3 2024-01-14" * `bin/readme2index.sh` VERSION="1.0 2024-01-14" * `bin/subst.default.sh` VERSION="1.1 2024-01-14" * `bin/subst.winner-index.sh` VERSION="1.1 2024-01-14" * `tmp/gen_path_list.found.sh` VERSION="1.1 2024-01-14" * `tmp/gen_winner_json.sh` VERSION="1.1 2024-01-14" The `.winner.json` file format from winner_JSON_format_version "0.5 2023-11-04" to "1.0 2024-01-14". All `.winner.json` files have been updated to use the new `.winner.json` file format. The manifest (`tmp/manifest.numbers` and `tmp/manifest.csv`) has updated to use the new `.winner.json` file format. The following procedure was used to generate the `tmp/manifest.csv` manifest file: 0. open [manifest.numbers](manifest.numbers) in numbers: modify if/as needed NOTE: Please try to keep the [manifest.numbers](manifest.numbers) spreadsheet in order order. Use Organize -> Sort -> ((Sort Now)) to sort. NOTE: Empty fields in the [manifest.numbers](manifest.numbers) spreadsheet are not allowed. By default, a cell that is empty is colored as a warning. 1. File -> Export To -> CSV... * 1a. `[ ]` Include table names (unset) * 1b. Text Encoding: Unicode (UTF-8) * 1c. Click ((Save..)) 2. Save As: manifest.csv * 2a. Select the `tmp` directory 3. Click ((Export)) * 3a. If needed click ((Replace)) 4. Execute ./tmp/[fix_csv.sh](fix_csv.sh) NOTE: You must run the [fix_csv.sh](fix_csv.sh) in the above step in order to make the CSV file usable by other tools. NOTE: If no changes are needed in the above step, the original file content will be restored. 5. Execute ./tmp/[gen_path_list.found.sh](gen_path_list.found.sh) NOTE: The above step silently performs a `make clobber` at the top level, and so it takes a bit of time. NOTE: If no changes are needed in the above step, the original file content will be restored. 6. Execute ./tmp/[check_path_list.sh](check_path_list.sh) NOTE: The above step prints nothing and for an exit 0, then all is well. If there is a problem, such as files found that are not part of the manifest, or files in the manifest that are not found, then an error message will be printed and the tool will exit non-zero. If errors are reported, go back to step 0 and correct the errors. 7. Execute ./tmp/[run_all.sh](run_all.sh) ./gen_winner_json.sh NOTE: The above step will take a few seconds to run. It will rebuild all `.winner.json` files for all winners. NOTE: If no changes are needed in the above step, the original file content will be restored. 8. Execute `git status` and inspect changes NOTE: Check in changes if and as needed. NOTE: In a number of shell scripts under `bin/*.sh`, and in the `bin/manifest.winner.json.awk` script you will find comments of the form: ``` ``` This is a note that when tools such as `jnamval` (and `jval` and `jfmt`) are ready, these gross hacks should be replaced with calls to those tools. Until they are ready, some must be careful with the layout of JSON files. A number of bugs and typos have been fixed. NOTE: Fixing typos in the files touched by this comment is welcome. This includes scripts, data files, text files, etc. The _inventory_order_, _display_as_, _display_via_github_. and _winners_text_ fields of the [manifest.numbers](manifest.numbers) spreadsheet were just set to have some initial values. As they impact the inventory displayed on `index.html` pages, their content needs to be improved. NOTE: Improving the above mentioned fields of the [manifest.numbers](manifest.numbers) spreadsheet is welcome.
2011 marked the "The Twentieth International Obfuscated C Code Contest"
Standard IOCCC stuff
Look at the README.md file for the given winning entry for information on how to compile it and how to run the winning program. Look at the winning source and try to figure how it does what it does! You may then wish to look at the Author's remarks for even more details.
The IOCCC has a web site and now has a number of international mirrors. The primary site can be found at,
Use make to compile entries. It is possible that on non-Unix / non-Linux
systems the Makefile needs to be changed. See the Makefile for details.
This year we included most of the information included by the submitters in the README.md files.
Read over the Makefile for compile/build issues. Your system may require certain changes (add or remove a library, add or remove a #define).
Some ANSI C compilers are not quite as good as they should be. If yours is lacking, you may need to compile using gcc instead of your local compiler.
Remarks on some of the entries
There were some outstanding entries that did not win. Unfortunately some very good entries lost because they:
-
did not follow the "one program - one file" rule;
-
depended too much on 32 bit architectures;
-
were more of the "obfuscated math" kind rather than the "obfuscated C" kind.
We hope the authors of some of those entries will fix and re-submit them for the next IOCCC.
We believe you will be impressed with this year's winners. The Best of Show is a fine example of character stitching. But don't ignore the other winners! There are games, puzzle solvers, utilities, eye candy, calculators and graphical and audio tools.
This year all winners are different, and there is a winner from a new country - China! Many winners won for the first time. (Please note that judging is done completely anonymously. Be warned that we may disqualify entries that reveal the identity of the submitter).
Final Comments
IMPORTANT NOTE: See contact.html for up to date contact details as well as details on how to provide fixes to any of the entries. See also the IOCCC FAQ for addition information on the IOCCC.
