Entry source is now prog.c for IOCCC years 2014 thru 2020, or is now dirname.c IOCCC years 1984 thru 2013. To achieve this state, we renamed the following: renamed: 2004/hibachi/src/hibachi.c -> 2004/hibachi/hibachi.c renamed: 2012/omoikane/nyaruko.alt.c -> 2012/omoikane/omoikane.alt.c renamed: 2012/omoikane/nyaruko.alt2.c -> 2012/omoikane/omoikane.alt2.c renamed: 2012/omoikane/nyaruko.c -> 2012/omoikane/omoikane.c renamed: 2012/omoikane/nyaruko.orig.c -> 2012/omoikane/omoikane.orig.c Modified `bin/subst.entry-index.sh` to add to entry `index.html` file, links to the `Makefile` and the _C code_ to the top navigation bar. Changed `bin/subst.entry-index.sh` VERSION from "1.2.2 2024-02-25" to "1.3 2024-03-02". Moved printing the Inventory link in the top navigation bar from `bin/subst.entry-navbar.awk` to `bin/subst.entry-index.sh`. Changed `bin/subst.entry-navbar.awk` VERSION from "1.0.1 2024-02-23" to "1.1 2024-03-02". Moved printing the Inventory link in the top navigation bar from `bin/subst.year-navbar.awk` to `bin/subst.year-index.sh`. Changed `bin/subst.year-index.sh` VERSION from "1.0 2024-02-11" to "1.1 2024-03-02". Changed `bin/subst.year-navbar.awk` VERSION from "1.0 2024-02-11" to "1.1 2024-03-02". Added location names (both default and common) to `author.html`. Changed `tmp/gen_author_json.sh` VERSION from "1.0 2023-06-06" to "1.1 2024-03-04". Added location names (both default and common) to `author.html`. Changed `bin/gen-authors.sh` VERSION from "1.2 2024-03-09" to "1.3 2024-03-04". The manifest and the resulting `.entry.json` files have been changed for `2004/hibachi` and `2012/omoikane`. The Makefiles for `2004/hibachi` and `2012/omoikane` copy the source file into the "previously used location". The `make clobber` rule removes the copied source. The `.gitignore` files have been updated accordingly. Improved how the concept of IOCCC terms _entry_, _author_ and _submission_ are used in markdown files. Links to markdown files (files ending in .md) within the repo were changed to link to HTML files (files ending in .html). Special cases where `README.md` became `index.html` were modified accordingly. Fixed URL for `bugs.html` in Makefile comments. Fixed name of `bin/sgi.sh` referenced in comments in `.gitignore` files. Links to locations within the repo are now relative. For example a link to `/contact.html` may become `../contact.html' or '../../contact.html` depending on the directory level of the markdown file. Nearly all links with absolute URLs under _https://www.ioccc.org_ or `https://ioccc-src.github.io/temp-test-ioccc_ have been changed to relative paths within the repo. Some exceptions to this (such as referring to a GitHub repo) were preserved. Fixed a number of inside `faq.md` and `bugs.md`. Added HTML name tags (in the form of an _entry_id_) for each entry referenced in `bugs.md`. Fixed links from outside of `bugs.html` into `bugs.html` accordingly. Where FAQ entries are referenced, a named tag is used so that if a FAQ is ever renumbered, links outside of `faq.html` will still work. Changed the _inventory_order_ of a compressed tarball from _300_ to _100000_. While this may have been done for the manifest, this changed had not yet been propagated into the `.entry.json` files. Links to web sites that were in the for <URL> are now [URL](URL). Performed `name www` to process all of the above. Improved format of `authors.html`. Full names are now bold. Location codes are now links back into `location.html` and location names (both default and common) are now italics. Added _author_handle_ each author. Changed `bin/gen-authors.sh` VERSION from "1.1 2024-02-25" to "1.2 2024-03-09". Improved format of `location.html` as location codes are now bold, author counts in a given location are now bold, and location names (both default and common) are now italics. Changed `bin/gen-location.sh` VERSION from "1.0.1 2024-02-23" to "1.1 2024-03-04". Added italic location name after location code in entry `index.html` files. Changed `bin/output-index-author.sh` VERSION from "1.4.1 2024-02-23" to "1.5 2024-03-04". Added _Location of authors_ to the sidebar as a link to `location.html`. TODO: While nearly all of the above mentioned changes are likely correct, they likely introduced a few errors that need correcting.
4.5 KiB
Twenty Third International Obfuscated C Code Contest
Standard IOCCC stuff
View the index.html web page for the given winning entry for information on how
compile the entry 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 www.ioccc.org.
Use make to compile entries. It is possible that on non-Un*x / non-Linux systems the makefile needs to be changed. See the Makefile for details.
Look at the source and try to figure out what the programs do, and run them with various inputs. If you want to, look at the hints files for spoilers - this year we included most of the information included by the submitter.
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
We believe you will again be impressed with this year's winning entries.
This year, 2014:
We, the judges, were very surprised by this as many of the multiple authors submitted very different styles of entries.
This year was the second time the IOCCC size tool was used. Rule 2 required that when program source is fed as input to the current IOCCC size tool, and the IOCCC size tool -i command line option is used, the value printed should be less than or equal to 2053.
We were pleased to see that abuse of the rules was extended to abuse to the IOCCC size tool. Matt Zucker, followed by a few users, were able to discover cleaver use of certain // comments to perplex the size tool. The abuse was so bad that the judges released a critical and mandatory patch to the IOCCC size tool on 2014-09-23.
There were some great entries that did not win. Unfortunately some entries lost because they:
-
were too large according the IOCCC size tool and didn't even attempt to justify their excess by a clever abuse of the rules
-
depended on a single obfuscation trick
-
didn't work as documented
We hope the authors of some of those entries will fix and re-submit them for the next IOCCC.
There is a risk in submitting an entry that is similar to a well used theme by previous winning entries. Previous authors set a very high bar. A new winning entry must not only compete against submissions from the current year, they must also excel over any similar entries in some particularly impressive way.
On the delay in releasing the winning entries
We apologize on the delay of sending the authors the tarball for them to review. There were some unforeseen events, such as unplanned mandatory business travel, the death of a IOCCC judge mother, etc. that impacted our planned schedule for building the tarball of this year's winning entries.
During some of these forced delays, we took the time to better automate some of the tools needed to package the source for the winning entries to review and to post the edited entries to the web site. It is our intent that these changes made during those delays will make releasing future winning IOCCC entries a faster procedure.
p.s. The final advice given to Landon by his mom: "Have fun." We recommend following this advice were possible.
