Landon Curt Noll c6e6201209 release readme2index.sh version 1.0 2024-01-14
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.

2016 marked the "The Twenty Sixth 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 primary IOCCC web site can be found at,

https://www.ioccc.org/

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.

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 C compilers are not quite as good as they should be. If yours is lacking, you may need to compile using clang or gcc instead of your local compiler.

Remarks on some of the winners

This year's winners are impressive!

The "Most in need of debugging" (endoh) is very inventive in a way it produces its own text!

The "Most likely to be awarded" (ciura) has an amazing vocabulary!

There are again nods to winners of the years:

[1991/davidguy](http://ioccc.org/years.html#1991_davidguy)
[2011/blakely](http://ioccc.org/years.html#2011_blakely)

These nods to not run afoul of the guideline:

We tend to dislike programs that:
...
are rather similar to previous winners

because the entry (dogon) appropriately pays homage to past winners without blatantly reusing their code.

...We'll stop spouting spoilers now. Have fun exploring all the entries!

Remarks on some of submissions that did not win

Some entries tried to get around the size limit by submitting a data file that was really C code and then blindly including code in prog.c.

Quite a few entries suffered from undefined behavior like accessing uninitialized locals and/or reading-writing below the stack. We advise running your entry through valgrind to make sure those mistakes are avoided.

Using extra arguments to main, or arguments of wrong types as a quick and dirty way of declaring variables is now passé. Clang, for example, rejects them outright.

We hope the authors of some of those entries will fix and re-submit them for the next IOCCC.

Some entries seemed to have a good idea, but the implementation of the idea was limited in scope.

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.
