Add preview of 1984-2019
The 2020 winners are hinted it, but the source code is not there,
nor are the hints. Someone could look into the HTML and
see what was commented out, but that is not a problem because
WHO won is known and the name of their AWARD is known already.
Moreover a number of the winners have talked about what their
entirs do, so the commented out spoiler text is not a bit problem.
One will find HTML commented out with:
<!-- XXX remove when 2020 is ready
2020 links here
XXX remove when 2020 is ready -->
The "XXX remove when 2020 is ready" string is found at the
start and end comment blocks. Again, soneone could read
what was commented out, but that is OK since most of that
information is known or can be known. The following files
have such HTML comment blocks in them.
./winners.html
./years-spoiler.html
./years.html
In addition, ./all/summary.txt was modified to not
include the 2020 entries for the momemt.
The 2020 winner code AND write-ups are NOT part of this set.
p.s. The all/all.tar.bz2 does not contain the 2020 source code (yet?).

On Writing An IOCCC One-Liner
|
||||
|
||||
There is a tug-of-war when writing a one-liner between obscurity
|
||||
and length. On the one hand, one-liners are often obscure in nature,
|
||||
simply by doing so much with so little. As well, the reduction of
|
||||
interesting logic into a single line typically involves transformations
|
||||
that tend to obscure the logic in the hunt for fewer bytes.
|
||||
|
||||
Sometimes, the minimalist logic can be easily deciphered because
|
||||
of the simplified logic required to get it into one line, and due
|
||||
to the almost necessary reliance on stdlib routines to do the heavy
|
||||
lifting. printf, scanf, getchar, putchar, atoi, isspace, isdigit,
|
||||
are succinct but explicit size-reducing functions, and may sometimes
|
||||
open an unwanted window on the nature of the otherwise obscured logic.
|
||||
|
||||
The flip-side, replacing these routines, invariably requires more
|
||||
bytes. So what is a one-liner-writer to do when confronted by such
|
||||
a choice? Therein lies the art form, and the risk: the additional
|
||||
obscurity requiring additional bytes may push a one-liner close to
|
||||
or over the limit. Fewer bytes is generally better, until it is not.
|
||||
|
||||
Further, the predilections of the judges may change daily, for all
|
||||
this author knows. The guidelines are opaque on purpose. So brevity,
|
||||
or better obscurity? Both if at all possible, but perhaps at some
|
||||
risk for being juuuuuust too long, or not quiiiiiiite obscure enough.
|
||||
|
||||
Finally, the desire for clean compilation is almost anathema to an
|
||||
obscure one-liner. The extra characters of the types and storage
|
||||
classes, which are historically implicit, but made explicit to
|
||||
silence modern compilers, tend to occupy the very precious bytes
|
||||
left in the one-liner budget.
|
||||
|
||||
It is a fun challenge to write something "interesting" within the
|
||||
draconian budget. As history has shown, most years someone conceives
|
||||
of something clever enough. This year, the present author is hopeful
|
||||
the artistic balance is deemed favorable, and is interesting to the
|
||||
world at large. But if not, it was still fun to write -- and with no
|
||||
small amount of angst for the final form of the entry, of which there
|
||||
were several different attempts at the same algorithm, each with
|
||||
different compromises in logic, expression, and obscurity mechanisms.
|
||||
|
||||
Because there is a tug-of-war between obscurity and brevity.
