Given how problematic leading tabs in markdown files can be,
we have expanded all leading tabs in markdown files by:
```sh
find * -type f -name '*.md' -print |
while read -r file; do
rm -f "$file.tmp" ;
expand < "$file" > "$file.tmp" ;
mv -f -v "$file.tmp" "$file" ;
done
```
Given the previous changes to `bin/pandoc-wrapper.sh` and other recent
commits and recent pull requests, the were were **NO** changes to
any HTML files. This is a **good thing** as the expression goes.
No there are no leading tabs in any markdown files.
A check to catch any re-introduction of leading tabs
into any markdown file is on the way.
BTW: We do not have anything against leading tabs in files,
even though we have had to deal with their impact on forming
HTML from markdown files (as well as the calc source code).
It is just that this is one of those cases where tabs conflict
(sometimes caused by people wanting to change the classic
8-space tab model) with a desired outcome.
Perform `make www` to perform the above and test under macOS.

The Judges believe that this is the best one line entry ever received.

Compile on a UNIX system, or at least one using a C implementation that
|
|
fakes it. Very few people are able to determine what this program
|
|
does by visual inspection. I suggest that you stop reading this
|
|
section right now and see if you are one of the few people who can.
|
|
|
|
Several points are important to understand this program:
|
|
|
|
1. What is the symbol `unix` and what is its value in the program? Clearly
|
|
`unix` is not a function, and since `unix` is not declared to be a data type
|
|
(such as `int`, `char`, `struct foo`, `enum`, ...) what must `unix` be?
|
|
|
|
2. What is the value of the symbol `"have"`? (hint: the value is NOT 4
|
|
characters, or `'h'`, or a string) Consider the fact that:
|
|
|
|
``` <!---c-->
|
|
char *x;
|
|
```
|
|
|
|
defines a pointer to a `char` (i.e. an address), and that the `=` assigns
|
|
things of compatible types. Since:
|
|
|
|
``` <!---c-->
|
|
x = "have";
|
|
```
|
|
|
|
is legal C, what type of value is `"have"`?
|
|
|
|
3. Note that the following expressions yield the same value:
|
|
|
|
``` <!---c-->
|
|
x[3] *(x+3) *(3+x)
|
|
```
|
|
|
|
since addition is commutative. What can be said about this value?
|
|
|
|
``` <!---c-->
|
|
3[x]
|
|
```
