This includes some notices to those who wish for a greater challenge. In the 1998/schweikh3 the man page (and its copy to demonstrate the entry) have been updated slightly but only in comment (move 'or' from the command suggested to render it in text to its own line before the next command also in comment). The bugs file was updated for an entry or two.

## To build:
|
|
|
|
``` <!---sh-->
|
|
make all
|
|
```
|
|
|
|
There is an alternate version available. See [Alternate code](#alternate-code)
|
|
below for more details.
|
|
|
|
|
|
## To use:
|
|
|
|
``` <!---sh-->
|
|
./dlowe < file > pootfile
|
|
|
|
./dlowe < file
|
|
```
|

### Bugs and (Mis)features:
|
|
|
|
The current status of this entry is:
|
|
|
|
> **STATUS: missing or dead link or links - please provide it or them**
|
|
|
|
For more detailed information see [1998/dlowe in bugs.html](../../bugs.html#1998_dlowe).
|
|
|
|
|
|
## Try:
|
|
|
|
``` <!---sh-->
|
|
./dlowe < README.md
|
|
./dlowe < README.md > README.poot.md
|
|
```
|
|
|
|
Why is there different output?
|
|
|
|
Also try:
|
|
|
|
``` <!---sh-->
|
|
./try.sh
|
|
```
|
|
|
|
Did you spot the Easter egg there?
|
|
|
|
|
|
## Alternate code:
|
|
|
|
The original entry was just a text based pootifier. This alternate version is
|
|
that program.
|
|
|
|
|
|
### Alternate build:
|
|
|
|
``` <!---sh-->
|
|
make alt
|
|
```
|
|
|
|
|
|
### Alternate use:
|
|
|
|
```
|
|
./dlowe.alt < file > pootfile
|
|
```
|
|
|
|
What's the difference between this and `dlowe`?
|
|
|
|
|
|
### Alternate try:
|
|
|
|
``` <!---sh-->
|
|
./try.alt.sh
|
|
```
|
|
|
|
Did you spot the Easter egg there?

## Judges' remarks:
|
|
|
|
Why could this this entry be considered a utility? Well because it
|
|
is able to convert content-free web pages into useful web pages.
|
|
|
|
To see why, try using an online version, modified for use as
|
|
a CGI program: <https://web.archive.org/web/20001025182142/http://pootpoot.com/poot/pootify?URL=http://www.microsoft.com>
|
|
|
|
We are sure that you will find that new web page to make a much
|
|
more consistent level of quality. :-)
|
|
|
|
|
|
### Historical remarks:
|
|
|
|
A CGI script such as:
|
|
|
|
``` <!---sh-->
|
|
#!/bin/sh
|
|
# pootify - a sample CGI pootifier
|
|
#
|
|
POOT="/usr/local/bin/dlowe"
|
|
LYNX="/usr/local/bin/lynx"
|
|
ECHO="/usr/bin/echo"
|
|
EXPR="/usr/bin/expr"
|
|
${ECHO} "Content-type: text/html"
|
|
${ECHO}
|
|
if [ -z "${QUERY_STRING}" ]; then
|
|
${ECHO} "QUERY_STRING not found"
|
|
else
|
|
URL=`${EXPR} "$QUERY_STRING" : '[Uu][Rr][Ll]=\(.*\)'`
|
|
if [ -z "${URL}" ]; then
|
|
${ECHO} "No URL given in QUERY_STRING"
|
|
elif [ X`${EXPR} "${URL}" : '[Ff][Ii][Ll][Ee]:'` != X0 ]; then
|
|
${ECHO} "file: based URLs are not allowed"
|
|
else
|
|
${LYNX} -restrictions=all -source "${URL}" | ${POOT}
|
|
fi
|
|
fi
|
|
```
|
|
|
|
can be used to pootify web pages. This has been added as
|
|
[pootify.cgi.sh](%%REPO_URL%%/1998/dlowe/pootify.cgi.sh) which forbids `file://` based URLs and which
|
|
uses `lynx(1)` with the option referred to above. This will not, of course,
|
|
render it as html but rather show the modified html. Nevertheless, this has
|
|
**NOT** been tested as a CGI script with a webserver to display a pootified web
|
|
page.
|
|
|
|
The [pootify.sh](%%REPO_URL%%/1998/dlowe/pootify.sh) script has also been added which is a modification
|
|
to the above script which can be used to render html files locally with the
|
|
added bonus that one can use `file://` URLs. If one wants a CGI script they
|
|
should use the above one instead. You can use the script
|
|
[pootify.sh](%%REPO_URL%%/1998/dlowe/pootify.sh), however, to download and generate html files that you
|
|
can look at locally in a browser or pipe through `less(1)`. For instance:
|
|
|
|
``` <!---sh-->
|
|
./pootify.sh URL=https://microsoft.com | less
|
|
|
|
./pootify.sh -r URL=https://microsoft.com > ms.html
|
|
```
|
|
|
|
where the first one would show the text as rendered but without links, images
|
|
etc. and the second one would write the html to `ms.html` so that you could open
|
|
it in a browser.
|
|
|
|
For an old example of it working as a CGI script see
|
|
<https://web.archive.org/web/20040326083431/http://www.pootpoot.com/poot/pootify/?URL=http%3A%2F%2Fwww.ioccc.org>.

## Author's remarks:
|
|
|
|
This program is a text filter, it reads `stdin` and outputs the
|
|
"corrected" text to `stdout`.
|
|
|
|
It is obfuscated in that the code is painful to look at and
|
|
its purpose and mode of operation are not terribly obvious.
|
|
More importantly, it is a tool for further obfuscation, in that it
|
|
can take any text and render it unintelligible.
|
|
|
|
Suggested uses: add to your `MANROFFSEQ` environment variable for man page
|
|
enjoyment; use it to turn the GPL into the `PPL`; see what happens when you
|
|
run `perl4` programs after they've been run through it; "encrypt" sensitive
|
|
(but unnecessary) documents...
