### Overview
|
||||
|
||||
Misaka is a file concatenation utility, with at least two modes of
|
||||
operation:
|
||||
|
||||
gcc misaka.c -o horizontal_cat
|
||||
./horizontal_cat [files...] > [output]

cc misaka.c -o horizontal_cat

./horizontal_cat [files...] > [output]

||||
./vertical_cat [files...] > [output]

||||
./horizontal_cat misaka.c misaka.c > misaka2.c
|
||||
cc misaka2.c -o vertical_cat
|
||||
./vertical_cat [files...] > [output]
|
||||
```
|
||||
|
||||
Where [files...] are a list of text file names. Use "-" to read from stdin.

Horizontal cat
|

--------------
|
||||
One of my favorite unix utilities is *cat*. The best thing about it was
|
||||
that it was named "cat". That, and it's useful for quickly showing contents

of a file. Though it was primary meant for concatenating files, that

gcc misaka.c -o horizontal_cat

./horizontal_cat files...
|

```sh
|

cc misaka.c -o horizontal_cat
|

./horizontal_cat files...

```sh

```
|
||||
|
||||
### Vertical cat
|
||||
|
||||
Vertical cat
|
||||
------------
|
||||
Because *horizontal_cat* must know the maximum width of all files before
|
||||
writing any output, all files must be processed at least twice. To support
|
||||
stdin, file must be buffered to memory. This lead to the feature that

|
||||
mode with command line options would be no fun. Instead, vertical mode is
|
||||
enabled by concatenating the source code horizontally:
|
||||
|
||||
./horizontal_cat misaka.c misaka.c > misaka2.c
|
||||
gcc misaka2.c -o vertical_cat
|
||||
./vertical_cat files...
|

```sh

./horizontal_cat misaka.c misaka.c > misaka2.c
|
||||
gcc misaka2.c -o vertical_cat
|
||||
./vertical_cat files...
|
||||
```
|
||||
|
||||
*vertical_cat* works more or less like *cat*, except you can use
|
||||
*vertical_cat* to duplicate stdin:
|
||||
|
||||
./vertical_cat - -
|
||||
```sh
|
||||
./vertical_cat - -
|

```
|
||||
|

### Long cat
|
||||
|
||||
Long cat
|
||||
--------
|
||||
After *horizontal_cat* and *vertical_cat*, I thought, maybe all I really
|
||||
wanted was just more cats. So I implemented one more mode, this one is
|
||||
enabled by concatenating misaka.c vertically:
|
||||
|
||||
./vertical_cat misaka.c misaka.c > misaka3.c
|
||||
gcc misaka3.c -o long_cat
|
||||
./long_cat
|
||||
```sh
|
||||
./vertical_cat misaka.c misaka.c > misaka3.c
|
||||
gcc misaka3.c -o long_cat
|
||||
./long_cat
|
||||
```
|
||||
|
||||
*long_cat* outputs ASCII art of a cat to stdout. You can make this cat
|
||||
exponentially longer by concatenating more files vertically (up to 31 levels
|
||||
high, depending on sizeof(int) for your compiler):
|
||||
|
||||
./vertical_cat misaka.c misaka.c misaka.c > misaka4.c
|
||||
gcc misaka4.c -o loong_cat
|
||||
```sh
|
||||
./vertical_cat misaka.c misaka.c misaka.c > misaka4.c
|
||||
gcc misaka4.c -o loong_cat
|
||||
|
||||
./vertical_cat misaka.c misaka.c misaka.c misaka.c > misaka5.c
|
||||
gcc misaka5.c -o loooong_cat
|
||||
./vertical_cat misaka.c misaka.c misaka.c misaka.c > misaka5.c
|
||||
gcc misaka5.c -o loooong_cat
|
||||
|
||||
./vertical_cat misaka.c misaka.c misaka.c misaka.c misaka.c > misaka6.c
|
||||
gcc misaka6.c -o loooooooong_cat
|
||||
./vertical_cat misaka.c misaka.c misaka.c misaka.c misaka.c > misaka6.c
|
||||
gcc misaka6.c -o loooooooong_cat
|
||||
```
|
||||
|
||||
If your terminal has really thin fonts, you can also make this output fatter
|
||||
by concatenating files horizontally:
|
||||
|
||||
./vertical_cat misaka.c misaka.c | ./horizontal_cat - - > misaka7.c
|
||||
gcc misaka7.c -o long_fat_cat
|
||||
```sh
|
||||
./vertical_cat misaka.c misaka.c | ./horizontal_cat - - > misaka7.c
|
||||
gcc misaka7.c -o long_fat_cat
|
||||
|
||||
./vertical_cat misaka.c misaka.c | ./horizontal_cat - - - > misaka8.c
|
||||
gcc misaka8.c -o long_faat_cat
|
||||
./vertical_cat misaka.c misaka.c | ./horizontal_cat - - - > misaka8.c
|
||||
gcc misaka8.c -o long_faat_cat
|
||||
```
|
||||
|
||||
Output width is determined by the first level of stacked programs, so a
|
||||
triangle like the following will not have horizontally expanded output:
|
||||
|
||||
./horizontal_cat misaka.c misaka.c | ./vertical_cat misaka.c - > misaka9.c
|
||||
gcc misaka9.c -o same_as_long_cat
|
||||
```sh
|
||||
./horizontal_cat misaka.c misaka.c | ./vertical_cat misaka.c - > misaka9.c
|
||||
gcc misaka9.c -o same_as_long_cat
|
||||
```
|
||||
|
||||
Finally, if you lost track of how many misaka.c you have stacked together,
|
||||
you can feed the source to a brainfuck interpreter to get a overview of how
|
||||
the programs are stacked. Example:
|
||||
|
||||
perl bf.pl misaka9.c
|
||||
```sh
|
||||
perl bf.pl misaka9.c
|
||||
```
|
||||

||||
This outputs:
