# EKSD
|
||
|
|
|
||
|
|
xxd is a very good hexdump program that makes editing files on UNIX very easy.
|
||
|
|
It also doesn't support text-tables. Which sucks.
|
||
|
|
|
||
|
|
eksd is a clone of a good hexdump program (even matching several arguments
|
||
|
|
exactly)… except it supports text-tables.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
To see a hexdump of a file, just run:
|
||
|
|
```
|
||
|
|
$ eksd $FILE > $HEXDUMP_FILE
|
||
|
|
```
|
||
|
|
|
||
|
|
If you want to turn a hexdump (from eksd or xxd) back to a file:
|
||
|
|
```
|
||
|
|
$ eksd -r $HEXDUMP_FILE > $FILE
|
||
|
|
```
|
||
|
|
|
||
|
|
And to make a hexdump with a custom text-table:
|
||
|
|
```
|
||
|
|
$ eksd -t $TABLE_FILE $FILE > $HEXDUMP_FILE
|
||
|
|
```
|
||
|
|
|
||
|
|
Text-tables are in a simple format— one hexcode per line, followed by its
|
||
|
|
character. See ./text-tables/* for examples.
|
||
|
|
|
||
|
|
By default, eksd uses a built-in *fancy* text-table— it's basic ASCII,
|
||
|
|
except it'll print nice pictographics for newline characters, etc. These
|
||
|
|
require UTF, of course. If they don't work for you, use the "-a" arg to
|
||
|
|
revert to simple, non-fancy ASCII.
|
||
|
|
Note that specifying a text-table will override "-a", though.
|
||
|
|
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
Here's a part of Castlevania (EU) for the NES using its text-table:
|
||
|
|
```
|
||
|
|
$ eksd -t castle-table.txt castlevania.nes | grep -A4 "18e80"
|
||
|
|
00018e80: 5454 5454 866e 6854 6460 8486 5454 5454 ....THE.CAST....

|
||
|
|
```
|
||
|
|
And here's that same file in xxd (just because I feel like showing off):
|
||
|
|
```
|
||
|
|
$ xxd castlevania.nes | grep -A4 "18e80"
|
||

## Installation
|
||
|
|
Making a binary requires a Lisp (I recommend SBCL) and Quicklisp
|
||
|
|
(https://quicklisp.org).
|
||
|
|
|
||
|
|
Put this repository into your `quicklisp/local-projects/`, then run, in your
|
||
|
|
lisp interpreter:
|
||
|
|
```
|
||
|
|
# (ql:quickload '(eksd eksd-unix))
|
||
|
|
# (save-lisp-and-die "eksd" :toplevel #'eksd-unix:invoke :executable t)
|
||
|
|
```
|
||
|
|
|
||
|
|
And bam, you've made a binary. Cool.
