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 formatâ one hexcode per line, followed by its character. See ./text_tables/* for examples.
By default, eksd uses a built-in fancy text-tableâ 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....
00018e90: 5454 5454 5466 8260 6488 7660 5454 5454 .....DRACULA....
00018ea0: 5464 6e82 7084 867c 7e6e 6882 5462 6868 .CHRISTOPHER.BEE
00018eb0: 5454 5454 5454 6668 6086 6e54 5454 5454 ......DEATH.....
00018ec0: 5454 5462 6876 7c54 7688 6c7c 8470 5454 ...BELO.LUGOSI..
And here's that same file in Vimâs xxd (just because I feel like showing off):
$ xxd castlevania.nes | grep -A4 "18e80"
00018e80: 5454 5454 866e 6854 6460 8486 5454 5454 TTTT.nhTd`..TTTT

Installation
Making a binary requires an implementation of Common Lisp installed:
Steel Bank Common Lisp is our implementation-of-choice. Itâs available on
most operating systems under the package name sbcl
.
You also need the library-manager Quicklisp, which can be installed quite easily, including via our Makefile.
To install Quicklisp, build a binary, and install it, simply:
$ make quicklisp
$ make build
$ sudo cp eksd /usr/local/bin/eksd
Bam, you've made and installed a binary! Cool!
Tests
eksdâs tests can be run from a REPL using ASDF:TEST-SYSTEM
, or from the
Makefile target âtestâ.
* (asdf:test-system :eksd)
* (asdf:test-system :eksd/unix)
`$ make test
