ELC Disassembler
elcd is a small disassembler for Emacs Lisp byte-compiled files.
Usage
Pass the byte-compiled file as an argument
$ ./elcd my-byte-compiled-file.elc
elcd can also read from its standard input:
$ echo '(nothing)' | ./elcd
Building
List of compilation dependencies:
- gcc
- bison
- flex
- perl
- wget
To build elcd, just run make
.
Implementation notes
A part of elcd is generated from Emacs's source code. A small perl
script parses src/bytecode.c
and compiles useful information to an
opcode table in opcode.c
. See mk_opcode.pl
.
elcd implements a reader for a large subset of Emacs Lisp. See lex.l
and
parse.y
for the lexer and grammar definitions.
