cxmon is available under the terms of the GNU General Public License. See the
file "COPYING" that is included in the distribution for details.


Overview
--------

cxmon is an interactive command-driven file manipulation tool that is
inspired by the "Amiga Monitor" by Timo Rossi. It has commands and features
similar to a machine code monitor/debugger, but it lacks any functions for
running/tracing code. There are, however, built-in PowerPC, 680x0, 80x86,
x86-64, 6502 and Z80 disassemblers and special support for disassembling
MacOS code. By default, cxmon operates on a fixed-size (but adjustable)
memory buffer with adresses starting at 0.


Installation
------------

Please consult the file "INSTALL" for installation instructions.


Usage
-----

cxmon can be started from the Shell or from the Tracker (BeOS), but command
line history doesn't work when started from the Tracker.

Options:
  -m  enables symbolic MacOS A-Trap and low memory globals display in the
      680x0 disassembler
  -r  makes cxmon operate in real (virtual) memory space instead of an
      allocated buffer

If no additional command line arguments are given, cxmon enters interactive
mode. Otherwise, all remaining arguments are interpreted and executed as cxmon
commands.

The default buffer size is 1MB.

The cxmon command prompt looks like this:

  [00000000]->

The number in brackets is the value of "." (the "current address", see the
section on expressions). You can get a short command overview by entering
"h".

Commands that create a longer output can be interrupted with Ctrl-C.

To quit cxmon, enter the command "x".


Constants, variables and expressions
------------------------------------

The default number base is hexadecimal. Decimal numbers must be prefixed with
"_". Hexadecimal numbers may also be prefixed with "$" for clarity. Numbers
can also be entered as ASCII characters enclosed in single quotes (e.g. 'BAPP'
is the same as $42415050). All numbers are 32-bit values (one word).

With the "set" command, variables can be defined that hold 32-bit integer
values. A variable is referred to by its name. Variable names may be arbitrary
combinations of digits and letters (they may also start with a digit) that
are not also valid hexadecimal numbers. Names are case-sensitive.

cxmon accepts expressions in all places where you have to specify a number.
The following operators are available and have the same meaning and
precedence as in the C programming language:

  ~   complement
  +   unary plus
  -   unary minus
  *   multiplication
  /   integer division
  %   modulo
  +   addition
  -   subtraction
  <<  shift left
  >>  shift right
  &   bitwise AND
  ^   bitwise exclusive OR
  |   bitwise inclusive OR

Parentheses may be used to change the evaluation order of sub-expressions.

There are two special symbols that can be used in expressions:

  .   represents the "current address" (the value of "." is also displayed in
      the command prompt). What exactly the current address is, depends on the
      command last executed. The display commands set "." to the address after
      the last address displayed, the "hunt" commands sets "." to the address
      of the first found occurence of the search string, etc.
  :   is used by the "apply" ("y") command and holds the value of the byte/
      half-word/word at the current address.

The "modify" (":"), "fill" ("f") and "hunt" ("h") commands require you to
specify a byte string. Byte strings consist of an arbitrary number of byte
values and ASCII strings separated by commas. Examples:

  "string"
  12,34,56,78,9a,bc,de,f0
  "this",0a,"is a string",0a,"with","newlines",_10


The buffer
----------

Those cxmon commands that operate on "memory" operate on a buffer allocated
by cxmon whose size is adjustable with the "@" command. The default buffer
size is 1MB. The buffer is an array of bytes where each byte has a 32-bit
integer address. Addresses start at 0 and are taken modulo the buffer size
(i.e. for the default 1MB buffer, addresses 0 and 100000 refer to the same
byte).

The buffer is the working area of cxmon where you load files into, manipulate
them, and write files back from. Arbitraty portions of the buffer may be used
as scratch space.


Commands
--------

The following commands are available in cxmon ('[]' marks a parameter than
can be left out):


  x                        Quit cxmon

quits cxmon and returns to the shell.


  h                        Show help text

  ??                       Show list of commands

displays a short list of available commands.


  ver                      Show version

shows the version number of cxmon.


  ? expression             Calculate expression

displays the value of the given expression in hex, decimal, and ASCII
characters. If the value is negative, it is displayed as a signed and unsigned
number.


  @ [size]                 Reallocate buffer

changes the size of the buffer to the given number of bytes while preserving
the contents of the buffer. If the "size" argument is omitted, the current
buffer size is displayed.


  i [start [end]]          ASCII memory dump

displays the buffer contents from address "start" to address "end" as ASCII
characters. Entering "i" without arguments is equivalent to "i .". The value
of "." is set to the address after the last address displayed.


  b [start [end]]          Binary memory dump

displays the buffer contents from address "start" to address "end" in a binary
format. Entering "b" without arguments is equivalent to "b .". The value of
"." is set to the address after the last address displayed.


  m [start [end]]          Hex/ASCII memory dump

displays the buffer contents from address "start" to address "end" as hex
words and ASCII characters. Entering "m" without arguments is equivalent to
"m .". The value of "." is set to the address after the last address displayed.


  d [start [end]]          Disassemble PowerPC code

disassembles the buffer contents from address "start" to address "end".
Entering "d" without arguments is equivalent to "d .". The value of "." is
set to the address after the last address displayed.


  d65 [start [end]]        Disassemble 6502 code

disassembles the buffer contents from address "start" to address "end".
Entering "d65" without arguments is equivalent to "d65 .". The value of
"." is set to the address after the last address displayed.


  d68 [start [end]]        Disassemble 680x0 code

disassembles the buffer contents from address "start" to address "end".
Entering "d68" without arguments is equivalent to "d68 .". The value of
"." is set to the address after the last address displayed.


  d80 [start [end]]        Disassemble Z80 code

disassembles the buffer contents from address "start" to address "end".
Entering "d80" without arguments is equivalent to "d80 .". The value of
"." is set to the address after the last address displayed.


  d86 [start [end]]        Disassemble 80x86 (32-bit) code

disassembles the buffer contents from address "start" to address "end".
Entering "d86" without arguments is equivalent to "d86 .". The value of
"." is set to the address after the last address displayed.


  d8086 [start [end]]      Disassemble 80x86 (16-bit) code

disassembles the buffer contents from address "start" to address "end".
Entering "d8086" without arguments is equivalent to "d8086 .". The value
of "." is set to the address after the last address displayed.


  d8664 [start [end]]      Disassemble x86-64 code

disassembles the buffer contents from address "start" to address "end".
Entering "d8086" without arguments is equivalent to "d8086 .". The value
of "." is set to the address after the last address displayed.


  : start string           Modify memory

puts the specified byte string at the address "start" into the buffer. The
value of "." is set to the address after the last address modified.


  f start end string       Fill memory

fill the buffer in the range from "start" to (and including) "end" with the
given byte string.


  y[b|h|w] start end expr  Apply expression to memory

works like the "fill" ("f") command, but it doesn't fill with a byte string
but with the value of an expression that is re-evaluated for each buffer
location to be filled. The command comes in three flavors: "y"/"yb" works on
bytes (8-bit), "yh" on half-words (16-bit) and "yw" on words (32-bit). The
value of "." is the current address to be modified,  the value of ":" holds
the contents of this address before modification.

Examples:
  yw 0 fff :<<8    shifts all words in the address range 0..fff to the left
                   by 8 bits (you can use this to convert bitmap data from
                   ARGB to RGBA format, for example)
  y 0 1234 ~:      inverts all bytes in the address range 0..1234
  yh 2 ff 20000/.  creates a table of the fractional parts of the reciprocals
                   of 1..7f


  t start end dest         Transfer memory

transfers the buffer contents from "start" to (and including) "end" to "dest".
Source and destination may overlap.


  c start end dest         Compare memory

compares the buffer contents in the range from "start" to (and including)
"end" with the contents at "dest". The addresses of all different bytes and
the total number of differences (decimal) are printed.


  h start end string       Search for byte string

searches for the given byte string in the buffer starting at "start" up to
(and including) "end". The addresses and the total number of occurrences are
displayed. The value of "." is set to the address of the first occurrence. 


  \ "command"              Execute shell command

executes the given shell command which must be enclosed in quotes.


  ls [args]                List directory contents

works as the shell command "ls".


  rm [args]                Remove file(s)

works as the shell command "rm".


  cp [args]                Copy file(s)

works as the shell command "cp".


  mv [args]                Move file(s)

works as the shell command "mv".


  cd directory             Change current directory

works as the shell command "cd". The name of the directory doesn't have to be
enclosed in quotes.


  o ["file"]               Redirect output

When a file name is specified, all following output is redirected to this
file. The file name must be enclosed in quotation marks even if it contains
no spaces. Entering "o" without parameters closes the file and directs the
output into the terminal window again.


  [ start "file"           Load data from file

loads the contents of the specified file into the buffer starting from address
"start". The file name must be enclosed in quotation marks even if it contains
no spaces. The value of "." is set to the address after the last address
affected by the load.


  ] start size "file"      Save data to file

writes "size" number of bytes of the buffer from "start" to the specified file.
The file name must be enclosed in quotation marks even if it contains no spaces.


  set [var[=value]]        Set/clear/show variables

If no arguments are given, all currently defined variables are displayed.
Otherwise, the value of "var" is set to the specified value. If "=value"
is omitted, the variable "var" is cleared.


  cv                       Clear all variables

clears all currently defined variables.


Examples
--------

Here are some simple examples for what is possible with cxmon.

Join "file1" and "file2" to "file3":

  [ 0 "file1"
  [ . "file2"
  ] 0 . "file3"

Remove the first 24 bytes (e.g. an unneeded header) of a file:

  [ 0 "file"
  ] 18 .-18 "file"

Load the cxmon executable and search for PowerPC "nop" commands:

  [ 0 "cxmon"
  h 0 . 60,00,00,00

Create a modified version of cxmon so that the prompt has " $" instead of
"->":

  [ 0 "cxmon"
  set size=.
  h 0 . "->"
  : . " $"
  ] 0 size "cxmon1"

Convert a binary file which contains 16-bit numbers in little-endian format
to big-endian format (or vice-versa):

  [ 0 "file"
  yh 0 .-1 :>>8|:<<8  
  ] 0 . "file"

Load a BeBox boot ROM image and start disassembling the system reset handler:

  [ 0 "bootnub.image"
  d 100


Using cxmon in your own programs
--------------------------------

cxmon provides a simple interface for integration in other programs. It can,
for example, be used as a monitor/debugger for an emulator (it is used in
Basilisk II in this way).

Here's how to do it (all functions are defined in the mon.h header file):

 1. Link all the cxmon object files, except main.o, to your program.
 2. In your program, call mon_init() before using any other cxmon functions.
 3. After calling mon_init(), set the mon_read_byte and mon_write_byte
    function pointers to the routines used for accessing memory.
 4. You can use mon_add_command() to add new commands to cxmon by specifying
    the command name, function and help text. From within your command
    function, you can use mon_get_token() and mon_expression() to parse the
    arguments and the mon_read/write_*() functions to access memory.
 5. To enter cxmon, call the mon() function like this:

      char *args[3] = {"mon", "-r", NULL};
      mon(2, args);

 6. If you're done with cxmon, call mon_exit().

66	Constants, variables and expressions
67	------------------------------------
68
69	The default number base is hexadecimal. Decimal numbers must be prefixed with
70	"_". Hexadecimal numbers may also be prefixed with "$" for clarity. Numbers
71	can also be entered as ASCII characters enclosed in single quotes (e.g. 'BAPP'

96
97	Parentheses may be used to change the evaluation order of sub-expressions.
98
99	There are two special symbols that can be used in expressions:
100
101	. represents the "current address" (the value of "." is also displayed in

107	half-word/word at the current address.
108
109	The "modify" (":"), "fill" ("f") and "hunt" ("h") commands require you to
110	specify a byte string. Byte strings consist of an arbitrary number of byte
111	values and ASCII strings separated by commas. Examples:
112
113	"string"
114	12,34,56,78,9a,bc,de,f0
115	"this",0a,"is a string",0a,"with","newlines",_10
116
117
118	The buffer
119	----------
120
121	Those cxmon commands that operate on "memory" operate on a buffer allocated
122	by cxmon whose size is adjustable with the "@" command. The default buffer
123	size is 1MB. The buffer is an array of bytes where each byte has a 32-bit
124	integer address. Addresses start at 0 and are taken modulo the buffer size
125	(i.e. for the default 1MB buffer, addresses 0 and 100000 refer to the same
126	byte).
127
128	The buffer is the working area of cxmon where you load files into, manipulate
129	them, and write files back from. Arbitraty portions of the buffer may be used
130	as scratch space.
131
132
133	Commands
134	--------

254
255
256	y[b\|h\|w] start end expr Apply expression to memory
257
258	works like the "fill" ("f") command, but it doesn't fill with a byte string
259	but with the value of an expression that is re-evaluated for each buffer
260	location to be filled. The command comes in three flavors: "y"/"yb" works on
261	bytes (8-bit), "yh" on half-words (16-bit) and "yw" on words (32-bit). The
262	value of "." is the current address to be modified, the value of ":" holds
263	the contents of this address before modification.
264
265	Examples:
266	yw 0 fff :<<8 shifts all words in the address range 0..fff to the left
267	by 8 bits (you can use this to convert bitmap data from

324
325	o ["file"] Redirect output
326
327	When a file name is specified, all following output is redirected to this
328	file. The file name must be enclosed in quotation marks even if it contains
329	no spaces. Entering "o" without parameters closes the file and directs the
330	output into the terminal window again.
331
332
333	[ start "file" Load data from file
334
335	loads the contents of the specified file into the buffer starting from address
336	"start". The file name must be enclosed in quotation marks even if it contains
337	no spaces. The value of "." is set to the address after the last address
338	affected by the load.
339
340
341	] start size "file" Save data to file
342
343	writes "size" number of bytes of the buffer from "start" to the specified file.
344	The file name must be enclosed in quotation marks even if it contains no spaces.
345
346

359	Examples
360	--------
361
362	Here are some simple examples for what is possible with cxmon.
363
364	Join "file1" and "file2" to "file3":
365
366	[ 0 "file1"
367	[ . "file2"
368	] 0 . "file3"
369
370	Remove the first 24 bytes (e.g. an unneeded header) of a file:
371
372	[ 0 "file"
373	] 18 .-18 "file"
374
375	Load the cxmon executable and search for PowerPC "nop" commands:
376
377	[ 0 "cxmon"
378	h 0 . 60,00,00,00
379
380	Create a modified version of cxmon so that the prompt has " $" instead of
381	"->":
382
383	[ 0 "cxmon"
384	set size=.
385	h 0 . "->"
386	: . " $"
387	] 0 size "cxmon1"
388
389	Convert a binary file which contains 16-bit numbers in little-endian format
390	to big-endian format (or vice-versa):
391
392	[ 0 "file"
393	yh 0 .-1 :>>8\|:<<8
394	] 0 . "file"
395
396	Load a BeBox boot ROM image and start disassembling the system reset handler:
397
398	[ 0 "bootnub.image"
399	d 100

402	Using cxmon in your own programs
403	--------------------------------
404
405	cxmon provides a simple interface for integration in other programs. It can,
406	for example, be used as a monitor/debugger for an emulator (it is used in
407	Basilisk II in this way).
408
409	Here's how to do it (all functions are defined in the mon.h header file):
410
411	1. Link all the cxmon object files, except main.o, to your program.
412	2. In your program, call mon_init() before using any other cxmon functions.
413	3. After calling mon_init(), set the mon_read_byte and mon_write_byte
414	function pointers to the routines used for accessing memory.
415	4. You can use mon_add_command() to add new commands to cxmon by specifying
416	the command name, function and help text. From within your command
417	function, you can use mon_get_token() and mon_expression() to parse the
418	arguments and the mon_read/write_*() functions to access memory.
419	5. To enter cxmon, call the mon() function like this:
420
421	char *args[3] = {"mon", "-r", NULL};
422	mon(2, args);
423
424	6. If you're done with cxmon, call mon_exit().
