CMD - Command Line Interpreter for Menuet
Copyleft Chemist - dmitry_gt@tut.by
Version 0.27
As my english is not well, I will tell a few words about this
program. It supports 14 commands, such as cp (copy file),
rn (rename file), ps (process list), kill (kill process) etc.
You can type 'help' after starting this shell to examine with
other commands. Also it uses several special symbols, such as
&, /, . and +. Use & sumbol to enter params. For example,
type tinypad&cmd.asm to open cmd.asm file in tinypad editor.
/ symbol is used to run special command scripts for CMD.
It's syntax is: /filename without extension (For example,
type /autoexec to execute autoexec.cmd file for CMD). And +
symbol is used in cp and rn commands. You must type
cp example.asm+example.bak to copy example.asm file to
example.bak. Use dot to launch program, if CMD command and
other external command match. For example, type help for
'help' command or type .help to run 'help' program.
This shell supports executeing special command
scripts (something like .BAT files in MS-DOS). This files
have an .CMD extinsion and u must use / symbol to execute it.
U can use any CMD commands and filenames in this scripts.
But you can't run other scripts from any CMD script (/ symbol).
I recommed to use tipypad editor to edit this scripts and do
not leave spaces and other symbols after commands in the script
file, because it's executeing is not very developed yet.
And it's strongly recommended to use ends command in the end
of the script, because there are some problems with redrawing
the window after executing scripts without this command.
Every time when you launch CMD autoexec.cmd file automatically
executes. You can edit or delete this file if you want.
This version of CMD shell supports IPC. It mean, than you can
write your own programs for this shell. Look at .ASM files in
the Examples directory in this archive. I think that you will
understand them without any difficulties. Do not forget, that
you need CMDIPC.ASM file to compile this sources. It's
recommended to compile it with MACROS.INC file (included in
this archieve) to make their size smaller.
And now about some bugs etc.
----------------------------
I've noticed, that there are some difficulties with files with
1 or 2 symbols in extension. I recommend do not use such files
not only in CMD, but almost in every programs in MeOS. It's
possible to create such file in tinypad, and then (in MS-DOS or
Windows) Scandisk will find errors in filenames etc. CMD do
not support properly such filenames now.
In CMDIPC.INC and CMD.ASM I used 5-th function (pause), because
I need it when CMD communicates with IPC programs. It's
even possible, that it will not enough 1/100 sec. on slow PC's,
because CMD need this time to finish IPC-command from other
IPC-program. U can change ebx value in CMDIPC.ASM in pause1:
if you want. But it slows communication betwen CMD and
IPC-programs for CMD. I hope, that you understand my words. :)
Now (in this version) you can launch only one CMD shell.
Because it's difficult to make communication betwen several
copyes of CMD in memory and IPC-programs. I will solve this
problem in future.
I've tested this shell only on Ivan Poddubny's russian
distributive. Also I recommend you to use it. :) CMD shell
is included into this distributive (but possible not it's
final version).
Source code of this program is not optimized yet. I have such
manner of programming from my childhood that my source code
is not very "compact"
etc. ;-)
And now other information:
--------------------------
I do not want CMD design to change. I like white symbols on
the black background. If you want to change the source and
redistribute it, please, do not change it's design. :)
If you will find some bugs or you have some wishes (or even you
correct some mistakes in my english texts) -
email me: dmitry_gt@tut.by
And this program is distributed "as is". Use it on your own
risk. ;-)
And again - my English is not well. :)
That's all!
