YAOS (Yet Another OS/2 Shell) version 0.9, Copyright 1994
This is a shell that runs on top of cmd.exe. Its features are:
* Unix-like file name completion using the <esc> or <tab> key
* a history of previously used commands with ability
to access them using commands like: !!, !4, !v test.c
(those familiar with unix would know what I am saying).
Of course, the up & down cursor keys will scroll through
previous commands too.
* ability to change directory to any [drive:\directory]
in a single command using the normal 'cd' command.
* full support for prompt setting in OS/2
* full implementation of command line editing
* a popup window that displays the possible file names for
completion. You can scroll through the entries in this
popup window using the up and down arrow-keys, Home, End,
PageUp and PageDown keys. You can also search for a particular
file name by typing its name directly onto the popup window.
['-w' option when starting YAOS]
* Alt-H keystroke will bring up a popup window containing
commands that are stored in history. Again, you can scroll
through this list using the cursor keys, Home, End, PageUp &
PageDown keys. (The window will only appear if there are two or
more commands in history).
* [-f] argument: Fast mode. Directory changing program like
vcd does not work in this mode. However, choosing this mode
results in better YAOS performance in terms of speed.
(The functionality of programs like vcd is planned to be included
in future releases of YAOS).
* [-i] argument: Defaulting to insert mode on startup.
* directory name that is completed using <esc> or <tab> will
have the back slash appended to the end of the name.
* Implementation of aliases. You define aliases in YAOS, save them
into a file and later retrieve them. You can also specify an alias
file when starting YAOS with the option [-a <filename>]. You have
to specify the full path name for the <filename> unless it is
located in the current directory. A total of up to 9 argument
replacements (from %1 to %9) is allowed in aliases. You can also
chain aliases. (But you should avoid cycles in the chain). To read
or write an alias file inside YAOS, refer to online help on alias:
(Type: '? alias' without the quotes at prompt.)
You can also unset an alias by using the unalias <keyword> command.
* In the file name completion popup window, the maximum string that
is common to all possible names is matched. (Previously, matching
is done from what the user keys in before bringing up the popup
* Emacs like editing keys are implemented.
Ctl-v : PageDown
Alt-v : PageUp
Ctl-p : Previous Line
Ctl-n : Next Line
Ctl-a : Beginning of line
Ctl-e : End of Line
Ctl-f : Forward a character
Ctl-b : Back a character
Alt-f : Forward a word
Alt-b : Back a word
New in this release
* Instead of keying in the startup options from the command line, you
can define an environment setting in the config,sys file to hold
the options. For example, you can do the following:
set YAOS=-w -f -m -a -i c:\yaos\alias.fil
However, you can overwrite the 'set' options from the command line.
* In the filename completion popup window, after typing in one or more
characters, hitting the <Tab> key will cause YAOS to match again as
much as possible the likely completing file name.
* Thanks to a sugguestion by David Begley from Australia, I have managed
to reduce the size of the file YAOS.EXE considerably. Compare it
with the YAOS.EXE file prior to v0.9. Also, note that YAOS now uses
both EMX.DLL and EMXLIBC.DLL. This will benefit those who run many
applications compiled using emx/gcc.
* Use of '&' character to 'detach' tasks. [User suggestion]
* Use of ';' separator for multiple commands [User suggestion]
* Customize color settings for popup windows [User suggestion]
* A quick directory changer like vcd or ncd
* Any reasonable feature requests from YOU!
This release is by no means a bug free version. However, I hope you'll
use and like YAOS. Suggestions and comments (including bug reports) are
1) Copy YAOS.EXE to a PATHed directory (eg. C:\OS)
2) Copy EMX.DLL & EMXLIBC.DLL to a LIBRARY directory (eg. C:\OS\DLL)
(Note: The EMX.DLL & EMXLIBC.DLL files included with YAOS must be used.
You may not use any earlier versions of the DLL files. If earlier
versions of the DLL files exist, you have to delete them. If not,
YAOS may not function properly.)
3) Now you can safely run YAOS
NOTE: Failure to perform the above steps will result in improper execution
