YAOS, Yet Another OS/2 Shell

New in release (v1.9.2) ---------------------------- Fixed - Problem with spaces in actual command path Fixed - Problem with file name completion when previous command had a ~ Fixed - Problem with CTRL-<left> not backspacing on start of word Fixed - Tab completion lost end of text if done other than at end of line Updated - Internal help New - Code page switching support added - Thanks to Steven Levine for help. New - Some (experimental) wildcard support added. wildcard - shows the state (on | off ) wildcard on - turns it on wildcard off - turns it off NB The wildcard expansion is limited by the system's maximum command line length. So if you get an "out of memory" message then the best thing to do would be to use one program to find what you want and then pipe through xargs to the program you need that does not understand wildcards. ls -1 *.c | xargs -n 1 -i{} wc {} New in release (v1.9.1) ---------------------------- New $* for last argument of previous command eg: ls -lrt foo e $* Will edit foo New - Allow comments in sourced files Fixed - bug in escape from F1 filename completion introduced in 1.9.0 Fixed - bug in $* logic Changed - ~ extended to file/directory names eg cd ~foo -> cd %HOME%/foo New in release (v1.9.0) ---------------------------- Fixed - PATH handling - fixes crashes on "set path" Fixed - BEGINLIBPATH & ENDLIBPATH handling - Never worked Fixed - Search for executable without extension did not search cwd first Fixed - "SET" no longer displays NULL variables. Gave impression that "set foo=" did not delete Fixed - Blue help line length if other than 80 chars Fixed - Quoting on file completion - well it's better :-) Fixed - Title change - Thanks to Alex Taylor Fixed - Commands starting // \\ ./ .\ Changed - history comparison is now case sensitive New - Change previous command ^old^new New - Ctrl+L - Clears screen New - Exec/-x support in yaos.rc type files New - CD ~ to cd to environmental "HOME" New - -b switch to append invoked program object name to titlebar inside [] New in release (v1.8.1) ----------------------- 1) In filename completion, if "cd" or "chdir" is typed at the commandline, only directories (as opposed to all files) will become possible candidates. 2) If you typed something on the commandline before hitting Alt-H to display the history commands, YAOS will only show the possible matches. If none is found, then YAOS will show all as before. 3) Ctrl-D at the commandline exits YAOS if the commandline is empty. 4) A new icon for YAOS. New in release (v1.8.0) ----------------------- 1) Regarding 4) of v1.7, some users actually said they preferred the auto ycd feature of v1.6. I have therefore included a new option "-y" which, when specified, invoke ycd if a normal cd fails. 2) The title of the window running YAOS is changable now. In fact, it has been so all along provided that the YAOS icon is unnamed. Right mouse click on the YAOS icon and choose "Settings". Under the "General" tab, blank out the value of "Title". (Note: It must be completely blank out with no spaces even.) Now, double click on the YAOS icon, run a VIO program like TEDIT.EXE and see the window title change to TEDIT.EXE. You can also set the window title to any name you like using the new "title" command at the prompt. 3) Some users remarked that the YAOS icon is really one of the icons from Warp 4. In fact, it is not so if you are running OS/2 at 1024x768 or higher. At this resolution, you will see the 40x40 YAOS icon instead of the 32x32 Warp 4 icon. In this release, I have ensured that both icons are correct, although the 32x32 one is a bit messy. Is someone willing to design a nice YAOS icon for both 32x32 and 40x40 sizes? 4) PM programs started at the prompt will be brought to the foreground. Those started with "&" will be detached and (in most cases) be run at the background. 5) If only one directory name completion is possible, a second tab will perform a name completion inside the directory. Previously, you have to type something first before name completion will work. 6) If a directory has the same name as an executable, and if the name of the directory is typed at the command line, YAOS will change directory if the command ends with a back slash. Previously, the executable got called instead. 7) Starting from this release, if the OS/2 machine running YAOS has internet access AND if you DO NOT require a proxy to access the web, typing "ver" at the prompt will cause YAOS to check for the latest release version of YAOS. No longer do you have to check the ftp sites regularly to see if a new YAOS release is out. You just have to type "ver". New in release (v1.7) --------------------- 1) Typing "cd-" brings you back to the previous directory you were in. 2) Harddisk directory scanning by "ycd" is now stoppable using Ctrl-C or Ctrl-Break. 3) The "cd" command no longer invokes "ycd" when the directory specified is invalid. 4) Some users noticed that commands such as "dir" caused a partition wide scan before they were executed. This is partly due to YAOS trying to determine if the command is an executable program, and, if it is, whether it is a PM executable, so that the executable can be started on a separate session. This resulted in unacceptable slowdown for users with large partitions (or simple long PATHed environment variable). To bypass the executable determination, prepend the command with a back slash "\" and YAOS will execute it right away. For example, the "dir" command would become "\dir" instead. (Note: There should be no space between the slash and the command.) 5) A YAOS Icon created by one of you! Thanks! 6) Fixes for a few bugs which caused core dumps. New in release (v1.6) --------------------- 1) Typing "\" or "/" at the command line brings you to the root directory of the current drive. 2) YAOS now checks if the executable to be launched is a PM app. If it is, the PM app will be started on a separated session. As a result, your YAOS window will not be minimized. (Thanks to a few of you who have written to me with the instructions for doing this.) 3) Using Ctrl-Right-Cursor (Alt-F) or Ctrl-Left-Cursor (Alt-B) while performing command line editing brings the cursor to a position following a non alphanumeric character. Previously, the cursor positions itself following a space. 4) The -x startup option of YAOS is fixed to allow YAOS specific commands to be executable also. 5) A new startup option, -c, is added to YAOS to allow YAOS specific commands to be executed, after which, the YAOS session will terminate. 6) You can now forced a directory rescan of any drive using the "ycd" command by providing as parameter the drive letter followed by a colon. For example, to force a rescan of the C drive, use the following command: ycd c: A user has pointed that since directories are created and removed quite frequently, it might be useful to perform a rescan of the drives every time one starts up OS/2. You can do that now by having the following line in your CONFIG.SYS file. (The actual drive letters and directory may vary.) CALL=c:\yaos\yaos.exe -c "ycd c:" -c "ycd d:" The above line performs a rescan of drives C and D whenever OS/2 starts up. New in release (v1.51) ---------------------- 1) Fix for core dump when completing a filename that begins with the slash. New in release (v1.5) --------------------- 1) Implementation of default application launching for different file extensions. Using the "ext" command, you can specify what application you want launched when a file of a particular extension is executed. For example, after setting "ext txt=tedit", whenever you type a filename with an extension txt at the command line, the program "tedit" will be called up automatically to edit that file. To start all exe programs on separate sessions, you can set "ext exe=start". However, YAOS does not currently check if an exe program is PM or not. If you know of an easy way to do this, please enlighten me. Thanks. 2) Quick directory changing works on drives that you do have write access on. With such drives, a file YCD_DATX (where X is the drive alphabet) will be created in the root directory of drive C so as to prevent a rescan of the drive every time "ycd" is used on it. 3) File name completion for cases like c:<TAB> works now. 4) A bug fix for usage of %environment-variables% in "set" statements. New in release (v1.01) ---------------------- 1) By popular demand, when cycling through previous commands using the up/down arrow keys, the cursor is now positioned at the end of the command line instead of at the beginning. 2) Alias for "exit" works now. 3) When a change directory is performed and if there is no immediate match, YAOS automatically invokes the quick directory changer. New in release (v1.00) ---------------------- 1) A vcd-like quick directory changer. The new command "ycd <directory>" performs a quick change to the directory specified anywhere on the same drive. When the command is first issued on any drive, a directory scan is carried out and the results stored in a file named "YCD_DAT" in the root directory of that drive. Subsequently, YCD_DAT will be used whenever a ycd is called. If you make changes to the directory structure, you can cause yaos to rescan by deleting the YCD_DAT file. Currently, ycd do not support cross directory searches. [Note: If you are on a networked drive and do not have write permissions, using ycd will result in a directory scan every time. (I have not personally tested ycd on a networked drive.)] 2) Implemented CMD.EXE's F1 functionality. To search through previously used commands, just type in the first few characters and hit the F1 function-key to cycle through matches. You can also use the Up/Down arrow keys to do the same thing. As a result, command editing after a search no longer begins at the end of the commandline. 3) A command selected in a history popup window (using <Alt-h>) is not executed immediately. This allows you to edit the command before issuing it. 4) Wrap-around now occurs in all popup windows. New in release (v0.99) ---------------------- 1) Bug fixes: "!.." works if ".." is in cmdline history. (plus a few minor fixes) 2) 'x' no longer exits yaos. Both 'exit' and Alt-x do. 3) Environment variable expansion works now. For example, you can do something like this: set path=%path%c:\mydir; 4) No longer exits unnecessarily when Ctrl-C is pressed while executing a command. In fact, yaos mask out SIGINT and SIGBREAK signals. 5) Use of '&' to detach a process like in Unix. 6) New command "kill <pid>" that destroys the process whose id is <pid> (<pid> can be specified in hexadecimal (e.g., 0x261) or decimal (e.g., 609). Make use of the OS/2 program "pstat /c" to find out the pids of active processes. New in release v0.98a --------------------- This release fixes a bug in v0.98 relating to writing aliases to files. It has no additional feature over v0.98. New in release v0.98 -------------------- 1) The '-r <filename>' option is obsolete. In its place, a new option '-s <filename>' is added. The file may contain both alias definitions and environment variables settings. 2) The command "alias -r <filename>" is now replaced by a more general command called "source <filename>". The contents of <filename> may contain both alias definitions and environment variables settings. 3) Alias expansions will not be shown if the '-q' flag is used. 4) Alias definition in a file requires the "alias" keyword. Previously, an alias definition in a file looked like: c=cls Now, it must be specified as: alias c=cls OR alias c cls 5) Verify on/off settings work now. 6) Hitting the <Esc> key clears the command line.
