can create standalone applets using the same command description format.
- Direct AppleScript support. You can put AppleScript code into
command description, no need to go through osascript call.
- Output window to see the result of command execution. In many
cases it eliminates the need to send the command to terminal.
- An option to paste clipboard content after command execution.
Most useful in text context with pbcopy or AppleScript's set
the clipboard to...
- Bug fixes. Most important fix involves a long standing bug with popen
execution mode aborting some commands. Now you should be able to
execute almost anything in popen mode.
- Knut Lorenzen's OMCEdit is now included with the main OnMyCommand
- Discussion forums. Some users expressed interest in having a
place to discuss command descriptions.
- BlackTree's QuickSilver now supports OMC commands as actions. You
can download the plug-in for QuickSilver here.
Give it a try!
- Worked around a problem with objects in Finder's column view in
Mac OS 10.3.
- Internal changes for Mac OS 10.3 Panther compatibility.
- Extensive reorganization of special words: dialog words now take
form of __DLG_XXX__. Old style names are still recognized for backward
compatibility but are not recommended.
- Three new Navigation Services dialogs have been added: choose
file, choose folder and choose object (file or folder)
- Two new execution modes have been added: silent execution using
system() call and terminal execution using iTerm.
- Added "Save As..." dialog. The path chosen with "Save As..." can
be passed to CLI as a command argument.
- New dialog type for input text is added: combo box. The dialog is
shown with edit field and popup choice. Handy for pre-defined items but
allows entering custom value.
- Fixed a problem with "text in clipboard" context when a selected
text was always preferred even if the context was explicitly "clipboard
- Changed the behavior of "Always" context. Now always means truly
always, no matter what is the context. Any application supporting
contextual menus will display the item. However, this exposes
contextual menu bugs in some applications (Camino, Safari, possibly
others). Please read the "Known Problems" section for details.
- Fixed a bug which caused strange problems in Carbon applications
(CodeWarrior or BBEdit Lite). The symptom was that all controls,
including scrollbars, were grayed out after contextual menu was invoked
on empty text selection. Thanks to Jayson Adams for providing a quick
solution. This bug was introduced in version 1.5.
- Fixed a bug which caused a crash in Internet Explorer. This bug
was introduced in version 1.5. Thanks to Ira Ruben for reporting this
problem. This is a recommended upgrade since this bug may show in other
programs as well.
- Text selection now works in Cocoa applications thanks to the code
submitted by Cocoa guru Jayson Adams of Circus Ponies Software.
OMC features in a nutshell:
- You can create a contextual menu item using UNIX CLI or
- You can control menu behavior via editable command description.
- You can control if a command is to be executed silently, in
terminal or with result in output window.
- You may add a path to the clicked file or folder as an argument
of your command.
- You may add a selected text or text from clipboard as an argument
of your command.
CommandDroplet is a small application executing commands in OMC format.
You may use the same command description for contextual menu and for a
standalone applet. CommandDroplet contains exactly one command
description in its resources. Objects in __OBJ_XXX__ family are
obtained from files dropped on CommandDroplet. Text selection objects
cannot be used with CommandDroplet (but clipboard content can be
accessed). More detailed information on droplets here.
A command description editor is available as a separate application.
It is called OMCEdit and is written by Knut Lorenzen (Knut.Lorenzen
Great thanks to Knut for devoting his time to this project.
OMCEdit is a great companion to OnMyCommand and you are encouraged to
download it and try. It is free too.
Please note that this application is not written nor supported by
Abracode, Inc. You can download OMCEdit here.

- Terminal in Mac OS X 10.4 prints some warnings about
.scriptSuite to Console when AppleEvent is used to launch it. It is not
the problem with OMC but with Terminal. It can be reproduced in Script
Editor by quitting Terminal and running the following simple script:
tell app "Terminal" to activate
This bug was fixed in Mac OS 10.4.7 but then
reappeared in 10.4.8 & 10.4.9
- If you choose "Always" for activation mode, the item will always
show in all applications supporting contextual menus. But it may also
show in unexpected places, especially in some menus in Cocoa
applications. It is a long standing problem in Cocoa framework which
does not really support contextual menu plug-ins.
- When you execute AppleScripts you must take care not to send
events to the application currently executing the contextual menu. For
example: if you control click in Finder and execute AppleScript which
sends events to Finder, you may end up locking Finder. This happens
when the script is executed in synchronous mode, blocking the host
application during execution. You should send the command to background
application (OMCDeputy) for execution or use osascript in popen
excution mode (OMC 1.8 or higher). When executing osascript in silent
system mode, you need to add ampersand at the end of your command
(background execution) and this will prevent hanging of the host
application. See command 223: "Set As Background" for sample usage
(workaround found by Fredrik Andersson).
