OnMyCommand is a UNIX shell script and AppleScript executor.
build your own Contextual Menu Item or GUI application.
For more information on building command descriptions see Command Description Manual.
Sources are included with Contextual Menu Workshop. Newest sources are
available on request.
Subscribe to OMC
mailing list to receive OMC-related announcements, seek support,
suggest features or discuss command descriptions.
OMC features in a nutshell:
- You can create a contextual menu item or an applet using UNIX shell script or
- You can specify for the 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. Context information is 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. Great thanks to Knut for devoting his time to this project. OMCEdit is a great companion to OnMyCommand. More info here.
User contributed command descriptions
Users are encouraged to submit command descriptions via OMCEdit so they
can be shared with other users here.
Classic contextual menu plug-ins are no longer supported in OSX 10.6 and higher. More information available
- Obtaining text context from front Cocoa application usually does not work. Only Shortcuts text context provides in specific apps can obtain text context via AppleScript.
- Finder item selection is unreliable starting with OSX 10.7. When you select item in one window, switch to another window and selecting a different item, Finder sometimes returns the first selection as the current one. A radar bug was opened with Apple long time ago and it does not seem to be high on their priority list.
- Starting with OSX 10.8 Apple removed support for ~/.MacOSX/environment.plist, leaving it only for Terminal.app. This means that if you have a script or tool, which relies on some environment viable set there it will work in Terminal.app but it will not work when executed via OMC. As a workaround you may use /OMC/Additional Tools/plist_env.sh in your command to set the env variables from ~/.MacOSX/environment.plist.
- Starting with Xcode 4 Apple removed support for editing nib files with Interface Builder 3 plug-ins. For more information refer to "Custom nib dialogs.rtfd" document.

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.
