Documentation
The following document provides an overview of how to use CocoaDialog,
as well as the various run modes and commandline options available.
Visit the examples page to see more
practical examples of its use.
(It's really not as complicated as it may seem from this page).
This documentation is also available offline in the
Resources directory of the application bundle
(CocoaDialog.app/Contents/Resources/documentation.html).
Contents
Executing CocoaDialog
CocoaDialog is run directly from the commandline by executing the
binary file within the .app bundle.
The path to it will be
CocoaDialog.app/Contents/MacOS/CocoaDialog
If CocoaDialog is in your ~/Applications directory,
for example, the executable will be:
~/Applications/CocoaDialog.app/Contents/MacOS/CocoaDialog
See the examples page for a simple way
to find the binary in its most common locations.
From here on we will refer to this binary file as simply
CocoaDialog
CocoaDialog is always executed with the following format:
CocoaDialog runmode options
The runmode is always required, and specifies which GUI
control to use.
An example is:
CocoaDialog yesno-msgbox --title "Delete backups"
--text "Delete all the backups?" --informative-text "This cannot be
un-done"
See Run Modes / GUI Controls for a list of available controls.
Return Values / Output
The return value of a control will simply be printed to
stdout.
This makes it trivial to determine the user input in any
shell, programming or scripting language.
In bash you could find it like this:
rv=`CocoaDialog yesno-msgbox --string-output`
echo "User pressed the $rv button"
Controls that return multiple values will print each on its own
line (separated by newlines).
Global Options
The following options can be supplied for any of the run modes
(GUI controls).
| ‑‑title "text for title" |
Sets the window's title |
| ‑‑string‑output |
Makes yes/no/ok/cancel buttons return values as "Yes", "No",
"Ok", or "Cancel" instead of integers. When used with custom
button labels, makes it return the label you provided. |
| ‑‑no‑newline |
By default, return values will be printed with a trailing
newline. This will suppress that behavior. Note this will
only suppress the trailing newline on the last line
when a control returns multiple lines.
|
| ‑‑width integer |
Sets the width of the window. It's not advisable to use
this option without good reason, and some controls won't even
respond to it. The automatic size of most windows should suffice.
|
| ‑‑height integer |
Sets the height of the window. It's not advisable to use
this option without good reason, and some controls won't even
respond to it. The automatic size of most windows should suffice.
|
| ‑‑debug |
If you are not getting the results you expect, try turning on
this option. When there is an error, it will print
ERROR: followed by the error message.

Run Modes / GUI Controls
Notes: The right-most button of controls with buttons has
the key-equivalent of enter. Any button with a label "Cancel" has the
key-equivalent of escape.
msgbox
This control provides a generic message box. It allows you to
customize the labels of the buttons. At least one button
(--button1) must be specified. If labels for the
other buttons are not given, the buttons will not appear on the
message box.
Buttons go from right to left.
--button1 is the right-most button.
returns: 1, 2, or 3

if the --string-output option is given.

progressbar
The progress bar is a bit different, and slightly more complex
than the other controls.
It has no return value, but reads input on stdin.
It will continue to display until it reads an EOF.
Input for the progress bar is in the form:
newPercent updated text to be displayed and must
be terminated by a newline.
If you want to leave the current text intact, just provide the new
percent.
newPercent should be a number.
Examples (the first sets new text, the second leaves the old text):
26 We're now at 26%
26
In your code it would like this this: "26 We're at 26%\n". That newline is important.
Be sure to look at the examples if
you're still unclear about the progress bar.
|
Options:
| ‑‑text "initial text to display" |
This is the text that will be initially displayed. |
| ‑‑percent number |
Initial percentage, between 0 and 100, for the progress
bar |
| ‑‑indeterminate |
This option makes the progress bar an animated
"barbershop pole" (for lack of better description). It does
not indicate how far the operations you're performing have
progressed; it just shows that your application/script is
busy. You can still update the text of the label when
writing to CocoaDialog's stdin - and it doesn't
matter what percentage you feed it.
