10WHAT IS IT?
11-----------
12
[14]13Ever wanted to inspect a Cocoa applicationÕs objects from the inside?
[7]14Frustrated with using GDB to debug Objective-C?
15
16You need F-Script Anywhere! (with apologies to Guido van Rossum)
17
18
19INSTALLATION
20------------
21
22Install F-Script; you can download it at <http://www.fscript.org/>.
23In particular, make sure the framework is installed in a Frameworks
24directory, such as /Library/Frameworks or ~/Library/Frameworks.
25
[409]26F-Script Anywhere 2.0d2 was tested with FScript.framework 2.0a2 and
27Mac OS X 10.5.2 (9C31). If you are using an earlier F-Script version,
28please upgrade. F-Script Anywhere 2.0 requires Mac OS X 10.5 or
29later; if you're using Mac OS X 10.4, download F-Script 1.3.5
30(20070421) which includes F-Script Anywhere 1.3.
[7]31
32USAGE
33-----
34
35Open the F-Script Anywhere application. Pick a Cocoa application from
36the list and click Install or press return. F-Script Anywhere will
37either install itself in that application, give you an error message,
38or crash. (Hopefully not the latter!)
39
40Switch to the application, and you should find a ÒFSAÓ menu there.
41Select ÒNew F-Script WorkspaceÓ to display a F-Script workspace.
42This behaves like any other workspace, except it's executing within
43the context of the application.
44
45You can also install F-Script Anywhere by using its dock menu. If
46the frontmost application is a Cocoa application, just pick ÒInstallÉÓ
47from the menu and F-Script Anywhere will install in that application.
48If F-Script Anywhere canÕt install, the menu item will tell you so,
49or F-Script AnywhereÕs icon will bounce to indicate a pending sheet
50explaining the problem.
51
[153]52To remove F-Script Anywhere from an application, quit the application.
53Because of limitations in Apple's Objective-C runtime, it is
54impossible to remove F-Script Anywhere while the application is
55running.

58BUILDING
59--------
60
61The source to F-Script Anywhere is included. It has a number of
62dependencies.
63
641. Install FScript.framework (see above).
65
[409]662. In the "Darwin source" directory, check out Darwin's cctools from
67 <http://www.opensource.apple.com/>, untar it and rename the
68 directory to "cctools". cd to the libstuff directory and type
69 'make RC_CFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc" RC_XBS=YES dynamic'.
[7]70
[409]713. Put a version of FScript.framework into the Source folder. This
72 is used for the F-Script framework auto installer.
[229]73
[409]744. Open 'F-Script Anywhere.xcodeproj' in Xcode and build the Application
[153]75 target. This target depends on the Bundle and Bundle Loader
76 targets, so you don't need to build them separately. You
77 shouldnÕt see any errors or warnings, and the F-Script Anywhere
78 application (as well as two bundles, which you can ignore because
79 they are copied into the application bundle) will appear in the
80 build product directory.
[7]81
82If you have any problems building F-Script Anywhere, please let me
83know.

86FREQUENTLY ASKED QUESTIONS
87--------------------------
88
89Q. What is F-Script?
90
91A. F-Script is a dialect of Smalltalk which includes a bridge to
92 the Objective-C runtime on Mac OS X. It's open-source, and
93 very nice. Its author, Philippe Mougin, has written several
94 articles on it, and documentation is available from the
95 F-Script Web site:
96
97 <http://www.fscript.org/>
98
99
100Q. How do you access user interface elements?
101
[14]102A. One way is to access a window and its views programmatically:
[7]103
104 > app := NSApplication sharedApplication
105
106 > windows := app windows
107
108 > windows
109 NSCFArray {<NSWindow: 0x186770>, <NSWindow: 0x1ba4a0>, <NSWindow:
110 0x1f0cea0>}
111
112 > windows collect: [:each | each title]
113
114 error: an instance of NSWindow does not respond to "collect:"
115
116 (...a gentle reminder that this is not Smalltalk...)
117
118 > windows title
119 {'F-Script', '', ''}
120
121 (...but F-Script has some tricks of its own...)
122
123 > fsw := windows at: 0
124
125 > fswView := fsw contentView
126
[14]127 To open an F-Script object browser on fswView, type:
128
129 > sys browse: fswView
130
131 Or, click ÒNew Browser: Object...Ó, then click on fswView.
132 Click 'subviews' in the message list. You can use 'subviews'
[7]133 repeatedly on container views if needed.
134
135
[14]136Q. ThatÕs too hard, especially all that scrolling.
[7]137
[16]138A. If you need to access a view (such as a button or text field), menu or
[14]139 window, youÕre in luck. Click in an F-Script workspace window, then
[409]140 click or choose ÒBrowser for TargetÉÓ from the ÒFSAÓ menu.
[14]141 Follow the instructions in the window to select a user interface
142 element, view it in an object browser or assign it to a variable.
[7]143
[153]144 The F-Script object browser now provides a similar feature: click the
[409]145 ÒSelect ViewÓ button.
[7]146
[14]147
[16]148Q. I donÕt like F-ScriptÕs syntax. I don't like the object browser.
149 I donÕt like you either.
150
[14]151A. I didnÕt write F-Script. Please address your questions to
152 F-ScriptÕs author or the F-Script mailing list.
[7]153
154 <http://www.fscript.org/contacts.htm>
155
156 Oh, and get lost.
157
158
159Q. My question isn't answered here.
160
161A. That's not a question. But if you have a question about F-Script
162 Anywhere, a suggestion or a bug to report, please email it to me at
[409]163 <fsa@sabi.net>. I'll get back to you as soon as my schedule will
164 allow. Thanks!
