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

58 | BUILDING
|
---|
59 | --------
|
---|
60 |
|
---|
61 | The source to F-Script Anywhere is included. It has a number of
|
---|
62 | dependencies.
|
---|
63 |
|
---|
64 | 1. Install FScript.framework (see above).
|
---|
65 |
|
---|
66 | 2. 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'.
|
---|
70 |
|
---|
71 | 3. Put a version of FScript.framework into the Source folder. This
|
---|
72 | is used for the F-Script framework auto installer.
|
---|
73 |
|
---|
74 | 4. Open 'F-Script Anywhere.xcodeproj' in Xcode and build the Application
|
---|
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.
|
---|
81 |
|
---|
82 | If you have any problems building F-Script Anywhere, please let me
|
---|
83 | know.

86 | FREQUENTLY ASKED QUESTIONS
|
---|
87 | --------------------------
|
---|
88 |
|
---|
89 | Q. What is F-Script?
|
---|
90 |
|
---|
91 | A. 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 |
|
---|
100 | Q. How do you access user interface elements?
|
---|
101 |
|
---|
102 | A. One way is to access a window and its views programmatically:
|
---|
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 |
|
---|
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'
|
---|
133 | repeatedly on container views if needed.
|
---|
134 |
|
---|
135 |
|
---|
136 | Q. ThatÕs too hard, especially all that scrolling.
|
---|
137 |
|
---|
138 | A. If you need to access a view (such as a button or text field), menu or
|
---|
139 | window, youÕre in luck. Click in an F-Script workspace window, then
|
---|
140 | click or choose ÒBrowser for TargetÉÓ from the ÒFSAÓ menu.
|
---|
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.
|
---|
143 |
|
---|
144 | The F-Script object browser now provides a similar feature: click the
|
---|
145 | ÒSelect ViewÓ button.
|
---|
146 |
|
---|
147 |
|
---|
148 | Q. I donÕt like F-ScriptÕs syntax. I don't like the object browser.
|
---|
149 | I donÕt like you either.
|
---|
150 |
|
---|
151 | A. I didnÕt write F-Script. Please address your questions to
|
---|
152 | F-ScriptÕs author or the F-Script mailing list.
|
---|
153 |
|
---|
154 | <http://www.fscript.org/contacts.htm>
|
---|
155 |
|
---|
156 | Oh, and get lost.
|
---|
157 |
|
---|
158 |
|
---|
159 | Q. My question isn't answered here.
|
---|
160 |
|
---|
161 | A. 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
|
---|
163 | <fsa@sabi.net>. I'll get back to you as soon as my schedule will
|
---|
164 | allow. Thanks!
