| 10 | WHAT IS IT?
|
|---|
| 11 | -----------
|
|---|
| 12 |
|
|---|
| [14] | 13 | Ever wanted to inspect a Cocoa applicationÕs objects from the inside?
|
|---|
| [7] | 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 |
|
|---|
| [153] | 26 | F-Script Anywhere 1.2 was tested with FScript.framework 1.2.5
|
|---|
| 27 | (20031020) and Mac OS X 10.3.2 (7D24). If you are using an earlier
|
|---|
| 28 | F-Script version, please upgrade. F-Script Anywhere 1.2 should also
|
|---|
| 29 | work with Mac OS X 10.2.x, but will not work with Mac OS X 10.1 or
|
|---|
| 30 | earlier: please use F-Script Anywhere 1.1.5 instead.
|
|---|
| [7] | 31 |
|
|---|
| 32 |
|
|---|
| 33 | USAGE
|
|---|
| 34 | -----
|
|---|
| 35 |
|
|---|
| 36 | Open the F-Script Anywhere application. Pick a Cocoa application from
|
|---|
| 37 | the list and click Install or press return. F-Script Anywhere will
|
|---|
| 38 | either install itself in that application, give you an error message,
|
|---|
| 39 | or crash. (Hopefully not the latter!)
|
|---|
| 40 |
|
|---|
| 41 | Switch to the application, and you should find a ÒFSAÓ menu there.
|
|---|
| 42 | Select ÒNew F-Script WorkspaceÓ to display a F-Script workspace.
|
|---|
| 43 | This behaves like any other workspace, except it's executing within
|
|---|
| 44 | the context of the application.
|
|---|
| 45 |
|
|---|
| 46 | You can also install F-Script Anywhere by using its dock menu. If
|
|---|
| 47 | the frontmost application is a Cocoa application, just pick ÒInstallÉÓ
|
|---|
| 48 | from the menu and F-Script Anywhere will install in that application.
|
|---|
| 49 | If F-Script Anywhere canÕt install, the menu item will tell you so,
|
|---|
| 50 | or F-Script AnywhereÕs icon will bounce to indicate a pending sheet
|
|---|
| 51 | explaining the problem.
|
|---|
| 52 |
|
|---|
| [153] | 53 | To remove F-Script Anywhere from an application, quit the application.
|
|---|
| 54 | Because of limitations in Apple's Objective-C runtime, it is
|
|---|
| 55 | impossible to remove F-Script Anywhere while the application is
|
|---|
| 56 | running.

|
|---|
| 59 | BUILDING
|
|---|
| 60 | --------
|
|---|
| 61 |
|
|---|
| 62 | The source to F-Script Anywhere is included. It has a number of
|
|---|
| 63 | dependencies.
|
|---|
| 64 |
|
|---|
| 65 | 1. Install FScript.framework (see above).
|
|---|
| 66 |
|
|---|
| [153] | 67 | 2. Check out the source of 'otool' from the Darwin CVS repository.
|
|---|
| [7] | 68 | This is required because there's a bug in the function that returns
|
|---|
| 69 | the 'flavo(u)r' of an application: Cocoa, Carbon, Classic, etc.
|
|---|
| 70 | It identifies all Cocoa applications as Carbon ones. So as a
|
|---|
| 71 | workaround, F-Script Anywhere examines the application itself to
|
|---|
| 72 | see what libraries it links with. (This may fail if you're doing
|
|---|
| 73 | something weird like linking to development versions of Foundation
|
|---|
| 74 | and AppKit, but since I don't work for Apple, I couldn't test that
|
|---|
| 75 | eventuality.)
|
|---|
| 76 |
|
|---|
| 77 | Check out Commands/Apple/cctools/{include,libstuff} from Darwin
|
|---|
| 78 | CVS into the "Darwin source" directory. If you don't have a CVS
|
|---|
| 79 | account, go to <http://www.opensource.apple.com/> and get one.
|
|---|
| 80 |
|
|---|
| 81 | cd to the libstuff directory and type 'make' (it doesn't use
|
|---|
| 82 | jam/pbxbuild). I _think_ this is all you need.
|
|---|
| 83 |
|
|---|
| [153] | 84 | 3. Open 'F-Script Anywhere.pbproj' in Xcode and build the Application
|
|---|
| 85 | target. This target depends on the Bundle and Bundle Loader
|
|---|
| 86 | targets, so you don't need to build them separately. You
|
|---|
| 87 | shouldnÕt see any errors or warnings, and the F-Script Anywhere
|
|---|
| 88 | application (as well as two bundles, which you can ignore because
|
|---|
| 89 | they are copied into the application bundle) will appear in the
|
|---|
| 90 | build product directory.
|
|---|
| [7] | 91 |
|
|---|
| 92 | If you have any problems building F-Script Anywhere, please let me
|
|---|
| 93 | know.

| 96 | FREQUENTLY ASKED QUESTIONS
|
|---|
| 97 | --------------------------
|
|---|
| 98 |
|
|---|
| 99 | Q. What is F-Script?
|
|---|
| 100 |
|
|---|
| 101 | A. F-Script is a dialect of Smalltalk which includes a bridge to
|
|---|
| 102 | the Objective-C runtime on Mac OS X. It's open-source, and
|
|---|
| 103 | very nice. Its author, Philippe Mougin, has written several
|
|---|
| 104 | articles on it, and documentation is available from the
|
|---|
| 105 | F-Script Web site:
|
|---|
| 106 |
|
|---|
| 107 | <http://www.fscript.org/>
|
|---|
| 108 |
|
|---|
| 109 |
|
|---|
| 110 | Q. How do you access user interface elements?
|
|---|
| 111 |
|
|---|
| [14] | 112 | A. One way is to access a window and its views programmatically:
|
|---|
| [7] | 113 |
|
|---|
| 114 | > app := NSApplication sharedApplication
|
|---|
| 115 |
|
|---|
| 116 | > windows := app windows
|
|---|
| 117 |
|
|---|
| 118 | > windows
|
|---|
| 119 | NSCFArray {<NSWindow: 0x186770>, <NSWindow: 0x1ba4a0>, <NSWindow:
|
|---|
| 120 | 0x1f0cea0>}
|
|---|
| 121 |
|
|---|
| 122 | > windows collect: [:each | each title]
|
|---|
| 123 |
|
|---|
| 124 | error: an instance of NSWindow does not respond to "collect:"
|
|---|
| 125 |
|
|---|
| 126 | (...a gentle reminder that this is not Smalltalk...)
|
|---|
| 127 |
|
|---|
| 128 | > windows title
|
|---|
| 129 | {'F-Script', '', ''}
|
|---|
| 130 |
|
|---|
| 131 | (...but F-Script has some tricks of its own...)
|
|---|
| 132 |
|
|---|
| 133 | > fsw := windows at: 0
|
|---|
| 134 |
|
|---|
| 135 | > fswView := fsw contentView
|
|---|
| 136 |
|
|---|
| [14] | 137 | To open an F-Script object browser on fswView, type:
|
|---|
| 138 |
|
|---|
| 139 | > sys browse: fswView
|
|---|
| 140 |
|
|---|
| 141 | Or, click ÒNew Browser: Object...Ó, then click on fswView.
|
|---|
| 142 | Click 'subviews' in the message list. You can use 'subviews'
|
|---|
| [7] | 143 | repeatedly on container views if needed.
|
|---|
| 144 |
|
|---|
| 145 |
|
|---|
| [14] | 146 | Q. ThatÕs too hard, especially all that scrolling.
|
|---|
| [7] | 147 |
|
|---|
| [16] | 148 | A. If you need to access a view (such as a button or text field), menu or
|
|---|
| [14] | 149 | window, youÕre in luck. Click in an F-Script workspace window, then
|
|---|
| 150 | choose ÒAssociate With InterfaceÓ from the ÒFSAÓ menu.
|
|---|
| 151 | Follow the instructions in the window to select a user interface
|
|---|
| 152 | element, view it in an object browser or assign it to a variable.
|
|---|
| [7] | 153 |
|
|---|
| [153] | 154 | The F-Script object browser now provides a similar feature: click the
|
|---|
| 155 | "Select view" button.
|
|---|
| [7] | 156 |
|
|---|
| [14] | 157 |
|
|---|
| [16] | 158 | Q. I donÕt like F-ScriptÕs syntax. I don't like the object browser.
|
|---|
| 159 | I donÕt like you either.
|
|---|
| 160 |
|
|---|
| [14] | 161 | A. I didnÕt write F-Script. Please address your questions to
|
|---|
| 162 | F-ScriptÕs author or the F-Script mailing list.
|
|---|
| [7] | 163 |
|
|---|
| 164 | <http://www.fscript.org/contacts.htm>
|
|---|
| 165 |
|
|---|
| 166 | Oh, and get lost.
|
|---|
| 167 |
|
|---|
| 168 |
|
|---|
| 169 | Q. My question isn't answered here.
|
|---|
| 170 |
|
|---|
| 171 | A. That's not a question. But if you have a question about F-Script
|
|---|
| 172 | Anywhere, a suggestion or a bug to report, please email it to me at
|
|---|
| 173 | <fsa@sabi.net>. Please try to keep your messages short and to the
|
|---|
| 174 | point, and I'll get back to you as soon as my schedule will allow.
|
|---|
| 175 | Thanks!
