| 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 |
|
|---|
| [14] | 26 | F-Script Anywhere 1.1.2 was tested with FScript.framework 1.2.2
|
|---|
| 27 | (20020604) and Mac OS X 10.1.5 (5S66). It may or may not work with
|
|---|
| 28 | earlier or later versions, I don't know. If you are using an earlier
|
|---|
| 29 | F-Script version, please upgrade.

|
|---|
| 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 | When you're finished, quit the application before quitting F-Script
|
|---|
| 53 | Anywhere, otherwise the application will crash. This is an inherent
|
|---|
| 54 | limitation of the Objective-C runtime, and I can't do anything about
|
|---|
| 55 | it. F-Script Anywhere will warn you if you try to quit it when it's
|
|---|
| 56 | still installed in active applications.
|
|---|

|
|---|
| 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 |
|
|---|
| 67 | 2. Install libPatch by Ed Wynne.
|
|---|
| 68 |
|
|---|
| 69 | <http://www.phasic.com/~arwyn/libPatch-1.2.tgz>
|
|---|
| 70 |
|
|---|
| 71 | I'd suggest you do it this way:
|
|---|
| 72 |
|
|---|
| 73 | % cd /
|
|---|
| 74 | % sudo gnutar --preserve-permissions -zxf libPatch-1.2.tgz
|
|---|
| 75 | Password:
|
|---|
| 76 | (please don't use StuffIt Expander)
|
|---|
| 77 |
|
|---|
| 78 | This installs files in /Developer/Examples and
|
|---|
| 79 | /usr/local/{bin,include,lib}. If you're paranoid, you may want to
|
|---|
| 80 | check the contents of the directory before installing.
|
|---|
| 81 |
|
|---|
| 82 | Please note that the layout of the libPatch distribution has changed
|
|---|
| 83 | since libPatch 1.0; the above instructions will not work for 1.0.
|
|---|
| 84 |
|
|---|
| 85 | 3. Check out the source of 'otool' from the Darwin CVS repository.
|
|---|
| 86 | This is required because there's a bug in the function that returns
|
|---|
| 87 | the 'flavo(u)r' of an application: Cocoa, Carbon, Classic, etc.
|
|---|
| 88 | It identifies all Cocoa applications as Carbon ones. So as a
|
|---|
| 89 | workaround, F-Script Anywhere examines the application itself to
|
|---|
| 90 | see what libraries it links with. (This may fail if you're doing
|
|---|
| 91 | something weird like linking to development versions of Foundation
|
|---|
| 92 | and AppKit, but since I don't work for Apple, I couldn't test that
|
|---|
| 93 | eventuality.)
|
|---|
| 94 |
|
|---|
| 95 | Check out Commands/Apple/cctools/{include,libstuff} from Darwin
|
|---|
| 96 | CVS into the "Darwin source" directory. If you don't have a CVS
|
|---|
| 97 | account, go to <http://www.opensource.apple.com/> and get one.
|
|---|
| 98 |
|
|---|
| 99 | cd to the libstuff directory and type 'make' (it doesn't use
|
|---|
| 100 | jam/pbxbuild). I _think_ this is all you need.
|
|---|
| 101 |
|
|---|
| 102 | 4. Open 'F-Script Anywhere.pbproj' in Project Builder and build the
|
|---|
| 103 | Application target. It depends on the Library target, so you don't
|
|---|
| 104 | need to build it separately. You shouldn't see any errors or
|
|---|
| 105 | warnings, and the F-Script Anywhere application (as well as the
|
|---|
| 106 | library, which you can ignore because it is also copied into the
|
|---|
| 107 | application bundle) will appear in the build product directory.
|
|---|
| 108 |
|
|---|
| 109 | If you have any problems building F-Script Anywhere, please let me
|
|---|
| 110 | know.

| 113 | FREQUENTLY ASKED QUESTIONS
|
|---|
| 114 | --------------------------
|
|---|
| 115 |
|
|---|
| 116 | Q. What is F-Script?
|
|---|
| 117 |
|
|---|
| 118 | A. F-Script is a dialect of Smalltalk which includes a bridge to
|
|---|
| 119 | the Objective-C runtime on Mac OS X. It's open-source, and
|
|---|
| 120 | very nice. Its author, Philippe Mougin, has written several
|
|---|
| 121 | articles on it, and documentation is available from the
|
|---|
| 122 | F-Script Web site:
|
|---|
| 123 |
|
|---|
| 124 | <http://www.fscript.org/>
|
|---|
| 125 |
|
|---|
| 126 |
|
|---|
| 127 | Q. How do you access user interface elements?
|
|---|
| 128 |
|
|---|
| [14] | 129 | A. One way is to access a window and its views programmatically:
|
|---|
| [7] | 130 |
|
|---|
| 131 | > app := NSApplication sharedApplication
|
|---|
| 132 |
|
|---|
| 133 | > windows := app windows
|
|---|
| 134 |
|
|---|
| 135 | > windows
|
|---|
| 136 | NSCFArray {<NSWindow: 0x186770>, <NSWindow: 0x1ba4a0>, <NSWindow:
|
|---|
| 137 | 0x1f0cea0>}
|
|---|
| 138 |
|
|---|
| 139 | > windows collect: [:each | each title]
|
|---|
| 140 |
|
|---|
| 141 | error: an instance of NSWindow does not respond to "collect:"
|
|---|
| 142 |
|
|---|
| 143 | (...a gentle reminder that this is not Smalltalk...)
|
|---|
| 144 |
|
|---|
| 145 | > windows title
|
|---|
| 146 | {'F-Script', '', ''}
|
|---|
| 147 |
|
|---|
| 148 | (...but F-Script has some tricks of its own...)
|
|---|
| 149 |
|
|---|
| 150 | > fsw := windows at: 0
|
|---|
| 151 |
|
|---|
| 152 | > fswView := fsw contentView
|
|---|
| 153 |
|
|---|
| [14] | 154 | To open an F-Script object browser on fswView, type:
|
|---|
| 155 |
|
|---|
| 156 | > sys browse: fswView
|
|---|
| 157 |
|
|---|
| 158 | Or, click ÒNew Browser: Object...Ó, then click on fswView.
|
|---|
| 159 | Click 'subviews' in the message list. You can use 'subviews'
|
|---|
| [7] | 160 | repeatedly on container views if needed.
|
|---|
| 161 |
|
|---|
| 162 |
|
|---|
| [14] | 163 | Q. ThatÕs too hard, especially all that scrolling.
|
|---|
| [7] | 164 |
|
|---|
| [14] | 165 | A. If you need to access a view (such as a button or text field) or
|
|---|
| 166 | window, youÕre in luck. Click in an F-Script workspace window, then
|
|---|
| 167 | choose ÒAssociate With InterfaceÓ from the ÒFSAÓ menu.
|
|---|
| 168 | Follow the instructions in the window to select a user interface
|
|---|
| 169 | element, view it in an object browser or assign it to a variable.
|
|---|
| [7] | 170 |
|
|---|
| 171 |
|
|---|
| [14] | 172 | Q. F-Script Anywhere fails miserably on Jaguar.
|
|---|
| 173 |
|
|---|
| 174 | A. So IÕve heard (I donÕt have access to Jaguar developer seeds). This
|
|---|
| 175 | is an issue with libPatch, and affects far more than F-Script Anywhere.
|
|---|
| 176 | Default Folder X and UnsanityÕs haxies are similarly rendered useless.
|
|---|
| 177 | A Jaguar-compatible replacement for libPatch is under development,
|
|---|
| 178 | but it does not yet contain support for applications such as F-Script
|
|---|
| 179 | Anywhere (which is unique in its use of libPatch). IÕll fix this
|
|---|
| 180 | as soon as it does.
|
|---|
| 181 |
|
|---|
| 182 |
|
|---|
| 183 | Q. I don't like F-ScriptÕs syntax. I don't like the object browser.
|
|---|
| [7] | 184 | I don't like you either.
|
|---|
| 185 |
|
|---|
| [14] | 186 | A. I didnÕt write F-Script. Please address your questions to
|
|---|
| 187 | F-ScriptÕs author or the F-Script mailing list.
|
|---|
| [7] | 188 |
|
|---|
| 189 | <http://www.fscript.org/contacts.htm>
|
|---|
| 190 |
|
|---|
| 191 | Oh, and get lost.
|
|---|
| 192 |
|
|---|
| 193 |
|
|---|
| 194 | Q. My question isn't answered here.
|
|---|
| 195 |
|
|---|
| 196 | A. That's not a question. But if you have a question about F-Script
|
|---|
| 197 | Anywhere, a suggestion or a bug to report, please email it to me at
|
|---|
| 198 | <fsa@sabi.net>. Please try to keep your messages short and to the
|
|---|
| 199 | point, and I'll get back to you as soon as my schedule will allow.
|
|---|
| 200 | Thanks!
