Due to some problems with it (bug 396051 as well as bug 399242) I think we should not include the scriptable IO apis in 1.9. The former bug describes some api issues that I think are more important to fix before people start to use it and I would rather have better more robust APIs that have to fix issues with it later.

Comment on attachment 300414 [details] [diff] [review] back out patch a=beltzner, fixes a beta3 blocker

So did this broke context menus? Failed to load XPCOM component: /home/smaug/mozilla/mozilla_cvs/mozilla/ff_build/dist/bin/components/nsScriptableIO.js Error: IO is not defined Source File: chrome://browser/content/utilityOverlay.js Line: 450

Hmmm. Looks like there's a bunch of places where IO.newURI was being used. We should either just unbackout IO again or fix up the newURI calls to use the IOService instead.

Until bug 415218 is fixed, Gavin requested that I back out the back out so that nightlies aren't completely broken for everybody. When this gets backed out again for good, please remember to remove xpcom/io/nsIScriptableStreams.idl and add components/nsScriptableIO.js to browser/installer/removed-files.in and family.

I backed out the back out of the back out.

I found at least 1 extension (ClipMarks) that was broke with this change. Not critical, but I will do some evangelism on it and mark it as a compatibility issue.

I guess the documentation that was added for bug 380813 should be reverted, or at least marked as "not in Firefox 3"?

I've added a warning to the documentation for nsIScriptableIO that it has been removed from Firefox.

Hi, I'm new here and need some help. It looks like xulrunner-1.9bpre4 no longer has nsIScriptableIO API. I'm running prism-0.8 which has this line: IO.getFile("Profile", null) That now throws "IO not defined". This thread seems to suggest nsIScriptableIO is being phased out, so what's the new alternative? Thanks!

You actually need to use the "old" ways. See the code snippets here: http://developer.mozilla.org/en/docs/Code_snippets:File_I/O#Getting_special_files You want the "ProfD" folder.
