Re: Points vs pixels in a bash script
Just as an aside, points are not Apple-specifc. They are a typesetting unit equivalent to 1/72 of an inch. It's the same unit used for font sizes. -jeff On Mon, Jun 8, 2020 at 2:43 PM Gabriel Zachmann via Cocoa-dev < cocoa-dev@lists.apple.com> wrote: > I know this mailing list might not be the perfect fit for my question, > but maybe someone has an idea. > > I have a problem converting points (I think) to pixels in a bash script. > I'd rather not write an extra C/Cocoa utility for that. > > Using >system_profiler SPDisplaysDataType > I can retrieve the size of a Mac's display in pixels. > > However, the command > >tell application "System Events" to get the size of every window of > every process > > (which I execute from my bash script using osascript) apparently does NOT > return window sizes in pixels.

What is the preferred way to set NSTextView content from NSAttributedString?
Situation: - I am working in Swift 5. - I have an instance of an NSTextView. (Call it "V") - The value has already been set once. (Call this value "T1") - V is showing T1. - I have an NSAttributedString from another source. (Call this value "T2") Desired goal: - I want to set the displayed contents of V to T2. What is/are the recommended way/s to do this? *I would hope that I could assign V.attributedString = T2, but alas the world does not seem to be this simple.* Thanks in advance. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Preferred methods for usig NSOutlineView
I've been playing around with the NSOutlineView, and as seems to be the usual case, the documentation from Apple is seriously deficient. I've been trying to use bindings to a tree controller, but I'm having difficulty getting element selection to work. I'm guessing that this would be done by binding to the tree controller using "Selection Index Paths (...)", but exactly what needs to be done there is unclear. Is there a worked-through example using interface builder and outlineview-treecontroller bindings, or should I give up on bindings and start using NSOutlineViewDelegate and rampant NSOutlineView subclassing? -jeff ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Difficulties with recovering NSAttributedString attachments from saved RTFD
So, I replaced...
*let* recoveredString = NSMutableAttributedString(rtfd: savedRtfd,
documentAttributes: *nil*)!
...with...
*let* fw = FileWrapper(serializedRepresentation: savedRtfd)!
*let* filePath = URL(fileURLWithPath: "/tmp/bar")
*do* {
*try* fw.write(
to: filePath,
options: [FileWrapper.WritingOptions.atomic],
originalContentsURL: *nil*)
} *catch* {
print("Error info: \(error)")
XCTFail()
}
*let* recoveredString = NSMutableAttributedString(rtfdFileWrapper:
fw, documentAttributes: *nil*)!
The RTFD gets unpacked into /tmp/bar/..., and I can see the file with the
appropriate contents:
> cat /tmp/bar/Attachment.txt
foobar
>
*Bad News*
recoveredAttachment.contents is still nil.
*Good News*
Going through the attachment's file wrapper works:
let recoveredContents = recoveredAttachment.fileWrapper?.
regularFileContents
XCTAssertEqual(String(data: recoveredContents!, encoding: .utf8),
"foobar")
*Even Better News*
Going through the attachment's file wrapper works when using the original
code. (!!)
*Conclusion*
NSTextAttachment.contents seems to be broken, deeply misleading, or (most
likely) some other magic is required to get it to read its contents.
Thank you for pointing me in the right direction Gary.

Difficulties with recovering NSAttributedString attachments from saved RTFD
I am having some difficulty with saving NSAttributedStrings as RTFD and
then recovering
them with attachments intact. I generate a string containing an attachment
and turn that into
RTFD. When I turn that RTFD back into an NSAttributedString, I get the
.string back, and I
get an attachment, but the attachment's .contents is empty.
This is the smallest example I can come up with:
func testSaveAndRestoreAttachment() {
// Build up the string "deadbeefdeadbeef"
let originalContent = "foobar".data(using: .utf8)
let originalAttachment = NSTextAttachment(
data: originalContent, ofType: "public.plain-text")
let originalString = NSMutableAttributedString(string: "deadbeef")
originalString.append(NSMutableAttributedString(attachment:
originalAttachment))
originalString.append(NSMutableAttributedString(string: "deadbeef")
// save string as RTFD (note that generated RTFD contains "foobar"
inside.)
let savedRtfd = originalString.rtfd(from:
NSRange(0.. Array {
var attachments: Array = []
s.enumerateAttribute(.attachment, in: NSRange(0..https://lists.apple.com/mailman/options/cocoa-dev/archive%40mail-archive.com
