NSLog problem with PB6

[deseven]

This worked before 6.00 and C backend, but now it outputs garbage for some reason:

Code: Select all

ImportC ""
  NSLog(format,message)
EndImport

Define format = CocoaMessage(0,0,"NSString stringWithString:$",@"%S")
Define message = CocoaMessage(0,0,"NSString stringWithString:$",@"test 123")
NSLog(format,message)

To see system logs, open Console app, press "Start" on top, input "PureBasic" in the search field, then run the code above.

I also tried using stringWithUTF8String and passing pointer to PB string directly - it all produces various types of garbage or invalid memory access.

Can anyone help?

Code: Select all

ImportC ""
  NSLog(format,message)
EndImport

Define format = CocoaMessage(0,0,"NSString stringWithString:$",@"%S")
Define message = CocoaMessage(0,0,"NSString stringWithString:$",@"test 123")


NSLog(format, @message)

This outputs "\^B" to the system log (instead of "test 123").

check it

Code: Select all

;-TOP

Macro CocoaString(NSString)
  PeekS(CocoaMessage(0, NSString, "UTF8String"), -1, #PB_UTF8)
EndMacro

ImportC ""
  NSLog(format,message)
EndImport

Define format = CocoaMessage(0,0,"NSString stringWithString:$",@"%@") ; <- NSString %@, UTF8String %s
Define message = CocoaMessage(0,0,"NSString stringWithString:$",@"test 123")
Debug CocoaString(format)
Debug CocoaString(message)

NSLog(format, message)

Define *message = UTF8("Hello World!")
Define format2 = CocoaMessage(0,0,"NSString stringWithString:$",@"%s") ; <- NSString %@, UTF8String %s
NSLog(format2, *message)

This Works too

Code: Select all

ImportC "-framework CoreFoundation"
  CFStringCreateWithCString(alloc, cStr.p-utf8, encoding = $8000100)
EndImport

ImportC ""
  NSLog(format, message)
EndImport


Define format = CFStringCreateWithCString(0, "%S")
Define message.s = "test 123"


NSLog(format, @message)

Encoding constants already defined

Code: Select all

ImportC "-framework CoreFoundation"
  CFStringCreateWithCString(alloc, cStr.p-utf8, encoding = #kCFStringEncodingUTF8)
EndImport

Hm... None of your solutions worked for me.

The one by Wolfram writes garbage to the system log.
The one by mk-soft gives me IMA (first NSLog call, so I commented it out) and also writes garbage (second NSLog call).

Do they work for you? I wonder what's the difference between our systems. I'm on 6.00 LTS macOS 11.6.5 by the way.

[Wolfram]

Yes, my second post is tested
PB6.beta7, macOS Catalina.

[deseven]

Could it be OS/compiler related then? Here's what I see with your code:

[mk-soft]

macOS v12.3.1

Code: Select all

Macro CocoaString(NSString)
  PeekS(CocoaMessage(0, NSString, "UTF8String"), -1, #PB_UTF8)
EndMacro

Macro CocoaCString(NSString)
  PeekS(CocoaMessage(0, NSString, "cStringUsingEncoding:", #NSUTF16LittleEndianStringEncoding))
EndMacro

Macro CocoaAllocString(String)
  CocoaMessage(0, 0, "NSString stringWithBytes:", @String, "length:", StringByteLength(String), "encoding:", #NSUTF16LittleEndianStringEncoding)
EndMacro

ImportC ""
  NSLog(format, message)
EndImport
Define format = CocoaAllocString("Output: %S")
Define message.s = "test 123"

Debug CocoaCString(format)

NSLog(format, @message)

[deseven]

And this one gives me "Output: %garbage%"

[mk-soft]

Works here with High Sierra v10.13.6 (VM) and Monterey v12.3.1 (Host)

Console:

standard 14:28:43.374138+0200 PureBasic.0 Output: Test: 14:28:43

Code: Select all

Macro CocoaString(NSString)
  PeekS(CocoaMessage(0, NSString, "UTF8String"), -1, #PB_UTF8)
EndMacro

Macro CocoaCString(NSString)
  PeekS(CocoaMessage(0, NSString, "cStringUsingEncoding:", #NSUTF16LittleEndianStringEncoding))
EndMacro

Macro CocoaAllocString(String)
  CocoaMessage(0, 0, "NSString stringWithBytes:", @String, "length:", StringByteLength(String), "encoding:", #NSUTF16LittleEndianStringEncoding)
EndMacro

ImportC ""
  NSLog(format, message)
EndImport

Define format = CocoaAllocString("Output: %S")
Define message.s = "Test: " + FormatDate("%HH:%II:%SS", Date())

NSLog(format, @message)

[deseven]

And this code always gives me "Output: \^B", even though the Date() is obviously changing.
Thanks guys, I guess there's something wrong with my system, I'll test on other machines to see if it works.

[deseven]

Ok, looks like this happens only with arm/aarch64 compiler, x86_64 works fine (tested on Catalina and Big Sur). Can anyone who has M1-based machine try it as well, just to confirm?

[deseven]

Still no one with M1/M2 who can test it?
