​Me too. And I couldn't remember one to save. But sometimes I look at an ID
field in record A then glance over to something else to verify things
happened the way I wanted them to. And in that instant I'm really looking
at the first or last few characters. Lowercase chars mixed with numbers
have more distinctive patterns than when it's all uppercase. ​

I’m curious why you want to “read” a UUID? I can’t read one and remember it 
with or without lowercase characters. It’s just too long.

My use of UUIDs is primarily for primary keys. And in those situations where I 
need to do some debugging and have to query on a UUID to find something, I have 
this object method for the UUID field on an input form:

  // copy UUID to pasteboard if Mouse Enter and Shift Key down
If ((Form event=On Mouse Enter) & Shift down)
SET TEXT TO PASTEBOARD(Self->)
BEEP
End if 

Then I don’t have to read it or remember it and it is on the pasteboard ready 
for me to paste into the Query Editor.

Re: Why does 4D have uppercase UUIDs?

2017-04-24 Thread Lee Hinde via 4D_Tech 
python -c 'import uuid; print uuid.uuid4()'

returns: 

8f1dad2d-2eec-4da7-b484-63a7e7549824

Not that that’s canonical, just offering another sample.

> uppercase-non-hyphenated seems like a reasonable cross-platform solution

Nicely put :)

Upper/Lower with or without dashes, under the hood it is a 128 bit integer, the 
letters and numbers are just the number in Hex (i.e. it doesn't make a 
difference on the case)

Even Wiki says upper or lower case

Re: Why does 4D have uppercase UUIDs?

2017-04-23 Thread Keisuke Miyako via 4D_Tech 
I wasn't aware of the argument that they should always be lowercase.

it's true that the native function on Windows (UuidCreate, UuidToString) 
creates lowercase,
but on Mac (NSUUID.UUIDString, CFUUIDCreate/CFUUIDCreateString) they are 
uppercase and also hyphenated.

uppercase-non-hyphenated seems like a reasonable cross-platform solution.

Agree, I prefer Ioda.

me: 
wondering why uuid are uppercase and md5 lowercase…
UPPERCASE IS UGLY, IT YELLS

me (again):
BTW a uuid field is perfect to store a md5

Bruno:
to help differentiate between a uuid and a md5  :-)))

me:
so clever. 
I was thinking the uuid guy at 4D shouts to be paid better while the md5 one is 
shy.
