PB5.42b1 ":" in Enumerations (tiny bug)

PureBasic 5.42 Beta 1 (x86/x64) on Windows 7
Using ":" as a line separator in an Enumeration will make PureBasic complain under some rare circumstances.
PureBasic wrote:Line 3: Only constants are allowed in an Enumeration.
Code: Select all
Enumeration NotWorking
#anna
:
#berta
EndEnumeration
Enumeration WorksFine
#foo
#bar : #barossa
#boo
EndEnumeration
Enumeration WhyImUsingIt
#bla
: ; ":" makes this comment shiftable with crtl+e to make
#bli ; it a nice looking block comment, but doesn't work...
#blub
EndEnumeration
I know, that this is located somewhere on the borderline between bug and feature request.
I posted this in the bug section because it is actually correct PureBasic syntax, although it's usage and the need for it may be a topic for a discussion.

Honestly I think your desire to use ':' in this manner is a bit absurd. It is used to combine two code lines into one physical line. You are using it to separate two physical lines.
In your code you write:
; ":" makes this comment shiftable with crtl+e to make
; it a nice looking block comment, but doesn't work...
If you leave out the ':' on the line by itself everything still works fine using [ctrl+e] to line things up. If you are re-indenting the lines using [ctrl+i] then you will run into problems.
If you first line things up with [ctrl+e] then add a ';' where you would of previously put the ':' it can function the same way, as long as you don't use [ctrl+e] on those lines again.
I think what you describe as your need could be done with a new 'NOP' (no operation) function to put on the line instead. It would be something that doesn't compile but holds the space and keep it aligned.
How about this?
Code: Select all
;Choose your macro name wisely ;)
Macro __
EndMacro
Enumeration WhyImUsingIt
#bla
__ ; ":" makes this comment shiftable with crtl+e to make
#bli ; it a nice looking block comment, but doesn't work...
#blub
EndEnumeration
UndefineMacro __ ;If you only need it for enumerations it's not a bad idea to remove it afterwards.
I do think this falls in line (pun intended) with being a feature request instead of being a bug report.

So Demivec, I mostly agree with your posting. The core statement is just that it's correct PureBasic syntax and therefore a (tiny) bug. Maybe there's a deeper problem hidden with ":" as line separator... or maybe not... who knows...
Thanks for the nice idea with the NOP macro! It's a useful way around this little problem.

Actually, it's not. As mentioned, you can't use a colon by itself on a line because you're not separating multiple commands on the same line with it, which is what the manual says it's for:
PureBasic Manual wrote:Any number of commands can be added to the same line by using the : option.
So, the way you're using it is incorrect PureBasic syntax.
