Hi all.
How do I get the leading zero using this in a attribute creator?
[format "#%06X" [expr {int(rand() * 0xFFFFFF)}]]
(a random uppercase hex creator to create random hex colors in range )
I get this "# D7A01" when it occurs. The location for the "0" is now a space.
btw. Stringreplace is of no use, the value can then not be parsed anymore. (I tried of course.)
Hi @gio, why not use FME functions?

#@Format(%06X,@Evaluate(@int(@rand()*0xFFFFFF)))
format "#%06X" [expr int(rand() * 0xFFFFFF)]
Hi @takashi
Those are the same functions afaik, tcl, wrapped probably. Maybe it is not wrapped correctly?
The hash tag needs to stay in the format string.
I am just wondering why the 0-padding does not work. Or if anyone can hint at why.
Like I said, the spot for the zero gets occupied by a space when I use the expression.
TCL caller, or using testers, creators etc. to use tcl expressions should work. But the missing leading "0" is an obvious bug it seems.
Using the wrapped functions (what you call fme functions) and using the TCL caller to execute the tcl expression, do yield the "0".
Also using
[regexp {^#?([A-F0-9]{2})([A-F0-9]{2})([A-F0-9]{2})$} )} AM r g b ]!=0?$r:0
Fails on some of the hex pairs, while the expression works 100% using rubular or any other online expression evaluators.
Whilst using a stringsearcher with the same regexp works on all found instances.
To me this indicates a bug.

In use of the FME @Format function, the hash character can be put either front of entire expression or front of the format string. Both return the same result in this case.
