A lot of questions from me today. Smile

Another one is concerning matching dot (.) symbol within a name. Example how this could work:

Code:

macro MatchDot name {
     match parent =. child, name \{
                display \`parent\#'.'\#\`child, 13, 10
        \}
}

MatchDot SimpleName   ; shouldn't display anything
MatchDot Dotted.Name   ; Should display "Dotted.Name"

The example itself doesn't work, and the question is, how to make it work
(if it is possible at all).

Siberian,

It wouldn't work because «Dotted.Name» is a single token, not «Dotted»«.»«Name». You may force this with Dotted\.\Name, though (backslashes will be stripped as a step of macro expansion).

Thanks, again.
I guess, in that case I will have to use some other symbol instead of dot to divide parts of symbolic names.
Though in your example it is also possible to use space symbol instead of backslash. It works as well.

Yes, space separates symbols. You don't even need a dot in that case.
