TCL question: count occurrence of a character ...

[Peter Danecek]

Hi all,

I would like to count the occurrences of a character, more specifically of the `.` in the ${version} option. Asking Big Brother Google, there seem to be quite some possibilities, so I came up with the following solutions:

set dot_count       [ regsub -all "\\." ${version} {} ignore ]

but I do not like it particularly and I am wondering if there would be a more elegant expression you would propose.

Thanks!
