Re: [naviserver-devel] Proposal: just an idea about config syntax

[Brett S. <bre...@ya...>]

I always wondered if Tcl's namespace mechanism could have been used for the=
 config file, and by your example below, it is tending towards that. Again,=
 the idea would be to utilize, where possible, existing Tcl mechanisms. So,=
 something like:=0A=0Anamespace eval fastpath {=0A      set cache          =
          false=0A      set cachemaxsize        5120000=0A      set cachema=
xentry       512000=0A      set mmap                    false=0A}=0A=0A .=
=0A .=0A .=0A=0Anamespace eval server::${servername} {=0A     set connspert=
hread          0=0A     set flushcontent            false=0A     set maxcon=
nections          100=0A     set maxthreads              10=0A     set mint=
hreads              0=0A     set threadtimeout           120=0A}=0A=0AWhat'=
s good about this as well, is if you needed to access that variable later o=
n in the config file, then you could just use the FQ name, i.e.=0A=0A  set =
some_val [$fastpath::cache]=0A=0A=0AHaven't really thought this all the way=
 through, so there might be some pitfalls.=0A=0AJust an idea,=0A=0A    --br=
