Hi,

I want to run a TCL script by passing the script file as I invoke
tclsh, but let it stay interactively:

% tclsh script.tcl

Does someone out there know how to do this?

Thanks,

-deejay

There is probably a better way, but I just use:
% tclsh
$ source script.tcl

A simple way is to add, at the end of script.tcl, a read-eval-print
loop:

while 1 {
puts -nonewline "% "; flush stdout
gets stdin line
catch $line res
puts $res
}

Though seemingly endless, you can leave the loop with e.g. "exit" :^)

'while {[gets stdin line]>=0}' will avoid busylooping on EOF ;-)

Also, a cleaner way is to have in your .tclshrc:

if {[info exists ::env(PRESCRIPT)]} {
puts stderr "(loading $::env(PRESCRIPT))"
source $::env(PRESCRIPT)
}

And then, when you want script.tcl to be loaded on startup:

(sh family) PRESCRIPT=script.tcl tclsh
(csh family) env PRESCRIPT=script.tcl tclsh

My personal favorite is (add at the end of your script):

package require Tclx;
commandloop -async;
vwait forever;
