how to call a tcl file from another tcl file
To call or execute a Tcl script from another Tcl script, you can use the source
command. The source
command reads and evaluates the content of the specified Tcl script file. Here's how you can use it:
Assuming you have two Tcl script files named script1.tcl
and script2.tcl
, and you want to call script2.tcl
from script1.tcl
, follow these steps:
script1.tcl:
tcl# Contents of script1.tcl
puts "Executing script1.tcl"
source "script2.tcl"
script2.tcl:
tcl# Contents of script2.tcl
puts "Executing script2.tcl"
In this example, when you execute script1.tcl
, it will print "Executing script1.tcl" and then use the source
command to execute script2.tcl
, which will print "Executing script2.tcl".
To run the script1.tcl
file, you can execute it using the Tcl interpreter in your terminal or Tcl environment:
shtclsh script1.tcl
This will execute script1.tcl
and, in turn, execute script2.tcl
.
Remember that the source
command reads and evaluates the content of the specified Tcl script file in the context of the current script. This means that variables and commands from the called script will be accessible in the calling script, and vice versa. If you want to isolate the namespaces of the two scripts, you can use procedures or namespaces to achieve that.
