Modules in Tcl

There are more ways ...

• source a Tcl file
• Tcl modules (*.tm files)
• Packages <https://wiki.tcl-lang.org/page/Tcl+Package+Developer+Guide>

Tcl Modules

Directory structure:

<path>
  +- foo.tcl
  +- [mods]
        +- bar-1.0.tm

Use:

$bash> export TCL8_6_TM_PATH=${pwd)/mods
$bash> tclsh foo.tcl
Foo started ...
Bar Me...
Foo completed, cao!

Here is how the .tm module may look like:

namespace eval ::bar {
}

proc ::bar::barMe {} {
    puts "Bar Me...";
}

And the Tcl script:

package require bar;

puts "Foo started ...";
::bar::barMe;
puts "Foo completed, cao!";
