For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
creating packages in Expect

Posted by expectnewbie (expectnewbie), 21 April 2005
Has anyone created packages in Expect?
pkg_mkIndex command seems to recognize only *.tcl files. It does not take in *.exp files.

I renamed my expect scripts without the exp extension, but the pkgIndex.tcl files is empty.

PLease help!

Thank you

Do remember that if you're using namespaces in the package, you need to export the procs that you want to be indexed.

I'll be doing some Expect tomorrow ... I'll have a look and see if I can put an example together ... but let me know if the above suggestion solves it first.

Here's an example that works for me ...

file rping.exp starts


package provide pulse 1.0

#%% Web based script - ping a series of remote hosts

proc lifecheck {args} {

log_user 0
set timeout 20
set runningcount 0
set hosts $args

foreach system $hosts {
       spawn ping -c 2 $system
       lappend idlist $spawn_id
       set realhost($spawn_id) $system
       incr runningcount

From the command line, I ran

pkg_mkIndex . rping.exp

and the pkgIndex.tcl file generated was

# Tcl package index file, version 1.1
# This file is generated by the "pkg_mkIndex" command
# and sourced either when an application starts up or
# by a "package unknown" script.  It invokes the
# "package ifneeded" command to set up package-related
# information so that packages will be loaded automatically
# in response to "package require" commands.  When this
# script is sourced, the variable $dir must contain the
# full path name of this file's directory.

package ifneeded pulse 1.0 [list source [file join $dir rping.exp]]
