installed packages in Tcl

[shady.ab...@gmail.com]

Hi All,

I would like to know which extensions do i have installed for the tcl
interpreter I have. what command to type or what correct path to look
in.

thanks in advance.

[Aric Bills]

Type "package names".

[shady.ab...@gmail.com]

thank you Aric,
it worked fine. But how about the paths of those extensions? I can't
find them in the lib directory.

The $auto_path variable contains the list of directories whose
subdirectories Tcl searches for packages.

I tried: echo $auto_path, but i received the following message:
auto_path: Undefined variable.

any help?

[Aric Bills]

$auto_path is a tcl variable, not an environment variable. Fire up
tclsh and type in "puts $auto_path" to see its value.

You have to do it from the TCL shell:
puts $auto_path

More deeply, you can do:
package ifneeded packageName [package require packageName]

This will tell you exactly how and from where to install
a given package. Usually this is straight-forward but some
packages install in bizarre ways.

I tried "package ifneeded packageName [package require packageName]",
but i received an error from the package require because it can't find
the packageName.

To be more precise, I tried including the "struct" package and the
"math::interpolate" package, but I don't know from where to download
them!!

There are pitfalls:

can't find package foobar

yes... i realized this also, but i don't know why it happens???

[shady.ab...@gmail.com]

the wiki and sourceforge do not have all the packages... any
suggestions from where to get them? and also how to know that i have
the dependencies for the downloaded packages??

thanks

tcllib provides a wide range of (sub) packages
and you will only realy need the extra functionality
you have decided on to use.

aggregated package information:
http://www.tcl.tk/software/
http://www.flightlab.com/~joe/gutter/browse.html

upwards:
you have to require the package version that has
the features you need ( if they have been added in
a later version )
downwards:
during load packages are supposed to check if the
tcl/tk version and other required packages present
are "good enough".

Type the following:

can't find package NotThere
% lsort [package names]

chatwidget cksum cmdline comm control counter crc16 crc32 csv ctext
cursor datefield des

and so forth.

What you see will be dependant on what you have installed.

You might take a look into TkMan . I've used it on Unix systems in the
past to browse installed documentation. Unfortunately, there may be
cases where you don't have the man pages for the extensions you have
on your system.

Three cases where this can come up - 1) tclkit type interpreters, 2)
ActiveTcl with extra packages installed via teacup, 3) extensions
which only provide their docs in some form other than man pages.

In these cases, if you have access to the internet, web search engines
as well as http://wiki.tcl.tk/ can frequently help. If you do not have
access to the internet, then help figuring out how to use the package
may be a bit challenging.

[Larry W. Virden]

Right now, the best help for you along these lines is ActiveTcl and
its "teacup" command. It interacts with a central database containing
many (on some platforms, over 400) extensions. Interacting with teacup
gives you the potential to install extensions already built.

If you read up on teacup, you will find there is also the ability to
have teacup "describe" an extension, and often the information about
dependencies and web home are stored in the metadata for the
extension.

If you can't find the information on the wiki, or via teacup, then ask
for specifics here and often people will be able to help.
