[Xotcl] trace command

Hello Gustaf,

Is it possible to use the TCL trace on NX objects/methods?

Thanks

I'm actually working on a package built on top of normal [binary] which
would allow a clearer definition of the format of the binary data.
Something like:

byenary::scan $data {
     option endian little
     type cellObject {
         short objID
         int8 triByteNum

         int8 $triByteNum triVisibility
     }

     format {
         object root {
             short objNum
             short triNum

             cellObject $objNum objects
         }

         object * children {
             short objID
             short objNum
             short triNum

             cellObject $objNum objects
         }
     }
}

The aim is then that it returns a hierarchy of objects to represent the
data. I actually made a version already, but it parses that format
description manually and continuously. Even if I split the script into
lists, I still have to go through that. The format description is
intentionally made to look like a Tcl script with the idea that later I
could evaluate it in the appropriate context and let Tcl do the work (and
also byte compile it).

Now I'm thinking about doing that not by XOTcl mechanisms but namespaces.
Perhaps that could be the best option.

[Xotcl] how to track a segmentation fault problem in Xotcl?

Created by hypermail2xowiki importer, last modified by Stefan Sobernig 02 Jan 2017, at 11:15 PM

Hi,

I have just re-installed Xotcl 1.0.2 version and succedeed in running my
application with some minor changes since the last xotcl version I used on this
platform (Sparc/Solaris 7) was the 0.9 :-)

I have a segmentation fault that occurs when a command is called from a Tk menu.
The command is attached to the popup by a:
        add command -command
statement on a menu Tk widget that is raised by a tk_popup.

However, the very same command, when called from the tcl (xowish) interpreter, works
and does not produce any core dump. And most menu items also work well.

So my question is: how do I debug such a situation?
Thanks for any help...

Your explanation is certainly consistent with the behavior I observed. Is this documented somewhere?
It surprised me.

I don't know. What do you mean by "conditional mixin"?

[Xotcl] How to build XOTcl as universal binary

Is it possible to build XOTcl as universal/fat binary for OS X? What is
the command line for the configure tool ?

Thanks.

Actually no it won't, it's broke... needs " ; \ " at the line ends of the
new chmod lines. Here's a better patch (attached).

    [Xotcl] Windows Binary

    High,
    is there a reason why the Windows Binary is only xotcl-1.3.4, but Linux has
    xotcl-1.3.5 ?

    Re: [Xotcl] Xoctl lite tcl only version

    Created by hypermail2xowiki importer, last modified by Stefan Sobernig 02 Jan 2017, at 11:15 PM

    Hi,

    as far as I know, at the moment no such effort exists. In the very beginning
    of designing XOTcl, we had thought about it, but actually we came never back
    to this idea, though it is surely an interesting one. Our decision for the
    C-based solution was mainly based on efficiency considerations. However, now
    I'm pretty sure that a pure Tcl xotcl-lite would perform at a reasonable
    speed. Some things would be really tricky, but in a lite version most of them
    could be left out.

    So the tcl only version idea is around for quite some while. If a few people
    would like to help building such a lite version I would definitely
    contribute, but at the moment, I fear, I don't have the time to start-off
    developing it on my own ... the problem is that starting off with something
    could be done relatively quick, but getting it to an industrial level so that
    its accepted in tcllib would be much, much more work ...

    Uwe

    Well as long as the XOTcl library is available on the machine and for
    Apache then yes, you can use XOTcl along with Rivet. In fact, that is
    exactly what we're doing at the moment :-)
