You don't have to run Rockhopper all the time (which is the source of my problem). You can just launch it from the command line and connect to it with a web browser when you want to do a hal graph. If you launch Rockhopper after Linuxcnc is running you will never see the error I have. Rockhopper is completely independent of Linuxcnc so run it, do your hal graph, and then exit it.
The graphical layout of hal is great for designing, or debugging a configuration as you can easily trace all the logic. Very complicated hal configurations will not work so well as the graphviz algorithm that does the layout will begin to merge lines when a node has many inputs coming to it. We would like to add a better graphing algorithm at some point but we could only find expensive commercial ones with distribution issues. A schematic algorithm, like Ed is using in Eagle, would do a better job of not running lines on top of each other, etc. -Tom On Jun 18, 2013, at 3:41 AM, alex chiosso <achio...@gmail.com> wrote: > Hi people. > Reading this mail I discovered "Rockhopper python interface" feature that > honestly I have never heard before. > First of all it seems to be very useful. > It shows the hal file component connections graphically. > Is this feature available independently from "Rockhopper python interface" ? > I mean is there any way/procedure to show the hal files in a graphical way > without install the full "Rockhopper python interface" ? > Is there any way to design a hal file graphically ? > > Regards > > Alex > > > On Mon, Jun 17, 2013 at 8:05 PM, Tom Easterday <tom-...@bgp.nu> wrote: > >> So, it turns out this isn't a disk problem at all but a problem in our >> Rockhopper python interface that I have running by default on these >> machines.
