gEDA-user: [pcb/lesstif] allow zoom out and pan more than board size
Attention pcb-lesstif users: here's a patch that lets you zoom out
more than the pcb size! Also lets you pan the board anywhere, not
just to the edge of the window (i.e. you can position the edge of the
board in the middle of the window now). The 'v' key still zooms to
"view all" and ctrl-middle-button is a bit more sane
(i.e. ctrl-middle-click on the lower right corner of the window,
centers the lower right corner of the PCB in the window). No core
changes, so you still can't move stuff (or even the crosshair) off the
board.
If this seems to work, I'll push it out.

No. The slotting semantics are hard-wired into the gEDA core code. I doubt that most of the current core developers even realize that these semantics need to depend on the kind of netlist to be generated. One now inactive developer (Stuart Brorson) tried to create common semantics for printed circuits and simulation, but his attempt just broke slotting for all purposes. For now, in most cases it is impractical in gEDA to try to directly simulate a schematic that's intended for printed circuit layout. This is not a unique problem to gEDA: I've had the same difficulty with a big $$ commercial EDA toolkit. I have some plans in this area, but don't hold your breath.

gEDA-user: Spice output with slotted symbols
My spice output is looking a little iffy on the symbols I have created which are slotted. In particular I have a Power part and an op amp part to one of my symbols. The Op amp can occur in 1 of 2 slots. Each instance of the symbol appears to be creating a distinct line in the spice output. XU1.1 BACKUP_OUT BACKUP_OUT BACKUP/S unknown XU1 0 1 unknown For example in the above line, I see two entries for the op amp XU1. Neither entry is correct as the op amp subcircuit model expects 5 parameters. Is there a way of getting gnetlist to interpret these symbols correctly?

You know those boxes with characters in them, for example a square box with an & sign in it for an AND gate. I looked at the gEDA symbols site, but it was very hard to find anything useful in this matter, since there was no ”preview” thing involved as far as I can see.

Libgpmi doesn't have much documentation, true. I've just found I even broke the website. Will fix it soon. Meanwhile, list of languages supported: - awk (using libmawk) - lua - scheme (guile) - stutter (a lisp dialect) - pascal (ghli - may be broken at the moment) - perl - php - python - ruby - tcl - of course you can write your module in C and load it as a shared object You can find a more detailed list at http://repo.hu/projects/pcb-gpmi/languages.txt > Is there any plans or needs for a scripting language (like guile/perl/ > ...) for pcb? On the above list you can find both of those languages. Anyway you won't find references of this in pcb sources. The whole thing is a plugin and a set of gpmi packages. The design is like this: [PCB] -> [pcb-gpmi plugin] -> [scripts] -> [interface packages] ^ | | | +--+ Or in text: PCB loads a plugin called pcb-gpmi, which will load a config file and according to that, will load a set of scripts. Scripts will in turn load interface packages. Interface packages are tiny shared object files which provide an interface between PCB internals and scripting languages. The idea is to have some sort of higher level API which does not change much and is more convenient. How powerful the whole thing can get depends on how many languages it supports and how much of the PCB internals are exposed. I believe the list of languages is impressive. Unfortunately interface packages are only a few, and thin, only as much as I needed for proof-of-concept or to fulfill my daily needs on missing PCB features. Here is a short list of already working packages: - actions: scripts can create actions usign this package. - dialogs: create dialog boxes using the current hid; your script can pop up data entry windows, give warnings, etc. - hid: allows the script to regiester an exporter hid with dynamic attributes - layout: query or draw objects on the current layout There are a set of example scripts written in different languages to demonstrate ease of use of PCB internals with pcb-gpmi: - carc: custom angle arc support written in lua; registers an action that pops up a dialog where user can set angles and other properties of an arc that will be then placed on the layout using the current layer/style. - SVG exporter written in tcl; proof-of-concept but already can export a somewhat good looking SVG. - HPGL exporter written in awk; cares only about lines but can repeat lines by layer. I own an old pen plotter I drive with this hid. You can find the scripts at http://repo.hu/projects/pcb-gpmi/plugins/ pcb-gpmi is documented; you can read the on-line documentation at http://repo.hu/projects/pcb-gpmi/doc/ ; gpmi, as you mentioned, is largely undocumented. However, if you are interested in using pcb-gpmi for scripting your plugins, you don't need to know anything about gpmi, the same way as using PCB GTK hid for drawing your layouts doesn't imply you need to know how GTK works. Of course this is no good excuse for missing doc, I just wanted to point out that missing documentation of gpmi is not a show stopper. On the other hand, since user count of the project is exaclty 1 (that is me) for the past ~4 years, don't expect it to be user-friendly. For example current svn HEAD of gpmi probably won't work out-of-the-box with pcb-gpmi, and you will need to use the last release instead. If I had users I would have made a branch for the big cleanup I am doing on gpmi lately, but as I didn't have users I just started it on trunk. If you are still interested in the project, I can support compiling and installing.

Is there a way to see this in PCB? >Oliver Place footprint, then: - hover mouse cursor over the component (not over pin), press d: all pin numebrs will appear - hover over a pin, press d: pin number of the given pin appears - hover over a pin or component and press shift+d: pin number dialog opens The above work with the gtk hid, I don't know if bindings are the same for the lesstif hid. Recent versions of PCB with gtk hid also displays pin numbers in the preview window while selecting footprints. hope this helps, Tibor Palinkas ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
