[Kicad-developers] Request in s-expression format: general user data or comment
Hello everyone, I have a request for the s-expression format for footprints: a field for data that is not used by pcbnew or the module editor, but that is preserved (by the module editor). Something like (fp_userdata general text string). In the alternative, I would like to request to be able to put comments in an s-expression. Those comments need not be preserved (by the module editor). Rationale: I am developing a footprint wizard, based on templates. But a wizard won't be of much use if you cannot modify the footprints later. So, this wizard reads back footprints and allows you to adjust them. However, detecting which template was used (and with what settings) may not be deterministically feasible, given the number of options. So, the best option is to store that information in the generated footprint. Even if the user changes the footprint in the module editor, the wizard would still be able to get the correct template. In the alternative (store the information in a comment), the user would be able to adjust the footprint with the wizard, as long as no changes have been made to it in the module editor. This is good enough for me. Question: I do not appear to be able to select an s-expression library in pcbnew. Is this correct? Or do I need to build KiCad with a special option?

Re: [Kicad-developers] Request in s-expression format: general user data or comment
Hi Dick, Could you let me know your schedule on setting _pcbnew.so to be built all the time, instead of only with scripting, once it gets closer? That might be a good time for me to push out some of my Linux build changes. Thanks!

Yes, but I am not linking to the KiCad code.

OK. But I will focus on the footprint manager/wizard first. It is a long way
from
finished. When that is done, I will see whether I can patch the module editor.
Thanks for pointing me to DSNLEXER. It is a bit clearer now, how the
s-expressions are
parsed and formed. One question about the quotation marks, though: apparently
these can be
changed from a double quote to either a singe quote or a dollar sign.
No, not in non-specctrMode. non-specctraMode equals KiCad mode within
DSNLEXER.
See kicad_src/Documentation/s-expressions.txt
In KiCad mode (aka non-specctraMode), *only double quotes are to be used*.
Then when preparing a non-numeric string for output, we always call
OUTPUTFORMATTER::Quotes() or OUTPUTFORMATTER::Quotew(), unless it is a number,
in which
case you can be certain it will not need to be quoted. Quote{s,w} will not
quote unless
quoting is needed, and will also escape any interior double quote.
But how does that
work? Must the new quote character indeed be prefixed by ASCII code -9? If
so, is that the
same as ASCII 247?
1) Is your code GPLv2?
If yes, then you should be using PCBIO class (in kicad_plugin.{h,cpp} and
DSNLEXER and
OUTPUTFORMATTER at this point.
Otherwise your code is based on sand.
PCBIO may not be truly the opposite of sand, but as it moves you will move if
you are
based on it.
In fact I will not even answer any more questions which indicate that you are
not using
the foundational classes or APIs and trying to roll your own in C++.
2) madparts is ahead of KiCad itself regarding the *use of* the new pretty
format. I do
not know about your code, but spent some time looking at madparts. The guy
understands
the pretty format, how to store parts in a pretty directory, and fully
understands that
that is our future, not the legacy format. The moment the fp lib table is
done, anyone
can switch over immediately or continue to operating using a blend of legacy,
eagle,
pretty, or geda footprints, each in their own fp libraries.
I just *now* completed the ability to round trip leading (initial) comments in
the
standalone pretty modules/footprints. This does not apply to modules found in
boards,
only stand alone modules, such as *.kicad_mod files either as exports or in
pretty libraries.
For the madparts dude, he can probably put the entire coffee script in a
comment block at
the front end of the module if he wants. You can also now put your templating
information
there also. This was a planned feature from day one, actually not driven by
you, and this
is why I did it so fast. I meant to do it way back when.
Regards,
Dick

Is the printing situation for Linux using wxWidgets 2.9.4 any better? Anybody else have any better ideas or thoughts on this? I just made some trials with 2.9.4 and 2.9.5 (and cups): Nothing works either using the wxWidgets internal printing layer (dcpsg.cpp) or using wxWidgets built with --with-gtkprint option (--with-gnomeprint does not compile on my Linux install): --with-gtkprint gives not usable results (missing lines, incorrect arcs and much more...)

I wonder what the Gnome folks are doing because I haven't noticed any issues printing from some of the Gnome apps. Someone want to derive an object from wxPrintout that fixes the GTK printing issues? I stopped trying printing with wx based apps a lng time ago. That my experience with it. OTOH I'm using a 'traditional' printing system (no CUPS, only lprng and *real* postscript printers, so no rasterizers in between...) This is the best way. If no one minds, I think I'll move the warning from common.h to common.cpp rather than dsiplaying the warning for every source file that includes common.h (which is most of them) which is rather annoying. ___ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@lists.launchpad.net Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
[Kicad-developers] Auto-fill for zones
