general info about the configuration I use.

Directory structure for Pcb's

./gschem                       # circuit diagrams
./pcb                          # pcb files
./pcb/jhaand_nfcl              # exported gerber files, ready to send
./[proj]_fw                    # firmware
./parts/resources/             # dir structure per manufacturer and part
./parts                        # dir for all component info
./parts/resources/connectors   # generic connector shapes
./parts/resources/gschem       # generic gschem symbols
./parts/resources/KEMET_MLCC   # A cap from kemet
./parts/resources/NXP/BC847BS  # A dir containing all NXP parts
./parts/shape                  # PCB footprints from resource dir
./parts/sym                    # all used symbols from resource dir

A component database with all the known parts in them om a central place looks like a really good idea. At the moment I don't have enough content or structure to pull this off. Heavy components remain preferable. So the symbols have a specific type designation, footprint, manufacturer name, source and order code.

gschem needs to know where all the parts reside. Script for gafrc in the project directory. Needed for gschem.

(reset-component-library)
(component-library "./parts/sym/")
(log-window "later")

(define default-titleblock "title-bordered-A2.sym")
(output-color "enabled")
(image-color "enabled")
(undo-panzoom "disabled")

The “project” file for stringing it all together. resides in project directory.

schematics gschem/01-NFCL.sch
skip-m4
elements-dir parts/shape
output-name pcb/nfcl

Script to update all symbols; update_all_symbols

#!/bin/bash
touch iets.sym
rm *fp
find ../resources/ -name \*.sym -exec ln -s {} \; 

To regenerate the refdes numbers.

refdes_renum sch/*sch

How can i see which shapes I need?

grep -i footprint *sch |cut -f 2 -d= |sort |uniq

Script to update all shapes; update_all-shapes

#!/bin/bash
touch iets.fp
rm *fp
find ../resources/ -name \*.fp -exec ln -s {} \;
