choc footprint produces kicad pcb file error

[mlilley]

Choc footprint seems to have broken sometime in the last few weeks. This:

      switches:
        what: switch_choc_v1_v2
        where: true
        params:
          choc_v2_support: false
          from: "{{column_net}}"
          to: "{{colrow}}"
        adjust:
          rotate: 180

produces a pcb file that kicad can't load:

Expecting 'end' in '/Users/aaaa/bbbb/cccc/dddd.kicad_pcb', line 272, offset 32.

the footprint at that location looks like (I've marked line 272 with a comment):

If I minimally change to the ergogen included choc footprint with the following, the pcb file can be read fine.

      switches:
        what: choc
        where: true
        params:
          from: "{{column_net}}"
          to: "{{colrow}}"
        adjust:
          rotate: 180

Ergogen 4.0.5, Kicad 8.0.1

[ceoloide]

The error you quote is shown by KiCad when you open a KiCad 5 *.kicad_pcb file containing KiCad 8 footprints that have incompatible syntax (like fp_arc which changed syntax from KiCad 5 to 8).

I updated the README.md to explicitly call out how to force a KiCad 8 file, but in short:

• Make sure you have ergogen v4.1.0 or greater
• Have template: kicad8 in your pcb definition (see README.md for an example)
• Use KiCad 8 or greater to open the file

I won't be supporting KiCad 5 moving forward, but should you need KiCad 5 compatible footprints, there is a version and branch tagged specifically with that.
