jc - JSON Convert pci.ids file parser

This parser converts the pci.ids database file.

https://raw.githubusercontent.com/pciutils/pciids/master/pci.ids

A nested schema allows straightforward queries with tools like jq. Hex id numbers are prefixed with an underscore (_) so bracket notation is not necessary when referencing. For example:

$ cat pci.ids | jc --pci-ids | jq '.vendors._9005._0053._9005._ffff.subsystem_name'
"AIC-7896 SCSI Controller mainboard implementation"

Here are the vendor and class mappings:

jq '.vendors._001c._0001._001c._0005.subsystem_name'
              |     |     |     |
              |     |     |     subdevice
              |     |     subvendor
              |     device
              vendor

jq '.classes._0c._03._40'
              |   |   |
              |   |   prog_if
              |   subclass
              class

Usage (cli):

$ cat pci.ids | jc --pci-ids

Usage (module):

import jc
result = jc.parse('pci_ids', pci_ids_file_output)

Schema:

{
  "vendors": {
    "_<vendor_id>": {
      "vendor_name":                 string,
      "_<device_id>": {
        "device_name":               string,
        "_<subvendor_id>": {
          "_<subdevice_id":          string
        }
      }
    }
  },
  "classes": {
    "_<class_id>": {
      "class_name":                  string,
      "_<subclass_id>": {
        "subclass_name":             string,
        "_<prog_if>":                string
      }
    }
  }
}

Examples:

$ cat pci.ids | jc --pci-ids | jq '.vendors._001c._0001._001c._0005.subsystem_name'
"2 Channel CAN Bus SJC1000 (Optically Isolated)"

$ cat pci.ids | jc --pci-ids | jq '.classes._0c._03._40'
"USB4 Host Interface"
