Usage

Python 3 script

DmiParser

This accepts a str (with the output of dmidecode) as argument and converts it to JSON text.

#!/usr/bin/env python3
import json
from dmiparser import DmiParser
from functools import partial


def report(*args: str) -> None:
    """report texts with format

    @param args: text string
    """
    br = lambda e: print("-" * e)
    brn = partial(br, 80)

    brn()

    for e in args:
        print(e)
        brn()


if "__main__" == __name__:
    text = (
        "# dmidecode 3.0\n"
        "Getting SMBIOS data from sysfs.\n"
        "SMBIOS 2.7 present.\n"
        "\n"
        "Handle 0x0003, DMI type 2, 17 bytes\n"
        "Base Board Information\n"
        "\tManufacturer: Intel Corporation\n"

        "\n"
    )

    # parser = DmiParser(text)
    parser = DmiParser(text, sort_keys=True, indent=2)

    parsedStr = str(parser)  # get str
    parsedObj = json.loads(str(parser))  # get object

    report(parsedStr, parsedObj)

DmiDecoder (the default wrapper)

This run dmidecode and converting the output of the command to JSON text.

from dmiparser.dmidecoder import DmiDecoder
from functools import partial


def report(*args: str) -> None:
    """report texts with format

    @param args: text string
    """
    br = lambda e: print("-" * e)
    brn = partial(br, 80)

    brn()

    for e in args:
        print(e)
        brn()


def getCpuInfo(dmidecoder) -> str:

    report(dmidecoder4.text, str(dmidecoder4.data), getCpuInfo(dmidecoder4))

Tip: Superuser permissions are required here to run dmidecode.

Executable command

dmiparser

This read output of dmidecode from pipe and print it as JSON text.

sudo dmidecode | dmiparser
sudo dmidecode -t 4 | dmiparser --format

sudo dmidecode >/tmp/dmidecode.txt
dmiparser </tmp/dmidecode.txt

Tip: you can run dmiparser module as a script (use python3 -m dmiparser instead of dmiparser command).

dmidecoder

This run dmidecode and print the output as JSON text.

sudo dmidecoder
sudo dmidecoder --arguments "-t 4" --format

Tip: you can run dmiparser.dmidecoder module as a script (use python3 -m dmiparser.dmidecoder instead of dmidecoder command).
