是否没有一个程序/库来解析常见的 unix 实用程序基于文本的输出，例如 lshw、iwlist、dmidecode？

我有一个 .net core 应用程序，它使用多个 UNIX 实用程序来查询硬件数据，例如lshw、iwlist、dmidecode。 lshw支持json输出，所以这不是问题。我目前正在编写自己的解析代码，令我惊讶的是没有工具可以解析此类工具的输出。

我是对的吗？

TXR是一种从结构松散的多行文本中提取信息的语言。

我们以 的输出dmidecode为例，将其转换为 JSON 对象列表：

$ txr dmi-data.txr  dmi-data
{"Version":"VirtualBox","Address":"0xE0000","Characteristics":["ISA is supported","PCI is supported","Boot from CD is supported",
                                                               "Selectable boot is supported","8042 keyboard services are supported (int 9h)",
                                                               "CGA/mono video services are supported (int 10h)","ACPI is supported"],

{"desc":"OEM-specific Type","Header and Data":["80 08 08 00 2B C3 33 00"]}

该程序如下所示：

# dmidecode @nil
@(skip)
Table at @nil

@(collect :vars (obj))
Handle @nil
@desc
@  (require (not (mequal desc "Inactive" "End Of Table")))
@  (bind obj @(hash))
@  (repeat :gap 0)
@    (cases)
@\t@prop: @value
@      (do (set [obj prop] value))
@    (or)
@\t@prop:
@      (collect :gap 0)
@\t@\t@valueline
@      (end)
@      (do (set [obj prop] (vec-list valueline)))
@    (end)
@  (until)
Handle @nil
@  (end)
@  (do (set [obj "desc"] desc))
@(end)
@(do (put-jsons obj))

该dmi-data文件包含：
