Features

Below examples are assuming you are running the tool globally

Note - uvx does sandboxing (virtualenv) for you so no need to worry

Get info on a KConfig item

# get the description as JSON output for CONFIG_LWM2M_SHELL
uvx zepyhr-kconfig --release 4.3.0 get CONFIG_LWM2M_SHELL

A partial CONFIG spec will get all items that start with the provided input for example CONFIG_LWM2M_ will output all L2M2M config items

Use --exact to get the info on CONFIG_LWM2M only

Use --metadata to get some extra fields (such as linenr, menupath etc)

Use --indent -1 to remove any indentation (default is 2)

Get deps on a KConfig item

# get the dependencies for CONFIG_LWM2M_SHELL
uvx zepyhr-kconfig --release 4.3.0 deps CONFIG_LWM2M_SHELL

For above example output would be:

CONFIG_LWM2M && CONFIG_NETWORKING

The input symbol should be exact

Pretty Print KConfig item(s)

# show the description of symbol(s)
uvx zepyhr-kconfig --release 4.3.0 pprint CONFIG_LWM2M_SHELL

Use --exact to print only one symbol
