# Unstable kconfig module
|
|
|
|
|
|
|
|
|
|
|
|
This module parses Kconfig output files to allow use of kconfig
|
|
|
|
|
|
configurations in meson projects.
|
|
|
|
|
|
|
|
|
|
|
|
**Note**: this does not provide kconfig frontend tooling to generate a
|
|
|
|
|
|
configuration. You still need something such as kconfig frontends (see
|
|
|
|
|
|
link below) to parse your Kconfig files, and then (after you've
|
|
|
|
|
|
choosen the configuration options), output a ".config" file.

## Usage
|
|
|
|
|
|
|
|
|
|
|
|
The module may be imported as follows:
|
|
|
|
|
|
|
|
|
|
|
|
``` meson
|
|
|
|
|
|
kconfig = import('unstable-kconfig')
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
The following functions will then be available as methods on the object
|
|
|
|
|
|
with the name `kconfig`. You can, of course, replace the name
|
|
|
|
|
|
`kconfig` with anything else.
|
|
|
|
|
|
|
|
|
|
|
|
### kconfig.load()
|
|
|
|
|
|
|
|
|
|
|
|
This function loads a kconfig output file and returns a dictionary object.
|
|
|
|
|
|
|
|
|
|
|
|
`kconfig.load()` makes no attempt at parsing the values in the
|
|
|
|
|
|
file. Therefore, true boolean values will be represented as the string "y"
|
|
|
|
|
|
and integer values will have to be converted with `.to_int()`.
|
|
|
|
|
|
|
|
|
|
|
|
Kconfig frontends usually have ".config" as the default name for the
|
|
|
|
|
|
configuration file. However, placing the configuration file in the source
|
|
|
|
|
|
directory limits the user to one configuration per source directory.
|
|
|
|
|
|
In order to allow separate configurations for each build directory, as is
|
|
|
|
|
|
the Meson standard, `meson.build` should not hardcode ".config" as the
|
|
|
|
|
|
argument to `kconfig.load()`, and should instead make the argument to
|
|
|
|
|
|
`kconfig.load()` a [project build option](Build-options.md).
|
|
|
|
|
|
|
|
|
|
|
|
* The first (and only) argument is the path to the configuration file to
|
|
|
|
|
|
load (usually ".config").
|
|
|
|
|
|
|
|
|
|
|
|
**Returns**: a [dictionary object](Reference-manual.md#dictionary-object).
