This is a command line interface to enhance buildroot for complex recipes.

It combines the BR_EXTERNAL approach, which is an upper layer of buildroot and a wrapper to operate `buildroot.

With the br-external feature, we can enhance buildroot with custom packages that are not officially supported.

With the provided cooker wrapper, we operate a buildroot according to a recipe descriptor to build an image on several architectures.
By default, buildroot approach is one Buildroot per Architecture.
With this wrapper we can build one buildroot for multiple architectures.

Set up environment

╰─$ source sourceme.sh 

cooker is the command line tool

List all recipes

╰─$ cooker --list

List known architectures

╰─$ cooker --list-boards

Cook a recipe:

╰─$ cooker --recipe my-recipe

Cook several recipes at once:

╰─$ cooker --recipe recipe1 --recipe recipe2 

All requirements are downloaded and managed in arbitrary ~/br2-downloads folder.
Use the dl-dir option if you want to use a different location :

╰─$ cooker --dl-dir /tmp --recipe recipe1 

Maintaining dl-dir folder accross cooking sessions, allows faster cooking processes.

All temporary and build results are created where cooker is summoned but you can change that behavior with the work-dir option:

╰─$ cooker --work-dir /tmp --dl-dir /tmp --recipe recipe1 

Print buildroot revision to be used :

╰─$ cooker --br2-revision

• Test a newer buildroot revision with

╰─$ cooker --br2-tag 2020.01.1 --recipe my-recipe

• use specific buildroot tree

╰─$ cooker --br2-url https://custom-buildroot.git --recie my-recipe
