Maintainer needed

I've not used bitbake in a long time and I do not expect this to change soon. I don't have an environment to test new PRs so this project is not really maintained any more. If anybody who uses bitbake regularly wants to take over, just ask!

bitbake.el - Bitbake integration with emacs

This package provides integration of the Yocto Bitbake tool with emacs. Its main features are:

  • interacting with the bitbake script so that you can run bitbake seamlessly from emacs. When editing a recipe, recompiling is just one M-x bitbake-recompile command away,

  • deploying recipes output directly to your target device over ssh for direct testing (if your image supports read-write mode),

  • generating wic images,

  • a global minor mode providing menu and shortcuts,

  • an mmm based mode to edit bitbake recipes.

Installing

This package is available on Melpa: MELPA

Usage

Calling bitbake from emacs

First you'll need to start bitbake as a server. Use M-x bitbake-start-server to do so. If you haven't setup the bitbake-poky-directory and bitbake-build-directory variables, emacs will prompt for your poky and build directory. You can permanently set them by running M-x customize-group bitbake.

Now that the server is started, you can execute tasks for the current recipe or any recipe by running M-x bitbake-task. There are shortcut for the most common task, see the BitBake menu in Bitbake minor mode.

Deploying recipes

If your target device supports ssh and writing to the root file system, you can use M-x bitbake-deploy to deploy a recipe on the device. It will use tar to create an archive of the files generated on the host and deploy them on the device. You should make sure that the recipe has already been build before or use the M-x bitbake-recompile-deploy command.

Generating wic images

If you use wic to create images, you can use M-x bitbake-wic-create to generate an image. It will prompt for the definition file the image name. You need to first build the Yocto image or use the command M-x bitbake-hdd-image which will first run bitbake image and then wic. If you set the custom variable bitbake-flash-device you'll be able rebuild and put your wic image directly on the device with the command M-x bitbake-flash-image.

Bitbake global minor mode

There is also a minor mode which provides shortcut and menu for those commands, run M-x bitbake-minor-mode and look at the BitBake menu for commands and key strokes.

Bitbake recipe mode

Finally, you should get syntax highlighting when editing bitbake recipe files. It uses mmm-mode to provide python and shell support in tasks.

Development

Development is done on GitHub. Any bugs or patches are welcome.
