| Reduce Code Size for Mynewt Image |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| |
| **Q**: How do I reduce the code size for my Mynewt image? |
| |
| **A**: Please refer to the tutorial documentation on :doc:`reducing application code size <../../tutorials/other/codesize>`. |
| |
| ``compiler.yml`` vs. ``pkg.yml`` |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| |
| **Q**: What's the difference between ``compiler.yml`` and ``pkg.yml``? |
| |
| **A**: ``compiler.yml`` defines a compiler. ``pkg.yml`` contains metadata about the package. All packages have a |
| ``pkg.yml`` file, even compiler packages. |
| |
| Version Control Applications with Git |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| |
| **Q**: What's the recommended way to work with git when you want to version control your application? As ``apache-mynewt-core`` is already a repository, there is a repo in repo problem. Are there any good alternatives/tools to submodules, mirror, etc? Ideally, I want to version control everything from the top level project directory as well as upgrading apache-mynewt-core, pushing pull requests back to Mynewt if needed, etc. |
| |
| **A**: You can simply have a separate git for your app. For example, if you followed the Blinky tutorial, your git would be in ``apps/foo``, while repos gits are in repos. You may also keep your app in the core repo, just have your own working branch for it. |
| |
| Another option is to have your git repository with local packages (including apps) and have ``repository.yml`` there so ``newt install`` can download all dependencies. Just make sure to put e.g. ``bin``, ``repos``, and ``project.state``, and others in ``.gitignore`` so they are not in version control. |
