Instructions for running the utilities

c_toolchain utility docker image

This is the consistent C toolchain environment, containing all the tools needed to run and develop the project.

Dockerfile: dockerfile.c_toolchain Run the docker-compose command to get a bash shell that is bound to the dmzOS directory:

docker-compose run --rm c_toolchain

Any changes in the container dmzOS directory will be reflected in the local dmzOS directory.

The image contains indent and clang-format as C code formatters.

A .vimrc file is automatically part of the image, and it contains a rule to make vim run the following formatting command on buffer save:

indent -kr -ts4 %

This is using the Kernighan and Ritchie code styling, as well as identations with 4 spaces.

If you want to use your own .vimrc, please replace the existing .vimrc file inside the config directory with it.
