both nd and ngui now acquire semantic versioning recorded at the build
time. they also report the version at startup and -v flag.
this is useful for a release process and to avoid potential
compatibility issues in the future.
in a regular build flow, the version is taken from a git tag using the
following command:
git -C . describe --match 'v*.*.*' --tags
in a non-standard scenario where git isn't available, the version can
be provided on the command line during build like so:
zig build -Dversion=1.2.3
if both git and command line supplied versions are available, they must
match.

README.md
nakamochi daemon and gui (ndg)
build for rpi:
zig build -Dtarget=aarch64-linux-musl -Ddriver=fbev -Drelease-safe -Dstrip
otherwise just zig build on dev host
local development
you'll need zig v0.10.x. if working on the gui, also SDL2.
note that compiling the daemon on macOS is currently unsupported since it requires some linux primitives.
compiling is expected to be as easy as
# only gui
zig build ngui
# only daemon
zig build nd
# everything at once
zig build
the output is placed in ./zig-out/bin directory. for example, to run the gui,
simply execute ./zig-out/bin/ngui.
the build script has a few project-specific options. list them all with
a zig build --help command. for instance, to reduce LVGL logging verbosity in
debug build mode, one can set this extra build flag:
zig build ngui -Dlvgl_loglevel=warn
run all tests with
zig build test
or a filtered subset using test-filter:
zig build test -Dtest-filter=xxx
significant contributors may find adding .git-blame-ignore-revs
file to their git config useful, to skip very likely irrelevant commits
when browsing git blame:
git config blame.ignoreRevsFile .git-blame-ignore-revs
see also the contributing section.
CI automated checks
the CI runs code format checks, tests and builds for fbdev+evdev on aarch64 and SDL2. it requires a container image with zig and clang tools such as clang-format.
to make a new image and switch the CI to use it, first modify the ci-containerfile and produce the image locally:
podman build --rm -t ndg-ci -f ./tools/ci-containerfile \
--build-arg ZIGURL=https://ziglang.org/download/0.10.1/zig-linux-x86_64-0.10.1.tar.xz
then tag it with the target URL, for example:
podman tag localhost/ndg-ci git.qcode.ch/nakamochi/ci-zig0.10.1:v1
generate an access token, login to the container registry and push the image to remote:
podman login git.qcode.ch
podman push git.qcode.ch/nakamochi/ci-zig0.10.1:v1
the image will be available at https://git.qcode.ch/nakamochi/-/packages/
finally, delete the access token from https://git.qcode.ch/user/settings/applications
what's left is to update the CI build pipeline and delete the older version of the image.
contributing
to contribute, create a pull request or send a patch with git send-mail to alex-dot-cloudware.io.
before sending a change, please make sure tests pass:
zig build test
and all code is formatted: zig code with zig fmt and C according to the
style described by .clang-format file. if clang-format tool
is installed, all formatting can be checked with:
./tools/fmt-check.sh
note that only C files in src/ are formatted.
leave third party libraries as is - it is easier to update and upgrade when
the original style is preserved, even if it doesn't match this project.
