Simon Ser a4d2bbf95f build: set symbol visibility 
A simple version script is used because it allows us to consistently
expose all symbols starting with "di_", removing the risk to forget
to mark a symbol as public.

README.md

libdisplay-info

EDID and DisplayID library.

Goals:

  • Provide a set of high-level, easy-to-use, opinionated functions as well as low-level functions to access detailed information.
  • Simplicity and correctness over performance and resource usage.
  • Well-tested and fuzzed.

Contributing

Open issues and merge requests on the GitLab project.

In general, the Wayland contribution guidelines should be followed. In particular, each commit must carry a Signed-off-by tag to denote that the submitter adheres to the Developer Certificate of Origin 1.1. This project follows the freedesktop.org Contributor Covenant.

Building

libdisplay-info is built using Meson. It has no dependencies.

meson build/
ninja -C build/

Testing

The low-level EDID library is tested against edid-decode. test/data/ contains a small collection of EDID blobs and diffs between upstream edid-decode and our di-edid-decode clone. Our CI ensures the diffs are up-to-date. A patch should never make the diffs grow larger. To add a new EDID blob or update a diff, use test/edid-decode-diff.sh test/data/<edid>.

Fuzzing

To fuzz libdisplay-info with AFL, the library needs to be instrumented:

CC=afl-gcc meson build/
ninja -C build/
afl-fuzz -i test/data/ -o afl/ build/di-edid-decode
