roll: third_party/pigweed Reland "docs: Enable Doxylink"

This is a reland of commit ed98e925da046f4ecfe802e890efb0258253f256

https://pwrev.dev/299993 was reverted because the local macOS ARM docs
build was failing. As of https://pwrev.dev/309760 that tryjob coverage
gap is now filled. The root issue was the hardcoded tagfile path in
//docs/doxygen/Doxyfile that change #299993 introduced. This hardcoded
path is invalid on macOS ARM. The new OUTDIR feature introduced in
https://github.com/TendTo/rules_doxygen/pull/30 lets us configure this
path properly for all host OSes.

Pigweed Sample Project

This repository outlines the recommended way of using Pigweed in a new or existing project. Feel free to fork this repository, or read it as a reference.

For more information see the Pigweed Getting started guide.

Check back for more complex examples and features coming soon!

Getting started

Make sure you've set up Pigweed's prerequisites.

If you're on Windows, you can automate the initial setup by downloading the first-time setup script from cmd.exe:

curl https://pigweed.googlesource.com/pigweed/sample_project/+/main/tools/setup_windows_prerequisites.bat?format=TEXT > setup_pigweed_prerequisites.b64 && certutil -decode -f setup_pigweed_prerequisites.b64 setup_pigweed_prerequisites.bat && del setup_pigweed_prerequisites.b64

Then you can run the script with the following command in cmd.exe:

setup_pigweed_prerequisites.bat

Note: You may see a few UAC prompts as the script installs Git, Python, and enables developer mode.

Once that is done, you can clone this project with the following command:

git clone https://pigweed.googlesource.com/pigweed/sample_project

Environment setup

Pigweed uses a local development environment for most of its tools. This means tools are not installed to your machine, and are instead stored in a directory inside your project (Note: git ignores this directory). The tools are temporarily added to the PATH of the current shell session.

To make sure the latest tooling has been fetched and set up, run the bootstrap command for your operating system:

Windows

bootstrap.bat

Linux & Mac

source ./bootstrap.sh

After tooling updates, you might need to run bootstrap again to ensure the latest tools.

After the initial bootstrap, you can use use the activate scripts to configure the current shell for development without doing a full update.

Windows

activate.bat

Linux & Mac

source ./activate.sh

Building

All of these commands must be run from inside an activated developer environment. See Environment setup

One-shot build

To build the project, documentation, and tests, run the following command in an activated environment:

pw build

Automatically build on file save

Alternatively, if you'd like an automatic rebuild to trigger whenever you save changes to files, use pw watch:

pw watch

Typical workflow

When you pull latest repository changes, run bootstrap:

source ./bootstrap.sh

If you're just launching a new shell session, you can activate instead:

source ./activate.sh

and rebuild with:

pw build

More info and Examples

Extended documentation and examples are built along code changes. You can view them at out/gn/docs/gen/docs/html/index.html.
