Yeah the cross-compilation thing is definitely a rough spot. I have one project that's able to work around it via extensive hacks with macros, but at some point I'll need to do it "the right way."

Honestly if the docs had a canonical example of e.g. using unix_cc_toolchain_config (example: [0]) + Bootlin to compile for aarch64, it'd probably go a long way to making things understandable. Because say what you will about the old CROSSTOOL approach, at least there was a nice tutorial for it.

I'm really not familiar with this issue or Go nor C++ overall, but if all you need is to set up a C++ toolchain, this should be quite simple and solve your issue.

The trick is that to provide Bazel with a custom toolchain involves way more than just setting an environment variable, because Bazel wants to control installing and making available the compiler reliably (e.g., what if `emcc` is not present on the system where Bazel was invoked? Bazel solves that problem by fetching it and building it for that system)

There are projects that provide drop-in support for custom toolchains (e.g., we use this project[0] in Sorbet to fetch and build a custom LLVM/Clang toolchain for every host we build on (rather than relying on the system toolchain). But I'm not aware of a project that has done that for Emscripten. Maybe it would be as easy as plucking out what we've done in our project into a project that others could depend on, but to quote a colleague:

> Setting up a cc toolchain in Bazel is a unique sort of pain.

This blog is running on Hugo. It had previously been running on Jekyll. Both these SSGs ship with the ability to create excerpts from your markdown content in 1 line or thereabouts.

Jekyll

In future, if you want to move from Jekyll to something else, you just have to worry about that `_posts` and `_assets` folder. They may have different naming convention but you can just config-managed it or change it to your choice. This is why I suggested owning that two yourself.

You also may not worry about FrontMatter[3] (meta in the header) and its accompanying jazz by asking Jekyll to use the plugins `jekyll-optional-front-matter` and `jekyll-titles-from-headings`. These comes as part of the officially supported Jekyll plugins[4] by Github. That way, you are just writing a human-readable plain-text spiced up with Markdown and readable by almost every other Static Site Generator.

Now, play with the `_config.yml` that Jekyll generates for you from the theme above to define your post dates, navigation, and others. Jekyll is one of the OGs — the Gandalf of Static Site Generators. If you have a problem, someone somewhere has solved that.

Did I missed something? I was supposed to write a blog article for my website on this one and this comment will serve as my starting bullet points.

"Using the Chirpy theme for Jekyll."

I would suggest looking into static site generators. Some popular examples, which are used myself are: - Hugo: https://gohugo.io/ - Jekyll: https://jekyllrb.com

In terms of GitHub stars, SSGs like Next.js, Hugo, Gatsby, Docusaurus, Nuxt.js, and Jekyll top the list. Some popular SSGs even host conferences and workshops, providing resources and networking opportunities for those looking to explore more advanced topics in depth.

I created my blog using Jekyll, a great open-source tool that can transform your markdown content into a simple, old-fashioned-but-trendy, static site. What are the advantages of this approach? The site is super-light, super-fast, super-secure and SEO-friendly. Of course, it’s not always the best solution, but for some use cases, like a simple personal blog, it’s really a good option.

Yes, it's Markdown and I use https://jekyllrb.com with the theme "jekyll-theme-hacker" to generate the site. I quite like how simple it is.
