+[[https://ziglang.org/][Zig]] is to C kind of what Rust is to C++: a modern replacement without
+sacrificing performance. It is much safer than C while providing
+interop with it. Plus, its [[https://ziglang.org/documentation/master/std/][standard library]] is pretty complete.
+
+First, here is its major mode.

+  :after flycheck
+  :hook (zig-mode . lsp-deferred)

+  (flycheck-define-checker zig
+    "A zig syntax checker using the zig-fmt interpreter."
+    :command ("zig" "fmt" (eval (buffer-file-name)))
+    :error-patterns
+    ((error line-start (file-name) ":" line ":" column ": error: " (mesage) line-end))

+For LSP to work, we need ~zls~ to be installed.
