That's not an alternative way, that's literally what the post is critiquing. There's nothing stupid about configuration files, on the contrary, it's completely nonsensical and conceptually wrong to have enduser runtime configuration written into compile time source code. It also entirely defeats the ostensible purpose of making "non-bloated" software because it doesn't get much more bloated than having to recompile an entire program every time you want to make a trivial change that could just be read from a file. You've now made having the entire compiler toolchain installed a requirement if someone wants to change a font. It's the equivalent of burning your house down and building a new one because you want to change a poster on the wall. Suckless software is just an exercise in contrarianism.
