data_desk VS kcgi

There are various ways you can do metaprogramming in C. Ryan Fleury's Data Desk is one example of how you can do inspection and introspection: https://github.com/ryanfleury/data_desk. Writing a C program that acts as a pre-compiler for your other C code is another example; you can make your own system for generics that way for example.

You can use KCGI to use C or C++ as a FastCGI backend.

I like the premise of embedded generating inline c. Kinda like php for c, rather than html

I'm not sure of custom BNF per generating command. I notice they're mostly order independent, which makes it a little easier to learn, but what's the advantage over c syntax? Is it roughly that pointers etc are impossible. Maybe a c-esque syntax would be more learnable

How does the existing syntax compose, i.e. can the user run away with writing tcl-style scripts

If you don't get a lot of feedback, I would guess it is inpart due to custom syntax being an entry barrier to understanding

I don't know, I think html is easy, so people want power with php. On the other hand c is powerful and hard, by the time I'm using that, does Vely's custom syntax give me more than a set of convenient c library calls... such as https://kristaps.bsd.lv/kcgi/

In any case, I like the apis, and I think the premise has legs

It's not that hard, I use kcgi.

The C library used (https://github.com/kristapsdz/kcgi) is portable and working on linux as well. Putting this behind nginx as fastcgi seems very well doable.
