CLI - how to integrate codegen properly?

https://docs.rs/syn/0.14.7/syn/#optional-features

Edit: To make the issue less confusing, the problem is that we use types from the proc_macro2 crate (TokenStream...) to do codegen, and that can't be linked statically. So codegen from the CLI may be tricky.

Not exactly sure what you're planning here, but just as an FYI: in my understanding you're not allowed to link to proc_macro from a binary running outside of the Rust compiler. See djc/askama#73 and the linked issues for more information.

It was just a note because I remember having trouble in another project that did code generation using the proc macro infrastructure (syn, quote, etc.). I will put a disclaimer on the CLI README because it's not the highest priority feature at the moment (apollo-cli works just fine as a replacement).
