which source file in rust language source refers_to/parse language keywords

Question

I want to change keyword spellings in Rust language. For example, for -> phur, so where should I look in rustc source code? Thanks in advance.

Answer 1

There isn't just the one place you'd need to change.

The keywords themselves are defined in src/librustc_span/symbol.rs but many things in the compiler internals rely on those keyword not to change, including:

• macro expansion
• Any kind of syntactic sugar relying on the quote! family of macros.
• pretty printing
• the test suite
