I’m looking to render a bunch of Rust code out from a Racket program, is there a text templating tool that works well for this?

So your Racket program emits Rust?

yes, it will

in the past, I’ve used Antlr + Stringtemplate

(for JVM languages)

In the past I have had success with emitting in two stages. First make a tree of strings, symbols (and possibly numbers). Second emit all the leaves of the tree to the output port.

The idea is that , say, (list line1 line2 ...) is cheaper than (string-append line1 line2).

There are a few template related packages: https://docs.racket-lang.org/dali/index.html

thank you!

I suspected that I might not need a templating tool in Racket

but I suppose I’ll find out when I get there

FWIW here is an emitter I wrote to emit JavaScript. https://github.com/soegaard/urlang/blob/master/urlang/main.rkt#L2342

oh, excellent

I’ll dig into that

Change the link to the correct line.

Sometimes the #lang at-exp is useful for that sort of thing too. If there are long stretches of text.

interested, haven’t seen that before
