raw string literals in sexprs? #39

Closed chetmurthy closed 5 years ago

chetmurthy commented 5 years ago

It seems like it might be nice for sexplib to support parsing sexprs containing raw string literals, just as ocaml now supports that. Would this be something you'd accept as a change in the syntax? I figure I should check before I go do the hack (which is arguably pretty minuscule).

I'm afraid that extending the syntax is not something we should do lightly. At least at Jane Street we have been using s-expressions for a long time and introducing a new extended syntax would inevitably cause some churn.

chetmurthy commented 5 years ago

Fair enough, I guess. I'll just make one other attempt, and then drop it.

I'm not suggesting -printing- s-exps with raw-string-literals; rather, only -parsing- them. This would be a new syntax for s-exps, so any existing s-exps that already parse, would continue to parse the same as before.

But sure, I can imagine that with a large enough codebase, it can become dangerous to make any changes other than those that seem truly necessary.

Oh, I see you have another layer of s-expression parsing in janestreet/parsexp. Hm, I think I can see why you want to leave that undisturbed. Closing.
