Potential issue with string example

[max-sixty]

Currently the literals section of the book gives this as a string example:

string = { "\"" ~ (raw_string | escape)* ~ "\"" }

Is my understanding correct that this will parse " USA" as USA, discarding the initial , because the rule isn't atomic?

I'm having this issue myself. I'm getting around it by making the rule atomic, but it seems rules can't be atomic & silent, and so the parse tree contains the "s, which requires a bit more work downstream.

Thanks!

Re the transfer: I think this is a bug in the documentation rather than a discussion question

Oh ok, here are two follow up issues:

1. pest: there is a similar issue that was opened about it: Silent atomic rule #520 (and see: RFC: Make white-space handling less confusing / more consistent with the introduction of an "adjacent selector": , #271 (comment) )
2. book: I re-posted your original issue in the book repository: Potential issue with string example book#23 so that the current behaviour could be better explained in the book
