Hi,
After attempting the following:
--8<---------------cut here---------------start------------->8---
(match (string-split "./Bootloaders/Printer/Documentation/html" #\/)
(("." path ..1 "Documentation" "html")
For a start, where does that "..1" syntax come from? To my knowledge, no such syntax is supported by Guile's pattern matcher, which AFAIK is the one described in SRFI-204.
So your example is just binding the string "Printer" to the variable "..1": since "..1" doesn't have any special meaning, it's just a pattern variable.
(pk 'path path)))
=> ;;; (path "Bootloaders")
Expected (and works with '...'):
;;; (path "Bootloaders" "Printer")
--8<---------------cut here---------------end--------------->8---
and asking about it in #scheme or #guile, it seems the '..1' and '...'
patterns *must* be used strictly to match at the end of lists,
??
This is not what SRFI 204 says, and it's not consistent with syntax-rules and syntax-case patterns either.
