Scheme Request for Implementation 192,
"Port Positioning,"
by The R6RS editors; John Cowan (shepherd); Shiro Kawai (implementation; requires a hook),
has gone into FINAL status.

The document and an archive of the discussion are available at <https://srfi.schemers.org/srfi-192/>.

Here's the abstract:

This is an extract from the R6RS that documents its support for
positioning ports. Binary ports can be positioned to read or write at
a specific byte; textual ports at a specific character, although
character positions can't be synthesized portably. It has been lightly
edited to fit R7RS style.

Here is the commit summary since the most recent draft:

- Implement i/o-invalid-position-error
- Fixed explanation of implementations, added Shiro as author
- input ports can seek past the end too
- Fix typo.
- Add Shiro as co-author.
- Remove extra parentheses.
- Switch to new official SRFI header format.
- Fix errors reported by W3C HTML Validator.
- formatting
- editorial
- copy edits
- Finalize.

Here are the diffs since the most recent draft:
