Hare 0.24.2
This is the stable release of Hare 0.24.2. Highlights of this release
include:
* NetBSD support
* for-each loops and the "done" type
* Optional parameters for functions
* Support for shared memory and memfds on supported platforms
* Revised and improved APIs for unix::*
* Improved performance for bufio and related APIs
* regex:: now supports multiple alternation (i.e. (x|y|z))
* New cryptography APIs:
* crypto::ec
* crypto::ecdh
* crypto::ecdsa
This release includes a number of breaking changes.
The introduction of the "done" type to improve the iterator pattern
introduces the following changes:
* "done" is now a reserved word and cannot be used in user-defined names
* The following standard library symbols have been updated to use done
types in their API:
* bytes::next_token/bytes::prev_token
* encoding::utf8
* fs::next
* glob::next
* io::EOF
* mime
* path::nextiter
* strings::next/strings::prev
* strings::next_token/strings::prev_token
* In short, if your program matches on a function using the iterator
pattern with "void" and this causes an error from 0.24.2, the
correct solution is likely to rewrite it to use a for-each loop, or
replace "void" with "done" in the relevant match case.
bytes::tokenize now accepts multiple single-byte delimiters and removes
support for multi-byte delimiters. strings::tokenize accepts multiple
delimiters, limited to the set of ASCII characters.
The following APIs have been overhauled and programs depending on them
may need to be refactored:
* unix::hosts
* unix::passwd
Several breaking changes have been made to time:
* time::date now accepts a zone offset (zoff) parameter in
time::date::reckon and time::date::truncate.
* time::date::calculus has been renamed to time::date::rflag.
* time::date::realize requires .vloc to be set, and no longer defaults
to UTC.
* time::date::now() is renamed to time::date::localnow() and
time::date::nowutc() is renamed to time::date::now()
* time::date::EPOCHAL_JULIAN and EPOCHAL_GREGORIAN have been renamed to
EPOCHDAY_JULIAN and EPOCHDAY_GREGORIAN respectively
* time::chrono::eq has been removed and replaced with
time::chrono::simultaneous and time::chrono::coincident
* time::chrono::mzone has been renamed to time::chrono::ozone
* The type of time::date::parsefail has been chnaged from rune (storing
the offending format specifier) to (size, rune), which adds the index
of the position where the parsing failure occured.
* Several constants for format layouts in time::date have been renamed:
[[EMAILZ]] => [[EMAILZONE]]
[[STAMP_NANO]] => [[STAMPNANO]]
[[STAMP_ZOFF]] => [[STAMPZOFF]]
[[STAMP_ZONE]] => [[STAMPZONE]]
[[STAMP_NOZL]] => [[STAMPLOC]]
strconv's "b" family of functions (those which accept a base for the
conversion) have been removed, and the remaining functions accept the
desired base as an optional parameter.
The following modules have been removed from the standard library and
placed in the extended library:
* crypto::bcrypt
https://git.sr.ht/~sircmpwn/hare-bcrypt
* format::tar
https://git.sr.ht/~sircmpwn/hare-tar
