py-hy: updated to 0.25.0
0.25.0 (released 2022-11-08)
==============================
Breaking Changes
------------------------------
* `dfor` no longer requires brackets around its final arguments, so
`(dfor x (range 5) [x (* 2 x)])` is now `(dfor x (range 5) x (* 2
x))`.
* `except*` (PEP 654) is now recognized in `try`, and a placeholder
macro for `except*` has been added.
Bug Fixes
------------------------------
* `__file__` should now be set the same way as in Python.
* `\N{урж¤` escape sequences are now recognized in f-strings.
* Fixed a bug with `python -O` where assertions were still partly
evaluated.
* Fixed `hy.repr` of `slice` objects with non-integer arguments.
New Features
------------------------------
* Python 3.11 is now supported.
Misc. Improvements
------------------------------
* `hyc` now requires a command-line argument.
* `hyc` prints each path it writes bytecode to, and its messages now
go to standard error instead of standard output.

py-hy: updated to 0.18.0
0.18.0
==============================
Removals
------------------------------
* Python 2 is no longer supported.
* Support for attribute lists in `defclass` has been removed. Use `setv`
and `defn` instead.
* Literal keywords are no longer parsed differently in calls to functions
with certain names.
* `hy.contrib.multi` has been removed. Use `cond` or the PyPI package
`multipledispatch` instead.
Other Breaking Changes
------------------------------
* `HySequence` is now a subclass of `tuple` instead of `list`.
Thus, a `HyList` will never be equal to a `list`, and you can't
use `.append`, `.pop`, etc. on a `HyExpression` or `HyList`.
New Features
------------------------------
* Added special forms `py` to `pys` that allow Hy programs to include
inline Python code.
* Added a special form `cmp` for chained comparisons.
* All augmented assignment operators (except `%=` and `^=`) now allow
more than two arguments.
* Added support for function annotations (PEP 3107) and variable
annotations (PEP 526).
* Added a function `parse-args` as a wrapper for Python's `argparse`.
Bug Fixes
------------------------------
* Statements in the second argument of `assert` are now executed.
* Fixed a bug that caused the condition of a `while` to be compiled
twice.
* `in` and `not-in` now allow more than two arguments, as in Python.
* `hy2py` can now handle format strings.
* Fixed crashes from inaccessible history files.
* Removed an accidental import from the internal Python module `test`.
* Fixed a swarm of bugs in `hy.extra.anaphoric`.
Misc. Improvements
------------------------------
* Replaced the dependency `clint` with `colorama`.
0.17.0
==============================
**Warning**: Hy 0.17.x will be the last Hy versions to support Python 2,
and we expect 0.17.0 to be the only release in this line. By the time
0.18.0 is released (in 2020, after CPython 2 has ceased being developed),
Hy will only support Python 3.
Removals
------------------------------
* Python 3.4 is no longer supported.
New Features
------------------------------
* Python 3.8 is now supported.
* Format strings with embedded Hy code (e.g., `f"The sum is {(+ x y)}"`)
are now supported, even on Pythons earlier than 3.6.
* Added a special form `setx` to create Python 3.8 assignment expressions.
* Added new core functions `list?` and `tuple`.
* Gensyms now have a simpler format that's more concise when
mangled (e.g., `_hyx_XsemicolonXfooXvertical_lineX1235` is now
`_hyx_fooXUffffX1`).
Bug Fixes
------------------------------
* Fixed a crash caused by errors creating temporary files during
bytecode compilation.
0.16.0
==============================
Removals
------------------------------
* Empty expressions (`()`) are no longer legal at the top level.
New Features
------------------------------
* `eval` / `hy_eval` and `hy_compile` now accept an optional `compiler`
argument that enables the use of an existing `HyASTCompiler` instance.
* Keyword objects (not just literal keywords) can be called, as
shorthand for `(get obj :key)`, and they accept a default value
as a second argument.
* Minimal macro expansion namespacing has been implemented. As a result,
external macros no longer have to `require` their own macro
dependencies.
* Macros and tags now reside in module-level `__macros__` and `__tags__`
attributes.
Bug Fixes
------------------------------
* Cleaned up syntax and compiler errors.
* You can now call `defmain` with an empty lambda list.
* `require` now compiles to Python AST.
* Fixed circular `require`\s.
* Fixed module reloading.
* Fixed circular imports.
* Fixed errors from `from __future__ import ...` statements and missing
Hy module docstrings caused by automatic importing of Hy builtins.
* Fixed `__main__` file execution.
* Fixed bugs in the handling of unpacking forms in method calls and
attribute access.
* Fixed crashes on Windows when calling `hy-repr` on date and time
objects.
* Fixed a crash in `mangle` for some pathological inputs.
* Fixed incorrect mangling of some characters at low code points.
* Fixed a crash on certain versions of Python 2 due to changes in the
standard module `tokenize`.
0.15.0
==============================
Removals
------------------------------
* Dotted lists, `HyCons`, `cons`, `cons?`, and `list*` have been
removed. These were redundant with Python's built-in data structures
and Hy's most common model types (`HyExpression`, `HyList`, etc.).
* `&key` is no longer special in lambda lists. Use `&optional` instead.
* Lambda lists can no longer unpack tuples.
* `ap-pipe` and `ap-compose` have been removed. Use threading macros and
`comp` instead.
* `for/a` has been removed. Use `(for [:async ...] ...)` instead.
* `(except)` is no longer allowed. Use `(except [])` instead.
* `(import [foo])` is no longer allowed. Use `(import foo)` instead.
Other Breaking Changes
------------------------------
* `HyExpression`, `HyDict`, and `HySet` no longer inherit from `HyList`.
This means you can no longer use alternative punctuation in place of
square brackets in special forms (e.g. `(fn (x) ...)` instead of
the standard `(fn [x] ...)`).
* Mangling rules have been overhauled; now, mangled names are
always legal Python identifiers.
* `_` and `-` are now equivalent, even as single-character names.
* The REPL history variable `_` is now `*1`.
* Non-shadow unary `=`, `is`, `<`, etc. now evaluate their argument
instead of ignoring it.
* `list-comp`, `set-comp`, `dict-comp`, and `genexpr` have been replaced
by `lfor`, `sfor`, `dfor`, and `gfor`, respectively, which use a new
syntax and have additional features. All Python comprehensions can now
be written in Hy.
* `&`-parameters in lambda lists must now appear in the same order that
Python expects.
* Literal keywords now evaluate to themselves, and `HyKeyword` no longer
inherits from a Python string type
* `HySymbol` no longer inherits from `HyString`.
New Features
------------------------------
* Python 3.7 is now supported.
* `while` and `for` are allowed to have empty bodies.
* `for` supports the various new clause types offered by `lfor`.
* `defclass` in Python 3 supports specifying metaclasses and other
keyword arguments.
* Added `mangle` and `unmangle` as core functions.
* Added more REPL history variables: `*2` and `*3`.
* Added a REPL variable holding the last exception: `*e`.
* Added a command-line option `-E` per CPython.
* Added a new module `hy.model_patterns`.
Bug Fixes
------------------------------
* `hy2py` should now output legal Python code equivalent to the input Hy
code in all cases.
* Fixed `(return)` so it can exit a Python 2 generator.
* Fixed a case where `->` and `->>` duplicated an argument.
* Fixed bugs that caused `defclass` to drop statements or crash.
* Fixed a REPL crash caused by illegal backslash escapes.
* `NaN` can no longer create an infinite loop during macro-expansion.
* Fixed a bug that caused `try` to drop expressions.
* The compiler now properly recognizes `unquote-splice`.
* Trying to import a dotted name is now a syntax error, as in Python.
* `defmacro!` now allows optional arguments.
* Fixed handling of variables that are bound multiple times in a single
`let`.

py-hy: updated to 0.13.0 Changes 0.13.1: [ Language Changes ] * Pythons 2.6, 3.0, 3.1, and 3.2 are no longer supported * let has been removed. Python's scoping rules do not make a proper implementation of it possible. Use setv instead. * lambda has been removed, but fn now does exactly what lambda did * defreader has been renamed to defsharp; what were previously called "reader macros", which were never true reader macros, are now called "sharp macros" * try now enforces the usual Python order for its elements (else must follow all excepts, and finally must come last). This is only a syntactic change; the elements were already run in Python order even when defined out of order. * try now requires an except or finally clause, as in Python * Importing or executing a Hy file automatically byte-compiles it, or loads a byte-compiled version if it exists and is up to date. This brings big speed boosts, even for one-liners, because Hy no longer needs to recompile its standard library for every startup. * Added bytestring literals, which create bytes objects under Python 3 and str objects under Python 2 * Commas and underscores are allowed in numeric literals * Many more operators (e.g., **, //, not, in) can be used as first-class functions * The semantics of binary operators when applied to fewer or more than two arguments have been made more logical * (** a b c d) is now equivalent to (** a (** b (** c d))), not (** (** (** a b) c) d) * setv always returns None * When a try form executes an else clause, the return value for the try form is taken from else instead of the try body. For example, (try 1 (except [ValueError] 2) (else 3)) returns 3. * xor: If exactly one argument is true, return it * hy.core.reserved is now hy.extra.reserved * cond now supports single argument branches [ Bug Fixes ] * All shadowed operators have the same arities as real operators * Shadowed comparison operators now use and instead of & for chained comparisons * partition no longer prematurely exhausts input iterators * read and read-str no longer raise an error when the input parses to a false value (e.g., the empty string) * A yield inside of a with statement will properly suppress implicit returns * setv no longer unnecessarily tries to get attributes * loop no longer replaces string literals equal to "recur" * The REPL now prints the correct value of do and try forms * Fixed a crash when tokenizing a single quote followed by whitespace [ Misc. Improvements ] * New contrib module hy-repr * Added a command-line option --repl-output-fn

Import py27-hy-0.10.0 as lang/py-hy. Hy is a Python <--> Lisp layer. It helps make things work nicer, and lets Python and the Hy lisp variant play nice together.
