Unreleased
|
||
==============================
|
||
|
||
Other Breaking Changes
|
||
------------------------------
|
||
* Mangling rules have been overhauled, such that 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. This change increases consistency a bit
|
||
and makes accidental unary uses easier to notice.
|
||
|
||
New Features
|
||
------------------------------
|
||
* Added `mangle` and `unmangle` as core functions
|
||
|
||
Bug Fixes
|
||
------------------------------
|
||
* Fix `(return)` so it works correctly to exit a Python 2 generator
|
||
|
||
Other Breaking Changes
|
||
-----------------------------
|
||
* `hy-repr` uses registered functions instead of methods
|
||
|
||
Misc. Improvements
|
||
----------------------------
|
||
* `hy-repr` supports more standard types
|
||
|
||
0.14.0
|
||
==============================
|
||
|
||
Removals
|
||
------------------------------
|
||
* Python 3.3 is no longer supported
|
||
* `def` is gone; use `setv` instead
|
||
* `apply` is gone; use the new `#*` and `#**` syntax instead
|
||
* `yield-from` is no longer supported under Python 2
|
||
* Periods are no longer allowed in keywords
|
||
* Numeric literals can no longer begin with a comma or underscore
|
||
* Literal `Inf`\s and `NaN`\s must now be capitalized like that
|
||
|
||
Other Breaking Changes
|
||
------------------------------
|
||
* Single-character "sharp macros" are now "tag macros", which can have
|
||
longer names
|
||
* `xi` from `hy.extra.anaphoric` is now a tag macro `#%`
|
||
* `eval` is now a function instead of a special form
|
||
|
||
New Features
|
||
------------------------------
|
||
* The compiler now automatically promotes values to Hy model objects
|
||
as necessary, so you can write ``(eval `(+ 1 ~n))`` instead of
|
||
``(eval `(+ 1 ~(HyInteger n)))``
|
||
* `return` has been implemented as a special form
|
||
* Added a form of string literal called "bracket strings" delimited by
|
||
`#[FOO[` and `]FOO]`, where `FOO` is customizable
|
||
* Added support for PEP 492 (`async` and `await`) with `fn/a`, `defn/a`,
|
||
`with/a`, and `for/a`
|
||
* Added Python-style unpacking operators `#*` and `#**` (e.g.,
|
||
`(f #* args #** kwargs)`)
|
||
* Added a macro `comment`
|
||
* Added EDN `#_` syntax to discard the next term
|
||
* `while` loops may now contain an `else` clause, like `for` loops
|
||
* `#%` works on any expression and has a new `&kwargs` parameter `%**`
|
||
* Added a macro `doc` and a tag macro `#doc`
|
||
* `get` is available as a function
|
||
* `~@` (`unquote-splice`) form now accepts any false value as empty
|
||
|
||
Bug Fixes
|
||
------------------------------
|
||
* Relative imports (PEP 328) are now allowed
|
||
* Numeric literals are no longer parsed as symbols when followed by a dot
|
||
and a symbol
|
||
* Hy now respects the environment variable `PYTHONDONTWRITEBYTECODE`
|
||
* String literals should no longer be interpreted as special forms or macros
|
||
* Tag macros (née sharp macros) whose names begin with `!` are no longer
|
||
mistaken for shebang lines
|
||
* Fixed a bug where REPL history wasn't saved if you quit the REPL with
|
||
`(quit)` or `(exit)`
|
||
* `exec` now works under Python 2
|
||
* No TypeError from multi-arity `defn` returning values evaluating to `None`
|
||
* `try` forms are now possible in `defmacro` and `deftag`
|
||
* Multiple expressions are now allowed in `try`
|
||
* Fixed a crash when `macroexpand`\ing a macro with a named import
|
||
* Fixed a crash when `with` suppresses an exception. `with` now returns
|
||
`None` in this case.
|
||
* Fixed a crash when `--repl-output-fn` raises an exception
|
||
* Fixed a crash when `HyTypeError` was raised with objects that had no
|
||
source position
|
||
* `assoc` now evaluates its arguments only once each
|
||
* Multiple expressions are now allowed in the `else` clause of
|
||
a `for` loop
|
||
* `else` clauses in `for` and `while` are recognized more reliably
|
||
* Statements in the condition of a `while` loop are repeated properly
|
||
* Argument destructuring no longer interferes with function docstrings
|
||
* Nullary `yield-from` is now a syntax error
|
||
* `break` and `continue` now raise an error when given arguments
|
||
instead of silently ignoring them
|
||
|
||
Misc. Improvements
|
||
------------------------------
|
||
* `read`, `read_str`, and `eval` are exposed and documented as top-level
|
||
functions in the `hy` module
|
||
* An experimental `let` macro has been added to `hy.contrib.walk`
|
||
|
||
0.13.1
|
||
==============================
|
||
|
||
Bug Fixes
|
||
------------------------------
|
||
* Changed setup.py to require astor 0.5, since 0.6 isn't
|
||
backwards-compatible.
|
||
|
||
0.13.0
|
||
==============================
|
||
|
||
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 `except`\s, 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`
|
||
|
||
0.12.1
|
||
==============================
|
||
|
||
Bug Fixes
|
||
------------------------------
|
||
* Allow installation without Git
|
||
|
||
0.12.0
|
||
==============================
|
||
|
||
This release brings some quite significant changes on the language and as a
|
||
result very large portions of previously written Hy programs will require
|
||
changes. At the same time, documentation and error messages were improved,

Changes from 0.9.12
|
||
==============================
|
||
|
||
0.10.0 - the "oh man I'm late for PyCon" release

||
- Hy Society
|
||
|
||
Breaking Changes
|
||
------------------------------
|
||
|
||
We're calling this release 0.10 because we broke
|
||
API. Sorry about that. We've removed kwapply in
|
||
favor of using `apply`. Please be sure to upgrade
|
||
all code to work with `apply`.
|
||
|
||
(apply function-call args kwargs) ; is the signature
|
||
|
||
Thanks
|
||
------------------------------
|
||
|
||
Major shoutout to Clinton Dreisbach for implementing loop/recur.
|
||
As always, massive hugs to olasd for the constant reviews and for
|
||
implementing HyCons cells. Thanks to @kenanb for redesigning the
|
||
new Hy logo.
|
||
|
||
Many thanks to algernon for working on adderall, which helped
|
||
push Hy further this cycle. Adderall is an implementation of miniKanren
|
||
in Hy. If you're interested in using Adderall, check out hydiomatic,
|
||
which prettifies Hy source using Adderall rules.
|
||
|
||
This release saw an increase of about 11 contributors for a point
|
||
release, you guys rock!

|
||
|
||
Language Changes

||
------------------------------
|
||
|
||
* `for` revamped again (Last time, we hope!), this time using a saner
|
||
itertools.product when nesting
|
||
* `lisp-if`/`lif` added for the lisp-like everything is true if, giving
|
||
seasoned lispers a better if check (0 is a value, etc)
|
||
* Reader Macros are macros now!
|
||
* yield-from is now a proper yield from on Python 3. It also now breaks on
|
||
Python 2.x.
|
||
* Added if-not macro
|
||
* We finally have a lisp like cons cells
|
||
* Generator expressions, set & dict comprehensions are now supported
|
||
* (.) is a mini DSL for attribute access
|
||
* `macroexpand` & `macroexpand-1` added to core
|
||
* `disassemble` added to core, which dumps the AST or equivalent python code
|
||
* `coll?` added to core to check for a collection
|
||
* `identity` function added to core
|
||
|
||
Misc. Fixes

||
------------------------------
|
||
* Lots of doc fixes. Reorganization as well as better docs on Hy internals

|
||
separately
|
||
|
||
Bug Fixes
|
||
------------------------------
|
||
* Empty MacroExpansions work as expected
|
||
* Python 3.4 port. Sorry this wasn't in a 3.4 release time, we forgot to do

|
||
Changes from Hy 0.9.11
|
||
==============================
|
||
|
||
tl;dr:
|
||
|
||
0.9.12 comes with some massive changes,
|
||
We finally took the time to implement gensym, as well as a few
|
||
other bits that help macro writing. Check the changelog for
|
||
what exactly was added.
|
||
|
||
The biggest feature, Reader Macros, landed later
|
||
in the cycle, but were big enough to warrant a release on its
|
||
own. A huge thanks goes to Foxboron for implementing them
|
||
and a massive hug goes out to olasd for providing ongoing
|
||
reviews during the development.
|
||
|
||

||
Syntax Fixes
|
||
------------------------------
|

|

|
||
* Allow empty (do) forms (JD)
|
||

WARNING: WARNING: READ ME: READ ME:
|
||
-----------------------------------
|
||
|
||
From here on out, we will only support "future division" as part of hy.
|
||
This is actually quite a pain for us, but it's going to be quite an
|
||
amazing feature.
|
||
|
||
This also normalizes behavior from Py 2 --> Py 3.
|
||
|
||
Thank you so much, Konrad Hinsen.
|
||
|
||
Language Changes
|
||
------------------------------
|
||
|
||
* (pass) has been removed from the language; it's a wart that comes from
|
||
a need to create valid Python syntax without breaking the whitespace
|
||
bits. (JD)
|
||
* We've moved to a new import style, (import-from) and (import-as) will
|
||
be removed before 1.0. (GN)

|
||
* Prototypes for eval (PT)
|
||

|
||
* Statements in the `fn` path early will not return anymore. (PT)

||
