Josuah Demangeon a0307c343d docs: disambiguate Cat(a, b, ...) support for more than 2 arguments 
I had this confusion while reading the doc.

Someone else also likely did:

Catherine 80343d1c4c hdl.ast: warn on fencepost error in Signal(range(x), reset=x). 
Also, relax the language reference inset from "warning" to "note"
since this is no longer something developers have to keep in mind
explicitly.
 2023-03-13 20:38:41 +00:00
Catherine 32eabd9372 hdl.ast: remove Value.__hash__. 
This is already undefined when defining `Value.__eq__`, and it makes
typecheckers (mypy, pyright/pylance) unhappy.

Catherine ae1aeff0f2 lib.data: at most one Union field can have annotation with a default. 2023-03-04 09:34:50 +00:00
Jonathan Neuschäfer e2ce959c90 build.run: Handle UTF-8 encoding errors in SSH output gracefully 
In some cases, a toolchain might produce shell output that isn't correct
UTF-8. To avoid crashing in such cases, pass errors="replace" to
bytes.decode.

For example, Lattice Diamond uses the Latin-1 encoding for some reason.
This recently broke my setup because the month turned to "März" in a
German locale:

--- Start Time: Fr. M�r 3 20:01:41 2023

Catherine 16be75e02c lib.data: fix typo. 2023-03-03 09:03:53 +00:00
Catherine 0c4fda92fe hdl.ast: accept any constant-castable expression in Signal(reset=). 
See amaranth-lang/rfcs#4.

This functionality was not explicitly specified in the RFC but it
falls under "anywhere an integer or an enumeration is accepted".
 2023-03-03 06:22:56 +00:00
Catherine f77a335abf lib.enum: change shape mismatch warning category to SyntaxWarning. 2023-03-03 06:14:53 +00:00
Catherine c1b9c64e10 lib.data: ignore Python typing annotations in aggregate base class. 2023-03-03 03:45:12 +00:00
mndza 90b374c17a build.plat: fix strings as build option overrides. 
This was broken in 097da99.
 2023-03-02 10:50:14 +00:00
Marcelina Kościelnicka e3e542afff vendor.xilinx: fix a SyntaxWarning. 2023-03-01 00:51:13 +00:00
Catherine 14e73a73de hdl.ast: do not cast comparand to shape in Shape.__eq__. 
This doesn't match how other Python comparison operators work.
E.g. `1 == int("1")` but `1 != "1"`.
 2023-02-28 15:52:50 +00:00
Catherine 35561ea11a lib.data: improve reset value handling for Union. 
* Reject union initialization with more than one reset value.
* Replace the reset value specified in the class definition with
  the one provided during initalization instead of merging.
 2023-02-28 15:38:20 +00:00
Catherine c7ef05c894 lib.data: improve annotation handling for Struct and Union. 
* Annotations like `s: unsigned(4) = 1` are recognized and
  the assigned value is used as the reset value for the implicitly
  created `Signal`.
* Base classes inheriting from `Struct` and `Union` without
  specifying a layout are recognized.
* Classes that both inherit from a base class with a layout and
  specify a layout are rejected.

Catherine 0ee5de036c hdl.ast: deprecate Sample, Past, Rose, Fell, Stable. 
See #526.
 2023-02-28 14:30:04 +00:00
Catherine 9ec7f5b507 build.plat: accept lists as build option overrides. 
This was unintentionally removed in 9eb208c3.

Fixes #727.
 2023-02-28 13:40:59 +00:00
Catherine 0b7adcbd10 back.verilog: pass -norom to -proc if available. 
Fixes #746.
 2023-02-28 13:34:14 +00:00
Catherine 7ea2e175e4 lib.enum: fix shape calculation for const-castable member values. 2023-02-28 13:30:26 +00:00
Catherine de36e3c162 lib.enum: add Python 3.7..3.8 compatibility shim. 2023-02-28 13:26:52 +00:00
Catherine 57612f1dce lib.enum: add Enum wrappers that allow specifying shape. 
See #756 and amaranth-lang/rfcs#3.
 2023-02-28 13:00:41 +00:00
Catherine ef2e9fa809 hdl.ast: Value.matches() with no arguments should return C(1). 
The behavior of the following must be always the same:
- `with m.Switch(v): with m.Case(*pats):`
- `with m.If(v.matches(*pats)):`

Catherine 342fd5f8bd docs: fix doctests and run them in CI workflow. 2023-02-27 19:47:51 +00:00
Catherine 5d872096a7 docs/changes: link to RFC. 2023-02-27 18:28:52 +00:00
Catherine f602ce1f8f hdl.ast: deprecate Const.normalize. 
Tracking issue #754.
 2023-02-27 18:19:59 +00:00
Catherine fcc4f54367 lib.data: make Field() immutable. 
Mutability of Field isn't specified by the RFC and can cause issues
if the objects stored in Layout subclasses are mutated. There isn't
any reason to do that (the subclasses themselves are mutable and
handle that correctly), so disallow it.

hdl,back: add support for name= in property checks (Assert, ...).

Fixes #665.

Catherine dafefa87a9 build.run: in BuildPlan.execute_local, always use LF line endings.

Fixes #732.

Catherine 897400ee59 pyproject: relax amaranth-yosys dependency. 2023-02-03 02:40:25 +00:00
Catherine 37623c69a0 Configure git-archive to export information for setuptools_scm. 
This requires git>=2.32.0.
 2023-02-02 23:43:33 +00:00
Catherine 732d62eb24 Move most of setup.py to pyproject.toml. 
The custom setuptools_scm configuration is removed. It was buggy (for
the case of a dirty worktree exactly at the tag, it did not append
`+dirty`) and otherwise is only different from node-and-timestamp by
appending `.dirty` instead of `.dYYYYMMDDHHMMSS`. The latter is
preferable anyway.
