# GitHub Copilot Instructions for RustPython
This document provides guidelines for working with GitHub Copilot when contributing to the RustPython project.
## Project Overview
RustPython is a Python 3 interpreter written in Rust, implementing Python 3.13.0+ compatibility. The project aims to provide:
- A complete Python-3 environment entirely in Rust (not CPython bindings)
- A clean implementation without compatibility hacks
- Cross-platform support, including WebAssembly compilation
- The ability to embed Python scripting in Rust applications
## Repository Structure
- `src/` - Top-level code for the RustPython binary
- `vm/` - The Python virtual machine implementation
- `builtins/` - Python built-in types and functions
- `stdlib/` - Essential standard library modules implemented in Rust, required to run the Python core
- `compiler/` - Python compiler components
- `parser/` - Parser for converting Python source to AST
- `core/` - Bytecode representation in Rust structures
- `codegen/` - AST to bytecode compiler
- `Lib/` - CPython's standard library in Python (copied from CPython). **IMPORTANT**: Do not edit this directory directly; The only allowed operation is copying files from CPython.
- `derive/` - Rust macros for RustPython
- `common/` - Common utilities
- `extra_tests/` - Integration tests and snippets
- `stdlib/` - Non-essential Python standard library modules implemented in Rust (useful but not required for core functionality)
- `wasm/` - WebAssembly support
- `jit/` - Experimental JIT compiler implementation
- `pylib/` - Python standard library packaging (do not modify this directory directly - its contents are generated automatically)
## Important Development Notes
### Running Python Code
When testing Python code, always use RustPython instead of the standard `python` command:
```bash
# Use this instead of python script.py
cargo run -- script.py
# For interactive REPL
cargo run
# With specific features
cargo run --features ssl
# Release mode (recommended for better performance)
cargo run --release -- script.py
```
### Comparing with CPython
When you need to compare behavior with CPython or run test suites:
```bash
# Use python command to explicitly run CPython
python my_test_script.py
# Run RustPython
cargo run -- my_test_script.py
```
### Working with the Lib Directory
The `Lib/` directory contains Python standard library files copied from the CPython repository. Important notes:
- These files should be edited very conservatively
- Modifications should be minimal and only to work around RustPython limitations
- Tests in `Lib/test` often use one of the following markers:
- Add a `# TODO: RUSTPYTHON` comment when modifications are made
- `unittest.skip("TODO: RustPython <reason>")`
- `unittest.expectedFailure` with `# TODO: RUSTPYTHON <reason>` comment
### Testing
```bash
# Run Rust unit tests
cargo test --workspace --exclude rustpython_wasm
# Run Python snippets tests
cd extra_tests
pytest -v
# Run the Python test module
cargo run --release -- -m test ${TEST_MODULE}
cargo run --release -- -m test test_unicode # to test test_unicode.py
# Run the Python test module with specific function
cargo run --release -- -m test test_unicode -k test_unicode_escape
```
### Determining What to Implement
Run `./whats_left.py` to get a list of unimplemented methods, which is helpful when looking for contribution opportunities.
## Coding Guidelines
### Rust Code
- Follow the default rustfmt code style (`cargo fmt` to format)
- **IMPORTANT**: Always run clippy to lint code (`cargo clippy`) before completing tasks. Fix any warnings or lints that are introduced by your changes
- Follow Rust best practices for error handling and memory management
- Use the macro system (`pyclass`, `pymodule`, `pyfunction`, etc.) when implementing Python functionality in Rust
### Python Code
- **IMPORTANT**: In most cases, Python code should not be edited. Bug fixes should be made through Rust code modifications only
- Follow PEP 8 style for custom Python code
- Use ruff for linting Python code
- Minimize modifications to CPython standard library files
## Integration Between Rust and Python
The project provides several mechanisms for integration:
- `pymodule` macro for creating Python modules in Rust
- `pyclass` macro for implementing Python classes in Rust
- `pyfunction` macro for exposing Rust functions to Python
- `PyObjectRef` and other types for working with Python objects in Rust
## Common Patterns
### Implementing a Python Module in Rust
```rust
#[pymodule]
mod mymodule {
use rustpython_vm::prelude::*;
#[pyfunction]
fn my_function(value: i32) -> i32 {
value * 2
}
#[pyattr]
#[pyclass(name = "MyClass")]
#[derive(Debug, PyPayload)]
struct MyClass {
value: usize,
}
#[pyclass]
impl MyClass {
#[pymethod]
fn get_value(&self) -> usize {
self.value
}
}
}
```
### Adding a Python Module to the Interpreter
```rust
vm.add_native_module(
"my_module_name".to_owned(),
Box::new(my_module::make_module),
);
```
## Building for Different Targets
### WebAssembly
```bash
# Build for WASM
cargo build --target wasm32-wasip1 --no-default-features --features freeze-stdlib,stdlib --release
```
### JIT Support
```bash
# Enable JIT support
cargo run --features jit
```
### SSL Support
```bash
# Enable SSL support
cargo run --features ssl
```
## Test Code Modification Rules
**CRITICAL: Test code modification restrictions**
- NEVER comment out or delete any test code lines except for removing `@unittest.expectedFailure` decorators and upper TODO comments
- NEVER modify test assertions, test logic, or test data
- When a test cannot pass due to missing language features, keep it as expectedFailure and document the reason
- The only acceptable modifications to test files are:
1. Removing `@unittest.expectedFailure` decorators and the upper TODO comments when tests actually pass
2. Adding `@unittest.expectedFailure` decorators when tests cannot be fixed
**Examples of FORBIDDEN modifications:**
- Commenting out test lines
- Changing test assertions
- Modifying test data or expected results
- Removing test logic
**Correct approach when tests fail due to unsupported syntax:**
- Keep the test as `@unittest.expectedFailure`
- Document that it requires PEP 695 support
- Focus on tests that can be fixed through Rust code changes only
## Documentation
- Check the [architecture document](architecture/architecture.md) for a high-level overview
- Read the [development guide](DEVELOPMENT.md) for detailed setup instructions
- Generate documentation with `cargo doc --no-deps --all`
- Online documentation is available at [docs.rs/rustpython](https://docs.rs/rustpython/)

```shell
$ cd extra_tests
$ cd tests
$ pytest -v
```
Rust unit tests can be run with `cargo`:
```shell
$ cargo test --workspace --exclude rustpython_wasm
```
Python unit tests can be run by compiling RustPython and running the test module:
```shell
$ cargo run --release -- -m test
```
There are a few test options that are especially useful:
- `-j <n>` enables parallel testing (which is a lot faster), where `<n>` is the
number of threads to be used, ideally the same as number of cores on your CPU.
If you don't know, `-j 4` or `-j 8` are good options.
- `-v` enables verbose mode, adding additional information about the tests being
run.
- `<test_name>` specifies a single test to run instead of running all tests.
For example, to run all tests in parallel:
```shell
$ cargo run --release -- -m test -j 4
```
To run only `test_cmath` (located at `Lib/test/test_cmath`) verbosely:
```shell
$ cargo run --release -- -m test test_cmath -v
$ cargo test --all

### Code generation
There are some code generations involved in building RustPython:
- some part of the AST code is generated from `vm/src/stdlib/ast/gen.rs` to `compiler/ast/src/ast_gen.rs`.
- the `__doc__` attributes are generated by the
[__doc__](https://github.com/RustPython/__doc__) project which is then included as the `rustpython-doc` crate.

############ Maintenance notes #########################################
#
# ABCs are different from other standard library modules in that they
# specify compliance tests. In general, once an ABC has been published,
# new methods (either abstract or concrete) cannot be added.
#
# Though classes that inherit from an ABC would automatically receive a
# new mixin method, registered classes would become non-compliant and
# violate the contract promised by ``isinstance(someobj, SomeABC)``.
#
# Though irritating, the correct procedure for adding new abstract or
# mixin methods is to create a new ABC as a subclass of the previous
# ABC. For example, union(), intersection(), and difference() cannot
# be added to Set but could go into a new ABC that extends Set.
#
# Because they are so hard to change, new ABCs should have their APIs
# carefully thought through prior to publication.
#
# Since ABCMeta only checks for the presence of methods, it is possible
# to alter the signature of a method by adding optional arguments
# or changing parameters names. This is still a bit dubious but at
# least it won't cause isinstance() to return an incorrect result.

"""Python decimal arithmetic module"""
"""
This is an implementation of decimal floating point arithmetic based on
the General Decimal Arithmetic Specification:
http://speleotrove.com/decimal/decarith.html
and IEEE standard 854-1987:
http://en.wikipedia.org/wiki/IEEE_854-1987
Decimal floating point has finite precision with arbitrarily large bounds.
The purpose of this module is to support arithmetic using familiar
"schoolhouse" rules and to avoid some of the tricky representation
issues associated with binary floating point. The package is especially
useful for financial applications or for contexts where users have
expectations that are at odds with binary floating point (for instance,
in binary floating point, 1.00 % 0.1 gives 0.09999999999999995 instead
of 0.0; Decimal('1.00') % Decimal('0.1') returns the expected
Decimal('0.00')).
Here are some examples of using the decimal module:
>>> from decimal import *
>>> setcontext(ExtendedContext)
>>> Decimal(0)
Decimal('0')
>>> Decimal('1')
Decimal('1')
>>> Decimal('-.0123')

Decimal('123456')
>>> Decimal('123.45e12345678')
Decimal('1.2345E+12345680')
>>> Decimal('1.33') + Decimal('1.27')
Decimal('2.60')
>>> Decimal('12.34') + Decimal('3.87') - Decimal('18.41')
Decimal('-2.20')
>>> dig = Decimal(1)

# To summarise the summary of the summary:- people are a problem.
# -- The Hitch-Hikers Guide to the Galaxy, Episode 12
#### Desired behaviour of the completions commands.
# the considerations are:
# (1) how many completions are possible
# (2) whether the last command was a completion
# (3) if we can assume that the completer is going to return the same set of
# completions: this is controlled by the ``assume_immutable_completions``
# variable on the reader, which is True by default to match the historical
# behaviour of pyrepl, but e.g. False in the ReadlineAlikeReader to match
# more closely readline's semantics (this is needed e.g. by
# fancycompleter)
#
# if there's no possible completion, beep at the user and point this out.
# this is easy.
#
# if there's only one possible completion, stick it in. if the last thing
# user did was a completion, point out that he isn't getting anywhere, but
# only if the ``assume_immutable_completions`` is True.
#
# now it gets complicated.
#
# for the first press of a completion key:
# if there's a common prefix, stick it in.
# irrespective of whether anything got stuck in, if the word is now
# complete, show the "complete but not unique" message
# if there's no common prefix and if the word is not now complete,
# beep.
# common prefix -> yes no
# word complete \/
# yes "cbnu" "cbnu"
# no - beep
# for the second bang on the completion key
# there will necessarily be no common prefix
# show a menu of the choices.
# for subsequent bangs, rotate the menu around (if there are sufficient
# choices).

"""
Keymap contains functions for parsing keyspecs and turning keyspecs into
appropriate sequences.
A keyspec is a string representing a sequence of key presses that can
be bound to a command. All characters other than the backslash represent
themselves. In the traditional manner, a backslash introduces an escape
sequence.
pyrepl uses its own keyspec format that is meant to be a strict superset of
readline's KEYSEQ format. This means that if a spec is found that readline
accepts that this doesn't, it should be logged as a bug. Note that this means
we're using the `\\C-o' style of readline's keyspec, not the `Control-o' sort.
The extension to readline is that the sequence \\<KEY> denotes the
sequence of characters produced by hitting KEY.
Examples:
`a' - what you get when you hit the `a' key
`\\EOA' - Escape - O - A (up, on my terminal)
`\\<UP>' - the up arrow key
`\\<up>' - ditto (keynames are case-insensitive)
`\\C-o', `\\c-o' - control-o
`\\M-.' - meta-period
`\\E.' - ditto (that's how meta works for pyrepl)
`\\<tab>', `\\<TAB>', `\\t', `\\011', '\\x09', '\\X09', '\\C-i', '\\C-I'
- all of these are the tab character.

class Reader:
"""The Reader class implements the bare bones of a command reader,
handling such details as editing and cursor motion. What it does
not support are such things as completion or history support -
these are implemented elsewhere.
Instance variables of note include:
* buffer:
A *list* (*not* a string at the moment :-) containing all the
characters that have been entered.
* console:
Hopefully encapsulates the OS dependent stuff.
* pos:
A 0-based index into `buffer' for where the insertion point
is.
* screeninfo:
Ahem. This list contains some info needed to move the
insertion point around reasonably efficiently.
* cxy, lxy:
the position of the insertion point in screen ...
* syntax_table:
Dictionary mapping characters to `syntax class'; read the
emacs docs to see what this means :-)
* commands:
Dictionary mapping command names to command classes.
* arg:
The emacs-style prefix argument. It will be None if no such
argument has been provided.
* dirty:
True if we need to refresh the display.
* kill_ring:
The emacs-style kill-ring; manipulated with yank & yank-pop
* ps1, ps2, ps3, ps4:
prompts. ps1 is the prompt for a one-line input; for a
multiline input it looks like:
ps2> first line of input goes here
ps3> second and further
ps3> lines get ps3
...
ps4> and the last one gets ps4
As with the usual top-level, you can set these to instances if
you like; str() will be called on them (once) at the beginning
of each command. Don't put really long or newline containing
strings here, please!
This is just the default policy; you can change it freely by
overriding get_prompt() (and indeed some standard subclasses
do).
* finished:
handle1 will set this to a true value if a command signals
that we're done.

class. Depending on the version of Python you're using, there may be a
faster one available. You should always import the `local` class from
`threading`.)
Thread-local objects support the management of thread-local data.
If you have data that you want to be local to a thread, simply create
a thread-local object and use its attributes:
>>> mydata = local()
>>> mydata.number = 42
>>> mydata.number
42
You can also access the local-object's dictionary:
>>> mydata.__dict__
{'number': 42}
>>> mydata.__dict__.setdefault('widgets', [])
[]
>>> mydata.widgets
[]
What's important about thread-local objects is that their data are
local to a thread. If we access the data in a different thread:
>>> log = []
>>> def f():
... items = sorted(mydata.__dict__.items())
... log.append(items)
... mydata.number = 11
... log.append(mydata.number)
>>> import threading
>>> thread = threading.Thread(target=f)
>>> thread.start()
>>> thread.join()
>>> log
[[], 11]
we get different data. Furthermore, changes made in the other thread
don't affect data seen in this thread:
>>> mydata.number
42
Of course, values you get from a local object, including a __dict__
attribute, are for whatever thread was current at the time the
attribute was read. For that reason, you generally don't want to save
these values across threads, as they apply only to the thread they
came from.
You can create custom local objects by subclassing the local class:
>>> class MyLocal(local):
... number = 2
... initialized = False
... def __init__(self, **kw):
... if self.initialized:
... raise SystemError('__init__ called too many times')
... self.initialized = True
... self.__dict__.update(kw)
... def squared(self):
... return self.number ** 2
This can be useful to support default values, methods and
initialization. Note that if you define an __init__ method, it will be
called each time the local object is used in a separate thread. This
is necessary to initialize each thread's dictionary.
Now if we create a local object:
>>> mydata = MyLocal(color='red')
Now we have a default number:
>>> mydata.number
2
an initial color:
>>> mydata.color
'red'
>>> del mydata.color
And a method that operates on the data:
>>> mydata.squared()
4
As before, we can access the data in a separate thread:
>>> log = []
>>> thread = threading.Thread(target=f)
>>> thread.start()
>>> thread.join()
>>> log
[[('color', 'red'), ('initialized', True)], 11]
without affecting this thread's data:
>>> mydata.number
2
>>> mydata.color
Traceback (most recent call last):
...
AttributeError: 'MyLocal' object has no attribute 'color'
Note that subclasses can define slots, but they are not thread
local. They are shared across threads:
>>> class MyLocal(local):
... __slots__ = 'number'
>>> mydata = MyLocal()
>>> mydata.number = 42
>>> mydata.color = 'red'
So, the separate thread:
>>> thread = threading.Thread(target=f)
>>> thread.start()
>>> thread.join()
affects what we see:
>>> # TODO: RUSTPYTHON, __slots__
>>> mydata.number #doctest: +SKIP
11
>>> del mydata

"""Stuff to parse AIFF-C and AIFF files.
Unless explicitly stated otherwise, the description below is true
both for AIFF-C files and AIFF files.
An AIFF-C file has the following structure.
+-----------------+
| FORM |
+-----------------+
| <size> |
+----+------------+
| | AIFC |
| +------------+
| | <chunks> |
| | . |
| | . |
| | . |
+----+------------+
An AIFF file has the string "AIFF" instead of "AIFC".
A chunk consists of an identifier (4 bytes) followed by a size (4 bytes,
big endian order), followed by the data. The size field does not include
the size of the 8 byte header.
The following chunk types are recognized.
FVER
<version number of AIFF-C defining document> (AIFF-C only).
MARK
<# of markers> (2 bytes)
list of markers:
<marker ID> (2 bytes, must be > 0)
<position> (4 bytes)
<marker name> ("pstring")
COMM
<# of channels> (2 bytes)
<# of sound frames> (4 bytes)
<size of the samples> (2 bytes)
<sampling frequency> (10 bytes, IEEE 80-bit extended
floating point)
in AIFF-C files only:
<compression type> (4 bytes)
<human-readable version of compression type> ("pstring")
SSND
<offset> (4 bytes, not used by this program)
<blocksize> (4 bytes, not used by this program)
<sound data>
A pstring consists of 1 byte length, a string of characters, and 0 or 1
byte pad to make the total length even.
Usage.
Reading AIFF files:
f = aifc.open(file, 'r')
where file is either the name of a file or an open file pointer.
The open file pointer must have methods read(), seek(), and close().
In some types of audio files, if the setpos() method is not used,
the seek() method is not necessary.
This returns an instance of a class with the following public methods:
getnchannels() -- returns number of audio channels (1 for
mono, 2 for stereo)
getsampwidth() -- returns sample width in bytes
getframerate() -- returns sampling frequency
getnframes() -- returns number of audio frames
getcomptype() -- returns compression type ('NONE' for AIFF files)
getcompname() -- returns human-readable version of
compression type ('not compressed' for AIFF files)
getparams() -- returns a namedtuple consisting of all of the
above in the above order
getmarkers() -- get the list of marks in the audio file or None
if there are no marks
getmark(id) -- get mark with the specified id (raises an error
if the mark does not exist)
readframes(n) -- returns at most n frames of audio
rewind() -- rewind to the beginning of the audio stream
setpos(pos) -- seek to the specified position
tell() -- return the current position
close() -- close the instance (make it unusable)
The position returned by tell(), the position given to setpos() and
the position of marks are all compatible and have nothing to do with
the actual position in the file.
The close() method is called automatically when the class instance
is destroyed.
Writing AIFF files:
f = aifc.open(file, 'w')
where file is either the name of a file or an open file pointer.
The open file pointer must have methods write(), tell(), seek(), and
close().
This returns an instance of a class with the following public methods:
aiff() -- create an AIFF file (AIFF-C default)
aifc() -- create an AIFF-C file
setnchannels(n) -- set the number of channels
setsampwidth(n) -- set the sample width
setframerate(n) -- set the frame rate
setnframes(n) -- set the number of frames
setcomptype(type, name)
-- set the compression type and the
human-readable compression type
setparams(tuple)
-- set all parameters at once
setmark(id, pos, name)
-- add specified mark to the list of marks
tell() -- return current position in output file (useful
in combination with setmark())
writeframesraw(data)
-- write audio frames without pathing up the
file header
writeframes(data)
-- write audio frames and patch up the file header
close() -- patch up the file header and close the
output file
You should set the parameters before the first writeframesraw or
writeframes. The total number of frames does not need to be set,
but when it is set to the correct value, the header does not have to
be patched up.
It is best to first set all parameters, perhaps possibly the
compression type, and then write audio frames using writeframesraw.
When all frames have been written, either call writeframes(b'') or
close() to patch up the sizes in the header.
Marks can be added anytime. If there are any marks, you must call
close() after all frames have been written.
The close() method is called automatically when the class instance
is destroyed.
When a file is opened with the extension '.aiff', an AIFF file is
written, otherwise an AIFF-C file is written. This default can be
changed by calling aiff() or aifc() before the first writeframes or
writeframesraw.
