This adjusts the code to run identically under python 2 and python 3.
We would previously fail to digest the content in Python 3 as the `map`
is not equivalent. This now results in the same encoding as Python 2.
This changes the hash from the Python `hash` function to SHA1. Python 3
adopted SIP as the hashing algorithm which changed the hash results. We
could no longer use a different python interpreter across the builds. A
stable hashing algorithm allows easier migration.
Like switch cases, a catch clause may now include a comma-
separated list of patterns. The body will be executed if any
one of those patterns is matched.
This patch replaces `CatchStmt` with `CaseStmt` as the children
of `DoCatchStmt` in the AST. This necessitates a number of changes
throughout the compiler, including:
- Parser & libsyntax support for the new syntax and AST structure
- Typechecking of multi-pattern catches, including those which
contain bindings.
- SILGen support
- Code completion updates
- Profiler updates
- Name lookup changes
The `@transpose(of:)` attribute registers a function as a transpose of another
function. This patch adds the `@transpose(of:)` attribute definition, syntax,
parsing, and printing.
Resolves TF-827.
Todos:
- Type-checking (TF-830, TF-1060).
- Enable serialization (TF-838).
- Use module-qualified names instead of custom qualified name syntax/parsing
(TF-1066).
The `@derivative(of:)` attribute registers a function as a derivative of another
function. This patch adds the `@derivative(of:)` attribute definition, syntax,
parsing, and printing.
Resolves TF-826.
Todos:
- Type-checking (TF-829).
- Serialization (TF-837).
This PR introduces `@differentiable` attribute to mark functions as differentiable. This PR only contains changes related to parsing the attribute. Type checking and other changes will be added in subsequent patches.
See https://github.com/apple/swift/pull/27506/files#diff-f3216f4188fd5ed34e1007e5a9c2490f for examples and tests for the new attribute.
The node descriptions are printed as dedented multi-line strings when
the corresponding files are being generated in SwiftSyntax. To do this,
however, the strings need to be multi-line to begin with and not have
the line break escaped.
To represent a type with code completion.
type? '.'? <code-completion-token>
This is "parser only" node which is not exposed to SwiftSyntax.
Using this, defer to set the parsed type to code-completion callbacks.
