Fixes#11353
The renderer treats comments and doc comments differently since doc
comments are parsed into the Ast. This commit adds a check after getting
the text for the doc comment and trims whitespace at the end before
rendering.
The `a = 0,` in the test is here to avoid a ParseError while parsing the
test.
* Fixes#8810.
* Prevent a single-line container declaration if it contains a comment
or multiline string.
* If a container declaration cannot be single-line, ensure container
fields are rendered with a trailing comma.
* If `Space.comma` is passed to `renderExpressionComma` or
`renderTokenComma`, and there already exists a comma in the source,
then render one comma instead of two.
* Remove the builtins `@addWithSaturation`, `@subWithSaturation`,
`@mulWithSaturation`, and `@shlWithSaturation` now that we have
first-class syntax for saturating arithmetic.
* langref: Clarify the behavior of `@shlExact`.
* Ast: rename `bit_shift_left` to `shl` and `bit_shift_right` to `shr`
for consistency.
* Air: rename to include underscore separator with consistency with
the rest of the ops.
* Air: add shl_exact instruction
* Use non-extended tags for saturating arithmetic, to keep it
simple so that all the arithmetic operations can be done the same
way.
- Sema: unify analyzeArithmetic with analyzeSatArithmetic
- implement comptime `+|`, `-|`, and `*|`
- allow float operands to saturating arithmetic
* `<<|` allows any integer type for the RHS.
* C backend: fix rebase conflicts
* LLVM backend: reduce the amount of branching for arithmetic ops
* zig.h: fix magic number not matching actual size of C integer types
- adds initial support for the operators +|, -|, *|, <<|, +|=, -|=, *|=, <<|=
- uses operators in addition to builtins in behavior test
- adds binOpExt() and assignBinOpExt() to AstGen.zig. these need to be audited
We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.
Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.
rowSize used to return null if all the elements were placed on the same
line as the right brace, making the rendering logic skip the whole set
of elements.
Given the usage of rowSize let's just drop the null and always return
the number of elements.
Fixes#8423
Bring this in line with how variable declarations are handled.
Open a new indentation level for the initialization expression to handle
nested expressions like blocks.
Closes#7618
The main realization here was that getting rid of the early returns
in renderWhile() and rewriting the logic into a mostly unified execution
path took things from ~200 lines to ~100 lines and improved consistency
by deduplicating code.
Also add several test cases and fix a few issues along the way:
Fixes https://github.com/ziglang/zig/issues/6114
Fixes https://github.com/ziglang/zig/issues/8022
Add failing testcase to reproduce issue 8088
Tidy up renderWhile(), factoring out renderWhilePayload()
Ensure correct newline is used before 'then' token in while/for/if
Handle indents for 'if' inside 'for' or 'while'
Stop special-casing 'if' compared to 'for' and 'while'
The modification to the grammar in the comment is in line with the
grammar in the zig-spec repo.
Note: checking if the previous token is a colon is insufficent to tell
if a block has a label, the identifier must be checked for as well. This
can be seen in sentinel terminated slicing: `foo[0..1:{}]`
Currently `// zig fmt: off` does not work as there are two spaces
after the `//` instead of one. This can cause confusion, so allow
arbitrary whitespace before the `zig fmt: (off|on)` in the comment but
trim this whitespace to the canonical single space in the output.
