This regresses the test case of `zig fmt` deleting empty line comments.
Two open questions here:
* What should the rules be about deleting empty line comments?
It makes sense usually, but for array initization, empty line
comments cause a line break, affecting the row/column alignment.
Perhaps we should therefore respect all empty line comments?
Or should we special case array initializations?
* If we decide to special case some kinds of line comments to respect
them (which is status quo!), how should that be implemented?
I modified this test case to expect different results.
Now, the trailing comma on a list of struct fields is the only deciding
factor, not whether or not the field init expressions contain a newline.
Achieve this by reducing the amount of special casing to handle EOF so
that the already correct logic for normal comments does not need to be
duplicated.
After #35 is implemented,
we should be able to recover from this *at any indentation level*,
reporting a parse error and yet also parsing all the decls even
inside structs. Until then, I don't want to add any hacks to make
this work.
I don't understand the idea here of this kind of recovery. If we
want to resurrect this test case we need some comments on it to explain
the purpose, example use cases, expected behavior, etc.
* Added support for passing write file args as build options
* Fix missing fmtEscapes and unused format
* Actually fixed now, must be formatted
* remove addPathBuildOption
The z/Z format specifiers were merged last October (4 months ago). They were then deprecated in January (just over a month ago). This PR removes them altogether.
All stage2 tests are passing again in this branch.
Remaining checklist for this branch:
* get the rest of the zig fmt test cases passing
- re-enable the translate-c test case that is blocking on this
* implement the 2 `@panic(TODO)`'s in parse.zig
* use fn_proto not fn_decl for extern function declarations
Allowing same line doc comments causes some ambiguity as to how
generated docs should represent the case in which both same line
and preceding line doc comments are present:
/// preceding line
const foobar = 42; /// same line
Furthermore disallowing these makes things simpler as there is now only
one way to add a doc comment to a decl or struct field.
Using this in its current state would be a bug as it could cause line
comments to be deleted or a `// zig fmt: (on|off)` directive to be
missed.
Removing it doesn't currently cause any test failures, if a reason for
its continued existence is discovered in the future another solution
will have to be found.
This type is not widely applicable enough to be a public part of the
public interface of the std.
The current implementation in only fully utilized by the zig fmt
implementation, which could benefit by even tighter integration as
will be demonstrated in the next commit. Therefore, move the current
io.AutoIndentingStream to lib/std/zig/render.zig.
The C backend of the self hosted compiler also use this type currently,
but it does not require anywhere near its full complexity. Therefore,
implement a greatly simplified version of this interface in
src/codegen/c.zig.
