This came up in issue #11204:
When emitting a warning for a type unification error,
the compiler overly simplifies the formatting of types
when these are maps or unions of maps.
To address this, we recursively check for maps inside
of a union type when comparing it to another map-like type.
- Support negative insertion indices
- Give a clear RuntimeError, rather than a baffling CondClauseError, when you ask for an insertion point that matches the last element of your range
This allows the formatter plugins to format content
based on whether it's a file or a sigil being formatted.
The modifiers could be used for additional options.
We also extend Mix.Tasks.Compiler.Diagnostic
to include {line, column} as possible position.
We also explicitly document the behaviour of
line=0, which is equivalent to unknown line.
Elixir was already setting the line to zero in
multiple occasions prior to this patch, so this
patch makes it official and we stop returning `nil`
for said cases.
This reverts commit 213cba2baa.
Including columns by default make Ecto test suite
consistently 10% slower and that's likely to replicate
across the board.
This changes the default for Code.string_to_quoted/2
and friends, so it may break tests matching explicitly
on the output, but the functionality wise the AST should
still be the same. The reason why it is important to make
this change is to provide better error messages throughout
Elixir.
In order to support calendars which can change
era any time during the calendar year, the callback
Calendar.year_of_era/1 is changed to Calendar.year_of_era/3.
Since Calendar.ISO.year_of_era/1 is a public function,
default arguments for month and day are set if
year_of_era/1 is called to allow compatibility with
any existing code that relies upon this function.
Task.Supervisor.async/* would copy the MFA to the supervisor
process. async_stream/* would additionally copy the value to
the stream coordinator. This commit makes it so those copies
are no longer necessary. The only unnecessary copy is in
Task.Supervisor.start_child/2 which we can't address due to
backwards compatibility.
This improves unclear errors that result in the case where a
custom protocol is passed as the inspect_fun option, and that
protocol is not implemented for some of the types being inspected.
Missing struct implementations are a pathological case here, because
when trying to inspect them as maps, a seemingly unrelated error
message about a missing atom implementation will be reported, while
trying to inspect the value of the :__struct__ field
