* Add more tests for diagnostic_source
* Use Borrow::borrow instead of AsRef
AsRef is not reflexive, meaning that it is not implemented as &T for all
T. Borrow is though, so we use that to make sure that we always get a
reference that is correct, even in the presence of smart pointers.
* Fixed/formatted all intradoc links. Various other small doc fixes/typography/etc.
* Clarified semantic similarity with anyhow/eyre types/macros.
* Removed unused MietteError::SetPrinterFailure.
* README now generaed from lib.rs via `cargo readme`.
* More doc fixes, made ErrorHook type public.
* Indentation (docs).
Techically there was a hidden undocumented `context` method. But it was
just copied from the `eyre` and there is no evidence that it was used by
any user in miette (the method was an alias for `.handler()`).
Fixes#108
Fixes#106
While fixing the bug I've also extended the handler to print not just
where label starts but also where label ends.
Also implements #97, but for narratabble handler only.
This adds dependency on `unicode-width`, but it was already in the
dependency chain (`textwidth` depends on it). Although, previously it
was only for `"fancy"` feature, now it always required since narratable
handler is supported without `"fancy"`.
BREAKING CHANGE: The default fancy reporter is no longer available unless you enable the "fancy" feature. This also means you will not be pulling in a bunch of deps if you are using miette for a library
Fixes: https://github.com/zkat/miette/issues/25
This PR overhauls the toplevel/main experience for `miette`. It adds a new `Report` type based on `eyre::Report` and overhauls various types to fit into this model, as well as prepare for some [future changes in Rust](https://github.com/nrc/rfcs/pull/1) that will make it possible to integrate `miette` directly with crates like `eyre` instead of having to use this specific `Report`.
As such, this PR is a major breaking change, especially for anyone using `DiagnosticReport` and company.
BREAKING CHANGES:
* `DiagnosticReport` is now just `Report`, and is a different, `eyre::Report`-like type.
* `DiagnosticResult` is now just `Result`.
* `.into_diagnostic()` now just transforms the error into a `Report`.
* `DiagnosticReportPrinter` has been replaced with `ReportHandler`
* `set_printer` has been replaced by `set_hook`
* `code` is now optional.
* `.into_diagnostic()` no longer takes a `code` argument.
* `#[diagnostic]` is now optional when deriving `Diagnostic`.
