# Changelog
All notable changes to this project will be documented in this file.
## [Unreleased]
## [0.11.1] - 2021-01-18
### Added
- Add `Chars::{box_drawing, ascii}` functions, the latter supporting a rustc-style of
output that only uses ASCII characters (not above U+007F) for use cases that do not allow
for box drawing characters, e.g. terminals that do not support them.
### Changed
- `Diagnostic::with_labels` and `Diagnostic::with_notes` now append additional
labels rather tan overwriting them, meaning that the documentation and behaviour match
more closely. The behaviour will only differ if you call the same builder methods
multiple times. If you call every builder method once only, nothing should change.
- `config::Chars::snippet_start` is now a String instead of a single `char`.
## [0.11.0] - 2020-11-30
There is now a [code of conduct](https://github.com/brendanzab/codespan/blob/master/CODE_OF_CONDUCT.md)
Some versions were skipped to sync up with the `codespan-lsp` crate. The release
process has been changed so this should not happen again.
### Added
- If a label spans over multiple lines, not all lines are rendered.
The number of lines rendered at beginning and end is configurable separately.
- There is now a custom error type.
- There now is a medium rendering mode that is like the short rendering mode
but also shows notes from the diagnostic.
- `PartialEq` and `Eq` implementations for the `diagnostic::{Diagnostic, Label, Severity}` types.
### Changed
- All errors now use the error type `codespan_reporting::file::Error`.
This type also replaces the custom error type for `codespan-lsp`.
### Fixed
- Empty error codes are not rendered.
- The locus ("location of the diagnostic") is now computed so it is always at the first
primary label, or at the first secondary label if no primary labels are available.
- All `unwrap`s outside of tests and examples have been removed.
- Some internal improvements, including various code style improvements by using Clippy.
- Improved documentation, also mentioning how the ordering of labels is handled.
## [0.9.5] - 2020-06-24
### Changed
- Sections of source code that are marked with primary labels are now rendered
using the primary highlight color.
- Tab stops are now rendered properly.
We used to just render `\t` characters in source snippets with the same
number of spaces.
<details>
<summary>Example</summary>
For example, when rendering with a tab width of `3` we
would print:
```text
warning: tab test
┌─ tab_columns:1:2
│
1 │ hello
│ ^^^^^
2 │ ∙ hello
│ ^^^^^
3 │ ∙∙ hello
│ ^^^^^
4 │ ∙∙∙ hello
│ ^^^^^
5 │ ∙∙∙∙ hello
│ ^^^^^
6 │ ∙∙∙∙∙ hello
│ ^^^^^
7 │ ∙∙∙∙∙∙ hello
│ ^^^^^
```
Now we properly take into account the column of the tab character:
```text
warning: tab test
┌─ tab_columns:1:2
│
1 │ hello
│ ^^^^^
2 │ ∙ hello
│ ^^^^^
3 │ ∙∙ hello
│ ^^^^^
4 │ ∙∙∙ hello
│ ^^^^^
5 │ ∙∙∙∙ hello
│ ^^^^^
6 │ ∙∙∙∙∙ hello
│ ^^^^^
7 │ ∙∙∙∙∙∙ hello
│ ^^^^^
```
</details>
## [0.9.4] - 2020-05-18
### Changed
- We have made the caret rendering easier to read when there are multiple
labels on the same line. We also avoid printing trailing borders on the
final source source snippet if no notes are present.
<details>
<summary>Example</summary>
Instead of this:
```text
┌─ one_line.rs:3:5
│
3 │ v.push(v.pop().unwrap());
│ - first borrow later used by call
│ ---- first mutable borrow occurs here
│ ^ second mutable borrow occurs here
│
```
…we now render the following:
```text
┌─ one_line.rs:3:5
│
3 │ v.push(v.pop().unwrap());
│ - ---- ^ second mutable borrow occurs here
│ │ │
│ │ first mutable borrow occurs here
│ first borrow later used by call
```
</details>
### Fixed
- Diagnostic rendering no longer panics if label ranges are between UTF-8
character boundaries.
## [0.9.3] - 2020-04-29
### Changed
- Some panics were fixed when invalid unicode boundaries are supplied.
- Labels that marked the same span were originally rendered in reverse order.
This was a mistake! We've now fixed this.
<details>
<summary>Example</summary>
For example, this diagnostic:
```text
┌─ same_range:1:7
│
1 │ ::S { }
│ - Expected '('
│ ^ Unexpected '{'
│
```
…will now be rendered as:
```text
┌─ same_range:1:7
│
1 │ ::S { }
│ ^ Unexpected '{'
│ - Expected '('
│
```
</details>
- We've reduced the prominence of the 'locus' on source snippets by
simplifying the border and reducing the spacing around it. This is to help
focus attention on the underlined source snippet and error messages, rather
than the location, which should be a secondary focus.
<details>
<summary>Example</summary>
For example we originally rendered this:
```text
error: unknown builtin: `NATRAL`
┌── Data/Nat.fun:7:13 ───
│
7 │ {-# BUILTIN NATRAL Nat #-}
│ ^^^^^^ unknown builtin
│
= there is a builtin with a similar name: `NATURAL`
```
…and now we render this:
```text
error: unknown builtin: `NATRAL`
┌─ Data/Nat.fun:7:13
│
7 │ {-# BUILTIN NATRAL Nat #-}
│ ^^^^^^ unknown builtin
│
= there is a builtin with a similar name: `NATURAL`
```
</details>
## [0.9.2] - 2020-03-29
### Changed
- Render overlapping multiline marks on the same lines of source code.
<details>
<summary>Example</summary>
For example:
```text
error[E0308]: match arms have incompatible types
┌── codespan/src/file.rs:1:9 ───
│
1 │ ╭ match line_index.compare(self.last_line_index()) {
2 │ │ Ordering::Less => Ok(self.line_starts()[line_index.to_usize()]),
3 │ │ Ordering::Equal => Ok(self.source_span().end()),
4 │ │ Ordering::Greater => LineIndexOutOfBoundsError {
5 │ │ given: line_index,
6 │ │ max: self.last_line_index(),
7 │ │ },
8 │ │ }
│ ╰─────────' `match` arms have incompatible types
·
2 │ Ordering::Less => Ok(self.line_starts()[line_index.to_usize()]),
│ --------------------------------------------- this is found to be of type `Result<ByteIndex, LineIndexOutOfBoundsError>`
3 │ Ordering::Equal => Ok(self.source_span().end()),
│ ---------------------------- this is found to be of type `Result<ByteIndex, LineIndexOutOfBoundsError>`
4 │ Ordering::Greater => LineIndexOutOfBoundsError {
│ ╭──────────────────────────────────^
5 │ │ given: line_index,
6 │ │ max: self.last_line_index(),
7 │ │ },
│ ╰─────────────^ expected enum `Result`, found struct `LineIndexOutOfBoundsError`
│
= expected type `Result<ByteIndex, LineIndexOutOfBoundsError>`
found type `LineIndexOutOfBoundsError`
```
…is now rendered as:
```text
error[E0308]: match arms have incompatible types
┌── codespan/src/file.rs:1:9 ───
│
1 │ ╭ match line_index.compare(self.last_line_index()) {
2 │ │ Ordering::Less => Ok(self.line_starts()[line_index.to_usize()]),
│ │ --------------------------------------------- this is found to be of type `Result<ByteIndex, LineIndexOutOfBoundsError>`
3 │ │ Ordering::Equal => Ok(self.source_span().end()),
│ │ ---------------------------- this is found to be of type `Result<ByteIndex, LineIndexOutOfBoundsError>`
4 │ │ Ordering::Greater => LineIndexOutOfBoundsError {
│ ╭─│──────────────────────────────────^
5 │ │ │ given: line_index,
6 │ │ │ max: self.last_line_index(),
7 │ │ │ },
│ ╰─│─────────────^ expected enum `Result`, found struct `LineIndexOutOfBoundsError`
8 │ │ }
│ ╰─────────' `match` arms have incompatible types
│
= expected type `Result<ByteIndex, LineIndexOutOfBoundsError>`
found type `LineIndexOutOfBoundsError`
```
</details>
## [0.9.1] - 2020-03-23
### Added
- `codespan_reporting::diagnostic::Diagnostic` now implements `Debug`.
### Changed
- Single-line labels are now rendered together, under the same source line.
<details>
<summary>Example</summary>
For example:
```text
┌── one_line.rs:3:5 ───
│
3 │ v.push(v.pop().unwrap());
│ - first borrow later used by call
·
3 │ v.push(v.pop().unwrap());
│ ---- first mutable borrow occurs here
·
3 │ v.push(v.pop().unwrap());
│ ^ second mutable borrow occurs here
│
```
…is now rendered as:
```text
┌── one_line.rs:3:5 ───
│
3 │ v.push(v.pop().unwrap());
│ - first borrow later used by call
│ ---- first mutable borrow occurs here
│ ^ second mutable borrow occurs here
│
```
</details>
## [0.9.0] - 2020-03-11
### Added
- The `codespan_reporting::files` module was added as a way to decouple
`codespan_reporting` from `codespan`.
- `codespan_reporting::files::Files` allows users to implement custom file
databases that work with `codespan_reporting`. This should make it
easier to integrate with libraries like Salsa, and also makes it less
invasive to use `codespan_reporting` on existing projects.
- `codespan_reporting::files::SimpleFile` is a simple implementation of
`codespan_reporting::files::Files` where only a single file is needed.
- `codespan_reporting::files::SimpleFiles` is a simple implementation of
`codespan_reporting::files::Files` where multiple files are needed.
### Changed
- The `codespan_reporting::diagnostic` module has been greatly revamped,
making the builder API format more nicely with rustfmt, and allowing for
multiple primary labels.
- The output of `codespan_reporting::term::emit` was improved,
with the following changes:
- labels on consecutive lines no longer render breaks between them
- source lines are rendered when there is only one line between labels
- the inner gutter of code snippets is now aligned consistently
- the outer gutter of consecutive code snippets are now aligned consistently
- `codespan_reporting::term::emit` now takes writers as a trait object (rather
than using static dispatch) in order to reduce coda bloat and improve
compile times.
- The field names in `codespan_reporting::term::Chars` were tweaked for
consistency.
### Removed
- `codespan_reporting` no longer depends on `codespan`.
Note that `codespan` can _still_ be used with `codespan_reporting`,
as `codespan::Files` now implements `codespan_reporting::files::Files`.
