# Changelog for Elixir v1.16

## Code snippets in diagnostics

Elixir v1.15 introduced a new compiler diagnostic format and the ability to \ 
print multiple error diagnostics per compilation (in addition to multiple \ 
warnings).

With Elixir v1.16, we also include code snippets in exceptions and diagnostics \ 
raised by the compiler. For example, a syntax error now includes a pointer to \ 
where the error happened:

```
** (SyntaxError) invalid syntax found on lib/my_app.ex:1:17:
    error: syntax error before: '*'
    │
  1 │ [1, 2, 3, 4, 5, *]
    │                 ^
    │
    └─ lib/my_app.ex:1:17
```

For mismatched delimiters, it now shows both delimiters:

```
** (MismatchedDelimiterError) mismatched delimiter found on lib/my_app.ex:1:18:
    error: unexpected token: )
    │
  1 │ [1, 2, 3, 4, 5, 6)
    │ │                └ mismatched closing delimiter (expected "]")
    │ └ unclosed delimiter
    │
    └─ lib/my_app.ex:1:18
```

For unclosed delimiters, it now shows where the unclosed delimiter starts:

```
** (TokenMissingError) token missing on lib/my_app:8:23:
    error: missing terminator: )
    │
  1 │ my_numbers = (1, 2, 3, 4, 5, 6
    │              └ unclosed delimiter
 ...
  8 │ IO.inspect(my_numbers)
    │                       └ missing closing delimiter (expected ")")
    │
    └─ lib/my_app:8:23
```

Errors and warnings diagnostics also include code snippets. When possible, we \ 
will show precise spans, such as on undefined variables:

```
  error: undefined variable "unknown_var"
  │
5 │     a - unknown_var
  │         ^^^^^^^^^^^
  │
  └─ lib/sample.ex:5:9: Sample.foo/1
```

Otherwise the whole line is underlined:

```
error: function names should start with lowercase characters or underscore, \ 
invalid name CamelCase
  │
3 │   def CamelCase do
  │   ^^^^^^^^^^^^^^^^
  │
  └─ lib/sample.ex:3
```

A huge thank you to Vinícius Müller for working on the new diagnostics.

## Revamped documentation

Elixir's Getting Started guides have been made part of the Elixir repository and \ 
incorporated into ExDoc. This was an opportunity to revisit and unify all \ 
official guides and references.

We have also incorporated and extended the work on [Understanding Code Smells in \ 
Elixir Functional \ 
Language](https://github.com/lucasvegi/Elixir-Code-Smells/blob/main/etc/2023-emse-code-smells-elixir.pdf), \ 
by Lucas Vegi and Marco Tulio Valente, from \ 
[ASERG/DCC/UFMG](http://aserg.labsoft.dcc.ufmg.br/), into the official document \ 
in the form of anti-patterns. The anti-patterns are divided into four \ 
categories: code-related, design-related, process-related, and meta-programming. \ 
Our goal is to give all developers examples of potential anti-patterns, with \ 
context and examples on how to improve their codebases.

Another [ExDoc](https://github.com/elixir-lang/ex_doc) feature we have \ 
incorporated in this release is the addition of cheatsheets, starting with [a \ 
cheatsheet for the Enum module](https://hexdocs.pm/elixir/main/enum-cheat.html). \ 
If you would like to contribute future cheatsheets to Elixir itself, feel free \ 
to start a discussion with an issue.

Finally, we have started enriching our documentation with \ 
[Mermaid.js](https://mermaid.js.org/) diagrams. You can find examples in the \ 
[GenServer](https://hexdocs.pm/elixir/main/GenServer.html) and \ 
[Supervisor](https://hexdocs.pm/elixir/main/Supervisor.html) docs.

  * [Code.Fragment] Fix crash in `Code.Fragment.surround_context/2` when \ 
matching on `->`

  * [Kernel] Warn when a private function or macro uses `unquote/1` and the \ 
function/macro itself is unused

in their definition
  * [Kernel.ParallelCompiler] Consider a module has been defined in \

### 3. Soft deprecations (no warnings emitted)

#### Elixir

keeping the options as last argument, as in `File.stream!(file, line_or_bytes, \ 
options)`

with a negative step instead
  * [Enum] Deprecate passing a range with negative step on `Enum.slice/2`, give \ 
`first..last//1` instead
  * [Kernel] `~R/.../` is deprecated in favor of `~r/.../`. This is because \ 
`~R/.../` still allowed escape codes, which did not fit the definition of \ 
uppercase sigils
  * [String] Deprecate passing a range with negative step on `String.slice/2`, \ 
give `first..last//1` instead

#### ExUnit

  * [ExUnit.Formatter] Deprecate `format_time/2`, use `format_times/1` instead
