## Package README (untrusted upstream documentation)
# Analyzer for Dart

This package provides a low-level _library_ that performs static analysis
of Dart code. It is useful for tool
integration and embedding.

End-users should use the [dartanalyzer][analyzercli] command-line tool
to analyze their Dart code.

Integrators that want to add Dart support to their editor
should use the _Dart Analysis Server_.
The [Analysis Server API Specification][serverapi] is available.
If you are adding Dart support to an editor or IDE, please let us know
by emailing our [list][].

## Configuring the analyzer

Both `dartanalyzer` and Dart Analysis Server can be configured with an
`analysis_options.yaml` file (using an `.analysis_options` file is deprecated).
This YAML file can control which files and paths are analyzed,
which lints are applied, and more.

If you are embedding the analyzer library in your project, you are responsible
for finding the analysis options file, parsing it, and configuring the analyzer.

The analysis options file should live at the root of your project (for example,
next to your `pubspec.yaml`). Different embedders of analyzer, such as
`dartanalyzer` or Dart Analysis Server, may choose to find the file in various
different ways. Consult their documentation to learn more.

Here is an example file that instructs the analyzer to ignore two files:

```yaml
analyzer:
  exclude:
    - test/_data/p4/lib/lib1.dart
    - test/_data/p5/p5.dart
    - test/_data/bad*.dart
    - test/_brokendata/**
```

Note that you can use globs, as defined by the [glob package][glob].

Here is an example file that enables the analyzer's [strong mode][strongmode]:

```yaml
analyzer:
  strong-mode: true
```

Here is an example file that enables two lint rules:

```yaml
linter:
  rules:
    - camel_case_types
    - empty_constructor_bodies
```

Check out all the available [Dart lint rules][lintrules].

You can combine the `analyzer` section and the `linter` section into a single
configuration. Here is an example:

```yaml
analyzer:
  exclude:
    - test/_data/p4/lib/lib1.dart
linter:
  rules:
    - camel_case_types
```

## Who uses this library?

Many tools embed this library, such as:

* [dartfmt] - a formatter for Dart code
* [dartdoc] - a documentation generator for Dart code
* [Dart Analysis Server][analysis_sever] - a stateful server that supports IDEs and editors

## Support

Post issues and feature requests at https://github.com/dart-lang/sdk/issues

Questions and discussions are welcome at the
[Dart Analyzer Discussion Group][list].

## Background

The APIs in this package are, quite frankly, a mess at the moment. They were
originally machine generated by a translator and were based on an earlier Java
implementation. Several of the API's still look like their Java predecessors
(or worse) rather than clean Dart API's.

In addition, there is currently no clean distinction between public and internal
APIs. We plan to address this issue but doing so will, unfortunately,
require a large number of breaking changes. We will try to minimize the pain
this causes for our clients, but some pain is inevitable.

## Changelog
## 0.30.0-alpha.0
* Changed the API for creating BazelWorkspace.  It should now be constructed using BazelWorkspace.find().  Note that this might return `null` in the event that the given path is not part of a BazelWorkspace.
* Added an AST structure to support asserts in constructor initializers (AssertInitializer).  AstVisitor classes must now implement visitAssertInitializer().
* Changed the API for creating PartOfDirective.  It now accepts a StringLiteral URI, to accommodate "part of" declarations with a URI string rather than a library name.
* Removed AST constructors.  AST nodes should now be created using `astFactory`, located in `package:analyzer/dart/ast/standard_ast_factory.dart`.

## 0.29.0-alpha.0
* Removed `Element.docRange`.

## 0.28.2-alpha.0
* Corresponds with the analyzer/server in the `1.20.0-dev.1.0 ` SDK.

## 0.28.0-alpha.2
* Fixed PubSummaryManager linking when a listed package does not have the unlinked bundle.

## 0.27.4-alpha.19
* Added support for running the dev compiler in the browser.

## 0.27.4-alpha.18
* Support for references to operators in doc comments (#26929).

## 0.27.4-alpha.17
* Support for trailing commas in parameter and argument lists (#26647).
* Strong mode breaking change: can now infer generic type arguments from the constructor invocation arguments (#25220).

## 0.27.4-alpha.16
* (Internal) Corresponds with the analyzer/server in the `1.18.0-dev.4.0` SDK.

## 0.27.4-alpha.9
* Restore EmbedderUriResolver API.

## 0.27.4-alpha.8
* Ignore processing performance improvements.
* EmbedderUriResolver API updates.

  method AnalysisEngine.processRequiredPlugins().
* Removed the old task model and code that supported it. None of the removed code was intended to be public API, but
  might be in use anyway.
* Removed previously deprecated API's (marked with the @deprecated annotation).
