better_imports 1.2.0

A better imports sorter for your .dart files.

better_imports

This Dart package provides a command-line interface (CLI) for sorting and organizing imports in Dart projects.
Users can customize the import sorting behavior using various flags and options.

Features

• default config
• using external config
• sorting all .dart files
• converting package imports to relative imports and back
• sorting specific folders
• sorting specific files
• regex-based filtering for inclusion or exclusion
• ignoring specific files
• adding comments to import types / sections
• toggling console output
• tracing/logging

Example

Before

library better_imports;
import 'dart:io';
import 'package:better_imports/lib.dart';
import 'cfg_test.dart';
import 'package:dart_style/dart_style.dart';
import '../res/sorter_fixtures.dart';
import 'package:test/test.dart';

void main() {
  final formatter = DartFormatter();
}

After (default config)

library better_imports;

// Dart Imports
import 'dart:io';

// Package Imports
import 'package:dart_style/dart_style.dart';
import 'package:test/test.dart';

// Project Imports
import 'package:better_imports/lib.dart';

// Relative Project Imports
import '../res/sorter_fixtures.dart';
import 'cfg_test.dart';

void main() {
  final formatter = DartFormatter();
}

Usage

Recommended: Native executeable

• Download the precompiled executeables OR fork the repo and compile it yourself
  • Inside your project, root directory:
  • dart compile exe .\bin\better_imports.dart
• Extract the downloaded archive / move the compiled executeable in to a folder of your choosing
  • If needed rename the executeable for your OS to better_imports
• Add the chosen folder / executeable to your PATH environment variable
  • Win: How to Add to Windows PATH Environment Variable
  • Mac: How to Set the PATH Variable in macOS
  • Linux: How to Add a Directory to Your $PATH in Linux
• Go to your project folder, root directory
• run:
  • better_imports

As a dependency (this is around 10x slower)

• Follow the usual package installation instructions
• Consider making it a dev_dependency, you won't depend on anything
• run:
  • dart pub run better_imports:better_imports
  • OR in flutter:
  • flutter pub run better_imports:better_imports

On Save Action in VSCode

• Install Run on Save extension
• Add the following config to your settings.json

"emeraldwalk.runonsave": {
    "commands": [
        {
            "match": "\\.dart$",
            "cmd": "better_imports --files ${fileBasename} -s"
        }
    ]
}

Additional information

Overriding default values

You can override default config values by adding an better_imports section to your pubspec.yaml file.
Or by providing command line arguments.

Command line argements override any other setting if provided!

For example:
Copy and paste the default config into your pubspec.yaml file.
Make sure you keep the proper indentation.

External config

If you want to use an external config file you can add a minimalistic better_imports section to your pubspec.yaml file.
For example:

better_imports:
  cfg_path: path/to/your/config/cfg.yaml

--- OR ---

Provide the --cfg CLI option.
For example: better_imports --cfg path/to/your/config/cfg.yaml
