A cli tool that injects a comma at the end of parameter and argument lists

dart-comma-injector

A cli tool to inject commas at the end of parameter and argument lists, because it looks so much better with a comma at the end

Why

The default dart formatter does some weird things with long parameter lists

This

void func(String a, String b, String c, String d, String e, String f, String g, String h) {}

Becomes this after running dart format

void func(String a, String b, String c, String d, String e, String f, String g,
    String h) {}

Which is subjectively ugly

One way to improve this, is to put a comma at the end of the parameter list, which will format the function like so after format

void func(
    String a, 
    String b, 
    String c, 
    String d, 
    String e, 
    String f, 
    String g,
    String h,
) {}

Because I'm lazy, this cli tool (which is designed to be run from a IDE extension), will inject a comma at the end of the list, so the formatter outputs prettier results

Installation / Usage

CLI

dart pub global activate dart_comma_injector

# Call with line/column
dart_comma_injector ./path/to/file.dart --line 45 --column 8

# Or via offset
dart_comma_injector ./path/to/file.dart --offset 115

vscode

There is a .vsix file within the vscode directory that can be downloaded and installed manually. TBD on if I publish it...
