Suggestion

When the formatting option for the opening brace on newline for control blocks is true, it would make sense to have the else on it's online as well.

Use Cases

Using typescript-formatter with VS Code, and from command line.

Examples

My tsfmt.json is:

{
    "baseIndentSize": 0,
    "indentSize": 4,
    "tabSize": 4,
    "indentStyle": 2,
    "newLineCharacter": "\n",
    "convertTabsToSpaces": true,
    "insertSpaceAfterCommaDelimiter": true,
    "insertSpaceAfterSemicolonInForStatements": true,
    "insertSpaceBeforeAndAfterBinaryOperators": true,
    "insertSpaceAfterConstructor": false,
    "insertSpaceAfterKeywordsInControlFlowStatements": true,
    "insertSpaceAfterFunctionKeywordForAnonymousFunctions": false,
    "insertSpaceAfterOpeningAndBeforeClosingNonemptyParenthesis": false,
    "insertSpaceAfterOpeningAndBeforeClosingNonemptyBrackets": false,
    "insertSpaceAfterOpeningAndBeforeClosingNonemptyBraces": true,
    "insertSpaceAfterOpeningAndBeforeClosingTemplateStringBraces": false,
    "insertSpaceAfterOpeningAndBeforeClosingJsxExpressionBraces": false,
    "insertSpaceAfterTypeAssertion": false,
    "insertSpaceBeforeFunctionParenthesis": false,
    "insertSpaceBeforeTypeAnnotation": false,
    "placeOpenBraceOnNewLineForFunctions": true,
    "placeOpenBraceOnNewLineForControlBlocks": true
}

I get results like this:

if(condition)
{
     console.log('condition true');
} else if(otherCondition)
{
     console.log('other condition is true');
} else 
{
     console.log('condition not true');
}

For people using "placeOpenBraceOnNewLineForControlBlocks": true, the expected behaviour (IMHO) would be:

if(condition)
{
     console.log('condition true');
} 
else if(otherCondition)
{
     console.log('other condition is true');
} 
else 
{
     console.log('condition not true');
}

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

Commencez par localiser les points d’entrée du formateur utilisés pour le formatage de TypeScript dans VS Code et dans le typescript-formatter en ligne de commande, puis suivez le traitement des accolades des blocs de contrôle. Comparez les exemples actuels et attendus ; c’est terminé lorsque le style de saut de ligne configuré place else sur sa propre ligne sans modifier les autres comportements de formatage.
