[clang-format]:Feature Request Add option to disable space before braces

[JM-FRANK]

Description

Clang-Format currently enforces a space before opening braces { for code blocks (functions, control statements, etc.), generating:

void function() { ... }
if (condition) { ... }

Request: Introduce a new configuration option (e.g., SpaceBeforeBrace) to allow disabling this space, achieving:

void function(){ ... }
if (condition){ ... }

Why This Matters

Code Style Compliance: Many projects (especially in embedded systems or legacy codebases) mandate brace styles without preceding spaces.
Consistency: Users should have full control over whitespace rules to match team/company guidelines.
Existing Limitations: Current options like BreakBeforeBraces control line breaks but not spaces.

Proposed Solution

Add a configuration option such as:

SpaceBeforeBrace: None | Always (default)

Examples:

    SpaceBeforeBrace: None → void f(){ ... }

    SpaceBeforeBrace: Always (default) → void f() { ... }

Existing options cannot achieve this:

BreakBeforeBraces: Controls line breaks, not spaces.

SpaceBeforeCpp11BracedList: Affects initialization lists only.

SpacesInParensOptions: Irrelevant to brace positioning.

Example Configuration & Output

Desired .clang-format:

BasedOnStyle: LLVM
SpaceBeforeBrace: None
BreakBeforeBraces: Attach

Formatted Code:

void example(){  // No space before {
    if (x > 0){  // No space here either
        doSomething();
    }
}

This feature would significantly enhance Clang-Format’s flexibility. Thank you for considering this request!
