Code formatting helpers for the x2c compiler.

Functions

Compiler

Compiler.code_pretty_string

char *Compiler.code_pretty_string(Compiler cc, List code, String output_file)

Returns a canonical formatted C String for an emitted token List. Token order and code are unchanged. Braces indent by two spaces, semicolons break lines only outside parentheses, and preprocessor tokens occupy their own lines. An empty List returns the empty String. Emitted src-at markers carry existing compiler origin IDs; zero restores output_file at its physical line.

Raises: <size-limit> or <alloc-fail> while materializing the result.

Design notes

Converts emitted token Lists to pretty or compact C text without changing token order. Parenthesis depth suppresses statement breaks within expressions, and Buffer materializes the final String.
