fn (mut g Gen) gen() string

gen generates C source from the transformed AST files.

fn (mut g Gen) set_cache_bundle_name(name string)

set_cache_bundle_name sets the cache bundle label used for emitting a deterministic cache-init function (e.g. __v2_cached_init_builtin).

fn (mut g Gen) set_cached_init_calls(calls []string)

fn (mut g Gen) set_emit_modules(modules []string)

set_emit_modules limits code emission to the provided module names. Type declarations and forward declarations are still emitted for all modules.

fn (mut g Gen) set_export_const_symbols(enable bool)

set_export_const_symbols controls whether emitted module const macros also get exported as linkable global symbols.

fn (mut g Gen) set_used_fn_keys(used map[string]bool)
