// CODE BUILDER
// ================================================================================================

/// A builder for compiling account components, note scripts, and transaction scripts with optional
/// library dependencies.
///
/// The [`CodeBuilder`] simplifies the process of creating transaction scripts by providing:
/// - A clean API for adding multiple libraries with static or dynamic linking
/// - Automatic assembler configuration with all added libraries
/// - Debug mode support
/// - Builder pattern support for method chaining
///
/// ## Static vs Dynamic Linking
///
/// **Static Linking** (`link_static_library()` / `with_statically_linked_library()`):
/// - Use when you control and know the library code
/// - The library code is copied into the script code
/// - Best for most user-written libraries and dependencies
/// - Results in larger script size but ensures the code is always available
///
/// **Dynamic Linking** (`link_dynamic_library()` / `with_dynamically_linked_library()`):
/// - Use when making Foreign Procedure Invocation (FPI) calls
/// - The library code is available on-chain and referenced, not copied
/// - Results in smaller script size but requires the code to be available on-chain
///
/// ## Typical Workflow
///
/// 1. Create a new CodeBuilder with debug mode preference
/// 2. Add any required modules using `link_module()` or `with_linked_module()`
/// 3. Add libraries using `link_static_library()` / `link_dynamic_library()` as appropriate
/// 4. Compile your script with `compile_note_script()` or `compile_tx_script()`
///
/// Note that the compiling methods consume the CodeBuilder, so if you need to compile
/// multiple scripts with the same configuration, you should clone the builder first.
///
/// ## Builder Pattern Example
///
/// ```no_run
/// # use anyhow::Context;
/// # use miden_standards::code_builder::CodeBuilder;
/// # use miden_protocol::assembly::Library;
/// # use miden_protocol::CoreLibrary;
/// # fn example() -> anyhow::Result<()> {
/// # let module_code = "pub proc test push.1 add end";
/// # let script_code = "begin nop end";
/// # // Create sample libraries for the example
/// # let my_lib: Library = CoreLibrary::default().into(); // Convert CoreLibrary to Library
/// # let fpi_lib: Library = CoreLibrary::default().into();
/// let script = CodeBuilder::default()
///     .with_linked_module("my::module", module_code).context("failed to link module")?
///     .with_statically_linked_library(&my_lib).context("failed to link static library")?
///     .with_dynamically_linked_library(&fpi_lib).context("failed to link dynamic library")?  // For FPI calls
///     .compile_tx_script(script_code).context("failed to parse tx script")?;
/// # Ok(())
/// # }
/// ```
///
/// # Note
/// The CodeBuilder automatically includes the `miden` and `std` libraries, which
/// provide access to transaction kernel procedures. Due to being available on-chain
/// these libraries are linked dynamically and do not add to the size of built script.
