lib/charms/intrinsic.ex (3)
1-4: Consider expanding the module documentation.The current documentation is concise, but it could be more informative. Consider adding more details about the purpose of intrinsic functions in the context of your project, and perhaps include an example of how this behavior is intended to be used.
Here's a suggestion for an expanded documentation:
@moduledoc """ Behaviour to define intrinsic functions. Intrinsic functions are special operations that are directly handled by the compiler or runtime system, often for performance reasons. This module provides a standardized way to define and handle such functions in the context of the Charms library. Example usage: defmodule MyIntrinsics do use Charms.Intrinsic def handle_intrinsic(:my_special_op, args, opts) do # Implementation end end """
6-7: Consider improving type names and adding type documentation.The type definitions are correct, but their names and lack of documentation may make their purpose unclear. Consider the following improvements:
- Rename
opttointrinsic_optionandoptstointrinsic_optionsfor clarity.- Add
@typedoccomments to explain the purpose of each type.Here's a suggested improvement:
@typedoc """ Represents a single option for an intrinsic function, which can be either a context or a block. """ @type intrinsic_option :: {:ctx, MLIR.Context.t()} | {:block, MLIR.Block.t()} @typedoc """ Represents a list of options for an intrinsic function, which can include intrinsic_option or other key-value pairs. """ @type intrinsic_options :: [intrinsic_option | {atom(), term()}]
8-8: Add documentation for the handle_intrinsic callback.The
handle_intrinsic/3callback is defined, but its purpose and usage are not immediately clear. Consider adding a@doccomment to explain:
- The purpose of the callback
- What the atom argument represents
- What the list of terms typically contains
- How the options are used
- What kind of term is expected to be returned
Here's a suggested improvement:
@doc """ Handles the execution of an intrinsic function. ## Parameters * `intrinsic_name` - An atom representing the name of the intrinsic function. * `args` - A list of terms representing the arguments passed to the intrinsic function. * `opts` - A list of options (of type `t:intrinsic_options/0`) for the intrinsic function execution. ## Returns Returns the result of the intrinsic function execution, which can be any term. ## Examples def handle_intrinsic(:my_intrinsic, [arg1, arg2], opts) do # Implementation end """ @callback handle_intrinsic(intrinsic_name :: atom(), args :: [term()], opts :: intrinsic_options()) :: term()bench/vec_add_int_list.ex (4)
1-4: Consider adding module documentation.While
@moduledoc falseis set, which is often used for internal modules, it's generally a good practice to provide documentation for all modules. This helps other developers understand the purpose and usage of the module, especially in a benchmarking context.Consider adding a brief module description, for example:
@moduledoc """ Benchmark module for vector addition operations using SIMD instructions. This module demonstrates the performance of vector operations compared to standard list operations. """

6-20: Address TODO and consider minor optimization.The
load_list/2function looks well-implemented, but there are a couple of points to consider:
There's a TODO comment about removing the const when pointer type can be inferred. It would be good to create a tracking issue for this improvement.
A minor optimization could be made by pre-allocating the
v_ptroutside theEnum.reduceloop, as its allocation doesn't depend on the loop's state.Consider refactoring the function as follows:
defm load_list(env, l :: Term.t()) :: SIMD.t(i32(), 8) do i_ptr = Pointer.allocate(i32()) v_ptr = Pointer.allocate(i32()) # TODO: remove the const here, when pointer's type can be inferred Pointer.store(const(0 :: i32()), i_ptr) init = SIMD.new(i32(), 8).(0, 0, 0, 0, 0, 0, 0, 0) Enum.reduce(l, init, fn x, acc -> enif_get_int(env, x, v_ptr) i = Pointer.load(i32(), i_ptr) Pointer.store(i + 1, i_ptr) Pointer.load(i32(), v_ptr) |> vector.insertelement(acc, i) end) |> func.return() endWould you like me to create a GitHub issue to track the TODO for removing the const when pointer type inference is improved?

47-51: Add documentation and address unused variables.The
dummy_load_no_make/4function appears to be for benchmarking purposes, but its intention is not immediately clear. Consider the following suggestions:
- Add a function comment explaining its purpose in the benchmarking process.
- Address the unused variables
v1andv2to avoid potential compiler warnings.Here's a suggested refactoring:
@doc """ Benchmark function to measure the overhead of `load_list/2` without addition and list construction. """ defm dummy_load_no_make(env, a, b, error) :: Term.t() do _v1 = call load_list(env, a) :: SIMD.t(i32(), 8) _v2 = call load_list(env, b) :: SIMD.t(i32(), 8) func.return(a) endThis change adds documentation and uses underscores to indicate that
v1andv2are intentionally unused, which should prevent compiler warnings.
Line range hint
53-55: Add documentation and address unused parameters.The
dummy_return/4function appears to be for benchmarking purposes, specifically to measure the baseline overhead of function calls. Consider the following suggestions:
- Add a function comment explaining its purpose in the benchmarking process.
- Address the unused parameters
banderrorto avoid potential compiler warnings.Here's a suggested refactoring:
@doc """ Benchmark function to measure the baseline overhead of function calls. """ defm dummy_return(env, a, _b, _error) :: Term.t() do func.return(a) endThis change adds documentation and uses underscores to indicate that
banderrorare intentionally unused, which should prevent compiler warnings.lib/charms.ex (5)
4-23: Enhance documentation structure for clarityThe documentation between lines 4-23 can be improved for better readability and understanding. Consider organizing the content using more structured headings and consistent formatting.
Consider applying the following changes:
-## `defm` and intrinsic -There are two ways to define a function with `defm/2` or implement callbacks of `Charms.Intrinsic` behavior. The `defm/2` is a macro that generates a function definition in Charm. The intrinsic is a behavior that generates a function definition in MLIR. - -The intrinsic is more flexible than `defm` because: -- Intrinsic can be variadic and its argument can be anything -- Intrinsic is suitable for the cases where directly writing or generating MLIR is more ideal -- An intrinsic should be responsible for its type check while the Charm’s type system is responsible for function call’s type check - -The `defm` is more suitable for simple functions because it is designed to be as close to vanilla Elixir as possible. As a rule of thumb, use `defm` for simple functions and intrinsic for complex functions or higher-order(generic) function with type as argument. - -## `defm`'s differences from `Beaver.>>>/2` op expressions -- In `Beaver.>>>/2`, MLIR code are expected to mixed with regular Elixir code. While in `defm/2`, there is only Elixir code (a subset of Elixir, to be more precise). -- In `defm/2`, the extension of the compiler happens at the function level (define your intrinsics or `defm/2`s), while in `Beaver.>>>/2`, the extension happens at the op level (define your op expression). -- In `Beaver.>>>/2` the management of MLIR context and other resources are done by the user, while in `defm/2`, the management of resources are done by the `Charms` compiler. -- In `defm/2`, there is expected to be extra verifications built-in to the `Charms` compiler (both syntax and types), while in `Beaver.>>>/2`, there is none. - -## Caveats and limitations - -We need a explicit `call` in function call because the `::` special form has a parser priority that is too low so a `call` macro is introduced to ensure proper scope. +### `defm` and Intrinsics +There are two ways to define a function: + +1.

28-28: Redundant import ofCharmsAt line 28, importing
Charmswithin theCharmsmodule is unnecessary since the module has access to its own functions.Consider removing the redundant import:
- import Charms
62-64: Expand documentation fordefm/2macroThe documentation for
defm/2is brief. Providing detailed descriptions and examples will help users understand its purpose and usage.Consider enhancing the documentation:
@doc """ -define a function that can be JIT compiled +Defines a function that can be Just-In-Time (JIT) compiled. + +`defm/2` is a macro that allows you to define functions in a way that integrates with the Charms JIT compilation framework. + +## Examples + + defmodule MyModule do + use Charms + + defm my_function(arg1 :: type1, arg2 :: type2) :: return_type do + # function body + end + end + +This macro simplifies the process of defining functions that can be compiled and optimized at runtime.

_enif_envis not needed, you can omit it for clarity:-[_enif_env | invoke_args] = args +invoke_args = argsIf it is reserved for future use or required for interface compliance, consider adding a comment explaining its purpose.
76-80: Improve clarity ininvoke_argstransformationThe loop transforming

- Add a comment explaining why
Beaveris included and what functionality it provides.- Add
@docdocumentation for the__using__macro to explain how it should be used.Here's a suggested improvement:
@doc """ When used, defines the module as implementing the `Charms.Intrinsic` behavior. This macro does the following: 1. Sets up the module to implement the `Charms.Intrinsic` behavior. 2.

1-55: Overall, well-implemented module with room for minor improvements.The
AddTwoIntVecmodule effectively implements vector addition using SIMD instructions and provides benchmark functions to measure different aspects of the implementation. The code is well-structured and makes good use of theCharmslibrary for low-level operations.Some final suggestions for improvement:
- Consider adding more comprehensive error handling, especially in the
add/4function.- Explore opportunities for further optimization, particularly in the list construction part of
add/4.- Ensure consistent use of vector size across the module, possibly by introducing a module attribute.
- Add more detailed documentation for each function, explaining their role in the benchmarking process.
To further improve the module's architecture and maintainability:
- Consider extracting the SIMD vector size into a module attribute for easy adjustment:
@vector_size 8- If this module is part of a larger benchmarking suite, consider creating a behaviour or protocol that defines a common interface for different benchmark implementations. This would make it easier to compare different approaches consistently.
To ensure the consistency of the implementation, we can run the following checks:
#!/bin/bash # Check for consistent use of vector size rg --type elixir "SIMD\.t\(i32\(\), \d+\)" bench/vec_add_int_list.ex # Check for potential unused variables or parameters rg --type elixir "\w+(?=\s*[,)])" bench/vec_add_int_list.exThese checks will help identify any inconsistencies in vector size usage and potential unused variables or parameters across the module.

22-45: Consider error handling and potential optimization.The
add/4function effectively implements vector addition using SIMD instructions. However, there are a few points to consider:
Error Handling: The
errorparameter is not used. Consider implementing error handling, especially for cases where the input lists might have different lengths or be empty.Optimization: The extraction and list construction could potentially be optimized by using a loop or a more efficient NIF function if available.
Magic Number: The function assumes a vector size of 8. Consider making this a module attribute for better maintainability.
Here's a suggested refactoring:
@vector_size 8 defm add(env, a, b, error) :: Term.t() do try do v1 = call load_list(env, a) :: SIMD.t(i32(), @vector_size) v2 = call load_list(env, b) :: SIMD.t(i32(), @vector_size) v = arith.addi(v1, v2) result = for i <- 0..(@vector_size - 1) do enif_make_int(env, vector.extractelement(v, const(i :: i32()))) end list = :erlang.list_to_tuple(result) ret = :erlang.apply(&enif_make_list/2, [env | :erlang.tuple_to_list(list)]) func.return(ret) catch _ -> enif_make_badarg(env) end endThis refactoring introduces error handling, uses a module attribute for the vector size, and potentially optimizes the list construction. Note that the exact syntax for the optimized list construction might need adjustment based on the specific capabilities of your NIF environment.
To ensure the correctness of the vector size assumption, we can check if it's used consistently across the module:
lib/charms.ex (1)
81-97: 🛠️ Refactor suggestionRefactor nested conditionals for better readability
Lines 81-97 contain nested
ifstatements that can be refactored to improve readability and reduce complexity.Consider simplifying the function:
def unquote(name)(unquote_splicing(invoke_args)) do if @init_at_fun_call do {_, %Charms.JIT{}} = Charms.JIT.init(__MODULE__) end f = &Charms.JIT.invoke(&1, {unquote(env.module), unquote(name), unquote(invoke_args)}) - if engine = Charms.JIT.engine(__MODULE__) do - f.(engine) - else - f - end + engine = Charms.JIT.engine(__MODULE__) + f.(engine) endThis assumes that
Charms.JIT.engine(__MODULE__)returns a valid engine, or you may need to handle the case when it returnsnil.Ensure that
Charms.JIT.engine/1always returns a valid engine or handle thenilcase appropriately.lib/charms/defm.ex (1)
63-63: Assess the necessity of changingnormalize_call/1to publicThe function
normalize_call/1has been changed from private (defp) to public (def). If it's intended for external use, making it public is appropriate. However, if it's only used internally withinCharms.Defm, consider keeping it private to encapsulate implementation details.To verify whether
normalize_call/1is used outsideCharms.Defm, you can run the following script:✅ Verification successful

1-9: Summary of changes and potential impact.The changes in this file appear to be part of a larger refactoring effort, transitioning from
BeavertoCharms.Intrinsic. While the modifications are straightforward, they may have broader implications on the project structure and dependencies. Key points to consider:
- Ensure that
Charms.Intrinsicprovides all necessary functionality previously offered byBeaver.- Verify that the continued use of
Beaver.ENIF.Type.term/1is intentional and doesn't introduce inconsistencies.- Check if similar changes are required in other modules that may have been using
Beaver.- Update any documentation or tests that may be affected by this change.
Consider creating a migration guide or updating the project documentation to reflect these architectural changes, especially if
Charms.Intrinsicis intended to replaceBeaveracross the project..github/workflows/elixir.yml (2)
51-53: Good addition of packaging step, but consider enhancing its utility.The inclusion of the "Package" step using
mix archive.buildis a positive addition to the CI workflow. It ensures that the project can be successfully packaged, which can help catch packaging-related issues early in the development process.However, to maximize the value of this step, consider the following suggestions:
- Store the generated archive as an artifact of the workflow. This can be done using the
actions/upload-artifactaction.- Add a step to verify the contents of the generated archive.
- If applicable, consider using this archive for deployment or distribution purposes.
Here's an example of how you might enhance this step:
- name: Package run: mix archive.build - name: Upload package uses: actions/upload-artifact@v2 with: name: package path: *.ez
48-53: Great enhancements to the CI workflow, with room for future improvements.The addition of the "Document" and "Package" steps significantly improves the CI workflow by incorporating important aspects of the software development lifecycle. These changes ensure that documentation is kept up-to-date and that the project can be successfully packaged with each build.
To further enhance the workflow in the future, consider:
- Publishing the generated documentation to a hosting service (e.g., GitHub Pages) for easy access.
- Utilizing the generated package for deployment or distribution purposes.
- Adding a step to run a documentation linter to ensure consistency and quality.
- Implementing version bumping and changelog generation as part of the CI process.
These additions have laid a strong foundation for a more comprehensive CI/CD pipeline. Great work!

5-7: Consider expanding intrinsic type handling and verify Beaver dependency.The new
handle_intrinsic/3function looks good for handling the:ttype. However, consider the following points:
- Are there other intrinsic types that need handling? If so, consider adding them or using a more flexible pattern matching approach.
- The function is still using
Beaver.ENIF.Type.env(opts). Verify if this is intentional or if it should be replaced with aCharms-specific function.To verify the usage of intrinsic types and Beaver dependency, please run the following script:

12-12: Good addition of defintrinsic directiveThe
defintrinsic [:t]directive correctly declares:tas an intrinsic type for this module, which is consistent with thehandle_intrinsic/3function implementation.Consider adding a brief comment explaining the purpose of this directive for improved code clarity. For example:
# Declare :t as an intrinsic type handled by this module defintrinsic [:t]lib/charms/simd.ex (1)

10-28: Improved handle_intrinsic implementation with suggestionThe updates to the
handle_intrinsicfunction are well-structured and include good error handling. The nested function for processingliteral_valuesimproves code organization.However, there's a minor optimization opportunity:
Consider combining the
Enum.mapandEnum.countoperations to avoid iterating over the list twice:{values, count} = Enum.map_reduce(literal_values, 0, fn val, acc -> {Attribute.integer(type, val), acc + 1} end) if count != width do raise ArgumentError, "expected #{width} values, got #{count}" endThis change would slightly improve performance, especially for larger lists.

1-5: Enhance module documentation and clarifyBeaveralias.The module documentation provides a brief description of its purpose. Consider expanding it to include:
- More details on what intrinsic functions are in this context.
- How to use this module.
- Any important considerations for implementers.
Also, the purpose of the
Beaveralias is not immediately clear. Consider adding a comment explaining its role in this module.
6-8: Add documentation for types and callback.Consider adding
@typedocfor bothoptandoptstypes to explain their purpose and usage. Also, add@docfor thehandle_intrinsic/3callback to describe its expected behavior, parameters, and return value.Example:
@typedoc """ Represents either a context or a block from the MLIR library. """ @type opt :: {:ctx, MLIR.Context.t()} | {:block, MLIR.Block.t()} @doc """ Handles the intrinsic function call. ## Parameters - atom: The name of the intrinsic function. - [term()]: List of arguments passed to the intrinsic function. - opts(): Options for the intrinsic function. ## Returns The result of the intrinsic function call. """ @callback handle_intrinsic(atom(), [term()], opts()) :: term()
9-18: Improvecollect_intrinsicsfunction with a guard clause.The
collect_intrinsicsfunctions look good overall. For the second function, consider using a guard clause for better clarity:def collect_intrinsics(attr_list) when is_list(attr_list) and length(attr_list) > 0 do attr_list |> Enum.reverse() |> List.flatten() |> Enum.uniq() endThis change makes the function's expectations more explicit and can help catch potential errors earlier.
29-42: Add documentation fordefintrinsicand__before_compile__macros.Consider adding
@docstrings for both macros to improve usability:@doc """ Registers intrinsic functions for the module. ## Example defintrinsic [:my_intrinsic1, :my_intrinsic2] """ defmacro defintrinsic(intrinsic_list) do # ... existing implementation ... end @doc false defmacro __before_compile__(_env) do # ... existing implementation ... endNote that
__before_compile__typically doesn't need public documentation as it's used internally by the module system.lib/charms/pointer.ex (1)
5-5: LGTM: Use of Charms.Intrinsic and @impl true added.The change from
BeavertoCharms.Intrinsicaligns with the PR objectives. The@impl trueattribute is correctly placed before the first callback implementation.Consider adding
@impl truebefore eachhandle_intrinsicfunction to improve code clarity, as suggested in a previous review comment.Also applies to: 9-9

lib/charms/env.ex (2)
2-4: Great addition of module documentation!The added module documentation clearly describes the purpose of the
Charms.Envmodule. This improves code readability and helps other developers understand the module's role in the project.
7-10: Implementation looks good, but verify behavior declarationThe
handle_intrinsic/3function is correctly implemented for the:ttype. However, there's a potential issue with the@impl trueattribute.Please ensure that:
- The
Charms.Intrinsicmodule (or a module in its hierarchy) declares a behavior that includes thehandle_intrinsic/3callback.- If no such behavior exists, consider removing the
@impl trueattribute to avoid potential inconsistencies.To verify the behavior declaration, run the following script:
#!/bin/bash # Description: Check for behavior declaration in Charms.Intrinsic or its parent modules # Search for behavior declaration echo "Searching for behavior declaration:" rg --type elixir '(defprotocol|@callback)\s+handle_intrinsic' lib/charms/lib/charms/simd.ex (2)
9-9: Good use of @impl true annotationThe addition of
@impl trueis a good practice. It clearly indicates that the following function is implementing a behavior, which helps with code readability and can catch errors if the implemented function doesn't match the behavior specification.
30-30: Clarify the purpose and implementation of defintrinsicThe addition of
defintrinsic [:new, :t]appears to be declaring intrinsic functions for the module. However, without more context about thedefintrinsicmacro, it's challenging to determine if this is correctly implemented or if it might have any side effects.Could you provide more information about the
defintrinsicmacro? Specifically:
- What does it do?
- Are there any side effects we should be aware of?
- Is this the correct way to use it for this module?

This will help us understand how
defintrinsicis used in other parts of the codebase and ensure consistency.✅ Verification successful
Verified the implementation of
defintrinsicAfter reviewing the implementation and usage of the
defintrinsicmacro across the codebase, the addition ofdefintrinsic [:new, :t]inlib/charms/simd.exaligns with the established pattern. The macro is consistently used to declare intrinsic functions, and its definition inlib/charms/intrinsic.exsupports this usage without any apparent issues.🏁 Scripts executed

20-27: LGTM: Well-structured__using__macro.The
__using__macro is well-structured and follows good practices:
- It sets up the behavior correctly.
- Uses
@before_compilefor finalizing module setup.- Selectively imports macros to avoid namespace pollution.
This provides a clean interface for modules adopting this behavior.
1-43: Overall assessment: Well-structured module with minor improvement opportunities.The
Charms.Intrinsicmodule provides a solid foundation for defining and managing intrinsic functions. It effectively uses Elixir's metaprogramming capabilities to create a clean interface for other modules to adopt this behavior.Key strengths:
- Clear separation of concerns with well-defined types and callbacks.
- Effective use of Elixir's module attributes and macros.
- Good error handling in the
collect_intrinsicsfunction.Suggested improvements mainly focus on enhancing documentation and minor optimizations, which will further improve the module's usability and maintainability.
Great job on implementing this intrinsic function handling system!
lib/charms/pointer.ex (2)
2-4: LGTM: Module documentation added.The added module documentation clearly describes the purpose of the
Charms.Pointermodule. This improves code readability and maintainability.
59-59: LGTM: Intrinsic functions declared.The
defintrinsicdeclaration formalizes the intrinsic operations supported by the module. This improves code clarity and aligns with the existinghandle_intrinsicfunctions.lib/charms/prelude.ex (3)
2-5: LGTM: Module documentation and use statement.The added module documentation and the change to
use Charms.Intrinsiclook good and align with the PR objectives.Consider updating remaining
Beaverreferences.There are still references to
Beaverin the aliases and function calls. Consider updating these to maintain consistency with the change toCharms.Intrinsic.
114-114: LGTM: Consolidated intrinsic definitions.The addition of the
defintrinsicfunction call consolidates the intrinsic definitions into a single declaration. This improves code maintainability and readability.
113-113:⚠️ Potential issuePotential issue with unused parameter in handle_intrinsic/3.
The new implementation of
handle_intrinsicfor:result_atdoesn't use theiparameter. This might be unintended if the goal is to retrieve a specific result based on the indexi.Consider modifying the function to utilize the index
ito access the desired result fromv. Ifiis not needed, it might be better to remove it from the parameters to avoid confusion.lib/charms/defm/expander.ex (1)
480-483: Improved intrinsic function handling inexpand_remote/5The updated logic correctly checks whether the
moduleexports__intrinsics__/0and whetherfunis included in the list returned bymodule.__intrinsics__/0. This change enhances the detection and handling of intrinsic functions during remote calls, improving the robustness and maintainability of the code.

1-5: Consider expanding the module documentation.The current documentation provides a concise description of the module's purpose. However, it could be beneficial to expand it with more context about intrinsic functions and their role in the Charms library. This would help users better understand the module's functionality and its place in the larger system.
6-9: Add inline documentation for type definitions.The type definitions are clear, but adding inline documentation for each type would improve code readability and maintainability. Consider adding
@typedoccomments to explain the purpose and usage of each type.Example:
@typedoc "Represents either a context or a block from the MLIR library." @type opt :: {:ctx, MLIR.Context.t()} | {:block, MLIR.Block.t()}
21-30: Consider adding a guard clause for an empty list incollect_intrinsics/1.The
collect_intrinsics/1function handles thenilcase and the case when the list has at least one element. However, it doesn't explicitly handle an empty list. Consider adding a guard clause for an empty list to make the function more robust.Suggested improvement:
def collect_intrinsics([]), do: raise ArgumentError, "no intrinsic functions defined" def collect_intrinsics(attr_list) when is_list(attr_list) and length(attr_list) > 0 do attr_list |> Enum.reverse() |> List.flatten() |> Enum.uniq() end
32-54: Well-implemented macros with a suggestion for clarity.The macros for
__using__/1,defintrinsic/1, and__before_compile__/1are well-implemented and provide the necessary functionality for using theCharms.Intrinsicbehavior.For improved clarity, consider adding a brief comment above each macro explaining its purpose. This would make the code more self-documenting and easier to understand for other developers.
Example:
# Sets up the Charms.Intrinsic behavior and imports necessary macros defmacro __using__(_) do # ... existing code ... end # Defines intrinsic functions defmacro defintrinsic(intrinsic_list) do # ... existing code ... end # Finalizes the intrinsic list before compilation defmacro __before_compile__(_env) do # ... existing code ... end

4-24: Excellent documentation improvements!The added documentation provides valuable context and explanations for
defm/2and intrinsics. It clearly outlines their differences, use cases, and limitations, which will greatly assist developers in using the library effectively.Consider adding a brief example of using
defm/2and an intrinsic to further illustrate their usage and differences.
60-95: Well-implementeddefm/2macro with room for improvementThe implementation of the
defm/2macro looks good overall. It handles the complexities of preparing functions for JIT compilation effectively.To improve maintainability, consider breaking down the macro into smaller, more focused helper functions. This could make the code easier to understand and modify in the future. For example:
- Extract the argument normalization logic into a separate function.
- Create a helper function for generating the function body.
- Separate the JIT initialization logic into its own function.
This refactoring would make the main macro body more concise and easier to follow.

1-228: Summary of changes and their potential impactThe changes in this file represent a significant refactoring of the
Charms.Defmmodule:
- The removal of the
defmmacro is the most impactful change, potentially affecting dependent code throughout the project.- The
normalize_callfunction is now public, which may indicate new external usage.- The
decompose_call_with_return_typefunction replacesdecompose_call_and_returnswith a simpler implementation.These changes suggest a shift in the module's functionality and usage. To ensure a smooth transition:
- Update the module documentation to reflect its new purpose and functionality.
- Verify that all dependent code has been updated to account for the removal of the
defmmacro.- Review the need for
normalize_callto be public and add appropriate documentation if it's intended for external use.- Consider adding documentation to the new
decompose_call_with_return_typefunction.Given the significance of these changes, it would be beneficial to:
- Provide a migration guide for users of the
defmmacro, explaining how to update their code.- Update any related tests to ensure the new functionality is properly covered.
- Consider adding a deprecation notice in the previous version if this change breaks backward compatibility.
