API

Legacy Support

This can totally be described as a breaker. It includes radical changes in many places such as standard library, compiler and API. Therefore, updating the version may require additional effort, but it is definitely recommended.

Legacy Support

This version contains many bug fixes so updating is highly recommended. However, if you update it, your old codes may not compile and some performance problems may occur. For compilation issues, you need to update your code accordingly.

Here are some official tips for performance and interoperability issues:
First of all, there is not much change that could cause performance degradation. Therefore, there is only one specific point you need to look at: strings. Strings cause performance degradation mostly in concatenation operations. Since Jule used mutable strings in previous versions, it could handle this quite efficiently, but now immutable strings are used. Therefore, the cost of merging operations is significantly higher. For strings that you do a high amount of concatenation, use the StrBuilder structure provided by the std::strings package. This structure is designed to concatenate strings and treat them as a single string and should largely prevent performance loss.

Review where you rely on automatic conversion of strings for interoperability, otherwise some errors may occur in your program. This is because strings are now length-based rather than NULL terminated. This can lead to various errors due to the lack of NULL termination, especially when working with C-strings. For a safe conversion, the StrToBytes function is provided by the std::jule::integrated package. It is highly recommended to use this function for conversion.

If you are wondering why new strings are designed to be length-based rather than NULL termination, despite the risk of causing interoperability problems, it is recommended that you read this section in the manual: About Interoperability and Type Compatibility - Strings.

About Releases

Previous versions were marked as pre-release. It will no longer be marked. Since the bugs have been largely resolved and Jule is mature enough to be used for many tasks, it has been decided that beta versions will no longer be marked as pre-release. So this doesn't mean Jule is stable now. Compiler and standard library still may have some important bugs since Jule is still in beta.

Legacy Support

Jule code written for older versions is not guaranteed to compatible maintenance-free.

Legacy Support

Upgrading from previous versions may encounter compilation issues as important aspects such as the type system have been updated.

Experimental

The Windows AMD64 build is not compiled on a local machine, unlike previous versions. In order to reduce the release process to a single device as much as possible, it was compiled on a Windows ARM64 machine. Therefore, relevant build is experimental. Please let me know if there are any problems.

Beta 0.0.7

Language

• update rule: accept anonymous function fields as C++ functions of cpp-linked structures
• add: default expression support for structure fields
• add: the reserved to_str method for structures
• add: support for the <, >, <=, >= operators to the str type
• remove: built-in methods of the str type
• remove: the built-in Dispose trait and add the reserved dispose method instead

Compiler

• compiler: fix constant variable code generation
• compiler: add information message for blank execution
• compiler: improve c++14 compatibility
• compiler: improve runtime panics
• compiler: add the clang, gcc, cpp14, cpp17, and cpp20 variables to directive expressions
• compiler: add the -—disable-rc option to disable reference counting
• compiler: add the -—disable-safety option to disable safety measures
• compiler: add the —-opt-cond optimization flag
• compiler: fix code generation for testing
• lex: fix column data processing
• sema: add name selection support for impl types such as namespace selections
• sema: fix checking for the built-in clone function
• sema: fix constant bitwise eval

Release Period Update

Releases no more include build for the darwin-amd64 architecture.
Past builds has possible incompatibilities and etc. Sorry for that.
It can be still available via compile from source method, this is not darwin-amd64's end of life.
