  • Cross-platform Support
    CCL runs on multiple platforms including macOS, Linux, and Windows, facilitating development across different operating systems.
  • Dynamic Typing and Flexibility
    CCL, like other Lisp dialects, offers dynamic typing and flexibility which allows developers to write code that can be easily modified and extended.
  • Interactivity
    CCL provides a powerful interactive development environment with a Read-Eval-Print Loop (REPL), allowing developers to test and debug code on the fly.
  • Compatibility with Common Lisp
    Being a comprehensive implementation of Common Lisp, CCL supports a wide range of Lisp features, making it compatible with existing Common Lisp codebases.
  • Active Community
    CCL has an active community that contributes to its development and support, resulting in a wealth of libraries and resources.

Possible disadvantages of Clozure Common Lisp

  • Limited GUI Libraries
    Clozure Common Lisp's support for graphical user interfaces is limited compared to other platforms, which may require additional effort for developing desktop applications.
  • Smaller User Base
    Compared to more mainstream languages like Python or Java, CCL has a smaller user base, which may result in less community support and fewer third-party libraries.
  • Steep Learning Curve
    As with many Lisp dialects, CCL can have a steep learning curve for developers unfamiliar with Lisp syntax and concepts.
  • Less Documentation
    Although there is documentation available, it may not be as extensive or detailed as that for more widely-used languages, potentially hindering new users.
  • Interoperability Challenges
    While CCL can interoperate with C and other languages, setting this up can be complex and may pose challenges for developers needing seamless integration.

Expresso features and specs

  • User-Friendly Interface
    Expresso has an intuitive and user-friendly interface that makes it easy for both novice and experienced users to create and test regular expressions.
  • Comprehensive Test Environment
    It includes a detailed test environment where users can test their regular expressions against sample text to ensure accuracy and efficiency.
  • Integrated Syntax Highlighting
    The tool provides syntax highlighting to help users identify different parts of their expressions easily, which can reduce errors and improve readability.
  • Extensive Library of Expressions
    Expresso features a library of pre-built regular expressions that users can use as a reference or starting point for their own expressions, saving time and effort.
  • Educational Resources
    It offers numerous tutorials and guides that can help users understand regular expressions better and improve their skills progressively.

Possible disadvantages of Expresso

  • Limited to Windows
    Expresso is only available for Windows operating systems, which limits its accessibility to users on other platforms like macOS or Linux.
  • Outdated User Interface
    Some users might find the user interface to be somewhat outdated compared to more modern applications, which could impact the user experience.
  • Lack of Advanced Features
    While useful for basic and intermediate tasks, Expresso might lack some advanced features and customization options found in more comprehensive regex tools.
  • No Collaboration Features
    The application does not offer any features for collaboration, which might be a drawback for teams working together on complex projects.
  • No Cloud Integration
    Expresso does not offer cloud integration, meaning users cannot easily sync their work across multiple devices or share it through cloud services.

  • Graphics Livecoding in Common Lisp
    Unfortunately CCL is Intel only on macOS. (macOS is not on the the main page https://ccl.clozure.com) Otherwise this is the one I would use as it has good Cocoa interoperability. - Source: Hacker News / about 1 month ago
  • The IDEs we had 30 years ago and we lost
    The descendant of CCL runs on modern Intel Macs. (It also runs on Linux and Windows but without the IDE.) The modern IDE is quite a bit different from the original. In particular, it no longer has the interface builder. But it's still pretty good. It is now called Clozure Common Lisp (so the acronym is still CCL) and you can find it here: https://ccl.clozure.com/ If you want to run the original that is a bit... - Source: Hacker News / over 1 year ago
  • The Saga of the Closure Compiler, and Why TypeScript Won
    Just for fun there is also Clozure Common Lisp. https://ccl.clozure.com/. - Source: Hacker News / over 1 year ago
  • Consuming HTTP endpoint using Common Lisp
    I have decided it is time to have some fun and use Common Lisp to create algorithm representation that deals with parallel execution. For this I decided to use Clozure common lisp, put basic Qucklisp there and load some libraries to do this. - Source: dev.to / over 2 years ago
