Possible disadvantages of PyCharm

  • Resource Intensive
    PyCharm can be quite heavy on system resources, consuming significant memory and CPU, which can slow down the system, especially on machines with lower specifications.
  • High Cost
    PyCharm's Professional Edition is a paid product, which might not be feasible for individual developers or small teams with limited budgets, although a free Community Edition is available.
  • Steep Learning Curve
    Due to its extensive feature set, PyCharm can be overwhelming for beginners, and it may take some time for new users to become proficient with all its functionalities.
  • Occasional Performance Issues
    Some users report occasional performance lags and stability issues, especially when working on large projects or while using certain plugins.
  • Frequent Updates
    While updates are generally a positive feature, PyCharm's frequent updates can sometimes disrupt workflow and necessitate reconfiguring settings or updates to plugins.

  • Steep Learning Curve
    The editor may have a steep learning curve for users unfamiliar with Common Lisp or those new to more complex and highly customizable text editors.
  • Limited Community Support
    Lem has a smaller user base compared to more established editors, which might result in less community support, fewer plugins, and less frequent updates.
  • Dependency on Lisp Environment
    Lem's reliance on a Common Lisp environment could be cumbersome for users not already utilizing Lisp or who require additional setup time to configure their environment.

The Rise of Microsoft Visual Studio Code
The percentages on this graph are per editor. So we can see, for example, that 97% of engineers using PyCharm program in Python (which makes sense — it's in the name). Eclipse is dominated by Java (94%) and Visual Studio is mostly C# and C++ (88%).

  • Emacs Is a Lispboard
    Something like Lem[1][2] could go even further because of the richer CommonLisp ecosystem compared to Elisp one. [1] https://lem-project.github.io/ [2] https://github.com/lem-project/lem. - Source: Hacker News / about 1 month ago
  • My I3-Emacs Integration
    Sounds like you want Lem. Though it's common lisp instead of guile. https://github.com/lem-project/lem. - Source: Hacker News / 3 months ago
  • Editing Code in Emacs
    Thanks for sharing. I've been off editor hopping for quite some time, nowadays I just use some pre-defined configuration like Doom Emacs, occasionally I try to build some environment, with AI help, from "scratch" for fun and curiosity. I really like Emacs' flexibility + evil-mode and reactivity, recently I searched for something similar and found Lem: https://github.com/lem-project/lem, looks promising, I'll try... - Source: Hacker News / 9 months ago
  • IDEmacs: A Visual Studio Code clone for Emacs
    I don't agree with everything in their approach, but Lem (https://github.com/lem-project/lem) is a modern editor that has the Emacs Nature. - Source: Hacker News / 10 months ago
  • IDEmacs: A Visual Studio Code clone for Emacs
    It's not exactly what you're looking for but you might be interested in Lem[0]. It's an emacs-style editor but written completely in Common Lisp on top of curses/SDL2. I haven't used it that much (same for Emacs itself, really), but it looks like a very solid foundation [0]: https://github.com/lem-project/lem. - Source: Hacker News / 10 months ago
