fish shell features and specs

  • User-Friendly Syntax
    Fish shell features a more readable and user-friendly syntax compared to traditional shells like Bash or Zsh, making it easier for new users to learn and use.
  • Modern Features
    Fish shell includes out-of-the-box support for modern shell features such as syntax highlighting, autosuggestions, and smart command-line completions, greatly enhancing the user experience.
  • Web-Based Configuration
    Users can configure Fish shell through a web interface, making it more accessible and easier to customize compared to other shells that require manual configuration file edits.
  • Consistent Scripting
    Fish shell uses a consistent scripting language, which reduces the quirks and peculiarities often found in other shell scripting languages.

Possible disadvantages of fish shell

  • Compatibility Issues
    Fish shell is not POSIX compliant, which means scripts written in Fish will not be compatible with other POSIX-compliant shells like Bash or Zsh, potentially causing issues in environments that rely on such standards.
  • Smaller Ecosystem
    Compared to shells like Bash and Zsh, Fish has a smaller ecosystem of plugins, themes, and community support, which could limit available resources and tools.
  • Learning Curve for Experienced Users
    Experienced users of traditional shells like Bash or Zsh might find Fish's different syntax and features take some time to adapt to, potentially reducing initial productivity.
  • Limited Script Portability
    Scripts written in Fish shell are often not portable to other shell environments without significant modification, reducing their usability in multi-shell setups.

LLVM features and specs

  • Modularity
    LLVM is designed to be modular and flexible, allowing developers to utilize only the components they need for their specific tasks. This makes it versatile for a wide range of use cases.
  • Optimization
    LLVM provides advanced optimization techniques that allow for efficient code execution across various platforms. It utilizes a variety of standard and state-of-the-art optimization passes to improve performance.
  • Cross-Platform Support
    LLVM supports a wide range of architectures and platforms, enabling developers to build and deploy applications across multiple target environments without needing to make significant code changes.
  • Rich Ecosystem
    The LLVM project includes a wide array of tools and libraries, such as Clang and LLDB, that enhance development capabilities and provide comprehensive support for different programming languages.
  • Community and Industry Adoption
    LLVM has a robust and active community, along with backing from major technology companies. This means consistent updates, improvements, and a broad support network for troubleshooting and enhancements.

Possible disadvantages of LLVM

  • Complexity
    Due to its extensive feature set and flexibility, LLVM can be complex to understand and use, particularly for newcomers who may find its detailed API and documentation challenging.
  • Resource Intensive
    The advanced optimizations and capabilities provided by LLVM can require significant compute resources, which might not be suitable for all systems or use cases, particularly those with limited capabilities.
  • Steep Learning Curve
    LLVM's power and flexibility come with a steep learning curve, demanding a strong understanding of compiler design and architecture to fully leverage its potential.
  • Limited Legacy Support
    While LLVM supports many modern architectures, its focus on newer platforms means that it may offer limited functionality for legacy systems or older processor architectures.
  • Lack of High-Level Language Features
    LLVM is primarily focused on compiler and intermediate representation infrastructure, which means that it does not provide some high-level language features or abstractions unless provided by front-end tools.

  • A short tutorial on using fish shell.
    Follow this to install. Note that this tutorial assume that you are on Linux. - Source: dev.to / 10 days ago
  • Tools for 2025
    I've probably been using fish shell [0] for close to 10 years now. When I need POSIX compliance or if I need to run a one-off bash command, I just call bash. It's exceedingly rare. Browsing through the documentation for Oils, it seems to be organized in a way that's very confusing. When you open the fish shell website it was two clear buttons for Tutorial and Documentation.

  • TIL: Ghostty — a new and quite promising terminal emulator
    I remember that Julia Evans, whose blog I follow, mentioned a few time that she uses Fish. Also, some days ago I came across this post about Fish rewrite to Rust from C++, which sounds like a cool thing to do. However, I tried it some time ago, and while pretty neat, I wasn't convinced to switch to it completely. - Source: dev.to / 4 months ago
  • Easy development environments with Nix and Nix flakes!
    The default shell in the above flake adds Valkey, NodeJS 22, the PNPM package manager, and the fish shell to the environment. It also starts Valkey in the background through a shell hook, passing it a custom config (declared via Nix!) and runs fish so we're dropped in the fish shell instead of our login shell. - Source: dev.to / 4 months ago
  • A new shell for using modern Unix commands
    I’m testing a new shell called fish, and I’m enjoying some features that truly make it a friendly interactive shell. - Source: dev.to / 4 months ago

  • Why you should keep an eye on Apache DataFusion and its community.
    Similarly, LLVM revolutionized the world of programming languages and compilers. Since its creation, we've seen many new languages being created of increased complexity. - Source: dev.to / 10 months ago
  • Yes, Ruby is fast, but…
    In conclusion, none of the proposed changes to the Ruby version of the code makes a dent in the Crystal version. This is not entirely Crystal's doing: it uses the LLVM backend, which generates very optimized binaries. - Source: dev.to / about 1 year ago
