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.

Mercurial SCM features and specs

  • Performance
    Mercurial is known for its speed and performance, especially with large repositories and complex histories. It is designed to be fast and efficient, which makes it suitable for large-scale projects.
  • Simplicity
    Mercurial has a simpler command set compared to other SCMs like Git. The straightforwardness of its commands can make it easier to learn and use, particularly for new users.
  • Cross-platform Support
    Mercurial is a cross-platform tool that works well on a variety of operating systems including Windows, macOS, and Linux. This makes it versatile for development teams using different environments.
  • Strong Documentation
    Mercurial offers comprehensive and well-structured documentation which can be very helpful for both beginners and advanced users. The documentation covers a wide range of topics from basics to more complex usage.
  • Branching Model
    Mercurial uses a simpler and more intuitive branching model compared to Git. This can make branch handling more straightforward, reducing the complexity for developers.

Possible disadvantages of Mercurial SCM

  • Smaller Community
    Mercurial has a smaller user base and community compared to Git. This might result in fewer third-party tools, plugins, and resources available for Mercurial.
  • Market Share
    Git has largely dominated the market share for SCM tools. This might make Mercurial less attractive for enterprises and developers who prefer widely-adopted tools with broad industry support.
  • Tool Integration
    Some software tools and services offer better integration with Git than with Mercurial. This can limit the choices for CI/CD pipelines or other development tools that are often built with Git compatibility first.
  • Complex History Management
    While Mercurial’s simpler commands are an advantage, it can make some complex history management tasks more challenging compared to Git, which has a more powerful set of tools for such purposes.
  • Feature Lag
    New features and updates in source control management tend to appear in Git before they make their way to Mercurial, if at all. This lag can be a disadvantage for teams looking to use the latest advancements in SCM.

  • 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 / 5 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 / 5 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 / 5 months ago
