:cherry_blossom: A command-line fuzzy finder

Pros of fzf

  • More versatile, can be used for general-purpose fuzzy finding beyond just command-line snippets
  • Highly customizable with extensive options for appearance and behavior
  • Faster performance, especially with large datasets

Cons of fzf

  • Steeper learning curve, requires more setup for specific use cases
  • Less focused on command-line snippet management compared to navi

Code Comparison

fzf:

find * -type f | fzf > selected

navi:

navi --query "git commit"

Summary

fzf is a powerful and flexible fuzzy finder that can be used for various purposes, including file searching, command history browsing, and more. It offers extensive customization options and excellent performance.

navi, on the other hand, is specifically designed for managing and accessing command-line snippets. It provides a more focused and user-friendly experience for this particular use case, with features like cheatsheet management and interactive prompts.

While fzf excels in versatility and speed, navi offers a more streamlined experience for command snippet management. The choice between the two depends on the user's specific needs and preferences.

Cons of ripgrep

  • Limited to text search functionality, lacks interactive features
  • Requires command-line proficiency for effective use
  • Does not provide a cheatsheet or quick reference for common commands

Code comparison

ripgrep:

rg "pattern" /path/to/search
rg -i "case insensitive" ./src
rg -t py "python specific" ./project

navi:

navi
navi --query "git commit"
navi --tldr tar

Summary

ripgrep is a powerful, fast text search tool optimized for code repositories, while navi is an interactive cheatsheet manager for command-line interfaces. ripgrep excels in speed and efficiency for searching large codebases, whereas navi focuses on providing an interactive way to learn and use command-line tools. The choice between the two depends on the specific use case: ripgrep for rapid text searches, and navi for command discovery and learning.

A simple, fast and user-friendly alternative to 'find'

Pros of fd

  • Faster and more efficient file searching compared to traditional find command
  • User-friendly syntax with smart case sensitivity and regex support
  • Cross-platform compatibility (Linux, macOS, Windows)

Cons of fd

  • Limited to file searching functionality
  • Lacks the interactive cheat sheet and command suggestion features
  • May require additional tools for more complex operations

Code Comparison

fd:

fd -e txt
fd '^foo.*bar' /path/to/search

navi:

navi
navi --query 'git commit'

Key Differences

navi is an interactive cheat sheet tool for command-line interfaces, while fd is a fast and user-friendly alternative to the find command. navi focuses on providing a searchable repository of commands and snippets, whereas fd specializes in efficient file searching.

navi offers a more comprehensive solution for command discovery and learning, making it particularly useful for beginners or those working with complex command-line tools. fd, on the other hand, excels in quickly locating files and directories based on various criteria.

While both tools aim to improve command-line productivity, they serve different purposes and can be complementary in a user's toolkit. fd's simplicity and speed make it ideal for file operations, while navi's interactive nature and extensive command database provide a broader range of assistance for command-line tasks.

📚 Collaborative cheatsheets for console commands

Pros of tldr

  • Larger community and more contributors, resulting in a wider range of command examples
  • Simpler and more straightforward interface for quick command lookups
  • Available in multiple languages, making it accessible to a global audience

Cons of tldr

  • Limited to static, pre-defined command examples
  • Lacks interactive features for command customization and execution
  • No built-in search functionality for finding specific commands

Code Comparison

tldr example (command lookup):

tldr tar

navi example (interactive command search and execution):

navi --query "tar"

Summary

tldr is a straightforward command-line tool that provides concise examples for various commands, making it ideal for quick reference. It benefits from a large community and multilingual support. However, it lacks interactive features and customization options.

navi, on the other hand, offers an interactive interface with advanced search capabilities and the ability to execute commands directly. It allows for more flexibility in command usage but may have a steeper learning curve and a smaller community compared to tldr.

Both tools serve the purpose of helping users navigate command-line interfaces, but they cater to different user preferences and use cases.

  • Easier to create and edit cheatsheets directly

Cons of cheat

  • Less interactive and feature-rich interface
  • Limited search capabilities compared to navi
  • Lacks advanced features like variable substitution and shell integration

Code comparison

navi allows you to browse through cheatsheets (that you may write yourself or download from maintainers) and execute commands. Suggested values for arguments are dynamically displayed in a list.

Pros

  • it will spare you from knowing CLIs by heart
  • it will spare you from copy-pasting output from intermediate commands
  • it will make you type less
  • it will teach you new one-liners

It uses fzf, skim, or Alfred under the hood and it can be either used as a command or as a shell widget (à la Ctrl-R).

    • pros: you have access to all possible subcommands and flags
  • as a shell widget for the terminal
    • pros: the shell history is correctly populated (i.e. with the actual command you ran instead of navi) and you can edit the command as you wish before executing it
  • as a Tmux widget
    • pros: you can use your cheatsheets in any command-line app even in SSH sessions
  • as aliases
  • as a shell scripting tool
  • as an Alfred workflow
