v0.1.3

This release marks the first official version of Nushell Alias Converter, a tool for converting Bash aliases into Nushell aliases. The project is primarily for educational purposes, allowing exploration of Tree-sitter, Rust, and Nushell parsing. However, it offers practical utility for those migrating their Bash aliases to Nushell!

Features

• Convert Bash Aliases to Nushell: The core functionality converts .bash_aliases to a Nushell-compatible format and outputs it as a .nu file.

• Seamless Nushell Integration: The tool regenerates the converted alias file at the start of each Nushell session, ensuring your environment remains in sync with any updates to your Bash aliases.

• Alias Ignoring: Customize which aliases are excluded from the conversion using a .aliasignore file. You can ignore aliases by name or by the command they run.

  Example .aliasignore file:

  ls
  !htop
  

🛠 Installation

Install the converter via Cargo:

cargo install nu-alias-converter

Usage

To convert your Bash aliases to Nushell, run:

nu-alias-converter .bash_aliases

For Nushell integration, add the following to your env.nu file:

nu-alias-converter ~/.bash_aliases -o $"($nu.default-config-dir)/bash-aliases.nu" | ignore

Then, source it in your config.nu:

source bash-aliases.nu

Error Handling and Comments

• Invalid or unrecognized aliases are commented out, along with information on the parsing error, so you can manually adjust them if needed.

Performance

• Parallelized Conversion: Using Rayon, the tool converts even large alias files quickly, improving performance dramatically (tested with a 28,888-line alias file).

What's Next?

• Support for handling multiple files in a directory.
• Improved handling for Zsh and Fish alias scripts.
• Enhancements for recursive alias expansion (expand_aliases and shopt -s expand_aliases).

This release is the first step towards making the migration between Bash and Nushell easier, while also serving as a learning platform for better parsing and Rust development practices.
