Installation

Install from crates.io (Recommended)

cargo install cargo-fresh

or

# Faster installation using pre-compiled binaries
cargo binstall cargo-fresh

Note: cargo binstall provides faster installation by downloading pre-compiled binaries instead of compiling from source. If you don't have cargo binstall installed, cargo-fresh will automatically install it for you when needed.

Install from source

# Clone the repository
git clone https://github.com/jenkinpan/cargo-fresh.git
cd cargo-fresh

# Build and install
cargo install --path .

Install from GitHub

cargo install --git https://github.com/jenkinpan/cargo-fresh.git

Language Support

The tool automatically detects your system language and displays the interface accordingly:

• Chinese Environment: Automatically displays Chinese interface
• English Environment: Automatically displays English interface
• Language Detection: Based on system environment variables (LANG, LC_ALL, LC_CTYPE)

You can also manually override the language by setting environment variables:

# Force English interface
LANG=en_US.UTF-8 cargo fresh

# Force Chinese interface  
LANG=zh_CN.UTF-8 cargo fresh

Shell Completion Troubleshooting

Common Issues

Completion not working

If shell completion is not working, try the following:

1. Verify completion installation:

   # Check if completion files exist
   ls ~/.zsh/completions/_cargo-fresh  # For zsh
   ls ~/.local/share/bash-completion/completions/cargo-fresh  # For bash
   

2. Reload shell configuration:

   # For zsh
   source ~/.zshrc
   
   # For bash
   source ~/.bashrc
   
   # For fish
   # Restart fish shell
   

3. Regenerate completion files:

   # Generate fresh completion files
   cargo-fresh completion zsh > ~/.zsh/completions/_cargo-fresh
   cargo-fresh completion bash > ~/.local/share/bash-completion/completions/cargo-fresh
   

Missing options in completion

If you notice missing options in completion:

1. Update cargo-fresh:

   cargo install --force cargo-fresh
   

2. Regenerate completion files:

   cargo-fresh completion zsh > ~/.zsh/completions/_cargo-fresh
   

3. Verify completion includes new options:

   grep -E "(batch|filter)" ~/.zsh/completions/_cargo-fresh
   

Cargo fresh subcommand completion

For cargo fresh subcommand completion:

1. Generate cargo fresh completion:

   cargo-fresh completion zsh --cargo-fresh > ~/.zsh/completions/_cargo
   

2. Verify cargo completion:

   cargo <TAB>  # Should show 'fresh' as a subcommand
   cargo fresh <TAB>  # Should show all fresh options
