📦 Installation

From crates.io (Recommended)

cargo install devtool

Make sure ~/.cargo/bin is in your PATH environment variable.

From source

git clone https://github.com/jenkinpan/devtool-rs.git
cd devtool-rs
cargo build --release
cargo install --path .

🚀 Usage

Basic Usage

Simply run devtool in your terminal to start the update process:

devtool

This is equivalent to running devtool update.

Parallel Execution (Default in v0.7.0)

Parallel execution is now the default mode for faster updates:

# Default parallel execution with 3 concurrent jobs
devtool

# Control the number of concurrent jobs
devtool --jobs 5

# Sequential execution (override parallel mode)
devtool --sequential

# Parallel execution with dry run
devtool --jobs 3 --dry-run

Performance Benefits:

• Up to 10x faster execution with parallel mode (default)
• Configurable concurrency with --jobs parameter (default: 3)
• Choose between parallel (default) or sequential execution
• Intelligent dependency management
• Maintains all safety features of sequential mode

Command Line Options

Customize devtool behavior with these options:

Option	Short	Description
--dry-run	-n	Show steps that would be executed without actually running them
--verbose	-v	Print detailed output for each step during execution
--version	-V	Show version information
--keep-logs		Keep log files for each step, stored in unified cache directory by default
--no-banner		Don't show startup banner
--compact		Use more compact output format for non-interactive environments
--parallel		Execute update steps in parallel (default)
--sequential		Execute update steps sequentially (override parallel mode)
--jobs		Number of concurrent jobs for parallel execution (default: 3)
--no-color		Disable colored output
--help	-h	Show help information

📊 Upgrade Details Tracking

devtool now provides detailed upgrade tracking, showing exactly what was upgraded with before/after version information:

Upgrade Detail Display

When upgrades occur, devtool shows detailed information about what was changed:

🎉 更新完成：2025-10-18 14:00:30 (耗时: 12秒)
✅ 已更新：Homebrew, Rustup
ℹ️ 无更新应用。

📋 升级详情：
Homebrew：升级软件包
  - git: 2.45.0 → 2.45.1
  - node: 20.10.0 → 20.11.0

📁 Log Storage System

devtool provides a comprehensive log storage system for easy troubleshooting and debugging:

Unified Log Storage

All log files are stored in a unified location:

• macOS: ~/Library/Caches/devtool/
• Linux: ~/.cache/devtool/

Directory Structure

Logs are organized by tool with timestamped directories:

~/Library/Caches/devtool/
├── homebrew/
│   ├── 1761008090/
│   │   ├── brew_cleanup.log
│   │   ├── brew_detailed_debug.log
│   │   ├── brew_outdated.log
│   │   ├── brew_update.log
│   │   ├── brew_upgrade.log
│   │   └── outdated_packages.json
│   └── latest -> 1761008090/
├── rustup/
│   ├── 1761008078/
│   │   └── rustup_update.log
│   └── latest -> 1761008078/
├── mise/
│   ├── 1761008076/
│   │   └── mise_up.log
│   └── latest -> 1761008076/
└── feedback/
    └── devtool_feedback_*.md

Log File Types

Each tool generates specific log files:

• Homebrew:

  • brew_update.log: Homebrew update output
  • brew_upgrade.log: Homebrew upgrade output
  • brew_cleanup.log: Homebrew cleanup output
  • brew_outdated.log: Outdated packages detection
  • brew_detailed_debug.log: Detailed debugging information
  • outdated_packages.json: JSON format of outdated packages

• Rustup:

  • rustup_update.log: Rustup update output

• Mise:

  • mise_up.log: Mise update output

Using Logs for Troubleshooting

1. Access latest logs: Use the latest symlink for the most recent execution

   ls ~/Library/Caches/devtool/homebrew/latest/
   

2. View specific log files: Check individual log files for detailed information

   cat ~/Library/Caches/devtool/homebrew/latest/brew_detailed_debug.log
   

3. Historical logs: Browse timestamped directories for previous executions

   ls ~/Library/Caches/devtool/homebrew/
   

Enabling Log Storage

Use the --keep-logs flag to enable log storage:

devtool update --keep-logs

This will save all log files to the unified cache directory for later analysis.

# Add to ~/.bashrc
source <(devtool completion bash)

Zsh:

# Add to ~/.zshrc
source <(devtool completion zsh)

Fish:

# Add to ~/.config/fish/config.fish
devtool completion fish | source

Nushell:

# Add to your config.nu
use ~/.config/nushell/completions/devtool-completions.nu *

🔧 Troubleshooting

Command not found

If you get command not found: devtool after installation:

# Check if ~/.cargo/bin is in your PATH
echo $PATH

# Add to your shell profile (e.g., ~/.bashrc, ~/.zshrc)
export PATH="$HOME/.cargo/bin:$PATH"

# Reload your shell configuration
source ~/.bashrc  # or source ~/.zshrc

Permission errors

If you encounter permission errors:

# Make sure the binary is executable (Unix/Linux/macOS)
chmod +x ~/.cargo/bin/devtool

# On macOS, if blocked by Gatekeeper:
xattr -d com.apple.quarantine ~/.cargo/bin/devtool

No tools detected

devtool only updates tools that are already installed. To get started:

• Install Homebrew (macOS/Linux)
• Install Rustup (all platforms)
• Install Mise (all platforms)

Updates fail

If updates fail consistently:

1. Try running the tool's update command manually to see the actual error
2. Check your internet connection
3. Verify you have sufficient disk space
4. Run with --verbose flag for detailed output: devtool --verbose
5. Check log files in ~/.cache/devtool/logs/ for detailed error messages

Language/locale issues

Force English output if automatic language detection doesn't work:

LANG=en_US.UTF-8 devtool

💡 Tips & Tricks

Create an alias

Add to your shell profile for quick access:

alias dup='devtool'
alias update-dev='devtool'

Automated updates

Using cron (Linux/macOS):

# Edit crontab
crontab -e

# Add this line to run daily at 9 AM
0 9 * * * /home/username/.cargo/bin/devtool

Using launchd (macOS):

Create ~/Library/LaunchAgents/com.devtool.update.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.devtool.update</string>
    <key>ProgramArguments</key>
    <array>
        <string>/Users/yourname/.cargo/bin/devtool</string>
    </array>
    <key>StartCalendarInterval</key>
    <dict>
        <key>Hour</key>
        <integer>9</integer>
        <key>Minute</key>
        <integer>0</integer>
    </dict>
</dict>
</plist>

Then load it: launchctl load ~/Library/LaunchAgents/com.devtool.update.plist

Integration with other tools

In Makefiles:

.PHONY: update-tools
update-tools:
	devtool

.PHONY: dev-setup
dev-setup: update-tools
	npm install
	bundle install

In scripts:

#!/bin/bash
# Safe update script
if devtool --dry-run; then
    echo "Dry run successful, proceeding..."
    devtool
else
    echo "Dry run failed, skipping update"
    exit 1
fi

Notifications on completion

macOS:

devtool && osascript -e 'display notification "Updates completed" with title "devtool"'

Linux (with notify-send):

devtool && notify-send "devtool" "Updates completed"
