Compatibility Features

Bash 3.2 Compatibility

The installer is specifically designed to work with bash 3.2 (macOS default):

✅ No mapfile usage - Uses while-read loops instead
✅ No process substitution issues - Uses temp files for compatibility
✅ POSIX-compliant - Avoids bash 4+ specific features
✅ Array operations - Uses bash 3.2 compatible syntax

Bash 5.x Compatibility (Fixed in v1.1.0)

The installer now works correctly with bash 5.x (Ubuntu 24.04, modern Linux):

✅ set -e compatible arithmetic - Uses variable=$((variable + 1)) instead of ((variable++))
✅ No premature exits - Fixed issue where counters starting at 0 caused script exit
✅ Tested on bash 5.2.21 - Fully compatible with Ubuntu 24.04 and newer systems

What was fixed:

  • Changed all arithmetic increment operations from ((variable++)) to variable=$((variable + 1))
  • This prevents set -e from triggering exit when variables start at 0
  • Maintains error detection while ensuring compatibility across all bash versions

Cross-Platform Features

✅ Platform detection - Automatically detects macOS/Linux/Windows
✅ Color support detection - Disables colors on unsupported terminals
✅ Path handling - Works with Unix and Windows paths (tilde expansion, backslash conversion)
✅ Line endings - Handles both LF and CRLF
✅ Custom install directories - Supports local, global, and custom installation paths

Testing Your System

Run the compatibility test to verify your system:

# Download and run the test
curl -fsSL https://raw.githubusercontent.com/darrenhinde/OpenAgentsControl/main/scripts/tests/test-compatibility.sh | bash

Or manually:

# Clone the repo
git clone https://github.com/darrenhinde/OpenAgentsControl.git
cd OpenAgentsControl

# Run the test
bash scripts/tests/test-compatibility.sh

The test checks:

  • ✅ Bash version (3.2+)
  • ✅ Required dependencies (curl, jq)
  • ✅ Script syntax
  • ✅ Argument parsing
  • ✅ Array operations
  • ✅ File operations
  • ✅ Network connectivity

Troubleshooting

Script exits immediately on Ubuntu 24.04 / bash 5.x

Cause: Older versions of the installer had a set -e compatibility issue with bash 5.x
Status: ✅ FIXED in v1.1.0
Solution: Update to the latest installer:

curl -fsSL https://raw.githubusercontent.com/darrenhinde/OpenAgentsControl/main/install.sh > install.sh
bash install.sh developer

Technical Details:

  • Issue: ((variable++)) returns 0 when variable is 0, triggering set -e exit in bash 5.x
  • Fix: Changed to variable=$((variable + 1)) which is safe with set -e
  • Affected: Ubuntu 24.04 (bash 5.2.21) and other modern Linux distributions
  • All arithmetic operations now use the safe pattern

"mapfile: command not found"

Cause: Using bash version < 4.0
Solution: This should be fixed in the latest version. Update the installer:

curl -fsSL https://raw.githubusercontent.com/darrenhinde/OpenAgentsControl/main/install.sh > install.sh
bash install.sh developer

"curl: command not found"

Cause: curl is not installed
Solution:

# macOS
brew install curl

# Ubuntu/Debian
sudo apt-get install curl

# Fedora/RHEL
sudo dnf install curl

# Windows: Install Git for Windows (includes curl)

"jq: command not found"

Cause: jq is not installed
Solution:

# macOS
brew install jq

# Ubuntu/Debian
sudo apt-get install jq

# Fedora/RHEL
sudo dnf install jq

# Windows Git Bash
curl -L -o /usr/bin/jq.exe https://github.com/stedolan/jq/releases/latest/download/jq-win64.exe

Colors not displaying correctly (Windows)

Cause: Terminal doesn't support ANSI colors
Solution: Use Windows Terminal, Git Bash, or WSL instead of cmd.exe

"Permission denied" errors

Cause: Insufficient permissions
Solution:

# Don't use sudo with the installer
# It installs to .opencode/ in current directory

# If you need to install globally:
sudo bash install.sh core

Script fails on Windows PowerShell

Cause: PowerShell can't run bash scripts directly
Solution: Use Git Bash or WSL:

# Download first
Invoke-WebRequest -Uri "https://raw.githubusercontent.com/darrenhinde/OpenAgentsControl/main/install.sh" -OutFile "install.sh"

# Run with Git Bash
& "C:\Program Files\Git\bin\bash.exe" install.sh

Known Limitations

Windows cmd.exe

❌ Not Supported - Use Git Bash or WSL instead

Bash < 3.2

❌ Not Supported - Upgrade bash or use a different system

No Internet Connection

❌ Not Supported - Installer requires internet to download components
Workaround: Use manual installation (clone repo and copy files)

Manual Installation (No Internet)

If you can't use the installer:

# 1. Clone or download the repository
git clone https://github.com/darrenhinde/OpenAgentsControl.git
cd OpenAgentsControl

# 2. Copy to OpenCode directory
mkdir -p ~/.opencode
cp -r .opencode/agent ~/.opencode/
cp -r .opencode/command ~/.opencode/
cp -r .opencode/context ~/.opencode/
cp -r .opencode/tool ~/.opencode/
cp -r .opencode/plugin ~/.opencode/

# 3. Configure environment
cp env.example .env
# Edit .env with your settings

Getting Help

If you encounter issues:

  1. Run the compatibility test:

    curl -fsSL https://raw.githubusercontent.com/darrenhinde/OpenAgentsControl/main/scripts/tests/test-compatibility.sh | bash

  2. Check your bash version:

    bash --version

  3. Verify dependencies:

    curl --version
jq --version

  4. Report issues:

Summary

✅ macOS - Works out of the box (bash 3.2+)
✅ Linux - Works on all major distributions
✅ Windows - Use Git Bash or WSL
✅ Bash 3.2+ - Fully compatible
✅ Cross-platform - Same commands everywhere

The installer is designed to "just work" on any modern system with bash 3.2+.
