OpenCode — IntelliJ Integration

OpenCode has no native IntelliJ plugin; it runs inside IntelliJ's built-in terminal, which gives you a split-pane AI assistant alongside your editor.

Setup

1. Install OpenCode CLI

npm install -g opencode-ai

2. Authenticate

opencode auth login https://ai.camer.digital/opencode

Browser opens for authentication. Login, return to terminal, select model.

3. Open in the IntelliJ Terminal

• Open IntelliJ
• Open the terminal: Alt+F12
• Navigate to your project: cd /path/to/project
• Run: opencode

Configuration

Set IntelliJ as the editor for OpenCode diffs. Add to your shell profile (~/.bashrc or ~/.zshrc):

macOS:

export EDITOR="idea --wait"

Linux:

export EDITOR="/opt/idea/bin/idea.sh --wait"

Windows (PowerShell):

$env:EDITOR = "idea64 --wait"

Usage

Basic Commands

Initialize project context:

/init

Reference a file:

Explain @src/main/kotlin/UserService.kt

Run a shell command from within OpenCode:

!./gradlew test

Split-Pane Workflow

1. Open terminal (Alt+F12)
2. Right-click the terminal tab
3. Select Split Right
4. Run OpenCode in one pane, keep your shell in the other

Troubleshooting

opencode command not found:

export PATH="$HOME/.local/bin:$PATH"
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
