Shell Completions

The completions plugin adds a completions command for Bash/Zsh/Fish.

Quick install patterns:

# Bash (current session)
source <(ai-img completions bash)

# Zsh (save file)
mkdir -p ~/.zsh/completions
ai-img completions zsh > ~/.zsh/completions/_ai-img

# Fish (save file)
ai-img completions fish > ~/.config/fish/completions/ai-img.fish

Providers

Supported providers: openai, google, fal.

Credential resolution order is:

• Environment variables
• Config secrets (aiImg.secrets.<provider>)

Environment variable names:

• OpenAI: OPENAI_API_KEY
• Google: GOOGLE_API_KEY, GEMINI_API_KEY, GOOGLE_GENERATIVE_AI_API_KEY
• Fal: FAL_API_KEY

Runtime Config

Config is loaded from these sources (deep merged, later overrides earlier):

• ~/.config/ai-img/config.json
• .ai-imgrc
• .ai-imgrc.json
• .ai-imgrc.local.json

Runtime precedence is:

• CLI flags
• Project config
• User config
• Built-in defaults

config init/set/unset defaults to --target user. Use --target project to write local project config.

For preview mode specifically, precedence is:

• --image-mode flag
• aiImg.preview.mode config
• default auto

Config Schema

Terminal Preview Notes

• Preview mode values: off, auto, on
• auto is best-effort and non-fatal when rendering is unavailable
• on is strict and fails fast before provider API calls when preview is unsupported
• Default thumbnail width is 32 columns; only width is set so aspect ratio is preserved
• Current protocol support is Kitty-compatible terminals (for example Kitty, Ghostty)
• aiImg.schemaVersion defaults to 1 during config load when omitted

IDE Autocomplete via JSON Schema

The config schema is generated from Zod and published as ai-img.schema.json.

Generate/update it:

bun run generate:schema

Check for drift:

bun run generate:schema:check

Use it in your config file:

{
  "$schema": "./ai-img.schema.json",
  "aiImg": {
    "schemaVersion": 1
  }
}

Scripts

bun run dev
bun run build
bun run typecheck
bun run generate:schema
bun run generate:schema:check
