Module config 

Engine configuration via jpx.toml.

Provides declarative configuration for the jpx engine, supporting function filtering, query libraries, and engine settings. Configuration is loaded from multiple sources with layered overrides:

1. Defaults – EngineConfig::default() (strict=false, all functions enabled)
2. Global – ~/.config/jpx/jpx.toml (via dirs::config_dir())
3. Project-local – Walk up from CWD looking for jpx.toml
4. Env override – $JPX_CONFIG points to a specific file
5. Programmatic – CLI flags, MCP args, builder calls

Example

[engine]
strict = false

[functions]
disabled_categories = ["geo", "phonetic"]
disabled_functions = ["env"]

[queries]
libraries = ["~/.config/jpx/common.jpx"]

[queries.inline]
active-users = { expression = "users[?active].name", description = "Get active user names" }
