# Dingo Configuration File
# This file controls the behavior of the Dingo transpiler

[features]
# Error propagation operator syntax
# Valid values: "question" (?), "bang" (!), "try" (try keyword)
error_propagation_syntax = "question"

# Reuse "err" variable instead of generating __err0, __err1, etc.
# When true: Generates cleaner code with reused "err" variable (more idiomatic)
# When false: Generates unique names like __err0, __err1 (safer, avoids shadowing)
# Default: true
reuse_err_variable = true

# Nil safety checks for pattern destructuring in sum types
# Valid values: "off", "on", "debug"
# - off: No nil checks (trust constructors, maximum performance)
# - on: Always check with runtime panic (safe, recommended)
# - debug: Check only when DINGO_DEBUG environment variable is set
# Default: "on"
nil_safety_checks = "on"

[features.result_type]
# Enable Result<T, E> type for error handling
# Default: true
enabled = true

# Go interoperability mode for (T, error) returns
# Valid values: "opt-in", "auto", "disabled"
# - "opt-in": Requires explicit Result.FromGo() wrapper (safe, recommended)
#   Example: let user = Result.FromGo(fetchUser(id))
# - "auto": Automatically wraps (T, error) → Result<T, E>
#   Example: let user = fetchUser(id)  // Auto-wrapped to Result
# - "disabled": No Go interop, pure Dingo types only
# Default: "opt-in"
go_interop = "opt-in"

[features.option_type]
# Enable Option<T> type for null safety
# Default: true
enabled = true

# Go interoperability mode for pointer types (*T)
# Valid values: "opt-in", "auto", "disabled"
# - "opt-in": Requires explicit Option.FromPtr() wrapper (safe, recommended)
#   Example: let user = Option.FromPtr(findUser(id))
# - "auto": Automatically wraps *T → Option<T>
#   Example: let user = findUser(id)  // Auto-wrapped to Option
# - "disabled": No Go interop, pure Dingo types only
# Default: "opt-in"
go_interop = "opt-in"

[sourcemaps]
# Enable source map generation for better debugging and IDE support
enabled = true

# Source map output format
# Valid values: "inline", "separate", "both", "none"
# - inline: Embeds source maps as comments in .go files
# - separate: Writes .go.map files
# - both: Generates both inline and separate files
# - none: Disables source maps
format = "inline"
