Overview ¶
Package config resolves the diff render settings for a session, layering the JJ_DIFF_* environment variables over a set of built-in defaults.

Types ¶
type Config ¶
type Config struct {
ViewMode ViewModeType
ShowWhitespace bool
ShowLineNumbers bool
TabWidth int
WordLevelDiff bool
}
Config is the fully resolved settings for a session. Every field has a usable zero-value replacement from DefaultConfig, so callers never build one by hand.
func DefaultConfig ¶
func DefaultConfig() Config
DefaultConfig returns the settings that apply when no environment variable is set: unified layout, line numbers on, whitespace and word-level diff off, tabs four columns wide.
func LoadConfig ¶
func LoadConfig() Config
LoadConfig reads the JJ_DIFF_* environment variables over DefaultConfig. A value that cannot be understood is ignored rather than reported, so the default survives and startup never fails on a typo. Booleans are true only for "1", "true", "yes", or "on", and JJ_DIFF_TAB_WIDTH is honored for 1 to 16.
func (Config) ToRenderOptions ¶
func (c Config) ToRenderOptions() RenderOptions
ToRenderOptions drops the layout choice and keeps the fields that affect a single rendered line.
type RenderOptions ¶
type RenderOptions struct {
ShowWhitespace bool
ShowLineNumbers bool
TabWidth int
WordLevelDiff bool
}
RenderOptions carries the per-line rendering settings without the layout choice, so a renderer can be handed only what affects a single line of output.
type ViewModeType ¶
type ViewModeType string
ViewModeType selects how the two sides of a diff are laid out.
const ( ViewModeUnified ViewModeType = "unified" ViewModeSideBySide ViewModeType = "side-by-side" )
Diff layouts. The string values are also what JJ_DIFF_VIEW_MODE accepts, which is why they are spelled as user-facing words rather than as an int enum.
