v0.5.0

Breaking

• @cursor renamed to @option_index in option-based prompts (affects subclasses)
• Signal handlers moved into Clack.setup! (called automatically on first prompt)

Changed

• Extracted SelectionManager module shared by Multiselect, AutocompleteMultiselect, GroupMultiselect
• SIGWINCH handler is now async-signal-safe
• Multiselect raises ArgumentError on initial_value: (must use initial_values:)

Added

• Clack.setup! / Clack.setup? for explicit signal handler installation
• KeyQueue in Clack::Testing for deterministic key simulation
• New specs for SelectionManager, OptionsHelper, Prompt internals, CI mode
• README rewritten with badges, before/after comparison, reorganized sections

v0.4.6

Fixed

• Settings.printable? now accepts combining characters and multi-codepoint grapheme clusters (accented letters, emoji)
• Signal handlers use write_nonblock instead of print for async safety
• S_STEP_ERROR ASCII fallback changed from x to ! (was identical to S_STEP_CANCEL)
• CI mode validation warnings now print to stderr instead of stdout

Changed

• Colors, Cursor, and Symbols ANSI detection unified through Environment.colors_supported?
• Extracted build_final_frame template into Core::Prompt with final_display hook (11 prompt classes simplified)
• Date prompt: consolidated duplicated segment logic into update_segment

v0.4.5

Fixed

• Autocomplete and AutocompleteMultiselect now route all printable characters to the search field first, fixing vim aliases (j/k/h/l) hijacking text input
• AutocompleteMultiselect no longer intercepts a/i keys as shortcuts — they conflicted with typing in the search field
• AutocompleteMultiselect#toggle_current now respects :disabled options, matching Multiselect behavior

Changed

• AutocompleteMultiselect internals aligned with Multiselect: @selected naming, submit override pattern, keyboard_hints method, build_frame validation rendering, initial_values: [] default

Added

• examples/showcase.rb — full-featured demo with branching, autocomplete, date, range, group multiselect, tasks
• examples/migration_from_tty_prompt.rb — side-by-side migration guide from tty-prompt
• README: "Why Clack?" with zero-dependencies callout, quick reference table, TL;DR tagline, vim key notes on autocomplete sections

v0.4.4

Fixed

• INT handler is now exception-safe (catches IOError/SystemCallError when output is unavailable)

Added

• SIGTERM handler restores cursor on graceful kill, matching INT handler behavior
• Cursor.enabled? now respects FORCE_COLOR environment variable, consistent with Colors module
• Spinner#message returns self for method chaining

Changed

• Task and TaskResult now use Data.define instead of Struct.new (Ruby 3.2+ idiom)

v0.4.3

Fixed

• Multiselect variants now ignore initial_values that don't match any option (prevents phantom values in return)
• SIGWINCH handler now uses .dup for safe array iteration inside signal trap
• GroupMultiselect propagates :hint into flat items so hints actually render

Changed

• AutocompleteMultiselect final frame now shows selected labels instead of "N items selected", matching Multiselect behavior
• Removed dead @mutex from Testing module
• Removed unused raw: parameter from TaskLog and TaskLogGroup message methods

v0.4.2

Fixed

• GroupMultiselect now preserves :hint on options (was silently dropped during normalization)
• GroupMultiselect renders hints on active options, matching Select behavior
• Spinner no longer raises when finished in timer mode before the animation thread starts
• YARD docs: corrected selectable_groups default from true to false

Changed

• Range prompt now accepts initial_value: for consistency with all other prompts (default: still works)
• README: corrected Range example to use initial_value: and tab completion description

v0.1.4 - Warning Validation

Added

• Warning validation: Validators can return Clack::Warning.new(message) for soft failures that allow user confirmation
• Built-in warning validators: Validators.file_exists_warning and Validators.as_warning(validator)
• Test coverage for warning state machine and multiselect keyboard shortcuts

Changed

• Simplified Multiselect implementation by using base class warning/error handling (37 lines → 12 lines)
• Unified validation message rendering across all prompt types

v0.1.1

What's Changed

• Terminal safety and input handling fixes by @swhitt in #7
• Release 0.1.1 by @swhitt in #8
