v1.2.0 — History, alignment, clickable UI, and 18 bug fixes

[1.2.0] — 2026-05-20

Added

• History persistence system — side sessions saved to ~/.local/share/opencode-sidechat/history.json (50-entry FIFO)
• History viewer — Alt+H toggles history list with date-grouped entries; click to view read-only transcript
• Inline tool-call rendering — collapsible one-liners (emoji + tool name + title + status + duration) expandable to show params and truncated output
• Panel position config — position option in sidechat.jsonc: "bottom-right" (default), "bottom-left", "top-left", "top-right"
• All footer items clickable — Clear, Thinking, Model, History, Back, and Delete now respond to mouse clicks
• Delete keybind — Alt+D deletes the currently viewed history entry (replaces non-functional Del)
• Empty <text> placeholders replaced with non-breaking spaces to preserve layout

Fixed

• Session destroyed on panel toggle close — now preserved across open/close cycles; only explicit Alt+C or plugin dispose destroys it
• Session leak on rapid Alt+C spam — added clearing guard flag preventing concurrent clear execution
• Duplicate history entries on repeated toggle — saveEntry now updates in-place by session ID and preserves original created timestamp
• [object Object] instead of typed message — ContentChangeEvent was an empty object; switched to reading .value from the input ref directly
• Input not growing with new lines — fixed by the same ContentChangeEvent fix; textarea now correctly counts \n for height
• Panel height frozen on terminal resize — terminalHeight and panelMaxHeight converted from const to createMemo() for reactivity
• Theme frozen on swap — theme converted to createMemo() so it reacts to theme changes
• History selector unresponsive — onMouseDown moved from <text> (not handled by OpenTUI) to parent <box>
• Input handling — reverted multi-line textarea to single-line <input> for reliable Enter-to-send behavior
• History entry selection on click — changed from non-functional onClick to onMouseDown on <box>
• Session re-open after close — sessionInitPromise now reset on session destroy so next open creates a fresh session
• All as any casts in tool-call state processing — replaced with proper RichToolState type with single boundary assertion
• inputValue not reactive — converted from mutable let to Solid createSignal
• Stale historyMode, historyEntries, selectedHistoryId fields in SideDialogState type — removed (managed as separate signals)
• provider field always empty in history entries — removed unused parameter and field from HistoryEntry
• History file I/O blocking TUI — loadHistory, saveEntry, deleteEntry migrated from fs.*Sync to fs.promises
• Empty catch {} in getAvailableToolIDs — now logs console.warn
• Default model tied to one provider — changed from "opencode/deepseek-v4-flash-free" to null
• renderThinking return typed as any — changed to explicit JSX.Element
• Magic number 6 in history title truncation — extracted to named HISTORY_TITLE_PADDING constant
• Cached tool IDs never invalidated — cleared on handleClear to reflect runtime tool changes
• History footer displayed alt+h instead of Alt+H — now uses formatKeybind() consistently
• History footer showed hardcoded "Del" — now uses formatKeybind(deleteKeybind) matching actual keybind

Changed

• SideChat.tsx reduced from 758 to 507 lines — extracted RenderMarkdown, renderInlineMarkdown, searchSpecialChar to new Markdown.tsx; extracted RenderHistoryDetail and formatTime to new HistoryDetail.tsx
• All keybind labels use formatKeybind() for consistent display formatting
• handleToggleHistory no longer loads history when exiting history mode (correct direction check)
• handleClear now invalidates cachedToolIDs and cachedPromptResult
• OverlayState widened — onSelectHistoryEntry accepts string | undefined for deselection

Config

• New position option — "bottom-right" / "bottom-left" / "top-left" / "top-right"
• Default model changed to null (was "opencode/deepseek-v4-flash-free")
