That is too many steps for a daily action. +3. **Save the response to a file** -- there is no export mechanism; users must manually copy-paste into a file. +4. **Search within the response** -- large JSON payloads are unnavigable without find. The sidebar already has `/` search for filtering items; the response panel has nothing equivalent. + +These are the last Phase 1 features. Completing them makes Perseus viable for daily API development work. + +## Proposed Solution + +Four sub-features, ordered from simplest to most complex: + +### 1. Response Size Display + +Show the response body byte count alongside the existing status text in the response tab bar. + +- Capture `body_size_bytes: usize` on `ResponseData` by calling `response.bytes().await` in `src/http.rs`, measuring `.len()`, then converting to a UTF-8 string with `String::from_utf8_lossy()`. This preserves the true wire size even when the body is later pretty-printed. (Note: reqwest's `.bytes()` and `.text()` both consume the response -- you must use `.bytes()` and convert manually.) +- Add a `format_size(bytes: usize) -> String` helper (1024-based thresholds: B / KB / MB / GB, one decimal place above bytes). +- Extend the right-aligned status text in `render_response_tab_bar()` from `"200 OK (245ms)"` to `"200 OK (245ms) · 1.2 KB"`. +- At narrow widths (< 50 cols inner), hide the size to avoid overlapping the tab labels. +- Size is body-only, not headers. + +### 2. One-Key Copy Response Content + +Copy the currently visible tab content (body **or** headers) to the system clipboard with a single keystroke. + +| Mode | Key | Behavior | +|------|-----|----------| +| Navigation (response focused) | `c` | Copy current tab content, show toast | + +Users in Editing mode press Esc first to return to Navigation, then `c`. One extra keystroke is acceptable -- it avoids adding a parallel Ctrl-combo binding with terminal compatibility concerns. + +- If `response_tab == Body`, copy the formatted (pretty-printed) body text. +- If `response_tab == Headers`, copy the rendered header text. +- If no successful response exists, show toast "No response to copy". +- Reuse the existing `clipboard.set_text()` + `set_clipboard_toast()` pattern from `src/app.rs`. +- Toast message: `"Copied response body (1.2 KB)"` or `"Copied response headers"`. + +### 3. Save Response to File + +Save the current tab content (body or headers) to a user-specified file path. + +| Mode | Key | Behavior | +|------|-----|----------| +| Navigation (response focused) | `S` | Open file path input popup | + +Users in Editing mode press Esc first to return to Navigation, then `S`. This avoids `Ctrl+Shift+S`, which most terminals cannot distinguish from `Ctrl+S` (already bound to save-collection). + +**Popup design:** +- Center-screen popup matching the existing `SidebarPopup` visual pattern (bordered block with title "Save Response"). +- Reuse `TextInput` struct for path entry. +- Enter confirms and writes the file; Esc cancels. +- Paths are resolved relative to the CWD where Perseus was launched. +- Tilde expansion (`~/`) is supported via simple prefix replacement. +- If the path's parent directory does not exist, show an error toast. +- If the file already exists, overwrite silently (matches `curl -o` behavior). +- On success: toast `"Saved to (1.2 KB)"`. +- On error: toast `"Save failed: "`. + +**State:** +- Add `save_popup: Option` to `App`. +- Intercept keys early in `handle_key()` when `save_popup.is_some()` -- route to `handle_text_input()`. +- Render via a new `render_save_popup()` function in `src/ui/mod.rs`. + +### 4. Response Body Search + +Vim-style `/` search with incremental highlighting and match navigation. + +**Activation:** +- Press `/` while in Editing Normal mode on the response Body tab. +- A 1-row search bar appears at the bottom of the response content area (steals space from the content, does not overlay). +- Format: `/ query text here [Aa] 3/17` + - Left: search input with `/` prefix + - Right: case indicator (`Aa` = insensitive, `AA` = sensitive) and match count `current/total` + +**State machine integration (Option B -- boolean flag):** +- Add to `App`: + ```rust + pub struct ResponseSearch { + pub active: bool, // search input bar is visible and receiving keys + pub query: String, // persisted after Enter so n/N can use it + pub input: TextInput, // current input field + pub matches: Vec, // (line_index, byte_start, byte_end) + pub current_match: usize, // index into matches vec + pub case_sensitive: bool, // toggle state + } + ``` +- `response_search: ResponseSearch` on `App` (always present, `active` toggled). +- When `active == true`, `handle_editing_mode()` intercepts **all** keys before vim dispatch: + - Character keys go to `input`. + - After each keystroke, recompute matches against the raw body text (pre-wrap, post-format). + - Enter: confirm search -- set `active = false`, persist `query = input.text()`, keep highlights and `current_match`. + - Esc: cancel -- set `active = false`, clear `query`, clear matches and highlights. + - `Ctrl+I`: toggle `case_sensitive`, recompute matches. +- When `active == false` but `query` is non-empty, `n`/`N` in vim Normal mode navigate matches: + - Intercept `n`/`N` in `handle_editing_mode()` before vim dispatch. + - `n` advances `current_match` (wraps around). + - `N` moves backwards (wraps around). + - Auto-scroll to bring the current match into view. + +**Highlighting:** +- Matches are highlighted with `bg(Color::Yellow) + fg(Color::Black)`. +- The current match is highlighted with `bg(Color::LightRed) + fg(Color::Black)`. +- Highlighting is applied as a post-processing pass over `cache.lines` (the colorized `Vec>`) before word wrapping, by splitting spans at match boundaries and overriding styles. This preserves JSON syntax colors underneath for non-matching regions. +- The `ResponseBodyRenderCache` gains a `search_generation: u64` counter; when the search state changes, bump the generation to trigger a re-render of highlighted lines. + +**Search operates on the raw (unwrapped) body text.** Match byte offsets are mapped to line/column positions in the pre-wrap lines. The wrapping pass carries highlight styles through to wrapped output. + +**Edge cases:** +- Empty query on Enter: clears search state (same as Esc). +- No matches: show `0/0` in the search bar, no highlights. +- New response arrives: clear all search state (`query`, `matches`, `active`). +- Search only available on Body tab. `/` on Headers tab is a no-op. +- Very large responses: match computation is O(n) per keystroke. For responses > 1 MB, add debouncing if profiling shows > 50ms latency (not implemented upfront -- measure first). + +**Layout change:** +- `ResponseLayout::new()` accepts a `search_active: bool` parameter. +- When true, adds `Constraint::Length(1)` at the bottom of `content_area`, splitting it into `content_area` + `search_bar_area`. + +## Technical Considerations + +**Render cache invalidation:** +The response body render cache has two layers: colorized lines and wrapped lines. Search highlighting adds a third concern. Rather than adding a full third cache layer, use a `search_generation` counter. When search state changes (new query, new match index, search cleared), bump the counter. The render function checks `search_generation` against the cache's stored value to decide whether to re-apply highlights. Highlights are applied on top of cached colorized lines, producing highlighted lines that are then wrapped. + +**Performance for large responses:** +- Incremental search recomputes match positions on every keystroke. For typical API responses (< 100 KB), this is negligible. If profiling shows > 50ms latency on larger responses, add debouncing then. +- Highlight application iterates all matches and splits spans. For thousands of matches, this is O(matches * avg_spans_per_line). Acceptable for typical use. + +**Keybinding conflicts:** +- `c` in Navigation mode on Response panel: currently unused. Safe. +- `S` in Navigation mode on Response panel: currently unused. Safe. +- `/` in Editing Normal mode: not handled by `transition_read_only()`, falls through to `Nop`. Safe to intercept before vim dispatch. +- `n`/`N` in Editing Normal mode: not handled by `transition_read_only()`. Safe to intercept. +- `Ctrl+I` during search input: not used elsewhere in text input contexts. Safe. + +**`body_size_bytes` accuracy:** +Measuring size from `response.bytes().await` gives the decompressed wire size (reqwest decompresses gzip by default). This matches what Postman displays and is what users expect. + +## Acceptance Criteria + +### Response Size Display +- [x] `ResponseData` has `body_size_bytes: usize` populated from HTTP response +- [x] Tab bar shows size after duration: `"200 OK (245ms) · 1.2 KB"` +- [x] Size formatted correctly: `0 B`, `512 B`, `1.0 KB`, `2.5 MB`, `1.1 GB` +- [x] Size hidden when terminal inner width < 50 columns +- [x] No size shown for error/loading/empty/cancelled states + +### One-Key Copy +- [x] `c` in Navigation mode (response focused) copies current tab content +- [x] Toast shows `"Copied response body (1.2 KB)"` or `"Copied response headers"` +- [x] `"No response to copy"` toast when no successful response exists +- [x] Copied text is the formatted (pretty-printed) body or rendered headers + +### Save to File +- [x] `S` in Navigation mode (response focused) opens save popup +- [x] Center-screen popup with `TextInput` for path entry +- [x] Enter writes file, Esc cancels +- [x] Tilde expansion works (`~/output.json` resolves correctly) +- [x] Error toast on invalid path / permission error +- [x] Success toast with path and size +- [x] Save popup intercepts all keys (no bleed-through to vim/navigation) + +### Response Body Search +- [x] `/` in Editing Normal mode on Body tab opens search bar +- [x] Search bar renders at bottom of response content area (1 row) +- [x] Typing incrementally highlights matches in the response body +- [x] Match count displayed as `current/total` in search bar +- [x] Enter confirms search, closes input bar, keeps highlights +- [x] Esc cancels search, clears query and highlights +- [x] `n` moves to next match (wraps around) +- [x] `N` moves to previous match (wraps around) +- [x] `Ctrl+I` toggles case sensitivity with visual indicator +- [x] Current match highlighted differently (LightRed) from other matches (Yellow) +- [x] Search highlights overlay JSON syntax colors correctly +- [x] Auto-scroll to current match position +- [x] Search state cleared when new response arrives +- [x] Search only active on Body tab;
