The filesystem acts as the index — no registry file is needed. + +## Substitution + +### How It Works + +When you press `Ctrl+R` to send a request, Perseus: + +1. Reads the raw text from the URL, headers, body, and auth fields +2. Looks up the active environment's enabled variables +3. Scans each field for `{{variable_name}}` patterns +4. Replaces matched patterns with variable values +5. Sends the resolved request + +The editor always displays the raw template text. Substitution only affects the outgoing HTTP request. + +### Substitution Scope + +Variables are substituted in all user-editable request fields: + +| Field | Example Template | Resolved Value | +|-------|-----------------|----------------| +| URL | `{{base_url}}/api/users` | `http://localhost:3000/api/users` | +| Headers | `X-Api-Key: {{api_key}}` | `X-Api-Key: sk-abc123` | +| Body | `{"token": "{{auth_token}}"}` | `{"token": "my-secret-token"}` | +| Bearer Token | `{{api_token}}` | `dev-token-abc123` | +| Basic Username | `{{username}}` | `admin` | +| Basic Password | `{{password}}` | `secret` | +| API Key Name | `{{key_header}}` | `X-Custom-Auth` | +| API Key Value | `{{key_value}}` | `key-12345` | + +Method and response fields are **not** substituted. + +### Unresolved Variables + +If a `{{variable}}` has no matching key in the active environment (or no environment is selected), it is left as literal text in the sent request. This matches Postman behavior and is non-blocking — the request still sends. + +For example, with only `base_url` defined: + +``` +Template: {{base_url}}/api/{{version}}/users +Sent as: http://localhost:3000/api/{{version}}/users +``` + +This makes it easy to spot missing variables in the response or URL bar. + +### Disabled Variables + +Variables with `"enabled": false` are excluded from substitution. Use this to temporarily disable a variable without deleting it from the file: + +```json +{ + "key": "debug_token", + "value": "super-secret", + "enabled": false, + "type": "default" +} +``` + +`{{debug_token}}` will remain as literal text in sent requests until you set `enabled` back to `true`. + +### Edge Cases + +| Input | Result | Reason | +|-------|--------|--------| +| `{{}}` | `{{}}` | Empty variable name — left as literal | +| `{{name` | `{{name` | Unclosed braces — left as literal | +| `{{a}}{{b}}` | Both resolved | Adjacent variables are handled correctly | +| `{{a}}` with no env | `{{a}}` | No environment selected — left as literal | +| `{{a}}` where `a` resolves to `{{b}}` | Value of `a` (no re-scan) | Single-pass substitution; no nested resolution | + +## Environment Switching + +### Quick-Switch Popup + +Press `Ctrl+N` from any mode (Navigation, Editing, or Sidebar) to open the environment switcher popup. + +``` +┌─ Environment ──────────────┐ +│ ✓ No Environment │ +│ dev │ +│ production │ +│ staging │ +└────────────────────────────┘ +``` + +- A checkmark (`✓`) marks the currently active environment +- The highlighted item is shown with inverted colors +- "No Environment" disables all variable substitution + +### Popup Controls + +| Key | Action | +|-----|--------| +| `j` / `Down` | Move selection down | +| `k` / `Up` | Move selection up | +| `Enter` | Activate the selected environment | +| `Esc` / `q` | Close without changing | + +The popup closes automatically when you press `Enter` or `Esc`.

Switch between environments with `Ctrl+N` — each request hits the right server with the right credentials. + +### Auth Token Rotation + +Store auth tokens in environment variables to update them in one place: + +```json +{ + "name": "dev", + "values": [ + { "key": "base_url", "value": "http://localhost:3000", "enabled": true, "type": "default" }, + { "key": "access_token", "value": "eyJhbGciOiJIUzI1NiIs...", "enabled": true, "type": "default" } + ] +} +``` + +In the Auth tab, select Bearer Token and set the token field to `{{access_token}}`. When the token expires, update the value in `dev.json` and restart Perseus — all requests using `{{access_token}}` pick up the new value. + +### Shared Team Environments + +Environment files are plain JSON in the `.perseus/` directory and can be committed to version control: + +``` +# .gitignore +.perseus/environments/local.json # Personal env — don't commit +``` + +``` +# Committed to git +.perseus/environments/dev.json # Team dev environment +.perseus/environments/staging.json # Shared staging config +``` + +Team members get the shared environments automatically when they pull the repository.

This means: + +- Postman environment exports can be placed directly in `.perseus/environments/` and used by Perseus +- Perseus environment files can be imported into Postman as environments +- The `key`, `value`, `enabled`, and `type` fields are preserved in both directions + +To use a Postman environment export: + +1. Export the environment from Postman (Settings > Environments > Export) +2. Copy the exported `.json` file into `.perseus/environments/` +3.

Individual files are more git-friendly. +2. **OpenAPI import depth**: Should we parse full request body schemas and generate example bodies, or just extract endpoint paths and methods? +3. **WebSocket UI**: Should WebSocket be a separate mode/panel or integrated into the existing request/response layout? +4. **Multi-tab limit**: Should there be a max number of open tabs, or let memory be the limit? +5. **GraphQL schema caching**: Cache introspected schemas to disk, or fetch fresh each time? +6. **Config file precedence**: If a project `.perseus/config.toml` conflicts with global `~/.config/perseus/config.toml`, which wins? (Proposed: project overrides global) +7. **History scope**: Should history be global or per-project? +8. **Hotkey allocation**: Several new features need keybindings (environment switch, curl import, code gen, history). Ctrl+E is already used for sidebar toggle. Need a comprehensive keybinding audit before Phase 1 planning to avoid conflicts. +9. **Request panel tab overflow**: With Params, Auth, Headers, Body, and Docs tabs, the request panel may overflow in narrow terminals. Consider a scrollable tab bar or abbreviated labels. +10. **Multi-tab timing**: Should multi-tab be built before or after environment variables? Environments apply per-tab, so the interaction model matters. + +--- + +## Phase Priority Summary + +| Phase | Focus | Impact | Complexity | +|-------|-------|--------|------------| +| Phase 1 | Config, Auth, Environments, Body Types, Methods, Query Params, Response Search/Metadata | **Critical** — unblocks standard API workflows | Medium-High | +| Phase 2 | Curl/Postman/OpenAPI Import, Curl Export, Code Gen, History, Request Notes | **High** — enables adoption and sharing | Medium | +| Phase 3 | Proxy, SSL, Cookies, Redirect/Timeout Control | **Medium** — needed for enterprise/advanced use | Low-Medium | +| Phase 4 | Multi-Tab, GraphQL, WebSocket | **Medium** — major extensions beyond standard HTTP | **High** — architectural changes | + +--- + +## Implementation Strategy + +**One plan per feature.** Each feature gets its own plan file in `docs/plans/` with: +- Multiple implementation phases (small, verifiable steps) +- Each phase verified (compiles, tests pass, manual check) and committed before moving to the next +- Plan file naming: `docs/plans/YYYY-MM-DD-.md` + +This keeps PRs focused, makes rollbacks clean, and allows features to be developed independently or in parallel. + +**Suggested implementation order** (within Phase 1): +1.

Isolates String allocation to custom methods only. Avoids massive refactor of every `method` usage site. | +| Storage serialization for custom methods | `PostmanRequest.method` is already `String` — no change needed. Remove/simplify `storage::models::HttpMethod` since Postman format is the primary format. | Postman collections already store methods as plain strings. The typed storage enum adds complexity without value. | +| `from_str()` fix | Return `Method::Custom(original)` for unrecognized strings instead of defaulting to GET | Fixes the data loss bug. Any valid HTTP method token is preserved through save/load roundtrips. | +| Body gating for custom methods | Allow body for POST, PUT, PATCH, DELETE, and any custom method. Drop body for GET, HEAD, OPTIONS. | WebDAV methods (PROPFIND, REPORT) require bodies. Users choosing custom methods should get full control. DELETE included since some APIs use DELETE with body. | +| Custom method validation | Auto-uppercase input. Reject empty strings and non-ASCII characters. Max 20 characters. | HTTP methods are case-sensitive per RFC 7230 but convention is uppercase. Length limit prevents layout overflow. | +| Method colors | HEAD=Cyan, OPTIONS=White, Custom=DarkGray | Cyan and White are unused in the current palette. DarkGray signals "non-standard" for custom methods. | +| Method area width | Keep `Constraint::Length(10)` — truncate with ellipsis for methods > 8 chars | OPTIONS (7 chars) fits. Custom methods that overflow get visual truncation. Avoids layout disruption. | +| Custom method popup UX | "Custom..." entry at bottom of popup list → inline text input on selection | Consistent with the existing popup interaction model.

Full vim mode on all fields. Users expect the same editing experience everywhere. | +| Auth type selector | Popup (like method selector) | Proven interaction pattern. j/k + Enter. Familiar to users. | +| API Key location selector | Toggle with Enter (cycles Header ↔ Query Param) | Only 2 options — a popup is overkill. | +| Tab order | Headers → Auth → Body | Auth logically sits between "what headers to send" and "what body to send". | +| Tab cycling | Circular (Body → Headers wraps around) | Matches existing 2-tab toggle behavior extended to 3. | +| Auth vs manual header conflict | No conflict detection; both sent | Matches Postman behavior. User is responsible. Keeps MVP simple. | +| Auth data on type switch | Clear previous type's data | Matches Postman behavior. Simpler state model. Avoids lossy Postman roundtrip (v2.1 only stores active type). | +| Password masking | No masking | Developer tool in a terminal — same context as `curl -u user:pass`. Masking conflicts with vim visual mode and cursor positioning. | +| RequestField for auth | Single `RequestField::Auth` + separate `AuthField` sub-enum on `FocusState` | Minimizes changes to focus navigation. `AuthField` is cursor focus state (not request data), so it lives on `FocusState` alongside `panel` and `request_field`. | +| Auth injection layer | Extend `http::send_request()` signature with an `AuthConfig` enum param | Clean separation. Uses reqwest's built-in `.bearer_auth()` / `.basic_auth()` for correctness. Keeps auth data out of the visible headers text. | +| Unsupported Postman auth types | Ignore gracefully (default to NoAuth) | Postman import doesn't exist yet. When it ships, extend the auth structs to handle additional types. | +| Auth type in tab label | Show "Auth (Bearer)" / "Auth (Basic)" / etc. | At-a-glance visibility of configured auth without switching tabs. | +| Base64 encoding | Use reqwest's `.basic_auth()` | No need for a separate `base64` crate. reqwest handles encoding correctly per RFC 7617. | + +--- + +## Implementation Phases + +### Phase A: Postman-Compatible Auth Data Model + +Add the serialization structs for auth in the Postman Collection v2.1 format. + +**A.1: Add auth structs to `src/storage/postman.rs`** + +- [x] Add `PostmanAuthAttribute` struct: + ```rust + #[derive(Debug, Clone, Serialize, Deserialize)] + pub struct PostmanAuthAttribute { + pub key: String, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub value: Option, + #[serde(rename = "type", default, skip_serializing_if = "Option::is_none")] + pub attr_type: Option, + } + ``` + +- [x] Add `PostmanAuth` struct: + ```rust + #[derive(Debug, Clone, Serialize, Deserialize)] + pub struct PostmanAuth { + #[serde(rename = "type")] + pub auth_type: String, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub bearer: Option>, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub basic: Option>, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub apikey: Option>, + } + ``` + +- [x] Add `auth` field to `PostmanRequest` (`src/storage/postman.rs:32-41`): + ```rust + #[serde(default, skip_serializing_if = "Option::is_none")] + pub auth: Option, + ``` + +- [x] Update `PostmanRequest::new()` to set `auth: None` + +**A.2: Add helper methods on `PostmanAuth`** + +- [x] `PostmanAuth::bearer(token: &str) -> PostmanAuth` — constructs a bearer auth object +- [x] `PostmanAuth::basic(username: &str, password: &str) -> PostmanAuth` — constructs a basic auth object +- [x] `PostmanAuth::apikey(key: &str, value: &str, location: &str) -> PostmanAuth` — constructs an apikey auth object +- [x] `PostmanAuth::get_bearer_token(&self) -> Option<&str>` — extracts token from bearer array +- [x] `PostmanAuth::get_basic_credentials(&self) -> Option<(&str, &str)>` — extracts username/password +- [x] `PostmanAuth::get_apikey(&self) -> Option<(&str, &str, &str)>` — extracts key, value, location + +**A.3: Verify backward compatibility** + +- [x] Compile — no other code changes needed (auth is `Option` with `serde(default)`) +- [x] Verify: existing collection JSON without `auth` field deserializes correctly (auth = None) +- [x] Verify: a JSON with an `auth` object round-trips correctly through serialize/deserialize + +**Commit**: `feat(storage): add Postman v2.1 auth data model` + +--- + +### Phase B: In-Memory Auth State on RequestState + +Add the runtime auth state model with TextArea editors. + +**B.1: Define auth enums in `src/app.rs`** + +- [x] Add `AuthType` enum: + ```rust + #[derive(Debug, Clone, Copy, PartialEq, Eq, Default)] + pub enum AuthType { + #[default] + NoAuth, + Bearer, + Basic, + ApiKey, + } + ``` + +- [x] Add `ApiKeyLocation` enum: + ```rust + #[derive(Debug, Clone, Copy, PartialEq, Eq, Default)] + pub enum ApiKeyLocation { + #[default] + Header, + QueryParam, + } + ``` + +- [x] Add `AuthField` enum (tracks focused sub-field within Auth tab): + ```rust + #[derive(Debug, Clone, Copy, PartialEq, Eq, Default)] + pub enum AuthField { + #[default] + AuthType, // The type selector row + // Bearer fields + Token, + // Basic fields + Username, + Password, + // API Key fields + KeyName, + KeyValue, + KeyLocation, // Header/QueryParam toggle + } + ``` + +- [x] Add constants on `AuthType`: + - `AuthType::ALL: [AuthType;

The system supports two tiers — global config at `$XDG_CONFIG_HOME/perseus/config.toml` and project-level overrides at `.perseus/config.toml` — with field-level merging. This is the foundational infrastructure that multiple Phase 1+ features (proxy, SSL, redirects, history, auth) depend on. + +## Problem Statement + +Perseus currently hardcodes all configuration values: + +| Setting | Location | Current Value | +|---------|----------|---------------| +| HTTP timeout | `app.rs:496` | `Duration::from_secs(30)` | +| Sidebar width default | `app.rs:521` | `32` | +| Sidebar width range | `app.rs:2661-2663` | `28..=42` | +| Follow redirects | Not configured | reqwest default (10 max) | +| SSL verification | Not configured | reqwest default (enabled) | +| Proxy | Not configured | reqwest default (system) | + +Users cannot customize HTTP behavior (timeouts, redirects, proxy, SSL), UI defaults (sidebar width, tab size), or prepare for upcoming features (history limits). Corporate environments that require proxy or custom CA certificates cannot use Perseus without code changes. + +## Proposed Solution + +A new `src/config.rs` module that: +1.

URL always contains enabled params. Matches Postman behavior. | +| Disabled params storage | `query_params: Vec` on `RequestState` + Postman `url.query` array | Disabled params cannot exist in the URL string, so they live in the KV table and the Postman `query` array. | +| KV-to-URL sync trigger | Immediate on every KV mutation | Cell edit confirm, row add/delete, toggle all immediately update the URL string. User sees the URL change in real-time. | +| URL-to-KV sync trigger | On leaving URL editing mode (Esc) | Parsing mid-keystroke would be disruptive. Sync fires when user finishes URL editing. | +| Tab position | First: Params \| Headers \| Auth \| Body | Params relates directly to the URL input above. First position creates spatial consistency. | +| KV table pattern | Reuse `KvPair`, `KvFocus`, `KvColumn` from body types | Same component pattern. Separate `params_kv_focus` in `FocusState` avoids state pollution with body KV editors. | +| URL encoding | KV table shows decoded values | Users type `hello world`, URL shows `hello%20world`. Decoding happens on URL-to-KV parse; encoding on KV-to-URL rebuild. | +| Fragment preservation | Fragment is preserved during sync | `https://host/path?q=test#section` — the `#section` fragment is kept intact when rebuilding the query string. | +| Param reordering | Deferred | Not supported in initial implementation. Can be added later with Shift+J/K keybindings. | +| Auth API Key visibility | Not shown in Params tab | Consistent with auth headers being invisible in the Headers tab. Injected at send time only. | +| URL parser | Standalone `src/url.rs` module | Avoids adding the `url` crate dependency. Query param parsing is simple string splitting. | + +### Key Files and Touchpoints + +| File | What Changes | +|------|-------------| +| `src/url.rs` | **New file** — URL parsing utilities (extract base, parse query, rebuild URL) | +| `src/app.rs:67-73` | Add `RequestTab::Params` variant and update `request_tab_from_str`, `request_tab_to_str` | +| `src/app.rs:411-419` | Add `RequestField::Params` variant | +| `src/app.rs:421-428` | Add `params_kv_focus: KvFocus` to `FocusState` | +| `src/app.rs:534-550` | Add `query_params: Vec` to `RequestState` | +| `src/app.rs:607-629` | Update `set_contents()` to reset query params | +| `src/app.rs:700-715` | Update `active_editor()` for Params KV cell editing | +| `src/app.rs:3281-3291` | Update `is_editable_field()` for Params | +| `src/app.rs:3293-3336` | Update `next_horizontal()`, `prev_horizontal()` for Params | +| `src/app.rs:3338-3385` | Update `next_vertical()`, `prev_vertical()` for Params | +| `src/app.rs:3387-3403` | Update `next_request_tab()`, `prev_request_tab()` for 4-tab cycling | +| `src/app.rs:3405-3416` | Update `sync_field_to_tab()` for Params | +| `src/app.rs:1432-1464` | Update `build_postman_request()` to emit structured URL with query array | +| `src/app.rs:1466-1489` | Update `open_request()` to read query array from Postman URL | +| `src/app.rs:3208-3240` | Update `send_request()` if needed (URL already has params, so minimal change) | +| `src/app.rs:2162-2188` | Update `prepare_editors()` for params KV cell editing | +| `src/ui/mod.rs:576-614` | Update `render_request_panel()` to render Params tab content | +| `src/ui/mod.rs:616-679` | Update `render_request_tab_bar()` to include Params tab | +| `src/storage/postman.rs:54-64` | Add `PostmanQueryParam` struct, update `PostmanRequest::new()` for structured URL | +| `src/main.rs` | Add `mod url;` declaration | + +--- + +## Implementation Phases + +### Phase A: URL Parsing Utility + Query Param Data Model + +Build the URL parsing module and extend `RequestState` with query param state. + +**A.1: Create `src/url.rs` — URL parsing utility module** + +- [ ] Create `src/url.rs` with the following functions: + + ```rust + /// Split a URL into (base, query_string, fragment). + /// base: everything before '?' + /// query_string: between '?' and '#' (without the '?') + /// fragment: after '#' (without the '#') + /// + /// Examples: + /// "https://api.com/search?q=test#top" + /// → ("https://api.com/search", Some("q=test"), Some("top")) + /// "https://api.com/search" + /// → ("https://api.com/search", None, None) + /// "https://api.com/search?" + /// → ("https://api.com/search", Some(""), None) + pub fn split_url(url: &str) -> (&str, Option<&str>, Option<&str>) + ``` + + ```rust + /// Parse a query string into key-value pairs. + /// Splits on '&', then each pair on the first '='. + /// URL-decodes both key and value. + /// + /// Examples: + /// "q=test&page=1" → [("q", "test"), ("page", "1")] + /// "data=a%3Db%3Dc" → [("data", "a=b=c")] (decoded) + /// "key=" → [("key", "")] + /// "key" → [("key", "")] (no value, treat as empty) + /// "" → [] + /// "&&&" → [] (skip empty segments) + pub fn parse_query_string(query: &str) -> Vec<(String, String)> + ``` + + ```rust + /// Rebuild a full URL from base + enabled params + optional fragment. + /// URL-encodes keys and values. + /// + /// Example: + /// build_url("https://api.com/search", + /// &[("q", "hello world"), ("page", "1")], + /// Some("top")) + /// → "https://api.com/search?q=hello%20world&page=1#top" + pub fn build_url(base: &str, params: &[(&str, &str)], fragment: Option<&str>) -> String + ``` + + ```rust + /// URL-encode a string (percent-encoding for query param components). + /// Encodes everything except unreserved characters (A-Z, a-z, 0-9, '-', '_', '.', '~'). + /// Spaces encoded as %20 (not +, to match URL standard). + /// Preserves {{variable}} template markers without encoding. + pub fn percent_encode(input: &str) -> String + ``` + + ```rust + /// URL-decode a percent-encoded string. + /// Decodes %XX sequences back to characters. + /// Decodes '+' as space (for compatibility with form-encoded strings). + /// Preserves {{variable}} template markers without decoding. + pub fn percent_decode(input: &str) -> String + ``` + +- [ ] Handle edge cases: + -

Also breaks copy-paste workflow where users paste a full URL and expect it to work. | +| Dual source with last-write-wins | Too complex. Race conditions between URL and KV edits. No clear mental model for users about which "wins". | +| Use `url` crate for parsing | Adds a dependency for simple string splitting. Perseus URLs may contain `{{var}}` template markers that the `url` crate would reject as invalid. Custom parser handles these gracefully. | +| Sync on every keystroke in URL editor | Disruptive — mid-typing, the KV table would flicker. `?q=t` → `?q=te` → `?q=tes` → `?q=test` would cause 4 KV table updates. Sync on Esc is cleaner. | +| Separate `ParamsField` enum for sub-navigation (like `BodyField`) | Unnecessary — params are always a KV table, unlike Body which has mode selector + content area. `KvFocus` (row + column) is sufficient. | +| Show API Key query param in Params tab | Breaks the separation between auth and params.

No data loss on Raw ↔ JSON ↔ XML. | +| Separate state for KV modes | `Vec` for urlencoded, `Vec` for multipart | Structured data can't share a TextArea. Separate vectors allow independent state. | +| Content-Type injection | At send time, not stored in visible headers | Matches Postman behavior. Avoids conflict with user-set headers. Auto-injected header is invisible in the Headers tab. | +| Content-Type override behavior | Auto-set only if user hasn't manually set Content-Type in headers | Respect user's explicit header. Check headers text for existing Content-Type before injecting. | +| Key-value cell editing | Temporary TextArea for active cell | Avoids N*2 persistent TextAreas. Create TextArea on Enter, extract text on Esc. | +| KV pair enable/disable | `enabled: bool` per pair, toggle with Space | Matches Postman behavior. Users can disable params without deleting. | +| Body mode label in tab bar | "Body (JSON)" / "Body (Form)" / etc. | At-a-glance visibility of body mode. Matches auth tab pattern "Auth (Bearer)". | +| JSON validation | Visual indicator only (checkmark/X in mode selector row) | Don't block sending — user may intentionally send malformed JSON to test error handling. | +| JSON pretty-format | Not auto-applied on paste for MVP | Too magical. Can be added later as a keyboard shortcut. Content preservation is more important. | +| Multipart file type | Per-row type toggle (Text/File) | Matches Postman's multipart model where each field can be text or file. | +| Binary file validation | At send time only | File may not exist yet during editing. Show error in response area if file not found at send. | +| Body mode on type switch | Preserve all mode data in memory | Switching modes doesn't clear data. User can switch back without losing work. Only the active mode's data is sent. | +| Body popup trigger | Enter/i on body mode selector row (like auth type) | Consistent interaction pattern across method, auth type, and body mode selectors. | + +--- + +## Implementation Phases + +### Phase A: Postman-Compatible Body Data Model + +Extend the storage structs to support all Postman v2.1 body modes. + +**A.1: Add body-related structs to `src/storage/postman.rs`** + +- [ ] Add `PostmanBodyOptions` struct (raw language hint): + ```rust + #[derive(Debug, Clone, Serialize, Deserialize)] + pub struct PostmanBodyOptions { + #[serde(default, skip_serializing_if = "Option::is_none")] + pub raw: Option, + } + + #[derive(Debug, Clone, Serialize, Deserialize)] + pub struct PostmanRawLanguage { + pub language: String, // "json", "xml", "text" + } + ``` + +- [ ] Add `PostmanKvPair` struct (for urlencoded): + ```rust + #[derive(Debug, Clone, Serialize, Deserialize)] + pub struct PostmanKvPair { + pub key: String, + pub value: String, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub disabled: Option, + } + ``` + +- [ ] Add `PostmanFormParam` struct (for multipart formdata): + ```rust + #[derive(Debug, Clone, Serialize, Deserialize)] + pub struct PostmanFormParam { + pub key: String, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub value: Option, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub src: Option, // file path for type="file" + #[serde(rename = "type", default = "default_form_type")] + pub param_type: String, // "text" or "file" + #[serde(default, skip_serializing_if = "Option::is_none")] + pub disabled: Option, + } + + fn default_form_type() -> String { + "text".to_string() + } + ``` + +- [ ] Add `PostmanFileRef` struct (for binary): + ```rust + #[derive(Debug, Clone, Serialize, Deserialize)] + pub struct PostmanFileRef { + #[serde(default, skip_serializing_if = "Option::is_none")] + pub src: Option, + } + ``` + +**A.2: Extend `PostmanBody` struct (`src/storage/postman.rs:74-79`)** + +- [ ] Add new fields to `PostmanBody`: + ```rust + #[derive(Debug, Clone, Serialize, Deserialize)] + pub struct PostmanBody { + pub mode: String, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub raw: Option, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub options: Option, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub urlencoded: Option>, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub formdata: Option>, + #[serde(default, skip_serializing_if = "Option::is_none")] + pub file: Option, + } + ``` + +**A.3: Update `PostmanRequest::new()` (`src/storage/postman.rs:121-142`)** + +- [ ] Update the body construction to include `options: None`, `urlencoded: None`, `formdata: None`, `file: None` +- [ ] Keep existing raw body creation logic unchanged + +**A.4: Add helper constructors on `PostmanBody`** + +- [ ] `PostmanBody::raw(text: &str) -> PostmanBody` — mode "raw", no language +- [ ] `PostmanBody::json(text: &str) -> PostmanBody` — mode "raw" with options.raw.language = "json" +- [ ] `PostmanBody::xml(text: &str) -> PostmanBody` — mode "raw" with options.raw.language = "xml" +- [ ] `PostmanBody::urlencoded(pairs: Vec) -> PostmanBody` — mode "urlencoded" +- [ ] `PostmanBody::formdata(params: Vec) -> PostmanBody` — mode "formdata" +- [ ] `PostmanBody::file(path: &str) -> PostmanBody` — mode "file" + +**A.5: Verify backward compatibility** + +- [ ] Compile — no other code changes needed (new fields are `Option` with `serde(default)`) +- [ ] Existing collection JSON without new body fields deserializes correctly +- [ ] JSON with extended body fields round-trips correctly + +**Commit**: `feat(storage): extend Postman body model for all body types` + +--- + +### Phase B: BodyMode Enum + In-Memory State + +Add the runtime body mode state model to `RequestState`. + +**B.1: Define body mode enum in `src/app.rs`** + +- [ ] Add `BodyMode` enum: + ```rust + #[derive(Debug, Clone, Copy, PartialEq, Eq, Default)] + pub enum BodyMode { + #[default] + Raw, + Json, + Xml, + FormUrlEncoded, + Multipart, + Binary, + } + ``` + +- [ ] Add constants on `BodyMode`: + - `BodyMode::ALL: [BodyMode;

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.
