+# Submit Formatting Button State Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Show `格式化中` on the submit button during automatic formatting, then show `正在提交` continuously while the submission request is pending.
+
+**Architecture:** Extract the button presentation rules into a small pure TypeScript function so the state priority can be tested without adding a frontend test framework. Keep formatter and submission-request flags local to `SubmitCode.vue`, with `finally` blocks ensuring both flags clear on every outcome.
+
+**Tech Stack:** Vue 3 Composition API, TypeScript, Node.js built-in test runner, Rsbuild
+
+---
+
+### Task 1: Define and test submit button presentation rules
+
+**Files:**
+- Create: `tests/submitButtonState.test.ts`
+- Create: `src/oj/problem/components/submitButtonState.ts`
+
+- [ ] **Step 1: Write the failing test**
+
+Create `tests/submitButtonState.test.ts`:
+
+```ts
+import assert from "node:assert/strict"
+import test from "node:test"
+import { getSubmitButtonState } from "../src/oj/problem/components/submitButtonState.ts"
+
+const idleInput = {
+  isAuthed: true,
+  hasCode: true,
+  isFormatting: false,
+  isSubmitting: false,
+  isJudging: false,
+  isCooldown: false,
+}
+
+test("shows a disabled loading state while formatting", () => {
+  assert.deepEqual(
+    getSubmitButtonState({ ...idleInput, isFormatting: true }),
+    {
+      disabled: true,
+      label: "格式化中",
+      icon: "eos-icons:loading",
+    },
+  )
+})
+
+test("shows submitting immediately after formatting", () => {
+  assert.deepEqual(
+    getSubmitButtonState({ ...idleInput, isSubmitting: true }),
+    {
+      disabled: true,
+      label: "正在提交",
+      icon: "eos-icons:loading",
+    },
+  )
+})
+
+test("preserves existing login, judging, cooldown, and idle states", () => {
+  assert.deepEqual(
+    getSubmitButtonState({ ...idleInput, isAuthed: false }),
+    {
+      disabled: true,
+      label: "请先登录",
+      icon: "ph:play-fill",
+    },
+  )
+  assert.deepEqual(getSubmitButtonState({ ...idleInput, isJudging: true }), {
+    disabled: true,
+    label: "正在评分",
+    icon: "eos-icons:loading",
+  })
+  assert.deepEqual(getSubmitButtonState({ ...idleInput, isCooldown: true }), {
+    disabled: true,
+    label: "正在冷却",
+    icon: "ph:lightbulb-fill",
+  })
+  assert.deepEqual(getSubmitButtonState(idleInput), {
+    disabled: false,
+    label: "提交代码",
+    icon: "ph:play-fill",
+  })
+})
+```
+
+- [ ] **Step 2: Run the test to verify it fails**
+
+Run:
+
+```bash
+node --test tests/submitButtonState.test.ts
+```
+
+Expected: FAIL with `ERR_MODULE_NOT_FOUND` for `submitButtonState.ts`.
+
+- [ ] **Step 3: Implement the pure state function**
+
+Create `src/oj/problem/components/submitButtonState.ts`:
+
+```ts
+export interface SubmitButtonStateInput {
+  isAuthed: boolean
+  hasCode: boolean
+  isFormatting: boolean
+  isSubmitting: boolean
+  isJudging: boolean
+  isCooldown: boolean
+}
+
+export interface SubmitButtonState {
+  disabled: boolean
+  label: string
+  icon: string
+}
+
+export function getSubmitButtonState({
+  isAuthed,
+  hasCode,
+  isFormatting,
+  isSubmitting,
+  isJudging,
+  isCooldown,
+}: SubmitButtonStateInput): SubmitButtonState {
+  const disabled =
+    !isAuthed ||
+    !hasCode ||
+    isFormatting ||
+    isSubmitting ||
+    isJudging ||
+    isCooldown
+
+  let label = "提交代码"
+  if (!isAuthed) {
+    label = "请先登录"
+  } else if (isFormatting) {
+    label = "格式化中"
+  } else if (isSubmitting) {
+    label = "正在提交"
+  } else if (isJudging) {
+    label = "正在评分"
+  } else if (isCooldown) {
+    label = "正在冷却"
+  }
+
+  const icon =
+    isFormatting || isSubmitting || isJudging
+      ? "eos-icons:loading"
+      : isCooldown
+        ? "ph:lightbulb-fill"
+        : "ph:play-fill"
+
+  return { disabled, label, icon }
+}
+```
+
+- [ ] **Step 4: Run the test to verify it passes**
+
+Run:
+
+```bash
+node --test tests/submitButtonState.test.ts
+```
+
+Expected: 3 tests pass.
+
+### Task 2: Connect formatting and submission request lifecycle to the button
+
+**Files:**
+- Modify: `src/oj/problem/components/SubmitCode.vue`
+
+- [ ] **Step 1: Add local request states and computed presentation**
+
+Import `getSubmitButtonState`, add `isFormatting` and `isSubmittingRequest` refs, and replace the three existing button computed properties with:
+
+```ts
+const buttonState = computed(() =>
+  getSubmitButtonState({
+    isAuthed: userStore.isAuthed,
+    hasCode: codeStore.code.value.trim() !== "",
+    isFormatting: isFormatting.value,
+    isSubmitting: isSubmittingRequest.value || submitting.value,
+    isJudging: judging.value || pending.value,
+    isCooldown: isCooldown.value,
+  }),
+)
+```
+
+Use `buttonState.disabled`, `buttonState.icon`, and `buttonState.label` in the template.
+
+- [ ] **Step 2: Guard and track the formatting request**
+
+At the start of `submit`, return when `buttonState.value.disabled` is true. Around `formatCode`, set `isFormatting.value = true` before the request and clear it in `finally`:
+
+```ts
+isFormatting.value = true
+try {
+  const res = await formatCode({
+    code: codeStore.code.value,
+    language: formatLang,
+  })
+  codeStore.setCode(res.data.code)
+} catch (e: any) {
+  if (e?.error === "format-error") {
+    message.warning(`代码格式化失败：${e.data}，请检查代码后重试`)
+    return
+  }
+} finally {
+  isFormatting.value = false
+}
+```
+
+- [ ] **Step 3: Track the submission API request**
+
+Set `isSubmittingRequest.value = true` immediately before `submitCode`, keep the existing success flow inside the `try`, and clear the request state in `finally`:
+
+```ts
+isSubmittingRequest.value = true
+try {
+  const res = await submitCode(data)
+  console.log(`[Submit] 代码已提交: ID=${res.data.submission_id}`)
+
+  startCooldown()
+  startMonitoring(res.data.submission_id)
+  showResult.value = true
+} finally {
+  isSubmittingRequest.value = false
+}
+```
+
+- [ ] **Step 4: Run focused tests**
+
+Run:
+
+```bash
+node --test tests/submitButtonState.test.ts
+```
+
+Expected: 3 tests pass.
+
+- [ ] **Step 5: Run the production build**
+
+Run:
+
+```bash
+npm run build
+```
+
+Expected: Rsbuild exits with status 0.
+
+- [ ] **Step 6: Check the final diff**
+
+Run:
+
+```bash
+git diff --check
+git diff -- src/oj/problem/components/SubmitCode.vue src/oj/problem/components/submitButtonState.ts tests/submitButtonState.test.ts
+```
+
+Expected: no whitespace errors; diff is limited to the button state feature and its test.

+# Submit Formatting Button State
+
+## Goal
+
+Make the code submission button reflect the automatic formatting request that runs before submission.
+
+## Behavior
+
+- For Python3, C, and C++, the button displays `格式化中` while the formatting API request is pending.
+- During formatting, the button uses the existing loading icon and is disabled to prevent duplicate submissions.
+- After formatting succeeds, the existing submission flow continues and the button can display `正在提交`.
+- A formatting error stops submission and clears the formatting state before showing the existing warning.
+- A formatter server or network failure keeps the existing fallback behavior: clear the formatting state and submit the original code.
+- Languages without automatic formatting skip this state and submit directly.
+- Existing button labels and judging/cooldown behavior remain unchanged.
+
+## Implementation
+
+Add a component-local `isFormatting` ref in `SubmitCode.vue`.
+
+- Include it in `submitDisabled`.
+- Give it priority in `submitLabel`, using `格式化中`.
+- Include it in the loading-icon condition.
+- Set it immediately before `formatCode`.
+- Clear it in a `finally` block so every formatter outcome restores the button state.
+
+The state remains local because it is transient UI state owned only by the submission button.
+
+## Verification
+
+The frontend currently has no automated test suite. Verify with:
+
+- TypeScript production build.
+- Manual inspection of the state transitions for successful formatting, formatting errors, formatter infrastructure failures, and languages that do not format.
