Event listener options

vue/v-on-event-hyphenation

The original "always" and "never" strings remain valid. The object form defaults to { style: "always", ignore: [], autofix: false }. Each ignore entry is a case-sensitive literal substring, so "update:" exempts @update:modelValue, while "Update:" and "update:*" do not. Entries must be unique, must contain a non-whitespace character, and must not end in :exit. The whole rule policy is replaced by a later matching configuration; {} clears inherited exemptions and resets autofix to false. Options do not enable a disabled rule. ignoreTags is not exposed.

Set autofix: true to offer static event-argument edits, then use the CLI's --fix or the host's fix command to apply them. The edit keeps @/v-on:, modifiers, and handler expressions. Names containing _ keep their diagnostic without a fix. In never mode the converter removes a hyphen before an ASCII word character; a hyphen before a non-ASCII letter can remain and still be reported. An unchanged edit leaves file bytes untouched.

import { defineConfig } from "@vizejs/vite-plugin/vite-plus";

export default defineConfig({}).withVue({
  linter: {
    rules: { "vue/v-on-event-hyphenation": "warn" },
    ruleOptions: {
      "vue/v-on-event-hyphenation": { style: "always", ignore: ["update:"], autofix: true },
    },
  },
});

The Vue rule options describe the checked listener forms.
