Rohit Nair P 4879f9da99 fix: improve duplicate module import error message (#18016) ... ## Description **While investigating the compiler analysis phase for errors or missing lines, I located an explicit `TODO fix the message here` comment in the source code (`packages/svelte/src/compiler/phases/2-analyze/visitors/shared/utils.js`).** ### Triggering Code ```svelte <script module> import { foo } from './somewhere.js'; </script> <script> let foo = 'conflict'; // Triggers the duplicate module import error </script> ``` ## The Bug When a component author creates a local `let` declaration in the instance `<script>` block that shadows a variable imported in the `<script module>` block, the compiler emits a `declaration_duplicate_module_import` error. However, the error message text was misleading. It stated: ```diff - Cannot declare a variable with the same name as an import inside `<script module>` + Cannot declare a variable with the same name as an import from `<script module>` ``` This incorrectly implies that the duplicate declaration itself is happening *inside* the module script block, rather than colliding with an import *from* that block. ## Changes Made | Action | Target (File / Function) | Description | | :--- | :--- | :--- | | **Template Fix** | `packages/svelte/messages/compile-errors/script.md` | Changed "inside" to "from" to accurately reflect the nature of the shadow collision. | | **Regenerated Errors** | `packages/svelte/src/compiler/errors.js` | Ran `pnpm generate` to apply the updated markdown template into the dictionary list. | | **Removed TODO** | `ensure_no_module_import_conflict` function | Removed the original `// TODO fix the message here` notation from the validator. | | **Test Adjustments** | `illegal-variable-declaration/errors.json` | Updated the validator test suite snapshots to assert against the correct error message format. | ## Validation Results * The error correctly throws when a user replicates this component structure. * Vitest suite `tests/validator/test.ts` successfully asserts the new, clearer message. --- ### Before submitting the PR, please make sure you do the following - [x] It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs - [x] Prefix your PR title with `feat:`, `fix:`, `chore:`, or `docs:`. - [x] This message body should clearly illustrate what problems it solves. - [x] Ideally, include a test that fails without this PR but passes with it. - [x] If this PR changes code within `packages/svelte/src`, add a changeset (`npx changeset`). ### Tests and linting - [x] Run the tests with `pnpm test` and lint the project with `pnpm lint` # THANK YOU		7 months ago
