Migrate remaining markdown-it plugins from JavaScript to TypeScript #2832
Conversation
issue was caused by a mismatch between ESM default export and CJS transpilation during testing. When service classes were converted to export default class, the imported objects in PluginEnvironment became module wrappers rather than the classes themselves Hence, updated initServices to check for a .default property on imported service classes before instantiation

Pull request overview
This PR continues the packages/core TypeScript migration by converting the remaining markdown-it plugins (and block-embed services) from CommonJS/JS to TypeScript with ESM imports/exports, and updates the core markdown-it setup and unit tests accordingly. It also introduces a new .opencode/ workflow/skill/template set and expands ignore patterns for plugin JS files.
Changes:
- Migrated multiple markdown-it plugins (radio-button, footnotes, center-text, colour-text, block-embed + services) to TypeScript/ESM and updated exports.
- Updated
packages/core/src/lib/markdown-it/index.tsand related unit tests to import the new TS plugin entrypoints. - Added
.opencode/workflows/skills/templates and updated.gitignore/.eslintignoreto ignore plugin JS outputs.

- The exported plugin name
centertext_pluginis inconsistent with the other migrated plugins (e.g.,footnotePlugin,radioButtonPlugin,colourTextPlugin) and with typical TS naming in this codebase. Consider exporting a camelCase alias (e.g.,centerTextPlugin) and optionally re-exporting the old name for compatibility within the repo.

BlockEmbedOptions.filterUrl is typed as (url: string) => string, but VideoServiceBase.getFilteredVideoUrl calls it with 4 arguments (url, serviceName, videoID, options). This is a typing regression that prevents consumers from providing a correctly-typed filter function without casting. Consider exporting/reusing a UrlFilterDelegate type here (and updating filterUrl to that signature).

setup requires an options argument, but it is used via md.use(blockEmbedPlugin) without options. With strict TS settings, a plugin function should accept an optional options parameter to match markdown-it's plugin signature. Make options optional (and propagate that to PluginEnvironment's constructor) so both .use(plugin) and .use(plugin, opts) type-check and behave consistently.

postProcess currently clears the text content for any remaining # delimiter tokens, which changes rendering for invalid/incomplete colour syntax (previously these markers would render as literal text). The PR description says there are no functional changes; if that’s the intent, this cleanup should be removed or guarded so only matched marker tokens are altered. If the new behavior is intended, add/adjust tests to assert the exact output for invalid cases.

Leftover commented-out require(...) line should be removed to keep the test file clean (and avoid accumulating dead code during the TS migration).

The generated <input> HTML is missing a whitespace separator before type="radio" when disableRadio is false, producing name="..."type="radio". Add a leading space before type (or ensure disabledAttr always includes a leading space) so the markup is valid in both branches.

PR description focuses on migrating markdown-it plugins to TypeScript, but this PR also adds a substantial .opencode/ workflow/skill/template set and new GitHub Action-like YAML files. If these are intentional, please call them out in the PR description (or split them into a separate PR) to keep review scope clear.

There was a problem hiding this comment.
digest('hex').substring(2, 5) is not equivalent to the old substr(2, 5): substring(2, 5) returns only 3 characters (end index), which reduces group-id entropy and can change grouping/cause collisions. Use slice(2, 7) (or an equivalent 5-char extraction) to preserve the previous behavior without relying on deprecated substr.

Leftover commented-out require('./plugins/markdown-it-double-delimiter') can be removed now that the file has been migrated to ESM imports; keeping commented code around makes the TS migration harder to follow over time.

What is the purpose of this pull request?
This PR continues the TypeScript migration effort in the core package.
Closes #2745
Overview of changes:
This PR was generated using the
create-pull-requestskill, and then partially edited by me.Migrates the following JavaScript files in
packages/core/src/lib/markdown-it/plugins/to TypeScript:markdown-it-block-embed/(including all video service implementations)markdown-it-center-textmarkdown-it-colour-textmarkdown-it-double-delimitermarkdown-it-footnotesmarkdown-it-radio-buttonAll associated test files have been updated to import from the new TypeScript sources.
Anything you'd like to highlight/discuss:
The migration involved:
The changes are purely structural - no functional modifications were made to the plugin logic.
Notably, I added specific interfaces for each services within the markdown-it-block-embed/services, the aim of which will be to provide better control over how each plugin is configured just like before. i.e. it stays objects that are
undefinednaturally, which is exactly what the logic expects.Due to the conversion from JavaScript to TypeScript, I have had to adapt some changes to the logic in various files, most of which are just slight changes. Stuff like how in plugins like markdown-it-colour-text.ts, logic that previously relied on string comparisons (e.g., delim.marker === '##') was refactored to use numeric ASCII codes (e.g., delim.marker === 35 && delim.close).
As this is my first time really working with converting JavaScript to TypeScript, do let me know if there are any things that I missed out/can be improved on.
