V2 is released! 🎉

Some breaking changes are introduced. If you're migrating from V1 to V2, please read the migration guide.

V1 has been moved into its separate tree - a final maintenance release is published, but in general no more updates will be done.

It is highly recommended to upgrade to V2 - it is modern, much cleaner and much easier to reason with. To get some context as to why, please read the V2 release candidate release notes.

V2 features include:

• Automated hash-link scrolls
• Built-in FOUC prevention
• Automatically rewrite URLs relative to src
• Automatically re-render when src changes
• Support for >200 code languages with detection for unhinted code blocks
• Easy styling mechanism
• Highly extensible

Check out the V2 docs: https://zerodevx.github.io/zero-md/

• Maintenance update

• Update src attribute change behaviour.
• Add tick() function.
• Refactor goto() function.

• no-shadow is immutable and must be set at element creation time
• Update link handling logic

• Refactor dynamic script loading implementation
• Don't reflect no-shadow
• Slightly improve language detection

V2 is a re-write. It is feature-complete, so all existing V1 features (including those from contributors - thank you!) should also be found here. Some breaking changes are introduced.

Component changes:

• <xmp> tag support is dropped; use <script type="text/markdown"> instead - https://github.com/zerodevx/zero-md/pull/29#issuecomment-673305798
• De-dent is now opt-in via the data-dedent attribute like this: <script type="text/markdown" data-dedent>
• <zero-md> will always try to load from src attribute first; if it's falsy (no src attribute, src download fails, src is an empty file etc.), then it falls-back on <script type="text/markdown">.
• The attributes css-urls, prism-url and marked-url are removed. <zero-md> only accepts src, manual-render and no-shadow.
• <template> tags should now be used only to house styles. That includes <link rel="stylesheet"> (for loading external stylesheets), and standard <style> tags.
• Custom styles can now be merged in using <template data-merge="append | prepend"> - https://github.com/zerodevx/zero-md/issues/34
• Global configurations are set on window.ZeroMdConfig object instead.
• All relative URLs in markdown are now normalised to the src path - fixes https://github.com/zerodevx/zero-md/issues/22
• zero-md-marked-ready and zero-md-prism-ready custom events are dropped. Use zero-md-ready instead.
• There is now universal code highlighting for most languages, so a repeat of https://github.com/zerodevx/zero-md/issues/23 should not happen.
• <zero-md> now automatically re-renders if src changes, and manual-render is not set - https://github.com/zerodevx/zero-md/issues/26
• However, changes to <script type="text/markdown"> are not observed. This is best handled outside the remit of <zero-md> through a MutationObserver recipe.
• A zero-md-error custom event is now emitted if non-fatal HTTP errors are detected - https://github.com/zerodevx/zero-md/issues/31 - more will be written on this.

Tooling changes:

• Testing has undergone a major fat trim. None of that web-component-tester and selenium and headless-chrome with bower with fixture-element and all that bloatware. Really, you just need mocha and chai asserts and run them off your browser.
• Just write standardjs and move on.
• Rollup to watch, serve and build.
• Totally remove all remnants of HTMLImports (good riddance) and fixed package.json. ES imports should now work as expected - fixes https://github.com/zerodevx/zero-md/issues/25
• Renamed master to main.

• Add support for <script type="text/markdown"> with dedenting - thanks @bennypowers! (ref: #29)
• Update dependencies.

• Update dependencies.

• Fixed typo that broke C syntax highlighting - thanks @TheUnlocked! (ref: PR#21)
• Add usage note on webcomponentsjs polyfill regression in FFv60. (ref: #19)
• Update dependencies.

• Maintenance update of dev dependencies.
• New releases are a breeze now.

• Actually build for v1.3.1 (fixes #15).
• Automate the chore of version bumping else I keep missing things.

• Exposes the ZeroMd.config global to set default values applying to all instances of <zero-md> in the document. (Ref: PR#12) - thanks @bennypowers!
• Update default host CSS to help normalise behavior across browsers. Fixes #13 - thanks @bennypowers!
• Publish on NPM to support modern workflows per #11.

• Really fix meta-click links #8, thanks @ernsheong!
