Release 1.0.2

Version 1.0.1 gave the search widget and copy button the same z-index. This change has been reversed so the search widget is always on top.

Release 1.0.1

• The background image on the unfold button no longer repeats vertically in Safari.
• A read-only editor's textarea no longer has user-select: none in Safari.
• Slightly improved styling for the search widget.

Release 1.0.0

New fatures

Added a code folding extension supporting read-only editors. You can see it in action in the last example on the demo page.

import "prism-code-editor/code-folding.css"
import { readOnlyCodeFolding } from "prism-code-editor/code-folding"

Added a read-only property extensions to the PrismEditor interface. This property can be used to access many of the extensions added to the editor.

Ctrl+] / [ can now also be used to indent/outdent lines (Cmd+] / [ on Mac).

Added tag matching, selection match highlighting and read-only code folding to the read-only setup.

Breaking changes

The numLines signature has been changed from: numLines: (str: string, position?: number) => number to numLines: (str: string, start?: number, end?: number) => number. This means that you'll need to change all calls to numLines with 2 arguments.

The defaultCommands extension's first argument has been removed since it's no longer necessary to pass the cursor extension to it.

The deprecated matchBrackets extension has been removed and replaced by the new bracket matcher. If you're already using the new bracket matcher, you'll need to rename it from bracketMatcher to matchBrackets. If you're using the old one, you might need to change the arguments and add the highlightBracketPairs extension.

--widget__bg-find custom property used to color search matches has been renamed to --search__bg-find.

Bug fixes

• prism-code-editor/prism-markdown and prism-code-editor/prism-core are now properly marked as having side-effects in package.json.
• Cursor position extension could incorrectly position the cursor with word wrap enabled.
• Empty search matches could be incorrectly positioned with word wrap enabled.
• editor.value could be stale when accessed in an extension update callback. This wasn't causing issues, but had the potensial to.
• Extensions no longer update if setOptions throws an error due to passing an invalid language

Release 0.3.0

New bracket matcher:

The old bracket matcher has been replaced with a faster and smaller one. Rainbow brackets are now optional and highlighting the closest bracket pair is handled by a separate extension.

import { bracketMatcher } from "prism-code-editor/match-brackets"
import { highlightBracketPairs } from "prism-code-editor/highlight-brackets"

I would've preferred to have highlightBracketPairs in the same package, but tree-shaking didn't work as expected when I did.

The old bracket matcher is kept for backwards compatibility, but is marked as deprecated and will be removed in the future.

Release 0.2.0

New features

Added a tag's ending position, its tag name and whether it's a self-closing tag to the tag matcher.

Fixes

Removed default button border from the copy button. This default border would only be present if there was no other CSS removing the border.

Release 0.1.1

Capitalized tags and fragments can now be matched together in JSX.

Release 0.1.0

New features:

• Added tokens as a read-only property to the PrismEditor interface
• Added a tag matching extension

import { createTagMatcher, matchTags } from "prism-code-editor/match-tags"

Fixes:

• Indentation guides now work properly without a monospace font

Minor changes:

--bg-indent-guide-active custom property has been removed. To color the active indentation guide, do something like this:

.guide-indents .active {
  --bg-guide-indent: #999;
}

Release 0.0.6

Improved searching:

• The textarea could still steal focus from the search widget in Safari. This has been fixed
• Fixed a typo in the search widget

Returning true inside key/input commands now also calls Event.stopImmediatePropagation

Release 0.0.5

Improved search widget:

• Improved logic for next/previous match buttons.
